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

The description is strong here, adding substantial behavior beyond the readOnly/idempotent annotations: it is experimental, may have candidate routing improvements live, currently has no active candidate and therefore matches ask_pipeworx exactly, and it falls back to nothing because it is a full working router. This gives the agent a clear picture of current and potential behavior without contradicting the annotations.

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 longer than minimal, but every sentence contributes useful context: beta status, identity with ask_pipeworx, the actively-tested candidate behavior, current inactive state, and usage instruction. There is slight redundancy in saying 'identical' and then listing the same tools/arguments/response shape, but it remains focused and front-loaded.

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 tool whose main input is a single documented question parameter, the description is complete enough to invoke it correctly. It explicitly references ask_pipeworx for exact usage and response shape, which is a reasonable pointer to a sibling tool. It could be more self-contained by describing the response shape directly, but the beta-variant framing makes this gap minor.

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%: all six parameters are aliases for 'question' and each is documented in the schema. The description itself adds no parameter-specific detail, but since the schema fully covers semantics, 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 the tool as a beta version of ask_pipeworx and states it is an identical universal router with the same 5,798 tools, arguments, and response shape. It distinguishes itself from its sibling ask_pipeworx by being the experimental edge, so an agent can tell exactly what this tool is and how it relates to the stable variant.

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 gives explicit guidance: use it exactly like ask_pipeworx when you want the newest routing. It also explains that results are compared against the stable router to decide merges, which clarifies the selection context. However, it does not explicitly state when not to use it, such as when stable behavior is preferred.

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