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

Annotations declare destructiveHint=true and idempotentHint=true, and the description goes beyond them by disclosing the two-step preview/confirm protocol and the fact that deletion is permanent. That confirmation choreography is critical behavior an annotation cannot express.

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; the destructive nature is front-loaded and the confirmation sequence follows immediately. No redundant or filler text.

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?

With no output schema, the description still tells the agent what the first call returns (a preview and confirm_token) and how to proceed, so nothing needed to invoke this tool correctly is missing.

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 schema already explains both fields, but the description adds flow-level meaning: it clarifies that confirm_token is returned by the first call and that the retry must use identical arguments plus the token. Useful reinforcement rather than new syntax.

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 precise verb ('Permanently delete') and a scoped resource ('one of your bottles'), which separates it from nearby siblings such as remove_from_collection, delete_collection, and delete_my_activity without the agent needing to open a schema.

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 explicit procedural guidance: the first call previews only, the resulting preview must be shown to the user, and the repeat call happens only after user agreement. This is exactly the when-and-how guidance an agent needs for a destructive flow.

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