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

Beyond the read-only, idempotent, non-destructive annotations, the description discloses that this is a live experimental edge, that no candidate is currently active, that it therefore currently matches ask_pipeworx exactly, and that it is a full working router with no fallback. These details materially shape agent expectations and do not contradict the annotations.

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 with the beta identity and then covers current status, usage, and the no-fallback caveat in a logical order. It is slightly longer than strictly necessary because the equivalence to ask_pipeworx is stated more than once, but each sentence contributes operational 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 complex universal router with no output schema, the description covers the essential behavior: same arguments and response shape as ask_pipeworx, current candidate state, routing comparison purpose, and no fallback. The main gap is that it does not clarify how this relates to ask_pipeworx_grounded or describe the response shape beyond referencing ask_pipeworx.

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 question documented and q, text, input, prompt, and query listed as aliases. The description adds only that the tool has the same arguments as ask_pipeworx, which is reassuring but does not provide additional parameter semantics beyond what the schema already gives.

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 immediately identifies the tool as the beta variant of ask_pipeworx and specifies that it is an identical universal router with the same 5,738 tools, arguments, and response shape. It clearly differentiates itself from the stable ask_pipeworx by its experimental routing role, so an agent can recognize what it is and how it relates to its siblings.

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 explicitly says to use it exactly like ask_pipeworx when you want the newest routing, and it explains that results are compared against the stable router. This gives a clear usage context, but it does not explicitly say when not to use it or how to choose between this and ask_pipeworx_grounded.

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