From 15181c1f6bfc2ee38099a03f23e5a1b065e8ddc9 Mon Sep 17 00:00:00 2001 From: Jarek Potiuk Date: Thu, 24 Sep 2026 14:30:05 +0200 Subject: [PATCH 1/3] feat(pr-management): with-reviewers: runs model CLIs as adversarial reviewers pr-management-code-review gains a tool path next to the slash path: `with-reviewers:codex,copilot` (or a configured adversarial-review.md whose mode is not off) has the agent run the adversarial-review tool over the PR at Step 5 and fold the findings in, attributed per reviewer. `with-reviewer:` and Review preferences keep the propose-and-type flow. A private repository's PR asks before the first tool run. Eval suite pr-management-code-review/step-2-reviewer-resolution (6 cases). The implementation plan is folded into the design's As built section and deleted, per docs/designs/README.md.

- - - - -# Adversarial Review Implementation Plan - -> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. - -**Goal:** Ship `tools/adversarial-review`, a stdlib-only CLI that runs other models' CLIs (Codex, Copilot, Gemini, Claude) read-only over a change and prints merged findings as JSON. Publish it as the `magpie-adversarial-review` substrate plugin (PR 1). Then wire it into `setup` (PR 2), into every PR-creating skill (PR 3), and into `pr-management-code-review` (PR 4). - -**Architecture:** The package has one small module per responsibility: - -- `backends`: one adapter per CLI, holding its argv, the harness self-markers and its output envelope. -- `detect`: finds which CLIs are installed and which harness is running. -- `prompt`: the input builder. It is also the privacy boundary: only the diff, the file list and the public PR text get in. -- `findings` and `merge`: parse each reply and de-duplicate across reviewers. -- `runner`: runs the reviewers in parallel, each in its own process group with a timeout. -- `config`: parses `adversarial-review.md`. -- `cli`: argparse front end. - -Every reviewer gets the same prompt: on stdin, or through a brief file for Copilot. Every reviewer's result is reported, including unavailable, timed-out and skipped ones. The tool exits 0 whenever the run completes, because the review is advisory. - -**Tech Stack:** Python ≥ 3.11, standard library only (`argparse`, `subprocess`, `concurrent.futures`, `difflib`, `json`, `re`, `tempfile`). Tests use pytest from the workspace root `dev` group. Packaging is hatchling, and it is a uv workspace member. - -**Spec:** [`docs/designs/2026-09-23-adversarial-review.md`](2026-09-23-adversarial-review.md) - -## Global Constraints - -- Runtime is stdlib-only: `dependencies = []`, no `[dependency-groups]` and no `[tool.uv.sources]` in `tools/adversarial-review/pyproject.toml`. The package ships as a plugin and must resolve standalone, the same exception `tools/vetted-ops` has. -- `requires-python = ">=3.11"`. Ruff line length is 110. Mypy runs strict on `src` (`disallow_untyped_defs = true`). -- Reviewer input is limited to the diff, the changed-file list, and the PR title and body *as they will be posted*. No function or CLI option accepts any other context. -- Every backend argv stays read-only and must never contain `--allow-all-tools`, `--allow-all-paths`, `yolo`, `auto_edit`, `danger-full-access`, `workspace-write`, `--full-auto`, `--dangerously-bypass-approvals-and-sandbox`, `--dangerously-skip-permissions` or `bypassPermissions`. -- The review is advisory: `run` exits `0` whenever it completes, whatever the reviewers' statuses. It exits `2` only for usage, config or input errors. -- The running harness's own model is skipped by default. `--self ` overrides the detection. -- The documented invocation is single-line, for the sandbox exclusion: `uvx --from /tools/adversarial-review adversarial-review …`. -- Every new `.py` file starts with the 16-line ASF license header copied verbatim from `tools/vetted-ops/src/vetted_ops/cli.py` lines 1–17 (the `#` block). Every new `.md` file starts with the two-line `` comment. -- Commits follow Conventional Commits and end with `Generated-by: Claude Opus 5`. Never add `Co-Authored-By:`. -- Work only in the `design/adversarial-review` worktree (or a branch off it per PR). Git commands in this worktree need the sandbox bypass because its `.git` points into `~/code/magpie`. Announce each one as `**!!! SANDBOX BYPASS: git in the magpie worktree (.git under ~/code/magpie) !!!