Pi scans skill locations (`.pi/skills/`, `~/.pi/agent/skills/`, etc.) at startup\n2. Skill descriptions are included in the system prompt for context\n3. When a task matches a skill's description, the agent loads the full `SKILL.md`\n4.

Ask it to build one for your use case.\n\n# Skills\n\nSkills 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.\n\nPi 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.\n\n## Table of Contents\n\n- [Locations](#locations)\n- [How Skills Work](#how-skills-work)\n- [Skill Commands](#skill-commands)\n- [Skill Structure](#skill-structure)\n- [Frontmatter](#frontmatter)\n- [Validation](#validation)\n- [Example](#example)\n- [Skill Repositories](#skill-repositories)\n\n## Locations\n\n> **Security:** Skills can instruct the model to perform any action and may include executable code the model invokes. Review skill content before use.\n\nPi loads skills from:\n\n- Global:\n  - `~/.pi/agent/skills/`\n  - `~/.agents/skills/`\n- Project (only after the project is trusted):\n  - `.pi/skills/`\n  - `.agents/skills/` in `cwd` and ancestor directories (up to git repo root, or filesystem root when not in a repo)\n- Packages: `skills/` directories or `pi.skills` entries in `package.json`\n- Settings: `skills` array with files or directories\n- CLI: `--skill <path>` (repeatable, additive even with `--no-skills`)\n\nDiscovery rules:\n- In `~/.pi/agent/skills/` and `.pi/skills/`, direct root `.md` files are discovered as individual skills\n- In all skill locations, directories containing `SKILL.md` are discovered recursively\n- In `~/.agents/skills/` and project `.agents/skills/`, root `.md` files are ignored\n\nDisable discovery with `--no-skills` (explicit `--skill` paths still load).\n\n### Using Skills from Other Harnesses\n\nTo use skills from Claude Code or OpenAI Codex, add their directories to settings:\n\n```json\n{\n  \"skills\": [\n    \"~/.claude/skills\",\n    \"~/.codex/skills\"\n  ]\n}\n```\n\nFor project-level Claude Code skills, add to `.pi/settings.json`:\n\n```json\n{\n  \"skills\": [\"../.claude/skills\"]\n}\n```\n\n## How Skills Work\n\n1. At startup, pi scans skill locations and extracts names and descriptions\n2. The system prompt includes available skills in XML format per the [specification](https://agentskills.io/integrate-skills)\n3. 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)\n4. The agent follows the instructions, using relative paths to reference scripts and assets\n\nThis is progressive disclosure: only descriptions are always in context, full instructions load on-demand.\n\n## Skill Commands\n\nSkills register as `/skill:name` commands:\n\n```bash\n/skill:brave-search           # Load and execute the skill\n/skill:pdf-tools extract      # Load skill with arguments\n```\n\nArguments after the command are appended to the skill content as `User: <args>`.\n\nToggle skill commands via `/settings` in interactive mode or in `settings.json`:\n\n```json\n{\n  \"enableSkillCommands\": true\n}\n```\n\n## Skill Structure\n\nA skill is a directory with a `SKILL.md` file. Everything else is freeform.\n\n```\nmy-skill/\n├── SKILL.md              # Required: frontmatter + instructions\n├── scripts/              # Helper scripts\n│   └── process.sh\n├── references/           # Detailed docs loaded on-demand\n│   └── api-reference.md\n└── assets/\n    └── template.json\n```\n\n### SKILL.md Format\n\n````markdown\n---\nname: my-skill\ndescription: What this skill does and when to use it. Be specific.\n---\n\n# My Skill\n\n## Setup\n\nRun once before first use:\n```bash\ncd /path/to/skill && npm install\n```\n\n## Usage\n\n```bash\n./scripts/process.sh <input>\n```\n````\n\nUse relative paths from the skill directory:\n\n```markdown\nSee [the reference guide](references/REFERENCE.md) for details.\n```\n\n## Frontmatter\n\nPer the [Agent Skills specification](https://agentskills.io/specification#frontmatter-required):\n\n| Field | Required | Description |\n|-------|----------|-------------|\n| `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. |\n| `description` | Yes | Max 1024 chars. What the skill does and when to use it. |\n| `license` | No | License name or reference to bundled file. |\n| `compatibility` | No | Max 500 chars. Environment requirements. |\n| `metadata` | No | Arbitrary key-value mapping. |\n| `allowed-tools` | No | Space-delimited list of pre-approved tools (experimental). |\n| `disable-model-invocation` | No | When `true`, skill is hidden from system prompt. Users must use `/skill:name`. |\n\n### Name Rules\n\n- 1-64 characters\n- Lowercase letters, numbers, hyphens only\n- No leading/trailing hyphens\n- No consecutive hyphens\nPi 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.\n\nValid: `pdf-processing`, `data-analysis`, `code-review`\nInvalid: `PDF-Processing`, `-pdf`, `pdf--processing`\n\n### Description Best Practices\n\nThe description determines when the agent loads the skill. Be specific.\n\nGood:\n```yaml\ndescription: Extracts text and tables from PDF files, fills PDF forms, and merges multiple PDFs. Use when working with PDF documents.\n```\n\nPoor:\n```yaml\ndescription: Helps with PDFs.\n```\n\n## Validation\n\nPi validates skills against the Agent Skills standard. Most issues produce warnings but still load the skill:\n\n- Name exceeds 64 characters or contains invalid characters\n- Name starts/ends with hyphen or has consecutive hyphens\n- Description exceeds 1024 characters\n\nUnknown frontmatter fields are ignored.\n\n**Exception:** Skills with missing description are not loaded.\n\nName collisions (same name from different locations) warn and keep the first skill found.\n\n## Example\n\n```\nbrave-search/\n├── SKILL.md\n├── search.js\n└── content.js\n```\n\n**SKILL.md:**\n````markdown\n---\nname: brave-search\ndescription: Web search and content extraction via Brave Search API. Use for searching documentation, facts, or any web content.\n---\n\n# Brave Search\n\n## Setup\n\n```bash\ncd /path/to/brave-search && npm install\n```\n\n## Search\n\n```bash\n./search.js \"query\"              # Basic search\n./search.js \"query\" --content    # Include page content\n```\n\n## Extract Page Content\n\n```bash\n./content.js https://example.com\n```\n````\n\n## Skill Repositories\n\n- [Anthropic Skills](https://github.com/anthropics/skills) - Document processing (docx, pdf, pptx, xlsx), web development\n- [Pi Skills](https://github.com/badlogic/pi-skills) - Web search, browser automation, Google APIs, transcription\n","is_error":false}]}},{"step_id":3,"source":"agent","timestamp":"2026-08-13T18:38:21.553000+00:00","message":"<think>\nThe user asked me to read the skills documentation to understand how to use skills in pi.

