vastai-host-mcp: Skill for Claude Code

name: skill-writer description: >- When the user requests to create, update, or refine a GitHub Copilot skill, generate or revise a complete SKILL.md file that strictly adheres to the official format, validation rules, and community best practices.

Skill Writer

Generate or update SKILL.md files for GitHub Copilot coding agents, ensuring precise activation, concise expert-level guidance, and full compliance with repository standards.

When to Activate

• User explicitly asks to create or update a skill for a specific issue, topic or task.
• User requests to update, improve, or refactor an existing SKILL.md.
• User provides new rules, examples, or feedback intended to guide skill authoring.
• Capture Agent Insights: When the agent struggles with a recurring task, encounters repeated failures, or discovers an effective new solution/workaround not already documented, update the relevant existing skill (or create a new one) to incorporate the insight, ensuring future activations handle the case more efficiently.

Core Process

1. Infer a unique, descriptive name in lowercase-hyphenated format that will exactly match the intended folder name.

2. Write a single, highly precise description sentence that captures exact activation triggers without overlap.

3. Validate that the YAML frontmatter follows all repository-defined schema, linting, and validation rules (e.g., required fields, no extra keys, correct formatting).

4. Structure the file exactly as:

   • First line: <!-- markdownlint-disable MD003 MD022 MD026 MD041 -->
   • YAML frontmatter block
   • Pure Markdown body with minimal, value-adding sections only

5. Write dense, imperative, expert-level instructions assuming ninja proficiency; skip basics, favor one-liners, pack maximum depth.

6. Design for fully autonomous agent execution: include self-contained loops, error recovery, verification steps; avoid any user confirmation except safety-critical cases.
