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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, destructiveHint=false, so safety is clear. The description adds value by explaining the tool returns category-bucketed example questions drawn from the live catalog and that it can be called with no arguments or a topic. It could mention potential caching or freshness, but overall it's transparent.

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 well-structured: alternative phrasings, purpose, output explanation, calling instructions, and usage guidance. Every sentence adds value without redundancy. It is front-loaded with the core idea and remains concise.

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 no output schema, the description adequately describes the output (category-bucketed example questions with tool+argument shapes). It mentions the source (live catalog of thousands of tools) and how to adjust focus. This is complete for a discovery tool with minimal state.

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 clear description of the single optional parameter `topic`. The tool description elaborates by listing specific focus areas (finance, pharma, etc.) and explaining that omitting the topic gives a cross-category spread, adding meaning 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 states the tool returns category-bucketed example questions with tool+argument shapes, serving as an onboarding entry point. It explicitly distinguishes from siblings like ask_pipeworx by noting 'Use this FIRST when you do not yet know what Pipeworx can do for you' and listing meta-tools to learn.

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 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 implies alternative tools for specific queries (e.g., ask_pipeworx) without explicitly listing exclusions, but the context signals show many siblings, and the description effectively differentiates.

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