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

Annotations already establish safety (readOnlyHint, idempotentHint, non-destructive), and the description goes well beyond that by disclosing output structure (category-bucketed questions with tool+argument shape), dynamic source ('drawn from the live catalog of thousands of tools'), and invocation behavior (no-arg vs topic). 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 dense but well-organized: it front-loads common queries and the core purpose, then covers output content, invocation variants, and when to use the tool. Every sentence contributes—no filler or 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?

Even though there is no output schema, the description adequately explains what the tool returns: category-bucketed example questions with tool+argument shapes, plus a list of categories. It lacks explicit error handling or invalid-topic behavior, but for a simple onboarding tool the description is substantially complete.

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 already documents the `topic` parameter with allowed values and 'Omit for a cross-category spread.' The description adds concrete examples ('finance', 'pharma', 'betting') and reinforces the semantics of 'full spread' versus focused topics, which slightly exceeds the schema's bare enum list.

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 explicitly states this is the 'onboarding entry point' and 'returns category-bucketed example questions' with 'the exact tool + argument shape' for each. It clearly distinguishes itself from siblings by saying 'Use this FIRST when you do not yet know what Pipeworx can do.'

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 gives explicit when-to-use 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 two invocation styles—'Call with no arguments for the full spread, or pass `topic`.' However, it does not explicitly say when NOT to use it or name an alternative tool, so it lacks full exclusionary guidance.

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