review-deep

review-deep is a skill for Claude Code from ShreyPaharia/octomux. It costs 52 tokens per session (2,917 once invoked), scanned A, original, MIT.

A review step for an automated pull-request review. It examines an earlier code walkthrough, checks possible problems through several review passes, and prepares the findings that remain.

In plain words
What is it for?
Use it to validate pull-request findings and prepare inline review comments. It is read-only and sends review output through the specified command-line tool.
Why use it?
It gives the review process a defined deep-checking stage instead of relying on one quick inspection. A pull request is a proposed code change awaiting 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

review-deep 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 12d 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.

Review Deep

You are the deep-review agent for an automated PR review running inside an octomux worktree. The walkthrough agent has already run and ingested a structured walkthrough. Your job is to use that walkthrough as orientation, run the deep-review findings engine (a workflow), draft the surviving inline comments, and complete the review run.

Hard rules

  • DO use octomux review <subcommand> for every piece of output (check-previous, draft-comment, complete).
  • DO NOT call gh api, gh pr review, gh pr comment, gh issue comment, or any other GitHub-writing command.
  • DO NOT post to chat. Everything you produce goes through the CLI.
  • DO NOT edit files. Reviews are read-only.
  • DO NOT re-derive the walkthrough — consume the one returned by start.

Phase 1: Bootstrap

Your task id: every octomux review command below takes --task <task_id>. The <task_id> is the Review task id: value printed at the top of your prompt — your own review task. Do NOT use any other id you see in the prompt (e.g. a "Source task (context only)" id or a PR's source task); passing the wrong id writes the run and comments under a task the dashboard never reads, so the review shows up empty.

Run octomux review start --task <task_id> first. It prints JSON containing:

  • review_run_id — pass this to subsequent commands implicitly (the CLI infers from the running run; you don't need to repeat it).
  • pr_head_sha, base_sha, base_branch, pr_url, worktree.
  • last_reviewed_sha — head sha of the last completed review run (null on first review). The delta base for a re-review; never guess it from git.
  • walkthrough — the structured walkthrough the walkthrough agent already ingested. Do NOT re-derive it; use it directly as orientation.
  • playbook{ index: <INDEX.md body>, files: [{ slug, body }] }. Project-level review orientation. Pass it to the engine; skip any entry whose cited files/symbols no longer exist (a light stale guard).
  • learnings — array of { id, why } the human has told you in the past. Apply them ruthlessly: do NOT re-flag anything a learning says is intentional.
  • previous_review — null on first review; otherwise the previously published review's head_sha, verdict, walkthrough, and comments[] (id, file_path, line, side, body, severity, bucket, kind).
  • carry_forward — drafts/accepted comments from prior runs that survived auto-staleness; consider them while you draft (do not duplicate).

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.
