get_testers

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

With no annotations, the description carries full responsibility for disclosing side effects. It says 'Get', implying a read-only operation, but does not explicitly state that no modifications occur. It also does not mention potential error cases or rate limits, but for a simple getter, this is acceptable. The lack of explicit side-effect disclosure is a minor gap.

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 succinct, using two short sentences. It states the purpose and the key constraint without any unnecessary words. Structure is clear and easy to parse.

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 simple getter with no output schema, the description provides sufficient context: what it does, the condition (closed track), and the return concept (googleGroups). It lacks details on error behavior or fallback defaults, but these are not critical for this type of tool. Overall, it is adequately complete.

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 schema covers both parameters with descriptions (100% coverage). The description adds context about the track being closed and the return type (googleGroups), but these are partly redundant with the parameter descriptions. No significant additional semantics beyond the schema are provided.

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 states the tool's function: retrieving Google Groups for a closed testing track. It uses the verb 'Get' and specifies the resource (Google Groups) and scope (closed testing track). While it doesn't explicitly contrast with the sibling 'update_testers', the read-only nature is implicit in 'Get'.

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 provides a clear usage constraint: it only applies to closed tracks (alpha and custom tracks), not to internal or production. This helps the agent decide when to invoke the tool. However, it does not explicitly mention when to use an alternative like 'update_testers' for modifications, though the read-only implication is strong.

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