create_webhooks_plex

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

Annotations already indicate idempotency, non-read-only, and non-destructive behavior. The description adds the event trigger and HTTP method, but does not disclose side effects, authentication needs, or expected caller. This is adequate but not rich, given the annotations already carry part of the burden.

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 compact and front-loaded: the purpose is in the first sentence, followed by the endpoint and argument summary. There is no filler or redundant prose.

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 though there is an output schema and useful annotations, the description omits critical context: who sends this webhook, what a valid payload looks like, and how this relates to Plex webhook setup tools. An agent cannot confidently construct the exact 'payload' string needed to trigger the intended search.

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%, so the description must compensate. It only says 'payload: Webhook payload', which barely restates the schema's 'Payload' title. No format, JSON structure, or example of the expected Plex payload is provided, leaving the single required parameter underspecified.

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 action ('Trigger subtitles search') and the triggering condition ('play media event in Plex'), plus the endpoint. This clearly distinguishes it from sibling tools like create_plex_webhook_create or create_webhooks_radarr, which manage different webhook behaviors.

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 invoke this tool versus alternatives such as create_plex_webhook_create. It is only implied that it responds to a Plex play media event, but there is no explicit statement about prerequisites, callers, or how it differs from sibling webhook tools.

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