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

Beyond the annotations, the description reveals that this is an experimental beta, that candidate routing improvements are enabled live only when under test, that no candidate is currently active, and that it does not fall back to a partial implementation. This is substantial 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 somewhat long but information-dense. Each sentence contributes key context: identity/equivalence, current runtime status, usage guidance, and clarification that it is a full working router. A shorter version could trim redundancy, but structure is logical 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 complex universal router with no output schema, the description covers what the tool is, how to invoke it, its current equivalence to the stable version, its experimental nature, and its non-fallback behavior. It leaves no critical operational gap for an agent deciding whether and how to call it.

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 schema already documents the single meaningful parameter (`question`) and all five aliases with 100% coverage. The description adds only 'same arguments' without further semantic detail, so it adds no value beyond the structured 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?

The description is explicit: this is the beta version of ask_pipeworx, an identical universal router over the same 5,724 tools, with candidate routing improvements. It clearly differentiates itself from the stable ask_pipeworx sibling by framing itself as the experimental edge.

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 states when to use it: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also explains the comparison against the stable router. It does not explicitly enumerate when-not-to-use cases, but the beta/experimental framing implies stable use should go to ask_pipeworx.

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