repo-health

The repository-cornerstone skill. Owns the canon for the community-health files that bootstrap any code repository:

• README.md — the front door (Standard Readme spec).
• LICENSE — the legal contract (routed to choosealicense.com; doc-master does not pick).
• CONTRIBUTING.md — how external contributors propose changes.
• CODE_OF_CONDUCT.md — behavioral norms (Contributor Covenant 3.0 default; 2.1 fallback).
• SECURITY.md — vulnerability reporting policy.
• SUPPORT.md — where users go for help (often optional for small repos).
• .github/ templates — issue / PR / CODEOWNERS / FUNDING / CITATION.
• REUSE 3.3 + SPDX — per-file copyright and license metadata.

Each cornerstone has a reference file with the structure, common failure modes, and routing notes. This SKILL.md is the lean entry point — load the references on demand.
