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

The description adds substantial behavioral context beyond the annotations: candidate routing improvements are enabled live, no candidate is currently active, it currently matches ask_pipeworx exactly, and it is a full working router rather than a fallback. This makes the tool's experimental and dynamic nature clear.

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 and information-rich, covering parity, current experimental state, usage, and non-fallback nature. It is slightly verbose but every sentence contributes useful context.

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?

Given the one required parameter and no output schema, the description covers the most important operational details: current parity, experimental routing, and how to use it. It references the same response shape as ask_pipeworx, though it does not spell out that response shape directly, which is a minor gap.

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%, so the schema already documents the question parameter and its aliases fully. The description adds no additional parameter-level semantics beyond saying it uses the same arguments as ask_pipeworx, which is adequate but not enriching.

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 a beta version of ask_pipeworx and a universal router over 5,724 tools, with the same arguments and response shape. It distinguishes itself from the stable ask_pipeworx by its experimental routing behavior, but it does not contrast with all siblings, notably ask_pipeworx_grounded.

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?

It explicitly says to use it exactly like ask_pipeworx when the user wants the newest routing, and notes that results are compared against the stable router. However, it does not state when not to use it or mention the grounded sibling as an alternative.

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