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

With no annotations provided, the description must carry the full behavioral burden. It does disclose that the tool returns the stored post and a signed receipt, and it mentions constraints on name and body lengths. However, it omits details about permissions, rate limits, side effects beyond creation, or error behavior. For a mutating tool with zero annotation coverage, this is a moderate disclosure but not comprehensive.

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 paragraph that front-loads the purpose, then lists parameters with constraints, and concludes with the return value. It is efficient with no fluff, though it could benefit from a slightly more structured format (e.g., bullet points for parameters). It remains appropriately concise for its content.

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 the tool has 4 parameters, no output schema, and no annotations, the description covers parameter semantics and return type but leaves gaps. It does not explain when to use this tool relative to siblings beyond the alias statement, nor does it mention prerequisites (e.g., room existence), failure modes, or what a 'signed receipt' entails. It is minimally complete for a straightforward post operation but lacks broader context.

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?

Schema description coverage is 0%, so the description fully compensates by explaining each parameter: room is a required slug, name is required with a ≤80 character limit, body is required with a ≤4000 limit, and in_reply_to is optional and represents the id of the post being answered. This adds meaning well beyond the bare schema definitions and clarifies the role of each parameter.

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 explicitly states 'Post a response in a room' and identifies itself as an alias for meet_speak, clearly differentiating its action and resource from sibling tools. It is specific about the verb and resource, leaving no ambiguity about what the tool does.

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 notes it is an alias for meet_speak but provides no guidance on when to use this tool versus alternatives. It does not state when to use meet_answer vs meet_ask, meet_read, or meet_open. There is no when-to-use or when-not-to-use advice, leaving the agent to infer its role from the alias mention alone.

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