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

Compiler Review

Review Rust compiler port code for correctness and convention compliance.

Arguments:

• $ARGUMENTS: Optional commit ref or range (e.g., HEAD~3..HEAD, abc123). If omitted, reviews uncommitted/staged changes.

Instructions

1. Get the diff based on arguments:

• No arguments: git diff HEAD -- compiler/crates/ (uncommitted changes). If empty, also check git diff --cached -- compiler/crates/ (staged changes).
• Commit ref (e.g., abc123): git diff abc123~1..abc123 -- compiler/crates/
• Commit range (e.g., HEAD~3..HEAD): git diff HEAD~3..HEAD -- compiler/crates/

1. If no Rust changes found, report "No Rust changes to review." and stop.

1. Identify changed Rust files from the diff using git diff --name-only with the same ref arguments.

1. Launch the compiler-review agent via the Agent tool, passing it the full diff content. The agent will:

• Read the architecture guide
• Find and read the corresponding TypeScript files
• Review for port fidelity, convention compliance, and error handling
• Return a numbered issue list

1. Report the agent's findings to the user.
