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

With no annotations, the description carries the burden of behavioral disclosure. It provides useful content context ('recent trades, asset ownership, transaction details') and implies a read-only retrieval, but it does not mention pagination behavior, response format, data freshness, or any limits. This is partially transparent but not fully.

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 primary purpose, and every clause adds relevant context about the resource and intended use. There is no wasted words or redundant repetition of parameter details.

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 two-parameter list tool with no output schema, the description provides an adequate high-level overview but omits important details like what 'latest' means, how pagination works, or the structure of returned results. It is minimally viable but not fully complete.

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 schema already fully describes both parameters (page and limit) with clear descriptions, and the tool description adds no additional parameter-level semantics. Given 100% schema_description_coverage, 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') and a clear resource ('latest financial disclosures from U.S. Senate members'), and explicitly names the FMP API. This distinguishes it from closely related siblings like getLatestHouseDisclosures (House vs. Senate) and getSenateTrades (disclosures vs. trades).

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 the tool is for retrieving recent Senate financial disclosures, but it does not explicitly state when to use it over alternatives like getSenateTrades or getLatestHouseDisclosures. There is no when-not-to-use guidance or mention of sibling alternatives, so usage context is only implied.

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