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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior. The description adds useful behavioral context: returns category-bucketed example questions, includes the exact tool and argument shape, is drawn from the live catalog, and supports optional topic narrowing. 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 front-loaded with natural-language query patterns and densely packs purpose, output, usage, and examples. However, it is one long run-on paragraph with a repetitive list of user phrasings that could be trimmed, keeping it just below a perfect score.

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?

Despite having no output schema, the description fully covers return content ('category-bucketed example questions... each with the exact tool + argument shape'), invocation behavior, and use case. It is complete for a simple tool with one optional parameter.

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 documents the optional topic parameter with values and 'omit for cross-category spread' guidance (100% coverage). The description adds examples like 'finance', 'pharma', 'betting' and says 'call with no arguments for full spread', but this largely restates the schema, so the baseline 3 applies.

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 uses a specific verb ('suggest') and resource ('questions'), and clearly positions the tool as the onboarding entry point for learning what Pipeworx can do. It distinguishes itself from sibling meta-tools by explaining that it teaches you how to call ask_pipeworx, entity_profile, and others.

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' and explains both no-argument and topic-filtered invocation. It does not explicitly name an alternative for users who already know what they want to ask, 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.
