Default-off and per-agent: a custom agent receives scoped `Agent`, `get_subagent_result`, and `steer_subagent` tools only when its frontmatter sets `allowed_subagents` (a comma-separated type list, or `all` — `true` and `\"*\"` are accepted the way `extensions:`/`skills:` take booleans), and never when it is `isolated`. The allowlist is a privilege boundary rather than a routing hint: a child runs with its own `tools:`, `extensions:`, and `isolated:`, so delegating grants the parent the union of what the listed agents can do — `all` reaches `general-purpose`. Nesting is depth-capped from the main session — main is 0, its subagents 1, their children 2 — through `maxSubagentDepth` in `subagents.json` (default `2`; `0` or `1` disables nesting project-wide) or `/agents → Settings → Nested depth`. A per-agent cap is deliberately not exposed yet: at the default project cap it could only restate what omitting `allowed_subagents` already says, and a tighten-only field is safe to add once someone raises that cap. An agent already at the cap is given no nested tools at all, rather than tools whose every call would fail. Everything a parent can do is ownership-scoped — it can fetch, resume, and steer only its own children — and unknown, disabled, or out-of-list types are refused rather than falling back to general-purpose. Nested spawns resolve agents from a registry built for their own config root (never the process-global registry the main session uses) and revalidate `model:` against Model Scope exactly like a top-level spawn. Nested records stay internal to their parent, absent from top-level tools, lifecycle events, and the agent UI, and are stopped when that parent finishes, is stopped, or ends a resumed turn — a hidden child must not outlive the only agent able to reach it. They still write their own `.output` transcript under the root session's directory (same `output_transcript` gate), so a nested run remains inspectable, and their token usage is folded into every ancestor's totals so nested spend stays attributable at any depth, and a nested result that ends `stopped`, `aborted`, or `steered` is labelled partial, the same guarantee top-level results carry. Nested children do not occupy `maxConcurrent` slots: their parent already holds one, and queueing them behind it would deadlock a parent waiting on its own child; the depth cap bounds how deep nesting goes, not how wide, so a `max_turns` on the delegating agent is what ceilings its fan-out. A subagent session no longer activates this extension at all — that is what keeps a child from building a second agent manager, and it is why the nested tools are injected directly instead; a subagent consequently also gets no `/agents` command, no cross-extension RPC handlers, and no `subagents:ready` event.\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:17:- **A disabled agent is no longer dispatchable, and no longer runs with a mixed identity** (found while implementing [#183](https://github.com/tintinweb/pi-subagents/issues/183)). The `Agent` tool resolved types with `resolveType()`, which reports a canonical name without checking `enabled` — so an agent disabled via `enabled: false` or `/agents → Disable` resolved successfully, produced no fallback note, and then split downstream: `getAgentConfig` returned the disabled agent's config to build the system prompt while `getConfig` returned general-purpose for tools, extensions, skills and prompt mode. The run therefore carried the disabled agent's instructions with a different agent's tool policy. Dispatch now requires the type to resolve to exactly one *enabled* agent, so a disabled type takes the fallback path — or is refused outright under `fallbackSubagent: none`.\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:27:- **User-scope agent memory honors `PI_CODING_AGENT_DIR`** ([#166](https://github.com/tintinweb/pi-subagents/pull/166) — thanks [@biowaffeln](https://github.com/biowaffeln)). The `user` memory scope hardcoded `~/.pi/agent-memory/`, ignoring `PI_CODING_AGENT_DIR` even though every other config consumer (custom agents, enabled models, settings, skills) already routes through `getAgentDir()` — so anyone who relocated their config dir got a stray `~/.pi` resurrected the first time a `memory: user` agent ran. User-scope memory now resolves to `/agent-memory/` (default `~/.pi/agent/agent-memory/`). Existing memories aren't orphaned: when the legacy `~/.pi/agent-memory/` directory exists and the new location doesn't, it keeps being used — symlinked legacy dirs are ignored, consistent with the file's other symlink defenses — and once the new location exists it wins. Lazy fallback rather than auto-migration, so no files are moved.