pplx_auth_complete

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

No annotations provided. Description discloses successful outcome (session token saved, tools work) and return of status/subscription tier, but does not cover failure behavior or safety traits beyond what is implied.

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?

Four sentences plus structured Args/Returns sections. No wasted words, front-loaded with core purpose, and easy to parse.

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?

Adequately covers the authentication completion step given output schema exists and sibling tools are many. Parameter semantics are clear, though schema coverage is low.

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?

Adds meaning beyond schema: email identified as 'same as used in pplx_auth_request_code', code described as '6-digit verification code from your email'. Schema coverage is 0%, so description compensates well.

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?

Description uses specific verb 'Complete' and resource 'Perplexity authentication', distinguishing it from sibling tools like pplx_auth_request_code (requesting code) and pplx_auth_status (checking status).

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?

Explicitly states to use after pplx_auth_request_code and that success enables all pplx_* tools. Lacks explicit when-not-to-use or alternatives, but context is clear.

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