diagnose

Disciplined diagnosis loop for hard bugs and performance regressions. Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says "diagnose this" / "debug this", reports a bug, says something is broken/throwing/failing, or describes a performance regression.

Quality

Content

92%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 well-structured, highly actionable debugging discipline with strong workflow sequencing and validation gates. The only weakness is minor stylistic padding that slightly undercuts token efficiency.

Suggestions

Trim motivational slogans ("Be aggressive. Be creative. Refuse to give up.", "Build the right feedback loop, and the bug is 90% fixed.", "A 2-second deterministic loop is a debugging superpower.") to recover tokens without losing guidance.

The Phase 1 enumerated loop types could be tightened by collapsing closely related variants (e.g., items 8 and 9 both concern differential/bisection approaches) to reduce list length.

DimensionReasoningScore

Conciseness

Dense and assumes Claude's competence throughout, but a few slogan-like lines ("Be aggressive. Be creative. Refuse to give up.", "the bug is 90% fixed", "a debugging superpower") are emphasis rather than information and could be trimmed.

4 / 5

Actionability

Provides ten concrete loop-construction techniques plus specific mechanisms (git bisect run, performance.now(), [DEBUG-a4f2] tag prefix, grep cleanup) and a real referenced script — fully executable guidance for an instruction-oriented skill.

5 / 5

Workflow Clarity

Six clearly sequenced phases with explicit validation gates ("Do not proceed to Phase 2 until…"), checklists in Phases 2 and 6, and fail/pass feedback loops in the fix phase.

5 / 5

Progressive Disclosure

Well-organized with clear section headers; the single external reference (scripts/hitl-loop.template.sh) is one level deep, exists on disk, and is clearly signaled inline in context.

Description

100%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 tight, well-constructed description that explicitly states concrete capabilities and a rich set of natural trigger phrases, cleanly answering both what and when with minimal conflict risk.

DimensionReasoningScore

Specificity

Lists multiple concrete actions in an explicit chain — "Reproduce → minimise → hypothesise → instrument → fix → regression-test" — giving comprehensive coverage of the skill's capabilities.

5 / 5

Completeness

Explicitly answers both what (the disciplined diagnosis loop with its phase chain) and when (a concrete "Use when…" clause with multiple trigger phrases), in third person.

5 / 5

Trigger Term Quality

Includes natural phrases users actually say — "diagnose this", "debug this", "broken/throwing/failing", "performance regression" — covering synonyms and common variations.

5 / 5

Distinctiveness Conflict Risk

Carves a clear niche — "hard bugs and performance regressions" — with distinctive trigger phrases, giving minimal overlap risk with general coding skills.
