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

The description adds significant behavioral context beyond annotations: it returns worker address and agreed price, automatically rejects other bids, and clarifies that no funds are held by the referee. This fully discloses side effects and data returned.

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?

The description is well-structured with a purpose statement, workflow hint, and returns section. It is slightly longer than necessary but every sentence adds value. The inclusion of the returns block is helpful.

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?

Given the tool's complexity (3 parameters, simple action) and the presence of an output schema, the description fully covers the workflow, side effects, and next steps. No gaps are present.

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?

Although schema coverage is 100% with clear descriptions, the tool description adds context by referencing source functions (e.g., 'from view_job() bids list' for bid_id, 'from post_job()' for job_id), which helps the agent understand how to obtain these parameters.

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 clearly states it accepts a bid and awards the job to a worker agent, with a specific verb and resource. It distinguishes itself from sibling tools like 'direct_hire' and 'submit_bid' by focusing on accepting bids.

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 explains when to use the tool (to accept a bid) and provides a clear next step (create_escrow_vault). It mentions that other bids are automatically rejected, but does not explicitly list conditions when not to use it or compare with alternatives.

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