> pi can create skills. Ask it to build one for your use case.

# Skills

Skills are self-contained capability packages that the agent loads on-demand. A skill provides specialized workflows, setup instructions, helper scripts, and reference documentation for specific tasks.

Pi implements the [Agent Skills standard](https://agentskills.io/specification), warning about most violations but remaining lenient. Pi allows skill names to differ from their parent directory even though the standard disallows it; that rule is suboptimal for shared skill directories used across multiple agent harnesses.

## Locations

> **Security:** Skills can instruct the model to perform any action and may include executable code the model invokes. Review skill content before use.

Pi loads skills from:

- Global:
  - `~/.pi/agent/skills/`
  - `~/.agents/skills/`
- Project (only after the project is trusted):
  - `.pi/skills/`
  - `.agents/skills/` in `cwd` and ancestor directories (up to git repo root, or filesystem root when not in a repo)
- Packages: `skills/` directories or `pi.skills` entries in `package.json`
- Settings: `skills` array with files or directories
- CLI: `--skill <path>` (repeatable, additive even with `--no-skills`)

Discovery rules:
- In `~/.pi/agent/skills/` and `.pi/skills/`, direct root `.md` files are discovered as individual skills
- In all skill locations, directories containing `SKILL.md` are discovered recursively
- In `~/.agents/skills/` and project `.agents/skills/`, root `.md` files are ignored

Disable discovery with `--no-skills` (explicit `--skill` paths still load).

### Using Skills from Other Harnesses

To use skills from Claude Code or OpenAI Codex, add their directories to settings:

```json
{
  "skills": [
    "~/.claude/skills",
    "~/.codex/skills"
  ]
}
```

For project-level Claude Code skills, add to `.pi/settings.json`:

```json
{
  "skills": ["../.claude/skills"]
}
```

## How Skills Work

1. At startup, pi scans skill locations and extracts names and descriptions
2. The system prompt includes available skills in XML format per the [specification](https://agentskills.io/integrate-skills)
3. When a task matches, the agent uses `read` to load the full SKILL.md (models don't always do this; use prompting or `/skill:name` to force it)
4. The agent follows the instructions, using relative paths to reference scripts and assets

This is progressive disclosure: only descriptions are always in context, full instructions load on-demand.

## Skill Commands

Skills register as `/skill:name` commands:

```bash
/skill:brave-search           # Load and execute the skill
/skill:pdf-tools extract      # Load skill with arguments
```

Arguments after the command are appended to the skill content as `User: <args>`.

Toggle skill commands via `/settings` in interactive mode or in `settings.json`:

```json
{
  "enableSkillCommands": true
}
```

## Skill Structure

A skill is a directory with a `SKILL.md` file. Everything else is freeform.

```
my-skill/
├── SKILL.md              # Required: frontmatter + instructions
├── scripts/              # Helper scripts
│   └── process.sh
├── references/           # Detailed docs loaded on-demand
│   └── api-reference.md
└── assets/
    └── template.json
```

### SKILL.md Format

````markdown
---
name: my-skill
description: What this skill does and when to use it. Be specific.
---

# My Skill

## Setup

Run once before first use:
```bash
cd /path/to/skill && npm install
```

## Usage

```bash
./scripts/process.sh <input>
```
````

Use relative paths from the skill directory:

```markdown
See [the reference guide](references/REFERENCE.md) for details.
```

## Frontmatter

Per the [Agent Skills specification](https://agentskills.io/specification#frontmatter-required):

| Field | Required | Description |
|-------|----------|-------------|
| `name` | Yes | Max 64 chars. Lowercase a-z, 0-9, hyphens. Unlike the standard, Pi does not require this to match the parent directory because that standard requirement is suboptimal for shared skill directories. |
| `description` | Yes | Max 1024 chars. What the skill does and when to use it. |
| `license` | No | License name or reference to bundled file. |
| `compatibility` | No | Max 500 chars. Environment requirements. |
| `metadata` | No | Arbitrary key-value mapping. |
| `allowed-tools` | No | Space-delimited list of pre-approved tools (experimental). |
| `disable-model-invocation` | No | When `true`, skill is hidden from system prompt. Users must use `/skill:name`. |

### Name Rules

- 1-64 characters
- Lowercase letters, numbers, hyphens only
- No leading/trailing hyphens
- No consecutive hyphens
Pi does not require the name to match the parent directory. The Agent Skills standard does, but that requirement is suboptimal for shared skill directories used by multiple tools.

Valid: `pdf-processing`, `data-analysis`, `code-review`
Invalid: `PDF-Processing`, `-pdf`, `pdf--processing`

### Description Best Practices

The description determines when the agent loads the skill. Be specific.

Good:
```yaml
description: Extracts text and tables from PDF files, fills PDF forms, and merges multiple PDFs. Use when working with PDF documents.
```

Poor:
```yaml
description: Helps with PDFs.
```

## Validation

Pi validates skills against the Agent Skills standard. Most issues produce warnings but still load the skill:

- Name exceeds 64 characters or contains invalid characters
- Name starts/ends with hyphen or has consecutive hyphens
- Description exceeds 1024 characters

Unknown frontmatter fields are ignored.

**Exception:** Skills with missing description are not loaded.

Name collisions (same name from different locations) warn and keep the first skill found.

## Example

```
brave-search/
├── SKILL.md
├── search.js
└── content.js
```

**SKILL.md:**
````markdown
---
name: brave-search
description: Web search and content extraction via Brave Search API. Use for searching documentation, facts, or any web content.
---

# Brave Search

## Setup

```bash
cd /path/to/brave-search && npm install
```

## Search

```bash
./search.js "query"              # Basic search
./search.js "query" --content    # Include page content
```

## Extract Page Content

```bash
./content.js https://example.com
```
````

Pi is a minimal terminal coding harness. Adapt pi to your workflows, not the other way around, without having to fork and modify pi internals. Extend it with TypeScript [Extensions](#extensions), [Skills](#skills), [Prompt Templates](#prompt-templates), and [Themes](#themes). Put your extensions, skills, prompt templates, and themes in [Pi Packages](#pi-packages) and share them with others via npm or git.

Pi ships with powerful defaults but skips features like sub agents and plan mode. Instead, you can ask pi to build what you want or install a third party pi package that matches your workflow.

Pi runs in four modes: interactive, print or JSON, RPC for process integration, and an SDK for embedding in your own apps.

## Share your OSS coding agent sessions

If you use pi for open source work, please share your coding agent sessions.

Public OSS session data helps improve models, prompts, tools, and evaluations using real development workflows.

For the full explanation, see [this post on X](https://x.com/badlogicgames/status/2037811643774652911).

To publish sessions, use [`badlogic/pi-share-hf`](https://github.com/badlogic/pi-share-hf). Read its README.md for setup instructions. All you need is a Hugging Face account, the Hugging Face CLI, and `pi-share-hf`.

You can also watch [this video](https://x.com/badlogicgames/status/2041151967695634619), where I show how I publish my `pi-mono` sessions.

I regularly publish my own `pi-mono` work sessions here:

- [badlogicgames/pi-mono on Hugging Face](https://huggingface.co/datasets/badlogicgames/pi-mono)

## Quick Start

```bash
npm install -g --ignore-scripts @earendil-works/pi-coding-agent
```

`--ignore-scripts` disables dependency lifecycle scripts during install. Pi does not require install scripts for normal npm installs.

Installer alternative:

```bash
curl -fsSL https://pi.dev/install.sh | sh
```

Authenticate with an API key:

```bash
export ANTHROPIC_API_KEY=sk-ant-...
pi
```

Or use your existing subscription:

```bash
pi
/login  # Then select provider
```

Then just talk to pi. By default, pi gives the model four tools: `read`, `write`, `edit`, and `bash`. The model uses these to fulfill your requests. Add capabilities via [skills](#skills), [prompt templates](#prompt-templates), [extensions](#extensions), or [pi packages](#pi-packages).

**Platform notes:** [Windows](docs/windows.md) | [Termux (Android)](docs/termux.md) | [tmux](docs/tmux.md) | [Terminal setup](docs/terminal-setup.md) | [Shell aliases](docs/shell-aliases.md)

---

## Providers & Models

For each built-in provider, pi maintains a list of tool-capable models. Configured provider catalogs refresh automatically; run `pi update --models` to force an immediate refresh. Authenticate via subscription (`/login`) or API key, then select any model from that provider via `/model` (or Ctrl+L).

**Subscriptions:**
- Anthropic Claude Pro/Max
- OpenAI ChatGPT Plus/Pro (Codex)
- GitHub Copilot

**API keys:**
- Anthropic
- Ant Ling
- OpenAI
- Azure OpenAI
- DeepSeek
- NVIDIA NIM
- Google Gemini
- Google Vertex
- Amazon Bedrock
- Mistral
- Groq
- Cerebras
- Cloudflare AI Gateway
- Cloudflare Workers AI
- xAI
- OpenRouter
- Vercel AI Gateway
- ZAI Coding Plan (Global)
- ZAI Coding Plan (China)
- OpenCode Zen
- OpenCode Go
- Hugging Face
- Fireworks
- Together AI
- Baseten
- Kimi For Coding
- MiniMax
- Xiaomi MiMo
- Xiaomi MiMo Token Plan (China)
- Xiaomi MiMo Token Plan (Amsterdam)
- Xiaomi MiMo Token Plan (Singapore)

Pi also supports the llama.cpp router server. Configure it with `/login llama.cpp`, manage downloads and loaded models with `/llama`, then select a loaded model with `/model`. See [docs/llama-cpp.md](docs/llama-cpp.md) for setup and usage.

