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

The description adds value by advising to 'Include the conversation array with recent messages for reproduction,' which is a useful behavioral hint for the user. It does not contradict annotations (readOnlyHint=false, idempotentHint=true, destructiveHint=false). It could disclose more about side effects (e.g., where the report goes), but the annotation already covers safety, and the description contributes meaningful context beyond that.

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 sentences, front-loaded with the primary purpose and a single, actionable hint. There is no redundancy or filler. Every word earns its place, making it highly concise and well-structured.

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's simplicity (3 simple parameters, no output schema, no nested objects), the description is mostly adequate. It captures the core purpose and the key hint about conversation, but it fails to explain the 'context' parameter and does not describe what the tool does after reporting (e.g., success/failure behavior). This incomplete parameter explanation reduces completeness, though the tool remains usable for an agent.

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 clarifies the 'conversation' parameter (by suggesting to include it for reproduction) and indirectly the 'message' parameter (as the content of the report). The 'context' parameter remains unexplained, and the default values are not described. This leaves a significant portion of the input schema unambiguated, so the description fails to fully fulfill the responsibility.

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 is a specific action with a clear resource (the subject of the report), and it distinguishes from sibling tools like authenticate or show_version which serve entirely different functions. The verb 'report' is explicit.

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 communicates when to use the tool ('Report a bug, missing feature, or send feedback') but does not explicitly mention alternatives or when not to use it. Since sibling tools are all unrelated, this is not a critical gap, but the lack of any exclusionary guidance prevents a perfect score. The context is clear and implied usage is accurate.

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