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

Goes well beyond the readOnly/openWorld/idempotent annotations by disclosing the current experimental state: no candidate is active, the last was retired on 2026-07-26, and behavior currently matches ask_pipeworx exactly. It also clarifies that this is a fully functional router with no fallback, removing any ambiguity about reliability.

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 dense but every sentence earns its place: beta status, exact parity with ask_pipeworx, current no-candidate state, usage instruction, experimental evaluation purpose, and fallback clarification. It is front-loaded with the most important identity information and contains no 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?

Covers the experimental-vs-stable relationship, the current routing state, how to invoke the tool, what results are used for, and confirms response-shape parity. Combined with annotations for safety and a fully documented schema, there is nothing critical missing for an agent to call this correctly.

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 the required 'question' parameter and all five aliases already documented in the input schema. The description only adds that ask_pipeworx_beta takes the same arguments as ask_pipeworx, which is a useful pointer but does not add new parameter-level meaning beyond the schema.

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?

Immediately identifies itself as a beta version of ask_pipeworx, an identical universal router over 5,724 tools, and explicitly states it has the same arguments and response shape. This clearly differentiates it from the stable ask_pipeworx while also distinguishing it as an experimental edge rather than a separate, narrower tool.

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?

Directly instructs the agent to use it exactly like ask_pipeworx when the newest routing behavior is desired, and explains that results are compared against the stable router. It names ask_pipeworx as the stable alternative, though it does not state exclusions or address when ask_pipeworx_grounded should be preferred.

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