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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description adds only 'confirm=true required', which duplicates the schema's required list, and it leaves a real ambiguity unresolved: whether 'remove a card' deletes only the wishlist entry or touches the card itself, and whether the removal is reversible.

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 short sentences, front-loaded with the action and the hard requirement. Nothing is wasted, but the terseness comes at the cost of substance rather than being tight prose.

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 a destructive, irreversible-sounding mutation with no output schema and zero parameter documentation, the definition is too thin. An agent lacks the information to distinguish this from wishlist_mark_acquired or to use the language parameter correctly.

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% across three parameters, so the description carries the burden and does not meet it. cardId is self-evident, but language is entirely undocumented and the purpose of confirm beyond a bare boolean (a safety gate) is never explained.

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 ('Remove a card from the wishlist'), which is clearly distinct from wishlist_add and list_wishlist. It does not explicitly disambiguate against wishlist_mark_acquired, which is a plausible confusion, so it stops short of a 5.

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?

There is no guidance on when to remove versus when to mark an entry as acquired, and no mention of prerequisites beyond the confirm flag. The only usage-adjacent content is a restatement of a schema requirement.

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