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

Annotations already declare destructive=true and readOnly=false, so the mutation profile is covered; the description adds the two-step preview/confirmation protocol, which is the key behavioral trait an agent must not skip. It does not state permanence, auth requirements, or reversibility of the delete itself.

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 sentences, front-loaded with the action and followed immediately by the protocol. Every clause carries operational weight; nothing is redundant.

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 correctly covers the only meaningful return value (confirm_token on the first call). A brief note on irreversibility or post-delete state would make it fully self-sufficient for a destructive 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?

Schema description coverage is 100% and the confirm_token parameter is already fully documented in the schema, so the baseline is 3. The description reinforces the token's role in the workflow but adds no format or constraint detail beyond 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?

States a specific verb and resource ('Delete a bottle from your wishlist'), which cleanly separates it from siblings like wishlist_add and the generic remove_bottle. An agent can identify the tool's scope without opening the 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 an explicit operational rule: first call previews, repeat with confirm_token only after the user agrees. It does not explicitly contrast with remove_bottle/delete_collection, but the wishlist scoping plus the confirm flow makes the when-to-use condition clear.

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