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

With no annotations, the description fully carries the transparency burden. It discloses the fee-first call ordering, atomic submission via EIP-5792, the required follow-up confirm_mint_fee call, and the consequence that unconfirmed fee obligations block future mints. These are substantial behavioral traits that an agent needs to know.

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 description is two sentences, dense with necessary information. It front-loads the primary action, then explains the output format and required follow-up. No redundant or filler content — every clause serves a purpose.

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?

The description covers the essential workflow: input values, output bundle structure, submission order, atomicity requirement, confirmation step, and blocking behavior. It lacks minor contextual details like fee calculation basis or program activation prerequisites, but given the absence of output schema and annotations, it is highly complete.

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 input schema already provides descriptions for all parameters (100% coverage). The description mentions 'purchase amount' and 'cashback rate' but does not add new semantic detail about parameter formats or constraints beyond what the schema states. It meets the baseline for fully covered schemas.

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 clearly states 'Calculate and mint loyalty tokens based on purchase amount and program's cashback rate' — a specific verb and resource. It further distinguishes itself from the similar sibling tool 'mint_loyalty_tokens' by detailing the fee-first calls bundle, making the tool's unique behavior clear.

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 provides clear step-by-step instructions (submit bundle, then call confirm_mint_fee) but does not explicitly contrast this tool with alternatives like mint_loyalty_tokens. It implies usage context through the workflow description but lacks explicit 'when to use vs. when not to use' guidance.

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