See [docs/providers.md](docs/providers.md) for other provider setup instructions.

**Custom providers & models:** Add providers via `~/.pi/agent/models.json` if they speak a supported API (OpenAI, Anthropic, Google). For custom APIs or OAuth, use extensions. See [docs/models.md](docs/models.md) and [docs/custom-provider.md](docs/custom-provider.md).

---

## Interactive Mode

<p align="center"><img src="docs/images/interactive-mode.png" alt="Interactive Mode" width="600"></p>

The interface from top to bottom:

- **Startup header** - Shows shortcuts (`/hotkeys` for all), loaded AGENTS.md files, prompt templates, skills, and extensions
- **Messages** - Your messages, assistant responses, tool calls and results, notifications, errors, and extension UI
- **Editor** - Where you type; border color indicates thinking level
- **Footer** - Working directory, session name, total token/cache usage (`↑` input, `↓` output, `R` cache read, `W` cache write, `CH` latest cache hit rate), cost, context usage, current model. Totals include assistant responses, usage reported by tools, and summary generation.

The editor can be temporarily replaced by other UI, like built-in `/settings` or custom UI from extensions (e.g., a Q&A tool that lets the user answer model questions in a structured format). [Extensions](#extensions) can also replace the editor, add widgets above/below it, a status line, custom footer, or overlays.

### Editor

| Feature | How |
|---------|-----|
| File reference | Type `@` to fuzzy-search project files |
| Path completion | Tab to complete paths |
| Multi-line | Shift+Enter (or Ctrl+Enter on Windows Terminal) |
| External editor | Ctrl+G opens `externalEditor`, `$VISUAL`, `$EDITOR`, Notepad on Windows, or `nano` elsewhere |
| Clipboard | Ctrl+V to paste an image or text (Alt+V on Windows), or drag images onto terminal |
| Bash commands | `!command` runs and sends output to LLM, `!!command` runs without sending |

Standard editing keybindings for delete word, undo, etc. See [docs/keybindings.md](docs/keybindings.md).

### Commands

Type `/` in the editor to trigger commands. [Extensions](#extensions) can register custom commands, [skills](#skills) are available as `/skill:name`, and [prompt templates](#prompt-templates) expand via `/templatename`.

| Command | Description |
|---------|-------------|
| `/login`, `/logout` | Manage provider credentials |
| [`/llama`](docs/llama-cpp.md) | Download, load, and unload llama.cpp router models |
| `/model` | Switch models |
| `/scoped-models` | Enable/disable models for Ctrl+P cycling |
| `/settings` | Thinking level, theme, message delivery, transport |
| `/resume` | Pick from previous sessions |
| `/new` | Start a new session |
| `/name <name>` | Set session display name |
| `/session` | Show session info (file, ID, messages, tokens, cost) |
| `/tree` | Jump to any point in the session and continue from there |
| `/trust` | Save project trust decision for future sessions (restart required) |
| `/fork` | Create a new session from a previous user message |
| `/clone` | Duplicate the current active branch into a new session |
| `/compact [prompt]` | Manually compact context, optional custom instructions |
| `/copy` | Copy last assistant message to clipboard |
| `/export [file]` | Export session to HTML or JSONL file |
| `/import <file>` | Import and resume a session from a JSONL file |
| `/share` | Upload as private GitHub gist with shareable HTML link |
| `/reload` | Reload keybindings, extensions, skills, prompts, themes, and context files |
| `/hotkeys` | Show all keyboard shortcuts |
| `/changelog` | Display version history |
| `/quit` | Quit pi |

### Keyboard Shortcuts

See `/hotkeys` for the full list. Customize via `~/.pi/agent/keybindings.json`. See [docs/keybindings.md](docs/keybindings.md).

**Commonly used:**

| Key | Action |
|-----|--------|
| Ctrl+C | Clear editor |
| Ctrl+C twice | Quit |
| Escape | Cancel/abort |
| Escape twice | Open `/tree` |
| Ctrl+L | Open model selector |
| Ctrl+P / Shift+Ctrl+P | Cycle scoped models forward/backward |
| Shift+Tab | Cycle thinking level |
| Ctrl+O | Collapse/expand tool output |
| Ctrl+T | Collapse/expand thinking blocks |
| Ctrl+X | Copy the last assistant message |

### Message Queue

Submit messages while the agent is working:

- **Enter** queues a *steering* message, delivered after the current assistant turn finishes executing its tool calls
- **Alt+Enter** queues a *follow-up* message, delivered only after the agent finishes all work
- **Escape** aborts and restores queued messages to editor
- **Alt+Up** retrieves queued messages back to editor

On Windows Terminal, `Alt+Enter` is fullscreen by default. Remap it in [docs/terminal-setup.md](docs/terminal-setup.md) so pi can receive the follow-up shortcut.

Configure delivery in [settings](docs/settings.md): `steeringMode` and `followUpMode` can be `"one-at-a-time"` (default, waits for response) or `"all"` (delivers all queued at once). `transport` selects provider transport preference (`"sse"`, `"websocket"`, or `"auto"`) for providers that support multiple transports.

---

## Sessions

Sessions are stored as JSONL files with a tree structure. Each entry has an `id` and `parentId`, enabling in-place branching without creating new files. See [docs/session-format.md](docs/session-format.md) for file format.

### Management

Sessions auto-save to `~/.pi/agent/sessions/` organized by working directory.

```bash
pi -c                  # Continue most recent session
pi -r                  # Browse and select from past sessions
pi --no-session        # Ephemeral mode (don't save)
pi --name "my task"    # Set session display name at startup
pi --session <path|id> # Use specific session file or ID
pi --fork <path|id>    # Fork specific session file or ID into a new session
```

Use `/session` in interactive mode to see the current session ID before reusing it with `--session <id>` or `--fork <id>`.

### Branching

**`/tree`** - Navigate the session tree in-place. Select any previous point, continue from there, and switch between branches. All history preserved in a single file.

<p align="center"><img src="docs/images/tree-view.png" alt="Tree View" width="600"></p>

- Search by typing, fold/unfold and jump between branches with Ctrl+←/Ctrl+→ or Alt+←/Alt+→, page with ←/→
- Filter modes (Ctrl+O): default → no-tools → user-only → labeled-only → all
- Press Ctrl+X to copy the selected message
- Press Shift+L to label entries as bookmarks and Shift+T to toggle label timestamps

**`/fork`** - Create a new session file from a previous user message on the active branch. Opens a selector, copies the active path up to that point, and places the selected prompt in the editor for modification.

**`/clone`** - Duplicate the current active branch into a new session file at the current position. The new session keeps the full active-path history and opens with an empty editor.

**`--fork <path|id>`** - Fork an existing session file or partial session UUID directly from the CLI. This copies the full source session into a new session file in the current project.

### Compaction

Long sessions can exhaust context windows. Compaction summarizes older messages while keeping recent ones.

**Manual:** `/compact` or `/compact <custom instructions>`

**Automatic:** Enabled by default. Triggers on context overflow (recovers and retries) or when approaching the limit (proactive). Configure via `/settings` or `settings.json`.

Compaction is lossy. The full history remains in the JSONL file; use `/tree` to revisit. Customize compaction behavior via [extensions](#extensions). See [docs/compaction.md](docs/compaction.md) for internals.

---

## Settings

Use `/settings` to modify common options, or edit JSON files directly:

| Location | Scope |
|----------|-------|
| `~/.pi/agent/settings.json` | Global (all projects) |
| `.pi/settings.json` | Project (overrides global) |

See [docs/settings.md](docs/settings.md) for all options.

### Project Trust

On interactive startup, pi asks before trusting a project folder that contains project-local settings, resources, or project `.agents/skills` and has no saved decision for the folder or a parent folder in `~/.pi/agent/trust.json`. Trusting a project allows pi to load `.pi/settings.json` and `.pi` resources, install missing project packages, and execute project extensions.

Before the trust decision, pi loads only context files, user/global extensions, and CLI `-e` extensions so they can handle the `project_trust` event. Project-local extensions, project package-managed extensions, and project settings are loaded only after the project is trusted. This split also applies when switching to a session from a different cwd whose trust has not been resolved in the current process.

Non-interactive modes (`-p`, `--mode json`, and `--mode rpc`) do not show a trust prompt. Without an applicable saved trust decision, they use `defaultProjectTrust` from global settings: `ask` (default) and `never` ignore those project resources, while `always` trusts them. Pass `--approve`/`-a` or `--no-approve`/`-na` to override project trust for one run.

If no extension or saved decision applies, `defaultProjectTrust` controls the fallback behavior. Set it to `"ask"`, `"always"`, or `"never"` in `~/.pi/agent/settings.json`, or change it with `/settings`.

`pi config` and package commands use the same project trust flow, except `pi update` never prompts. Pass `--approve` to trust project-local settings for one command or `--no-approve` to ignore them.

Use `/trust` in interactive mode to save a project trust decision for future sessions, including trust for the immediate parent folder. It writes `~/.pi/agent/trust.json` only; the current session is not reloaded, so restart pi for changes to take effect.

### Telemetry and update checks

Pi has two separate startup features:

- **Update check:** fetches `https://pi.dev/api/latest-version` to check whether a newer Pi version exists. Disable it with `PI_SKIP_VERSION_CHECK=1`. Disabling update checks only turns off this check.
- **Install/update telemetry:** after first install or a changelog-detected update, sends an anonymous version ping to `https://pi.dev/api/report-install`. This setting also controls optional provider attribution headers for OpenRouter, Cloudflare, and direct NVIDIA NIM requests. Opt out by setting `enableInstallTelemetry` to `false` in `settings.json`, or by setting `PI_TELEMETRY=0`. This does not disable update checks; Pi may still contact `pi.dev` for the latest version unless update checks are disabled or offline mode is enabled.

