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

Annotations are all false, so the description carries the burden. It adds useful context that this is an immediate claim using an ephemeral Guest Pass identity, which implies auth constraints. But it does not disclose side effects of claiming, whether the claim can be undone, or failure behavior if the task is already claimed or the token expires.

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?

A single front-loaded sentence with no filler. Every word earns its place: 'Claim' is the action, 'unpaid task' is the target, 'immediately' signals urgency, and 'ephemeral Guest Pass identity' states the authentication context.

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 two-parameter claim tool with a full schema and output schema present, the description is nearly complete. The main gap is that it does not explain how it relates to nexus_claim_task or describe the expected call sequence (start pass → claim → complete), which an agent might need when choosing among the many nexus_* siblings.

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 the baseline is 3 even though the description adds little parameter-level detail. The description's phrase 'ephemeral Guest Pass identity' loosely reinforces the guest_token parameter, and 'unpaid task' maps to task_id, but the schema already handles the specifics.

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 ('Claim'), a specific resource ('an unpaid task'), and a distinctive mode ('using the ephemeral Guest Pass identity'). This makes the tool's purpose immediately clear and distinguishes it from regular nexus_claim_task, though it does not explicitly name the sibling it differs from.

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 description implies the correct context: use when claiming an unpaid task with a Guest Pass identity. The schema reinforces this by describing guest_token as 'Short-lived token returned by nexus_guest_start_pass.' However, it never explicitly says when NOT to use this tool or when to prefer nexus_claim_task over the guest alternative.

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