Use when you have lint errors, formatting issues, or before committing code to ensure it passes CI.

react/react

Skill Claude CodeCodex

Use when you need to check feature flag states, compare channels, or debug why a feature behaves differently across release channels.

react/react

Skill Claude CodeCodex

Use when you need to run Flow type checking, or when seeing Flow type errors in React code.

react/react

Skill Claude CodeCodex

Use when you need to run tests for React core. Supports source, www, stable, and experimental channels.

Agent Claude Code

Analyzes how a specific topic affects a group of compiler passes. Used by the /plan-update skill to parallelize research across all compiler phases. Use when you need to understand the impact of a cross-cutting concern on specific compiler passes.

react/react

Agent Claude Code

Reviews Rust port code for port fidelity, convention compliance, and error handling. Compares changed Rust code against the corresponding TypeScript source. Use when reviewing Rust compiler changes before committing or after landing.

react/react

Agent Claude Code

Investigates React compiler errors to determine the root cause and identify potential mitigation(s). Use this agent when the user asks to 'investigate a bug', 'debug why this fixture errors', 'understand why the compiler is failing', 'find the root cause of a compiler issue', or when they provide a snippet of code and…

Agent Claude Code

Ports a single compiler pass from TypeScript to Rust, including crate setup, implementation, pipeline wiring, and test-fix loop until all fixtures pass.

react/react

Skill Claude CodeCodex

Use when you want to verify compiler changes and commit with the correct convention. Runs tests, lint, and format, then commits with the [compiler] or [rust-compiler] prefix.

react/react

Skill Claude CodeCodex

Orchestrate the Rust compiler port end-to-end. Discovers the current frontier, fixes failing passes, ports new passes, reviews, and commits in a loop.

react/react

Skill Claude CodeCodex

Port a compiler pass from TypeScript to Rust. Gathers context, plans the port, implements in a subagent with test-fix loop, then reviews.

react/react

Skill Claude CodeCodex

Review Rust port code for port fidelity, convention compliance, and error handling. Compares against the original TypeScript source.

react/react

Skill Claude CodeCodex

Use when you need to run all compiler checks (tests, lint, format) before committing. Detects whether TS or Rust code changed and runs the appropriate checks.

react/react

Skill Claude CodeCodex

Use when you need to update a plan document with deep research across all compiler passes. Launches parallel subagents to analyze how a topic affects every compiler phase, then consolidates findings into the plan doc.

react/react

Skill Claude CodeCodex

Show the status of all Rust port plan documents and recent related commits. Use when you need to understand what's been done vs what remains.
