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

Beyond the annotations, it discloses that candidate routing improvements may be active live, that none is currently active, that the last was retired on outcome evidence, and that it falls back to nothing—it is a fully functioning router, not a degraded proxy. This is strong behavioral context.

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 appropriately sized and front-loaded: the first sentence establishes identity and relationship to ask_pipeworx, and later sentences clarify status and usage. There is minor redundancy between 'identical' and 'currently matches ask_pipeworx exactly,' but it is not wasteful enough to penalize heavily.

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?

The description tells an agent everything essential to invoke it correctly: same arguments as ask_pipeworx, same response shape, experimental status, and current parity with the stable router. With no output schema, the mention of the same response shape compensates well; only a brief note about the grounded alternative would round it out.

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 documents all parameters at 100% coverage, including the required 'question' and all aliases. The description's mention of 'same arguments' adds no new parameter-level meaning, so the baseline 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 is specific: it is the beta version of ask_pipeworx, a universal router exposing the same 5,724 tools, arguments, and response shape as the stable version. It clearly distinguishes itself as the experimental edge, which separates it from its sibling tools like ask_pipeworx and 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 gives explicit guidance: 'Use it exactly like ask_pipeworx when you want the newest routing' and clarifies that results are compared against the stable router. It does not explicitly say when not to use it or when to prefer ask_pipeworx_grounded, but the main selection criterion—preference for the newest routing—is clear.

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