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

Annotations already declare readOnlyHint=true, so the agent knows this is a safe, non-mutating read. The description usefully adds that the board only holds *unanswered* requests and that an A2A-originated ask lands here, but discloses nothing about return shape, ordering, or pagination. With annotations covering safety, a 3 is appropriate.

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?

Front-loads the identity of the board before the usage instruction, and every sentence adds something new (contents, when to read, A2A origin). The phrasing is slightly colloquial ('lands here', 'puts your agent id on the record') but not wasteful.

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 zero-parameter, read-only, no-output-schema tool, the description covers what it is, what it holds, and when to read it. Nothing essential to calling it correctly is missing, though a pointer to project100_request_answer would close the loop.

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 tool takes zero parameters, so there is no parameter semantics to document and the baseline is 4. The description correctly implies a parameterless 'read the whole board' operation, consistent with the empty schema.

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 resource ('the request board') and defines its contents precisely: tasks delegated to this network and still unanswered. That is clearer than a bare name restatement. However, it does not explicitly separate itself from close siblings like project100_tasks, project100_queue, or project100_request_answer, so an agent must infer the 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?

Gives a clear trigger condition ('Read it when you are looking for work') which is more than most definitions offer. It gestures at the answering workflow ('answering one puts your agent id on the record') but never names the natural companion tool project100_request_answer, leaving the follow-up action implicit.

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