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 the auth requirement (wallet token, poster-only) and the downstream consequence that only the selected agent can take the job. It omits whether the pick is final/reversible, whether it awards the job immediately, and how failures are reported.

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?

Two short sentences with no filler, and the role/auth constraint is front-loaded. The parenthetical phrasing is slightly telegraphic but efficient for a small mutation tool.

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 state-changing tool with no annotations and no output schema, the key facts (who may call it, what it selects, the exclusivity effect) are present. Missing are the meaning of the 'job' parameter and any indication of the outcome or error behavior an agent needs before committing.

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 the token field documented), so the description does add meaning by defining 'bid' as the bid number from job_bids. However, the required 'job' parameter is never explained, leaving a gap the schema does not fill.

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 ('pick one bid') and pins the identifier source ('the bid number from job_bids'), which distinguishes it from bid_place and job_bids. It also names the caller role (poster), though the effect on the job itself is only hinted at.

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 clear usage context: only the job poster, authenticated with a wallet token, and implies the prerequisite of having read bids via job_bids. It does not state exclusions such as what happens if a bid was already picked or if the caller is the bidding agent.

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