What problem does it solve? Rust development in the warp codebase often stalls on compilation errors, clippy warnings, formatting violations, WASM-specific build failures, and failing tests, and developers need a systematic way to resolve them before opening a pull request. ## Core Features & Use Cases - Presubmit Orchestration: Run the full presubmit suite (formatting, linting, tests) with a single script, or execute individual checks like cargo fmt, clippy, and nextest when debugging specific issues. - Error Pattern Catalog: Provides concrete fixes for common error types including unused imports, type mismatches, struct field changes, function signature changes, and enum variant updates. - WASM-Specific Guidance: Explains how to gate filesystem-dependent code and tests behind the local_fs feature flag to resolve wasm32-unknown-unknown target errors. - Use Case: A developer hits a clippy failure and a broken test after refactoring a struct. They follow the skill to fix the struct initialization sites, run targeted nextest filters, and verify everything with the presubmit script before opening their PR. ## Quick Start Ask the assistant to fix the current cargo build or clippy errors in the warp workspace and verify the fix by running the presubmit checks.
