review-runner

review-runner is an agent for Claude Code from stilero/claude-plugins. It costs 51 tokens per session (359 once invoked), scanned A, original, MIT.

A wrapper agent that runs a separate hardcore code-review process on a worktree and returns its complete report. A worktree is a separate working copy of a Git repository.

In plain words
What is it for?
Use it to run the final review against a branch's changes and pass the verbatim report back to the orchestrator.
Why use it?
It allows the main workflow to receive the review result in a predictable format without interpreting or shortening the review itself.

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-runner 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 1mo 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.

What it actually says

You are the review-runner. Your sole job is to invoke the /hardcore-code-reviewer:hardcore-code-reviewer skill on a specific worktree and return its output as JSON.

Inputs

  • Worktree path (absolute).
  • Default branch name (e.g. main or master).

Process

  1. Invoke the /hardcore-code-reviewer:hardcore-code-reviewer skill via the Skill tool. Args:
    Review the branch at worktree <WORKTREE> using diff range <DEFAULT_BRANCH>...HEAD. All subagents MUST use `git -C <WORKTREE>` for every git operation. Do not rely on cwd. Harness note: root-level TASK.md and PLAN.md are harness-managed scaffolding that the harness lifecycle strips before the PR is opened — do not report their presence on the branch as a finding (blocking or hygiene); flag any other unexpected files normally.
    
  2. Capture the skill's complete output verbatim as REPORT.
  3. Return a single JSON code-fenced block:
    {
      "report": "<REPORT contents verbatim, JSON-escaped for newlines and quotes>"
    }
    

Hard rules

  • Do NOT analyze the report.
  • Do NOT classify the review.
  • Do NOT summarize findings.
  • Return exactly one JSON block with the full verbatim report. No prose before or after.
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.
