Quality

Content

65%

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

The skill is concise and reasonably structured, but its workflow steps are direction rather than executable commands and lack a validation checkpoint, and it references a 'docs/perf-requirements.md' file that is not present in the bundle.

Suggestions

Replace vague step verbs with concrete commands (e.g. 'git log --oneline -20 -- <path>' and a specific grep/repo-map invocation) to make the workflow copy-paste executable.

Add a validation checkpoint (e.g. confirm each hypothesis cites a specific file/path or git change before emitting it) to reach the workflow_clarity anchor for 3.

Either add the referenced 'docs/perf-requirements.md' to the bundle or remove the dangling 'canonical contract' reference so progressive disclosure is clean.

DimensionReasoningScore

Conciseness

The body is lean with no concept explanations Claude already knows; every line (Required Steps, Output Format, Constraints) earns its place, matching the lean-and-efficient anchor.

3 / 3

Actionability

It gives a concrete YAML output schema and a MUST-check git constraint, but the workflow steps use vague direction ('repo-map or grep', 'Produce up to 5 hypotheses') rather than executable commands, landing at level 2 rather than 3.

2 / 3

Workflow Clarity

Three steps are clearly sequenced with a MUST-check ordering constraint, but there is no validation checkpoint verifying the hypotheses against evidence before output, so it stays at level 2 rather than 3.

2 / 3

Progressive Disclosure

Sections are well organized and the skill is short and single-purpose, but the body points to 'docs/perf-requirements.md' as the canonical contract and that file does not exist in the bundle, a dangling reference that prevents a top score.

Description

60%

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 complete and distinct with an explicit 'Use when' trigger, but it leans on skill jargon ('performance hypotheses') rather than the natural phrasing users would actually say. Adding common trigger terms like 'slow', 'perf', or 'optimize' would lift the weakest dimension.

Suggestions

Add natural user-facing trigger terms (e.g. 'slow', 'performance', 'perf', 'optimize', 'laggy') so users' real phrasing matches the description.

Expand the capability list with a second concrete action (e.g. 'Review recent git history, locate code paths, and rank hypotheses by confidence') to reach the specificity anchor for 3.

Keep the explicit 'Use when ...' clause but tie it to scenario cues users state (e.g. 'Use when a feature is slow or regressed and you need hypotheses about the cause').

DimensionReasoningScore

Specificity

Names the domain plus two concrete actions ('git history' and 'code evidence'), but stops short of listing the multiple specific operations the best anchor requires, so it sits at level 2 rather than 3.

2 / 3

Completeness

It states both what it does ('generating performance hypotheses') and an explicit 'Use when' trigger, satisfying the both-what-and-when anchor; not lower because the trigger is explicit, not merely implied.

3 / 3

Trigger Term Quality

'performance hypotheses' is skill-internal jargon; it lacks the natural terms a user would actually say (e.g. 'slow', 'perf', 'optimize', 'lag'), matching the no-natural-keywords anchor and ruling out level 2.

1 / 3

Distinctiveness Conflict Risk

The niche — perf hypotheses backed by git/code evidence — is narrow and unlikely to collide with other skills, fitting the clear-niche anchor; not lower because the trigger terms are specific enough to avoid overlap.
