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

The description clearly discloses that this is a full working router with no fallback, that candidate routing improvements are live only when under test, and that no candidate is currently active. It adds meaningful behavioral context beyond the readOnly/idempotent annotations, including the retire date and exact current parity with the stable version.

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 information-dense and front-loads the most important fact: this is the beta version of ask_pipeworx. Each sentence contributes meaningful context about identity, behavior, status, and usage. There is minor redundancy between 'identical', 'same 5,801 tools...', and 'use it exactly like ask_pipeworx', but it does not hurt clarity.

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?

The description covers the tool's identity, experimental status, current parity, usage, fallback behavior, and evaluation purpose. It adequately compensates for the lack of an output schema by stating that the response shape matches ask_pipeworx. It does not fully define what ask_pipeworx itself does, but the sibling context makes that gap acceptable.

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?

The schema already documents the q, text, and input parameters as aliases for question, giving it full schema coverage. The description adds no further parameter semantics beyond noting that arguments are identical to ask_pipeworx. This matches the baseline for high schema coverage.

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, an identical universal router with the same 5,801 tools, arguments, and response shape. It distinguishes the tool from its stable sibling by emphasizing the experimental routing improvements. However, it relies on knowledge of ask_pipeworx to fully understand the core purpose.

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 says to use it exactly like ask_pipeworx when the agent wants the newest routing, which is a clear usage condition. It also explains that this is the experimental edge and that results are compared against the stable router. It does not explicitly say when not to use it or mention alternatives like ask_pipeworx_grounded.

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