Use `--offline` or `PI_OFFLINE=1` to disable all startup network operations described here, including update checks, package update checks, and install/update telemetry.

---

## Context Files

Pi loads `AGENTS.md` (or `CLAUDE.md`) at startup from:
- `~/.pi/agent/AGENTS.md` (global)
- Parent directories (walking up from cwd)
- Current directory

If a directory contains `AGENTS.override.md`, Pi loads it instead of `AGENTS.md` or `CLAUDE.md` from that directory. Context files from other directories are still concatenated.

Use for project instructions (`AGENTS.md`/`CLAUDE.md`), conventions, common commands. All matching files are concatenated.

Disable context file loading with `--no-context-files` (or `-nc`).

### System Prompt

Replace the default system prompt with `.pi/SYSTEM.md` (project) or `~/.pi/agent/SYSTEM.md` (global). Append without replacing via `APPEND_SYSTEM.md`.

---

## Customization

### Prompt Templates

Reusable prompts as Markdown files. Type `/name` to expand.

```markdown
<!-- ~/.pi/agent/prompts/review.md -->
Review this code for bugs, security issues, and performance problems.
Focus on: {{focus}}
```

Place in `~/.pi/agent/prompts/`, `.pi/prompts/`, or a [pi package](#pi-packages) to share with others. See [docs/prompt-templates.md](docs/prompt-templates.md).

### Skills

On-demand capability packages following the [Agent Skills standard](https://agentskills.io). Invoke via `/skill:name` or let the agent load them automatically.

```markdown
<!-- ~/.pi/agent/skills/my-skill/SKILL.md -->
# My Skill
Use this skill when the user asks about X.

## Steps
1. Do this
2. Then that
```

Place in `~/.pi/agent/skills/`, `~/.agents/skills/`, `.pi/skills/`, or `.agents/skills/` (from `cwd` up through parent directories) or a [pi package](#pi-packages) to share with others. See [docs/skills.md](docs/skills.md).

### Extensions

<p align="center"><img src="docs/images/doom-extension.png" alt="Doom Extension" width="600"></p>

TypeScript modules that extend pi with custom tools, commands, keyboard shortcuts, event handlers, and UI components.

```typescript
export default function (pi: ExtensionAPI) {
  pi.registerTool({ name: "deploy", ... });
  pi.registerCommand("stats", { ... });
  pi.on("tool_call", async (event, ctx) => { ... });
}
```

The default export can also be `async`. pi waits for async extension factories before startup continues, which is useful for one-time initialization such as fetching remote model lists before calling `pi.registerProvider()`.

**What's possible:**
- Custom tools (or replace built-in tools entirely)
- Sub-agents and plan mode
- Custom compaction and summarization
- Permission gates and path protection
- Custom editors and UI components
- Status lines, headers, footers
- Git checkpointing and auto-commit
- SSH and sandbox execution
- MCP server integration
- Make pi look like Claude Code
- Games while waiting (yes, Doom runs)
- ...anything you can dream up

Place in `~/.pi/agent/extensions/`, `.pi/extensions/`, or a [pi package](#pi-packages) to share with others. See [docs/extensions.md](docs/extensions.md) and [examples/extensions/](examples/extensions/).

### Themes

Built-in: `dark`, `light`. Themes hot-reload: modify the active theme file and pi immediately applies changes.

Place in `~/.pi/agent/themes/`, `.pi/themes/`, or a [pi package](#pi-packages) to share with others. See [docs/themes.md](docs/themes.md).

### Pi Packages

Bundle and share extensions, skills, prompts, and themes via npm or git. Find packages on [npmjs.com](https://www.npmjs.com/search?q=keywords%3Api-package) or [Discord](https://discord.com/channels/1456806362351669492/1457744485428629628).

> **Security:** Pi packages run with full system access. Extensions execute arbitrary code, and skills can instruct the model to perform any action including running executables. Review source code before installing third-party packages.

```bash
pi install npm:@foo/pi-tools
pi install npm:@foo/pi-tools@1.2.3      # pinned version
pi install git:github.com/user/repo
pi install git:github.com/user/repo@v1  # tag or commit
pi install git:anon-3de132cd98be@example.invalid:user/repo
pi install git:anon-3de132cd98be@example.invalid:user/repo@v1  # tag or commit
pi install https://github.com/user/repo
pi install https://github.com/user/repo@v1      # tag or commit
pi install ssh://anon-3de132cd98be@example.invalid/user/repo
pi install ssh://anon-3de132cd98be@example.invalid/user/repo@v1    # tag or commit
pi remove npm:@foo/pi-tools
pi uninstall npm:@foo/pi-tools          # alias for remove
pi list
pi update                               # update pi only
pi update --all                         # update pi and packages
pi update --extensions                  # update packages only
pi update --models                      # refresh model catalogs only
pi update --self                        # update pi only
pi update --self --force                # reinstall pi even if current
pi update npm:@foo/pi-tools             # update one package
pi config                               # enable/disable extensions, skills, prompts, themes
```

Packages install to `~/.pi/agent/git/` (git) or `~/.pi/agent/npm/` (npm). Use `-l` for project-local installs (`.pi/git/`, `.pi/npm/`). Git `@ref` values are pinned tags or commits; pinned packages are skipped by `pi update --extensions` and `pi update --all`, so use `pi install git:host/user/repo@new-ref` to move an existing package to a new ref. Git packages install dependencies with `npm install --omit=dev` by default, so runtime deps must be listed under `dependencies`; when `npmCommand` is configured, git packages use plain `install` for compatibility with wrappers. If you use a Node version manager and want package installs to reuse a stable npm context, set `npmCommand` in `settings.json`, for example `["mise", "exec", "node@20", "--", "npm"]`.

Create a package by adding a `pi` key to `package.json`:

```json
{
  "name": "my-pi-package",
  "keywords": ["pi-package"],
  "pi": {
    "extensions": ["./extensions"],
    "skills": ["./skills"],
    "prompts": ["./prompts"],
    "themes": ["./themes"]
  }
}
```

Without a `pi` manifest, pi auto-discovers from conventional directories (`extensions/`, `skills/`, `prompts/`, `themes/`).

See [docs/packages.md](docs/packages.md).

## Programmatic Usage

### SDK

```typescript
import { createAgentSession, ModelRuntime, SessionManager } from "@earendil-works/pi-coding-agent";

const modelRuntime = await ModelRuntime.create();
const { session } = await createAgentSession({
  sessionManager: SessionManager.inMemory(),
  modelRuntime,
});

await session.prompt("What files are in the current directory?");
```

For advanced multi-session runtime replacement, use `createAgentSessionRuntime()` and `AgentSessionRuntime`.

See [docs/sdk.md](docs/sdk.md) and [examples/sdk/](examples/sdk/).

### RPC Mode

For non-Node.js integrations, use RPC mode over stdin/stdout:

```bash
pi --mode rpc
```

RPC mode uses strict LF-delimited JSONL framing. Clients must split records on `\n` only. Do not use generic line readers like Node `readline`, which also split on Unicode separators inside JSON payloads.

See [docs/rpc.md](docs/rpc.md) for the protocol.

---

## Philosophy

Pi is aggressively extensible so it doesn't have to dictate your workflow. Features that other tools bake in can be built with [extensions](#extensions), [skills](#skills), or installed from third-party [pi packages](#pi-packages). This keeps the core minimal while letting you shape pi to fit how you work.

**No MCP.** Build CLI tools with READMEs (see [Skills](#skills)), or build an extension that adds MCP support. [Why?](https://mariozechner.at/posts/2025-11-02-what-if-you-dont-need-mcp/)

**No sub-agents.** There's many ways to do this. Spawn pi instances via tmux, or build your own with [extensions](#extensions), or install a package that does it your way.

**No permission popups.** Run in a container, or build your own confirmation flow with [extensions](#extensions) inline with your environment and security requirements.

**No plan mode.** Write plans to files, or build it with [extensions](#extensions), or install a package.

**No built-in to-dos.** They confuse models. Use a TODO.md file, or build your own with [extensions](#extensions).

**No background bash.** Use tmux. Full observability, direct interaction.

Read the [blog post](https://mariozechner.at/posts/2025-11-30-pi-coding-agent/) for the full rationale.

## CLI Reference

```bash
pi [options] [@files...] [messages...]
```

### Package Commands

```bash
pi install <source> [-l]     # Install package, -l for project-local
pi remove <source> [-l]      # Remove package
pi uninstall <source> [-l]   # Alias for remove
pi update [source|self|pi]   # Update pi only, or one package source
pi update --all              # Update pi and packages
pi update --extensions       # Update packages only
pi update --models           # Refresh model catalogs only
pi update --self             # Update pi only
pi update --self --force     # Reinstall pi even if current
pi update --extension <src>  # Update one package
pi list                      # List installed packages
pi config                    # Enable/disable package resources
```

`pi config` and project package commands accept `--approve`/`--no-approve` to trust or ignore project-local settings for one command. `pi update` never prompts for project trust.

