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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the write-and-remove nature is partly pre-communicated. The description adds real value by revealing the composite effect: a card copy is created and the wishlist entry is dropped. It says nothing about reversibility, what happens if the card already exists in the collection, or failure modes.

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?

A single short sentence with the action and mechanism front-loaded; no filler, no redundancy. It is about as tight as a one-line definition can be.

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?

This is a destructive four-parameter mutation with no output schema and zero schema documentation, so the description carries most of the explanatory burden. It covers the high-level effect but leaves the parameter meanings, return behavior, and edge cases (duplicate copy, missing wish, invalid version/language combination) entirely unspecified.

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 0% and four parameters are completely undocumented. The description never mentions cardId, version, language, or condition, nor that the latter three likely describe the copy being added -- an agent can only infer that by cross-referencing add_card's 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 names a specific action on a specific resource ('move a wishlist card into the binder') and even discloses the underlying composition ('add_card + drop wish'), which lets an agent distinguish it from siblings like wishlist_remove and wishlist_add. It stops short of a 5 only because 'binder' is domain jargon that isn't tied back to the collection concept used by sibling names.

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?

Usage is implied by the name and the 'acquired' framing, and the parenthetical hints that this is a convenience wrapper over add_card plus wishlist removal, which is a useful steer. There is no explicit when-to-use statement, no guidance on when to call add_card and wishlist_remove separately, and no mention of preconditions.

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