cast_abi_encode

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only states the core function without detailing traits like error handling (e.g., what happens if arguments don't match the signature), encoding format (e.g., hex output), or whether the operation has side effects. The minimal description adds little 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 a single sentence – concise but overly minimal. It front-loads the key action, but lacks structure (e.g., no breakdown of steps, no examples). It is not wasteful, but it could be more informative without sacrificing conciseness by adding a brief usage hint.

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?

Given the complexity of ABI encoding and the lack of an output schema, the description is incomplete. It does not explain the return format (e.g., hex-encoded bytes), potential errors from mismatched types, or how to handle edge cases. Parameter definitions are covered in the schema, but the description should provide more operational context.

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 both parameters ('signature' and 'args') are described in the schema with clear definitions. The description adds no additional meaning beyond what the schema provides. According to guidelines, baseline is 3 when coverage is high, and this score reflects that.

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 the tool's purpose: 'ABI-encode values for a given Solidity function/constructor signature'. It uses a specific verb ('ABI-encode') and resource ('values for a given Solidity function/constructor signature'), and the name 'cast_abi_encode' distinguishes it from siblings like 'cast_abi_decode' and 'cast_calldata_decode'.

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 does not provide explicit guidance on when to use this tool versus alternatives. It lacks context such as prerequisites, typical use cases (e.g., preparing calldata for a contract call), or when to use sibling tools like 'cast_abi_decode'. A brief example of a signature is given but it does not help in decision-making.

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