Remove anime from my list

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

The description adds substantial behavioral context beyond annotations: deletion is irreversible, the API returns success even when the item was never on the list, and success is not proof of prior existence. This is valuable, non-obvious behavior that agents need to interpret the result correctly.

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?

Every sentence earns its place: the main action, irreversibility, the surprising success-response behavior, the advice to confirm via get_my_anime_list, and the auth requirement. It is dense but not bloated, and the most important semantics are front-loaded.

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 single-parameter mutation tool with an output schema and meaningful annotations, the description fully covers purpose, auth, destructive behavior, idempotency semantics, and a verification path. There is no meaningful missing context that would prevent an agent from using the tool 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?

The input schema already provides 100% coverage for anime_id, including its semantics, source, and naming caveat. The tool description itself adds no parameter-specific meaning, which is fine because the schema carries the full burden—exactly the baseline scenario.

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 a specific verb ('Remove') and a clear resource ('anime entry from the authenticated user's list'), and the title/name distinguishes it from sibling delete_my_manga_list_item. It immediately answers what the tool does and for whom.

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 clearly states the operation happens on the authenticated user's list, requires login, and advises checking get_my_anime_list when confirmation of prior existence is needed. It does not explicitly name delete_my_manga_list_item as the manga alternative, but the title and sibling context make that distinction obvious.

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