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

The description adds meaningful behavioral context beyond the annotations: it is a live experimental router, candidates may be enabled at any time, currently no candidate is active, and it is a full working router rather than a fallback stub. This helps an agent understand that behavior may vary over time. The read-only, idempotent, and non-destructive annotations are not contradicted.

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 reasonably compact for the complexity it covers: identity, current experimental state, usage instruction, and fallback assurance. Some repetition exists between 'identical universal router' and 'currently matches ask_pipeworx exactly', but the emphasis is useful for a beta tool. It is front-loaded with the core identity.

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 tool is a beta wrapper around ask_pipeworx, the description covers the essential operational context: same tools, same arguments, same response shape, current equivalence to stable, and experimental purpose. No output schema exists, but the phrase 'same response shape' addresses that. It does not detail error behavior or rate limits, but that is acceptable for a router that inherits behavior from a known 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 description coverage is 100%, so the parameters are already fully documented. The description only says 'same arguments' and does not add new semantic detail about how the question should be formatted or what kinds of questions work best. This meets the baseline but adds no extra value.

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 it is a beta version of ask_pipeworx and a universal router with the same tools, arguments, and response shape. This clearly ties its purpose to ask_pipeworx and distinguishes it as the experimental variant. It stops short of explicitly stating 'answer a natural language question', but the title and sibling context make that clear.

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 like ask_pipeworx when wanting the newest routing, and that results are compared against the stable router. It explains when the beta behavior is active and notes the current state matches ask_pipeworx exactly. It does not spell out scenarios where the stable version should be preferred, but the experimental framing implies it.

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