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

Discloses the refund action and constraints, but no annotations provided. Lacks details on idempotency, error handling, or immediate vs. delayed refund.

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 redundancy. Information is front-loaded and efficiently presented.

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?

Covers most aspects for a simple operation, but missing details on the response (e.g., confirmation or refund amount). With no output schema, more context would be helpful.

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?

Only one parameter (iccid) with clear schema description. The tool description does not add additional semantic value beyond the schema, so baseline 3 is appropriate.

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?

Clearly states the action (cancel), resource (eSIM), and key condition (unused). It distinguishes from sibling tools like purchase_esim and topup_esim.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
