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

Beyond the read-only and idempotent annotations, the description discloses meaningful operational behavior: candidate routing improvements are enabled live during tests, no candidate is currently active, and the beta currently matches the stable router exactly. It also clarifies that it does not fall back to another tool — it is a fully working router.

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 longer than average but each sentence adds useful context: variant identity, current experimental status, usage instruction, and reassurance that it is a complete router. The date-specific retirement detail is slightly noisy but not wasteful.

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 no output schema, the description still tells the agent everything needed to invoke it: same arguments as ask_pipeworx, same response shape, current live behavior, and how to use it. The tool's complexity is well covered.

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%, and every parameter is already documented as an alias for 'question'. The description adds no new semantic meaning about parameters beyond saying the tool takes 'same arguments' as ask_pipeworx, so the schema carries the load.

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 states clearly that this is a beta variant of ask_pipeworx, a universal router with the same 5,798 tools, arguments, and response shape. It differentiates itself from the stable sibling by emphasizing its experimental role, so an agent can tell it apart from ask_pipeworx and ask_pipeworx_grounded.

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 gives explicit guidance: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also explains that results are compared against the stable router to decide merges. However, it does not explicitly state when NOT to use it, such as preferring the stable router for production-sensitive calls.

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