It safely clears:\n- Build caches\n- Package caches\n- Temporary files\n\nIt features:\n- Smart cache detection\n- Safe deletion with confirmation\n- Disk space recovery reports\n- Multi-platform support\n\n---\n\n## 2. How to use it\n\n**Commands:**\n```bash\n/cache-cleaner scan\n/cache-cleaner clean --all\n/cache-cleaner clean --npm --pip --docker\n```\n\n**Direct script usage:**\n```bash\n# Run the cache cleaner (safe mode - default)\n./scripts/cache_cleaner.sh clean\n\n# Or with aggressive mode (deep clean)\n./scripts/cache_cleaner.sh clean aggressive\n```\n\n**Core functions:**\n- `clean_caches safe` - Clean known cache locations\n- `clean_caches aggressive` - Deep clean all cache directories\n- `deep_clean /var/cache` - Deep cleaning for thorough cleanup\n- `recover_space ~/Downloads/tmp ~/Projects/build` - Recover disk space by removing specified directories\n\n---\n\n## 3. Cache directories it targets\n\nThe skill supports cleaning caches for:\n\n| Category | Tools |\n|----------|-------|\n| Node.js | npm, yarn, pnpm |\n| Python | pip, conda |\n| Containers | Docker, Podman |\n| Build tools | Maven, Gradle |\n| Package managers | Homebrew |\n\n---\n\n**Location:** `/root/.pi/agent/skills/cache-cleaner/`\n\nThe skill also includes additional documentation at `/root/.nvm/versions/node/v22.23.2/lib/node_modules/@earendil-works/pi-coding-agent/docs/skills.md` which explains how skills work in pi generally - they are self-contained capability packages loaded on-demand that provide specialized workflows and helper scripts.","is_error":false}]}},{"step_id":3,"source":"agent","timestamp":"2026-08-13T01:43:03.552000+00:00","message":"<think>\nThe user wants me to clean up project cache files.

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":"2026-08-13T01:42:57.837000+00:00","message":"<think>\nThe user wanted to understand the cache-cleaner skill.

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.

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.
