Quality

Content

87%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A tight, highly actionable single-purpose skill with excellent conciseness and structure. The only real gap is the absence of a validation/verification step after the destructive production launch, which caps workflow clarity.

Suggestions

Add a post-launch verification step to the production workflow (e.g. `docker ps` to confirm the container is running and a curl/health check on port 20211) to close the validation gap for the destructive --force-recreate operation.

Clarify that the pkill step is destructive and should be confirmed/verified (e.g. checking no lingering php-fpm83/nginx processes remain) before proceeding to the build.

DimensionReasoningScore

Conciseness

Lean and efficient with no padding; every line adds non-obvious value (rebuild triggers, build-time estimates, port assignments) and assumes Claude's competence, matching the top anchor.

5 / 5

Actionability

Fully executable, copy-paste-ready commands (docker buildx build, docker compose up, pkill) cover the common cases, matching the top anchor.

5 / 5

Workflow Clarity

A sequence and pre-launch checklist are present, but destructive operations (pkill of services, docker compose --force-recreate) lack any validation or verification step, so the destructive-operation cap of 3 applies.

3 / 5

Progressive Disclosure

Under 50 lines, single-purpose, with no need for external references and well-organized sections, qualifying for the top anchor under the simple-skill exception.

Description

78%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A concise, well-formed description that answers both what and when with concrete trigger phrases. Slightly limited action specificity and minor overlap risk with generic Docker skills keep it just below the top tier.

DimensionReasoningScore

Specificity

Names the Docker domain and two concrete actions ("Build Docker images for testing or production", "launch production container"), but coverage is limited to build/launch rather than a comprehensive action set, matching the anchor for 1-2 concrete actions.

3 / 5

Completeness

Clearly states what the skill does ("Build Docker images for testing or production") and explicitly answers when with an "Use this when asked to..." clause listing concrete triggers, matching the top anchor.

5 / 5

Trigger Term Quality

Includes several natural phrases users would say ("build container", "build image", "docker build", "build test image", "launch production container"), with only minor synonyms missing, fitting good-but-not-comprehensive keyword coverage.

4 / 5

Distinctiveness Conflict Risk

The test-image vs production-launch distinction gives it a fairly distinct niche, though the description alone (without the netalertx project name) retains minor overlap risk with generic Docker build skills.
