Audit Skill

Overview

Detects drift between a skill and its current source code and writes a severity-graded drift report with AST-backed findings and remediation suggestions; analysis depth follows the forge tier (Quick/Forge/Forge+/Deep). Stack skills: a compose-mode stack checks its constituents' freshness by metadata hash; a code-mode stack is diffed library by library. A docs-only skill is audited by its documents' hashes; a skill with no provenance map has no baseline, so step 1 stops it.

Conventions

• Bare paths (e.g. references/<name>.md) resolve from the skill root.
• Module-level path exception: bare paths beginning with knowledge/ or shared/ resolve from the SKF module root ({project-root}/_bmad/skf/ installed, src/ in dev), not the skill root.
• Sibling skills: a path that names another SKF skill's folder (skf-<name>/...) resolves from the SKF module root, and that skill must be installed with this one.
• scripts/ holds render-drift-tables.py, which steps 3, 5 and 6 run to print their drift tables.
• {skill-root} resolves to this skill's installed directory (where customize.toml lives, if present).
• {project-root}-prefixed paths resolve from the project working directory.
• {skill-name} resolves to the skill directory's basename.
• Cross-skill data coupling: re-index.md loads extraction-patterns.md and tier-degradation-rules.md from skf-create-skill/references/.
