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

This description goes well beyond the annotations by disclosing the experimental nature, the candidate-testing mechanism, the current inactive-candidate state with a date, the fact that results are compared against the stable router, and that there is no fallback — it is a fully functional router. This gives an agent a realistic picture of how behavior may vary without contradicting the read-only and idempotent hints.

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 compact and front-loaded, leading with the beta relationship to ask_pipeworx and the universal-router behavior. The specific date and tool count add useful context without bloating the text, though a tiny bit of redundancy exists between the first sentence and 'use it exactly like ask_pipeworx'.

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 single-question-parameter tool with rich annotations, the description covers the essential context: beta status, current parity with the stable router, experimental candidate behavior, and the absence of a fallback. It does not describe the response shape in detail, but it explicitly points to ask_pipeworx's response shape, which is sufficient given the sibling context.

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%, with all parameters documented as aliases for 'question', so the description does not need to add parameter-level details. The description mentions 'same arguments' but leaves parameter meaning to the schema, which is adequate at the 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 the tool as the beta version of ask_pipeworx, a universal router with the same 5,798 tools and response shape, which distinguishes it from the stable sibling. It is concrete about what the tool is and what it does, without being a tautology.

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 it notes the current no-candidate state means it behaves identically to ask_pipeworx. It does not explicitly state when to avoid it in favor of the stable router, though that is strongly implied.

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