testers_patch

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

With no annotations, the description should explicitly state behavior (e.g., idempotency, response). It only says 'partial update', which implies a write operation but lacks depth.

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?

A single clear sentence, concise but could be slightly expanded without becoming verbose.

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 4-parameter tool, the description is adequate but lacks return value specification. No output schema, so agent may not know what the call returns.

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 coverage is 75%, so most parameters have descriptions. The tool description adds no extra parameter meaning; the undocumented 'googleGroups' parameter is not elaborated.

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 'Partial update of the tester allowlist' clearly states the action (partial update) and the resource (tester allowlist), distinguishing it from the full update sibling 'testers_update'.

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 partial vs. full update or prerequisites like requiring editId from edits_insert. The agent must infer usage from context.

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