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

With no annotations, the description carries the full burden. It mentions the tool 'provides detailed information' but does not disclose behaviors such as optional date-range filtering (from/to), pagination, or error conditions. It doesn't contradict annotations (none provided), but it is thin on behavioral context.

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 and front-loaded with the core purpose. However, the phrase 'with the FMP COT Report API' is somewhat redundant, and the second sentence includes promotional language that adds limited value.

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?

There is no output schema and no annotations, so the description should compensate by explaining the return shape or date-range usage. It doesn't clarify the meaning of 'symbol' beyond the schema, or what a 'comprehensive' report includes. The presence of sibling COT tools makes this gap more significant.

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 input schema covers all three parameters (symbol, from, to) with descriptions, giving 100% coverage. The description adds no extra parameter semantics beyond what the schema already provides.

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 identifies the tool as accessing COT reports and describes the data content (long and short positions across sectors). While the verb 'Access' is a bit generic, the resource is specific and the description distinguishes it from sibling tools like getCOTAnalysis by focusing on reports.

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?

There is an implied use case for assessing market sentiment and tracking positions, but no explicit guidance on when to prefer this tool over getCOTList or getCOTAnalysis, nor any when-not-to-use scenarios.

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