remove_from_playlist

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

Annotations already set readOnlyHint=false, destructiveHint=false, and openWorldHint=true. The description adds valuable context by noting the mutative ops flag requirement, which is not present in the annotations. It does not elaborate on side effects or return values, but given the annotation coverage, this is more than adequate.

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 a single sentence, front-loaded with the action and requirement. Every word earns its place; there is no fluff or repetition.

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 2-parameter mutation tool with no output schema, the description covers the critical prerequisite (mutative ops flag) and the core action. It doesn't explain error behavior or return format, but these are not essential given the simplicity and the presence of sibling tools for context.

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%, with clear descriptions for both playlistId and playlistItemId. The tool description adds no additional parameter semantics beyond schema, so the baseline of 3 applies—the schema does the heavy lifting.

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 resource 'item from a playlist', clearly distinguishing from siblings like add_to_playlist, clear_playlist, and delete_playlist. It also includes an essential prerequisite (PLEX_ENABLE_MUTATIVE_OPS=true) that adds operational clarity.

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 explicitly states the requirement for PLEX_ENABLE_MUTATIVE_OPS=true, which is a key condition for using this tool. It implies use when removing a single item from a playlist, but does not explicitly name alternatives like clear_playlist for bulk removal or delete_playlist for whole-playlist deletion, though sibling names signal these distinctions.

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