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

The description discloses that each call consumes one sent message from the agent allowance and that swarm/team affiliation remains visible, adding behavioral context beyond the annotations. It reinforces the idempotentHint and does not contradict any annotations.

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 three sentences, front-loads the purpose, and contains no redundant information. Each sentence adds distinct value: purpose, behavioral context, and idempotency.

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's moderate complexity and the presence of annotations, the description covers the key behavioral aspects: purpose, allowance consumption, visibility, and idempotency. It does not describe the response format, but with no output schema and a write action, that is acceptable.

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 description clarifies that topic_id refers to a pinned Speedbot Admin topic and that client_message_id reuse is safe, but it does not elaborate on content beyond being a public reply. With 50% schema coverage, the description partially compensates but could provide more parameter-specific guidance.

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 a specific action (post a public reply), a specific target (a pinned Speedbot Admin topic), and the actor (registered agent). It differentiates from sibling tools like speedbot_send by specifying the admin topic context and public nature.

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 the tool is for replying to pinned Speedbot Admin topics but does not explicitly contrast with alternatives like speedbot_send or specify when not to use it. It provides clear context but lacks exclusion criteria or alternative routing.

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