Inner loop validation

Validation in the inner loop, not the CI queue

AI development disrupted the balance between local iteration and remote validation. The problem: Agents commit fast; and CI feedback arrives after they’ve moved on.

The result: flooded pipelines, wasted tokens, and a growing gap between activity and delivery.

Chunk sidecars restore the balance. Lightweight checks run in the inner loop, where agents are actively working, so feedback arrives while the change is still in motion.

AI powered

AI infra for agentic development

AI generates complex code fast. Validation needs to keep pace. Chunk works across the inner and outer loops — catching failures before the push and keeping CI clean for everything that follows.

01

Inner loop validation

Chunk sidecars run alongside agents before any commit or push. Auto-detects your stack, fires validation hooks when the agent pauses, and returns 30x faster than your CI pipeline.

02

Outer loop automation

Chunk Tasks monitors, troubleshoots, and optimizes your CI pipelines autonomously. Resolves failures, reduces flaky tests, and keeps delivery moving without slowing your agents down.

03

Compounding efficiency

Validation that catches issues early means fewer retries, less rework, and less unnecessary context fed back to the agent. 5x fewer tokens spent. 30x more compute efficient than a full pipeline run.
