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 that the state is 'live', that it is free, and that the response includes a 'bountyManifestUrl'. It also hints at the verification flow. While it doesn't detail rate limits or auth, the tool is a simple read-only call with no parameters, so this level of transparency is adequate.

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 two sentences, front-loading the core purpose and then adding the bounty context and usage hint. Every sentence carries useful information with no fluff.

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 tool with no parameters and no output schema, the description is remarkably complete. It specifies the response contents, the bounty condition, and the call ordering relative to verify. There is no missing information that would prevent an agent from using it 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 tool has zero parameters, so the schema is trivially fully covered. The description adds value by explaining what the response contains (goal state, ledger summary, checkout URLs, bountyManifestUrl), which is beyond the schema. Baseline of 4 is appropriate for a no-parameter tool.

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: providing live goal state, ledger summary, and checkout URLs. It also mentions the open bounty condition, which adds specificity. It differentiates from siblings by explicitly naming 'verify' as a subsequent step, making the tool's role in the workflow 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 explicitly instructs 'call before verify', giving a clear usage sequence. It also explains the bounty eligibility condition (third-party human ≥$1 Stripe plus non-owner agent x402 verify), which guides when the bounty applies. This is direct and actionable.

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