Conciseness

The body is efficient and assumes Claude's competence (no explanations of what CI or gh is), but the "Example Commands" section largely duplicates commands already shown in the workflow (gh pr view --json, gh run view --log-failed). This matches anchor 4 (minor trimmable redundancy) rather than 5 (every token earning its place).

Actionability

Concrete, mostly copy-paste-ready commands appear throughout ("GH_PAGER=cat gh pr view <branch-name> --json statusCheckRollup", "gh run view <run-id> --log-failed 2>&1 | grep -A 5 \"error:\""), with clear parsing targets. Minor gaps (the create_plan tool reference and placeholder values) keep it at anchor 4 rather than 5.

Workflow Clarity

A clearly sequenced 5-step workflow (verify PR, check CI status, extract logs, categorize errors, generate plan) with explicit conditional handling ("If no PR exists...", "If CI is still running..."). The skill is read-only diagnosis so the destructive/batch validation cap does not apply; it stays at 4 rather than 5 because there are no feedback loops for error recovery (e.g., what to do if log extraction fails or the run ID is missing).

Progressive Disclosure

No bundle files exist, and the ~110-line body is well organized into labeled sections with references to companion skills (fix-errors, create-pr) clearly signaled. It matches anchor 4 (good structure, minor organization gaps); the under-50-line simple-skill exception for a 5 does not apply, and sections like "Common CI Check Names" and "Example Commands" are modest inline reference material that could be split out.

Specificity

"pull logs, isolate the failing step, plan the fix" lists several concrete, specific actions in the CI domain, though coverage has minor gaps (e.g., no mention of categorizing errors or identifying which checks failed). This matches anchor 4 rather than 3 (more than 1-2 actions) and falls short of 5 (not comprehensive).

Completeness

The description clearly answers both questions: what ("Diagnose a failed CI run: pull logs, isolate the failing step, plan the fix") and when (explicit "Trigger: CI red, check the pipeline" clause, so the missing-trigger cap at 3 does not apply). It sits above anchor 4 because the trigger guidance is explicit, but below anchor 5 because the trigger phrases are terse and lack the concrete variation coverage of the 5-star example.

Trigger Term Quality

"Trigger: CI red, check the pipeline" provides some relevant natural keywords, but misses common variations users would say such as "build failed", "tests failing", "checks are red", or "pipeline broken". This fits anchor 3 (some relevant keywords, missing common variations) rather than 4, whose keyword coverage is broader.

Distinctiveness Conflict Risk

CI failure diagnosis is a distinct niche with triggers ("CI red", "check the pipeline") unlikely to fire for unrelated skills. Minor overlap risk remains with closely related build/fix skills, matching anchor 4 rather than 5.
