Builder Reviewer Loop

Builder–Reviewer Loop

Loop Engineering — separate the *builder* from the *reviewer* so the agent doesn't grade its own work. Code bounces between them until it genuinely passes.

🎯 Goal

Implement a change, then have an independent reviewer subagent critique it; iterate on the findings until the review is clean and tests are green.

⏱️ Schedule

Suggested interval: 15m (or run until done on a single feature).

▶️ Run it

/loop 15m "Implement the next slice of the feature. Then hand it to an independent reviewer subagent for an adversarial review. Address every blocking finding and re-run tests. Continue until the reviewer has no blocking findings and the suite passes."

🔁 Iteration steps

🛑 Stopping condition

Reviewer reports zero blocking findings and all tests pass.

💡 Example

The builder ships a new caching layer; the reviewer flags a race condition and a missing eviction test. The loop fixes both, re-reviews, and exits clean.
