Skill Reviewer

Reviews skills against a vendor-aware baseline normalized for local, smaller models.

Target: $ARGUMENTS (skill file or directory)

When to Use

Use when:

• auditing an existing skill before rework or publication
• reviewing a new skill draft
• baselining a whole skill directory before broader tuning
• checking whether a skill is too vendor-specific or too large-model-oriented
• deciding whether instructions should stay in prose or move into scripts/references

Review Priorities

Rank findings in this order:

1. Local-model fitness
2. Portability
3. Determinism
4. Context efficiency
5. Vendor alignment

What to Read

1. Read the target SKILL.md.
2. If the target is a directory, locate every SKILL.md under it and review each one independently before summarizing cross-cutting issues.
3. Always read:
   • references/review-rubric.md
   • references/local-first-normalization.md
4. Read references/vendor-guidance.md when:
   • the skill is clearly tuned to one vendor runtime
   • you need to judge whether vendor-specific advice is portable
   • you need to explain why a recommendation is down-ranked for local or smaller models
5. Read bundled references in the target skill only when needed to judge progressive disclosure, variant organization, or duplicated content.

Core Review Questions

Check the skill against these questions:

• Does the metadata clearly say when to use the skill, not just what it is?
• Is the main SKILL.md concise enough to justify its token cost?
• Does the skill use progressive disclosure instead of packing every detail into one file?
• Should any fragile or repeated procedure be moved into a script?
• Are outputs, tool results, or review expectations expressed as clear contracts?
• Does the skill assume a frontier model where a local or smaller model needs more structure?
• Are variants split by language, framework, or domain when needed?
• Does the skill provide fallback behavior when tools, files, or assumptions are missing?
• Does it include verification or success criteria when work is procedural?
• Does it contain vendor-specific advice that should be marked as optional or narrowed?

Review Rules

• Prefer portable guidance shared across vendors over product-specific tricks.
• Down-rank advice that assumes very large context windows or strong implicit inference.
• Flag vendor-specific recommendations when they do not transfer cleanly to local or smaller models.
• Treat missing progressive disclosure, missing contracts, and script-worthy prose as important issues.
• Prioritize behavioral and structural issues over generic writing polish.
• Do not praise trivialities.
• Provide diffs only for high-confidence changes that are easy to apply.

Findings to Emit

Use these labels when applicable:

• vendor_overfit
• frontier_model_assumption
• context_budget_risk
• missing_progressive_disclosure
• should_be_script
• missing_output_contract
• variant_bloat
• local_runtime_gap

Review Process

1. Identify the review target shape: single file, single skill directory, or multi-skill directory.
2. Read the core rubric and local-first normalization references.
3. Read the target skill and note its type: knowledge skill, workflow skill, search skill, reviewer skill, or tool-integration skill.
4. Evaluate metadata, scope, progressive disclosure, determinism, contracts, portability, and verification behavior.
5. Load vendor guidance only if a vendor-specific judgment is needed.
6. Record the highest-severity issues first, with locations.
7. Score the skill using the output format below.
8. Suggest structural edits or diffs only where they materially improve the baseline.

Output Format

## Skill Review: [skill-name]

### Summary
[1-2 sentences]

### Portable Strengths
- [High-value strength]

### Critical Issues
- [label] [Issue] - Location: [section/line]

### Local-Model Risks
- [Issue] - Impact: [why this hurts smaller/local models]

### Vendor-Overfit Risks
- [Issue] - Vendor: [name] - Why it may not transfer

### Baseline Recommendations
- [Actionable recommendation]

### Scores
- Portability: [1-5] - [brief reason]
- Context Efficiency: [1-5] - [brief reason]
- Determinism: [1-5] - [brief reason]
- Local-Model Fitness: [1-5] - [brief reason]
- Vendor Alignment: [1-5] - [brief reason]

### Overall Assessment
[Pass | Pass with Recommendations | Needs Revision]

### Suggested Diff
```diff
[Only include when high-confidence and useful]
```

Notes

• Prefer review comments that help establish a reusable baseline across many skills.
• If the target skill is already highly portable and local-model-friendly, say so explicitly.
• If the target is a directory, finish with a short cross-skill summary after the per-skill reviews.
