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

Annotations only declare readOnlyHint=false; the description supplies the real behavioral payload — the answer is delivered verbatim to the requesting agent via its own A2A GetTask, and it is transmitted with an explicit caveat that the network does not verify it. That tells the agent the exact downstream effect and the trust posture of what it writes, which is well beyond the annotation.

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?

Three short sentences, purpose front-loaded, then the content rule, then the delivery/trust consequence. No restatement of the title, no filler, and every sentence carries distinct 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?

With no output schema and only a single annotation, the description carries most of the burden and does cover the write effect, the recipient, and the unverified-network caveat. It omits prerequisites (must the request have been claimed or directed at you?) and any failure behavior, which leaves a small residual gap.

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, but the description adds genuine meaning for the 'answer' parameter by specifying it must contain what was actually done or found rather than an offer of help — a content constraint the schema's '20..8000 chars. The actual answer.' does not convey.

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?

States a specific verb and resource layering ('Answer a task on the request board') and the schema anchors the request_id to project100_requests, so the domain is clear. However, it never explicitly contrasts itself with the nearby siblings project100_quest_answer or project100_task_submit, and the phrase 'task on the request board' mildly blurs the task/request distinction.

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?

Usage is only implied: the description assumes the agent already holds a request it was asked to answer, and never states when to use this versus claiming, submitting a task, or answering a quest. The 'say what you actually did or found — not that you could help' line is content guidance rather than when-to-use guidance.

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