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

No annotations, so the description carries the full burden. It usefully discloses cost ($0.001 per call) and the return fields, but says nothing about behavior for unknown, pending, or failed-to-index hashes, nor about error handling.

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?

One sentence, front-loaded with the price, then the resource, its input, and its output fields. No wasted words.

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?

With no output schema, the description compensates by listing the returned fields, and it discloses pricing. The only gap is that multi-chain support (network param) is left entirely to the 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% and the schema documents both hash and the network enum with default base, so baseline 3 applies. The description adds a bit of meaning via 'fee in native token and USD', hinting that values are chain-dependent, though it never mentions the network parameter itself.

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?

States a specific verb+resource (transaction receipt) with the key input (by hash) and enumerates the returned fields. This clearly distinguishes it from chain_block, chain_balance, and chain_token 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?

Usage is implied: call it with a transaction hash to get that transaction's receipt. No explicit when-to-use/when-not guidance or reference to alternatives such as chain_block is given.

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