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

No annotations are present, so the description carries the behavioral disclosure burden. It usefully discloses that only FCC radio licences are included, lists the return blocks, and says output is JSON. It does not describe match ambiguity, empty-result behavior, or whether any side effects occur, though the tool appears read-only.

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 two sentences with a clear colon-led purpose and a dense but purposeful list of return contents. Every phrase adds information and there is no filler.

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?

The output side is well specified, which matters because there is no output schema. However, with six parameters, no parameter descriptions, and no annotations, the missing filter semantics and absent sibling guidance leave an agent able to make a basic call but unsure how to use state, status, service, or include_expired correctly.

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%, so the description must compensate for the six parameters. It only indirectly covers company_name ('named company') and limit ('selected limit'), leaving state, status, service, and include_expired without semantic explanation beyond their schema patterns and defaults.

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 states a specific verb and resource: return the radio-licence footprint for a named company. The phrase 'Company enrichment' helps position it against the sibling tools and the output list is specific, but no sibling is explicitly named and the differentiation is left implicit.

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 guidance is given about when to use this tool versus fcc_search, fcc_stats, fcc_coverage, or the snapshot tools. The use case is implied by 'named company', but there are no exclusions or alternative routing cues.

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