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

Beyond the annotations' read-only/idempotent safety profile, the description adds genuinely useful behavioral context: candidate routing improvements are enabled live, no candidate is currently active as of a stated date, behavior currently matches ask_pipeworx exactly, and results are compared against the stable router. This is the kind of operational state an agent needs before calling an experimental variant.

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 current-state caveat, and every sentence contributes to the overall message. The specific retirement date and 'outcome evidence' phrasing add slight verbosity, but the structure is logical and the key caveat is prominent.

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?

Given the rich annotations and lack of an output schema, the description covers the critical selection context: what this tool is, how it currently behaves, when to use it, and that its response shape matches ask_pipeworx. It does not enumerate response fields or error behavior, but the universal-router framing and sibling reference make it adequate for 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?

The input schema fully documents all six parameters and the question alias relationship at 100% coverage, so the schema does the heavy lifting. The description only adds 'same arguments' without enriching parameter meaning, which matches the baseline of 3.

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 and a universal router covering 5,724 tools with the same response shape, which distinguishes it from the stable sibling. It does not explicitly describe the core 'answer a question' behavior, instead relying on the sibling name and routing concept, so it is clear but slightly indirect.

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 you want the newest routing, and reassures that this is a full working router. It does not spell out when to prefer the stable ask_pipeworx or the grounded variant, so the exclusion direction is only partially covered.

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