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

With no annotations provided, the description carries the full burden of disclosing side effects. It explicitly warns 'This may cause a financial action when funding is enabled', which is a material behavioral disclosure beyond what the title implies.

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?

Two sentences with no filler: the action is front-loaded and the financial warning follows immediately. Every word contributes useful meaning.

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 single-parameter confirmation tool, the description covers the core action, the precondition, and the key risk. It does not detail error behavior or explicitly route among siblings, but those are minor gaps relative to the tool's simplicity.

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 provides no description for quote_id and schema coverage is 0%. The description partially compensates by referring to a 'previously returned quote', implying that quote_id comes from an earlier response, but it never explicitly ties the parameter to that origin or explains its format.

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 states a specific verb and resource: 'confirm a previously returned quote'. It also clarifies the consequential purpose, 'begin configured funding', which distinguishes it from siblings like get_outcome, request_outcome, and resume_outcome.

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 'previously returned quote' establishes the expected precondition: this tool follows a quote-generation step. It clearly implies the right moment to call it, though it does not explicitly name alternatives or state when not to use it.

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