search_spectrum

Read-only

Find spectrum band holders by frequency range. Filter by agency, direction, polarization, or applicant name to identify allocations.

Instructions

Find which entities hold a frequency band. Given a range in MHz, returns spectrum allocations overlapping it, joined to the source filing and applicant — e.g. 'who is allocated 11700-12200 MHz downlink?'. Filter by agency, direction, polarization, or holder name.

Behavior3/5

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

The description is consistent with the readOnlyHint annotation, but it does not disclose additional behavioral traits such as pagination, rate limits, or data freshness. It adds minimal context beyond what annotations already provide.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise: two sentences with no wasted words. The first sentence immediately states the purpose, and the example reinforces usage efficiently.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and 7 parameters, the description adequately explains inputs (range) and outputs (allocations joined to filing and applicant). It could mention default limit but is otherwise complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All 7 parameters have descriptions in the schema (100% coverage), so the description adds little new semantic value beyond contextualizing freq_low_mhz and freq_high_mhz as a range. The schema already handles parameter meaning.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states the tool finds entities holding a frequency band and returns spectrum allocations. It provides a clear example and distinguishes from sibling tools which cover different domains (e.g., satellites, filings).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage via the example and listing of filter options, but it does not explicitly state when to use this tool over alternatives or provide exclusions. Usage is clear but not comprehensive.

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