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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds useful behavioral context about the exact notice types and filterable attributes, but it does not mention pagination, result ordering, or return structure. With annotations bearing the safety burden, this is adequate but not exceptional.

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 focused sentences carry the full meaning: the first defines the resource and scope, the second lists the filter dimensions. There is no filler, repetition, or unnecessary detail.

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 read-only search tool with a fully documented schema and no output schema, the description provides enough context about what is searched and how to narrow results. It could add return-format or pagination notes, but the absence does not leave the agent unable to invoke the tool 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 100%, so the schema already documents each parameter. The description adds a high-level grouping of filters ('keyword, NAICS, agency, notice type, date') that help orientation but do not provide parameter-level detail beyond what the schema already offers. Baseline 3 is appropriate.

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 opens with a specific verb and resource: 'Search SAM.gov notices.' It then enumerates the notice types covered (Sources Sought, Pre-solicitations, solicitations, combined synopses), which clearly distinguishes this from sibling tools like search_awards or search_bills. The title reinforces the domain without ambiguity.

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 gives clear context by framing these notices as 'the earliest public signal of a purchase,' so an agent can infer this is the tool for pre-award opportunities. It does not explicitly name alternatives or say when not to use it, but the scope is specific enough that the intended use case is evident.

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