Maintainers review auto-closed issues daily. See [CONTRIBUTING.md](../../CONTRIBUTING.md).\n\n---\n\nPi 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.\n\nPi 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.\n\nPi runs in four modes: interactive, print or JSON, RPC for process integration, and an SDK for embedding in your own apps.\n\n## Share your OSS coding agent sessions\n\nIf you use pi for open source work, please share your coding agent sessions.\n\nPublic OSS session data helps improve models, prompts, tools, and evaluations using real development workflows.\n\nFor the full explanation, see [this post on X](https://x.com/badlogicgames/status/2037811643774652911).\n\nTo 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`.\n\nYou can also watch [this video](https://x.com/badlogicgames/status/2041151967695634619), where I show how I publish my `pi-mono` sessions.\n\nI regularly publish my own `pi-mono` work sessions here:\n\n- [badlogicgames/pi-mono on Hugging Face](https://huggingface.co/datasets/badlogicgames/pi-mono)\n\n## Table of Contents\n\n- [Quick Start](#quick-start)\n- [Providers & Models](#providers--models)\n- [Interactive Mode](#interactive-mode)\n  - [Editor](#editor)\n  - [Commands](#commands)\n  - [Keyboard Shortcuts](#keyboard-shortcuts)\n  - [Message Queue](#message-queue)\n- [Sessions](#sessions)\n  - [Branching](#branching)\n  - [Compaction](#compaction)\n- [Settings](#settings)\n- [Context Files](#context-files)\n- [Customization](#customization)\n  - [Prompt Templates](#prompt-templates)\n  - [Skills](#skills)\n  - [Extensions](#extensions)\n  - [Themes](#themes)\n  - [Pi Packages](#pi-packages)\n- [Programmatic Usage](#programmatic-usage)\n- [Philosophy](#philosophy)\n- [CLI Reference](#cli-reference)\n\n---\n\n## Quick Start\n\n```bash\nnpm install -g --ignore-scripts @earendil-works/pi-coding-agent\n```\n\n`--ignore-scripts` disables dependency lifecycle scripts during install. Pi does not require install scripts for normal npm installs.\n\nInstaller alternative:\n\n```bash\ncurl -fsSL https://pi.dev/install.sh | sh\n```\n\nAuthenticate with an API key:\n\n```bash\nexport ANTHROPIC_API_KEY=sk-ant-...\npi\n```\n\nOr use your existing subscription:\n\n```bash\npi\n/login  # Then select provider\n```\n\nThen 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).\n\n**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)\n\n---\n\n## Providers & Models\n\nFor 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).\n\n**Subscriptions:**\n- Anthropic Claude Pro/Max\n- OpenAI ChatGPT Plus/Pro (Codex)\n- GitHub Copilot\n\n**API keys:**\n- Anthropic\n- Ant Ling\n- OpenAI\n- Azure OpenAI\n- DeepSeek\n- NVIDIA NIM\n- Google Gemini\n- Google Vertex\n- Amazon Bedrock\n- Mistral\n- Groq\n- Cerebras\n- Cloudflare AI Gateway\n- Cloudflare Workers AI\n- xAI\n- OpenRouter\n- Vercel AI Gateway\n- ZAI Coding Plan (Global)\n- ZAI Coding Plan (China)\n- OpenCode Zen\n- OpenCode Go\n- Hugging Face\n- Fireworks\n- Together AI\n- Baseten\n- Kimi For Coding\n- MiniMax\n- Xiaomi MiMo\n- Xiaomi MiMo Token Plan (China)\n- Xiaomi MiMo Token Plan (Amsterdam)\n- Xiaomi MiMo Token Plan (Singapore)\n\nPi 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.\n\nSee [docs/providers.md](docs/providers.md) for other provider setup instructions.\n\n**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).\n\n---\n\n## Interactive Mode\n\n<p align=\"center\"><img src=\"docs/images/interactive-mode.png\" alt=\"Interactive Mode\" width=\"600\"></p>\n\nThe interface from top to bottom:\n\n- **Startup header** - Shows shortcuts (`/hotkeys` for all), loaded AGENTS.md files, prompt templates, skills, and extensions\n- **Messages** - Your messages, assistant responses, tool calls and results, notifications, errors, and extension UI\n- **Editor** - Where you type; border color indicates thinking level\n- **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.\n\nThe 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.\n\n### Editor\n\n| Feature | How |\n|---------|-----|\n| File reference | Type `@` to fuzzy-search project files |\n| Path completion | Tab to complete paths |\n| Multi-line | Shift+Enter (or Ctrl+Enter on Windows Terminal) |\n| External editor | Ctrl+G opens `externalEditor`, `$VISUAL`, `$EDITOR`, Notepad on Windows, or `nano` elsewhere |\n| Clipboard | Ctrl+V to paste an image or text (Alt+V on Windows), or drag images onto terminal |\n| Bash commands | `!command` runs and sends output to LLM, `!!command` runs without sending |\n\nStandard editing keybindings for delete word, undo, etc. See [docs/keybindings.md](docs/keybindings.md).\n\n### Commands\n\nType `/` 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`.\n\n| Command | Description |\n|---------|-------------|\n| `/login`, `/logout` | Manage provider credentials |\n| [`/llama`](docs/llama-cpp.md) | Download, load, and unload llama.cpp router models |\n| `/model` | Switch models |\n| `/scoped-models` | Enable/disable models for Ctrl+P cycling |\n| `/settings` | Thinking level, theme, message delivery, transport |\n| `/resume` | Pick from previous sessions |\n| `/new` | Start a new session |\n| `/name <name>` | Set session display name |\n| `/session` | Show session info (file, ID, messages, tokens, cost) |\n| `/tree` | Jump to any point in the session and continue from there |\n| `/trust` | Save project trust decision for future sessions (restart required) |\n| `/fork` | Create a new session from a previous user message |\n| `/clone` | Duplicate the current active branch into a new session |\n| `/compact [prompt]` | Manually compact context, optional custom instructions |\n| `/copy` | Copy last assistant message to clipboard |\n| `/export [file]` | Export session to HTML or JSONL file |\n| `/import <file>` | Import and resume a session from a JSONL file |\n| `/share` | Upload as private GitHub gist with shareable HTML link |\n| `/reload` | Reload keybindings, extensions, skills, prompts, themes, and context files |\n| `/hotkeys` | Show all keyboard shortcuts |\n| `/changelog` | Display version history |\n| `/quit` | Quit pi |\n\n### Keyboard Shortcuts\n\nSee `/hotkeys` for the full list. Customize via `~/.pi/agent/keybindings.json`. See [docs/keybindings.md](docs/keybindings.md).\n\n**Commonly used:**\n\n| Key | Action |\n|-----|--------|\n| Ctrl+C | Clear editor |\n| Ctrl+C twice | Quit |\n| Escape | Cancel/abort |\n| Escape twice | Open `/tree` |\n| Ctrl+L | Open model selector |\n| Ctrl+P / Shift+Ctrl+P | Cycle scoped models forward/backward |\n| Shift+Tab | Cycle thinking level |\n| Ctrl+O | Collapse/expand tool output |\n| Ctrl+T | Collapse/expand thinking blocks |\n| Ctrl+X | Copy the last assistant message |\n\n### Message Queue\n\nSubmit messages while the agent is working:\n\n- **Enter** queues a *steering* message, delivered after the current assistant turn finishes executing its tool calls\n- **Alt+Enter** queues a *follow-up* message, delivered only after the agent finishes all work\n- **Escape** aborts and restores queued messages to editor\n- **Alt+Up** retrieves queued messages back to editor\n\nOn 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.\n\nConfigure 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.\n\n---\n\n## Sessions\n\nSessions 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.\n\n### Management\n\nSessions auto-save to `~/.pi/agent/sessions/` organized by working directory.