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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds behavioral context beyond these: it returns category-bucketed example questions, includes exact tool+argument shapes, and mentions that the examples are drawn from a live catalog. This provides significant additional transparency without contradicting 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 concise, consisting of approximately 4 sentences. It front-loads common aliases and the core purpose. While it includes a detailed list of categories (company financials, drugs, etc.) that partially repeats the schema's enum examples, it remains efficient and well structured.

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's low complexity (1 optional parameter, no output schema), the description is complete. It explains what the tool returns, how to use it (with/without topic), and when to use it (first-time onboarding). The return value description (category buckets with tool examples) is sufficient without an output schema.

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 coverage is 100% (only one parameter, 'topic'). The description adds value by listing the possible topics (finance, pharma, etc.) and explaining that omitting the parameter gives a cross-category spread. This supplements the schema's description, earning a score above baseline 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 that this is the onboarding entry point for an agent wanting to know what questions to ask Pipeworx. It specifies the return value (category-bucketed example questions with tool/argument shapes) and distinguishes itself from siblings by being the first tool to use when ignorant of Pipeworx capabilities.

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 says '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 clear guidance on when to use it. It does not explicitly mention when not to use it, but the positive guidance is strong, and context with 'first' implies alternatives exist for other situations.

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