/bench
Runs the benchmark harness and checks against the budget in CLAUDE.md section 13.
Workflow
bun run build — bench runs against the built artifact, not source.bun scripts/bench.ts --json — capture structured results.- Compare each scenario against its budget:
- cold start: ≤ 200 ms
- 10 files × 1 KLOC: ≤ 100 ms
- 100 files × 10 KLOC: ≤ 500 ms
- 1000 files × 100 KLOC: ≤ 3 s
- If all pass: append a row to
docs/performance.md with date | commit | scenario | ms | budget | margin, stage, and commit: perf(bench): record <shortsha> results.
- If any fail: dispatch
benchmark-tuner with the failing scenario and its measurement.
Return format
scenarios:
cold_start: <n>ms (budget 200ms, margin +<x>ms)
10_files: <n>ms (budget 100ms)
100_files: <n>ms (budget 500ms)
1000_files: <n>ms (budget 3000ms)
decision: PASS | FAIL
