Conciseness

The body is dense with tables, globs, greps, and checklists and explains nothing Claude already knows, but it contains noticeable repetition: the Angie-over-Nginx preference (with URL) appears three times (Step 1.3, Step 2.5, Step 4.2), and the ~20-line skill-context section repeats its precedence rule four ways ('MANDATORY', 'CRITICAL', 'Enforcement'). This fits 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than the 4 anchor's 'minor instances'.

Actionability

Guidance is highly concrete — exact Glob/Grep patterns, framework-to-port/dev-command tables, literal hardening values ('user: "1001:1001"', 'tmpfs ... noexec,nosuid,size=100m', '127.0.0.1:5432:5432') and per-checklist quality gates. It stops short of 5 because the Dockerfile and deploy-script generation leans on 'Read skills/dockerize/templates/...' files that are not present in the bundle, and Step 2.3 defers to an external skill ('Same detection as /aif-build-automation Step 2.2'), leaving minor execution gaps.

Workflow Clarity

The nine-step sequence is explicit with mode-selection logic (Path A/B/C, --audit override), pre-write quality checks, an over-engineering gate ('Remove anything that fails ... before writing'), a mandatory security checklist with a score, and feedback loops ('If any checks fail → offer to fix immediately'; 'If any rule is violated — fix the output before presenting it'). This matches the 5 anchor: clear sequence, explicit validation, error-recovery loops, and checklists.

Progressive Disclosure

The nine references/ files that exist are well signaled with when-to-read conditions, but roughly fourteen referenced paths ('templates/dockerfile-go', 'templates/compose-base.yml', 'templates/deploy.sh', etc.) do not exist anywhere in the bundle, and path prefixes are inconsistent ('skills/dockerize/references/...' vs 'references/...'). Broken navigation to a large portion of referenced content exceeds the 4 anchor's 'minor organization gaps' and fits 'some structure but could be better organized'.

Specificity

The description enumerates every concrete artifact with distinguishing detail — 'Dockerfile (multi-stage dev/prod)', 'compose.override.yml (dev)', 'compose.production.yml (hardened)', '.dockerignore' — plus 'Includes production security audit'. This matches the anchor 'lists multiple specific concrete actions; comprehensive coverage'; it is not score 4 because coverage of the skill's outputs is complete rather than having minor gaps.

Completeness

It explicitly answers both questions: the 'what' is a detailed artifact list and the 'when' is a concrete 'Use when user says...' clause with literal trigger phrases. This matches the 5 anchor exactly; the 4 anchor ('when could be more explicit') does not apply since trigger guidance is fully explicit.

Trigger Term Quality

Trigger phrases 'dockerize', 'add docker', 'docker compose', 'containerize', or 'setup docker' are natural terms users would actually say, giving good keyword coverage. It falls short of the 5 anchor ('comprehensive coverage of natural terms including synonyms and file extensions') because common variations like 'dockerfile', 'dockerization', or 'docker setup' phrasing are missing.

Distinctiveness Conflict Risk

Docker/containerization is a clear niche with distinct, unambiguous triggers ('dockerize', 'docker compose', 'containerize'), matching 'clear niche with distinct triggers; minimal conflict risk'. It is not a 4 because no closely related skill would plausibly claim these triggers.