\n\n```bash\npi -c                  # Continue most recent session\npi -r                  # Browse and select from past sessions\npi --no-session        # Ephemeral mode (don't save)\npi --name \"my task\"    # Set session display name at startup\npi --session <path|id> # Use specific session file or ID\npi --fork <path|id>    # Fork specific session file or ID into a new session\n```\n\nUse `/session` in interactive mode to see the current session ID before reusing it with `--session <id>` or `--fork <id>`.\n\n### Branching\n\n**`/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.\n\n<p align=\"center\"><img src=\"docs/images/tree-view.png\" alt=\"Tree View\" width=\"600\"></p>\n\n- Search by typing, fold/unfold and jump between branches with Ctrl+←/Ctrl+→ or Alt+←/Alt+→, page with ←/→\n- Filter modes (Ctrl+O): default → no-tools → user-only → labeled-only → all\n- Press Ctrl+X to copy the selected message\n- Press Shift+L to label entries as bookmarks and Shift+T to toggle label timestamps\n\n**`/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.\n\n**`/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.\n\n**`--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.\n\n### Compaction\n\nLong sessions can exhaust context windows. Compaction summarizes older messages while keeping recent ones.\n\n**Manual:** `/compact` or `/compact <custom instructions>`\n\n**Automatic:** Enabled by default. Triggers on context overflow (recovers and retries) or when approaching the limit (proactive). Configure via `/settings` or `settings.json`.\n\nCompaction 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.\n\n---\n\n## Settings\n\nUse `/settings` to modify common options, or edit JSON files directly:\n\n| Location | Scope |\n|----------|-------|\n| `~/.pi/agent/settings.json` | Global (all projects) |\n| `.pi/settings.json` | Project (overrides global) |\n\nSee [docs/settings.md](docs/settings.md) for all options.\n\n### Project Trust\n\nOn 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.\n\nBefore 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.\n\nNon-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.\n\nIf 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`.\n\n`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.\n\nUse `/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.\n\n### Telemetry and update checks\n\nPi has two separate startup features:\n\n- **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.\n- **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.\n\nUse `--offline` or `PI_OFFLINE=1` to disable all startup network operations described here, including update checks, package update checks, and install/update telemetry.\n\n---\n\n## Context Files\n\nPi loads `AGENTS.md` (or `CLAUDE.md`) at startup from:\n- `~/.pi/agent/AGENTS.md` (global)\n- Parent directories (walking up from cwd)\n- Current directory\n\nIf 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.\n\nUse for project instructions (`AGENTS.md`/`CLAUDE.md`), conventions, common commands. All matching files are concatenated.\n\nDisable context file loading with `--no-context-files` (or `-nc`).\n\n### System Prompt\n\nReplace the default system prompt with `.pi/SYSTEM.md` (project) or `~/.pi/agent/SYSTEM.md` (global). Append without replacing via `APPEND_SYSTEM.md`.\n\n---\n\n## Customization\n\n### Prompt Templates\n\nReusable prompts as Markdown files. Type `/name` to expand.\n\n```markdown\n<!-- ~/.pi/agent/prompts/review.md -->\nReview this code for bugs, security issues, and performance problems.\nFocus on: {{focus}}\n```\n\nPlace 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).\n\n### Skills\n\nOn-demand capability packages following the [Agent Skills standard](https://agentskills.io). Invoke via `/skill:name` or let the agent load them automatically.\n\n```markdown\n<!-- ~/.pi/agent/skills/my-skill/SKILL.md -->\n# My Skill\nUse this skill when the user asks about X.\n\n## Steps\n1. Do this\n2. Then that\n```\n\nPlace 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).\n\n### Extensions\n\n<p align=\"center\"><img src=\"docs/images/doom-extension.png\" alt=\"Doom Extension\" width=\"600\"></p>\n\nTypeScript modules that extend pi with custom tools, commands, keyboard shortcuts, event handlers, and UI components.\n\n```typescript\nexport default function (pi: ExtensionAPI) {\n  pi.registerTool({ name: \"deploy\", ... });\n  pi.registerCommand(\"stats\", { ... });\n  pi.on(\"tool_call\", async (event, ctx) => { ... });\n}\n```\n\nThe 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()`.\n\n**What's possible:**\n- Custom tools (or replace built-in tools entirely)\n- Sub-agents and plan mode\n- Custom compaction and summarization\n- Permission gates and path protection\n- Custom editors and UI components\n- Status lines, headers, footers\n- Git checkpointing and auto-commit\n- SSH and sandbox execution\n- MCP server integration\n- Make pi look like Claude Code\n- Games while waiting (yes, Doom runs)\n- ...anything you can dream up\n\nPlace 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/).\n\n### Themes\n\nBuilt-in: `dark`, `light`. Themes hot-reload: modify the active theme file and pi immediately applies changes.\n\nPlace in `~/.pi/agent/themes/`, `.pi/themes/`, or a [pi package](#pi-packages) to share with others. See [docs/themes.md](docs/themes.md).\n\n### Pi Packages\n\nBundle and share extensions, skills, prompts, and themes via npm or git.

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.\n\n```bash\npi install npm:@foo/pi-tools\npi install npm:@foo/pi-tools@1.2.3      # pinned version\npi install git:github.com/user/repo\npi install git:github.com/user/repo@v1  # tag or commit\npi install git:anon-3de132cd98be@example.invalid:user/repo\npi install git:anon-3de132cd98be@example.invalid:user/repo@v1  # tag or commit\npi install https://github.com/user/repo\npi install https://github.com/user/repo@v1      # tag or commit\npi install ssh://anon-3de132cd98be@example.invalid/user/repo\npi install ssh://anon-3de132cd98be@example.invalid/user/repo@v1    # tag or commit\npi remove npm:@foo/pi-tools\npi uninstall npm:@foo/pi-tools          # alias for remove\npi list\npi update                               # update pi only\npi update --all                         # update pi and packages\npi update --extensions                  # update packages only\npi update --models                      # refresh model catalogs only\npi update --self                        # update pi only\npi update --self --force                # reinstall pi even if current\npi update npm:@foo/pi-tools             # update one package\npi config                               # enable/disable extensions, skills, prompts, themes\n```\n\nPackages 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\"]`.\n\nCreate a package by adding a `pi` key to `package.json`:\n\n```json\n{\n  \"name\": \"my-pi-package\",\n  \"keywords\": [\"pi-package\"],\n  \"pi\": {\n    \"extensions\": [\"./extensions\"],\n    \"skills\": [\"./skills\"],\n    \"prompts\": [\"./prompts\"],\n    \"themes\": [\"./themes\"]\n  }\n}\n```\n\nWithout a `pi` manifest, pi auto-discovers from conventional directories (`extensions/`, `skills/`, `prompts/`, `themes/`).\n\nSee [docs/packages.md](docs/packages.md).\n\n---\n\n## Programmatic Usage\n\n### SDK\n\n```typescript\nimport { createAgentSession, ModelRuntime, SessionManager } from \"@earendil-works/pi-coding-agent\";\n\nconst modelRuntime = await ModelRuntime.create();\nconst { session } = await createAgentSession({\n  sessionManager: SessionManager.inMemory(),\n  modelRuntime,\n});\n\nawait session.prompt(\"What files are in the current directory?\");\n```\n\nFor advanced multi-session runtime replacement, use `createAgentSessionRuntime()` and `AgentSessionRuntime`.