\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:51:- **Project custom agents are also discovered from `.agents/agents/.md`** ([#133](https://github.com/tintinweb/pi-subagents/pull/133) — thanks [@wenerme](https://github.com/wenerme); closes [#132](https://github.com/tintinweb/pi-subagents/issues/132)). Projects that keep their agent assets in the shared cross-tool `.agents` workspace (the same convention this extension already reads for `.agents/skills/`) can now define subagents there instead of duplicating files into `.pi/agents/`. Discovery precedence is `global < .agents/agents < .pi/agents`: on a name clash between the two project locations, **`.pi/agents/` wins** — `.pi` remains the project authority, and the `/agents` create/eject/disable flows keep writing there; `.agents/agents/` is a read location only.\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:96:- **`SpawnOptions.cwd` — spawn a subagent in a different working directory** ([#96](https://github.com/tintinweb/pi-subagents/issues/96) — thanks [@madeleineostoja](https://github.com/madeleineostoja)). For RPC/programmatic callers (not exposed on the `Agent` tool — the LLM-visible surface is unchanged). The agent's tools operate in the target directory and the prompt's environment block describes it, but **`.pi` config keeps loading from the parent session's project** (new `RunOptions.configCwd` split): the target's `.pi` extensions never execute, and its agents/skills/settings/memory are not picked up — spawning into an untrusted directory sends a worker there with the parent's toolbox, rather than \"opening pi there.\" Composes with `isolation: \"worktree\"`: the worktree is created *from* the target directory's repo, the agent works at the equivalent subdirectory inside the copy (a monorepo-package cwd keeps its scoping instead of silently widening to the repo root — new `WorktreeInfo.workPath`), and the resulting `pi-agent-*` branch lands in that repo, with the completion message naming it so the orchestrator merges in the right place. Validation is strict, typed, and early — non-strings, relative paths, nonexistent paths, and files all throw curated errors at `spawn()` (before queueing) and are re-checked at queue drain, surfacing as RPC error envelopes (`null` is treated as unset). On dispose, worktree registrations are pruned in every repo that received one; only a hard crash can leave a stale entry (then: `git worktree prune` in the target repo).\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:102:- **`toolDescriptionMode` setting — opt-in compact Agent tool description** ([#91](https://github.com/tintinweb/pi-subagents/issues/91) — thanks [@tiberiuichim](https://github.com/tiberiuichim)). The full Claude Code-style description costs ~1,400 tokens with the default agents and grows with each custom agent (the type list embeds full agent descriptions) — significant for small/local models. `toolDescriptionMode: \"compact\"` (via `/agents → Settings → Tool description` or `subagents.json`) swaps in a ~75% smaller description: one-line type list (first sentence of each agent description), terse usage notes, per-option details left to the parameter descriptions. Default `\"full\"` is byte-identical to before — the rich description's guardrails are deliberately load-bearing and stay the default. A third mode, `\"custom\"`, registers a user-authored description from `/.pi/agent-tool-description.md` (project) or `/agent-tool-description.md` (global; project wins), with `{{placeholder}}` substitution keeping the dynamic parts live — `{{typeList}}`, `{{compactTypeList}}`, `{{agentDir}}`, `{{scheduleGuideline}}` — so a hand-written description can't drift out of sync with the registered agents (the advertised-vs-spawnable staleness [#92](https://github.com/tintinweb/pi-subagents/issues/92) just fixed). Unknown placeholders are left verbatim with a stderr warning; a missing/empty file falls back to `\"full\"`. Only the prose is customizable — the parameter schema stays code-owned. A ready-made starting point ships at `examples/agent-tool-description.md`, reproducing the full description exactly (CI-enforced byte-identical, so the example can't go stale). Like `schedulingEnabled`, the mode is read at tool registration — changing it applies on the next pi session. The issue's original ask (move the description to a skill) isn't possible in pi: tools must register their description in the tool schema for the model to call them; skills are lazily-loaded instructions, not tool registrations.\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:192:> **Heads-up — behavior changes in skill preloading:**\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:193:> - **`.txt` and extensionless flat skill files are no longer loaded.** Only `.md` flat files and `/SKILL.md` directory skills resolve now.

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 ` (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: `.\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 \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\n[32 more lines in file.

