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

With no annotations, the description should disclose behavioral traits (e.g., whether it mutates state, triggers side effects). It only mentions cost and subscription, leaving the behavioral profile largely unknown.

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 extremely short, but it sacrifices necessary detail for brevity. It is not front-loaded with useful guidance; instead, it states basic facts that could be inferred from the name and annotations.

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?

Despite having an output schema, the tool lacks context on how input parameters affect behavior, making it incomplete for an AI agent to use correctly among many similar sibling tools.

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 description provides no information about the parameters (query, source_focus, conversation_id). Since schema description coverage is 0%, the entire burden is on the description, which it fails to meet.

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 names the model but does not specify the tool's function, such as performing a search or generating a response. It reads like a label rather than a functional description, making it unclear what the tool actually does.

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 description mentions subscription and cost requirements but provides no guidance on when to use this tool over siblings like pplx_sonar or pplx_ask. No context on appropriate scenarios or exclusions is given.

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