When to Use This Skill

• User asks to refine a specific MCP skill description.
• User asks to refine all MCP skills for a server.
• User asks to refine all MCP skills under dev-swarm/mcp-skills.

Instructions

Follow these steps in order:

Step 1: Identify Scope

Clarify whether the request targets:

• One MCP skill
• All MCP skills for a specific server
• All MCP skills under dev-swarm/mcp-skills/

Step 2: Inspect Current Descriptions

For each target dev-swarm/mcp-skills/**/SKILL.md:

• Read the file to understand the content
• Read the YAML frontmatter description and verify description field if it follows the agent skill specification:
  • Explains what the tool does
  • Explains when to use it
  • Includes relevant keywords
  • 1-1024 characters, concise and single-paragraph

Step 3: Refine Descriptions

If the description is too long, too short, or missing context for AI agent to pick it up:

• Rewrite it to be concise and precise
• Preserve any critical constraints (e.g., required prerequisites)
• Avoid multi-line or overly verbose wording If the description already meets the specification, do not modify the skill or add an override entry.

Example:

The orignal description for playwright-browser-navigate is "Navigate to a URL", which is hard for AI Agent to pick up based on the context, We need to refine it as "To open a http url, open a web page, open web browser, or navigate the current page in the web browser to a new URL".

Step 4: Record Overrides

Update or create dev-swarm/mcp_descriptions.yaml with:

skill-name: >
  Updated description

Example:

playwright-browser-navigate: >
  To open a http url, open a web page, open web browser, or navigate the current page in the web browser to a new URL

• Use the skill name from the name: field in the SKILL.md frontmatter.
• Add or update entries for every refined description.

Step 5: Save Changes

Apply edits to the relevant SKILL.md files and ensure the JSON file is valid.

Expected Output

• Updated MCP skill descriptions in dev-swarm/mcp-skills/**/SKILL.md
• dev-swarm/mcp_descriptions.yaml containing the refined descriptions
