From the source SKILL.md

This skill audits the health of every generated compatibility target for the ycc plugin — Claude, Cursor, Codex, and opencode — and produces a structured, per-target triage report. It detects bundle drift between the ycc/ source tree and the generated bundles, validates install assumptions (path conventions, shebang lines, executable bits), and surfaces feature-capability gaps using the shared capability matrix. It never bumps versions, never commits, and never modifies any file.

What this skill does
