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

Beyond the readOnlyHint/openWorldHint annotations, the description adds genuinely useful context: it states the on-chain read, names the default pool, and discloses the commercial terms ($0.003 in USDC per successful call, x402 via Base/Solana/Arc, failed calls not charged). This is exactly the kind of operational detail annotations cannot convey. It stops short of mentioning rate limits or pagination/windowing behavior beyond the words parameter.

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 payload of what is returned and back-loaded with the cost model. The first sentence is long and em-dash-chained but each clause names a concrete field. 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?

With an output schema present, the description needn't document return shapes, yet it still summarizes them, and it covers the pricing model and default pool. What is missing is explicit guidance on when to prefer this tool over the many other liquidity/market siblings, which is the main gap for a two-param tool in a crowded namespace.

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 baseline applies. The description restates the default pool and gestures at the tick window ('within a window around the price'), but the concrete meaning of 'words' (1–5, one word = 256 tick spacings) lives in the schema, not the description. It adds little semantic value beyond the structured fields.

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 opens with a precise verb+resource ('Uniswap V3 liquidity distribution for an Ethereum pool, read on-chain') and then enumerates exactly what is returned: tokens, fee tier, tick spacing, current tick and price, in-range liquidity, and initialized ticks. That level of specificity clearly separates it from nearby siblings such as crypto_dex_pool_liquidity or crypto_curve_gauge_weights.

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?

Usage is only implied: the reader can infer this is for inspecting concentrated-liquidity positioning at the tick level, and a default pool (USDC/WETH 0.05%) is supplied. But there is no explicit when-to-use versus when-not, and no sibling is named as an alternative despite several overlapping market/pool tools in the namespace.

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