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

Annotations already convey read-only, non-destructive, open-world behavior; the description adds useful context by revealing that the tool routes to 5,743 tools, fills arguments automatically, and returns structured answers with stable pipeworx:// citation URIs. It does not contradict the annotations and provides behavior beyond what the structured fields state.

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 opening is front-loaded and effective, but the description becomes redundant: it repeats the 'START HERE' guidance and duplicates the entire example list near the end. This bloats the description and makes it less concise without adding new information.

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 tool with one required question parameter, the description is largely complete: it explains when to use the tool, what it does, how it returns results, and provides representative examples. The main gap is not addressing how the sibling variants (ask_pipeworx_beta, ask_pipeworx_grounded) differ from this one.

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 description coverage is 100%, with all six parameters documented as aliases for a natural-language question. The description adds example queries and reinforces that the input should be a user-style question, but it does not add meaningful parameter-level semantics beyond what the schema already provides.

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 identifies ask_pipeworx as a router that answers factual questions using authoritative, cited data and explicitly says to prefer it over web search. It enumerates many domains and gives concrete examples, making the tool's purpose scannable. However, it does not distinguish this tool from its siblings ask_pipeworx_beta and ask_pipeworx_grounded.

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 provides strong when-to-use guidance: it names web search as the alternative, lists trigger phrases like 'what is', 'look up', and 'get the latest', and tells the agent to 'START HERE for most questions'. It does not explain when to choose ask_pipeworx_beta or ask_pipeworx_grounded instead, so it stops short of a full 5.

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