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

Annotations already declare idempotency and non-destructive behavior, and the description adds useful semantics such as null removing collection membership or clearing fee, plus that the operation is free. It does not fully explain partial-update behavior or auth requirements, but with annotations covering safety it adds good context.

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 a single dense sentence that front-loads the meaningful operations and wastes little space. Each clause contributes specific update semantics.

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 an eight-parameter mutation tool with no output schema, the description covers the main editable fields and null behavior adequately, while annotations cover idempotency and safety. It could be stronger by clarifying sibling selection and partial-update semantics.

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 only 38%, so the description carries meaningful weight. It explains collection_id null semantics, ties fee to fee_basis, clarifies fee null clearing, and enumerates payout statuses, though it leaves account_id, uid, bearer_token, and idempotency_key largely to the schema.

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 states specific update actions for a tracked creator: collection membership, fee/payment settings, and payout status. It is clear what the tool does, though it does not explicitly differentiate itself from nearby siblings such as untrack_creator or manage_tracking_collection.

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 lists what can be changed but gives no explicit guidance on when to use this tool versus alternatives like untrack_creator or manage_tracking_collection. It also does not state when not to use it or what prerequisites apply.

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