Quality

Content

96%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.

The content is an exemplar of actionable, token-efficient skill writing: concrete commands, explicit guardrails, a validated workflow with feedback loops, and a clear report format. Its only structural note is that the always-active principles block could be split into a reference file at this length.

DimensionReasoningScore

Conciseness

The body is dense project-specific policy with zero concept explanations or padding — every element (failure taxonomy with symptoms, fix rules, command examples, report template) earns its tokens and assumes Claude's competence. Not 4: there is no over-explanation left to trim.

5 / 5

Actionability

Guidance is fully executable: concrete commands ("yarn playwright test --reporter=line -g 'transfer'"), specific fix patterns (replace waitForTimeout with getByRole, expect() web-first assertions), a failure-parsing table, and a ready-to-use report template, with fallbacks for project-specific setups.

5 / 5

Workflow Clarity

The five-step workflow (discover → run → categorize → fix by category → re-run and report) has explicit validation checkpoints: a unit-test gate before bug fixes are complete, a full suite re-run after fixes, and escalation of unverified failures to the user — a clear feedback loop.

5 / 5

Progressive Disclosure

The single-file skill is well-sectioned (always-active principles vs. explicit-run workflow) with no bundle files to navigate, but at ~135 lines the always-active principles and fix rules could plausibly live in a one-level-deep reference file, and there are no well-signaled references to reward.

Description

88%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 that clearly and concisely states what the skill does, when to use it, and its safety boundary in third-person voice. Its only weaknesses are a slightly generic "debugging test failures" trigger and missing natural synonyms like "end-to-end" or "Playwright".

DimensionReasoningScore

Specificity

The description lists four concrete actions ("Run e2e tests, fix flake and outdated tests, identify bugs against spec") plus a behavior boundary ("Never changes source code logic or API without spec backing"), giving comprehensive coverage of the skill's actions rather than minor gaps.

5 / 5

Completeness

It explicitly answers both what ("Run e2e tests, fix flake and outdated tests, identify bugs against spec") and when ("Use when running e2e tests, debugging test failures, or fixing flaky tests") with concrete trigger phrases, matching the top anchor exactly.

5 / 5

Trigger Term Quality

Natural phrases users would say are present ("running e2e tests", "debugging test failures", "fixing flaky tests"), but common synonyms and variations like "end-to-end tests", "Playwright", or "integration tests" are missing.

4 / 5

Distinctiveness Conflict Risk

"e2e tests" and "flaky tests" carve out a clear niche, but the generic trigger "debugging test failures" could overlap with a unit-testing or general debugging skill, leaving minor conflict risk rather than minimal.
