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

Without annotations the description carries the full burden, and it does add real value: it warns that HTTP success is not on-chain completion, and that credentials, charges, and authorization come from the caller's OpenAny gateway. It still omits whether the returned plan is idempotent, whether plan IDs expire, or whether any signing/submission step is required, so it is informative but incomplete.

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?

Four short sentences, front-loaded with the action and followed by the transport, the stateful caveat, and the billing/credential note. No filler, though the "native public Uniswap HTTP contract" sentence contributes little to tool selection.

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 deeply nested quote-shaped body with no output schema and no annotations, the description does not say what the response contains (plan ID, transactions/steps) or how it links to uniswap_get_v1_plan_planid. The lifecycle caveat is helpful but the end-to-end flow an agent needs remains underspecified.

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 the nested body/quote/gasStrategies structure is documented structurally, and the baseline of 3 applies. The description adds nothing about the body payload, routing values, urgency, or the x-agent-info header, leaving all parameter meaning to the 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?

States a specific verb and resource: "Create an execution plan." An agent can tell this is a planning/creation endpoint, but the description never contrasts it with the closely named siblings uniswap_post_v1_quote, uniswap_post_v1_swap, or uniswap_get_v1_plan_planid, so the boundary between planning and execution must be inferred.

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 explicit when-to-use or when-not-to-use guidance, and no named alternative tool. The only directional hint is implied by "Tracks a multi-step execution plan; HTTP success is not proof of on-chain completion," which suggests this does not itself settle a trade, but the agent is not told to call quote first or to follow up with the plan-id endpoint.

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