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

With no annotations provided, the description carries the full behavioral burden. It discloses the conversion rate (1 USDC = 100 credits), the on-chain verification step, and the required prior deposit. It does not list failure modes or whether a tx_hash can only be claimed once, but for a simple claim tool it provides meaningful behavioral context beyond the name.

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 compact and front-loaded, with the core action in the first sentence. The additional workflow, conversion rate, and parameter notes each add necessary value with no filler or repetition of schema information.

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 tool has only two required parameters and an output schema, so the description doesn't need to explain return values. It provides the prerequisite workflow, the conversion rate, and clear parameter semantics, leaving no obvious gap for an agent to invoke the tool correctly.

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 must compensate. It does so fully: tx_hash is explained as a Base blockchain transaction hash with the 0x... format, and did is explained as 'Your agent's DID to credit.' This is exactly the semantic meaning missing from the input schema.

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 opens with a specific verb and resource: 'Claim MolTrust credits from a USDC deposit on Base.' It clearly identifies both the action and the source, and it is distinct from sibling tools like moltrust_deposit_history or moltrust_deposit_info because it focuses on the redemption action rather than viewing deposits.

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 gives an explicit prerequisite: 'After sending USDC to the MolTrust wallet on Base (L2), submit the transaction hash to receive credits.' This tells an agent when it is appropriate to call the tool. It doesn't explicitly name alternative tools or exclusion cases, but the deposit-claim flow is unambiguous enough that no misleading alternatives exist.

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