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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false. The description adds value by disclosing the return structure (category-bucketed example questions with tool+argument shape) and the effect of omitting vs. passing the topic parameter. It does not contradict annotations and provides behavioral context beyond the structured metadata.

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 dense but every sentence earns its place. It front-loads with example user queries, then explains purpose, return value, parameter behavior, and usage priority. There is no filler or repetition; it is structured as a continuous, information-rich flow that remains easy to parse.

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?

For a one-optional-parameter tool with no output schema and rich annotations, the description is complete. It explains the return format, parameter semantics, and when to use the tool in the broader workflow. It also places the tool among siblings by referencing the meta-tools it helps learn, making it fully contextual for an agent.

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 input schema already describes the topic parameter with its allowed values and the meaning of omission ('Omit for a cross-category spread'), providing 100% coverage. The description repeats this with a few examples (finance, pharma, betting) but does not add significant new semantic meaning beyond what the schema already conveys. Baseline 3 is appropriate.

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 states a specific verb+resource+scope: it is the onboarding entry point for finding example questions and the exact tools that answer them. It lists example user queries, the return format (category-bucketed questions with tool+argument shape), and clearly distinguishes it from siblings by positioning it as the first tool to use when learning what Pipeworx can do.

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 explicit when-to-use guidance: '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 how to focus with the topic parameter. However, it does not explicitly say when not to use it versus alternatives like ask_pipeworx or discover_tools, so it lacks full when-not guidance.

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