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

The annotations already declare readOnly, openWorld, idempotent, and non-destructive hints. The description adds valuable context beyond the annotations: the response format (category-bucketed example questions), that the catalog is live and large, and the behavior of omitting vs. passing topic. It does not contradict the annotations and enriches the agent's understanding of side-effect-free, open-ended querying.

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 and front-loaded with user phrasings, then explains the response, usage, and priority. Every sentence contributes information, but the opening list of paraphrases is somewhat verbose and could be condensed. Overall it is efficient for the complexity it covers.

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 is thorough: it explains what the tool returns (category-bucketed examples with tool shapes), how to call it (with/without topic), and when to use it. The annotations cover safety, so no behavioral gaps remain. The description fully compensates for the lack of 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 description covers 100% of the parameter meaning: the 'topic' field lists valid focus areas and says omitting gives a cross-category spread. The tool description repeats 'call with no arguments for the full spread, or pass topic' and gives examples, but adds no new information beyond the schema. This matches the baseline for high schema coverage.

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 is highly specific: it names the exact entry-point verb ('onboarding entry point') and resource (Pipeworx capabilities). It clearly differentiates from siblings by stating it returns category-bucketed example questions with tool+argument shapes, and explicitly positions it as the tool to use before knowing what to ask. The listed user phrasings also make intent unmistakable.

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') and mentions alternatives (meta-tools like ask_pipeworx, entity_profile). However, it does not explicitly state when NOT to use it or compare against similar tools like discover_tools, so it falls just short of a 5.

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