Agent Skill Optimizer

Procedures, authoring principles, and quality standards for creating, auditing, and optimizing Agent Skills according to the Agent Skills specification and open-source best practices.

Available scripts

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.

Skill Architecture & Progressive Disclosure Limits

Skills use a 3-tier progressive disclosure model to minimize token consumption:

Tier 1 — Routing & Discovery Metadata (~50–100 words / $\le 150$ tokens):
- Fields: name (1–64 characters) and description (1–1024 characters).
- Runtime behavior: Injected into the model's system prompt at startup for all available skills so the orchestrator can route tasks accurately.
- Budget limit: Keep routing tokens $\le 150$ (ideal ~100 tokens). Keep description $\le 1024$ characters.
Tier 2 — Skill Instructions & Body (< 5,000 tokens / < 500 lines):
- Scope: The main SKILL.md body (excluding frontmatter).
- Runtime behavior: Loaded into active context only when the skill is explicitly activated.
- Budget limit: Strict limit of $\le 5,000$ tokens and $\le 500$ lines. Move detailed API tables, expansive guides, and catalogs into Tier 3.
Tier 3 — On-Demand Resources & References:
- Scope: Subdirectories loaded only when explicitly requested by instructions:
  - 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.
  - scripts/: Executable helper tools and automation scripts.
  - assets/: Static templates, seed data, or boilerplate files.

Frontmatter Specification & Metadata Guidelines

Every skill must provide valid YAML frontmatter containing core identifiers, licensing, and an authoritative canonical URL:

---
name: my-skill
description: >
  Concise definition of the skill and tangible topics covered. Mentions key
  architecture or superpower. Activate when encountering primary use case or
  problem conditions.
license: Apache-2.0
metadata:
  category: coding
  tags: "go, refactoring, testing, quality"
  author: Maintainer Name (maintainer@example.com)
  version: "1.0.0"
  canonical: https://skills.example.com/coding/my-skill/
compatibility: Requires Go 1.22+
allowed-tools: Bash(go:*) Read
---

Field Rules & Single-URL Provenance

1. Core Top-Level Fields

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.
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.
license (required): Short SPDX license identifier (e.g., Apache-2.0, MIT) or path to a bundled license.
compatibility (optional): Environment or tool requirements (e.g., Requires Python 3.11+). Omit if standard.
allowed-tools (optional): Space-separated list of pre-approved tools (experimental).

2. Metadata Block (`metadata`)

category (recommended): Functional taxonomy domain (e.g., coding, agents, devops, media, writing, analytics). Recommended to match the parent category folder name in structured repositories.
tags (recommended): 3 to 6 high-level domain anchors for search and categorization. Avoid redundant synonym stuffing.
author (recommended): Maintainer attribution string (e.g., Author Name (email@example.com) or organization name).
version (recommended): Semantic Versioning SemVer 2.0.0 (MAJOR.MINOR.PATCH).
canonical (recommended): The authoritative web URL pointing to the skill's published documentation (e.g., https://skills.example.com/<category>/<skill-name>/).
- 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.

3. Zero Contamination Gate

All public skills must be strictly generic, modular, and platform-agnostic:

No local machine specifics: Never include personal machine paths or local home directory structures.
No internal corporate knowledge: Never include internal project names, private channel names, or proprietary infrastructure URLs.
No credentials or tokens: Never leak API keys, personal access tokens, or private secrets.

Optional Reference: Agent Skills MCP Server

To query live specifications and documentation during development, you can connect the Agent Skills MCP server:

Server URL: https://agentskills.io/mcp
MCP Configuration (e.g., ~/.gemini/config/mcp_config.json or claude_desktop_config.json):

{
  "mcpServers": {
    "agentskills": {
      "url": "https://agentskills.io/mcp"
    }
  }
}

5-Stage Skill Audit & Optimization Process

Follow this procedure when creating, reviewing, or refining skills:

Stage 1: Structure & File Layout

Name Alignment: Confirm name in frontmatter matches the directory name exactly.
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.
Progressive Disclosure: Move extensive documentation (> 100 lines), schemas, or static data into references/ or assets/.
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).
- No category prefixes: Use scripts/tool.py, never category/skill-name/scripts/tool.py.
- No placeholders: Use scripts/tool.py, never {skillDir}/scripts/tool.py or {baseDir}/scripts/tool.py.
- No absolute paths: The agent harness resolves relative paths against the skill base directory automatically.
Available Scripts Discovery: List bundled scripts in an ## Available scripts section in SKILL.md so the agent immediately discovers available tools.
Conditional Loading: Clearly state when the agent should read each reference file.

