Activate when developing new skills or\n  refining existing ones.\nlicense: Apache-2.0\nmetadata:\n  category: agents\n  tags: \"skills, agent-skills, optimization, standards\"\n  author: Daniela Petruzalek (daniela@danicat.dev)\n  version: \"0.5.0\"\n  catalog: https://skills.danicat.dev\n---\n\n# Agent Skill Optimizer\n\nProcedures, authoring principles, and quality standards for creating, auditing, and optimizing Agent Skills according to the Agent Skills specification and open-source best practices.\n\n## Available scripts\n\n- **`scripts/count_tokens.py`** — Audits skills and categories against Tier 1, 2, and 3 token limits using Vertex AI ADC, Gemini API, or offline heuristic.\n\n---\n\n## Skill Architecture & Progressive Disclosure Limits\n\nSkills use a 3-tier progressive disclosure model to minimize token consumption:\n\n1. **Tier 1 — Routing & Discovery Metadata** (~50–100 words / $\\le 150$ tokens):\n   - **Fields**: `name` (1–64 characters) and `description` (1–1024 characters).\n   - **Runtime behavior**: Injected into the model's system prompt at startup for all available skills so the orchestrator can route tasks accurately.\n   - **Budget limit**: Keep routing tokens $\\le 150$ (ideal ~100 tokens). Keep description $\\le 1024$ characters.\n\n2. **Tier 2 — Skill Instructions & Body** (< 5,000 tokens / < 500 lines):\n   - **Scope**: The main `SKILL.md` body (excluding frontmatter).\n   - **Runtime behavior**: Loaded into active context only when the skill is explicitly activated.\n   - **Budget limit**: Strict limit of $\\le 5,000$ tokens and $\\le 500$ lines. Move detailed API tables, expansive guides, and catalogs into Tier 3.\n\n3. **Tier 3 — On-Demand Resources & References**:\n   - **Scope**: Subdirectories loaded only when explicitly requested by instructions:\n     - `references/`: Domain guides, schemas, cheat sheets, and syntax rules. Formatted as **Open Knowledge Format (OKF v0.2)** concept markdown documents with YAML frontmatter (`type`, `resource`, `sources`, `verified`) and an `index.md` bundle map for progressive disclosure.\n     - `scripts/`: Executable helper tools and automation scripts.\n     - `assets/`: Static templates, seed data, or boilerplate files.\n\n---\n\n## Frontmatter Specification & Metadata Guidelines\n\nEvery skill must provide valid YAML frontmatter containing core identifiers, licensing, and an authoritative canonical URL:\n\n```yaml\n---\nname: my-skill\ndescription: >\n  Concise definition of the skill and tangible topics covered. Mentions key\n  architecture or superpower. Activate when encountering primary use case or\n  problem conditions.\nlicense: Apache-2.0\nmetadata:\n  category: coding\n  tags: \"go, refactoring, testing, quality\"\n  author: Maintainer Name (maintainer@example.com)\n  version: \"1.0.0\"\n  canonical: https://skills.example.com/coding/my-skill/\ncompatibility: Requires Go 1.22+\nallowed-tools: Bash(go:*) Read\n---\n```\n\n### Field Rules & Single-URL Provenance\n\n#### 1. Core Top-Level Fields\n- `name` (required): 1-64 characters, lowercase alphanumeric and single hyphens (`a-z`, `0-9`, `-`). No consecutive hyphens (`--`), no leading/trailing hyphens. Must match directory name exactly.\n- `description` (required): 1-1024 characters. Non-empty. Follows the 3-Part Skill Description Blueprint (Definition & Scope + Superpower + Human Triggers). Do not include internal implementation plumbing.\n- `license` (required): Short SPDX license identifier (e.g., `Apache-2.0`, `MIT`) or path to a bundled license.\n- `compatibility` (optional): Environment or tool requirements (e.g., `Requires Python 3.11+`). Omit if standard.\n- `allowed-tools` (optional): Space-separated list of pre-approved tools (experimental).\n\n#### 2. Metadata Block (`metadata`)\n- `category` (recommended): Functional taxonomy domain (e.g., `coding`, `agents`, `devops`, `media`, `writing`, `analytics`). Recommended to match the parent category folder name in structured repositories.