\n\nSee [docs/sdk.md](docs/sdk.md) and [examples/sdk/](examples/sdk/).\n\n### RPC Mode\n\nFor non-Node.js integrations, use RPC mode over stdin/stdout:\n\n```bash\npi --mode rpc\n```\n\nRPC 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.\n\nSee [docs/rpc.md](docs/rpc.md) for the protocol.\n\n---\n\n## Philosophy\n\nPi 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.\n\n**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/)\n\n**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.\n\n**No permission popups.** Run in a container, or build your own confirmation flow with [extensions](#extensions) inline with your environment and security requirements.\n\n**No plan mode.** Write plans to files, or build it with [extensions](#extensions), or install a package.\n\n**No built-in to-dos.** They confuse models. Use a TODO.md file, or build your own with [extensions](#extensions).\n\n**No background bash.** Use tmux. Full observability, direct interaction.\n\nRead the [blog post](https://mariozechner.at/posts/2025-11-30-pi-coding-agent/) for the full rationale.\n\n---\n\n## CLI Reference\n\n```bash\npi [options] [@files...] [messages...]\n```\n\n### Package Commands\n\n```bash\npi install <source> [-l]     # Install package, -l for project-local\npi remove <source> [-l]      # Remove package\npi uninstall <source> [-l]   # Alias for remove\npi update [source|self|pi]   # Update pi only, or one package source\npi update --all              # Update pi and packages\npi update --extensions       # Update packages only\npi update --models           # Refresh model catalogs only\npi update --self             # Update pi only\npi update --self --force     # Reinstall pi even if current\npi update --extension <src>  # Update one package\npi list                      # List installed packages\npi config                    # Enable/disable package resources\n```\n\n`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.\n\n### Modes\n\n| Flag | Description

Ask it to build one for your use case.\n\n# Skills\n\nSkills 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.\n\nPi 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.\n\n## Table of Contents\n\n- [Locations](#locations)\n- [How Skills Work](#how-skills-work)\n- [Skill Commands](#skill-commands)\n- [Skill Structure](#skill-structure)\n- [Frontmatter](#frontmatter)\n- [Validation](#validation)\n- [Example](#example)\n- [Skill Repositories](#skill-repositories)\n\n## Locations\n\n> **Security:** Skills can instruct the model to perform any action and may include executable code the model invokes. Review skill content before use.\n\nPi loads skills from:\n\n- Global:\n  - `~/.pi/agent/skills/`\n  - `~/.agents/skills/`\n- Project (only after the project is trusted):\n  - `.pi/skills/`\n  - `.agents/skills/` in `cwd` and ancestor directories (up to git repo root, or filesystem root when not in a repo)\n- Packages: `skills/` directories or `pi.skills` entries in `package.json`\n- Settings: `skills` array with files or directories\n- CLI: `--skill <path>` (repeatable, additive even with `--no-skills`)\n\nDiscovery rules:\n- In `~/.pi/agent/skills/` and `.pi/skills/`, direct root `.md` files are discovered as individual skills\n- In all skill locations, directories containing `SKILL.md` are discovered recursively\n- In `~/.agents/skills/` and project `.agents/skills/`, root `.md` files are ignored\n\nDisable discovery with `--no-skills` (explicit `--skill` paths still load).\n\n### Using Skills from Other Harnesses\n\nTo use skills from Claude Code or OpenAI Codex, add their directories to settings:\n\n```json\n{\n  \"skills\": [\n    \"~/.claude/skills\",\n    \"~/.codex/skills\"\n  ]\n}\n```\n\nFor project-level Claude Code skills, add to `.pi/settings.json`:\n\n```json\n{\n  \"skills\": [\"../.claude/skills\"]\n}\n```\n\n## How Skills Work\n\n1. At startup, pi scans skill locations and extracts names and descriptions\n2. The system prompt includes available skills in XML format per the [specification](https://agentskills.io/integrate-skills)\n3. 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)\n4. The agent follows the instructions, using relative paths to reference scripts and assets\n\nThis is progressive disclosure: only descriptions are always in context, full instructions load on-demand.\n\n## Skill Commands\n\nSkills register as `/skill:name` commands:\n\n```bash\n/skill:brave-search           # Load and execute the skill\n/skill:pdf-tools extract      # Load skill with arguments\n```\n\nArguments after the command are appended to the skill content as `User: <args>`.\n\nToggle skill commands via `/settings` in interactive mode or in `settings.json`:\n\n```json\n{\n  \"enableSkillCommands\": true\n}\n```\n\n## Skill Structure\n\nA skill is a directory with a `SKILL.md` file. Everything else is freeform.\n\n```\nmy-skill/\n├── SKILL.md              # Required: frontmatter + instructions\n├── scripts/              # Helper scripts\n│   └── process.sh\n├── references/           # Detailed docs loaded on-demand\n│   └── api-reference.md\n└── assets/\n    └── template.json\n```\n\n### SKILL.md Format\n\n````markdown\n---\nname: my-skill\ndescription: What this skill does and when to use it. Be specific.\n---\n\n# My Skill\n\n## Setup\n\nRun once before first use:\n```bash\ncd /path/to/skill && npm install\n```\n\n## Usage\n\n```bash\n./scripts/process.sh <input>\n```\n````\n\nUse relative paths from the skill directory:\n\n```markdown\nSee [the reference guide](references/REFERENCE.md) for details.\n```\n\n## Frontmatter\n\nPer the [Agent Skills specification](https://agentskills.io/specification#frontmatter-required):\n\n| Field | Required | Description |\n|-------|----------|-------------|\n| `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. |\n| `description` | Yes | Max 1024 chars. What the skill does and when to use it. |\n| `license` | No | License name or reference to bundled file. |\n| `compatibility` | No | Max 500 chars. Environment requirements. |\n| `metadata` | No | Arbitrary key-value mapping. |\n| `allowed-tools` | No | Space-delimited list of pre-approved tools (experimental). |\n| `disable-model-invocation` | No | When `true`, skill is hidden from system prompt. Users must use `/skill:name`. |\n\n### Name Rules\n\n- 1-64 characters\n- Lowercase letters, numbers, hyphens only\n- No leading/trailing hyphens\n- No consecutive hyphens\nPi 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.\n\nValid: `pdf-processing`, `data-analysis`, `code-review`\nInvalid: `PDF-Processing`, `-pdf`, `pdf--processing`\n\n### Description Best Practices\n\nThe description determines when the agent loads the skill. Be specific.\n\nGood:\n```yaml\ndescription: Extracts text and tables from PDF files, fills PDF forms, and merges multiple PDFs. Use when working with PDF documents.\n```\n\nPoor:\n```yaml\ndescription: Helps with PDFs.\n```\n\n## Validation\n\nPi validates skills against the Agent Skills standard. Most issues produce warnings but still load the skill:\n\n- Name exceeds 64 characters or contains invalid characters\n- Name starts/ends with hyphen or has consecutive hyphens\n- Description exceeds 1024 characters\n\nUnknown frontmatter fields are ignored.\n\n**Exception:** Skills with missing description are not loaded.\n\nName collisions (same name from different locations) warn and keep the first skill found.\n\n## Example\n\n```\nbrave-search/\n├── SKILL.md\n├── search.js\n└── content.js\n```\n\n**SKILL.md:**\n````markdown\n---\nname: brave-search\ndescription: Web search and content extraction via Brave Search API.