Default-off and per-agent: a custom agent receives scoped `Agent`, `get_subagent_result`, and `steer_subagent` tools only when its frontmatter sets `allowed_subagents` (a comma-separated type list, or `all` — `true` and `\"*\"` are accepted the way `extensions:`/`skills:` take booleans), and never when it is `isolated`. The allowlist is a privilege boundary rather than a routing hint: a child runs with its own `tools:`, `extensions:`, and `isolated:`, so delegating grants the parent the union of what the listed agents can do — `all` reaches `general-purpose`. Nesting is depth-capped from the main session — main is 0, its subagents 1, their children 2 — through `maxSubagentDepth` in `subagents.json` (default `2`; `0` or `1` disables nesting project-wide) or `/agents → Settings → Nested depth`. A per-agent cap is deliberately not exposed yet: at the default project cap it could only restate what omitting `allowed_subagents` already says, and a tighten-only field is safe to add once someone raises that cap. An agent already at the cap is given no nested tools at all, rather than tools whose every call would fail. Everything a parent can do is ownership-scoped — it can fetch, resume, and steer only its own children — and unknown, disabled, or out-of-list types are refused rather than falling back to general-purpose. Nested spawns resolve agents from a registry built for their own config root (never the process-global registry the main session uses) and revalidate `model:` against Model Scope exactly like a top-level spawn. Nested records stay internal to their parent, absent from top-level tools, lifecycle events, and the agent UI, and are stopped when that parent finishes, is stopped, or ends a resumed turn — a hidden child must not outlive the only agent able to reach it. They still write their own `.output` transcript under the root session's directory (same `output_transcript` gate), so a nested run remains inspectable, and their token usage is folded into every ancestor's totals so nested spend stays attributable at any depth, and a nested result that ends `stopped`, `aborted`, or `steered` is labelled partial, the same guarantee top-level results carry. Nested children do not occupy `maxConcurrent` slots: their parent already holds one, and queueing them behind it would deadlock a parent waiting on its own child; the depth cap bounds how deep nesting goes, not how wide, so a `max_turns` on the delegating agent is what ceilings its fan-out. A subagent session no longer activates this extension at all — that is what keeps a child from building a second agent manager, and it is why the nested tools are injected directly instead; a subagent consequently also gets no `/agents` command, no cross-extension RPC handlers, and no `subagents:ready` event.\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:17:- **A disabled agent is no longer dispatchable, and no longer runs with a mixed identity** (found while implementing [#183](https://github.com/tintinweb/pi-subagents/issues/183)). The `Agent` tool resolved types with `resolveType()`, which reports a canonical name without checking `enabled` — so an agent disabled via `enabled: false` or `/agents → Disable` resolved successfully, produced no fallback note, and then split downstream: `getAgentConfig` returned the disabled agent's config to build the system prompt while `getConfig` returned general-purpose for tools, extensions, skills and prompt mode. The run therefore carried the disabled agent's instructions with a different agent's tool policy. Dispatch now requires the type to resolve to exactly one *enabled* agent, so a disabled type takes the fallback path — or is refused outright under `fallbackSubagent: none`.\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:27:- **User-scope agent memory honors `PI_CODING_AGENT_DIR`** ([#166](https://github.com/tintinweb/pi-subagents/pull/166) — thanks [@biowaffeln](https://github.com/biowaffeln)). The `user` memory scope hardcoded `~/.pi/agent-memory/`, ignoring `PI_CODING_AGENT_DIR` even though every other config consumer (custom agents, enabled models, settings, skills) already routes through `getAgentDir()` — so anyone who relocated their config dir got a stray `~/.pi` resurrected the first time a `memory: user` agent ran. User-scope memory now resolves to `/agent-memory/` (default `~/.pi/agent/agent-memory/`). Existing memories aren't orphaned: when the legacy `~/.pi/agent-memory/` directory exists and the new location doesn't, it keeps being used — symlinked legacy dirs are ignored, consistent with the file's other symlink defenses — and once the new location exists it wins. Lazy fallback rather than auto-migration, so no files are moved.