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

Annotations already declare read-only, open-world, idempotent, and non-destructive behavior. The description adds meaningful behavioral context beyond this: returns category-bucketed example questions, draws from a live catalog, includes tool+argument shape per example, and supports both full-spread and topic-focused modes. No contradictions exist.

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 effective and information-dense after the opening em-dash list, but the list of seven synonymous questions ('What can I ask Pipeworx? / what is Pipeworx good for? / ...') is redundant and adds little beyond pattern matching. Trimming that would make the description more concise while preserving its clarity.

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 everything needed: what it returns (category-bucketed example questions with tool+argument shapes), how to invoke it (no args vs topic), when to use it ('FIRST'), and even which meta-tools it teaches. No gaps are apparent.

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% with a well-described 'topic' parameter, so the baseline is 3. The description adds value by providing concrete example values ('finance', 'pharma', 'betting') and the semantic meaning of omitting the parameter (cross-category spread), which enriches the schema.

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 questions') and identifies a clear resource: an onboarding entry point that returns category-bucketed example questions with tool+argument shapes. It strongly distinguishes itself from siblings like ask_pipeworx (which answers questions) and discover_tools (which likely lists tools) by centering on what to ask and how to ask it.

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 when to use: 'Use this FIRST when you do not yet know what Pipeworx can do for you' and to learn how to call meta-tools. It also explains the optional topic parameter for focusing. However, it does not explicitly mention when NOT to use it or name alternative tools for other scenarios, so it falls 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.
