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

Annotations already declare readOnly/openWorld/idempotent/non-destructive behavior, and the description adds concrete behavioral context: it returns category-bucketed examples, includes exact tool+argument shape, and supports optional topic narrowing. There is no annotation contradiction, and the extra detail about output structure and parameter effect is valuable beyond the safety hints.

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 and front-loaded with user-question examples, then explains output, parameters, and usage in one flowing paragraph. Every clause serves a purpose, though it is somewhat long and could be tightened, so it earns a 4 rather than a 5.

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 simple tool with one optional parameter and no output schema, the description covers what it returns, how to invoke it, and when to use it, even naming the meta-tools users can learn next. It fully addresses the onboarding use case with no missing operational detail.

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 single optional `topic` parameter with valid values and the omit-for-cross-category behavior, providing 100% coverage. The description adds only mild reinforcement with examples like 'finance', 'pharma', 'betting' and the phrase 'to focus', which does not significantly go 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 is the onboarding entry point for discovering what Pipeworx can do, listing natural-language trigger phrases and specifying that it returns category-bucketed example questions with exact tool and argument shapes. This distinguishes it from general ask/entity tools by positioning it as the first-stop discovery tool.

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?

It 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', which is clear when-to-use guidance. However, it doesn't name alternative discovery tools like discover_tools or state explicit when-not-to-use conditions, so it stops short of full alternative/exclusion coverage.

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