**`. -- Test runner, once per session: `UV_CACHE_DIR=$TMPDIR/uvc uv sync --all-packages --group dev` at the worktree root, then `UV_CACHE_DIR=$TMPDIR/uvc uv run --directory tools/adversarial-review pytest -v`. This matches CI in `.github/workflows/tests.yml`. - -**Deviation from the spec (on purpose):** `detect` cannot tell whether a CLI is logged in without making a model call, which the spec rules out for `detect`. So `detect` reports installed and version only. A logged-out CLI is reported `unavailable` by `run` when its CLI exits with an auth error (Task 7). - -## Review Focus - -1. **A reviewer CLI leaves a grandchild process holding stdout past the timeout.** Node CLIs spawn helpers. The expected behaviour is that `run` still returns shortly after the timeout, with that reviewer marked `timeout`. Pinned by `test_timeout_kills_the_whole_process_group` (Task 7). -2. **Another harness's environment variables leak into the session.** This session carries `CODEX_COMPANION_*` while running inside Claude Code. The expected behaviour is that `self` stays `claude`. Pinned by `test_leaked_companion_vars_do_not_mark_codex` (Task 3). -3. **A very large diff**, past `ARG_MAX` or past model context. The expected behaviour is that the prompt still reaches every reviewer (stdin or a brief file, never argv), truncated with a visible marker and `"truncated": true` in the report. Pinned by `test_large_diff_is_truncated_with_marker` (Task 4) and by the backend snapshots, which keep the diff out of argv (Task 2). -4. **An empty diff** (the branch equals its base). The expected behaviour is that no model is called and the report says why. Pinned by `test_empty_diff_runs_no_reviewer` (Task 9). -5. **Running from a checkout of the private tracker itself**, where reviewers can read every file with their read-only tools. The expected behaviour is a plain warning in the report, not a refusal: the user rejected a gate. Pinned by `test_tracker_checkout_warns` (Task 4). - ---- - -## File Structure (PR 1) - -```text -tools/adversarial-review/ -├── pyproject.toml # stdlib-only, console script, no dev group -├── README.md # usage, output, backends, sandbox, privacy boundary -├── src/adversarial_review/ -│ ├── __init__.py # exports main -│ ├── __main__.py # python -m adversarial_review -│ ├── _util.py # first_line() -│ ├── backends.py # RunContext, Invocation, Backend, BACKENDS -│ ├── detect.py # running_harness, resolve_self, detect -│ ├── prompt.py # ReviewInput, make_input, render_prompt, diff sources, tracker_warning -│ ├── findings.py # Finding, FINDINGS_SCHEMA, extract_json, parse_findings -│ ├── merge.py # MergedFinding, merge -│ ├── runner.py # ReviewerResult, run_one, run_all -│ ├── config.py # ReviewConfig, parse, resolve -│ └── cli.py # detect / run subcommands -└── tests/ - ├── conftest.py # stub_bin, git_repo, clean harness env - ├── test_packaging.py - ├── test_cli.py - ├── test_backends.py - ├── test_detect.py - ├── test_prompt.py - ├── test_findings.py - ├── test_merge.py - ├── test_runner.py - └── test_config.py -plugins/magpie-adversarial-review/ # generated by check-family-plugins.py --fix -``` - -Modified: root `pyproject.toml` (workspace member), `uv.lock`, `tools/dev/README.md` (no-dev-group exception), `tools/dev/check-family-plugins.py` (substrate entry), `.claude-plugin/marketplace.json` (generated), `docs/designs/README.md` and the design's status line. - ---- - -## PR 1 — `tools/adversarial-review` and the substrate plugin - -### Task 1: Package scaffold, workspace registration, CLI skeleton - -**Files:** -- Create: `tools/adversarial-review/pyproject.toml` -- Create: `tools/adversarial-review/src/adversarial_review/__init__.py`, `__main__.py`, `cli.py` -- Create: `tools/adversarial-review/tests/conftest.py`, `tests/test_packaging.py`, `tests/test_cli.py` -- Modify: `pyproject.toml` (root) `[tool.uv.workspace] members`, `uv.lock`, `tools/dev/README.md:30-32` - -**Interfaces:** -- Produces: - - `adversarial_review.main(argv: Sequence[str] | None = None, env: Mapping[str, str] | None = None) -> int` - - `cli.build_parser() -> argparse.ArgumentParser` - - `cli.EXIT_OK = 0` and `cli.EXIT_USAGE = 2` - - conftest fixtures `stub_bin -> tuple[Path, Callable[[str, str], Path]]` and `git_repo -> Path`, plus the autouse fixture `_clean_harness_env` - -- [ ] **Step 1: Write the failing tests** - -`tools/adversarial-review/tests/conftest.py`: - -```python -from __future__ import annotations - -import subprocess -import sys -from collections.abc import Callable, Iterator -from pathlib import Path - -import pytest - -HARNESS_MARKERS = ("CLAUDECODE", "GEMINI_CLI", "CODEX_SANDBOX", "CODEX_THREAD_ID", "COPILOT_CLI") - - -@pytest.fixture(autouse=True) -def _clean_harness_env(monkeypatch: pytest.MonkeyPatch) -> Iterator[None]: - """Tests must not see the harness that happens to be running them.""" - for var in HARNESS_MARKERS: - monkeypatch.delenv(var, raising=False) - yield - - -@pytest.fixture -def stub_bin(tmp_path: Path) -> tuple[Path, Callable[[str, str], Path]]: - """A directory for fake CLIs;

