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

With no annotations, the description carries the full burden and does disclose real behavioral traits: a 2-hour claim window, a per-caller cap of 2 open claims, and an emitted token required by submit_job. It omits what happens if the job is already claimed or whether the claim is exclusive/locking, which matters for a contention-prone operation.

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, zero filler, with the core action and the consumer of the token front-loaded. Every clause earns its place.

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 2-param mutation with no annotations and no output schema, the description covers the essential contract: duration, cap, and the token consumed by submit_job. Missing failure/exclusivity behavior keeps it from being fully complete.

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 50%: agent is self-described, but job_id has no schema description. The description implies job_id refers to an open job (linking to list_jobs) but adds no format or sourcing detail, so it only marginally compensates for the gap.

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 (claim) and resource (open job) with scope (2 hours) and return value (claim token for submit_job). An agent can distinguish this from list_jobs and submit_job 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?

Names the intended caller ('Contractors') and the downstream handoff to submit_job, which gives clear context for when this applies. It does not state exclusions or that job ids should first come from list_jobs, so it stops short of 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.
