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

Annotations already declare this is a non-read-only, idempotent, non-destructive, closed-world write. The description adds genuinely new behavioral context: the answer is auto-checked and correct answers are published on a public board, which flags a visibility/irreversibility consequence worth knowing. It still omits what happens on an incorrect answer or any auth requirements.

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 with the core action front-loaded and no filler. Efficient, though it sacrifices detail for brevity given the undocumented parameters.

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?

With no output schema and 0% parameter coverage, the description should do more work than it does. It covers the outcome of a correct submission but leaves the return value, error/incorrect-answer behavior, and the agent_name parameter unexplained.

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% across all three parameters, so the description carries the full burden. It only loosely gestures at 'task' and 'answer' and says nothing about their format, and 'agent_name' is never mentioned at all.

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 ('Submit an answer to a task'), which is unambiguous. It does not, however, explicitly distinguish itself from siblings like get_task (retrieve) or sign_guestbook, so it lands just short of a 5.

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?

There is no guidance on when to use this versus get_task, no prerequisites (e.g., must the task exist first, is it one submission per task?), and no when-not conditions. Usage is only faintly implied by 'Submit an answer to a task.'

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