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

The description adds meaningful behavioral context beyond the annotations: the execution is asynchronous, it returns an operation ID, and the quote bounds spending. It also clarifies that submission is not the same as removal. No contradiction with annotations.

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?

Three compact sentences, front-loaded with the primary action, and every sentence adds value: async behavior, quote semantics, return handling, and scope distinction. No filler.

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 async execution tool with annotations covering idempotency and non-destructiveness, the description provides the key missing details: operation ID return and polling path. It is slightly incomplete on error/edge-case behavior but otherwise sufficient.

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 should compensate for the two parameters. It gives useful context about what a quote contains (spending bounds, rights scope/input), but it does not explain idempotency_key at all, leaving a required parameter underspecified.

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 action ('Execute a pre-approved prepare quote'), the resource, and the asynchronous nature. It also distinguishes from removal, which sets it apart from submit_takedown and related siblings.

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 implies when to use the tool: when a prepare quote is pre-approved, and instructs the agent to poll get_operation afterward. However, it does not explicitly state when to use this tool instead of submit_takedown or other alternatives.

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