devtools-setting-migration

Workflow for splitting an existing SettingRegistration into a SettingDescriptor (placed in the lowest layer where used: core/, models/, or ui/settings/) and SettingUIDescriptor (registered in a higher-level -meta.ts file, outside of core/ and models/).

Quality

Content

85%

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

A thorough, highly actionable migration guide with executable code, a well-sequenced workflow, and explicit validation. Its main weakness is redundancy — the panel-placement rule and worked examples repeat content already covered in the workflow steps — which keeps conciseness from the top level.

Suggestions

Consolidate the repeated 'descriptors must not go in panels/' rule into one authoritative statement and reference it from the other sections instead of restating it.

Trim the two worked examples to only the delta from the workflow (e.g. the panel UI case's distinct ui/settings placement) rather than re-showing near-identical descriptor and registration code.

DimensionReasoningScore

Conciseness

The body is technical and assumes Claude's competence (no padded concept explanations), but key rules are restated several times (e.g. 'MUST NOT BE PLACED IN panels/' repeated across Principles, Step 1, and Step 3) and the two concrete examples substantially duplicate the workflow steps and code, so it could be tightened.

2 / 3

Actionability

Provides fully executable TypeScript with exact import paths, BUILD.gn update steps, and concrete commands (autoninja -C out/Default, npm run lint), making the guidance copy-paste ready.

3 / 3

Workflow Clarity

A clear 6-step sequence with an explicit Create-vs-Update decision strategy and a Step 6 validation checkpoint (build, lint, tests) covering the destructive file moves/deletions in Steps 3 and 5.

3 / 3

Progressive Disclosure

No bundle files exist; the single-file content is well organized into Principles, Workflow, Examples, and Interface Reference with clear sections and no deeply nested references, meeting the simple/well-organized-skills allowance for a 3.

Description

67%

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 specific, well-scoped description for a narrow DevTools migration task, strong on specificity and distinctiveness. It is held back by the absence of an explicit 'Use when' trigger clause and by trigger terms limited to technical jargon rather than natural user phrasing.

Suggestions

Add an explicit 'Use when...' clause stating when to invoke this skill, e.g. 'Use when migrating or refactoring DevTools SettingRegistration blocks to the new descriptor split.'

Include a few natural-language trigger terms users might actually say (e.g. 'DevTools setting', 'setting registration', 'migrate setting') alongside the technical identifiers.

DimensionReasoningScore

Specificity

Names multiple concrete actions — splitting a SettingRegistration into a SettingDescriptor and a SettingUIDescriptor — with explicit placement targets (core/, models/, ui/settings/, higher-level -meta.ts), exceeding the 'names domain and some actions' level.

3 / 3

Completeness

Clearly answers 'what' (split registration into two descriptors with placement rules) but lacks any 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 2 per the judging guidelines.

2 / 3

Trigger Term Quality

Uses real domain keywords (SettingRegistration, SettingDescriptor, SettingUIDescriptor, -meta.ts) but only technical identifiers with no natural-language variations a user might casually say, matching 'some relevant keywords but missing common variations'.

2 / 3

Distinctiveness Conflict Risk

Targets a very specific DevTools setting-migration niche with named file layers and distinct identifiers, making it unlikely to trigger for the wrong skill.
