solana_token

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

With no annotations, the description carries the burden of behavioral disclosure. It does add meaningful context by stating the tool is pay-per-call at $0.002 USDC and that data is live, which goes beyond a generic fetch. However, it does not mention error behavior, rate limits, or what happens for invalid mint addresses.

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 extremely concise: one clause states the returned data and input scope, and one clause states the cost. There is no redundant or filler content, and the most important information is front-loaded.

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 one-parameter read-style tool with no output schema, the description covers the input, the returned fields, and the cost model. It does not describe response format or failure cases, but the tool's low complexity and the description's directness make it largely complete.

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 schema already documents the single 'mint' parameter as an SPL token mint address. The description adds only 'any' and 'Solana' context, which does not materially improve understanding beyond the schema. A baseline of 3 is appropriate.

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 the resource (Solana SPL token mint) and the data returned (price, liquidity, 24h volume, DEX pairs), which clearly distinguishes it from the account, transaction, health, and trending siblings. It lacks an explicit verb like 'get' or 'fetch', but the intent is unambiguous.

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?

No guidance is given about when to choose this tool over the sibling tools. The phrase 'for any Solana SPL token mint' implies the input condition, but there is no explicit when-to-use, exclusions, or reference to alternatives such as solana_account or solana_trending.

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