gitnexus-impact-analysis

Use when the user wants to know what will break if they change something, or needs safety analysis before editing code. Examples: "Is it safe to change X?", "What depends on this?", "What will break?"

Quality

Content

96%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.

An exemplary skill body: lean, concrete, and immediately executable, with a clear workflow, checklist, error-recovery path, and a worked example. The only structural note is that detailed tool output examples are all inline, which is acceptable at this size but worth splitting if the skill expands.

DimensionReasoningScore

Conciseness

The ~95-line body is lean with no explanations of concepts Claude already knows: terse sections ("## Workflow", "## Checklist"), compact risk tables, and a worked example that adds concrete grounding the abstract workflow lacks. Every token earns its place.

5 / 5

Actionability

Tool calls are fully concrete with parameters (impact({target, direction: "upstream", minConfidence: 0.8, maxDepth: 3})), sample outputs with real symbol names and confidence values, and an exact terminal recovery command (node .gitnexus/run.cjs analyze).

5 / 5

Workflow Clarity

The 4-step numbered workflow, checklist, and explicit error-recovery feedback loop ("If 'Index is stale' → run node .gitnexus/run.cjs analyze") sequence the process clearly with a reporting checkpoint. This is read-only analysis, so the destructive-operation validation cap does not apply.

5 / 5

Progressive Disclosure

The body is well-sectioned with no nested references and no buried content, appropriate for a standalone skill with no bundle files. Not 5 because the detailed tool-output examples in the Tools section are fully inlined with no external split, a minor organization gap if the skill grows.

Description

70%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 strong description with highly natural trigger phrases and an explicit 'Use when' clause. Its main weakness is that capabilities are expressed as user intents rather than concrete skill actions, leaving the 'what' slightly implicit.

Suggestions

Lead with a capability statement in third person (e.g., 'Performs impact analysis to map what breaks when code changes') before the 'Use when' clause.

Add synonyms users naturally say, such as 'impact', 'blast radius', or 'refactor', to broaden trigger coverage.

Name 1-2 concrete outputs of the analysis (e.g., 'identifies direct and indirect dependents') to sharpen the what.

DimensionReasoningScore

Specificity

The description names the domain ("safety analysis before editing code") and implies 1-2 actions ("know what will break if they change something"), but capabilities are phrased as user intent rather than distinct skill actions like 'maps blast radius' or 'finds dependents'.

3 / 5

Completeness

An explicit 'Use when...' clause with concrete trigger examples covers the 'when' thoroughly, and the 'what' is stated ("know what will break", "safety analysis"), but the what is woven into the when-clause rather than presented as a distinct capability statement. Not 3 because the when is fully explicit, satisfying the missing-trigger cap.

4 / 5

Trigger Term Quality

The quoted examples "Is it safe to change X?", "What depends on this?", and "What will break?" are natural phrases users would say. It falls short of 5 because synonyms like "impact", "blast radius", or "refactor" are absent.

4 / 5

Distinctiveness Conflict Risk

Pre-edit safety/impact analysis is a clear niche with distinct triggers, but "before editing code" slightly overlaps with general code-review or editing skills. Not 5 because the broad editing context leaves minor conflict risk.
