remove-from-playlist

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

With no annotations, the description carries the full burden and discloses key behaviors: permanence ('Permanently'), cost ('50 quota units per item'), and the mandatory confirmation flag ('Requires confirm: true'). This goes beyond typical mutation descriptions, though it omits what happens on invalid IDs or if confirm is false.

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?

Three short sentences: the first front-loads the core purpose, the second and third add critical constraints. No filler or redundancy.

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?

The description covers purpose, cost, and confirmation for a simple 2-parameter tool with no output schema. It does not describe return values or error behavior, but the core operational context is sufficient for an agent to invoke it 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 coverage is 100%, so baseline is 3. The description adds semantic value by linking 'per item' cost to the array parameter and emphasizing that 'confirm: true' is required for the operation to execute, which is not fully explicit in the schema.

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 clearly states the action: 'Permanently remove specific items from a playlist by playlist-item ID' — a specific verb, resource, and mechanism. This clearly distinguishes from playlist creation, update, or clean operations among siblings.

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 verb 'remove' and the context 'from a playlist,' but no explicit when-to-use or alternatives are given (e.g., 'use clean-playlist for bulk removal'). The confirmation requirement is a prerequisite, not a usage guideline.

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