Conciseness

Mostly efficient and free of explaining-known-concepts, but systematic redundancy could be tightened: the same handoff routing appears in three tables (ownership boundary, Layer-1 wizard, intent classification), and the token/offline rule ("zizmor reads GH_TOKEN, GITHUB_TOKEN or ZIZMOR_GITHUB_TOKEN from the environment itself") and the pinning-policy recommendation are each restated in 3-4 sections. The duplication goes beyond the 4 anchor's "minor instances that could be trimmed", fitting the 3 anchor's "could be tightened".

Actionability

Fully copy-paste ready: exact CLI invocations ("zizmor --strict-collection --offline .", "uvx zizmor@1.29.0", the git dirty-tree guard one-liner), complete YAML for all three pinning-policy shapes and the pre-commit hook, and exact suppression syntax ("# zizmor: ignore[id] <reason>") and triage outcome mechanisms. Not 4: there are no gaps in executable coverage across all eight modes.

Workflow Clarity

Clear mode dispatch and a three-layer wizard with explicit validation checkpoints and feedback loops for the file-editing (fix) mode: refuse on a dirty tree ("git status --porcelain | grep -q . && { echo 'commit or stash first'; exit 1; }"), show the diff, "run the audit again and report what remains", plus rollback ("git checkout -- ."). Validation is present for the in-place-editing operation, so the destructive/batch cap does not apply; not 4 because every checkpoint for every mode is explicit, including the SARIF exit-code trap.

Progressive Disclosure

The body's load-bearing reference is dangling: it opens with "Read `references/zizmor.md` before responding" and cites named sections of it ("Triage decision tree", "Repository patterns", "Worked baseline config", "CI integration", the 41-audit catalogue), but no references/ directory exists anywhere in the bundle, so the catalogue, decision tree, and CI templates the skill depends on are unreachable. Combined with a ~390-line body, this matches the 2 anchor (minimal effective structure / referenced material not actually available) rather than the 3 anchor's "references present".

Specificity

Lists multiple specific concrete actions with comprehensive coverage: "Audit GitHub Actions workflows, composite actions, Dependabot configs, and pre-commit configs for security findings using zizmor — template injection, credential persistence, unpinned uses, over-broad permissions, impostor commits" plus "Covers local CLI, auto-fix, zizmor.yml policy, severity-based CI gates, SARIF upload, and pre-commit." The what is concrete at every level (inputs, finding types, capabilities), so it matches the 5 anchor rather than the 4 anchor's "minor gaps in coverage".

Completeness

Explicitly answers both questions: what ("Audit GitHub Actions workflows ... for security findings using zizmor — template injection, credential persistence, unpinned uses, over-broad permissions, impostor commits") and when ("Use when asked to 'audit my workflows', 'run zizmor', ...") with concrete trigger phrases. Both clauses are explicit, matching the 5 anchor.

Trigger Term Quality

Comprehensive natural phrasings a user would actually say: "audit my workflows", "run zizmor", "is this workflow safe", "check for template injection", "pin my actions", "set up a zizmor CI gate", including the tool name itself, config filename (zizmor.yml), and finding-level terms. Coverage includes synonyms at both the tool level and the task level, fitting the 5 anchor.

Distinctiveness Conflict Risk

Clear niche (GitHub Actions security auditing via zizmor) with distinct triggers, and it actively reduces conflict risk with explicit negative routing: "Workflow syntax and shell errors → /platform-skills:github-actions (actionlint). IaC misconfig → /platform-skills:checkov. Image and dependency CVEs → /platform-skills:trivy. Keeping SHA pins fresh → /platform-skills:renovate." Minimal overlap risk.
