Company Funding

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

With no annotations provided, the description carries the full behavioral burden, yet it discloses nothing about authentication, rate limits, error behavior, or whether both parameters are optional (required count is 0). Only the verb 'Get' implies a read operation; 'comprehensive' hints at breadth but is not concrete behavior.

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 first sentence is front-loaded and informative, but the second sentence is generic promotional filler rather than guidance, so it does not fully earn its place. Overall the description is short but partially wasted.

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?

No output schema and no annotations exist to offset the description, which leaves unresolved how the two identifier parameters are used (and which to prefer), what the response contains beyond a list of categories, and any behavioral constraints. For a research/data-retrieval tool this is under-specified.

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 description coverage is 0% and neither parameter (company_name, company_domain) is mentioned in the description. The description adds no meaning, syntax, or guidance on how the two identifiers relate or what happens when both are omitted, leaving a genuine gap for a 2-parameter tool.

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 ('Get') with a concrete resource ('funding information, financials, competitors') tied to the tool name, so the agent knows it retrieves company funding data. However, it does not differentiate itself from a sibling like search_company, which plausibly overlaps in scope, and 'company insights' is a vague catch-all.

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 second sentence ('Essential for investment research, competitive analysis, and business intelligence') lists broad use cases but never says when to use this tool versus alternatives such as search_company, nor any prerequisites or exclusions. This is marketing framing rather than actionable routing guidance.

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