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 excellent, fully executable runbook: a clear labeled-PR decision tree with validation checkpoints, failure feedback, and complete gh/curl commands. The only notable flaw is minor redundancy between the Requirements/Monitor progress sections and earlier content.

Suggestions

Remove the duplicated "The canary workflow is publish-canary.yml" line from Requirements — it is already stated in the intro.

Trim or merge the Monitor progress section, since its `gh run list` command duplicates the listing already shown in path B.

Consider stating explicitly in path A how to distinguish "Not run" from an in-progress follow-up (e.g., re-check after a wait), to make the recovery loop fully self-contained.

DimensionReasoningScore

Conciseness

The body is lean and almost entirely repo-specific (label semantics, fork behavior, SHA extraction), assuming Claude's competence with no concept tutorials. Minor trimming is possible: "publish-canary.yml" is restated in Requirements, and the Monitor progress `gh run list` duplicates path B's listing, so it does not fully meet anchor 5's "every token earns its place".

4 / 5

Actionability

Every block is copy-paste-ready executable bash (`git rev-parse --short=7`, `curl -I`, full `gh pr list`/`gh workflow run`/`gh run watch` commands) with variables assigned in-block, and even the tricky RUN_SHA extraction is a real command. Anchor 4 is ruled out because there is no pseudocode or missing detail — edge cases are covered.

5 / 5

Workflow Clarity

The A/B/C decision flow gives an explicit if-then sequence with a pre-check validation (HTTP 200 = canary exists), a watch checkpoint (`gh run watch`), and post-run status interpretation (Released/Failed/Not run) whose failure branch links to the workflow run. Anchor 4 is ruled out because validation checkpoints and error-recovery feedback are both explicit, not implicit.

5 / 5

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ absent) and nothing in the body needs extraction to a separate file; sections are clearly headed and each is used by the decision flow. Per the no-external-references case, well-organized sections suffice for the top anchor.

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: third person, concise, with a clear what and an explicit Use-when clause containing concrete triggers. Its only weakness is slightly thin action coverage and a few missing natural synonyms relative to a maximally comprehensive trigger list.

DimensionReasoningScore

Specificity

"Finds or publishes a pkg.pr.new canary release for a Storybook branch" names the domain (pkg.pr.new, Storybook canary) and two concrete actions (find, publish) that fully cover the skill's scope. It falls short of anchor 5 only because two verbs is thin relative to the multi-step finding/publishing/monitoring the body actually performs.

4 / 5

Completeness

It explicitly answers both what ("Finds or publishes a pkg.pr.new canary release for a Storybook branch") and when ("Use when the user wants the canary package specifier for a branch or needs to trigger the canary workflow manually") with concrete trigger phrases. Anchor 4 is ruled out because the when-clause is explicit and specific, not merely present.

5 / 5

Trigger Term Quality

"canary release", "pkg.pr.new", "canary package specifier", and "trigger the canary workflow manually" are the natural phrases a user would say for this need. Not anchor 5 because common variations like "install the canary", "pr.new", or "unreleased build" are absent.

4 / 5

Distinctiveness Conflict Risk

The pkg.pr.new/Storybook canary niche is highly specific with distinct triggers ("canary package specifier", "trigger the canary workflow"), so overlap with other skills is minimal. It is not a 4 because no closely-related-skill overlap is evident.
