create_plex_test_connection

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

The description adds no behavioral context beyond the endpoint. Annotations already provide idempotentHint and destructiveHint, but the description does not explain what the test does, what happens on success/failure, or any 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 very concise, with the endpoint and parameter listed directly. It is not verbose, but the structure is minimal and lacks a clear statement of purpose. Still, it is efficient.

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 an output schema exists, the description does not state the tool's purpose or behavior. An agent cannot confidently determine when to use this tool or what it accomplishes beyond the endpoint. This is a significant gap.

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 description provides 'uri: Server URI', which clarifies the meaning of the sole parameter. This adds value beyond the schema, which only has type and title. The parameter is adequately explained.

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 the HTTP method and endpoint (POST /api/plex/test-connection) but does not explicitly say the tool tests a Plex server connection. It relies on the tool name for purpose, which is somewhat clear but not directly 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?

No guidance is given on when to use this tool versus alternatives like list_plex_test_connection or create_jellyfin_test_connection. The agent must infer usage from the name and endpoint, which is insufficient.

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