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

No annotations are provided, so the description carries the full burden. It discloses that the data is observed, from GeckoTerminal, and warns that high volume does not imply safety, adding meaningful behavioral context. The wording 'Observed trending' implies a read-only operation, though it doesn't explicitly state no side effects. This is adequate for a data query tool.

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 a single, compact paragraph that leads with the tool's purpose, lists return fields, adds a disclaimers about safety and financial advice, and ends with the limit parameter. Every sentence contributes information; there is no fluff, and it is well-organized for quick parsing.

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 read-only tool with one parameter and no output schema, the description is quite complete. It enumerates the return fields (name, mint, price changes, volume, liquidity, FDV, market cap, tx counts, pool age), names the source, and gives the limit range. It could mention that results are snapshots or time-dependent, but this is a minor omission; an agent has enough to call it correctly.

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 schema already fully documents the single parameter 'limit' with type, range, and default. The description repeats the limit info without adding new meaning. Since schema description coverage is 100%, the baseline of 3 applies; the description adds no extra semantic 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 names a specific resource (trending Solana tokens/pools), the ranking source (GeckoTerminal), and enumerates the exact fields returned. It also explicitly disclaims being a recommendation or prediction, which differentiates it from advisory siblings like solmachina_decision or solmachina_pretrade.

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 description states it provides market-activity facts and is NOT a recommendation or prediction, giving clear negative guidance. It does not explicitly name sibling tools or enumerate when-not-to-use conditions beyond the disclaimer, so it lacks explicit alternative routing, but the context is clear enough for an agent to know it is for observational data rather than decision support.

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