devx-ux

Activate when designing or modifying CLI command surfaces, command help text, install/init/run flows, error wording, or first-run experience in the APM CLI -- even when the user does not say "UX" explicitly.

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.

The body is concise, well-structured, and provides concrete guardrail directives appropriate for an instruction-only skill. Its weakness is the absence of any validation checkpoint or worked examples for the error-wording rules it enforces.

Suggestions

Add a brief validation checkpoint to the rules (e.g., 'Before finalizing an error message, confirm it states the failure, the cause, and one next action').

Include one short before/after error-wording example to make the 'failure, cause, next action' rule copy-paste actionable.

DimensionReasoningScore

Conciseness

Lean ~25-line body with no padding and no explanation of concepts Claude already knows; every line earns its place and assumes Claude's competence.

5 / 5

Actionability

Concrete, checkable directives ('compare against npm/pip/cargo/gh', 'every error names failure, cause, one next action') rather than vague direction, but lacks before/after examples of good error wording that would make it copy-paste ready.

4 / 5

Workflow Clarity

Well-organized as a trigger list plus rules, but there is no sequenced workflow and no validation checkpoint (e.g., verify each error satisfies the failure/cause/next-action rule) for changes it governs.

3 / 5

Progressive Disclosure

Under 50 lines with no need for external references beyond a single clearly-signaled one-level-deep persona link, and well-organized into 'When to activate' and 'Key rules' sections.

Description

78%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.

The description is tightly scoped to APM CLI UX surfaces with strong, explicit trigger guidance and a distinctive 'activates even without the word UX' clause. Its main weakness is that the skill's actual action is implied rather than explicitly stated.

Suggestions

Add an explicit 'what' verb phrase stating the action the skill performs (e.g., 'Reviews and rewrites CLI UX surfaces...') before the 'Activate when...' trigger clause.

Include a couple of natural synonyms (e.g., 'command-line', 'CLI flags', 'usage text') to broaden trigger coverage.

DimensionReasoningScore

Specificity

Lists several specific CLI surfaces (command help text, install/init/run flows, error wording, first-run experience) rather than vague language, though it enumerates trigger surfaces more than concrete performed actions.

4 / 5

Completeness

Explicit 'Activate when...' trigger guidance is present and concrete, but the 'what does this do' is only implied via the verb 'Activate' rather than stated as an explicit action.

4 / 5

Trigger Term Quality

Strong natural terms ('CLI command surfaces', 'command help text', 'error wording', 'first-run experience', 'APM CLI') plus the distinctive 'even when the user does not say UX explicitly' clause, though a few synonyms are missing.

4 / 5

Distinctiveness Conflict Risk

Tightly scoped to the APM CLI with explicit boundary deferral to a separate CLI Logging UX skill, giving a clear niche with minimal conflict risk.
