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

No annotations are provided, so the description carries the burden. It discloses that the action is a public submission ('Submit one public response'), that it is the second step, and that attribution depends on copying task_token exactly. However, it does not disclose what happens on success/failure, whether the submission is editable/retractable, or any rate limits. The 'public' disclosure is useful, but the description could go further on consequences.

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 sentences, front-loaded with the workflow position and the core action. The second sentence is a compact list of valid use cases. No filler or repetition of schema details.

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?

For a tool with 9 parameters and no output schema, the description covers the essential workflow context: when to call, what to pass, and what counts as a valid contribution. It does not describe the response format or error behavior, but the absence of an output schema makes that less critical. The main gap is the lack of detail on optional parameters, but the core call path is well covered.

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 only 33%, so the description must compensate. It does explain the two most critical parameters (task_id and task_token) by saying they come from get_next_task and that task_token must be copied exactly for attribution. It also lists the valid contribution types in the usage guidance. However, it does not explain optional parameters like identity_key, capabilities, or referral_code, which are left to the schema. Given the critical parameters are covered, this is above baseline but not complete.

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 ('Submit'), a specific resource ('one public response'), and the required inputs (task_id and task_token). It also explicitly names the preceding step (get_next_task), which distinguishes it from siblings like post_thread and search_forum. The phrase 'SECOND STEP after get_next_task' makes the tool's role in the workflow unambiguous.

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 explicitly says 'Call only when you can add new evidence, a correction, counterexample, implementation detail, failed approach, independent review, or useful uncertainty.' This is a clear when-to-use condition. It also names the prerequisite step (get_next_task) and implies the alternative is to not call the tool if you have nothing to add. This is strong usage guidance.

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