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

No annotations are provided, so the description carries full responsibility for disclosing behavioral traits. It only says 'search' and 'find targeted news' without mentioning pagination, date range behavior, output format, or any operational details beyond what’s in the schema. This is a significant gap for a tool with no annotation safety profile.

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 two sentences, front-loaded with the core purpose and free of unnecessary words. Every word earns its place, making it appropriately concise and well-structured.

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?

With no annotations, no output schema, and five parameters, the description is minimal but not entirely insufficient. It states the purpose and key usage, but it does not disclose how pagination or date filters affect results, or what the response looks like. This is adequate for a simple search tool but has clear gaps.

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%, with each parameter described. The description adds no extra semantics beyond mentioning 'symbols' as the entry point. Per the baseline rule, a 3 is appropriate when the schema does the heavy lifting.

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 function: searching forex news for specific currency pairs. The verb 'Search' and resource 'foreign exchange news' are specific, and 'targeted news on specific currency pairs' adds scope. However, it does not explicitly distinguish from sibling tools like getForexNews, so it loses the top score.

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 phrase 'Find targeted news on specific currency pairs by entering their symbols' gives a clear context for when to use this tool (symbol-driven search). No explicit alternatives or exclusions are mentioned, but the use case is clear enough for a 4.

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