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

The description provides a behavioral note on cost ('COSTS 1 PRO SEARCH QUERY') but no other disclosures (e.g., rate limits, output format, data handling). With no annotations, more context is expected.

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 (two sentences) and front-loaded with the model name and cost. Every word serves a purpose, but the brevity sacrifices comprehensiveness.

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 description omits crucial details about parameter usage, return values, and how this tool differs from many similar siblings. It is insufficient for correct invocation.

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 does not explain any of the three parameters (query, source_focus, conversation_id). The agent has no additional meaning beyond the schema names.

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 tool as an advanced model (Kimi K2.6) but lacks a verb indicating the action (e.g., query, ask). It vaguely implies a query function via the sibling tools context, but does not explicitly state what the tool 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?

No guidance on when to use this tool versus alternatives like pplx_query or pplx_ask. The description merely mentions the model name and cost without clarifying the use case or exclusions.

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