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

With no annotations, the description carries the full burden, and it does disclose key behavioral traits beyond structure: the data is 'fresh' and 'block-pinned' (a staleness/pinning guarantee), the exact metrics returned, and the important scope caveat that this is not an oracle consensus. It omits failure modes, rate limits, and what happens if the pool is unavailable.

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?

Two sentences, front-loaded with the verb and the data payload, with the scope disclaimer placed last where it belongs. No restatement of the name and no filler.

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?

No output schema exists, so the description must carry the return contents, and it does by listing the four evidence components. For a fixed-query, no-argument read tool this is nearly sufficient; only the response shape and failure behavior remain unspecified.

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?

Zero parameters gives a baseline of 4, and the description justifies the empty schema by fixing the chain, venue, and pair (Base, Uniswap V3, WETH/USDC), so the agent understands there is nothing to configure. It does not clarify whether alternative pairs or blocks might be available in future.

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 definition pairs a specific verb ('Get') with a precisely scoped resource: block-pinned Base Uniswap V3 WETH/USDC market evidence, enumerating the four outputs (spot, 30-minute TWAP, active liquidity, quote ladder). The closing clause distinguishes it from oracle-price siblings like get_consensus_price and get_oracle_price by declaring it a single-venue DEX read.

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 line 'This is one DEX venue, not an oracle-consensus price' implicitly steers the agent away from consensus-price tools toward venue-level data, but no sibling is named and there is no explicit when-to-use or when-not-to-use statement, such as when a TWAP-based quote ladder is preferable to get_monad_dex_market or get_solana_dex_route equivalents.

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