swe-loop

name	swe-loop
description	Use when the user has a coding prompt — a feature, bug fix, or refactor — and wants it implemented end to end by a self-checking software loop, not a single pass. It refines the prompt into an executable plan (running the plan-loop internally), then executes the plan task by task: an Engineer subagent implements each PR-sized task editing only source, a separate QA subagent authors the tests that prove the task's acceptance criteria (or grades quality only when tests already cover them), runs the task's tests plus the full accumulated regression suite, and grades the code against a strict conciseness/readability/style-match rubric; the Engineer and QA loop on each task until the tests pass and the quality gate holds, then it commits and opens a pull request for the task — stacked PRs (one per task, each based on the prior) by default, or one combined PR — and moves to the next task. Author and critic have disjoint write scopes (Engineer owns source, QA owns tests) so neither can game the gate. Not for producing a plan without building it (that is plan-loop), and not for tuning a metric on an existing artifact under a fixed correctness bound (that is optimize-loop).
compatibility	Requires Python 3.9+ and a runnable test command in the target repo.

SWE Loop

The execute stage of the prompt → plan → execute → debug pipeline: it turns a coding prompt into working, tested, well-organised code. It runs the plan-loop to get an executable tasks.json, then walks the tasks in dependency order. Each task is driven by two isolated subagents — an that writes the code and a that owns the tests and the quality bar — looping until the gate holds. The feedback signal is two-part, like the repo's other evaluator loops: an (the task's tests pass, the full regression suite stays green, and reports no threshold violation) and a (QA's score against — simplicity, readability, comment hygiene, organisation, style-match). One task is kept per outer step; one change is proposed per inner round, so every delta is attributable.
