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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=true, covering the safety profile. The description adds only the instruction to include the conversation array, which is more of a usage guideline than a disclosure of behavioral traits. It does not explain side effects (e.g., where the report goes) or clarify any implications of the idempotent hint. With annotations present, the description adds little extra transparency, so a 2 is fair.

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 with no filler. It front-loads the purpose and immediately follows with a practical usage instruction. Every word earns its place, making it exemplary in conciseness and structure.

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?

The tool is relatively simple (3 params, no output schema), and the description covers the main purpose and one key parameter. However, it omits what to include in 'message' (the actual bug description) and what 'context' is for. Given the schema already marks 'message' as required, the description could have added value by explaining these parameters, but it does not. It is minimally complete but leaves gaps, so a 3 is appropriate.

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 clarify parameter meanings. It mentions the 'conversation array' and that recent messages are needed for reproduction, giving some meaning to the conversation parameter. However, it does not explain 'message' or 'context'—even though message is required. This partial compensation is insufficient for a 3-param tool with no schema descriptions, resulting in a 2.

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 (bug/feedback). It distinguishes itself from siblings which are unrelated (authenticate, connect, etc.). However, it lacks the precision of the high-calibration example by not specifying any scope or target system, so a 4 is appropriate.

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 implicitly suggests when to use the tool (when reporting issues/feedback) and gives one usage hint: 'Include the conversation array with recent messages for reproduction.' It does not mention when not to use it or alternatives, but siblings are unrelated so differentiation is not critical. The guidance is minimal but not misleading, warranting a 3.

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