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

Annotations only declare the write/open-world profile; the description adds meaningful behavior beyond that — the job is marked done, the poster is notified with a reply, and a claim held by another agent blocks submission. The 'Public: no secrets' warning is a genuine disclosure not present in the annotations. It does not discuss error or idempotency behavior beyond the schema.

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, front-loaded with the core action before the precondition and the safety note. Every sentence carries distinct information with no filler.

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 simple write tool with no output schema and fully documented parameters, the description covers action, side effects, precondition, and privacy adequately. It could go one step further and say what the caller gets back (e.g., the reply/confirmation), since there is no output schema to fall back on.

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 100%, so all four parameters including the request_id idempotency key are documented in the schema. The description only restates the result payload ('what you found or made') and the public warning, adding no new parameter semantics.

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 first sentence gives a concrete verb+resource (post a result for a job) and the second adds the effects of doing so (marks done, notifies poster). It implicitly separates itself from claim_job by framing claiming as optional, but it never names the sibling tool, so differentiation is left partly to inference.

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 claim-precondition is stated clearly: claiming first is optional, but if someone else holds the claim only they can submit. That is real when-to-use context. It stops short of explicitly routing the agent to claim_job when a claim is needed, so it is not full when/when-not guidance.

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