get_current_gold_rate

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

With no annotations, the description must fully disclose behavior. It states 'Get' and 'Returns', implying a read-only operation, but it does not mention any potential side effects, caching behavior, update frequency, or data source. The transparency is minimal and lacks depth.

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, consisting of two sentences that front-load the purpose. Every word contributes to clarity with no redundancy or unnecessary detail.

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 absence of parameters and output schema, the description provides sufficient context for a simple retrieval tool. It clarifies what the tool returns (latest rate per gram). However, it could be more complete by specifying the currency or unit explicitly.

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, so the description need not add parameter information. The baseline score of 4 is appropriate, as the description succinctly conveys the purpose without needing to elaborate on parameters.

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 the verb 'Get', the resource 'current gold rate per gram', and specifies that it returns the latest rate set by the store. It effectively distinguishes itself from the sibling tool 'get_gold_rate_history' by focusing on current versus historical data.

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 implies usage for retrieving the current gold rate, but it does not explicitly state when to use this tool versus alternatives like 'get_gold_rate_history'. No conditions or exclusions are provided, leaving the agent to infer context.

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