Conciseness

The body is dense and imperative with detail properly delegated to references, but the skill-context loading/precedence rules are explained twice (the opening "Shared project skill-context" section and again in Step 0), the Angie-over-Nginx preference and its full documentation URL are repeated (Step 1.3 and Step 2.5), and the Section 2.1/2.2 tables restate facts Claude already knows (express → port 3000, django → gunicorn, golang alpine base images). This fits 'mostly efficient but includes some unnecessary explanation or could be tightened' better than the score-4 anchor, whose over-explanation would be only minor.

Actionability

Guidance is largely executable: exact Glob/Grep patterns ("Glob: cmd/*/main.go", "Grep: postgres|postgresql|pg_|mysql"), concrete AskUserQuestion blocks with options, and precise hardening values (user: "1001:1001", tmpfs "noexec,nosuid,size=100m", "127.0.0.1:5432:5432", example tags like golang:1.24-alpine). The gaps that keep it from 5: Step 3 instructs reading template files (templates/dockerfile-<language>, templates/compose-base.yml, templates/deploy.sh, etc.) that do not exist in the bundle, reference paths use inconsistent prefixes, and Step 2.3 defers to an external skill ("Same detection as /aif-build-automation Step 2.2").

Workflow Clarity

A clear Step 0–9 sequence with a mode-routing table, three explicit decision paths (A/B/C) and an --audit override, and named per-step state (PROJECT_PROFILE, USER_INFRA_CHOICES, EXISTING_CONTENT). Validation is explicit and layered: the "Quality Checks (Before Writing)" correctness and over-engineering checklists with "Remove anything that fails... before writing", the always-run Step 7 security checklist with "If any checks fail → offer to fix immediately", and skill-context enforcement ("If any rule is violated — fix the output before presenting it to the user"), plus audit-mode feedback loops (fix all / fix critical only). This matches the score-5 anchor with checklists and error-recovery loops.

Progressive Disclosure

Against the actual bundle: all 9 files in references/ are real, one level deep, and well-signaled — two are explicitly conditionally gated (ANGIE-ACME.md "read when generating or auditing Angie HTTPS/ACME configuration", COMPOSE-LIFECYCLE-HOOKS.md "read when a production Compose service runs non-root but needs named-volume ownership fixes") and the rest are tied to specific steps. However, Step 3 and Step 8 reference a templates/ directory (dockerfile-go/node/python/php, compose-base.yml, compose-override-dev.yml, compose-production.yml, dockerignore, six deploy scripts) that does not exist in the bundle — a dangling reference the generation workflow depends on — and paths are inconsistent ("skills/dockerize/references/BEST-PRACTICES.md" vs "references/COMPOSE-PATTERNS.md" for the same directory). The broken template navigation plus mixed path conventions pull this below the score-4 'minor organization gaps' anchor.

Specificity

The description enumerates every concrete deliverable — "Dockerfile (multi-stage dev/prod), compose.yml, compose.override.yml (dev), compose.production.yml (hardened), and .dockerignore" — plus "Includes production security audit", giving comprehensive, specific coverage of actions in third-person voice. It clearly matches the 'multiple specific concrete actions; comprehensive coverage' anchor rather than the score-4 anchor, which allows coverage gaps.

Completeness

Both parts are explicit: the what ("Analyze project and generate Docker configuration: Dockerfile..., .dockerignore. Includes production security audit") and the when ("Use when user says 'dockerize', 'add docker', 'docker compose', 'containerize', or 'setup docker'"). This exactly matches the anchor requiring concrete trigger phrases for both what and when.

Trigger Term Quality

Triggers "dockerize", "add docker", "docker compose", "containerize", or "setup docker" cover the natural synonyms and verb phrases a user would actually say, with "Dockerfile" also appearing in the what-clause. Coverage is comprehensive for the domain rather than merely 'good with a few missing', fitting the score-5 anchor.

Distinctiveness Conflict Risk

The Docker-configuration-generation niche is clear and triggers are domain-specific, but "docker compose" alone could also fire on a user wanting to run or debug an existing stack rather than generate config, and the body references the closely related `/aif-build-automation` skill for Docker targets. This is 'mostly distinct; minor overlap risk with closely related skills' rather than the minimal-conflict score-5 anchor.
