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

With no annotations, the description carries the full behavioral burden and delivers almost none of it: no statement that this is a read-only lookup, no auth/permission requirements, no rate limits, and no indication of what happens without an api_key. The only hint about behavior (statutory excerpt / audit report) lives in the schema's api_key field, not the description.

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?

A single front-loaded sentence with no filler or repetition. It is efficient, though the density of regulatory jargon ('eCFR', 'hurdles') costs a little interpretability for little gain in brevity.

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 two-parameter lookup tool with no output schema and no annotations, the description is only just adequate. It never states what the caller receives back (excerpts, determinations, citations) or how results should be interpreted, so an agent knows the topic but not the deliverable.

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 100%, so both parameters are already documented, including useful examples for 'query' (dual-use encryption, drone telemetry). The description adds no additional syntax, format, or scoping detail beyond the schema, so the baseline 3 applies.

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?

Names a specific verb ('Resolves') and a concrete resource set: statutory US import constraints, licensing regimes, and agency hurdles under eCFR. The import focus distinguishes it from screen_ofac_and_export_controls, but the description never explicitly draws that boundary, leaving an agent to infer it.

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?

No when-to-use guidance, no prerequisites, and no mention of the sibling tools. An agent cannot tell from this text whether to call this or screen_ofac_and_export_controls for a given product, nor when a free-key provision step is required first.

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