\n- `tags` (recommended): 3 to 6 high-level domain anchors for search and categorization. Avoid redundant synonym stuffing.\n- `author` (recommended): Maintainer attribution string (e.g., `Author Name (email@example.com)` or organization name).\n- `version` (recommended): Semantic Versioning SemVer 2.0.0 (`MAJOR.MINOR.PATCH`).\n- `canonical` (recommended): The authoritative web URL pointing to the skill's published documentation (e.g., `https://skills.example.com/<category>/<skill-name>/`).\n  - **Single Canonical URL Standard**: Avoid duplicating `homepage` and `repository` fields in frontmatter when a single canonical URL suffices. This reduces metadata overhead by ~60–80 tokens per skill while maintaining full provenance.\n\n#### 3. Zero Contamination Gate\nAll public skills must be strictly generic, modular, and platform-agnostic:\n- **No local machine specifics**: Never include personal machine paths or local home directory structures.\n- **No internal corporate knowledge**: Never include internal project names, private channel names, or proprietary infrastructure URLs.\n- **No credentials or tokens**: Never leak API keys, personal access tokens, or private secrets.\n\n---\n\n## Optional Reference: Agent Skills MCP Server\n\nTo query live specifications and documentation during development, you can connect the Agent Skills MCP server:\n\n- **Server URL**: `https://agentskills.io/mcp`\n- **MCP Configuration** (e.g., `~/.gemini/config/mcp_config.json` or `claude_desktop_config.json`):\n```json\n{\n  \"mcpServers\": {\n    \"agentskills\": {\n      \"url\": \"https://agentskills.io/mcp\"\n    }\n  }\n}\n```\n\n---\n\n## 5-Stage Skill Audit & Optimization Process\n\nFollow this procedure when creating, reviewing, or refining skills:\n\n### Stage 1: Structure & File Layout\n- **Name Alignment**: Confirm `name` in frontmatter matches the directory name exactly.\n- **Tier 1 & Tier 2 Limits**: Verify routing budget ($\\le 150$ tokens, $\\le 1024$ chars) and body budget ($\\le 5,000$ tokens, $\\le 500$ lines) using `scripts/count_tokens.py`.\n- **Progressive Disclosure**: Move extensive documentation (> 100 lines), schemas, or static data into `references/` or `assets/`.\n- **Clean Relative Paths from Skill Root**: All internal file and script references in `SKILL.md` MUST use relative paths starting from the skill root directory (e.g., `scripts/process.py`, `references/guide.md`, `assets/template.md`).\n  - **No category prefixes**: Use `scripts/tool.py`, never `category/skill-name/scripts/tool.py`.\n  - **No placeholders**: Use `scripts/tool.py`, never `{skillDir}/scripts/tool.py` or `{baseDir}/scripts/tool.py`.\n  - **No absolute paths**: The agent harness resolves relative paths against the skill base directory automatically.\n- **Available Scripts Discovery**: List bundled scripts in an `## Available scripts` section in `SKILL.md` so the agent immediately discovers available tools.\n- **Conditional Loading**: Clearly state *when* the agent should read each reference file.\n\n#### Auditing Skills with Bundled `scripts/count_tokens.py`\nAudit skills against Tier 1, Tier 2, and Tier 3 limits using the self-contained PEP 723 Python script:\n\n```bash\n# 1. Audit a single skill\nuv run scripts/count_tokens.py ../../coding/godoctor/SKILL.md\n\n# 2. Audit a category directory of skills\nuv run scripts/count_tokens.py ../../coding/\n\n# 3. Fast offline audit (uses ~4 chars/token heuristic, no API or network calls)\nuv run scripts/count_tokens.py ../../agents/ --heuristic-only\n\n# 4. Machine-readable JSON output (for CI/CD pipelines)\nuv run scripts/count_tokens.py ../../coding/godoctor/SKILL.md --json\n```\n\n**Authentication & Models**:\n- **Vertex AI ADC (Default)**: Automatically detects Application Default Credentials (`gcloud auth application-default login`) with model `gemini-3.7-flash` and location `global`.\n- **Gemini Developer API**: Set `export GEMINI_API_KEY=\"...\"` to authenticate directly via Gemini API.