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

The description does not contradict annotations (idempotentHint true, readOnlyHint false). It adds that the conversation array is for reproduction, which gives some insight into behavior. However, it doesn't disclose potential side effects or data transmission, but with idempotentHint true this is less critical. Overall, minimal additional info beyond annotations.

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 concise, two sentences, front-loaded with the purpose. No fluff, directly tells what to do.

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 it's a simple tool with 3 params and no output schema, the description covers the main use but leaves 'message' and 'context' unexplained. It's adequate but not thorough.

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 description coverage is 0%. The description only mentions the 'conversation' parameter implicitly by saying to include itgang. It does not explain the 'message' or 'context' parameters. Given the low coverage, the description should compensate but fails to fully do so.

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: 'Report a bug, missing feature, or send feedback.' This uses specific verbs and resource, and it's distinct from all sibling tools which relate to Google Ads operations. It unambiguously identifies this as the reporting/feedback tool.

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 gives explicit guidance: 'Include the conversation array with recent messages for reproduction.' This tells the agent what to provide when using the tool. It doesn't explicitly say when not to use it, but since it's the only feedback tool among siblings, it's clear to use for bug reports/feedback. No exclusions stated, but context is given.

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