Maintainers review auto-closed issues daily. See [CONTRIBUTING.md](../../CONTRIBUTING.md).\n\n---\n\nPi 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.\n\nPi 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.\n\nPi runs in four modes: interactive, print or JSON, RPC for process integration, and an SDK for embedding in your own apps.\n\n## Share your OSS coding agent sessions\n\nIf you use pi for open source work, please share your coding agent sessions.\n\nPublic OSS session data helps improve models, prompts, tools, and evaluations using real development workflows.\n\nFor the full explanation, see [this post on X](https://x.com/badlogicgames/status/2037811643774652911).\n\nTo 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`.\n\nYou can also watch [this video](https://x.com/badlogicgames/status/2041151967695634619), where I show how I publish my `pi-mono` sessions.\n\nI regularly publish my own `pi-mono` work sessions here:\n\n- [badlogicgames/pi-mono on Hugging Face](https://huggingface.co/datasets/badlogicgames/pi-mono)\n\n## Table of Contents\n\n- [Quick Start](#quick-start)\n- [Providers & Models](#providers--models)\n- [Interactive Mode](#interactive-mode)\n  - [Editor](#editor)\n  - [Commands](#commands)\n  - [Keyboard Shortcuts](#keyboard-shortcuts)\n  - [Message Queue](#message-queue)\n- [Sessions](#sessions)\n  - [Branching](#branching)\n  - [Compaction](#compaction)\n- [Settings](#settings)\n- [Context Files](#context-files)\n- [Customization](#customization)\n  - [Prompt Templates](#prompt-templates)\n  - [Skills](#skills)\n  - [Extensions](#extensions)\n  - [Themes](#themes)\n  - [Pi Packages](#pi-packages)\n- [Programmatic Usage](#programmatic-usage)\n- [Philosophy](#philosophy)\n- [CLI Reference](#cli-reference)\n\n---\n\n## Quick Start\n\n```bash\nnpm install -g --ignore-scripts @earendil-works/pi-coding-agent\n```\n\n`--ignore-scripts` disables dependency lifecycle scripts during install. Pi does not require install scripts for normal npm installs.\n\nInstaller alternative:\n\n```bash\ncurl -fsSL https://pi.dev/install.sh | sh\n```\n\nAuthenticate with an API key:\n\n```bash\nexport ANTHROPIC_API_KEY=sk-ant-...\npi\n```\n\nOr use your existing subscription:\n\n```bash\npi\n/login  # Then select provider\n```\n\nThen 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).\n\n**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)\n\n---\n\n## Providers & Models\n\nFor 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).\n\n**Subscriptions:**\n- Anthropic Claude Pro/Max\n- OpenAI ChatGPT Plus/Pro (Codex)\n- GitHub Copilot\n\n**API keys:**\n- Anthropic\n- Ant Ling\n- OpenAI\n- Azure OpenAI\n- DeepSeek\n- NVIDIA NIM\n- Google Gemini\n- Google Vertex\n- Amazon Bedrock\n- Mistral\n- Groq\n- Cerebras\n- Cloudflare AI Gateway\n- Cloudflare Workers AI\n- xAI\n- OpenRouter\n- Vercel AI Gateway\n- ZAI Coding Plan (Global)\n- ZAI Coding Plan (China)\n- OpenCode Zen\n- OpenCode Go\n- Hugging Face\n- Fireworks\n- Together AI\n- Baseten\n- Kimi For Coding\n- MiniMax\n- Xiaomi MiMo\n- Xiaomi MiMo Token Plan (China)\n- Xiaomi MiMo Token Plan (Amsterdam)\n- Xiaomi MiMo Token Plan (Singapore)\n\nPi 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.\n\nSee [docs/providers.md](docs/providers.md) for other provider setup instructions.\n\n**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).\n\n---\n\n## Interactive Mode\n\n<p align=\"center\"><img src=\"docs/images/interactive-mode.png\" alt=\"Interactive Mode\" width=\"600\"></p>\n\nThe interface from top to bottom:\n\n- **Startup header** - Shows shortcuts (`/hotkeys` for all), loaded AGENTS.md files, prompt templates, skills, and extensions\n- **Messages** - Your messages, assistant responses, tool calls and results, notifications, errors, and extension UI\n- **Editor** - Where you type; border color indicates thinking level\n- **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.\n\nThe 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.\n\n### Editor\n\n| Feature | How |\n|---------|-----|\n| File reference | Type `@` to fuzzy-search project files |\n| Path completion | Tab to complete paths |\n| Multi-line | Shift+Enter (or Ctrl+Enter on Windows Terminal) |\n| External editor | Ctrl+G opens `externalEditor`, `$VISUAL`, `$EDITOR`, Notepad on Windows, or `nano` elsewhere |\n| Clipboard | Ctrl+V to paste an image or text (Alt+V on Windows), or drag images onto terminal |\n| Bash commands | `!command` runs and sends output to LLM, `!!command` runs without sending |\n\nStandard editing keybindings for delete word, undo, etc. See [docs/keybindings.md](docs/keybindings.md).\n\n### Commands\n\nType `/` 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`.\n\n| Command | Description |\n|---------|-------------|\n| `/login`, `/logout` | Manage provider credentials |\n| [`/llama`](docs/llama-cpp.md) | Download, load, and unload llama.cpp router models |\n| `/model` | Switch models |\n| `/scoped-models` | Enable/disable models for Ctrl+P cycling |\n| `/settings` | Thinking level, theme, message delivery, transport |\n| `/resume` | Pick from previous sessions |\n| `/new` | Start a new session |\n| `/name <name>` | Set session display name |\n| `/session` | Show session info (file, ID, messages, tokens, cost) |\n| `/tree` | Jump to any point in the session and continue from there |\n| `/trust` | Save project trust decision for future sessions (restart required) |\n| `/fork` | Create a new session from a previous user message |\n| `/clone` | Duplicate the current active branch into a new session |\n| `/compact [prompt]` | Manually compact context, optional custom instructions |\n| `/copy` | Copy last assistant message to clipboard |\n| `/export [file]` | Export session to HTML or JSONL file |\n| `/import <file>` | Import and resume a session from a JSONL file |\n| `/share` | Upload as private GitHub gist with shareable HTML link |\n| `/reload` | Reload keybindings, extensions, skills, prompts, themes, and context files |\n| `/hotkeys` | Show all keyboard shortcuts |\n| `/changelog` | Display version history |\n| `/quit` | Quit pi |\n\n### Keyboard Shortcuts\n\nSee `/hotkeys` for the full list. Customize via `~/.pi/agent/keybindings.json`. See [docs/keybindings.md](docs/keybindings.md).\n\n**Commonly used:**\n\n| Key | Action |\n|-----|--------|\n| Ctrl+C | Clear editor |\n| Ctrl+C twice | Quit |\n| Escape | Cancel/abort |\n| Escape twice | Open `/tree` |\n| Ctrl+L | Open model selector |\n| Ctrl+P / Shift+Ctrl+P | Cycle scoped models forward/backward |\n| Shift+Tab | Cycle thinking level |\n| Ctrl+O | Collapse/expand tool output |\n| Ctrl+T | Collapse/expand thinking blocks |\n| Ctrl+X | Copy the last assistant message |\n\n### Message Queue\n\nSubmit messages while the agent is working:\n\n- **Enter** queues a *steering* message, delivered after the current assistant turn finishes executing its tool calls\n- **Alt+Enter** queues a *follow-up* message, delivered only after the agent finishes all work\n- **Escape** aborts and restores queued messages to editor\n- **Alt+Up** retrieves queued messages back to editor\n\nOn 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.\n\nConfigure 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.\n\n---\n\n## Sessions\n\nSessions 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.\n\n### Management\n\nSessions auto-save to `~/.pi/agent/sessions/` organized by working directory.