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

No annotations exist, so the description must carry the burden. It mentions the return type (JSON array) and the constraint, but does not disclose safety (e.g., read-only), idempotency, or potential rate limits. The behavior is implied as safe, but not stated.

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 front-loaded with the purpose, followed by structured argument details. It is slightly verbose due to listing example values, but remains clear and functional without wasted sentences.

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 annotations and presence of an output schema, the description covers the core functionality, parameters, and return type. It also notes the constraint. Missing details like error handling or pagination but acceptable for a search tool.

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 description coverage is 0%, yet the description provides rich semantic context for all three parameters: query as free-text on name/ticker, country with list of UEMOA countries, and sector with specific sector names. This fully compensates for the missing schema descriptions.

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 specifies the tool searches BRVM-listed stocks by name, country, or sector, using precise verbs and distinct filtering dimensions. It distinguishes itself from siblings like get_company_info and list_tickers, which target specific data retrieval rather than search.

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 explicitly states 'At least one filter must be provided,' setting a clear constraint. However, it lacks explicit guidance on when to prefer this tool over siblings, e.g., searching by criteria vs. fetching details for a known ticker.

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