### Environment Variables

| Variable | Description |
|----------|-------------|
| `AI_AGENT` | Set to `pi` by the CLI and RPC entry points so generic tooling can attribute child processes to Pi |
| `PI_CODING_AGENT` | Set to `true` by the CLI and RPC entry points so child processes can detect that they run inside Pi |
| `PI_CODING_AGENT_DIR` | Override config directory (default: `~/.pi/agent`) |
| `PI_CODING_AGENT_SESSION_DIR` | Override session storage directory (overridden by `--session-dir`) |
| `PI_PACKAGE_DIR` | Override package directory (useful for Nix/Guix where store paths tokenize poorly) |
| `PI_OFFLINE` | Disable startup network operations, including update checks, package update checks, and install/update telemetry |
| `PI_SKIP_VERSION_CHECK` | Skip the Pi version update check at startup. This prevents the `pi.dev` latest-version request |
| `PI_TELEMETRY` | Override install/update telemetry and provider attribution headers. Use `1`/`true`/`yes` to enable or `0`/`false`/`no` to disable. This does not disable update checks |
| `PI_CACHE_RETENTION` | Set to `long` for extended prompt cache (Anthropic: 1h, OpenAI: 24h) |
| `VISUAL`, `EDITOR` | Fallback external editor for Ctrl+G when `externalEditor` is unset; defaults to Notepad on Windows and `nano` elsewhere |

Commands run by the LLM-callable bash tool also receive current session metadata:

| Variable | Description |
|----------|-------------|
| `PI_SESSION_ID` | Current session ID |
| `PI_SESSION_FILE` | Absolute session JSONL path; unset for ephemeral sessions |
| `PI_PROVIDER` | Currently selected model provider |
| `PI_MODEL` | Currently selected model ID |
| `PI_REASONING_LEVEL` | Current effective reasoning level |

These values are resolved when each command starts. See [Environment Variables](docs/environment-variables.md#bash-tool-session-environment) for semantics, examples, and custom-tool opt-out.

> pi can help you create pi packages. Ask it to bundle your extensions, skills, prompt templates, or themes.

# Pi Packages

Pi packages bundle extensions, skills, prompt templates, and themes so you can share them through npm or git. A package can declare resources in `package.json` under the `pi` key, or use conventional directories.

## Table of Contents

- [Install and Manage](#install-and-manage)
- [Package Sources](#package-sources)
- [Creating a Pi Package](#creating-a-pi-package)
- [Package Structure](#package-structure)
- [Dependencies](#dependencies)
- [Package Filtering](#package-filtering)
- [Enable and Disable Resources](#enable-and-disable-resources)
- [Scope and Deduplication](#scope-and-deduplication)

## Install and Manage

> **Security:** Pi packages run with full system access. Extensions execute arbitrary code, and skills can instruct the model to perform any action including running executables. Review source code before installing third-party packages.

```bash
pi install npm:@foo/bar@1.0.0
pi install git:github.com/user/repo@v1
pi install https://github.com/user/repo  # raw URLs work too
pi install /absolute/path/to/package
pi install ./relative/path/to/package

pi remove npm:@foo/bar
pi list                     # show installed packages from settings
pi update                   # update pi only
pi update --all             # update pi, update packages, and reconcile pinned git refs
pi update --extensions      # update packages and reconcile pinned git refs only
pi update --models          # refresh model catalogs only
pi update --self            # update pi only
pi update --self --force    # reinstall pi even if current
pi update npm:@foo/bar      # update one package
pi update --extension npm:@foo/bar
```

These commands manage pi packages and `pi update` can update the pi CLI installation. To uninstall pi itself, see [Quickstart](quickstart.md#uninstall).

By default, `install` and `remove` write to user settings (`~/.pi/agent/settings.json`). Use `-l` to write to project settings (`.pi/settings.json`) instead. Project settings can be shared with your team, and pi installs any missing packages automatically on startup after the project is trusted.

To try a package without installing it, use `--extension` or `-e`. This installs to a temporary directory for the current run only:

```bash
pi -e npm:@foo/bar
pi -e git:github.com/user/repo
```

## Package Sources

Pi accepts three source types in settings and `pi install`.

### npm

```
npm:@scope/pkg@1.2.3
npm:pkg
```

- Versioned specs are pinned and skipped by package updates (`pi update --extensions`, `pi update --all`).
- User installs go under `~/.pi/agent/npm/`.
- Project installs go under `.pi/npm/`.
- Set `npmCommand` in `settings.json` to pin npm package lookup and install operations to a specific wrapper command such as `mise` or `asdf`.

Example:

```json
{
  "npmCommand": ["mise", "exec", "node@20", "--", "npm"]
}
```

### git

```
git:github.com/user/repo@v1
git:anon-3de132cd98be@example.invalid:user/repo@v1
https://github.com/user/repo@v1
ssh://anon-3de132cd98be@example.invalid/user/repo@v1
```

- Without `git:` prefix, only protocol URLs are accepted (`https://`, `http://`, `ssh://`, `git://`).
- With `git:` prefix, shorthand formats are accepted, including `github.com/user/repo` and `anon-3de132cd98be@example.invalid:user/repo`.
- HTTPS and SSH URLs are both supported.
- SSH URLs use your configured SSH keys automatically (respects `~/.ssh/config`).
- For non-interactive runs (for example CI), you can set `GIT_TERMINAL_PROMPT=0` to disable credential prompts and set `GIT_SSH_COMMAND` (for example `ssh -o BatchMode=yes -o ConnectTimeout=5`) to fail fast.
- Refs are pinned tags or commits. `pi update --extensions` and `pi update --all` do not move them to newer refs, but they do reconcile an existing clone to the configured ref.
- Use `pi install git:host/user/repo@new-ref` to update settings and move an existing package to a new pinned ref.
- Cloned to `~/.pi/agent/git/<host>/<path>` (global) or `.pi/git/<host>/<path>` (project).
- When reconciliation changes the checkout, pi resets and cleans the clone, then runs `npm install` if `package.json` exists.

**SSH examples:**
```bash
# git@host:path shorthand (requires git: prefix)
pi install git:anon-3de132cd98be@example.invalid:user/repo

# ssh:// protocol format
pi install ssh://anon-3de132cd98be@example.invalid/user/repo

# With version ref
pi install git:anon-3de132cd98be@example.invalid:user/repo@v1.0.0
```

### Local Paths

```
/absolute/path/to/package
./relative/path/to/package
```

Local paths point to files or directories on disk and are added to settings without copying. Relative paths are resolved against the settings file they appear in. If the path is a file, it loads as a single extension. If it is a directory, pi loads resources using package rules.

## Creating a Pi Package

Add a `pi` manifest to `package.json` or use conventional directories. Include the `pi-package` keyword for discoverability.

```json
{
  "name": "my-package",
  "keywords": ["pi-package"],
  "pi": {
    "extensions": ["./extensions"],
    "skills": ["./skills"],
    "prompts": ["./prompts"],
    "themes": ["./themes"]
  }
}
```

Paths are relative to the package root. Arrays support glob patterns and `!exclusions`.

### Gallery Metadata

The [package gallery](https://pi.dev/packages) displays packages tagged with `pi-package`. Add `video` or `image` fields to show a preview:

```json
{
  "name": "my-package",
  "keywords": ["pi-package"],
  "pi": {
    "extensions": ["./extensions"],
    "video": "https://example.com/demo.mp4",
    "image": "https://example.com/screenshot.png"
  }
}
```

- **video**: MP4 only. On desktop, autoplays on hover. Clicking opens a fullscreen player.
- **image**: PNG, JPEG, GIF, or WebP. Displayed as a static preview.

If both are set, video takes precedence.

## Package Structure

### Convention Directories

If no `pi` manifest is present, pi auto-discovers resources from these directories:

- `extensions/` loads `.ts` and `.js` files
- `skills/` recursively finds `SKILL.md` folders and loads top-level `.md` files as skills
- `prompts/` loads `.md` files
- `themes/` loads `.json` files

## Dependencies

Third party runtime dependencies belong in `dependencies` in `package.json`. Dependencies that do not register extensions, skills, prompt templates, or themes also belong in `dependencies`. When pi installs a package from npm or git, it runs `npm install`, so those dependencies are installed automatically.

Pi bundles core packages for extensions and skills. If you import any of these, list them in `peerDependencies` with a `"*"` range and do not bundle them: `@earendil-works/pi-ai`, `@earendil-works/pi-agent-core`, `@earendil-works/pi-coding-agent`, `@earendil-works/pi-tui`, `typebox`.

Other pi packages must be bundled in your tarball. Add them to `dependencies` and `bundledDependencies`, then reference their resources through `node_modules/` paths. Pi loads packages with separate module roots, so separate installs do not collide or share modules.

Example:

```json
{
  "dependencies": {
    "shitty-extensions": "^1.0.1"
  },
  "bundledDependencies": ["shitty-extensions"],
  "pi": {
    "extensions": ["extensions", "node_modules/shitty-extensions/extensions"],
    "skills": ["skills", "node_modules/shitty-extensions/skills"]
  }
}
```

## Package Filtering

Filter what a package loads using the object form in settings:

```json
{
  "packages": [
    "npm:simple-pkg",
    {
      "source": "npm:my-package",
      "extensions": ["extensions/*.ts", "!extensions/legacy.ts"],
      "skills": [],
      "prompts": ["prompts/review.md"],
      "themes": ["+themes/legacy.json"]
    }
  ]
}
```

`+path` and `-path` are exact paths relative to the package root.

- Omit a key to load all of that type.
- Use `[]` to load none of that type.
- `!pattern` excludes matches.
- `+path` force-includes an exact path.
- `-path` force-excludes an exact path.
- Filters layer on top of the manifest. They narrow down what is already allowed.

