create_plex_webhook_create

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

The description is entirely silent on behavior—no mention of what the operation does, what side effects exist, what is created, or what the response contains. Annotations only indicate idempotentHint=true, but the description adds no context beyond that. The agent has no insight into expected outcomes or potential side effects.

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 extremely short but redundant—it repeats the same endpoint in two different formats. This is under-specification, not conciseness. The repetitive lines do not earn their place, and the description would be more concise if it simply stated the purpose in one sentence.

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?

Even for a simple tool with no parameters and an output schema, the description fails to state what the tool does. An agent cannot infer that this creates a Plex webhook, what the expected outcome is, or how it relates to other webhook operations. The description is fundamentally incomplete.

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?

With zero parameters in the schema (100% coverage), the description does not need to explain parameter semantics. The baseline for 0 params is 4, and since there are no parameters to clarify, the description adequately (if minimally) meets this requirement by not adding contradictory or misleading information.

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 only repeats the endpoint path ('POST plex/webhook/create' and 'POST /api/plex/webhook/create'), which is essentially a tautology of the tool name. It does not state what the tool actually does (e.g., creating a Plex webhook configuration), nor does it distinguish it from siblings like create_plex_webhook_delete or list_plex_webhook_list.

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?

No guidance is provided on when to use this tool versus alternatives. There are many related Plex webhook and other create tools among the siblings, but the description gives no context about the purpose, prerequisites, or selection criteria.

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