Search Companies By Sn Url

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

With no annotations, the description carries the full burden, but it only instructs 'Provide URL instead of filters.' It does not disclose what the tool does with the URL, whether it returns a list or single company, whether it is read-only, or any other behavior. This is close to no behavioral disclosure at all.

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 extremely short and front-loaded, but it is under-specified rather than efficiently complete. The single phrase 'Provide URL instead of filters' attempts a concise contrast, yet it omits context needed for correct invocation, so the brevity is not fully appropriate.

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, no annotations, and no details about how to provide the URL or what the search returns. An agent cannot reliably determine how to invoke this tool, what input to supply, or what result to expect, making the description inadequate even for a low-complexity tool.

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 description says to provide a URL, but the input schema has zero properties, so there is no URL parameter an agent can populate. This creates a mismatch between the instruction and the structured contract. While 0-parameter tools normally need little parameter documentation, here the description adds misleading semantics instead of useful meaning.

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 title and description imply that this tool searches for companies using a Sales Navigator URL rather than search filters, but the description never states an explicit verb and resource ('Searches for companies using a company SN URL'). It hints at the purpose through 'Provide URL instead of filters' but does not clearly differentiate from the sibling get_company_by_url.

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 phrase 'instead of filters' gives some contextual clue that this tool is for URL-based input rather than filter-based search, which weakly distinguishes it from search_companies. However, it provides no explicit when-to-use guidance, no exclusions, and does not mention relevant alternatives such as get_company_by_url or get_company_by_domain.

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