docs: add adversarial code review guide - #292
Conversation
A reproduce-by-execution method for reviewing high-risk PRs: isolate in a worktree and baseline, fan out independent skeptic sub-agents scoped one per risk surface, verify headline findings by execution, then rank and credit what's correct. Includes the reusable sub-agent prompt template.
📝 WalkthroughWalkthroughAdds a documented adversarial code review workflow and a matching command. The workflow covers isolated execution, baseline capture, independent sub-agent analysis, reproducible validation, finding verification, severity ranking, and optional review posting. The ignore rules keep the command tracked. ChangesAdversarial Review Workflow
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to The new review workflow can execute untrusted pull-request code with the reviewer’s host access, and it can misreview pull requests that use another base branch or the documented posting syntax. These are concrete security and correctness issues, so the PR is not ready to merge until they are addressed. Sequence Diagram(s)sequenceDiagram

Add a language identifier to the fenced prompt block.
The unlabeled fence triggers markdownlint MD040. Use text (or another suitable language) to keep documentation lint-clean.

Parse --post independently of the repository argument.
The hint permits /adversarial-review <PR#> --post. Line 14 treats every second argument as <REPO>. This invocation therefore passes --post as the repository and fails before the review. Parse flags independently and use only a remaining positional argument as the repository override.

Use the PR’s actual base commit.
The command fetches only headRefOid, then hard-codes upstream/main and main for the baseline and diff. A PR targeting another branch can compare against the wrong commit, which can misattribute existing defects or miss PR changes. Fetch baseRefOid and use baseRefOid...headRefOid.

🌐 Web query:
GitHub REST API pull request reviews pull request review comments pagination pull_request_review_id
💡 Result:
The GitHub REST API provides specific endpoints to list pull request review comments, including those scoped to a specific pull request review. All such endpoints support pagination via query parameters [1][2]. To list comments for a specific pull request review, use the following endpoint: GET /repos/{owner}/{repo}/pulls/{pull_number}/reviews/{review_id}/comments [1][3] Parameters for pagination: 1. per_page: The number of results per page (maximum 100). The default is 30 [1][3]. 2. page: The page number of the results to fetch. The default is 1 [1][3]. You can identify the specific review using the {review_id} path parameter [1][4]. General pagination behavior in the GitHub REST API relies on these parameters, and additional pages can be navigated using the link header provided in the API response [5][6]. If you are using Octokit.js, the octokit.paginate method can be used to automatically handle the fetching of all paginated results [5][6].

Fetch prior inline comments and paginate re-review data.
The re-review path calls only pulls/$1/reviews, while the required status table covers individual findings. Fetch pulls/$1/comments as well, paginate both endpoints, and correlate each comment through pull_request_review_id before assigning its status.

Do not execute PR-controlled code on the reviewer’s host.
Step 3 installs dependencies and runs repository-controlled commands after creating only a Git worktree. A worktree isolates files, not processes, credentials, host mounts, or network access. An untrusted PR can execute code with the reviewer’s permissions.
Run PR validation in a disposable sandbox with no host credentials, no writable host mounts, and restricted network access. Keep GitHub metadata operations and review posting outside the sandbox.

What
Adds
docs/adversarial-review.md— a documented method for reviewing high-risk PRs where every finding carries a reproduction or it doesn't ship.Why
We've been running this flow ad hoc on recent PRs (span-extraction, consistency guidelines, the memory-hooks seam) and it's caught real correctness bugs that green CI missed — fail-open compliance seams, silent signal inversions, crashes on realistic malformed inputs. This writes the method down so it's repeatable.
