## Why update_milestone is rated Medium

This tool modifies an existing milestone's fields in a project management system. This is a Write operation because it creates or modifies data reversibly. While it changes state, the action is not destructive (no deletion), not executable code (no arbitrary execution), and not financial.

From the tool's own definition: "update_milestone - 'Update fields on an existing Huly milestone' performs modification of existing data (update action) with reversible effects."

## Use case

AI agents use update_milestone to create or update resources in Huly, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Huly environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Huly:
