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

The description discloses all behavioral traits: it is a read-only, idempotent operation (consistent with annotations) that returns category-bucketed example questions with tool shapes. It adds context about drawing from a live catalog and the ability to call with no args or a topic. No contradictions 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 example queries and is efficiently structured, but it is a single dense paragraph. While every sentence adds value, it could be slightly more concise by breaking into bullet points or shorter sentences. Overall, it is well-organized with no redundancy.

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?

Given the tool is simple (one optional parameter, no output schema), the description covers purpose, usage examples, relationship to siblings, and what the return contains ('category-bucketed example questions'). It fully compensates for the lack of an output schema with clear behavioral context.

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% (one parameter 'topic' with description). The description adds value by listing example values ('finance', 'pharma', etc.) and explaining the behavior of omitting the parameter ('Omit for a cross-category spread'). This goes beyond the schema definition, justifying a score above the baseline of 3.

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 it is the onboarding entry point, returning example questions with tool calls to learn what Pipeworx can do. It explicitly distinguishes from sibling tools like ask_pipeworx, entity_profile, and compare_entities, stating 'Use this FIRST when you do not yet know what Pipeworx can do for you, or to learn how to call the meta-tools.' This provides specific verb+resource and differentiates from alternatives.

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 specifies when to use the tool (when unsure what Pipeworx can do, or to learn meta-tools) and lists example user queries ('What can I ask Pipeworx?', 'give me ideas', etc.). It implies alternatives by referencing the meta-tools themselves, but does not explicitly state when not to use it (e.g., when already knowing what to ask). This is clear but has a minor gap in exclusion guidance.

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