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

No annotations are provided, so the description carries the full disclosure burden. It usefully reveals that the outcome is a Stripe Checkout link (which substitutes for the missing output schema), but it does not state auth requirements for agent_key, whether the link is idempotent/expires, or that no funds move until the third-party checkout completes.

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?

A single front-loaded sentence with no filler; the verb, resource, and amount scope are all stated up front.

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 two-parameter mutation tool with no annotations and no output schema, the description covers the purpose and the return artifact (link) but leaves agent_key, auth/permission needs, and link lifecycle unaddressed. Adequate but with clear gaps.

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 does explain amount semantics ('whole-dollar', $10–$10,000), matching the multipleOf/min/max constraints, but it says nothing about agent_key, leaving one of two required parameters undocumented in both schema and description.

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 (Create) and resource (Stripe Checkout link for bounty-balance top-up), with scope (whole-dollar, $10–$10,000). It is clearly distinguishable from the sibling balance_get, which reads a balance rather than generating a payment link.

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 phrase 'bounty-balance top-up' implies the context in which the tool is used, but there is no explicit when-to-use guidance, no prerequisites, and no named alternative such as the supplier_checkout or supplier_payout siblings. Usage is only inferable.

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