# Claude standards audit ## Guards - Resolve the base ref first, per Diff baseline below, then scope the file list exactly as Step 1 does, fallback included. If no markdown files changed, stop: `✅ No markdown changes to audit.` A guard that reads bare local `main`, or that skips the unusable-baseline fallback, passes the skill clean on a branch it never read. - If `${CLAUDE_SKILL_DIR}/../../standards/markdown.md` is not present, stop: `❌ markdown.md standard not found. Reinstall the canon plugin.` Test the file rather than the directory, since a plugin cache built before a given file existed keeps the directory without ever receiving that file. - `markdown.md` is the one standard testable before the mapping runs, since its scope statement declares an attribute and every changed markdown file therefore maps to it. Every other standard is tested in Step 3, where the mapping has named which ones the run needs. ## Diff baseline Resolve the base ref once and reuse it in the guard and in Step 1: ```bash git merge-base HEAD origin/main 2>/dev/null || git merge-base HEAD main 2>/dev/null ``` Prefer `origin/main` over local `main`. On `main` itself the local ref resolves to HEAD, so every committed change drops out of the set and the audit passes clean rather than admitting it cannot see the files. The baseline is unusable in two cases: - No merge base resolves against either ref. - The base equals HEAD, whichever ref resolved it. Nothing is committed ahead of the base to comp
