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

Annotations already declare safe read-only, idempotent behavior, so the burden is lower. The description adds useful behavioral detail: results are 'drawn from the live catalog of thousands of tools,' it returns category-bucketed examples, and behavior changes based on the optional topic parameter. This goes beyond what annotations alone convey, though it does not describe internal side effects or performance characteristics, which are not critical here.

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 long but front-loaded with natural-language example prompts, then quickly explains purpose, return content, parameter usage, and when to use. It is somewhat dense with category lists, but every part earns its place by teaching the agent how to interact with the meta-tools and what to expect. The structure moves from user intent to tool behavior to invocation details efficiently.

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 single-optional-parameter tool with no output schema, the description is remarkably complete: it states purpose, return format (category-bucketed examples with tool + argument shape), input behavior, and when to prefer this tool. Without a formal output schema, the description adequately covers return values. It also contextualizes this tool among sibling tools, satisfying the need for contextual completeness.

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 describes the single optional parameter with 100% coverage, listing valid topic values and the default behavior. The description enriches this by giving concrete examples ('finance', 'pharma', 'betting'), explaining that omitting the topic yields a cross-category spread, and clarifying how the parameter focuses the returned suggestions. This adds meaningful guidance beyond 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 clearly identifies suggest_questions as the onboarding entry point for learning what Pipeworx can do, returning category-bucketed example questions with the exact tool and argument shape. It distinguishes itself from siblings like discover_tools and ask_pipeworx by framing its specific role: showing what to ask and how to call meta-tools.

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?

Provides explicit guidance: '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 when to call with no arguments versus passing a topic, and names related meta-tools such as ask_pipeworx, entity_profile, and compare_entities, giving clear context for when this tool is appropriate.

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