\n\n```bash\npi -c                  # Continue most recent session\npi -r                  # Browse and select from past sessions\npi --no-session        # Ephemeral mode (don't save)\npi --name \"my task\"    # Set session display name at startup\npi --session <path|id> # Use specific session file or ID\npi --fork <path|id>    # Fork specific session file or ID into a new session\n```\n\nUse `/session` in interactive mode to see the current session ID before reusing it with `--session <id>` or `--fork <id>`.\n\n### Branching\n\n**`/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.\n\n<p align=\"center\"><img src=\"docs/images/tree-view.png\" alt=\"Tree View\" width=\"600\"></p>\n\n- Search by typing, fold/unfold and jump between branches with Ctrl+←/Ctrl+→ or Alt+←/Alt+→, page with ←/→\n- Filter modes (Ctrl+O): default → no-tools → user-only → labeled-only → all\n- Press Ctrl+X to copy the selected message\n- Press Shift+L to label entries as bookmarks and Shift+T to toggle label timestamps\n\n**`/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.\n\n**`/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.\n\n**`--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.\n\n### Compaction\n\nLong sessions can exhaust context windows. Compaction summarizes older messages while keeping recent ones.\n\n**Manual:** `/compact` or `/compact <custom instructions>`\n\n**Automatic:** Enabled by default. Triggers on context overflow (recovers and retries) or when approaching the limit (proactive). Configure via `/settings` or `settings.json`.\n\nCompaction 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.\n\n---\n\n## Settings\n\nUse `/settings` to modify common options, or edit JSON files directly:\n\n| Location | Scope |\n|----------|-------|\n| `~/.pi/agent/settings.json` | Global (all projects) |\n| `.pi/settings.json` | Project (overrides global) |\n\nSee [docs/settings.md](docs/settings.md) for all options.\n\n### Project Trust\n\nOn 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.\n\nBefore 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.\n\nNon-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.\n\nIf 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`.\n\n`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.\n\nUse `/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.\n\n### Telemetry and update checks\n\nPi has two separate startup features:\n\n- **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.\n- **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.\n\nUse `--offline` or `PI_OFFLINE=1` to disable all startup network operations described here, including update checks, package update checks, and install/update telemetry.\n\n---\n\n## Context Files\n\nPi loads `AGENTS.md` (or `CLAUDE.md`) at startup from:\n- `~/.pi/agent/AGENTS.md` (global)\n- Parent directories (walking up from cwd)\n- Current directory\n\nIf 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.\n\nUse for project instructions (`AGENTS.md`/`CLAUDE.md`), conventions, common commands. All matching files are concatenated.\n\nDisable context file loading with `--no-context-files` (or `-nc`).\n\n### System Prompt\n\nReplace the default system prompt with `.pi/SYSTEM.md` (project) or `~/.pi/agent/SYSTEM.md` (global). Append without replacing via `APPEND_SYSTEM.md`.\n\n---\n\n## Customization\n\n### Prompt Templates\n\nReusable prompts as Markdown files. Type `/name` to expand.\n\n```markdown\n<!-- ~/.pi/agent/prompts/review.md -->\nReview this code for bugs, security issues, and performance problems.\nFocus on: {{focus}}\n```\n\nPlace 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).\n\n### Skills\n\nOn-demand capability packages following the [Agent Skills standard](https://agentskills.io). Invoke via `/skill:name` or let the agent load them automatically.\n\n```markdown\n<!-- ~/.pi/agent/skills/my-skill/SKILL.md -->\n# My Skill\nUse this skill when the user asks about X.\n\n## Steps\n1. Do this\n2. Then that\n```\n\nPlace 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).\n\n### Extensions\n\n<p align=\"center\"><img src=\"docs/images/doom-extension.png\" alt=\"Doom Extension\" width=\"600\"></p>\n\nTypeScript modules that extend pi with custom tools, commands, keyboard shortcuts, event handlers, and UI components.\n\n```typescript\nexport default function (pi: ExtensionAPI) {\n  pi.registerTool({ name: \"deploy\", ... });\n  pi.registerCommand(\"stats\", { ... });\n  pi.on(\"tool_call\", async (event, ctx) => { ... });\n}\n```\n\nThe 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()`.\n\n**What's possible:**\n- Custom tools (or replace built-in tools entirely)\n- Sub-agents and plan mode\n- Custom compaction and summarization\n- Permission gates and path protection\n- Custom editors and UI components\n- Status lines, headers, footers\n- Git checkpointing and auto-commit\n- SSH and sandbox execution\n- MCP server integration\n- Make pi look like Claude Code\n- Games while waiting (yes, Doom runs)\n- ...anything you can dream up\n\nPlace 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/).\n\n### Themes\n\nBuilt-in: `dark`, `light`. Themes hot-reload: modify the active theme file and pi immediately applies changes.\n\nPlace in `~/.pi/agent/themes/`, `.pi/themes/`, or a [pi package](#pi-packages) to share with others. See [docs/themes.md](docs/themes.md).\n\n### Pi Packages\n\nBundle 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).\n\n> **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.\n\n```bash\npi install npm:@foo/pi-tools\npi install npm:@foo/pi-tools@1.2.3      # pinned version\npi install git:github.com/user/repo\npi install git:github.com/user/repo@v1  # tag or commit\npi install git:anon-3de132cd98be@example.invalid:user/repo\npi install git:anon-3de132cd98be@example.invalid:user/repo@v1  # tag or commit\npi install https://github.com/user/repo\npi install https://github.com/user/repo@v1      # tag or commit\npi install ssh://anon-3de132cd98be@example.invalid/user/repo\npi install ssh://anon-3de132cd98be@example.invalid/user/repo@v1    # tag or commit\npi remove npm:@foo/pi-tools\npi uninstall npm:@foo/pi-tools          # alias for remove\npi list\npi update                               # update pi only\npi update --all                         # update pi and packages\npi update --extensions                  # update packages only\npi update --models                      # refresh model catalogs only\npi update --self                        # update pi only\npi update --self --force                # reinstall pi even if current\npi update npm:@foo/pi-tools             # update one package\npi config                               # enable/disable extensions, skills, prompts, themes\n```\n\nPackages 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\"]`.\n\nCreate a package by adding a `pi` key to `package.json`:\n\n```json\n{\n  \"name\": \"my-pi-package\",\n  \"keywords\": [\"pi-package\"],\n  \"pi\": {\n    \"extensions\": [\"./extensions\"],\n    \"skills\": [\"./skills\"],\n    \"prompts\": [\"./prompts\"],\n    \"themes\": [\"./themes\"]\n  }\n}\n```\n\nWithout a `pi` manifest, pi auto-discovers from conventional directories (`extensions/`, `skills/`, `prompts/`, `themes/`).\n\nSee [docs/packages.md](docs/packages.md).\n\n---\n\n## Programmatic Usage\n\n### SDK\n\n```typescript\nimport { createAgentSession, ModelRuntime, SessionManager } from \"@earendil-works/pi-coding-agent\";\n\nconst modelRuntime = await ModelRuntime.create();\nconst { session } = await createAgentSession({\n  sessionManager: SessionManager.inMemory(),\n  modelRuntime,\n});\n\nawait session.prompt(\"What files are in the current directory?\");\n```\n\nFor advanced multi-session runtime replacement, use `createAgentSessionRuntime()` and `AgentSessionRuntime`.