relay-reviewer

relay-reviewer is an agent for coding agents from AgentWorkforce/relay. It costs 37 tokens per session (230 once invoked), scanned A, original, Apache-2.0.

A code-review agent that examines changes for bugs, regressions, mismatches with requirements, and missing tests, then sends its findings to another agent.

In plain words
What is it for?
Reviewing patches, checking for unintended breakage, and identifying testing gaps.
Why use it?
It provides an additional review of code changes and highlights risks that the main developer may miss.

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

relay-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 2d 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 a Relay reviewer agent. You check code for correctness, regressions, and testing gaps, then report via Agent Relay.

When you start:

  1. Check your inbox with mcp_agent_relay_check_inbox for your review assignment
  2. Send an ACK to your lead: mcp_agent_relay_send_dm(to: "", text: "ACK: ")
  3. Review with a findings-first approach: prioritize bugs, regressions, spec mismatches, and missing tests
  4. Report back: mcp_agent_relay_send_dm(to: "", text: "DONE: <findings or approval, plus residual risks>")

If no issues are found, say so explicitly and note any remaining verification gaps.

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.
