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

The description goes well beyond the readOnly and idempotent annotations by disclosing the live experimental status, that no candidate is currently active, that it currently matches the stable router exactly, and that it is a full working router rather than a fallback. This is precisely the contextual behavioral detail an agent needs.

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?

Four sentences, each carrying essential information: what it is, its current state, when to use it, and a clarifying caveat. The key beta/stability distinction is front-loaded and no sentence is wasted.

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 absence of an output schema and the nuanced relationship to ask_pipeworx, the description fully covers identity, behavior, current state, usage trigger, and equivalence. Nothing an agent needs to call or interpret this tool is missing.

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%, and the schema already documents the question parameter and all aliases. The description only refers to 'same arguments' without adding parameter-level detail, so the baseline of 3 applies.

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 a beta variant of ask_pipeworx, a universal router over the same 5,743 tools with identical arguments and response shape. It explicitly distinguishes it from the stable ask_pipeworx sibling, so an agent can understand what this tool is and how it differs.

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 instructs using this tool exactly like ask_pipeworx when the newest routing is desired, and explains that results are compared against the stable router. It does not give a hard when-not-to-use list, but the experimental-beta framing and current-equivalence note provide adequate guidance.

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