create_settings_plex

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

Annotations already convey idempotency and non-destructiveness, and the description adds the requirement to consult GET/schema first. It does not describe effects such as merging/replacing fields or auth expectations, but annotations lower 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?

Three short sentences: action, endpoint, and parameter guidance. There is no redundant or misleading 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?

For an open-body settings update with an output schema and annotations, the description covers the key requirements: endpoint, mutation intent, and how to discover body fields. It could be more explicit about naming the sibling GET tool, but it is not 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?

The body schema is an open object with 0% coverage, so the description's instruction to read the matching GET or /schema endpoint is essential for discovering valid fields. It compensates for the empty schema, though it leaves actual field discovery to another call.

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 'Update Plex settings,' identifying a specific verb and resource. It is clear, but it does not explicitly differentiate from sibling tools like list_settings_plex or create_settings_plex_sync.

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?

It states the operation (update Plex settings) and instructs the agent to read the matching GET or /schema endpoint before calling. This is clear context for when to use it, though it does not name alternatives or exclusions.

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