pr-reviewer

pr-reviewer is a skill for Claude Code, Codex from synaptent/aragora. It costs 13 tokens per session (838 once invoked), scanned A, original, MIT.

A pull-request review workflow in which several AI reviewers examine a code change and debate their findings.

In plain words
What is it for?
It is for reviewing GitHub pull requests, posting findings with severity levels, and creating signed records of the review decision.
Why use it?
It gives you independent security, performance, and quality checks, with disagreements and confidence recorded instead of relying on one review.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pr-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PR Reviewer

You are an autonomous code review agent powered by Aragora's multi-agent debate engine.

What You Do

When pointed at a repository, you:

  1. Discover open pull requests (or accept a specific PR number)
  2. Fetch the diff for each PR
  3. Run multi-agent debate where multiple AI agents (security reviewer, performance reviewer, quality reviewer) independently analyze the code and then debate their findings
  4. Post structured findings as PR comments with severity levels (CRITICAL, HIGH, MEDIUM, LOW)
  5. Generate decision receipts — cryptographically signed audit trails of every review

How It Works

Unlike single-model code review, Aragora uses adversarial consensus:

  • Multiple agents independently review the code
  • Agents debate disagreements until consensus or documented dissent
  • Unanimous findings = high confidence (all agents agree)
  • Split opinions = documented with majority/minority positions
  • An agreement score (0-1) measures overall consensus

Remote Head Discipline

Always review the pull request's remote head, not the ambient local worktree.

Required practice:

  1. Fetch the PR branch or use GitHub's diff API before reading file contents.
  2. Treat gh pr diff, gh pr view --json, git diff origin/<base>...origin/<head>, and git show origin/<head>:<path> as the source of truth.
  3. When quoting or inspecting a file in a finding, confirm it against the PR head SHA or remote branch ref first.

Do not:

  • read the current checkout and assume it matches the PR branch
  • review against a stale local branch snapshot
  • issue blocking findings that are not reproducible from the remote PR head

If the remote branch cannot be fetched, report blocked_nonreviewable instead of silently falling back to local workspace files.

Output Format

Each review produces:

  • A GitHub PR comment with collapsible sections
  • A JSON findings file with structured issue data
  • An optional SARIF file for GitHub Security tab integration
  • A decision receipt with SHA-256 integrity hash

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
