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

Annotations already declare this is a non-destructive read operation, and the description adds useful behavioral context: pending means transaction_hash is null and the recipient has not been credited, completed means the mint was recorded, and /balance remains 0 until confirm. This is meaningful state semantics beyond the annotations, though it does not cover auth or return-shape behavior.

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 purpose is front-loaded in the first sentence, followed by compact status definitions and one balance note. The description is short, structured, and every sentence contributes useful interpretation.

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 read-only list tool with 100% schema coverage and annotations covering safety, the description gives enough context to understand pending versus completed mints. It does not describe the return shape or pagination, which is a minor gap given there is no output schema.

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 coverage is 100%, so the baseline would be 3, but the description adds real meaning to the status filter by defining pending and completed in transactional terms. The optional token_address parameter is left to the schema, so this is not a 5.

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: it lists mint intents scoped to the merchant. It is clearly distinguishable from action-oriented siblings like mint_loyalty_tokens and balance-oriented siblings like get_token_balance, though it does not explicitly name alternatives.

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 usage by explaining what pending and completed mean and that GET /balance stays 0 until confirm, which helps an agent interpret results. However, it does not explicitly say when to choose this tool over siblings or mention any when-not conditions.

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