Review code through BurntSushi's "honest machinery" lens — asking whether APIs, invariants, error contracts, performance boundaries, and defaults accurately represent reality. Use when reviewing library APIs, patches that change complexity or cost, dependency additions, or when the user asks "is this API honest?", "will this panic?", "is the cost visible?", "does this scale?", or "are the defaults right?". Works across languages; see REFERENCE.md for Rust-specific elaborations. Do NOT use for deletion/anti-bloat review (use code-review-russ-cox) or product-vs-library tradeoffs (use code-review-mitsuhiko).

# code-review-burntsushi

> "Is there a reasonable expectation that the code will behave as advertised?" — BurntSushi

A code review should ask: is this code *honest* about its invariants, failure modes, costs, and semantics? Not just: does it work?

## Quick start

Paste a diff or file and say "burntsushi review" or "honest review". Walk the ten general axes in [REFERENCE.md](REFERENCE.md), add the two Rust-specific axes if the code is Rust, then emit findings.

## Steps

1. **State the change** — what is this patch doing in one sentence? If unclear, ask first.
2. **Walk all ten general axes** from [REFERENCE.md](REFERENCE.md) in order. Flag every axis with a finding.
3. **If Rust:** also apply the two Rust-specific axes (encoding invariants, ownership/allocation).
4. **Emit findings** in the output format below.

## Output format

```
## Summary
<one paragraph: overall verdict and the single most important honesty gap>

## Must fix
- [Axis N | file:line] <finding — name the invariant, cost, or failure mode>.
  Suggestion: <one concrete alternative>.

## Consider
- [Axis N | file:line] <finding>.
  Tradeoff: <what's gained vs. lost>.

## Praise
- <what is genuinely honest — name it specifically>

## Open questions
- <anything needing author context before a final call>
```

## Tone rules

- Name the invariant, failure mode, or hidden cost precisely.
- Suggest one practical alternative per finding.
- Do not nitpick style, naming, or formatting unless it obscures correctness or cost.
- Do not complain about `unwrap`/assertions on static programmer invariants — only flag panics when the failure source is runtime/user/environment.

## Reference

- [REFERENCE.md](REFERENCE.md) — all axes with examples, model comments, and skill rules.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
