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

The description says 'Report a bug, missing feature, or send feedback,' which implies a side-effecting submission action. However, the annotations declare idempotentHint=true, suggesting repeated identical calls are safe and produce no additional effect. This is a contradiction: submitting the same bug report multiple times would plausibly create duplicate reports. The description also fails to disclose post-submission behavior or side effects beyond the schema.

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 two concise sentences. The first sentence front-loads the purpose, and the second provides a concrete usage instruction. Every word earns its place 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 a simple tool with no output schema and no nested objects, the description covers the basic action and one parameter, but it is incomplete: it omits the meaning of the required message parameter, does not explain context, and its behavior contradicts the idempotentHint annotation. The combination of incomplete parameter guidance and the annotation conflict makes the description insufficient for reliable agent invocation.

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?

With 0% schema description coverage, the description needed to explain all three parameters. It only addresses the 'conversation' parameter, noting it should contain recent messages for reproduction. The required 'message' parameter and the 'context' parameter are not explained at all, leaving significant semantic gaps.

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 purpose with a specific verb and resource: 'Report a bug, missing feature, or send feedback.' It is immediately distinguishable from all sibling tools, which are primarily Google Keep operations and authentication utilities.

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 makes the intended use context clear: use this tool when encountering a bug, missing feature, or when wanting to send feedback. It does not explicitly mention when not to use it or name alternatives, but no alternative feedback tool exists among siblings, so the guidance is sufficient.

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