WHAT IT DOES

What delete_snapshot does on Why Did You Render

AI agents call delete_snapshot to permanently remove resources in Why Did You Render, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_snapshot is rated Critical

The tool removes stored snapshots without possibility of recovery. While snapshots are development artifacts rather than production data, deletion is permanent and cannot be undone. This makes it Destructive rather than Write. An AI agent could misuse this by deleting all snapshots, losing performance history and diagnostic data needed for debugging.

From the tool's definition Tool name 'delete_snapshot' combined with description 'Deletes a saved render snapshot by name' explicitly performs irreversible deletion of data.

RECOMMENDED RULE

The rule that runs delete_snapshot safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Why Did You Render, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_snapshot, this is the rule to start with:

delete_snapshot Hidden

delete_snapshot is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
