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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive, so safety is covered. The description adds meaningful behavioral context beyond annotations: it states the output is 'category-bucketed example questions... drawn from the live catalog of thousands of tools', which sets expectations about freshness and content. No contradictions.

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 on the longer side, but every part earns its place: usage examples, core purpose, output details, and invocation guidance. It is front-loaded with natural language queries that quickly orient the reader. A slight miss on perfect conciseness due to the lengthy example list, but overall well structured.

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 tool with one optional parameter, no output schema, and strong annotations, the description covers all necessary context: when to use it, what it returns, how to customize, and relationship to meta-tools. The openWorldHint and non-destructive annotations further complete the picture. Nothing critical is missing.

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 100%, as the schema already documents the 'topic' parameter's allowed values and the 'omit for cross-category' behavior. The description reinforces this with examples like 'finance', 'pharma', 'betting' but adds no new semantic info beyond the schema. 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 clearly states this is 'the onboarding entry point' that returns 'category-bucketed example questions' with exact tool+argument shapes. It uses specific verbs like 'suggest' and 'returns', and distinguishes itself from sibling tools by positioning itself as the first thing to use when unfamiliar with Pipeworx. This is a precise, non-tautological purpose.

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?

Explicitly instructs when to use it: 'Use this FIRST when you do not yet know what Pipeworx can do for you.' It also explains parameter usage ('Call with no arguments for the full spread, or pass topic to focus') and hints at alternatives by listing meta-tools to learn about. Clear contextual guidance.

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