From ccdc7265ebdf722923dab6e1a3dc01be2aa4243f Mon Sep 17 00:00:00 2001 From: mchwang Date: Fri, 23 Oct 2026 12:12:52 -0700 Subject: [PATCH 01/38] Add the review agent's prompt, answer schema and lane D command (#201 part 1) The review agent (design, 'Review rounds' step 1) answers one round as JSON: lane D's Claude review command now carries an answer schema, as planning's does, with planning's model budget. prompts/review.md and core/review-prompt.ts build the round's request with untrusted text in escaped data blocks, and validate the answer, splitting a problem that names several plan items into one per item. scripts/record-review.ts records real Claude output, which test/review-recorded.test.ts replays; a Docker test proves the command and schema reach the vendor. The runner does not run review rounds yet (part 2).

The recording repository commits the code before and after the plan, and plants an unrelated edit in a declared file. The recording script deletes its temporary file when a write fails.
