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

Annotations already declare read-only, open-world, idempotent, non-destructive behavior, and the description adds significant context: it is a full working router, currently identical to ask_pipeworx, candidate routing changes can be live under test, and results are compared against the stable router. No contradiction with annotations.

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?

Four sentences convey identity, current state, usage, and caveat without unnecessary filler. The differentiator is front-loaded, and the emphasis on being a full working router is useful, though slightly redundant.

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 covers beta status, current parity with ask_pipeworx, usage intent, and the experimental comparison process. Since no output schema exists, the claim of 'same response shape' provides adequate context, though the exact return format is not detailed.

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 description coverage is 100%, with all six parameters documented as aliases for the required 'question' parameter. The description adds no parameter details beyond what the schema provides, so the baseline 3 applies.

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?

Description clearly identifies ask_pipeworx_beta as a beta version of ask_pipeworx: a universal router with the same 5,798 tools, same arguments, and same response shape. The explicit sibling reference and 'universal router' phrasing make its function and scope immediately distinguishable.

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 newest routing is desired and frames it as the experimental edge. It does not explicitly state when not to use it, but the comparison to the stable router strongly implies the alternative.

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