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

Annotations declare readOnlyHint=false and destructiveHint=false, and the description does not contradict these. The description adds the return format and examples, but does not elaborate on side effects, permissions, or specifics of destructive operations like delete. For a multi-operation tool, more behavioral context would be helpful.

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 structured with a rationale, return format, and examples. While the portmanteau rationale adds context, the text is slightly verbose but each section provides useful information.

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 tool is complex with 7 operations, and the description provides a clear return format and representative examples. However, it does not detail the behavior of each operation or edge cases, relying heavily on the schema's enum definitions.

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% description coverage for all parameters. The description enhances understanding by showing examples such as operation='list' and operation='create' with title and library_id, demonstrating how parameters are used together.

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 identifies the tool as a collections management tool for Plex, consolidating 7 operations (list, get, create, update, delete, add_items, remove_items). This distinguishes it from siblings by focusing specifically on collections rather than playlists or general library management.

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 explains the portmanteau rationale and provides examples, but does not explicitly state when to use this tool over other Plex tools. It implies usage for collection-related tasks but lacks exclusionary guidance or alternative recommendations.

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