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

Annotations already declare destructiveHint=true and idempotentHint=true, and readOnlyHint=false. The description adds that authentication is required, which is useful but not extensive. It does not contradict annotations, but it doesn't disclose additional behavioral details like permanence or error behavior.

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 two short sentences, immediately stating the action and the single prerequisite. There is no filler or redundant information.

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 simple single-parameter removal tool with annotations covering destructiveness and idempotence, the description provides the core function and auth requirement. However, it could mention how to get the id (e.g., from cf_list_wishes) or what response to expect, and it lacks any elaboration on edge cases.

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% with a description for the 'id' parameter ('Wish entry UUID to remove'), so the description doesn't need to add parameter details. However, it also doesn't add any extra parameter context such as how to obtain the UUID or whether it accepts non-UUID identifiers.

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 uses the specific verb 'Remove' with the resource 'wishlist/bookmarks', clearly distinguishing it from sibling tools like cf_add_wish and cf_list_wishes. It also clarifies the scope as items rather than the whole list.

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 provides a prerequisite (authentication) but does not explicitly state when to use this tool versus alternatives like cf_add_wish or cf_list_wishes. The usage is implied from the verb and resource, but there are no explicit context or exclusion criteria.

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