encode_multisig_transaction

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It goes beyond a simple 'encodes' by specifying protective features (gas price caps, nonce protection, execution hashes) and an operational requirement (0.015 USDC on Base L2), which informs the agent about expected side-effects/costs. However, it does not mention output format, failure modes, or whether any external calls are made, which would be valuable for a transaction-encoding tool.

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, dense sentence followed by a parenthetical cost note. It front-loads the core function and key characteristics with no redundancy or filler. Every word adds value, and the structure is easy to scan for a quick understanding.

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 complex tool involving multisig transactions and payment, the description omits crucial information such as the expected output format, whether it performs network calls or just local encoding, error conditions, and how the payment signature is used. There is no output schema and no annotations to fill these gaps, so an agent may not know what to do with the result or how to troubleshoot failures. The description is too sparse to fully support correct invocation.

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 100%, so the schema already documents both parameters ('payload' and 'paymentSignature'). The description does not add parameter-specific detail beyond what the schema provides, but it does contextualize what the payload represents (multi-signature transaction payload batches). This meets the baseline for schema-heavy parameter documentation.

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 ('Encodes'), a specific resource ('Safe (Gnosis) multi-signature transaction payload batches'), and enumerates distinguishing features ('gas price caps, nonce protection, and execution hashes'). This clearly differentiates it from the many sibling tools, which are predominantly unrelated. The tool's purpose is immediately obvious without needing to inspect the schema.

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 the tool is used when someone needs to encode Safe multisig transaction batches, but it provides no explicit guidance on when to use it over alternatives, nor does it mention any exclusions or prerequisites. There are no sibling tools that seem similar enough to warrant a distinction, so the lack of explicit comparison is not a major flaw, but the absence of any 'use when' context leaves the agent to infer usage.

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