company_filings

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

No annotations present, so description must cover behaviors. Lacks details on rate limits, pagination, data freshness, or error handling. Only states search capability and accepted identifiers.

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?

Two sentences, no filler. Front-loaded with purpose. Every word earns its place.

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?

Adequate for a simple search tool but lacks output format description, error cases, or special constraints. Could improve with typical response fields or date range treatment.

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 baseline is 3. Description adds minimal extra meaning (e.g., CIK as alternative) but mostly restates schema. No significant new insight.

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?

Clearly states the verb 'Search' and the resource 'SEC EDGAR company filings' with examples of form types (10-K, 10-Q, 8-K). Distinguishes from siblings by specifying SEC filings retrieval.

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?

Implies usage when company filings are needed, but provides no explicit guidance on when not to use or alternatives. No mention of prerequisites or context.

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