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

The description goes beyond the benign annotations by revealing the current experimental state: no candidate is active, so behavior currently matches ask_pipeworx exactly. It also clarifies that it falls back to nothing and is a full working router, not a stub or proxy. This is valuable behavioral context the annotations do not provide.

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 front-loaded with the key fact that this is the beta version and wastes little space. It is slightly redundant in repeating that it is identical/same, but every sentence contributes useful information about current status, usage, and fallback behavior.

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 whose main job is routing, the description is complete enough: it explains the current parity with ask_pipeworx, the experimental nature, and how results are used. It does not spell out the response structure, but it points to the stable counterpart's response shape, which is adequate context.

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% coverage, including clear descriptions for the question field and its aliases. The description adds no new parameter-level semantics beyond saying the arguments are the same as ask_pipeworx, which is sufficient but does not exceed the schema baseline.

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 states that it is an identical universal router with the same tools, arguments, and response shape. It also explicitly distinguishes it from the stable router by calling it the experimental edge, making its purpose unambiguous.

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 explicit usage guidance: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also notes that results are compared against the stable router and that no candidate is currently active, which directly informs when and why an agent should choose this tool.

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