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

Beyond the annotations (readOnly, openWorld, idempotent, non-destructive), the description adds rich behavioral context: it returns category-bucketed questions, each with the exact tool and argument shape, and is drawn from a live catalog of thousands of tools. This conveys that the output is dynamic and is a meta-tool, which is valuable for an agent selecting and invoking it.

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 front-loaded with natural language example queries, then states the core purpose, output format, and usage options. Every sentence contributes value: the introductory queries capture intent, the body explains the tool, and the closing sentence provides explicit usage guidance. No unnecessary filler.

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?

With no output schema, the description fully explains the return value (category-bucketed questions with exact tool call shapes). It also covers use cases, the optional parameter behavior, and how to start. Given the tool's complexity as an onboarding/meta-tool, the description is complete enough for an agent to know what it does and when to call it.

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 schema already provides 100% coverage for the `topic` parameter with a value list and description. The description adds extra meaning by explaining the behavior of omitting the parameter ('Call with no arguments for the full spread') and giving example topics ('finance', 'pharma', 'betting') beyond the schema's enum list. This goes beyond the baseline.

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 clearly states a specific purpose: it is the onboarding entry point that returns category-bucketed example questions with the exact tool and argument shape to answer each. It distinguishes itself from sibling tools by framing itself as the first tool to use ('Use this FIRST') and by explicitly mentioning that it teaches how to call meta-tools like ask_pipeworx and compare_entities.

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 gives an explicit when-to-use: 'Use this FIRST when you do not yet know what Pipeworx can do for you, or to learn how to call the meta-tools.' It also explains the optional topic parameter to focus results. However, it does not explicitly name alternative tools or state when not to use it, so it stops short of a 5.

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