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

No annotations are supplied, so the description carries the full behavioral burden. It does add genuine context about the caller's OpenAny gateway credentials and that charging/authorization are gateway-determined, but it never clarifies whether this merely returns encoded calldata or actually broadcasts a transaction — the single most important fact for a 7702 wallet 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?

Three short sentences, purpose front-loaded, no filler. The second and third sentences are generic gateway boilerplate rather than tool-specific detail, but they are brief and not redundant.

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?

This is a complex tool — nested call objects with chain enums, a 7702 delegation address — with no output schema and no annotations. The description should say what comes back (encoded calldata, typed data, or a submitted transaction) and what constraints apply; it covers none of that.

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 baseline of 3 applies; all nested fields (calls, walletAddress, smartContractDelegationAddress) are structurally defined. However, the description adds no meaning about what the required `calls` array or the delegation address represent in a 7702 encode flow, and the schema's own field descriptions are only placeholder names.

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?

"Encode wallet transactions" gives a verb and resource, but in a namespace full of Uniswap swap/7702 tools it is under-specified. It never mentions EIP-7702, delegation, or why an agent would need encoding rather than the sibling uniswap_post_v1_swap_7702, which also targets 7702 wallets.

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?

There is no when-to-use guidance: nothing says whether this is a prerequisite step before a 7702 swap, an alternative to uniswap_post_v1_swap_7702, or how it relates to uniswap_post_v1_wallet_check_delegation. The only contextual sentence is about transport ("native public Uniswap HTTP contract"), not selection.

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