ring_initiate_whep_stream

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states that a streaming session starts and that an SDP offer is exchanged, but it does not disclose whether the tool returns an SDP answer, whether the stream must later be terminated, or what side effects the live stream has on the camera.

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?

The description is a single sentence with the core action front-loaded and no redundant filler. It loses a point because the 'or name' claim is unnecessary and inaccurate, and the sentence is slightly awkward in how it joins 'by ID or name' with 'exchanging a client SDP offer.'

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?

This is a state-changing protocol tool with no output schema and no annotations, so the description should explain what the caller receives and what lifecycle obligations exist, such as receiving an SDP answer or terminating the stream later. Those details are absent, leaving the description incomplete for reliable invocation.

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?

The input schema already fully documents both deviceId and sdpOffer, so the baseline is 3. However, the description's claim that the camera can be selected 'by ID or name' actively conflicts with the schema, which provides only deviceId and describes it as a unique device ID, potentially misleading an agent into passing a camera name.

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 names a specific action ('Start'), a concrete resource ('live WebRTC WHEP video streaming session with a Ring camera'), and the method (exchanging a client SDP offer), making it clearly distinct from list/status/termination siblings. It is not a perfect 5 because the phrase 'by ID or name' is unsupported by the schema, which only accepts deviceId.

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?

The description implies this tool should be used when an agent needs to initiate a live WHEP stream and has a client SDP offer. It does not explicitly state prerequisites, such as obtaining the deviceId via ring_list_devices, nor does it point to ring_terminate_whep_stream as the way to stop the session.

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