chat_sendStateRecording

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

With no annotations provided, the description carries the full burden. It discloses the 25-second duration and that the recording is simulated, but it does not explain side effects, whether the state can be canceled, or what happens after the duration ends.

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 short but contains redundancy, repeating 'Simulate recording audio' in the first and second sentences. It could be condensed to a single sentence without losing meaning, but it is not overly verbose.

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?

The description covers the core function and duration, which is adequate for a simple state-simulation tool. However, with no output schema and no annotations, it lacks details on return values, termination behavior, or potential side effects, so completeness is moderate.

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 provides 100% coverage for both parameters (chatId and sessionId) with descriptions and examples. The tool description adds no additional parameter semantics, so it stays at the baseline for full schema coverage.

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 states a specific verb ('Simulate recording audio') and resource ('chat'), with a defined duration of 25 seconds, making it clear what the tool does and distinguishing it from sibling state tools like chat_sendStateTyping.

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 usage is implied: the tool is used to simulate an audio-recording state in chat. However, it does not explicitly mention alternatives (e.g., chat_sendStateTyping) or provide when-not-to-use guidance, so the agent must infer context.

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