What does debate-review do?

It runs a two-model debate before posting a review: a main reviewer finds issues, a debate reviewer tries to knock them down and may add its own, and the main reviewer makes the final call. The result is posted as a single non-approval review with inline comments to a PR or MR from the user's own account.

What commands does debate-review accept?

It accepts `node " /scripts/review-pr.mjs" --local [--base ]` for local diffs without a PR/MR URL, or `node " /scripts/review-pr.mjs" [--dry-run]` for existing PRs/MRs on GitHub, GitLab, or Azure DevOps.

What implementers should I pair for the debate?

The two reviewers should be different implementers since the debate only works when the second model doesn't share the first one's blind spots; main `claude` or `grok` paired with debate `codex` at high effort is named as a good pairing.

Does debate-review approve or request changes?

No, it never approves and never requests changes—it posts only as a non-approval review or comment.

How long does a debate-review run take?

A run takes minutes since it chains two or three implementer sessions back to back, so it should run in the background rather than being polled tightly.

Why it matters

Get thorough pre-merge code reviews by orchestrating two AI models that debate each finding before posting inline comments to your GitHub PR, GitLab MR, or Azure DevOps pull request-catching blind spots a single reviewer would miss.

Outcomes

What it gets done

Orchestrate a main reviewer model to identify issues in the diff

Run a debate reviewer model to challenge findings and surface new concerns

Synthesize the final review with inline comments posted to the PR

Cache all debate artifacts and timings for audit trails

Overview

Debate Review

Runs a two-model adversarial review on a PR, MR, or local diff: a main reviewer finds issues, a second implementer tries to refute or downgrade each and sweeps for gaps, and only findings that survive the debate are posted as inline comments or a summary. Use for any GitHub PR, GitLab MR, or Azure DevOps PR that needs a pre-merge review, or a local diff before a PR exists; requires two distinct delegate-skills implementer lanes with read-only relay support.

What it does

Runs a structured, adversarial two-model review before anything is posted to a PR, MR, or the terminal. A main-reviewer implementer finds issues and returns them as a debate-review.findings.v1 JSON document (file, line range on the new side of the diff, blocking/non-blocking severity, an axis of correctness/security/spec/standards/tests/docs, a claim, evidence, a recommendation, and a 0-1 confidence score - anything under the default 0.5 confidence floor is dropped before debate). A separate debate-reviewer implementer then tries to knock each finding down, returning a debate-review.debate.v1 document that gives every F* id exactly one verdict (confirm/refute/downgrade - a missing id counts as confirm with "no objection", and a bare refute with no evidence is recorded but weighted down to downgrade) plus its own gap-sweep new_findings (blocking only, with a named trigger). The main reviewer then makes a rebuttal pass and returns a debate-review.final.v1 document marking each finding agreed (posted), contested (posted with a tag, or dropped via --contested drop), or withdrawn (never posted, kept only in the run log) - a debate-reviewer finding the main reviewer rejects with evidence is always withdrawn, never contested, so a rejected second-model claim is never shown to the PR author. Exactly one non-approval review lands: a GitHub COMMENT review, or on GitLab/Azure DevOps a set of inline comment threads plus a summary thread - it never approves and never requests changes, and it posts from the user's own gh/glab/az account rather than a bot account. Each posted item carries a debate-review marker comment; on GitHub and GitLab the companion babysit-pr skill finds these threads by that marker (there is no bot author to match on) and drives verify/fix/reply/resolve rounds, though it cannot yet harvest Azure DevOps threads, so Azure findings are relayed to the user directly.

When to use - and when NOT to

Use it for any GitHub PR or GitLab MR that needs a thorough pre-merge review, for an Azure DevOps PR, or for a local working-tree review before a PR exists (--local, which never talks to a forge). The orchestrator's job is to run one command and relay the result - not to review the diff itself, and not to touch the PR directly. It requires two different delegate-skills implementer lanes (review-main and review-debate, added via delegate-setup) whose relays support --read-only, and the script refuses to run if either lane is missing; pick genuinely different implementers for the pair (main claude or grok, debate codex at high effort is suggested) so the debate reviewer doesn't share the main reviewer's blind spots, and don't reuse a lane dedicated to other work such as a plan-debate lane. Re-running on a head sha that already has a debate-review exits with code 3 unless --force is passed.

Inputs and outputs

Invocation:

node "<skill-dir>/scripts/review-pr.mjs" --local [--base <ref>]
node "<skill-dir>/scripts/review-pr.mjs" <pr-url | number> [--dry-run]

<pr-url> accepts a GitHub /pull/N, GitLab /-/merge_requests/N, or Azure DevOps /_git/<repo>/pullrequest/N URL (or the legacy *.visualstudio.com form); a bare number resolves against the cwd's origin. --dry-run prints the review instead of posting it (and does not combine with --local). A run takes minutes since it chains two or three implementer sessions, so it should run in the background rather than being polled tightly. Output is the posted review itself plus a run log at ~/.cache/debate-review/<owner>__<repo>/<N>/<head>/run.json (all three JSON documents, timings, and what was posted, alongside each implementer's brief and relay result) - or under ~/.cache/debate-review/local/<repo>/<branch>/<head>/ for a --local run.

Integrations

Requires Node 18+, Git 2.31+ for Azure DevOps, and an authenticated gh (GitHub), glab (GitLab), or az (Azure DevOps, via az login and the REST API through az rest - no CLI extension needed) - plus delegate-skills installed for the main and debate implementer lanes it depends on. Severity renders on the PR as GitHub/GitLab-native colored alert blockquotes ([!CAUTION] for a security-axis blocker, [!WARNING] for any other blocker, [!NOTE] for non-blocking); Azure DevOps shows the same blockquotes as plain quotes, which still read.

Who it's for

Teams and coding agents that want a pre-merge or pre-PR review with an adversarial second pass built in, so a lone reviewer's blind spot doesn't become the only signal before merge - across GitHub, GitLab, Azure DevOps, or a purely local diff.
