create_users_settings_plex_connect

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

Annotations already mark this as non-read-only, idempotent, non-destructive, and open-world. The description adds no behavioral context beyond the endpoint and payload note; it does not explain side effects of connecting Plex, required auth state, or what changes on the server. There is no contradiction with annotations.

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 definition is compact and front-loaded: 'Connect Plex.' immediately states the action, the endpoint line anchors the call, and the body guidance is short. Every sentence earns its place without 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?

For a one-parameter open-world POST, the description gives the bare minimum: endpoint and a body discovery pointer. It omits when to choose this over create_users_settings_plex_sync, what connecting actually does, and any preconditions; the presence of an output schema covers return shape but not these operational gaps.

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 only parameter, body, is an open object with no schema-level field documentation (0% coverage). The description usefully directs the agent to consult the matching GET or /schema endpoint to discover expected fields, which partially compensates for the missing schema. It still does not name or explain any actual body fields.

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 opens with 'Connect Plex.' and gives the exact POST endpoint, clearly naming a specific action and resource. It does not explicitly contrast itself with the similar create_users_settings_plex_sync or update_users_settings_plex tools, so sibling differentiation is implicit rather than stated.

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?

There is no guidance on when to use this tool versus the many related Plex settings/sync tools. The only guidance is to read the matching GET or /schema endpoint before constructing the body, which helps with invocation but not with tool selection.

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