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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the return of structured intelligence and a price, but does not state whether the tool is read-only, has side effects, requires authentication, or how it behaves on errors. This is a significant gap for a tool that likely makes external API calls.

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 front-loads the core action and form types, then appends the agent name and price. It is concise with no redundant wording, though the inclusion of the agent name and price adds minor clutter. Overall it earns a 4 for efficiency.

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 tool with no output schema and no annotations, the description is insufficiently complete. It does not explain what 'structured financial intelligence' means, what fields are returned, or how errors are handled. Given the tool's complexity (three parameters, no output schema), an agent would need more detail to invoke it reliably.

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%, so the schema already documents ticker, question, and filingType with descriptions. The description adds no extra meaning beyond the schema; it merely references the forms which are already enumerated. According to the baseline, a score of 3 is appropriate when the schema does the heavy lifting.

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 analyzes SEC filings (10-K, 10-Q, 8-K) and returns structured financial intelligence. It names a specific verb and resource, and the forms distinguish it from siblings like search_13f_whale_filings. However, it doesn't explicitly contrast with other analysis tools, so it falls short of a 5.

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 usage for SEC filings by listing the form types, but provides no explicit guidance on when to use this tool versus alternatives such as search_13f_whale_filings. There are no 'when not to use' or 'use instead' statements, leaving the agent to infer context from sibling names.

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