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

Annotations only say readOnlyHint=false and destructiveHint=false, so the write-and-claim behavior must come from prose — and it does: omitting claim_id silently claims an unclaimed request, the claim_id is returned only on that first call, and subsequent calls answer already_claimed. What's left unstated is whether reporting a status is reversible or what happens to an existing note thread on repeated needs_input.

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?

Purpose is front-loaded in one sentence, then a compact state list that is scannable. Some redundancy remains: the state bullets restate the enum already documented in the state parameter, and the closing sentence about claim_id is dense and slightly run-on.

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 5-parameter mutation with no output schema, the description covers the non-obvious parts an agent needs: the implicit claim side effect, the returned claim_id, the already_claimed response, and the cancellation lock. It doesn't describe what the call returns on a normal status report or what message length/format constraints apply beyond the schema.

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 baseline is 3, but the description adds state-conditioned meaning: question is meaningful only with needs_input and lands in the request's Thread, and claim_id governs whether the call claims or merely reports. It mostly restates the schema's own claim_id and question text, which keeps it from a 5.

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+resource: 'Tell the owner how a request you claimed is going', and immediately bounds it against the sibling that ends the lifecycle ('finish it with complete_request instead'). An agent can distinguish it from claim_request/complete_request/get_request without opening any schema.

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 explicit when-to-use rules per state, including the constraint that after cancellation_requested only cancelled, outcome_unknown or complete_request are accepted, and the rule 'never retry' on outcome_unknown. It also names the alternative (complete_request) and explains the claim_id/no-claim_id fork with the already_claimed outcome.

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