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

The description adds substantial behavior beyond the readOnly/idempotent/openWorld annotations: it discloses that candidate routing improvements may be live under test, that no candidate is currently active, that it is a full working router with no fallback, and that results are compared against the stable router. This is exactly the kind of experimental-risk transparency an agent needs.

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 front-loaded and information-dense, but it repeats the 'identical/exactly like ask_pipeworx' point three times. Each sentence adds some value, though tightening the redundancy would improve clarity.

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 beta router with no output schema, the description covers what the tool does, its current state, how to invoke it, how it relates to the stable sibling, and that it does not degrade to a fallback. This is enough for an agent to use it correctly.

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%, and the schema already documents the question parameter plus all five aliases. The description only says 'same arguments' without adding parameter-level detail, so it does not increase semantic understanding of the parameters 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 the tool as a beta variant of ask_pipeworx and a universal router over 5,724 tools. It distinguishes itself from stable ask_pipeworx by explicitly stating the beta/experimental status and noting that it currently matches ask_pipeworx exactly.

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 states when to use the tool: 'when you want the newest routing.' It also names the stable router as the comparison baseline and says to use it exactly like ask_pipeworx, giving the agent a concrete usage instruction and an implied alternative.

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