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

Beyond the readOnly/openWorld/idempotent annotations, the description discloses important dynamic behavior: candidate routing improvements are enabled live when under test, no candidate is currently active, and the tool has no fallback because it is a full working router. It also states the current parity with ask_pipeworx and the experimental nature, which is valuable context for an agent deciding whether to use it.

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 well-structured: each sentence carries a distinct purpose—identity, current state, usage guidance, and fallback clarification. It front-loads the key fact that this is a beta version of ask_pipeworx and avoids filler.

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 beta variant with one required string parameter and full schema coverage, the description covers what the tool is, when to use it, how it differs from the stable version, and its current live status. The main gap is that the response shape is only referenced as 'same response shape' rather than described, but since the tool is explicitly a variant of ask_pipeworx, this is reasonably complete.

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 input schema already provides 100% description coverage for the question parameter and all five aliases. The description adds no new parameter-level semantics beyond saying 'same arguments' as ask_pipeworx, so the schema carries the burden and the description does not need to compensate.

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 that behaves as an identical universal router with the same 5,921 tools, arguments, and response shape. It distinguishes it from the stable ask_pipeworx by the live candidate-routing behavior. However, it relies on the reader knowing ask_pipeworx and never directly states the underlying user-facing action ('ask a natural-language question and get a routed answer').

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 an explicit usage rule: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also explains the comparison against the stable router and the merge decision purpose, which tells the agent exactly when this variant is appropriate instead of the standard ask_pipeworx.

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