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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior, which covers the safety profile. The description adds valuable context beyond annotations by explaining the tool returns category-bucketed examples derived from the live catalog, includes exact tool and argument shapes, and requires no arguments for a full spread. There is no contradiction with annotations.

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 longer than average but every component serves a purpose: common user phrasings, the return format, the tool's role, parameter usage, and when to call it first. The natural language examples at the start and the explicit 'Use this FIRST' directive are front-loaded and impactful. Slight redundancy in listing example topics that appear again in the schema prevents a 5.

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 and no output schema, the description fully covers what the tool returns, how to invoke it, how to scope it, and when to use it. It even names the meta-tools it teaches, so an agent would have no difficulty calling it correctly or interpreting its purpose.

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 documents the single optional topic parameter with a complete description and examples, so baseline is 3. The description adds semantic nuance by framing the parameter as 'focus' with domain examples and clarifying that omitting it yields a cross-category spread. This meaningfully enriches the schema definition.

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 precisely identifies the tool as the onboarding entry point for a newly connected agent, explaining it returns category-bucketed example questions across domains and the exact tool and argument shape to answer them. It clearly distinguishes itself from sibling tools like discover_tools by focusing on 'what can I ask' rather than generic discovery, and even names specific meta-tools it teaches.

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 explicitly states 'Use this FIRST when you do not yet know what Pipeworx can do for you,' giving a clear condition for when to invoke it. It also explains how to narrow the scope via an optional topic, but it does not explicitly name sibling alternatives or when to choose them, so it falls just 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.
