Remove Saved Albums

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

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is largely covered. The description adds one useful operational detail — the batch limit of 20 — but does not say whether removals are reversible or what happens when an ID is not currently saved.

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 opening sentence is front-loaded and precise, with the batch limit placed right next to the parameter. The literal "Args:" wrapper is docstring boilerplate rather than prose, but it costs little space.

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 return values need not be explained, and the batch semantics are covered. However, for a destructive library mutation the description omits authorization scope and partial-failure behavior (e.g., invalid or unsaved IDs), which an agent would want before invoking.

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 the schema only types the field as an array of strings, so the description carries real weight by clarifying that entries may be album IDs or URIs and that at most 20 may be supplied. That is meaningful semantics the schema alone does not convey.

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 states a specific verb and resource ("Remove albums from the user's library"), which cleanly separates it from save_albums and check_saved_albums. It does not explicitly name the sibling alternatives, but the action and target are unambiguous.

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 explicit when-to-use or when-not-to-use guidance, and no mention of prerequisites such as the user authorization scope required to modify a library. An agent must infer usage purely from the tool name and the phrase "from the user's library".

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