Auditing Skills with Bundled `scripts/count_tokens.py`

Audit skills against Tier 1, Tier 2, and Tier 3 limits using the self-contained PEP 723 Python script:

# 1. Audit a single skill
uv run scripts/count_tokens.py ../../coding/godoctor/SKILL.md

# 2. Audit a category directory of skills
uv run scripts/count_tokens.py ../../coding/

# 3. Fast offline audit (uses ~4 chars/token heuristic, no API or network calls)
uv run scripts/count_tokens.py ../../agents/ --heuristic-only

# 4. Machine-readable JSON output (for CI/CD pipelines)
uv run scripts/count_tokens.py ../../coding/godoctor/SKILL.md --json

Authentication & Models:

Vertex AI ADC (Default): Automatically detects Application Default Credentials (gcloud auth application-default login) with model gemini-3.7-flash and location global.
Gemini Developer API: Set export GEMINI_API_KEY="..." to authenticate directly via Gemini API.
Offline Fallback: Automatically falls back to an offline ~4 chars/token heuristic if no network or credentials are available.

Stage 2: Description, Trigger & Tag Optimization

The frontmatter description is the primary text loaded by orchestrators at startup to determine activation. Craft every description against this 3-part blueprint:

[1. Concrete Definition & Scope] + [2. Architectural Superpower / Key Topics] + [3. Natural, Decisive Trigger]

Concrete Definition & Scope:
- State what the skill does in plain, direct English.
- Enumerate tangible topics, formats, and artifacts covered.
- Use universal mental models (e.g., "Divide to Conquer approach").
- Avoid narrating a play-by-play checklist in the description.
Key Architecture / Superpower:
- State the technical capability plainly (e.g., "uses parallel subagents to ensure context isolation").
- Explain why the approach matters for quality and reliability.
- Use open, illustrative examples (e.g., "connected channels (such as LinkedIn, X/Twitter, Bluesky, and others)").
- Do not waste tokens explaining internal algorithms or private code plumbing (e.g., AST parsing, regex, SQLite internals).
Decisive Triggers:
- Include explicit domain terms and tool names.
- 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").

Trigger Discipline (The Anti-Pushy Rule)

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.
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.

Tag Taxonomy Guidelines

Choose 3 to 6 high-level domain anchors for search indices.
Do NOT repeat the skill name as a tag: The name is already indexed. Repeating it wastes tag budget.
Avoid generic noise tags: Words like cli or hierarchy convey minimal context. Use domain-specific anchors like management or structure.
Omit implementation details: Skip low-level tags (sqlite) when high-level intent tags (sql, analytics) are present.
Include brand/ecosystem anchors when scoped specifically (e.g., google for Google-specific standards).

Stage 3: Core Principles for Skill Body Design

Every skill body must adhere to these 6 instructional standards:

Teach Practices, Not Passive Declarations:
- Provide concrete, repeatable workflows, architectural patterns, commands, and debugging steps.
- Focus on what the agent should do, check, and produce, rather than reciting encyclopedia definitions.
Readability & Clear Scannability:
- Maintain clear sentence structure and high scannability (aim for Fog Index ~12–15 with leeway for technical syntax).
- Avoid dense walls of text; organize multi-step procedures into structured checklists (- [ ] Step 1...).
Zero Marketing, Buzzwords & Fake Qualifiers:
- Never use marketing buzzwords ("vibrant", "cutting-edge", "blazing-fast", "world-class", "bespoke", "game-changing").
- Never use fake technical qualifiers ("high signal SQLite WAL Engine" ❌). State capabilities plainly ("SQLite database" ✅).
Usability Over Implementation Plumbing:
- Emphasize the interface the agent interacts with (e.g., SQLite tells the agent to query via SQL).
- Omit internal runtime trivia that does not affect agent intera
