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

The description adds meaningful behavioral context beyond the annotations: it is a live experimental router, no candidate is active right now, so it currently matches ask_pipeworx exactly, and it does not fall back because it is a full working router. This complements the readOnly, openWorld, and idempotent annotations without contradicting them.

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?

Four sentences, front-loaded with the beta identity and key parity statement. Every sentence contributes useful context about current behavior, usage, and experimental status, though it is slightly dense.

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?

The description covers purpose, current parity with ask_pipeworx, usage condition, and experimental nature, with safety profile supplied by annotations. It lacks an explicit example or detailed return format, but the statement that the response shape matches ask_pipeworx mitigates that gap.

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 the required question parameter and its five aliases fully documented. The description adds no parameter-specific meaning, but none is needed given the schema's completeness.

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 identifies the tool as a beta version of ask_pipeworx and a universal router with the same 5,724 tools, arguments, and response shape. This clearly distinguishes it from the stable sibling ask_pipeworx and makes its scope concrete.

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 to use it exactly like ask_pipeworx when you want the newest routing, and explains that results are compared against the stable router to decide merges. It does not explicitly state when to prefer the stable ask_pipeworx, but the experimental-edge framing makes that choice reasonably clear.

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