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

The description goes well beyond the readOnly/idempotent annotations by explaining the live experimental nature: candidate improvements are 'enabled live whenever one is under test', and currently no candidate is active so it matches ask_pipeworx exactly. It also makes the evaluation purpose transparent (results compared against the stable router). This gives useful behavioral context that annotations alone do not provide.

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 core message—beta router identical to ask_pipeworx—is front-loaded, which is good. But several sentences spend time on internal process details like the 2026-07-26 retirement date and the merge-decision flow, which are not needed to invoke the tool correctly. Overall it is understandable but more verbose than necessary.

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?

With no output schema, the description only refers to the 'same response shape' as ask_pipeworx without defining what that response is, so an agent must consult the sibling tool for return format details. It adequately covers invocation (a single required question field) and the safety profile via annotations, but is not fully self-contained.

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% — q, text, input, and question are each documented as aliases for the required question. The description adds no parameter-level detail beyond saying 'same arguments' as ask_pipeworx, which does not clarify the aliases or input semantics any further.

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?

Describes ask_pipeworx_beta as a 'universal router' with the 'same 5,908 tools, same arguments, same response shape' as ask_pipeworx, giving a concrete resource and scope. It establishes its experimental identity as a beta version of the sibling, which clearly differentiates it. However, it never directly states the action it performs (e.g., routing a question to the best tool), leaning on the sibling name for that.

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 'Use it exactly like ask_pipeworx when you want the newest routing', giving a clear condition for selecting this tool over the stable sibling. It also reassures that it is a 'full working router' that 'falls back to nothing', so an agent can fully rely on it. It doesn't discuss alternatives like ask_pipeworx_grounded, but the primary alternative is named and differentiated.

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