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

Even with annotations already marking it read-only, open-world, idempotent, and non-destructive, the description adds important behavioral context: it is a fully working experimental router, may have candidate improvements enabled during tests, and currently matches ask_pipeworx exactly because no candidate is active. This is transparent about the variability of its behavior over time.

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 a compact paragraph with four sentences that each deliver useful information: identity, current state, usage instruction, and reliability reassurance. There is mild redundancy around 'same as ask_pipeworx,' but it remains efficient and well-organized.

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 the absence of an output schema, the description sufficiently covers what the tool is, how it behaves experimentally, and how it relates to the stable ask_pipeworx sibling. It could be slightly more complete by explicitly naming when to prefer the stable version, but it already implies that strongly.

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%, so the schema already documents the question parameter and all aliases. The description adds no parameter-specific detail beyond saying it uses the same arguments as ask_pipeworx, which is consistent but not enriching beyond the schema 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 version of ask_pipeworx and explains it is a universal router with the same 5,767 tools, arguments, and response shape. It distinguishes itself from the stable sibling by the live candidate routing improvements, leaving no ambiguity about what the tool is.

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?

The description explicitly says to use it exactly like ask_pipeworx when wanting the newest routing, and explains that results are compared against the stable router to decide merges. This gives clear when-to-use guidance and implicitly signals that ask_pipeworx is the stable alternative.

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