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

The description discloses behavior beyond the annotations: candidate routing improvements are enabled live when under test, no candidate is currently active, it falls back to nothing, and it remains a full working router. This complements the readOnlyHint and idempotentHint without contradicting them.

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?

Two compact paragraphs front-load the key differentiator and current status. Every sentence carries weight: equivalence to ask_pipeworx, active-candidate status, usage direction, and fallback behavior. The 5,743-tools detail is specific and informative, not padding.

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 simple single-question tool with rich annotations and no output schema, the description covers current behavior, experimental status, fallback, and the relationship to the stable router. The only mild gap is that 'same response shape' is left as a pointer rather than spelled out, but that is acceptable given the tool is explicitly a clone of a sibling.

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 main 'question' parameter plus all aliases. The description adds only the equivalence claim 'same arguments', which is useful context but not new parameter-level semantic detail, so it stays at the high-coverage baseline.

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: a universal router with the same 5,743 tools, arguments, and response shape. It distinguishes itself from the stable sibling by its experimental edge and explicitly states it is a fully working router, not a stub.

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 directional guidance: use it exactly like ask_pipeworx when you want the newest routing, and results will be compared against the stable router. It does not enumerate alternatives or exclusions relative to other siblings, but the current no-candidate status makes the usage context clear.

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