get_testers

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

With no annotations, the description carries the full burden for behavioral disclosure. It states the operation is a 'get' (read), but does not explicitly confirm safety, lack of side effects, authorization requirements, or any constraints like rate limits. The description is too minimal for full transparency.

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 extremely concise, using two sentences for the main purpose and a short list for parameters. Every sentence adds value, with no redundancy or unnecessary words. It is well-structured and front-loaded.

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 the tool has no output schema, the description should indicate the return structure (e.g., a list of emails and groups) or any error conditions. It only names the outputs vaguely. Additionally, it omits any context on prerequisites (e.g., app must exist) or edge cases, making it incomplete for an agent to use confidently.

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?

Despite 0% schema description coverage, the description adds meaningful detail: example for 'package_name' and clarification of allowed values and default for 'track'. This compensates for the schema's lack of descriptions, though it could be more exhaustive (e.g., format constraints).

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?

Description clearly states the tool retrieves tester emails and Google Groups for a specific track, using a specific verb ('Get') and resource ('testers for a track'). It distinguishes from sibling 'update_testers' by its read-only nature, and the parameter documentation clarifies the scope (internal or alpha).

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?

No guidance on when to use this tool versus alternatives like 'update_testers' or 'list_tracks'. The description does not specify prerequisites, limitations, or conditions for use, leaving the agent without context for tool selection.

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