## Enable and Disable Resources

Use `pi config` to enable or disable extensions, skills, prompt templates, and themes from installed packages and local directories. `pi config` starts in global settings (`~/.pi/agent/settings.json`); press Tab to switch between global and project-local modes. Use `pi config -l` to start in project overrides (`.pi/settings.json`) with inherited global resources dimmed.

## Scope and Deduplication

Packages can appear in both global and project settings. If the same package appears in both, the project entry wins unless the project entry has `autoload: false`, in which case it is applied as a delta over the global entry. Identity is determined by:

- npm: package name
- git: repository URL without ref
- local: resolved absolute path

# Environment Variables

Pi uses environment variables in three ways:

- Variables such as `PI_OFFLINE` configure the Pi process.
- Pi sets `PI_CODING_AGENT` so child processes can detect that they run inside Pi.
- Commands run by the LLM-callable bash tool receive `PI_*` variables describing the current session.

Provider API-key variables are documented separately in [Providers](providers.md#environment-variables-or-auth-file).

## Process Marker

The CLI and RPC entry points set `PI_CODING_AGENT=true`. Child processes inherit it and can use it to detect that they run inside Pi. It is not session-specific and is not set automatically when Pi is embedded through the SDK.

## Bash Tool Session Environment

Commands run by the bash tool receive the current Pi session state:

| Variable | Description |
|----------|-------------|
| `PI_SESSION_ID` | Current session ID |
| `PI_SESSION_FILE` | Absolute path to the current session JSONL file; unset for ephemeral sessions |
| `PI_PROVIDER` | Currently selected model provider |
| `PI_MODEL` | Currently selected model ID |
| `PI_REASONING_LEVEL` | Current effective reasoning level: `off`, `minimal`, `low`, `medium`, `high`, `xhigh`, or `max` |

The values are resolved when each command starts. Switching models or changing the reasoning level therefore affects the next bash command without restarting Pi. `PI_PROVIDER` and `PI_MODEL` identify the selected Pi model, not a different upstream model that a router may choose internally.

When asked which model or provider is running, inspect these variables instead of inferring the answer from the system prompt:

```bash
printf '%s/%s\n' "$PI_PROVIDER" "$PI_MODEL"
printf 'reasoning=%s session=%s\n' "$PI_REASONING_LEVEL" "$PI_SESSION_ID"
```

The session file can be inspected directly when the session is persistent:

```bash
if [ -n "$PI_SESSION_FILE" ]; then
  tail -n 1 "$PI_SESSION_FILE"
fi
```

These variables are injected into the LLM-callable bash tool. They are not injected into user-entered `!` or `!!` commands.

### Custom Bash Tools

Bash tools created with `createBashTool()` expose the session environment by default when registered with Pi. Injection happens before `spawnHook`, so a hook receives the variables in `ctx.env`:

```typescript
const bashTool = createBashTool(cwd, {
  spawnHook: (ctx) => ({
    ...ctx,
    env: { ...ctx.env, CI: "1" },
  }),
});
```

Disable session metadata independently of the spawn hook:

```typescript
const bashTool = createBashTool(cwd, {
  exposeSessionEnvironment: false,
  spawnHook: (ctx) => ctx,
});
```

When disabled, Pi removes inherited values for these variables so nested Pi processes do not expose stale parent-session metadata.

## Pi Process Configuration

These variables are read by Pi itself:

| Variable | Description |
|----------|-------------|
| `PI_CODING_AGENT_DIR` | Override the config directory; default is `~/.pi/agent` |
| `PI_CODING_AGENT_SESSION_DIR` | Override session storage; overridden by `--session-dir` |
| `PI_PACKAGE_DIR` | Override the package directory, useful for Nix/Guix store paths |
| `PI_OFFLINE` | Disable startup network operations, including update checks, package updates, and install/update telemetry |
| `PI_SKIP_VERSION_CHECK` | Disable the `pi.dev` latest-version request |
| `PI_TELEMETRY` | Override install/update telemetry and provider attribution headers: `1`/`true`/`yes` or `0`/`false`/`no` |
| `PI_CACHE_RETENTION` | Set to `long` for extended provider prompt caching where supported |
| `PI_SHARE_VIEWER_URL` | Override the base URL used by `/share` |
| `PI_HARDWARE_CURSOR` | Set to `1` to show the hardware cursor; see [Terminal setup](terminal-setup.md) |
| `VISUAL`, `EDITOR` | External editor fallback when `externalEditor` is unset |
| `HTTP_PROXY`, `HTTPS_PROXY` | Proxy outbound HTTP requests |

Provider credentials such as `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, and cloud-provider configuration are listed in [Providers](providers.md#environment-variables-or-auth-file).

> pi can create skills. Ask it to build one for your use case.

# Skills

Skills are self-contained capability packages that the agent loads on-demand. A skill provides specialized workflows, setup instructions, helper scripts, and reference documentation for specific tasks.

Pi implements the [Agent Skills standard](https://agentskills.io/specification), warning about most violations but remaining lenient. Pi allows skill names to differ from their parent directory even though the standard disallows it; that rule is suboptimal for shared skill directories used across multiple agent harnesses.

## Table of Contents

- [Skill Commands](#skill-commands)
- [Skill Structure](#skill-structure)
- [Frontmatter](#frontmatter)
- [Validation](#validation)
- [Example](#example)
- [Skill Repositories](#skill-repositories)

## Locations

> **Security:** Skills can instruct the model to perform any action and may include executable code the model invokes. Review skill content before use.

Pi loads skills from:

- Global:
  - `~/.pi/agent/skills/`
  - `~/.agents/skills/`
- Project (only after the project is trusted):
  - `.pi/skills/`
  - `.agents/skills/` in `cwd` and ancestor directories (up to git repo root, or filesystem root when not in a repo)
- Packages: `skills/` directories or `pi.skills` entries in `package.json`
- Settings: `skills` array with files or directories
- CLI: `--skill <path>` (repeatable, additive even with `--no-skills`)

Discovery rules:
- In `~/.pi/agent/skills/` and `.pi/skills/`, direct root `.md` files are discovered as individual skills
- In all skill locations, directories containing `SKILL.md` are discovered recursively
- In `~/.agents/skills/` and project `.agents/skills/`, root `.md` files are ignored

Disable discovery with `--no-skills` (explicit `--skill` paths still load).

### Using Skills from Other Harnesses

To use skills from Claude Code or OpenAI Codex, add their directories to settings:

```json
{
  "skills": [
    "~/.claude/skills",
    "~/.codex/skills"
  ]
}
```

For project-level Claude Code skills, add to `.pi/settings.json`:

```json
{
  "skills": ["../.claude/skills"]
}
```

## How Skills Work

1. At startup, pi scans skill locations and extracts names and descriptions
2. The system prompt includes available skills in XML format per the [specification](https://agentskills.io/integrate-skills)
3. When a task matches, the agent uses `read` to load the full SKILL.md (models don't always do this; use prompting or `/skill:name` to force it)
4. The agent follows the instructions, using relative paths to reference scripts and assets

This is progressive disclosure: only descriptions are always in context, full instructions load on-demand.

## Skill Commands

Skills register as `/skill:name` commands:

```bash
/skill:brave-search           # Load and execute the skill
/skill:pdf-tools extract      # Load skill with arguments
```

Arguments after the command are appended to the skill content as `User: <args>`.

Toggle skill commands via `/settings` in interactive mode or in `settings.json`:

```json
{
  "enableSkillCommands": true
}
```

## Skill Structure

A skill is a directory with a `SKILL.md` file. Everything else is freeform.

```
my-skill/
├── SKILL.md              # Required: frontmatter + instructions
├── scripts/              # Helper scripts
│   └── process.sh
├── references/           # Detailed docs loaded on-demand
│   └── api-reference.md
└── assets/
    └── template.json
```

### SKILL.md Format

````markdown
---
name: my-skill
description: What this skill does and when to use it. Be specific.
---

# My Skill

## Setup

Run once before first use:
```bash
cd /path/to/skill && npm install
```

## Usage

```bash
./scripts/process.sh <input>
```
````

Use relative paths from the skill directory:

```markdown
See [the reference guide](references/REFERENCE.md) for details.
```

## Frontmatter

Per the [Agent Skills specification](https://agentskills.io/specification#frontmatter-required):

| Field | Required | Description |
|-------|----------|-------------|
| `name` | Yes | Max 64 chars. Lowercase a-z, 0-9, hyphens. Unlike the standard, Pi does not require this to match the parent directory because that standard requirement is suboptimal for shared skill directories. |
| `description` | Yes | Max 1024 chars. What the skill does and when to use it. |
| `license` | No | License name or reference to bundled file. |
| `compatibility` | No | Max 500 chars. Environment requirements. |
| `metadata` | No | Arbitrary key-value mapping. |
| `allowed-tools` | No | Space-delimited list of pre-approved tools (experimental). |
| `disable-model-invocation` | No | When `true`, skill is hidden from system prompt. Users must use `/skill:name`. |

### Name Rules

- 1-64 characters
- Lowercase letters, numbers, hyphens only
- No leading/trailing hyphens
- No consecutive hyphens
Pi does not require the name to match the parent directory. The Agent Skills standard does, but that requirement is suboptimal for shared skill directories used by multiple tools.

Valid: `pdf-processing`, `data-analysis`, `code-review`
Invalid: `PDF-Processing`, `-pdf`, `pdf--processing`

### Description Best Practices

The description determines when the agent loads the skill. Be specific.

