## Why summarize_pr is rated Low

Summarizing a PR involves reading code changes (via git diff) and generating descriptive text. This is a read/query operation with no side effects on data, repositories, or external systems. The blast radius of misuse is minimal — at worst, a misleading summary is generated.

From the tool's own definition: "'Summarize the changes in this branch for a pull request' — the tool reads git diff data and produces a textual summary; no write, execute, or destructive operations indicated."

## Use case

AI agents call summarize_pr to retrieve information from MCP Server PR Pilot without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
