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

No annotations are provided, so the description carries the full burden. It discloses that results are LLM-structured with importance scoring, which is valuable behavioral context. However, it does not describe the return format, pagination, or any other operational behavior, leaving gaps for a tool with no output schema.

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 no wasted words. It front-loades the core purpose and adds the key behavioral nuance (LLM-structured, importance scoring) succinctly.

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?

Given no output schema and no annotations, the description should explain return values and operational details. It covers the domain and a key output characteristic, but does not explicitly state what the tool returns or how results are paginated. The schema covers inputs well, but the description does not fully compensate for missing output information.

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?

The input schema provides full descriptions for all 9 parameters, so the baseline is 3. The description adds a high-level mention of signal types and materials, but this does not meaningfully enhance parameter understanding beyond the schema.

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 clearly identifies the tool's purpose: searching Federal Register regulatory signals on semiconductor-critical materials, with explicit signal types (export controls, sanctions, etc.). It distinguishes itself from sibling tools by focusing specifically on regulatory signals for materials, unlike funding, trade flows, mineral deposits, restricted entities, or SEC filings.

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?

The description implies is usage when a user needs regulatory actions on semiconductor materials, but it does not explicitly state when to use it over alternatives or provide exclusions. No alternative tools are mentioned, so the guidance remains implicit rather than explicit.

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