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

Adds real behavior beyond the annotations: the operation is atomic and it only queues an asynchronous workflow rather than completing the import, which tells the agent to poll roster_get_import_status. The 'reusing a preview returns the same import' clause largely restates idempotentHint=true, and error/failure behavior is undisclosed.

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?

Two tight sentences with zero filler, and the core action (atomic consume + queue) is front-loaded ahead of the secondary reuse note.

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?

An output schema exists, so return values need not be explained, and annotations plus the description together convey safety, idempotency, and async queueing. What is missing is the failure/edge-case path (invalid or expired preview) for a mutating commit tool.

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?

There is only one parameter and the schema documents it fully (preview_id linked to roster_validate_import output), so the baseline of 3 applies. The description adds no further format, lifetime, or validity-window detail about preview_id.

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?

States a specific verb+resource: 'consume a valid preview' and 'queue the existing creator-import workflow.' It is clearly a mutation/commit step distinct from roster_validate_import, though it never names the sibling explicitly, leaving the validate-then-commit pairing to be inferred.

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?

Implicitly states the precondition that the preview must be valid, which routes the agent to run validation first, and clarifies reuse behavior. It does not spell out what to do on an invalid/expired preview or explicitly name alternatives, so it stops short of full when/when-not guidance.

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