Bun CPU Profile
Use this skill for TypeScript package scripts. The production CLI is Rust-first,
so native command performance work should use the ccusage-rust-profile skill
instead.
Workflow
Read references/profile-workflow.md before profiling. It contains the Bun
profiler commands, ccusage branch-vs-main setup, hyperfine validation,
profile-reading checklist, Bun reference lookup, and lessons from past ccusage
performance work.
