get_earnings_calendar

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

With no annotations provided, the description carries the full burden of disclosing behavior. It only states it 'gets' data, implying a read operation, but does not mention authentication, rate limits, data freshness, or any side effects. For a simple retrieval tool, more context on behavior would improve transparency.

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 a single sentence that concisely conveys the tool's purpose without extraneous words. It is well-structured and captures the core functionality efficiently.

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 tool has an output schema and only two optional date parameters documented in the schema, the description is sufficient for understanding the core functionality. However, it lacks usage guidelines and behavioral details, making it only moderately complete for an AI agent to invoke without additional context.

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%: both parameters ('from_date' and 'to_date') already have descriptions in the input schema, including defaults. The description adds no further semantic meaning beyond the high-level purpose, so the baseline score of 3 is appropriate.

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 retrieves global corporate earnings release events, actual/estimate EPS, and revenue surprises. It uses a specific verb ('Get') and resource ('earnings calendar'), and the content differentiates it from sibling tools like get_dividends_calendar or get_economic_calendar.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention context such as prerequisites or typical use cases. It only states what the tool does, offering minimal decision support.

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