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

Annotations already declare destructive=true, idempotent=true, and openWorld=true, so the safety profile is covered. The description still adds real value beyond them: non-member products are reported and ignored, an emptied list is not deleted, and removed products can be re-added.

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?

Four short sentences, front-loaded with the action and identity mechanism, followed by behavioral caveats. No sentence is filler; each carries a distinct fact.

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?

An output schema exists, so the return values need not be spelled out, yet the description still notes that remaining items are returned. Combined with the caveats about empty lists and re-adds, an agent has everything needed to call this mutation 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 100%, so the schema already documents edit_token, items, and market fully. The description only adds a light restatement that edit_token may be a full edit link or the trailing token, which the schema also covers. Baseline 3 is appropriate.

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 (Removes) and resource (products from a wishlist) plus the identity mechanism (edit link or trailing token). This is unambiguously distinguishable from siblings like add_to_wishlist, create_wishlist, and get_wishlist.

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 resource and by the paired add_to_wishlist sibling, but the description never states when to reach for this tool versus add_to_wishlist or get_wishlist, nor any prerequisite conditions. Adequate but leaves routing to inference.

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