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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds behavioral context about what the tool returns (category-bucketed examples with tool+argument shape) and that it draws from the live catalog, going beyond annotations without contradicting them.

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 a single dense paragraph but every sentence provides value: purpose, return shape, parameter behavior, and usage timing. It could be improved with bullet points or shorter sentences, but it is not wasteful.

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 what the tool returns (category-bucketed example questions with exact tool+argument shape) and covers both invocation modes. Given the tool's simple API (one optional parameter), the description is complete with no critical gaps.

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 coverage is 100% for the single optional `topic` parameter, but the description adds meaningful usage nuance: calling with no arguments gives the full spread, and passing a topic (with examples like 'finance', 'pharma', 'betting') focuses results. This enriches the schema's terse list of categories.

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 identifies the tool as an onboarding entry point that suggests example questions with exact tool and argument shapes. It distinguishes from siblings by emphasizing its role as a meta-orientation tool ('Use this FIRST'), and the title 'What Can I Ask Pipeworx?' reinforces the specific 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 states when to use it: '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 alternative of passing a `topic` for focus versus omitting it for a full spread, giving clear actionable guidance.

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