seerr_create_user

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

The description says 'WRITE: this modifies your Seerr instance,' but this largely duplicates the existing annotation readOnlyHint=false. It does not disclose authentication requirements, specific side effects, failure modes, or whether the operation is reversible. The annotations already signal non-read-only behavior, so the description adds minimal behavioral context.

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, concise sentence that front-loads the core purpose ('Create new user'). The 'WRITE' clause is slightly redundant given annotations, but it is brief and does not bloat the description. It is efficiently structured for quick scanning.

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 that creates a user via an opaque request body, the description is severely incomplete. It gives no guidance on required or optional fields, no mention of what the output response contains (though an output schema exists), and no warning about potential consequences beyond a generic 'modifies.' Without additional parameter context, the agent cannot reliably invoke this tool.

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 input schema has a single 'body' object with additionalProperties=true and no field descriptions, and schema description coverage is 0%. The description does not mention any parameters or explain what the body should contain (e.g., username, password, email). The agent has no way to construct the request body correctly.

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 ('Create new user') and the resource ('user'), making the tool's purpose immediately obvious. The added 'WRITE: this modifies your Seerr instance' reinforces that this is a mutating operation. It is distinct enough from sibling tools like seerr_update_user or seerr_import_plex_users, though no explicit sibling differentiation is provided.

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 usage is implied by the verb 'Create new user' – the agent can infer it should be used to add a user to Seerr. However, there is no explicit guidance about when to use this versus alternatives like seerr_import_plex_users, nor any mention of prerequisites or exclusions. This is adequate implied usage but lacks explicit context.

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