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

With no annotations, the description carries the full burden of disclosing behavior. It states the tool is a conversion and mentions 'Cost: 5 sats', but does not discuss error handling, data sources, or any side effects. The behavioral disclosure is minimal but adequate for a simple conversion 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 concise, including only relevant information (category, cost, endpoint, parameters). It is front-loaded with the purpose, and the parameter list is presented clearly. The inclusion of cost and endpoint adds context without bloating the description.

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 output schema exists, the description does not need to explain return values. However, the description leaves ambiguity about the JSON string requirement despite stating 'pass as JSON string'. The mismatch between description (required params) and schema (no required params) introduces confusion. Overall, it covers essential aspects but lacks full clarity.

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 input schema only has a generic 'params' string, providing no parameter details. The description adds meaning by naming the two expected parameters (bitcoin_price_usd, gold_price_per_oz) and marking them required, though this contradicts the schema which has no required fields. The description does not provide formats, examples, or constraints.

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 tool's verb ('Convert') and resource ('Bitcoin's USD price to equivalent gold ounces'), making its purpose immediately apparent. It is well-distinguished from siblings like 'd3p_btc-price' which focus on Bitcoin price in USD.

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 converting Bitcoin price to gold ounces, but lacks explicit guidance on when to use this tool versus alternatives (e.g., when you already have gold price in USD). No when-not-to-use or prerequisite information is provided.

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