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

The only behavioral trait disclosed is cost ('COSTS 1 PRO SEARCH QUERY'). No annotations exist to supplement, so the description falls short on rate limits, auth needs, or operational details.

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 concise (two sentences) but lacks substantive content. It earns no penalties for verbosity, but brevity here comes at the cost of clarity.

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?

Given the tool has 3 parameters, an output schema, and many siblings, the description is severely incomplete. It omits the tool's purpose, parameter details, and any usage context.

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?

Schema coverage is 0% (no parameter descriptions) and the description adds no meaning to the three parameters (query, source_focus, conversation_id). The agent learns nothing about argument expectations.

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 identifies the model as 'Grok 4.5 — xAI's most advanced model' and mentions cost, but does not state the tool's action or operation (e.g., query, generate). It fails to differentiate from sibling tools like pplx_grok45_thinking or pplx_query.

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?

No guidance is provided on when to use this tool versus alternatives. With many similar sibling tools, the agent receives no help in selecting this tool.

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