ssa_beneficiaries

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

Annotations already provide readOnlyHint: true, so the description's job is lighter. The description adds valuable behavioral context by stating that the tool returns links to downloadable datasets (not the data itself) and specifying the geographic breakdown (state, county, ZIP). This goes beyond the annotation and helps the agent set expectations.

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 exactly two sentences. The first sentence front-loads the action and subject, and the second sentence explains the output format and scope. Every word contributes; there is no redundancy or irrelevant 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 parameterless tool with a readOnly hint, this is complete. It states the data domain (OASDI and SSI), the output type (links to downloadable datasets), and the coverage (by state, county, and ZIP). No output schema exists, but the description adequately describes the return value. No further context is needed.

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 tool has zero parameters, so the baseline is 4. There are no parameter semantics to explain; the description is not lacking anything in this regard.

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 starts with 'Get SSA OASDI and SSI beneficiary data resources', providing a specific verb and resource. It further clarifies that the tool returns links to downloadable datasets by state, county, and ZIP code, which distinguishes it from other data-fetching tools and clearly communicates its function.

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 usage context: when one needs links to SSA beneficiary datasets by geographic area. However, it does not explicitly state when to prefer this tool over alternatives, nor does it mention any exclusions or when not to use it. The usage guidance is 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.
