From 5fa674b91ca65eef984f892c546cffa034ea3af6 Mon Sep 17 00:00:00 2001 From: "alexzhang2014@live.com" Date: Wed, 18 Mar 2026 02:35:47 +0800 Subject: [PATCH] feat(worker): add verify stage and harness closed-loop pipeline MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a new "verify" agent role for build/lint/type-check validation, with automatic failure redirect context passing (verify/test → code) so the coding agent can self-correct. Includes composite evaluator scoring from LLM confidence + external signals, project-level verify_commands config, tech_stack auto-detection, and a built-in "harness_pipeline" template (Code→Verify→Test with up to 3 retry loops).
