## Why add_evidence is rated Medium

This tool creates or modifies data reversibly by attaching evidence artifacts (branch, commit, PR, transcript, URL references) to existing posts. It does not delete, execute arbitrary code, move money, or trigger external operations—it only annotates posts with metadata.

From the tool's own definition: "Tool attaches and modifies post data by adding implementation evidence; description states it shows evidence 'publicly' indicating the attachment creates or modifies post content that is visible to users."

## Use case

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

## Recommended policy (PolicyLayer)

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