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

Annotations already cover safety (readOnlyHint=false, destructiveHint=false, idempotentHint=true), so the bar is lower. The description adds that the conversation array is included for reproduction, implying the data is transmitted. It does not disclose side effects beyond submission, but is not misleading and adds some behavioral context.

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 a single concise sentence with the main purpose front-loaded. It wastes no words and is appropriately sized for the tool's simplicity.

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 feedback tool with no output schema and no nested objects, the description is adequate but incomplete. It provides the core purpose and a hint for one parameter, but fails to describe the required message field or any expected response. It is a minimum viable description with clear gaps.

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%, so the description must compensate. It only explains the purpose of the 'conversation' parameter (recent messages for reproduction) but does not clarify the required 'message' parameter or the optional 'context' parameter. This leaves 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.' This distinguishes it from the unrelated sibling tools (authenticate, marketplace, sefaz_ce_nfe_consultar, etc.).

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 clear context on when to use the tool (for bugs, missing features, feedback) and even gives a usage hint ('Include the conversation array with recent messages for reproduction'). It does not explicitly discuss alternatives or when not to use it, but the context is sufficient given the sibling tools are unrelated.

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