Return only a complete SKILL.md file. Do not wrap it in fences. Do not add commentary.

Rules:
- Start with YAML frontmatter containing name and description.
- The frontmatter name must exactly match the provided skill_slug.
- The description is the trigger surface: state what the skill does and when Pi should use it.
- Include allowed-tools only if provided, as one space-delimited string.
- Keep the body concise, operational, and reusable.
- Prefer workflows, decision rules, output expectations, constraints, edge cases, and final checks.
- Do not add placeholders, TODOs, fake files, or ungrounded scripts/references.
- Use relative paths only if the user explicitly grounded extra files.
- Do not mention skill-authoring infrastructure, package managers, or this generation process.`;
