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

Beyond the annotations, the description discloses that routing behavior may change live when a candidate is under test, that no candidate is currently active so it currently matches ask_pipeworx exactly, and that it is a full working router with no fallback. This is valuable experimental-context information that annotations alone do not provide.

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 identity and the key identical-router fact before covering current status, usage, and fallback behavior. There is minor overlap between 'whenever one is under test' and the sentence saying no candidate is active now, but 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?

Although there is no output schema, the description states that the response shape is identical to ask_pipeworx, which adequately tells an agent what to expect. Combined with strong annotations and a single required natural-language parameter, the description gives enough context for correct invocation.

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% and the schema already documents the aliases and the required 'question' parameter. The description only says 'same arguments' and does not add parameter-level meaning, so the baseline score of 3 is appropriate.

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 'Beta version of ask_pipeworx' and an 'identical universal router' with the same tools, arguments, and response shape, making its purpose as an experimental variant of ask_pipeworx explicit. It distinguishes itself from the stable router and sibling tools by framing it as the edge version with candidate routing changes.

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?

'Use it exactly like ask_pipeworx when you want the newest routing' gives an explicit usage condition, and the phrase 'results are compared against the stable router' clarifies when this variant is relevant. It does not spell out explicit exclusion cases, but the stable-vs-experimental distinction is clear enough for an agent.

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