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

Annotations provide idempotentHint=true and destructiveHint=false, which the description does not contradict. The description adds the requirement to include conversation data, but does not disclose other behavioral traits like authentication or response format. With annotations, the description adds some value but is not comprehensive.

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 very concise with two sentences. The first sentence front-loads the purpose, and the second adds a crucial usage hint. Every sentence is earned, and no wasted words.

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 params, no output schema), the description covers the main purpose and a key usage hint. However, it omits details about the 'context' parameter, expected message format, and what the user will receive as a response. For a feedback tool, this is minimally acceptable but not fully complete.

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 explicitly mentions including the 'conversation array,' which clarifies that parameter. However, it does not explain 'context' or 'message' beyond their names. Since 'message' is self-explanatory and 'context' is optional with a default, the description adds moderate value.

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.' The verb 'report' and resource 'bug/feedback' are specific, and the sibling tools are all openfinance-related, making differentiation easy.

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 usage guidance: 'Include the conversation array with recent messages for reproduction.' It implies when to use (for feedback) and what to include, but does not explicitly state when not to use or mention alternatives. However, sibling context makes the usage clear.

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