congress_committee_senate_communications

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

The readOnlyHint annotation already signals this is a safe read operation, so the description's job is lighter. The description adds the committee scoping constraint but does not disclose other behavioral aspects such as pagination or the shape of the returned data. This is adequate but not rich beyond the annotation.

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 a single sentence of 11 words, front-loaded with the verb 'Get' and the resource. Every word contributes to understanding, with no redundancy or filler.

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 this two-parameter read-only list tool, the description and schema together provide enough context to invoke it. There is no output schema, so a hint about the response format would be helpful, but the tool's name and the phrase 'Senate communications' make the expected return type reasonably inferable. Slight room for improvement in describing the output.

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 100% coverage for both parameters, including descriptions for committee_code (with an example) and limit (default/max). The description adds no additional parameter semantics, so the baseline of 3 applies.

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 uses a specific verb ('Get'), identifies the resource ('Senate communications'), and includes the scoping qualifier ('referred to a specific Senate committee'), which clearly distinguishes it from sibling tools like congress_senate_communications that likely return all communications. This is a precise and unambiguous purpose statement.

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 clearly implies when to use this tool—when you need Senate communications for a particular committee—and the scoping makes it obvious that it is not the general Senate communications tool. However, it does not explicitly name alternatives or provide 'when not to use' guidance, so it falls short of full usage guidelines.

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