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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds that these are 'canonical' addresses with named chain coverage, which is genuinely useful behavioral context, but it says nothing about whether results are static/cached or how missing chains are represented.

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?

A single compact sentence-fragment that front-loads the resource and then enumerates chains, with no filler. It could be tightened into a full clause stating it returns addresses, but nothing is wasted.

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 zero-parameter, read-only lookup with an output schema already describing the return shape, the description covers what an agent needs: what contracts, which chains, which extras. A brief note on how to use the returned addresses (e.g. as the target for prepare_uniswap_* calls) is the only real gap.

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?

The tool takes zero parameters, so per the baseline there is no parameter semantics for the description to carry and the schema has nothing to document. Nothing in the description misleads about inputs.

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 names the exact resource: canonical V2/V3/V4 contract addresses, plus Permit2 and wrapped native tokens, and enumerates the supported chains. It is a noun phrase with no verb, so the retrieval action comes from the tool name rather than the description, but the scope is specific enough to distinguish it from address-returning siblings like get_aerodrome_deployment.

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 or when-not-to-use guidance, no mention of prerequisites, and no routing hint toward the sibling deployment tools (get_aerodrome_deployment, get_lido_deployment, get_morpho_vaults) for other protocols. The agent must infer that this is the address-book lookup to consult before preparing Uniswap transactions.

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