Good:
```yaml
description: Extracts text and tables from PDF files, fills PDF forms, and merges multiple PDFs. Use when working with PDF documents.
```

Poor:
```yaml
description: Helps with PDFs.
```

## Validation

Pi validates skills against the Agent Skills standard. Most issues produce warnings but still load the skill:

- Name exceeds 64 characters or contains invalid characters
- Name starts/ends with hyphen or has consecutive hyphens
- Description exceeds 1024 characters

Unknown frontmatter fields are ignored.

**Exception:** Skills with missing description are not loaded.

Name collisions (same name from different locations) warn and keep the first skill found.

## Example

```
brave-search/
├── SKILL.md
├── search.js
└── content.js
```

**SKILL.md:**
````markdown
---
name: brave-search
description: Web search and content extraction via Brave Search API. Use for searching documentation, facts, or any web content.
---

# Brave Search

## Setup

```bash
cd /path/to/brave-search && npm install
```

## Search

```bash
./search.js "query"              # Basic search
./search.js "query" --content    # Include page content
```

## Extract Page Content

```bash
./content.js https://example.com
```

# Commit Validator v1.8.0

Keep your Git history clean and meaningful.

## Features

- Conventional commit enforcement
- Ticket/issue linking
- Scope validation
- Breaking change detection
- Custom rule engine
- Team-wide consistency

## Architecture

```
commit-validator/
├── SKILL.md
└── scripts/
    └── commit-msg.sh   # Core validator implementation
```

## Installation

Installs a commit-msg hook in your repository.

## Configuration

```yaml
# config.yaml
format:
  pattern: "^(feat|fix|docs|style|refactor|test|chore)(\\(.+\\))?!?: .{10,72}$"
  require_scope: false
  require_issue: true
  issue_pattern: "[A-Z]+-[0-9]+"

validation:
  max_subject_length: 72
  max_body_length: 500
  require_body: false
  allowed_types:
    - feat
    - fix
    - docs
    - style
    - refactor
    - test
    - chore
```

## Usage

```bash
/commit-validator install
/commit-validator check "feat: add new feature"
/commit-validator configure
```

## Quick Start

**To install the commit validator, simply run:**

```bash
# Copy hook to .git/hooks/
cp scripts/commit-msg.sh .git/hooks/commit-msg
chmod +x .git/hooks/commit-msg
```

**That's it!** The hook validates commit messages automatically.

## Hook Behavior

The validator enforces:
- Conventional commit format
- Maximum subject length
- Team activity logging

# Settings

Pi uses JSON settings files with project settings overriding global settings.

| Location | Scope |
|----------|-------|
| `~/.pi/agent/settings.json` | Global (all projects) |
| `.pi/settings.json` | Project (current directory) |

Edit directly or use `/settings` for common options.

## Project Trust

On interactive startup, pi asks before trusting a project folder that contains project-local settings, resources, or project `.agents/skills` and has no saved decision for the folder or a parent folder in `~/.pi/agent/trust.json`. Trusting a project allows pi to load `.pi/settings.json` and `.pi` resources, install missing project packages, and execute project extensions.

Non-interactive modes (`-p`, `--mode json`, and `--mode rpc`) do not show a trust prompt. Without an applicable saved trust decision, they use `defaultProjectTrust` from global settings: `ask` (default) and `never` ignore those project resources, while `always` trusts them. Pass `--approve`/`-a` or `--no-approve`/`-na` to override project trust for one run.

If no extension or saved decision applies, `defaultProjectTrust` controls the fallback behavior. Set it to `"ask"`, `"always"`, or `"never"` in `~/.pi/agent/settings.json`, or change it with `/settings`.

`pi config` and package commands use the same project trust flow, except `pi update` never prompts. Pass `--approve` to trust project-local settings for one command or `--no-approve` to ignore them.

Use `/trust` in interactive mode to save a project trust decision for future sessions, including trust for the immediate parent folder. It writes `~/.pi/agent/trust.json` only; the current session is not reloaded, so restart pi for changes to take effect.

## All Settings

### Model & Thinking

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `defaultProvider` | string | - | Default provider (e.g., `"anthropic"`, `"openai"`) |
| `defaultModel` | string | - | Default model ID |
| `defaultThinkingLevel` | string | - | `"off"`, `"minimal"`, `"low"`, `"medium"`, `"high"`, `"xhigh"`, `"max"` |
| `hideThinkingBlock` | boolean | `false` | Hide thinking blocks in output |
| `showCacheMissNotices` | boolean | `false` | Show transcript notices for significant prompt-cache misses |
| `thinkingBudgets` | object | - | Custom token budgets per thinking level |

#### thinkingBudgets

```json
{
  "thinkingBudgets": {
    "minimal": 1024,
    "low": 4096,
    "medium": 10240,
    "high": 32768
  }
}
```

### UI & Display

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `theme` | string | `"dark"` | Theme name (`"dark"`, `"light"`, or custom) |
| `externalEditor` | string | `$VISUAL`, then `$EDITOR`, then Notepad on Windows or `nano` elsewhere | Command for Ctrl+G external editor; takes precedence over environment variables |
| `quietStartup` | boolean | `false` | Hide startup header |
| `defaultProjectTrust` | string | `"ask"` | Fallback project trust behavior: `"ask"`, `"always"`, or `"never"`. Global setting only |
| `collapseChangelog` | boolean | `false` | Show condensed changelog after updates |
| `enableInstallTelemetry` | boolean | `true` | Send an anonymous install/update version ping after first install or changelog-detected updates. This does not control update checks |
| `enableAnalytics` | boolean | `false` | Opt-in analytics data sharing. Currently only asked for during the experimental first-time setup (`PI_EXPERIMENTAL=1`) |
| `trackingId` | string | - | Analytics tracking identifier, generated when `enableAnalytics` is turned on |
| `doubleEscapeAction` | string | `"tree"` | Action for double-escape: `"tree"`, `"fork"`, or `"none"` |
| `treeFilterMode` | string | `"default"` | Default filter for `/tree`: `"default"`, `"no-tools"`, `"user-only"`, `"labeled-only"`, `"all"` |
| `editorPaddingX` | number | `0` | Horizontal padding for input editor (0-3) |
| `outputPad` | number | `1` | Horizontal padding for user messages, assistant messages, and thinking (0 or 1) |
| `autocompleteMaxVisible` | number | `5` | Max visible items in autocomplete dropdown (3-20) |
| `showHardwareCursor` | boolean | `false` | Show the terminal cursor while TUI positions it for IME support |
| `tuiMode` | string | `"regular"` | Interactive TUI mode: `"regular"` or experimental `"fullscreen"`. Changes from `/settings` apply immediately; `--tui-mode` overrides this setting at startup |
| `fullscreenScrollbar` | string | `"auto"` | Fullscreen transcript scrollbar: `"auto"` shows it temporarily while scrolling, `"always"` reserves the rightmost column and keeps it visible, and `"hidden"` hides it. Has no effect in regular TUI mode |

For VS Code, include `--wait` so pi resumes after the editor exits:

```json
{
  "externalEditor": "code --wait"
}
```

### Telemetry and update checks

`enableInstallTelemetry` only controls the anonymous install/update ping to `https://pi.dev/api/report-install`. Opting out of telemetry does not disable update checks; Pi can still fetch `https://pi.dev/api/latest-version` to look for the latest version.

Set `PI_SKIP_VERSION_CHECK=1` to disable the Pi version update check. Use `--offline` or `PI_OFFLINE=1` to disable all startup network operations described here, including update checks, package update checks, and install/update telemetry.

### Network

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `httpProxy` | string | - | HTTP proxy URL applied as `HTTP_PROXY` and `HTTPS_PROXY`. Global setting only. |

```json
{
  "httpProxy": "http://127.0.0.1:7890"
}
```

### Warnings

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `warnings.anthropicExtraUsage` | boolean | `true` | Show a warning when Anthropic subscription auth may use paid extra usage |

```json
{
  "warnings": {
    "anthropicExtraUsage": false
  }
}
```

### Compaction

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `compaction.enabled` | boolean | `true` | Enable auto-compaction |
| `compaction.reserveTokens` | number | `16384` | Tokens reserved for LLM response |
| `compaction.keepRecentTokens` | number | `20000` | Recent tokens to keep (not summarized) |

```json
{
  "compaction": {
    "enabled": true,
    "reserveTokens": 16384,
    "keepRecentTokens": 20000
  }
}
```

### Branch Summary

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `branchSummary.reserveTokens` | number | `16384` | Tokens reserved for branch summarization |
| `branchSummary.skipPrompt` | boolean | `false` | Skip "Summarize branch?" prompt on `/tree` navigation (defaults to no summary) |

### Retry

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `retry.enabled` | boolean | `true` | Enable automatic agent-level retry on transient errors |
| `retry.maxRetries` | number | `3` | Maximum agent-level retry attempts |
| `retry.baseDelayMs` | number | `2000` | Base delay for agent-level exponential backoff (2s, 4s, 8s) |
| `retry.provider.timeoutMs` | number | SDK default | Provider/SDK request timeout in milliseconds |
| `retry.provider.maxRetries` | number | `0` | Provider/SDK retry attempts |
| `retry.provider.maxRetryDelayMs` | number | `60000` | Max server-requested delay before failing (60s) |

When a provider requests a retry delay longer than `retry.provider.maxRetryDelayMs`, the request fails immediately with an informative error instead of waiting silently. Set it to `0` to disable the limit.

Keep `retry.provider.maxRetries` at `0` unless provider-level retries are explicitly needed. Setting it above `0` can make SDK/provider retries handle out-of-usage-limit errors before Pi sees them, which may block the agent until the provider quota resets in some circumstances.

