Skill Metadata Maintainer

Maintain metadata in exactly one target skill.

This skill exists to initialize or update the metadata object inside one SKILL.md file while following repository rules from CONTRIBUTING.md.

Non-Negotiable Safety Rules

• You MUST operate on exactly one target skill per request.
• You MUST require the user to specify a unique target, such as the skill name, the skill directory path, or the SKILL.md path.
• You MUST NOT infer a bulk target such as "all skills", "the whole repo", or "every missing file" from ambiguous wording.
• If the request does not identify a single skill unambiguously, you MUST stop and ask the user to specify the exact target skill.
• Before modifying anything, you MUST read the existing SKILL.md and inspect the current metadata values if present.
• If any target metadata field already has a value and your change would add, replace, or normalize that value, you MUST explicitly show the user what exists now and ask for confirmation before writing.
• You MUST NOT silently overwrite existing metadata values.
