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

Without annotations, the description discloses return format (sponsor record or error object), data source (DOL LCA), and the fact that it aggregates data. This is good transparency for a read-only tool.

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 concise sentences front-loaded with purpose. No unnecessary words; the ellipsis efficiently summarizes additional return fields.

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?

Adequately covers return structure, error handling, and data source. With a simple parameter and existing output schema, no further details are needed.

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?

With 0% schema coverage, the description adds crucial context by specifying the id comes from search_h1b_sponsors, which is beyond the schema. The single parameter's meaning is clarified.

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 it returns full details for one H-1B sponsor, referencing the id from a sibling search tool. The verb 'get' and resource 'sponsor details' are explicit, and the distinction from other get_* tools is evident.

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 using search_h1b_sponsors first to obtain the id, providing clear context. Does not explicitly state when not to use, but the context is sufficient for correct invocation.

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