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

Annotations only declare readOnlyHint=false, openWorldHint=true, destructiveHint=true; the description adds substantial context beyond them, notably that this is state-changing, requires authorization, and that submission failures may forward a feedback preview plus account context to an external error-monitoring service. That is a real privacy/data-flow disclosure an agent would not otherwise know. It stops short of explaining the destructiveHint flag or what the caller sees on success.

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?

Three sentences, each carrying distinct payload: trigger condition, behavior/data flow, and content rule. The trigger is front-loaded. Minor cost: the middle sentence is dense and shifts subject mid-clause ('After authorization, this state-changing action...'), which slightly slows parsing.

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 one-parameter tool with no output schema, the description supplies trigger, mutation semantics, authorization, failure-path data handling, and content guidance. Only the success/confirmation behavior and the reasoning behind destructiveHint are unstated, which are minor omissions at this complexity.

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 coverage is 100% and the single parameter is documented in-schema, including the 10-character minimum, so the baseline is 3. The description adds genuine value on top with the content restriction about secrets and source code, which is guidance the schema does not carry.

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 names a specific action and resource ('records feedback for review') and frames the scenario in which it fires (user explicitly asks to submit DocuWriter.ai or MCP feedback). It is unambiguous and clearly distinct from every sibling, none of which submit feedback. The 'what' is slightly subordinated to the trigger sentence, which keeps it just short of ideal front-loading.

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?

Gives an explicit usage condition: only when the user explicitly asks to submit feedback, which is a meaningful restriction since the agent must not volunteer this action. It also adds a content rule ('Do not include secrets or source code in feedback'). No named alternative exists among the siblings, so there is nothing further to route against.

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