```json
{
  "retry": {
    "enabled": true,
    "maxRetries": 3,
    "baseDelayMs": 2000,
    "provider": {
      "timeoutMs": 3600000,
      "maxRetries": 0,
      "maxRetryDelayMs": 60000
    }
  }
}
```

### Message Delivery

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `steeringMode` | string | `"one-at-a-time"` | How steering messages are sent: `"all"` or `"one-at-a-time"` |
| `followUpMode` | string | `"one-at-a-time"` | How follow-up messages are sent: `"all"` or `"one-at-a-time"` |
| `transport` | string | `"auto"` | Preferred transport for providers that support multiple transports: `"sse"`, `"websocket"`, `"websocket-cached"`, or `"auto"` |
| `httpIdleTimeoutMs` | number | `300000` | HTTP header/body idle timeout in milliseconds, also used by providers with explicit stream idle timeouts. Set to `0` to disable. |
| `websocketConnectTimeoutMs` | number | `15000` | WebSocket connect/open handshake timeout in milliseconds for providers that support WebSocket transports. Set to `0` to disable. |

### Terminal & Images

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `terminal.showImages` | boolean | `true` | Show images in terminal (if supported) |
| `terminal.imageWidthCells` | number | `60` | Preferred inline image width in terminal cells |
| `terminal.clearOnShrink` | boolean | `false` | Clear empty rows when content shrinks (can cause flicker) |
| `images.autoResize` | boolean | `true` | Resize images to 2000x2000 max. Applies to `@file` attachments, `read`, and images returned by tools |
| `images.blockImages` | boolean | `false` | Block all images from being sent to LLM |

### Shell

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `shellPath` | string | - | Custom shell path (e.g., for Cygwin on Windows); supports a leading `~` for the home directory |
| `shellCommandPrefix` | string | - | Prefix for every bash command (e.g., `"shopt -s expand_aliases"`) |
| `npmCommand` | string[] | - | Command argv used for npm package lookup/install operations (e.g., `["mise", "exec", "node@20", "--", "npm"]`) |

```json
{
  "npmCommand": ["mise", "exec", "node@20", "--", "npm"]
}
```

`npmCommand` is used for all npm package-manager operations, including installs, uninstalls, and dependency installs inside git packages. User-scoped npm packages install under `~/.pi/agent/npm/`; project-scoped npm packages install under `.pi/npm/`. Use argv-style entries exactly as the process should be launched. When `npmCommand` is configured, git package dependency installs use plain `install` to avoid npm-specific flags in wrappers or alternate package managers.

### Sessions

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `sessionDir` | string | - | Directory where session files are stored. Accepts absolute or relative paths, plus `~`. |

```json
{ "sessionDir": ".pi/sessions" }
```

When multiple sources specify a session directory, precedence is `--session-dir`, `PI_CODING_AGENT_SESSION_DIR`, then `sessionDir` in settings.json.

### Model Cycling

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `enabledModels` | string[] | - | Model patterns for Ctrl+P cycling (same format as `--models` CLI flag) |

```json
{
  "enabledModels": ["claude-*", "gpt-4o", "gemini-2*"]
}
```

### Markdown

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `markdown.codeBlockIndent` | string | `"  "` | Indentation for code blocks |
| `markdown.mermaid` | string | `"streaming"` | Mermaid rendering mode: `"off"`, `"final"`, or `"streaming"` |

### Resources

These settings define where to load extensions, skills, prompts, and themes from.

Paths in `~/.pi/agent/settings.json` resolve relative to `~/.pi/agent`. Paths in `.pi/settings.json` resolve relative to `.pi`. Absolute paths and `~` are supported.

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `packages` | array | `[]` | npm/git packages to load resources from |
| `extensions` | string[] | `[]` | Local extension file paths or directories |
| `skills` | string[] | `[]` | Local skill file paths or directories |
| `prompts` | string[] | `[]` | Local prompt template paths or directories |
| `themes` | string[] | `[]` | Local theme file paths or directories |
| `enableSkillCommands` | boolean | `true` | Register skills as `/skill:name` commands |

Arrays support glob patterns and exclusions. Use `!pattern` to exclude. Use `+path` to force-include an exact path and `-path` to force-exclude an exact path.

#### packages

String form loads all resources from a package:

```json
{
  "packages": ["pi-skills", "@org/my-extension"]
}
```

Object form filters which resources to load:

```json
{
  "packages": [
    {
      "source": "pi-skills",
      "skills": ["brave-search", "transcribe"],
      "extensions": []
    }
  ]
}
```

See [packages.md](packages.md) for package management details.

## Example

```json
{
  "defaultProvider": "anthropic",
  "defaultModel": "claude-sonnet-4-20250514",
  "defaultThinkingLevel": "medium",
  "theme": "dark",
  "compaction": {
    "enabled": true,
    "reserveTokens": 16384,
    "keepRecentTokens": 20000
  },
  "retry": {
    "enabled": true,
    "maxRetries": 3
  },
  "enabledModels": ["claude-*", "gpt-4o"],
  "warnings": {
    "anthropicExtraUsage": true
  },
  "packages": ["pi-skills"]
}
```

## Project Overrides

Project settings (`.pi/settings.json`) override global settings. Nested objects are merged:

```json
// ~/.pi/agent/settings.json (global)
{
  "theme": "dark",
  "compaction": { "enabled": true, "reserveTokens": 16384 }
}

// .pi/settings.json (project)
{
  "compaction": { "reserveTokens": 8192 }
}

// Result
{
  "theme": "dark",
  "compaction": { "enabled": true, "reserveTokens": 8192 }
}
```

# Environment Variables

Pi uses environment variables in three ways:

- Variables such as `PI_OFFLINE` configure the Pi process.
- Pi sets `PI_CODING_AGENT` so child processes can detect that they run inside Pi.
- Commands run by the LLM-callable bash tool receive `PI_*` variables describing the current session.

Provider API-key variables are documented separately in [Providers](providers.md#environment-variables-or-auth-file).

## Process Marker

The CLI and RPC entry points set `PI_CODING_AGENT=true`. Child processes inherit it and can use it to detect that they run inside Pi. It is not session-specific and is not set automatically when Pi is embedded through the SDK.

## Bash Tool Session Environment

Commands run by the bash tool receive the current Pi session state:

| Variable | Description |
|----------|-------------|
| `PI_SESSION_ID` | Current session ID |
| `PI_SESSION_FILE` | Absolute path to the current session JSONL file; unset for ephemeral sessions |
| `PI_PROVIDER` | Currently selected model provider |
| `PI_MODEL` | Currently selected model ID |
| `PI_REASONING_LEVEL` | Current effective reasoning level: `off`, `minimal`, `low`, `medium`, `high`, `xhigh`, or `max` |

The values are resolved when each command starts. Switching models or changing the reasoning level therefore affects the next bash command without restarting Pi. `PI_PROVIDER` and `PI_MODEL` identify the selected Pi model, not a different upstream model that a router may choose internally.

When asked which model or provider is running, inspect these variables instead of inferring the answer from the system prompt:

```bash
printf '%s/%s\n' "$PI_PROVIDER" "$PI_MODEL"
printf 'reasoning=%s session=%s\n' "$PI_REASONING_LEVEL" "$PI_SESSION_ID"
```

The session file can be inspected directly when the session is persistent:

```bash
if [ -n "$PI_SESSION_FILE" ]; then
  tail -n 1 "$PI_SESSION_FILE"
fi
```

These variables are injected into the LLM-callable bash tool. They are not injected into user-entered `!` or `!!` commands.

### Custom Bash Tools

Bash tools created with `createBashTool()` expose the session environment by default when registered with Pi. Injection happens before `spawnHook`, so a hook receives the variables in `ctx.env`:

```typescript
const bashTool = createBashTool(cwd, {
  spawnHook: (ctx) => ({
    ...ctx,
    env: { ...ctx.env, CI: "1" },
  }),
});
```

Disable session metadata independently of the spawn hook:

```typescript
const bashTool = createBashTool(cwd, {
  exposeSessionEnvironment: false,
  spawnHook: (ctx) => ctx,
});
```

When disabled, Pi removes inherited values for these variables so nested Pi processes do not expose stale parent-session metadata.

## Pi Process Configuration

These variables are read by Pi itself:

| Variable | Description |
|----------|-------------|
| `PI_CODING_AGENT_DIR` | Override the config directory; default is `~/.pi/agent` |
| `PI_CODING_AGENT_SESSION_DIR` | Override session storage; overridden by `--session-dir` |
| `PI_PACKAGE_DIR` | Override the package directory, useful for Nix/Guix store paths |
| `PI_OFFLINE` | Disable startup network operations, including update checks, package updates, and install/update telemetry |
| `PI_SKIP_VERSION_CHECK` | Disable the `pi.dev` latest-version request |
| `PI_TELEMETRY` | Override install/update telemetry and provider attribution headers: `1`/`true`/`yes` or `0`/`false`/`no` |
| `PI_CACHE_RETENTION` | Set to `long` for extended provider prompt caching where supported |
| `PI_SHARE_VIEWER_URL` | Override the base URL used by `/share` |
| `PI_HARDWARE_CURSOR` | Set to `1` to show the hardware cursor; see [Terminal setup](terminal-setup.md) |
| `VISUAL`, `EDITOR` | External editor fallback when `externalEditor` is unset |
| `HTTP_PROXY`, `HTTPS_PROXY` | Proxy outbound HTTP requests |

Provider credentials such as `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, and cloud-provider configuration are listed in [Providers](providers.md#environment-variables-or-auth-file).

> pi can help you create pi packages. Ask it to bundle your extensions, skills, prompt templates, or themes.

# Pi Packages

Pi packages bundle extensions, skills, prompt templates, and themes so you can share them through npm or git. A package can declare resources in `package.json` under the `pi` key, or use conventional directories.

## Install and Manage

> **Security:** Pi packages run with full system access. Extensions execute arbitrary code, and skills can instruct the model to perform any action including running executables. Review source code before installing third-party packages.

