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

With no annotations, the description carries the full burden of behavioral disclosure. It adds useful context by indicating the data is SEC-sourced and the output is a compact overview rather than an exhaustive report, but it does not describe any limitations, caveats, or additional behavioral traits.

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 focused sentence with no filler. It front-loads the action and resource while including key qualifiers ('compact', 'sourced', 'SEC') that add meaning without bloating the text.

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 single-parameter read tool with an output schema, the description is reasonably complete. The main missing piece is explicit differentiation from closely related sibling tools, but the core mechanics and purpose are sufficiently conveyed.

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% and the single 'ticker' parameter already has a descriptive comment in the schema. The description adds no additional meaning about the parameter beyond confirming this is a company-level snapshot 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 clearly states a specific action ('Get') and a defined deliverable: a compact, sourced SEC company and financial overview. It conveys the tool's scope as an at-a-glance snapshot, though it does not explicitly differentiate it from siblings like research_company or financials.

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 wording 'compact...overview' implies this tool is appropriate when a concise company and financial summary is needed. However, it provides no explicit guidance on when to prefer it over siblings such as financials, research_company, or search_company, nor does it state any exclusions.

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