WHAT IT DOES

What run_doctor does on Todos

AI agents invoke run_doctor to trigger actions in Todos. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why run_doctor is rated High

This tool executes diagnostic and repair operations on a local system. While described as 'safe repairs' with 'dry-run review', the tool can still perform modifications to system state based on diagnostic results.

From the tool's definition Tool description states 'Run local doctor diagnostics and optionally apply safe repairs' — the 'apply' keyword indicates execution of repair operations whose effects depend on diagnostic findings and user arguments. 'Run' is a direct execution verb.

RECOMMENDED RULE

The rule that runs run_doctor safely

run_doctor Rate-limited

run_doctor stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