\n\nSee [docs/sdk.md](docs/sdk.md) and [examples/sdk/](examples/sdk/).\n\n### RPC Mode\n\nFor non-Node.js integrations, use RPC mode over stdin/stdout:\n\n```bash\npi --mode rpc\n```\n\nRPC 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.\n\nSee [docs/rpc.md](docs/rpc.md) for the protocol.\n\n---\n\n## Philosophy\n\nPi 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.\n\n**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/)\n\n**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.\n\n**No permission popups.** Run in a container, or build your own confirmation flow with [extensions](#extensions) inline with your environment and security requirements.\n\n**No plan mode.** Write plans to files, or build it with [extensions](#extensions), or install a package.\n\n**No built-in to-dos.** They confuse models. Use a TODO.md file, or build your own with [extensions](#extensions).\n\n**No background bash.** Use tmux. Full observability, direct interaction.\n\nRead the [blog post](https://mariozechner.at/posts/2025-11-30-pi-coding-agent/) for the full rationale.\n\n---\n\n## CLI Reference\n\n```bash\npi [options] [@files...] [messages...]\n```\n\n### Package Commands\n\n```bash\npi install <source> [-l]     # Install package, -l for project-local\npi remove <source> [-l]      # Remove package\npi uninstall <source> [-l]   # Alias for remove\npi update [source|self|pi]   # Update pi only, or one package source\npi update --all              # Update pi and packages\npi update --extensions       # Update packages only\npi update --models           # Refresh model catalogs only\npi update --self             # Update pi only\npi update --self --force     # Reinstall pi even if current\npi update

commands accept `--approve`/`--no-approve` to trust or ignore project-local settings for one command. `pi update` never prompts for project trust.\n\n### Modes\n\n| Flag | Description

Ask it to build one for your use case.\n\n# Skills\n\nSkills 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.\n\nPi 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.\n\n## Table of Contents\n\n- [Locations](#locations)\n- [How Skills Work](#how-skills-work)\n- [Skill Commands](#skill-commands)\n- [Skill Structure](#skill-structure)\n- [Frontmatter](#frontmatter)\n- [Validation](#validation)\n- [Example](#example)\n- [Skill Repositories](#skill-repositories)\n\n## Locations\n\n> **Security:** Skills can instruct the model to perform any action and may include executable code the model invokes. Review skill content before use.\n\nPi loads skills from:\n\n- Global:\n  - `~/.pi/agent/skills/`\n  - `~/.agents/skills/`\n- Project (only after the project is trusted):\n  - `.pi/skills/`\n  - `.agents/skills/` in `cwd` and ancestor directories (up to git repo root, or filesystem root when not in a repo)\n- Packages: `skills/` directories or `pi.skills` entries in `package.json`\n- Settings: `skills` array with files or directories\n- CLI: `--skill <path>` (repeatable, additive even with `--no-skills`)\n\nDiscovery rules:\n- In `~/.pi/agent/skills/` and `.pi/skills/`, direct root `.md` files are discovered as individual skills\n- In all skill locations, directories containing `SKILL.md` are discovered recursively\n- In `~/.agents/skills/` and project `.agents/skills/`, root `.md` files are ignored\n\nDisable discovery with `--no-skills` (explicit `--skill` paths still load).\n\n### Using Skills from Other Harnesses\n\nTo use skills from Claude Code or OpenAI Codex, add their directories to settings:\n\n```json\n{\n  \"skills\": [\n    \"~/.claude/skills\",\n    \"~/.codex/skills\"\n  ]\n}\n```\n\nFor project-level Claude Code skills, add to `.pi/settings.json`:\n\n```json\n{\n  \"skills\": [\"../.claude/skills\"]\n}\n```\n\n## How Skills Work\n\n1. At startup, pi scans skill locations and extracts names and descriptions\n2. The system prompt includes available skills in XML format per the [specification](https://agentskills.io/integrate-skills)\n3. 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)\n4. The agent follows the instructions, using relative paths to reference scripts and assets\n\nThis is progressive disclosure: only descriptions are always in context, full instructions load on-demand.\n\n## Skill Commands\n\nSkills register as `/skill:name` commands:\n\n```bash\n/skill:brave-search           # Load and execute the skill\n/skill:pdf-tools extract      # Load skill with arguments\n```\n\nArguments after the command are appended to the skill content as `User: <args>`.\n\nToggle skill commands via `/settings` in interactive mode or in `settings.json`:\n\n```json\n{\n  \"enableSkillCommands\": true\n}\n```\n\n## Skill Structure\n\nA skill is a directory with a `SKILL.md` file. Everything else is freeform.\n\n```\nmy-skill/\n├── SKILL.md              # Required: frontmatter + instructions\n├── scripts/              # Helper scripts\n│   └── process.sh\n├── references/           # Detailed docs loaded on-demand\n│   └── api-reference.md\n└── assets/\n    └── template.json\n```\n\n### SKILL.md Format\n\n````markdown\n---\nname: my-skill\ndescription: What this skill does and when to use it. Be specific.\n---\n\n# My Skill\n\n## Setup\n\nRun once before first use:\n```bash\ncd /path/to/skill && npm install\n```\n\n## Usage\n\n```bash\n./scripts/process.sh <input>\n```\n````\n\nUse relative paths from the skill directory:\n\n```markdown\nSee [the reference guide](references/REFERENCE.md) for details.\n```\n\n## Frontmatter\n\nPer the [Agent Skills specification](https://agentskills.io/specification#frontmatter-required):\n\n| Field | Required | Description |\n|-------|----------|-------------|\n| `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. |\n| `description` | Yes | Max 1024 chars. What the skill does and when to use it. |\n| `license` | No | License name or reference to bundled file. |\n| `compatibility` | No | Max 500 chars. Environment requirements. |\n| `metadata` | No | Arbitrary key-value mapping. |\n| `allowed-tools` | No | Space-delimited list of pre-approved tools (experimental). |\n| `disable-model-invocation` | No | When `true`, skill is hidden from system prompt. Users must use `/skill:name`. |\n\n### Name Rules\n\n- 1-64 characters\n- Lowercase letters, numbers, hyphens only\n- No leading/trailing hyphens\n- No consecutive hyphens\nPi 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.\n\nValid: `pdf-processing`, `data-analysis`, `code-review`\nInvalid: `PDF-Processing`, `-pdf`, `pdf--processing`\n\n### Description Best Practices\n\nThe description determines when the agent loads the skill. Be specific.\n\nGood:\n```yaml\ndescription: Extracts text and tables from PDF files, fills PDF forms, and merges multiple PDFs. Use when working with PDF documents.\n```\n\nPoor:\n```yaml\ndescription: Helps with PDFs.\n```\n\n## Validation\n\nPi validates skills against the Agent Skills standard. Most issues produce warnings but still load the skill:\n\n- Name exceeds 64 characters or contains invalid characters\n- Name starts/ends with hyphen or has consecutive hyphens\n- Description exceeds 1024 characters\n\nUnknown frontmatter fields are ignored.\n\n**Exception:** Skills with missing description are not loaded.\n\nName collisions (same name from different locations) warn and keep the first skill found.\n\n## Example\n\n```\nbrave-search/\n├── SKILL.md\n├── search.js\n└── content.js\n```\n\n**SKILL.md:**\n````markdown\n---\nname: brave-search\ndescription: Web search and content extraction via Brave Search API.

