Quality

Content

92%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.

An exemplary instruction-only skill body: fully executable commands, exact file paths, explicit validation gates with error-recovery guidance, and tight project-specific content. The only improvement area is isolating time-sensitive version history (Playwright revision change, Chrome 149+ feature notes) into a clearly marked section.

DimensionReasoningScore

Conciseness

Nearly every line is non-inferable project-specific detail (account ID, layer names, env-var persistence gotcha, tarball pipeline), but inline time-sensitive markers like "such as 157.0.8080.0", "Chrome 149+", and "Default downloads no longer use a Playwright revision" sit outside any old-patterns/deprecated section, so minor trimming is possible.

4 / 5

Actionability

Copy-paste-ready commands throughout: `aws sts get-caller-identity`, `eval "$(aws configure export-credentials --format env)"`, `bun src/admin/make-layer-public.ts --region=eu-central-1`, `curl -sI`, `./run.sh`, plus exact file paths and per-line edit instructions covering the common cases.

5 / 5

Workflow Clarity

A clear sequence (AWS setup → publish layers → update hosted layers → update Chrome references → Docker verification) with explicit validation checkpoints ("Verify the output prints a LayerArn and Version for each of the 5 layers", "Continue only when all return HTTP 200"), failure-mode recovery guidance for the html-in-canvas mismatch, and a final gate before full rollout.

5 / 5

Progressive Disclosure

The body is under 50 lines with no need for external references, organized into four well-labeled sections (AWS setup, hosted layers, Chrome references, Docker verification); per the simple-skill guidance this warrants a top score with well-organized sections alone.

Description

87%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 strong description: concrete actions, an explicit 'Use when' trigger, and a highly distinctive niche. The only weakness is slightly incomplete keyword coverage and unmentioned scope items like docs updates and Docker verification.

Suggestions

Add natural synonyms to the trigger clause, e.g. 'Use when updating or rolling out Chrome/headless-shell versions to a new region'.

Mention the full scope briefly (updating docs version tables and running Docker verification) so the description covers everything the skill does.

DimensionReasoningScore

Specificity

"Publish Remotion Lambda Chrome binaries to the eu-central-1 test region and update hosted layer and Chrome version references" lists several specific actions with a named region, but omits parts of the scope (docs updates, Docker verification), matching the 'several specific actions; minor gaps' anchor rather than comprehensive coverage.

4 / 5

Completeness

It explicitly answers both what ("Publish Remotion Lambda Chrome binaries... and update hosted layer and Chrome version references") and when ("Use when updating Chrome binaries before full regional rollout") with a concrete trigger phrase, matching the top anchor exactly.

5 / 5

Trigger Term Quality

"Use when updating Chrome binaries before full regional rollout" plus "test region" give good natural keyword coverage, but common synonyms users might say ("bump Chrome version", "headless shell", "publish layers") are missing, fitting the 'good coverage; a few natural terms missing' anchor.

4 / 5

Distinctiveness Conflict Risk

The combination of "Remotion Lambda Chrome binaries" and "eu-central-1" is a clear niche with distinct triggers; minimal conflict risk with any other skill.
