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

The annotations already mark this as read-only, idempotent, and non-destructive. The description adds important context beyond that: beta status, the fact that results are compared against the stable router, that no routing candidate is active right now, and that this is a fully functional router rather than a fallback stub. This gives a realistic picture of the tool's experimental behavior.

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 essential beta-versus-stable distinction and then provides useful operational context. It is slightly repetitive in saying the tool is identical, matches ask_pipeworx exactly, and is a full working router, but the information density is high and each sentence contributes.

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 full schema coverage, the description provides enough context for an agent to decide when and how to invoke this tool. The lack of an output schema is acceptable because the description explicitly says the response shape matches ask_pipeworx, and the current no-candidate state is clearly disclosed.

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 six parameters and aliases are already well documented. The description only adds that the tool has the same arguments as ask_pipeworx, which is a useful cross-reference but does not add specific semantic detail beyond the schema.

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 a clear resource and verb: this is the beta version of ask_pipeworx, a universal router over 5,908 tools with the same arguments and response shape as the stable version. It explicitly distinguishes itself from ask_pipeworx by noting candidate routing improvements and experimental status.

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 this tool exactly like ask_pipeworx when you want the newest routing, and results are compared against the stable router. It also clarifies that no candidate is currently active, so current behavior matches ask_pipeworx exactly, which directly informs whether an agent should choose this vs the stable sibling.

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