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

The annotations already declare readOnlyHint=true and openWorldHint=true, so the description does not need to restate safety. It does add useful context: the data source is DexScreener and the tool costs 0.25 USDC. However, it does not describe what happens with no token filter, any external dependency behavior, or what the output looks like.

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?

Three short sentences, front-loaded with the core purpose, followed by cost and disclaimer. There is no fluff or repetition; every sentence carries distinct information.

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 simple read-only tool with one optional fully-documented parameter, the description is nearly sufficient, but it leaves key gaps: 'desk pins' is undefined, the return value is not described despite no output schema, and there is no hint about how a token filter is supplied. It is adequate for invoking with no arguments, but not fully self-contained.

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 description coverage is 100% for the only parameter, token, which is already documented as an 'Optional token filter'. The description adds no additional meaning about token format, allowed values, or how filtering behaves, so it provides no value beyond 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?

The description identifies a resource ('DexScreener liquidity digest') and an intended audience ('desk pins'), but it uses no explicit verb and never states what the digest actually contains or what the agent can do with it. 'Digest' restates the tool name and the 'desk pins' context is unexplained, so the purpose is only vaguely clear.

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 guidance about when to use this tool instead of a sibling such as pm_digest or token_meta, and no exclusions or alternative conditions are given. The cost '0.25 USDC' is a fact, not usage guidance, and 'Not financial advice' does not help an agent decide when to call it.

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