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

No annotations exist. The description notes 'COSTS 1 PRO SEARCH QUERY', which is a useful behavioral detail about cost, but fails to disclose mutation, side effects, response characteristics, or safety.

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 very short but under-specified. It omits critical information, making it not concise in a useful sense.

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 2 parameters, no schema descriptions, and an output schema without return details, the description is wholly inadequate for an agent to invoke the tool 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?

Schema description coverage is 0% and the description provides no explanation of the two parameters (query, source_focus). An agent cannot infer parameter meaning or usage.

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 identifies the model as 'GPT-5.4 — OpenAI's versatile model' but lacks an action verb (e.g., query, generate). It does not specify what the tool does, making it vague compared to siblings like 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 on when to use this tool versus alternatives such as pplx_gpt55 or pplx_gpt54_thinking. No mention of context or exclusion criteria.

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