Quality

Content

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A compact, instruction-only skill that is highly actionable with explicit mappings and a verification checkpoint. It respects token budget and is well organized for a single-purpose task with no bundle files.

DimensionReasoningScore

Conciseness

Lean and efficient with no concept explanation Claude already knows; every line is an actionable instruction and every token earns its place.

3 / 3

Actionability

Provides concrete, copy-paste-ready guidance — exact file paths, explicit tracker-to-field mappings (Chromium→Chrome, WebKit→Safari, Mozilla→Firefox), a known reporter mapping, and precise Fixed? values. Per the instruction-only scoring note, absence of code is not penalized when guidance is this actionable.

3 / 3

Workflow Clarity

A clear 5-step numbered sequence closes with an explicit Verification section ('inspect the diff and confirm the row has the right URL, product, filed-by value, and fixed state'), giving a validation checkpoint appropriate to this single-row edit.

3 / 3

Progressive Disclosure

A simple skill under 50 lines with no external references, organized into clear Workflow and Verification sections; per the rubric note, well-organized sections suffice for a 3 here.

Description

100%

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 tight, third-person description that states concrete actions, explicit triggers, and a clearly bounded niche. It answers what and when without padding or over-claiming.

DimensionReasoningScore

Specificity

Names multiple concrete actions — 'Add a browser WebCodecs bug to the... docs page' and 'look up the issue title, filing date, reporter, and resolution state before editing the MDX table' — matching the anchor for listing several specific actions.

3 / 3

Completeness

Explicitly answers both what ('Add a browser WebCodecs bug to the... docs page') and when ('Use when given a Chromium, WebKit, or Firefox issue URL...'), with an explicit 'Use when' trigger clause.

3 / 3

Trigger Term Quality

Uses natural trigger terms a user would say — 'Chromium, WebKit, or Firefox issue URL' and 'WebCodecs bug' — giving good coverage of how the request would actually be phrased, not jargon.

3 / 3

Distinctiveness Conflict Risk

The niche is highly specific — tracking browser WebCodecs issues on the Remotion Mediabunny docs page — with distinct triggers unlikely to fire for unrelated skills.
