Get Latest Earnings Call

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is known. The description adds minimal context beyond that, such as that only the most recent transcript is returned, and does not describe error behavior or availability. This is a reasonable baseline given annotations cover the key safety 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?

The description is one short, front-loaded sentence that immediately states the action and object. Every word is useful, with no filler or redundancy.

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 is simple with one well-documented parameter and helpful annotations. The description adequately states the result (the most recent earnings call transcript). However, with no output schema, it could optionally clarify the transcript format or behavior when no transcript exists, leaving minor room for improvement.

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 single required parameter 'identifier' is fully documented in the schema with examples (ticker, CIK, CUSIP, or ISIN), achieving 100% schema description coverage. The tool description does not add any parameter details, so the baseline score of 3 applies.

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 the most recent earnings call transcript for a company. The phrase 'most recent' differentiates it from sibling tools like get_earnings_call_transcript and list_earnings_calls, giving a specific verb, resource, and scope.

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 explicit usage guidance is provided. The description does not mention when to prefer this tool over get_earnings_call_transcript or list_earnings_calls, nor does it state any prerequisites or alternative conditions. The intended use is only weakly implied by the tool name and 'most recent' phrasing.

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