create_plex_encrypt_apikey

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

Annotations indicate idempotentHint=true and destructiveHint=false, but the description adds no behavioral context beyond the endpoint. It does not explain what 'encrypt-apikey' does, whether it creates a new encrypted key, overwrites an existing one, or what side effects occur. With no annotations covering the operation's semantics, the description carries the burden and fails to disclose behavior.

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 it is under-specified rather than concise. It repeats the same information twice ('POST plex/encrypt-apikey' and 'POST /api/plex/encrypt-apikey') without adding any explanatory value.

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 tool with no parameters and an output schema, the description could be minimal, but it still fails to explain what the tool does, what the output represents, or how it relates to other Plex API key tools. An agent cannot determine the purpose or effect of calling this endpoint from the description alone.

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 tool has zero parameters, so there is no parameter semantics to document. The description's mention of the endpoint is the only relevant context, and with no parameters, the baseline of 4 is appropriate.

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 is essentially a tautology: it repeats the tool name and the HTTP endpoint ('POST plex/encrypt-apikey') without explaining what encrypting an API key means, what it does, or what the result is. It does not distinguish this from sibling tools like create_plex_apikey or create_plex_test_connection.

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. The description only restates the endpoint and provides no context about prerequisites, typical use cases, or when another Plex-related tool would be more appropriate.

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