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

The description transparently states it is a 'Destructive state-changing action' that 'marks the pending suggestion discarded directly after authorization.' This goes beyond the destructiveHint annotation by specifying the exact effect and timing.

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 concise at two sentences, front-loaded with the primary use case, and clearly structured with the action, effect, and requirement.

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 simple single-parameter input and no output schema, the description provides all necessary context: when to use, what it does, the destructive nature, and the source of the required ID. No additional information is needed.

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?

The schema already covers the parameter with a clear description and 100% coverage. The main description reinforces this with 'Requires suggestion_id from list-space-suggestions,' adding practical guidance on sourcing the ID, but does not exceed the schema significantly.

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 action: 'reject, dismiss, remove from review, or discard one ... suggestion'. It specifies the resource as a documentation suggestion and distinguishes from siblings by emphasizing 'one' suggestion, contrasting with bulk or snooze operations.

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?

Explicitly says 'Use this when the user wants to reject, dismiss, remove from review, or discard one...' and provides a prerequisite: 'Requires suggestion_id from list-space-suggestions.' It does not explicitly mention alternatives like bulk or snooze, but the word 'one' implies the scope.

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