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

Annotations already declare readOnly and idempotent behavior. The description adds that this is a fully working router, that it falls back to nothing, and that no candidate is currently active, giving useful nuance beyond the annotations without contradiction.

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 somewhat repetitive with phrases like 'identical', 'same', and 'exactly', and the 'Falls back to nothing — this IS a full working router' section is slightly overwrought. It is still understandable but could be tighter.

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?

There is no output schema, but the description references ask_pipeworx for the same response shape and arguments, which provides sufficient context for an agent familiar with the sibling tool. The beta behavior and current state are also explained.

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 coverage is 100% with six alias parameters all pointing to the same natural-language question field. The description mentions 'same arguments as ask_pipeworx' but does not add meaningful detail 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 identifies this as the beta variant of ask_pipeworx, a universal router with the same tool set and response shape. It explicitly names the stable sibling and states the beta purpose: testing candidate routing improvements.

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 says to use it exactly like ask_pipeworx when wanting the newest routing, and explains that results are compared against the stable router. It does not explicitly state when to prefer ask_pipeworx over this beta, but the relationship is clear.

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