Review code, diffs, branches, commits, and pull requests for correctness, tests, simplicity, performance, and usability.
Debug cross-platform process, shell, sandbox, pipe, handle, startup, and shutdown behavior. Use for hangs, output loss, focus changes, lifecycle races, or platform-specific runtime failures.
Write deterministic tests that fail for real product defects. Use when adding tests, fixing flakes, or reviewing test coverage and reliability.
Review and merge open Dependabot pull requests across an organization or user. Use for dependency update triage, supply-chain checks on bumps, or bulk dependency merges.
Profile and optimize Go CPU, allocations, GC, concurrency, and I/O with benchmarks and pprof.
Profile and optimize Python CPU, memory, I/O, concurrency, and numerical performance.
Profile and optimize Rust CPU, memory, I/O, async, and build performance with representative benchmarks.
Diagnose and optimize TypeScript checker, build, V8, Node, and browser performance.
