finnhub_stock_estimates

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

Without annotations, the description lacks behavioral details such as rate limits, authentication needs, or side effects. It mentions JSON export but no other traits.

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?

Two sentences, efficient. However, the second sentence has formatting issues (double period) and could be more streamlined. Still concise overall.

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?

The tool lacks output schema and annotations. The description does not specify return structure, pagination, or data freshness, leaving significant gaps for an agent.

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 description adds value by explaining the 'export' parameter's purpose (force export) and listing operations, but the schema already covers 75% of parameters. No additional syntax or constraints beyond schema.

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 provides analyst estimates and recommendations, listing specific operations. It distinguishes from sibling tools by focusing on analyst 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?

No guidance on when to use this tool vs alternatives like finnhub_stock_fundamentals. The description does not specify prerequisites or context for usage.

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