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

With no annotations provided, the description should disclose safety and behavioral traits. It clearly indicates a read-only retrieval operation ('Access', 'Retrieve'), which implies no side effects. However, it does not explicitly state read-only status, pagination behavior, or any potential limitations, leaving some burden on the agent.

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 main purpose, and contains no fluff or redundant information. Every word adds value, making it highly concise and easy to parse.

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?

For a simple list tool with two optional parameters and no output schema, the description adequately explains the return content (list of companies and transcript counts). It does not describe pagination details or response format, but the complexity is low enough that this is sufficient. Could be more complete by mentioning it returns 'latest' transcripts.

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?

Input schema coverage is 100% because both parameters (page, limit) have descriptions. The description itself adds no additional parameter semantics beyond what the schema already provides, 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 uses a specific verb ('Access', 'Retrieve') and names the resource ('FMP Latest Earning Transcripts API') and the output ('list of companies with earnings transcripts, along with the total number of transcripts'). This is distinct from siblings like getEarningsTranscript (which likely fetches a single transcript) and getEarningsTranscriptList (which may list transcripts without counts), so it clearly differentiates.

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 implies when to use this tool (when you need the list of companies and transcript counts), but it does not explicitly state alternatives or when not to use it. There is no mention of using other transcript tools instead, so guidance is only implicit.

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