seerr_login_plex

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

The description explicitly states 'WRITE: this modifies your Seerr instance,' which adds a behavioral warning beyond the annotations. However, it does not specify the exact side effects, prerequisites, or reversibility, leaving the mutation scope vague.

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 a single, front-loaded sentence that immediately conveys the core action and side effect. Every word contributes value, with no filler or unnecessary detail.

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?

The tool is a simple login action, but the parameter schema offers no guidance and the description does not explain how to supply the Plex token. The presence of an output schema helps, but the lack of parameter semantics and usage context leaves the tool incomplete for an agent to invoke it correctly.

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 schema has one parameter 'body' with no description and additionalProperties true, providing zero documentation. The description mentions 'Plex token' but fails to explain how it should be structured within the body, making correct invocation very difficult.

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 clearly states the action ('Sign in using a Plex token') and the resource (your Seerr instance). It effectively distinguishes from sibling auth tools like seerr_login_jellyfin and seerr_login_local by specifying the Plex token mechanism.

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?

The intended use is implied by the name and description: use this when you have a Plex token to authenticate. However, it does not explicitly mention when not to use it or other alternatives such as seerr_login_jellyfin or seerr_login_local, leaving some ambiguity about selection.

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