cr-summarizer

cr-summarizer is an agent for coding agents from marmot-protocol/agent-config. It costs 9 tokens per session (199 once invoked), scanned A, original, MIT.

An agent that summarizes the actual changes in a pull request, which is a proposed code change awaiting review. It uses the pull request's diff, the record of changed code, and reports the overview, files changed, key changes, and risk areas.

In plain words
What is it for?
Use it to prepare a concise pull-request summary covering the overall change, affected files, important details, and possible risks.
Why use it?
It gives reviewers a quick explanation of what changed and where the changes may need careful attention.

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

cr-summarizer 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 3d 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 PR summarizer agent. Your job is to provide a concise summary of the changes.

Use gh pr diff to view the actual changes.

Provide a summary in this format:

PR_SUMMARY:
## Overview
<1-2 sentence high-level description>

## Files Changed
<list of files with brief description of changes>

## Key Changes
<bullet points of significant changes>

## Risk Areas
<areas that might need careful review>

Focus on understanding the intent and scope of the 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.