The branch review then changed it as follows. The branch, not this plan, is the reference. - -- **Runner:** output goes to temporary files rather than pipes. The wait ends when the reviewer exits, so a finished reply is no longer lost to a helper holding stdout, and a helper that calls `setsid` cannot stretch the timeout. The process group is always killed afterwards. A SIGINT/SIGTERM handler kills every live group. -- **Auth detection:** it reads stderr only, against specific auth messages (it had matched `login`, `401` and `credential` anywhere). -- **Parsing:** - - The last JSON object by position wins, fenced or not. - - Findings are parsed one at a time, so a bad one is skipped and reported (`reason`, `raw`) instead of voiding the reply. - - Line ranges become their first line, unknown severities become `low`, and `file` and `evidence` may be empty. - - Paths are normalised against the repo (`./`, `a/`, `b/`, absolute). -- **Merge:** escalating to a more severe report carries its file and line along with its claim. -- **Backends:** `codex -c mcp_servers={}`, `claude --strict-mcp-config`, and `Task` added to Claude's denied tools. -- **CLI and defaults:** `--timeout-minutes` must be greater than 0. The default timeout is 8 minutes, under a harness's 10-minute shell-call cap. `prompt._run` maps any `OSError` to an input error. -- **Residual risks documented** in the README and the spec: `codex` read-only mode does not confine reads, and `copilot`/`gemini` keep their MCP servers. - ---- - -## PR 2 — `setup`: detection, configuration, per-harness commands, sandbox - -Task-level. Each task follows the same TDD loop as PR 1. - -### Task 2.1: `commands --harness ` in the tool -- **Files:** `tools/adversarial-review/src/adversarial_review/commands.py`, `cli.py`, `tests/test_commands.py`. -- **Produces:** `render(harness: str, plugin_root: str) -> tuple[str, str]`, returning (target path relative to the harness home or project, file content). The CLI is `commands --harness claude|codex|gemini|copilot --plugin-root ` and prints `{"path", "content"}` JSON. -- **Content per harness:** - - Codex: `~/.codex/prompts/magpie-adversarial-review.md`, telling the agent to run the one-line `uvx --from … adversarial-review run --target $ARGUMENTS` and show the report. - - Gemini: `.gemini/commands/magpie-adversarial-review.toml` with `description` and a `prompt` using `!{…}` shell injection of the same line. - - Copilot: no command file; `path` is empty and `content` is the one-line invocation to print. - - Claude: the plugin command file (Task 2.2). -- **Tests:** a snapshot per harness. An unknown harness exits 2. Every content includes `--self` detection, never a hard-coded reviewer list. - -### Task 2.2: Claude Code command shipped in the plugin -- **Files:** `plugins/magpie-adversarial-review/commands/adversarial-review.md` (generated from `commands.render("claude", …)` so it cannot drift), plus `tools/dev/check-family-plugins.py`, which must let this one substrate carry `commands/` (today substrates may not carry `skills`, and a `commands/` directory must not trip the orphan check). -- **Note for the user:** Claude Code namespaces plugin commands, so the invocation is `/magpie-adversarial-review:adversarial-review`, not the bare `/magpie-adversarial-review` the spec table shows. Update the spec table in this PR. -- **Tests:** a check-family-plugins test that the command file matches `render("claude")` byte for byte. - -### Task 2.3: Configuration template and `setup config` -- **Files:** `projects/_template/adversarial-review.md` (the spec's YAML block with comments) and the `setup` config flow under `plugins/magpie-setup/skills/setup/` (its config sub-doc). -- **Behaviour:** run `adversarial-review detect`, list the available non-`self` backends, ask which to enable (default: all of them), and write `.apache-magpie-local/adversarial-review.md`.
