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

The description discloses live experimental routing changes, the current inactive candidate state with a retirement date, that it does not fall back to a separate stable path, and that it is a fully working router. This adds meaningful operational context beyond the annotations' read-only, idempotent, and open-world 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 tightly written and front-loads the core identity: beta universal router identical to ask_pipeworx. Each sentence adds value: current candidate status, usage instruction, comparison purpose, and the no-fallback clarification, with no filler.

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 six-alias string-parameter schema with strong annotations, the description covers identity, invocation, current state, and experimental risk. It relies on ask_pipeworx for exact response-shape details, but in the sibling context that is sufficient for correct selection and invocation.

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%: all six parameters have descriptions, mostly aliases for the natural-language question. The description only says 'same arguments' and does not add parameter-level detail, but the schema already carries that burden, so baseline 3 is appropriate.

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 this as a beta universal router with the same 5,738 tools, arguments, and response shape as ask_pipeworx, so an agent can tell what it does. It distinguishes it from the stable ask_pipeworx by emphasizing the experimental routing edge, though it relies somewhat on the sibling name rather than stating an independent core purpose.

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 the newest routing is desired and explains that results are compared against the stable router. It names the stable alternative and the condition for choosing this variant, though it does not explicitly state when-not to use it or advise preferring the stable router for production.

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