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

The description goes well beyond the readOnlyHint/destructiveHint annotations. It discloses the replay methodology, the use of actual V3 Swap events, the live forty-minute window, the per-width outputs, the absence of impermanent loss modeling, and the trade-off warning that IL is worst where fees are best. This gives the agent meaningful behavioral expectations without contradicting the annotations.

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?

The description is longer and more narrative than necessary for a two-parameter tool. The first sentence contains useful context but is padded with phrases like 'the decision concentrated liquidity actually forces.' Still, each sentence contributes substantive information about behavior, outputs, limitations, and the time window, so it is not wasteful enough to warrant a 2.

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 no output schema, the description does a decent job conveying what the tool returns: fees per candidate width, in-range duration, and exit count. However, it never explains how candidate widths are specified or what exact set of widths is considered, which is a meaningful gap for an agent trying to interpret or request results. The temporal window and lack of IL modeling are covered, but the overall contract remains somewhat 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?

The input schema already covers both parameters at 100%, so the baseline is 3. The description adds some context by tying 'stated size' to capitalUsd and mentioning pool/token address pining, but it does not explain parameter formats or defaults beyond what the schema states. The phrase 'per candidate width' introduces a concept not reflected in the schema, which slightly reduces clarity.

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 clearly states this tool helps a liquidity provider choose a PRICE RANGE for a PancakeSwap V3 pool by replaying real swaps and computing fees, in-range time, and exits. It distinguishes itself from modeling/forecasting tools by explicitly saying 'This does not model and does not forecast,' though it does not name a specific sibling alternative.

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 opening sentence gives a clear use case: a liquidity provider who has already picked a pool and now needs to decide on a price range. It also implicitly says when not to use it for forecasting or impermanent loss analysis. It does not explicitly compare to alternatives like pancakeswap_fee_tiers or pancakeswap_best_route, but the situational framing is reasonably clear.

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