Agent Skill Reviewer
Instructions
When the user asks you to review an Agent Skill, follow these steps to ensure the skill complies with the best practices.
1. Identify the Target
Determine the directory path of the Agent Skill to be reviewed. Read the directory structure and the content of the SKILL.md file.
2. Analyze Directory Structure
Check if the project follows the production-grade directory structure:
- Directory Name: Must use
kebab-case. - Core File: Ensure the core instruction file is named exactly
SKILL.md(uppercase). - Separation of Concerns: Look for proper subdirectories (e.g.,
scripts/for executable code,references/for docs,assets/for static files).
3. Review Naming Conventions
- Role-based Naming: Check if the skill name uses a Noun/Doer format instead of a Verb/Action format (e.g.,
agent-skill-reviewerinstead ofagent-skill-review).
4. Review Frontmatter (Metadata Layer)
- Read the YAML frontmatter of
SKILL.md. - Name: Verify that the
namefield is present and matches the directory name. - Description Formula: Verify that the
descriptionfollows the golden formula:[Function] + [Trigger Scenario] + [Keywords]. It must be specific enough for the LLM to reason about when to trigger the skill.
5. Review Instructions (Core Logic Layer)
- Clarity: Check if the instructions are clear, step-by-step, and easy for an LLM to follow.
- State & Concurrency: Ensure the skill does not attempt to handle highly concurrent parallel tasks within a single conversation thread, as skills modify the context state.
- Offloading: Ensure no complex logic is hardcoded in Markdown if it can be offloaded to an external tool or script (e.g., in
scripts/). - Progressive Disclosure: Verify that detailed supplementary knowledge is placed in
references/rather than cluttering the mainSKILL.md.
6. Report Findings
Present a structured review report to the user using the following format:
- Directory Structure & Naming: Pass/Fail with details.
- Frontmatter: Pass/Fail with details.
- Instructions: Pass/Fail with details.
- Recommendations: Provide actionable recommendations for any violations of best practices.
