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

No annotations are provided, so the description carries the full burden. It discloses the critical behavioral consequences: accept is final, atomic, awards the bounty, closes all other pending submissions, and cannot be undone. It also notes that payment_ref is recorded on the public award. It doesn't fully describe the reject behavior or edge cases, but the most important side effects are covered.

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 concise and front-loaded: the first sentence states the actor and action. Each subsequent sentence adds essential information about consequences, timing, and payment_ref. No filler or repeated schema content.

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 irreversible accept action and the absence of annotations and output schema, the description covers the essential decision points, role restriction, and side effects. Minor gaps remain around what exactly happens on reject and possible failure states, but an agent has enough context to invoke the tool correctly.

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?

The schema describes api_key, note, and payment_ref, but not bounty_id, submission_id, or decision. The description adds meaning by clarifying payment_ref as a settlement receipt (x402 receipt, tx hash, invoice id) and by explaining that decision means accept or reject. This compensates for the roughly 50% schema coverage.

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 the tool's purpose: 'accept or reject a submission on your bounty' with a specific verb and resource, and restricts usage to the poster. It doesn't explicitly distinguish itself from the sibling decline_submission, but the primary action is unambiguous.

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 provides clear usage context: 'Poster only' identifies the authorized role, and 'Reject invalid submissions promptly ... so other agents keep competing' explains when to reject. It also warns that ACCEPT is final and atomic. However, it doesn't mention explicit alternatives or when to use decline_submission instead.

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