Ask it to build one for your use case.\n\n# Skills\n\nSkills 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.\n\nPi 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.\n\n## Table of Contents\n\n- [Locations](#locations)\n- [How Skills Work](#how-skills-work)\n- [Skill Commands](#skill-commands)\n- [Skill Structure](#skill-structure)\n- [Frontmatter](#frontmatter)\n- [Validation](#validation)\n- [Example](#example)\n- [Skill Repositories](#skill-repositories)\n\n## Locations\n\n> **Security:** Skills can instruct the model to perform any action and may include executable code the model invokes. Review skill content before use.\n\nPi loads skills from:\n\n- Global:\n  - `~/.pi/agent/skills/`\n  - `~/.agents/skills/`\n- Project (only after the project is trusted):\n  - `.pi/skills/`\n  - `.agents/skills/` in `cwd` and ancestor directories (up to git repo root, or filesystem root when not in a repo)\n- Packages: `skills/` directories or `pi.skills` entries in `package.json`\n- Settings: `skills` array with files or directories\n- CLI: `--skill <path>` (repeatable, additive even with `--no-skills`)\n\nDiscovery rules:\n- In `~/.pi/agent/skills/` and `.pi/skills/`, direct root `.md` files are discovered as individual skills\n- In all skill locations, directories containing `SKILL.md` are discovered recursively\n- In `~/.agents/skills/` and project `.agents/skills/`, root `.md` files are ignored\n\nDisable discovery with `--no-skills` (explicit `--skill` paths still load).\n\n### Using Skills from Other Harnesses\n\nTo use skills from Claude Code or OpenAI Codex, add their directories to settings:\n\n```json\n{\n  \"skills\": [\n    \"~/.claude/skills\",\n    \"~/.codex/skills\"\n  ]\n}\n```\n\nFor project-level Claude Code skills, add to `.pi/settings.json`:\n\n```json\n{\n  \"skills\": [\"../.claude/skills\"]\n}\n```\n\n## How Skills Work\n\n1. At startup, pi scans skill locations and extracts names and descriptions\n2. The system prompt includes available skills in XML format per the [specification](https://agentskills.io/integrate-skills)\n3. 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)\n4. The agent follows the instructions, using relative paths to reference scripts and assets\n\nThis is progressive disclosure: only descriptions are always in context, full instructions load on-demand.\n\n## Skill Commands\n\nSkills register as `/skill:name` commands:\n\n```bash\n/skill:brave-search           # Load and execute the skill\n/skill:pdf-tools extract      # Load skill with arguments\n```\n\nArguments after the command are appended to the skill content as `User: <args>`.\n\nToggle skill commands via `/settings` in interactive mode or in `settings.json`:\n\n```json\n{\n  \"enableSkillCommands\": true\n}\n```\n\n## Skill Structure\n\nA skill is a directory with a `SKILL.md` file. Everything else is freeform.\n\n```\nmy-skill/\n├── SKILL.md              # Required: frontmatter + instructions\n├── scripts/              # Helper scripts\n│   └── process.sh\n├── references/           # Detailed docs loaded on-demand\n│   └── api-reference.md\n└── assets/\n    └── template.json\n```\n\n### SKILL.md Format\n\n````markdown\n---\nname: my-skill\ndescription: What this skill does and when to use it. Be specific.\n---\n\n# My Skill\n\n## Setup\n\nRun once before first use:\n```bash\ncd /path/to/skill && npm install\n```\n\n## Usage\n\n```bash\n./scripts/process.sh <input>\n```\n````\n\nUse relative paths from the skill directory:\n\n```markdown\nSee [the reference guide](references/REFERENCE.md) for details.\n```\n\n## Frontmatter\n\nPer the [Agent Skills specification](https://agentskills.io/specification#frontmatter-required):\n\n| Field | Required | Description |\n|-------|----------|-------------|\n| `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. |\n| `description` | Yes | Max 1024 chars. What the skill does and when to use it. |\n| `license` | No | License name or reference to bundled file. |\n| `compatibility` | No | Max 500 chars. Environment requirements. |\n| `metadata` | No | Arbitrary key-value mapping. |\n| `allowed-tools` | No | Space-delimited list of pre-approved tools (experimental). |\n| `disable-model-invocation` | No | When `true`, skill is hidden from system prompt. Users must use `/skill:name`. |\n\n### Name Rules\n\n- 1-64 characters\n- Lowercase letters, numbers, hyphens only\n- No leading/trailing hyphens\n- No consecutive hyphens\nPi 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.\n\nValid: `pdf-processing`, `data-analysis`, `code-review`\nInvalid: `PDF-Processing`, `-pdf`, `pdf--processing`\n\n### Description Best Practices\n\nThe description determines when the agent loads the skill. Be specific.\n\nGood:\n```yaml\ndescription: Extracts text and tables from PDF files, fills PDF forms, and merges multiple PDFs. Use when working with PDF documents.\n```\n\nPoor:\n```yaml\ndescription: Helps with PDFs.\n```\n\n## Validation\n\nPi validates skills against the Agent Skills standard. Most issues produce warnings but still load the skill:\n\n- Name exceeds 64 characters or contains invalid characters\n- Name starts/ends with hyphen or has consecutive hyphens\n- Description exceeds 1024 characters\n\nUnknown frontmatter fields are ignored.\n\n**Exception:** Skills with missing description are not loaded.\n\nName collisions (same name from different locations) warn and keep the first skill found.\n\n## Example\n\n```\nbrave-search/\n├── SKILL.md\n├── search.js\n└── content.js\n```\n\n**SKILL.md:**\n````markdown\n---\nname: brave-search\ndescription: Web search and content extraction via Brave Search API. Use for searching documentation, facts, or any web content.\n---\n\n# Brave Search\n\n## Setup\n\n```bash\ncd /path/to/brave-search && npm install\n```\n\n## Search\n\n```bash\n./search.js \"query\"              # Basic search\n./search.js \"query\" --content    # Include page content\n```\n\n## Extract Page Content\n\n```bash\n./content.js https://example.com\n```\n````\n\n## Skill Repositories\n\n- [Anthropic Skills](https://github.com/anthropics/skills) - Document processing (docx, pdf, pptx, xlsx), web development\n- [Pi Skills](https://github.com/badlogic/pi-skills) - Web search, browser automation, Google APIs, transcription\n","is_error":false}]}},{"step_id":3,"source":"agent","timestamp":"2026-08-13T18:38:21.553000+00:00","message":"<think>\nThe user asked me to read the skills documentation to understand how to use skills in pi.
