get_sol_price

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 implies a read-only operation ('Fetch') but does not mention any behavioral details such as return format, potential delays, rate limits, or whether it requires authentication. For a simple read tool this is acceptable but not comprehensive.

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 sentence, highly concise with zero filler. It is front-loaded with the key verb and resource. Every word earns its place.

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?

Given the simplicity of the tool (no parameters, no nested objects, no output schema), the description is largely sufficient. However, it does not specify the exact return value (e.g., numeric price, string representation, or whether it includes historical data), which could leave slight ambiguity. Still, for a straightforward price getter, it is adequate.

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 tool has zero parameters, and the schema coverage is trivially 100%. Per rubric, 0 parameters yields a baseline score of 4. The description adds no parameter details, but none are needed.

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 'Fetch current SOL/USD price' with a specific verb ('Fetch') and resource ('SOL/USD price'), distinguishing it from sibling tools like get_token_info or get_pool_liquidity. The purpose is unambiguous and directly maps to the tool's name.

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 context for when to use this tool is obvious: whenever the user needs the current SOL/USD price. Since the tool has no parameters and a unique niche among siblings, no exclusions or alternatives are necessary. It is implicitly clear, though not explicitly expressed.

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