Instructions

Input Schema

No arguments

Behavior3/5

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

No annotations provided, so description carries full burden. It discloses that the tool initiates OAuth and returns a login URL, which is adequate for a simple 0-param tool. However, lacks details about side effects (e.g., session creation) or expected behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, 10 words, directly conveys purpose without filler. Highly concise and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool is simple (no params, no output schema). Description covers what it does and what it returns. Could hint at next steps (e.g., 'user must open URL in browser') but not strictly necessary given sibling tools like check_auth_status.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters in schema; baseline is 4 per guidelines. Description adds no parameter details, but none are needed. Schema coverage is 100% so no gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description uses specific verb 'Initiate' and resource 'Plex OAuth authentication flow', clearly stating the outcome 'get user login URL'. It effectively distinguishes from sibling tools like check_auth_status and clear_auth by focusing on the initiation step.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives (e.g., check_auth_status or clear_auth). Missing context like prerequisites or when not to call it.

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