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

With no annotations, the description carries the full burden, and it does disclose some behavior: award starts the job, roles restrict actions, and withdraw refers to 'my proposal.' However, it does not explain the effects of close, whether actions are irreversible, or what happens to payments/proposals after awarding or closing.

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 a single scannable line that front-loads all five actions and their role constraints. It is efficiently compact, though slightly cryptic for actions like 'close' and 'withdraw my proposal' that would benefit from brief elaboration.

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?

This is a multi-action, state-changing tool with no annotations and no output schema, yet the description omits critical context: what close does, how id binds to a bounty, the purpose of turnaround_seconds, permission prerequisites, and expected results/errors. It is not complete enough for an agent to invoke every action confidently.

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 0%, so the description must compensate. It helpfully maps price/message/payment to propose and proposal_id to award, but it leaves id and turnaround_seconds unexplained, and not all actions have their parameter sets clarified. It adds meaning beyond the bare schema but does not fully cover seven 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 enumerates the exact actions available (propose, list_proposals, award, close, withdraw) and assigns them to specific roles (seller/owner), so the tool's purpose is concrete and unambiguous. It clearly sets this apart from sibling tools like create_bounty or job_action by framing the bounty/proposal lifecycle.

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 gives role-based usage context: propose/withdraw are for sellers, award/close are for the owner, and award explicitly 'starts the job.' It does not explicitly name alternative tools or say when not to use this one, but the action/role pairing provides clear selection guidance.

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