Review one mvsep-rs rewrite batch quality gate without writing production code. Use when the user asks for behavior parity review, error tracing review, async or ergonomics review, data structure or algorithm review, Rust style audit, frontend UX audit, or promotion readiness for a mvsep-rs migration batch.

Expand dependency sources and align canonical shared capabilities, Rust crate reuse, adapters, hand-written Burn gaps, fixtures, and bootstrap records for Vocal2Midi. Use before implementation when imports, native/FFI sources, dependency mismatch, shared model prerequisites, temporary dependency copies, Cargo coordination, or manifest re-cut decisions affect a unit.

Review one Vocal2Midi Rust migration unit quality gate without writing production code. Use for Python/Rust behavior parity, dependency/seam, error tracing, data/algorithm, Rust style, architecture, ergonomics, or promotion readiness.

Coordinate the Vocal2Midi Python-to-Rust rewrite. Use when the user asks to continue, plan, route, re-cut, shard, implement, audit, promote, choose serial or coordinated-parallel execution, or select the next migration unit; when shared Burn gaps, dependency source expansion, capability coverage, or workflow may change the manifest inventory.

Implement exactly one confirmed Vocal2Midi Rust migration unit as the writer role. Use when dependency discovery has accepted the boundary, canonical dependencies, and legacy public behavior seam, and the user asks to add fixtures, port behavior, or prepare one unit for review. Do not use for review-only or shared dependency coordination requests.

[DRAFT] 消费 crate reconnaissance 或用户手动生态证据，按 NOTES.md 中的偏好对齐 Python/Rust 或 legacy/Rust 依赖。覆盖 canonical shared dependencies、crate/backend/adapter/手写能力组合、manifest 重切、seam、验证和桥接；用于避免串行或并行 writer 创建冲突依赖副本。

[DRAFT] 跑通迁移 seam 的最小环境。根据项目选择 FFI、CLI、service、Tauri command、library 或 pipeline adapter，并证明参数、返回值、错误、日志和并发边界可用。

[DRAFT] 第 0 轮行为一致性门禁。对一个迁移单元或已收批的 review batch，独立证明旧实现与新实现在选定 public seam 后行为一致；不写生产代码，只运行/补充对比证据并输出报告。

[DRAFT] 第 1 轮 Rust 工程化审查。对一个迁移单元或已收批的 review batch 检查 Rust 模块结构、可见性、所有权、lint 和可维护性；默认审查不改生产代码，修复需单独实现并重跑 R0。

[DRAFT] 第 2 轮错误与追踪审查。对一个迁移单元或已收批的 review batch 检查结构化错误、上下文、日志、trace 传播和敏感信息保护；默认审查不改生产代码，修复后必须重跑行为门禁。

[DRAFT] 第 3 轮 IO、并发与运行时人体工学审查。对一个迁移单元或已收批的 review batch 检查阻塞 IO、async 边界、取消、重试、并发限制和运行时嵌套；默认审查不改生产代码。

[DRAFT] 第 4 轮算法复杂度审查。对一个迁移单元或已收批的 review batch，只在有复杂度分析、理论依据和 benchmark 证据时建议或实施算法改变；默认审查不改生产代码。

[DRAFT] 第 5 轮架构与数据结构审查。对一个迁移单元或已收批的 review batch 检查 ownership、API 边界、canonical storage、data structures 和 seam 深度；默认审查不改生产代码，架构修改需独立实现与复审。

[DRAFT] 第 6 轮产品、CLI、UX 与运维人体工学审查。对一个迁移单元或已收批的 review batch，从用户和维护者视角检查恢复、批处理、缓存、错误可读性、配置、可访问性和 workflow；只产出报告。

[DRAFT] 初始化 py2rs 重写偏好并建立迁移控制面：维护 manifest/shards、迁移粒度、强行为一致性验证、审核批次、默认串行执行、协调式并行、canonical shared dependencies、Cargo build 调度、状态机、回滚和审计。

Python-to-Rust 渐进式重写总 skill。用于规划、实施或审查系统级重写：读取项目事实与架构 seam，校准迁移粒度、审核频率、重写力度和依赖偏好，通过可选的独立 crate 侦察、能力对齐、manifest、回滚路径和质量门逐步替换旧实现。

Research Rust crate candidates and their feature/dependency paths before py2rs dependency alignment. Use when a migration unit may introduce or hand-write Rust behavior, when a named crate appears too high-level, when crate reuse is being rejected, or when py2rs needs registry evidence before allowing implementation.
