stop_speaking

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses immediate silencing and safety when nothing is playing. Without annotations, it could add details like whether it cancels all queued TTS, but the current info is sufficient for a simple action.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with action and context. Every word earns its place; no unnecessary fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema or annotations, the description fully covers purpose, usage, and safety. It is complete for a zero-parameter stop action tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters exist, so schema coverage is 100%. The description adds no extra parameter info, which is appropriate; baseline score of 4 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool silences any in-flight TTS playback immediately, using a specific verb and resource. It distinguishes itself from sibling tools like speak_text or stop_recording by focusing on TTS.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly lists trigger phrases (stop, shut up, be quiet, interrupt) and notes it is safe to call when nothing is playing, providing clear guidance on when to use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
