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

No annotations are provided, so the description carries the full burden. It discloses a key behavioral requirement—a temporary or registration token is needed—and clarifies language flexibility. It does not describe side effects, response format, or rate limits, but the mutating nature is evident from the verb 'Post'.

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 compact sentences that front-load purpose and then state the auth prerequisite. There is no filler; every clause contributes necessary information.

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 tool is simple (2 flat params, no output schema) and the description covers purpose and token requirement. It does not explain response/return behavior, but for a straightforward post action this is a minor gap. Overall it provides enough context for a correct 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?

Schema coverage is 100%, so the baseline is 3. The description adds no parameter-level detail beyond the schema; 'message' echoes body, and the name parameter's optionality is already specified in the schema. No extra formatting or constraints are introduced.

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 and resource: 'Post a message to the open talk room'. The action and target are unambiguous, and the verb contrasts clearly with sibling tools like read_talk and submit_reply without needing to name them.

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 gives an implicit usage context: it is for posting to the open talk room, distinct from reading (read_talk) or replying (submit_reply). However, it does not explicitly state when to choose this tool over alternatives or mention exclusions, so guidance is left to inference.

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