Conciseness

The body is a dense checklist where every bullet carries DevTools-specific knowledge Claude would not otherwise have — exact APIs ('CSSWorkspaceBinding.removeInstance()'), exact error strings ('Attempted to wrap … which is already wrapped'), and concrete wrong-pattern examples. No section explains general programming concepts, and no bullet can be cut without losing real guidance, matching the lean/efficient anchor.

Actionability

Guidance is fully concrete and executable: real commands ('git diff origin/main...HEAD', the curl URL pattern for Gerrit comments with the ')]}\'' strip note), exact cleanup calls, a routing table with specific file/symbol triggers for each specialized skill, and specific E2E label examples ('Show user agent shadow DOM' vs 'User agent shadow DOM'). Per the scoring notes, absence of code blocks is not penalized for an instruction-only checklist when the guidance is this actionable.

Workflow Clarity

The numbered sections give a clear review sequence (gather context → consult specialized skills → test correctness → hygiene → clarity → CL hygiene → write comments) with a real checkpoint ('Read the CL description first. Then check that the diff does what the description says, and nothing else'). It does not reach anchor 5 because validation is delegated by reference ('Presubmit, lint, and format pass. See `devtools-verification`') rather than given as explicit validate-and-recover steps inline; this is a review checklist, not a destructive/batch operation, so the workflow-clarity cap of 3 does not apply.

Progressive Disclosure

No bundle files exist, so structure is scored on the SKILL.md itself. The routing table is well-signaled, one-level-deep delegation to specialized skills, and sections are clearly navigable. It sits below anchor 5 because the detailed test-correctness patterns in sections 3–4 (roughly half the file) are candidates for a reference file, leaving SKILL.md as a tighter hub — a minor organization gap rather than the clean split of the top anchor.

Specificity

The description lists several concrete coverage areas — 'test correctness (tautological/vacuous tests, cleanup, leaks), code clarity, CL hygiene' — plus an explicit routing capability ('points to the specialized skills to consult for imports, UI, testing, strings, models, and verification'). It stops short of anchor 5 because body sections like context gathering and writing review comments are not mentioned, leaving minor gaps in coverage. The voice is third-person throughout the operative clauses ('Covers…', 'points to…'); the parenthetical '(your own before upload…)' is a possessive qualifier, not second-person framing, so no voice penalty is applied.

Completeness

Both 'what' (checklist covering test correctness, clarity, hygiene, and routing to specialized skills) and 'when' are explicit: 'Use when asked to review a CL, a diff, a patch, or to self-review before `git cl upload`.' This matches the anchor with concrete trigger phrases for both halves, so it is not the anchor below where 'when' is only weakly implied.

Trigger Term Quality

It includes the natural terms a DevTools contributor would actually say: 'review a CL, a diff, a patch', 'self-review', 'Gerrit', and the exact command trigger 'git cl upload'. CL/diff/patch cover the synonym space for a change, matching the comprehensive-synonyms anchor rather than the 'a few natural terms missing' anchor.

Distinctiveness Conflict Risk

The niche is sharply delimited by 'DevTools CLs', 'Gerrit', and 'git cl upload' — terms that no generic code-review or document skill would trigger on. Distinct triggers, minimal conflict risk, matching the clear-niche anchor.
