devtools-verification

MANDATORY: Activate this skill ANY TIME you need to build the project, run tests, or verify code health in DevTools. You MUST use this skill before executing commands like npm test, npm run build, autoninja, or linters, as it contains critical, repository-specific instructions on how to correctly format these commands, filter test runs, and interpret failures.

Quality

Content

80%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 concise, highly actionable verification skill with well-organized sections and copy-paste commands. Its gap is workflow clarity: it lacks explicit failure-handling feedback loops and the failure-interpretation guidance promised by the description.

Suggestions

Add a short feedback loop for failures, e.g. 'If tests/build fail, read the error, fix the cause, and re-run before proceeding.'

Add a checkpoint for the batch lint auto-fix, e.g. review the applied changes with `git diff` before committing, since `npm run lint` modifies files automatically.

Trim obvious Best practices lines ('Run tests often', 'Periodically build') or fold them into the actionable command sections to tighten token efficiency.

DimensionReasoningScore

Conciseness

Mostly lean and repo-specific, but the Best practices section leans on slightly obvious guidance ("Run tests often to verify your changes", "Periodically build to check for errors") that could be trimmed.

4 / 5

Actionability

Provides copy-paste-ready commands with concrete examples across the common cases: `npm run test -- <FILEPATH>`, directory runs, `autoninja -C out/Default`, `npm run lint`, and `git cl presubmit -u`.

5 / 5

Workflow Clarity

Sections are clear and single-purpose, but there is no feedback loop (test/build fails → inspect → fix → re-run) and the description's promise to "interpret failures" is not delivered in the body; the batch lint auto-fix also lacks a review checkpoint.

3 / 5

Progressive Disclosure

Under 50 lines with no external references needed; content is cleanly organized into well-labeled sections (Testing, Building & compiling, Linting, Best practices), satisfying the simple-skill exception.

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, trigger-rich description that clearly states both what it does and when to use it, with concrete DevTools-specific commands that make it highly distinct. Its main weakness is pervasive second-person/mandatory phrasing where a third-person voice would be cleaner.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities ("format these commands, filter test runs, and interpret failures" plus build/test), which on merit is comprehensive; reduced by 1 for heavy second-person voice ("You MUST use this skill", "you need to build").

4 / 5

Completeness

Explicitly answers what ("repository-specific instructions on how to correctly format these commands, filter test runs, and interpret failures") and when ("ANY TIME you need to build the project, run tests..." with concrete trigger commands).

5 / 5

Trigger Term Quality

Strong natural trigger phrases ("build the project, run tests, or verify code health") plus concrete commands (npm test, npm run build, autoninja, linters); a few synonyms are absent so it is not a full 5.

4 / 5

Distinctiveness Conflict Risk

Scoped to DevTools with repo-specific tooling (autoninja, npm run build, git cl presubmit), giving it a clear niche with minimal overlap risk against generic skills.
