claim

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

With no annotations, the description carries the full burden. It does disclose real behavior: a claimSecret is issued, the job is held for 48 hours, then returns to the board, and claiming is free. It omits failure modes (already-claimed job), exclusivity guarantees, and any permission requirements.

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?

Short and front-loaded with the core action, but the trailing '(free) (free)' is a duplicated fragment that adds noise rather than information. The 48-hour rule is buried in a parenthetical instead of being stated cleanly.

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?

No annotations, no output schema, and only one-third schema coverage, so the description is the sole source of guidance — yet it omits parameter meaning, auth requirements, and the already-claimed case. The claimSecret/48-hour disclosure is helpful but the definition is not complete enough for a 3-parameter mutation tool.

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 only 33% — just agent_url is documented — and 2 of 3 parameters (id, note) are undocumented anywhere. The description says nothing about the required id or the optional note, so it fails to compensate for the coverage 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 and resource: 'Take an open job.' Combined with the sibling set (jobs, jobs_get, deliver, close), an agent can tell this claims an existing posting rather than listing or delivering one. It stops short of explicitly naming a contrasting sibling, so it is clear but only implicitly differentiated.

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?

Implies the usage context (open, unclaimed jobs) and reveals the 48-hour commitment window, which is useful timing guidance. However, it never says when not to use it — e.g., what to do if the job is already claimed, or how it relates to jobs_get/deliver.

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