Chunk sidecars
Launched this week
AI agents write code fast. Validation still happens after the push — by then the context is gone. Chunk sidecars run scoped microbuilds before commit, in a real CI mirror. Auto-detects your stack. ~27s average vs ~5 min billable compute for a full run. 3x–5x fewer tokens in retry loops. If something fails, the agent iterates before anything reaches shared CI.
Run chunk init. Works with Claude Code, Codex, Cursor, or custom agents. Free for all CircleCI users.
