WHAT IT DOES

What generate_narration_audio does on CoWork OS

AI agents invoke generate_narration_audio to trigger actions in CoWork OS. 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 generate_narration_audio is rated High

This tool triggers an external voice/TTS service to produce audio output. It executes an operation against a configured external service and produces an artifact (MP3 file). It's not purely a read operation, nor does it delete data, move money, or simply write structured data — it invokes a media generation pipeline, placing it in Execute.

RECOMMENDED RULE

The rule that runs generate_narration_audio safely

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

generate_narration_audio Rate-limited

generate_narration_audio 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.