\n- **Offline Fallback**: Automatically falls back to an offline ~4 chars/token heuristic if no network or credentials are available.\n\n### Stage 2: Description, Trigger & Tag Optimization\n\nThe frontmatter `description` is the primary text loaded by orchestrators at startup to determine activation. Craft every `description` against this 3-part blueprint:\n\n```\n[1. Concrete Definition & Scope] + [2. Architectural Superpower / Key Topics] + [3. Natural, Decisive Trigger]\n```\n\n1. **Concrete Definition & Scope**:\n   - State what the skill does in plain, direct English.\n   - Enumerate tangible topics, formats, and artifacts covered.\n   - Use universal mental models (e.g., *\"Divide to Conquer approach\"*).\n   - Avoid narrating a play-by-play checklist in the description.\n2. **Key Architecture / Superpower**:\n   - State the technical capability plainly (e.g., *\"uses parallel subagents to ensure context isolation\"*).\n   - Explain why the approach matters for quality and reliability.\n   - Use open, illustrative examples (e.g., *\"connected channels (such as LinkedIn, X/Twitter, Bluesky, and others)\"*).\n   - Do not waste tokens explaining internal algorithms or private code plumbing (e.g., AST parsing, regex, SQLite internals).\n3. **Decisive Triggers**:\n   - Include explicit domain terms and tool names.\n   - Anchor triggers to user intent and problem characteristics (e.g., *\"when tackling problems that require out of the box thinking\"*, *\"when developing new skills or refining existing ones\"*).\n\n#### Trigger Discipline (The Anti-Pushy Rule)\n- **Eliminate Artificial Coercion**: Avoid phrases like *\"Activate even if the user does not explicitly mention...\"* or *\"Trigger whenever anything related is requested\"*. Overly aggressive trigger language causes false positives and pollutes the context window during multi-turn chats.\n- **Describe Problem Traits, Not Model Behavior**: Guide the orchestrator by detailing the **problem symptoms**, **task objectives**, and **domain vocabulary** that uniquely require this skill. Let clear architectural boundaries drive routing decisions naturally.\n\n#### Tag Taxonomy Guidelines\n- Choose **3 to 6 high-level domain anchors** for search indices.\n- **Do NOT repeat the skill name as a tag**: The `name` is already indexed. Repeating it wastes tag budget.\n- **Avoid generic noise tags**: Words like `cli` or `hierarchy` convey minimal context. Use domain-specific anchors like `management` or `structure`.\n- **Omit implementation details**: Skip low-level tags (`sqlite`) when high-level intent tags (`sql`, `analytics`) are present.\n- **Include brand/ecosystem anchors** when scoped specifically (e.g., `google` for Google-specific standards).\n\n### Stage 3: Core Principles for Skill Body Design\n\nEvery skill body must adhere to these 6 instructional standards:\n\n1. **Teach Practices, Not Passive Declarations**:\n   - Provide concrete, repeatable workflows, architectural patterns, commands, and debugging steps.\n   - Focus on what the agent should *do*, *check*, and *produce*, rather than reciting encyclopedia definitions.\n\n2. **Readability & Clear Scannability**:\n   - Maintain clear sentence structure and high scannability (aim for Fog Index ~12–15 with leeway for technical syntax).\n   - Avoid dense walls of text; organize multi-step procedures into structured checklists (`- [ ] Step 1...`).\n\n3. **Zero Marketing, Buzzwords & Fake Qualifiers**:\n   - Never use marketing buzzwords (*\"vibrant\"*, *\"cutting-edge\"*, *\"blazing-fast\"*, *\"world-class\"*, *\"bespoke\"*, *\"game-changing\"*).\n   - Never use fake technical qualifiers (*\"high signal SQLite WAL Engine\"* ❌). State capabilities plainly (*\"SQLite database\"* ✅).\n\n4. **Usability Over Implementation Plumbing**:\n   - Emphasize the interface the agent interacts with (e.g., `SQLite` tells the agent to query via SQL).\n   - Omit internal runtime trivia that does not affect agent intera","tagline":"Comprehensive guide to develop and improve Agent Skill performance.
