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

No annotations exist, so the description carries full behavioral burden. It usefully lists the result fields (agency, dates, comment deadline, docket, links), implying a read-only search, but discloses nothing about auth, rate limits, pagination, or what the default 365-day window implies.

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 sentences, front-loaded with the operation and a compact field list, followed by a short use clause. No filler, though the field enumeration is dense and could be trimmed.

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?

An output schema exists, so return-value explanation is unnecessary, and the purpose is adequately conveyed. The remaining gap is input-side: the undocumented days/limit/doc_type parameters leave an agent guessing about scope and filtering.

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% across 5 parameters. The description never explains q, days (the lookback window), limit (result cap), agency, or doc_type, and does not indicate valid doc_type values. Field names appear but map to outputs, not inputs, so it barely compensates for the schema gap.

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 gives a specific verb (Search) and resource (US federal rules, proposed rules, notices, presidential documents) and enumerates the fields returned. It does not, however, distinguish itself from closely related siblings like sec_full_text_search or us_federal_awards.

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?

'Use to track US regulation on a topic' supplies a usage context, but there are no explicit when-not conditions and no alternatives named (e.g. SEC filings vs. federal register), so routing must be inferred.

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