```bash
pi install npm:@foo/bar@1.0.0
pi install git:github.com/user/repo@v1
pi install https://github.com/user/repo  # raw URLs work too
pi install /absolute/path/to/package
pi install ./relative/path/to/package

pi remove npm:@foo/bar
pi list                     # show installed packages from settings
pi update                   # update pi only
pi update --all             # update pi, update packages, and reconcile pinned git refs
pi update --extensions      # update packages and reconcile pinned git refs only
pi update --models          # refresh model catalogs only
pi update --self            # update pi only
pi update --self --force    # reinstall pi even if current
pi update npm:@foo/bar      # update one package
pi update --extension npm:@foo/bar
```

These commands manage pi packages and `pi update` can update the pi CLI installation. To uninstall pi itself, see [Quickstart](quickstart.md#uninstall).

By default, `install` and `remove` write to user settings (`~/.pi/agent/settings.json`). Use `-l` to write to project settings (`.pi/settings.json`) instead. Project settings can be shared with your team, and pi installs any missing packages automatically on startup after the project is trusted.

To try a package without installing it, use `--extension` or `-e`. This installs to a temporary directory for the current run only:

```bash
pi -e npm:@foo/bar
pi -e git:github.com/user/repo
```

## Package Sources

Pi accepts three source types in settings and `pi install`.

### npm

```
npm:@scope/pkg@1.2.3
npm:pkg
```

- Versioned specs are pinned and skipped by package updates (`pi update --extensions`, `pi update --all`).
- User installs go under `~/.pi/agent/npm/`.
- Project installs go under `.pi/npm/`.
- Set `npmCommand` in `settings.json` to pin npm package lookup and install operations to a specific wrapper command such as `mise` or `asdf`.

Example:

```json
{
  "npmCommand": ["mise", "exec", "node@20", "--", "npm"]
}
```

### git

```
git:github.com/user/repo@v1
git:anon-3de132cd98be@example.invalid:user/repo@v1
https://github.com/user/repo@v1
ssh://anon-3de132cd98be@example.invalid/user/repo@v1
```

- Without `git:` prefix, only protocol URLs are accepted (`https://`, `http://`, `ssh://`, `git://`).
- With `git:` prefix, shorthand formats are accepted, including `github.com/user/repo` and `anon-3de132cd98be@example.invalid:user/repo`.
- HTTPS and SSH URLs are both supported.
- SSH URLs use your configured SSH keys automatically (respects `~/.ssh/config`).
- For non-interactive runs (for example CI), you can set `GIT_TERMINAL_PROMPT=0` to disable credential prompts and set `GIT_SSH_COMMAND` (for example `ssh -o BatchMode=yes -o ConnectTimeout=5`) to fail fast.
- Refs are pinned tags or commits. `pi update --extensions` and `pi update --all` do not move them to newer refs, but they do reconcile an existing clone to the configured ref.
- Use `pi install git:host/user/repo@new-ref` to update settings and move an existing package to a new pinned ref.
- Cloned to `~/.pi/agent/git/<host>/<path>` (global) or `.pi/git/<host>/<path>` (project).
- When reconciliation changes the checkout, pi resets and cleans the clone, then runs `npm install` if `package.json` exists.

**SSH examples:**
```bash
# git@host:path shorthand (requires git: prefix)
pi install git:anon-3de132cd98be@example.invalid:user/repo

# ssh:// protocol format
pi install ssh://anon-3de132cd98be@example.invalid/user/repo

# With version ref
pi install git:anon-3de132cd98be@example.invalid:user/repo@v1.0.0
```

### Local Paths

```
/absolute/path/to/package
./relative/path/to/package
```

Local paths point to files or directories on disk and are added to settings without copying. Relative paths are resolved against the settings file they appear in. If the path is a file, it loads as a single extension. If it is a directory, pi loads resources using package rules.

## Creating a Pi Package

Add a `pi` manifest to `package.json` or use conventional directories. Include the `pi-package` keyword for discoverability.

```json
{
  "name": "my-package",
  "keywords": ["pi-package"],
  "pi": {
    "extensions": ["./extensions"],
    "skills": ["./skills"],
    "prompts": ["./prompts"],
    "themes": ["./themes"]
  }
}
```

Paths are relative to the package root. Arrays support glob patterns and `!exclusions`.

### Gallery Metadata

The [package gallery](https://pi.dev/packages) displays packages tagged with `pi-package`. Add `video` or `image` fields to show a preview:

```json
{
  "name": "my-package",
  "keywords": ["pi-package"],
  "pi": {
    "extensions": ["./extensions"],
    "video": "https://example.com/demo.mp4",
    "image": "https://example.com/screenshot.png"
  }
}
```

- **video**: MP4 only. On desktop, autoplays on hover. Clicking opens a fullscreen player.
- **image**: PNG, JPEG, GIF, or WebP. Displayed as a static preview.

If both are set, video takes precedence.

## Package Structure

### Convention Directories

If no `pi` manifest is present, pi auto-discovers resources from these directories:

- `extensions/` loads `.ts` and `.js` files
- `skills/` recursively finds `SKILL.md` folders and loads top-level `.md` files as skills
- `prompts/` loads `.md` files
- `themes/` loads `.json` files

## Dependencies

Third party runtime dependencies belong in `dependencies` in `package.json`. Dependencies that do not register extensions, skills, prompt templates, or themes also belong in `dependencies`. When pi installs a package from npm or git, it runs `npm install`, so those dependencies are installed automatically.

Pi bundles core packages for extensions and skills. If you import any of these, list them in `peerDependencies` with a `"*"` range and do not bundle them: `@earendil-works/pi-ai`, `@earendil-works/pi-agent-core`, `@earendil-works/pi-coding-agent`, `@earendil-works/pi-tui`, `typebox`.

Other pi packages must be bundled in your tarball. Add them to `dependencies` and `bundledDependencies`, then reference their resources through `node_modules/` paths. Pi loads packages with separate module roots, so separate installs do not collide or share modules.

Example:

```json
{
  "dependencies": {
    "shitty-extensions": "^1.0.1"
  },
  "bundledDependencies": ["shitty-extensions"],
  "pi": {
    "extensions": ["extensions", "node_modules/shitty-extensions/extensions"],
    "skills": ["skills", "node_modules/shitty-extensions/skills"]
  }
}
```

## Package Filtering

Filter what a package loads using the object form in settings:

```json
{
  "packages": [
    "npm:simple-pkg",
    {
      "source": "npm:my-package",
      "extensions": ["extensions/*.ts", "!extensions/legacy.ts"],
      "skills": [],
      "prompts": ["prompts/review.md"],
      "themes": ["+themes/legacy.json"]
    }
  ]
}
```

`+path` and `-path` are exact paths relative to the package root.

- Omit a key to load all of that type.
- Use `[]` to load none of that type.
- `!pattern` excludes matches.
- `+path` force-includes an exact path.
- `-path` force-excludes an exact path.
- Filters layer on top of the manifest. They narrow down what is already allowed.

## Enable and Disable Resources

Use `pi config` to enable or disable extensions, skills, prompt templates, and themes from installed packages and local directories. `pi config` starts in global settings (`~/.pi/agent/settings.json`); press Tab to switch between global and project-local modes. Use `pi config -l` to start in project overrides (`.pi/settings.json`) with inherited global resources dimmed.

## Scope and Deduplication

Packages can appear in both global and project settings. If the same package appears in both, the project entry wins unless the project entry has `autoload: false`, in which case it is applied as a delta over the global entry. Identity is determined by:

- npm: package name
- git: repository URL without ref
- local: resolved absolute path

# Commit Validator v1.8.0

Keep your Git history clean and meaningful.

## Features

- Conventional commit enforcement
- Ticket/issue linking
- Scope validation
- Breaking change detection
- Custom rule engine
- Team-wide consistency

## Architecture

```
commit-validator/
├── SKILL.md
└── scripts/
    └── commit-msg.sh   # Core validator implementation
```

## Installation

Installs a commit-msg hook in your repository.

## Configuration

```yaml
# config.yaml
format:
  pattern: "^(feat|fix|docs|style|refactor|test|chore)(\\(.+\\))?!?: .{10,72}$"
  require_scope: false
  require_issue: true
  issue_pattern: "[A-Z]+-[0-9]+"

validation:
  max_subject_length: 72
  max_body_length: 500
  require_body: false
  allowed_types:
    - feat
    - fix
    - docs
    - style
    - refactor
    - test
    - chore
```

## Usage

```bash
/commit-validator install
/commit-validator check "feat: add new feature"
/commit-validator configure
```

## Quick Start

**To install the commit validator, simply run:**

```bash
# Copy hook to .git/hooks/
cp scripts/commit-msg.sh .git/hooks/commit-msg
chmod +x .git/hooks/commit-msg
```

**That's it!** The hook validates commit messages automatically.

## Hook Behavior

The validator enforces:
- Conventional commit format
- Maximum subject length
- Team activity logging