\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:51:- **Project custom agents are also discovered from `.agents/agents/.md`** ([#133](https://github.com/tintinweb/pi-subagents/pull/133) — thanks [@wenerme](https://github.com/wenerme); closes [#132](https://github.com/tintinweb/pi-subagents/issues/132)). Projects that keep their agent assets in the shared cross-tool `.agents` workspace (the same convention this extension already reads for `.agents/skills/`) can now define subagents there instead of duplicating files into `.pi/agents/`. Discovery precedence is `global < .agents/agents < .pi/agents`: on a name clash between the two project locations, **`.pi/agents/` wins** — `.pi` remains the project authority, and the `/agents` create/eject/disable flows keep writing there; `.agents/agents/` is a read location only.\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:96:- **`SpawnOptions.cwd` — spawn a subagent in a different working directory** ([#96](https://github.com/tintinweb/pi-subagents/issues/96) — thanks [@madeleineostoja](https://github.com/madeleineostoja)). For RPC/programmatic callers (not exposed on the `Agent` tool — the LLM-visible surface is unchanged). The agent's tools operate in the target directory and the prompt's environment block describes it, but **`.pi` config keeps loading from the parent session's project** (new `RunOptions.configCwd` split): the target's `.pi` extensions never execute, and its agents/skills/settings/memory are not picked up — spawning into an untrusted directory sends a worker there with the parent's toolbox, rather than \"opening pi there.\" Composes with `isolation: \"worktree\"`: the worktree is created *from* the target directory's repo, the agent works at the equivalent subdirectory inside the copy (a monorepo-package cwd keeps its scoping instead of silently widening to the repo root — new `WorktreeInfo.workPath`), and the resulting `pi-agent-*` branch lands in that repo, with the completion message naming it so the orchestrator merges in the right place. Validation is strict, typed, and early — non-strings, relative paths, nonexistent paths, and files all throw curated errors at `spawn()` (before queueing) and are re-checked at queue drain, surfacing as RPC error envelopes (`null` is treated as unset). On dispose, worktree registrations are pruned in every repo that received one; only a hard crash can leave a stale entry (then: `git worktree prune` in the target repo).\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:102:- **`toolDescriptionMode` setting — opt-in compact Agent tool description** ([#91](https://github.com/tintinweb/pi-subagents/issues/91) — thanks [@tiberiuichim](https://github.com/tiberiuichim)). The full Claude Code-style description costs ~1,400 tokens with the default agents and grows with each custom agent (the type list embeds full agent descriptions) — significant for small/local models. `toolDescriptionMode: \"compact\"` (via `/agents → Settings → Tool description` or `subagents.json`) swaps in a ~75% smaller description: one-line type list (first sentence of each agent description), terse usage notes, per-option details left to the parameter descriptions. Default `\"full\"` is byte-identical to before — the rich description's guardrails are deliberately load-bearing and stay the default. A third mode, `\"custom\"`, registers a user-authored description from `/.pi/agent-tool-description.md` (project) or `/agent-tool-description.md` (global; project wins), with `{{placeholder}}` substitution keeping the dynamic parts live — `{{typeList}}`, `{{compactTypeList}}`, `{{agentDir}}`, `{{scheduleGuideline}}` — so a hand-written description can't drift out of sync with the registered agents (the advertised-vs-spawnable staleness [#92](https://github.com/tintinweb/pi-subagents/issues/92) just fixed). Unknown placeholders are left verbatim with a stderr warning; a missing/empty file falls back to `\"full\"`. Only the prose is customizable — the parameter schema stays code-owned. A ready-made starting point ships at `examples/agent-tool-description.md`, reproducing the full description exactly (CI-enforced byte-identical, so the example can't go stale). Like `schedulingEnabled`, the mode is read at tool registration — changing it applies on the next pi session. The issue's original ask (move the description to a skill) isn't possible in pi: tools must register their description in the tool schema for the model to call them; skills are lazily-loaded instructions, not tool registrations.\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:192:> **Heads-up — behavior changes in skill preloading:**\n/root/.pi/agent/npm/node_modules/@tintinweb/pi-subagents/CHANGELOG.md:193:> - **`.txt` and extensionless flat skill files are no longer loaded.** Only `.md` flat files and `/SKILL.md` directory skills resolve now.

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 ` (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: `.\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 \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.
