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

Beyond the read-only, idempotent, open-world annotations, the description adds critical behavioral context: candidate routing improvements are enabled live only when under test, no candidate is active right now, and this is a full working router with no fallback. It also states the current state matches ask_pipeworx exactly, giving the agent accurate expectations for invocation.

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 dense but each sentence earns its place: identity, current status, usage guidance, and a reassurance against a likely misconception about fallback behavior. It is front-loaded with the key identity and ends with the clarifying full-router note.

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 universal router with no output schema, the description provides sufficient context: what it is, how it relates to ask_pipeworx, what is currently active, and how to use it. The absence of an output schema is mitigated by stating that the response shape is identical to ask_pipeworx, which an agent can consult if needed.

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 schema already fully documents the question parameter and its aliases. The description adds no specific parameter-level meaning beyond saying the beta shares the same arguments as ask_pipeworx, which is consistent with the baseline expectation when 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 clearly identifies this as the beta version of ask_pipeworx, an identical universal router with the same 5,743 tools, arguments, and response shape. It distinguishes the tool from its sibling ask_pipeworx by framing it as the experimental edge with candidate routing improvements.

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 exactly like ask_pipeworx when you want the newest routing, and mentions that results are compared against the stable router. The alternative (ask_pipeworx) is named directly, and the statement that no candidate is currently active clarifies when behavior matches the stable version exactly.

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