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

This goes well beyond the annotations by disclosing the experimental nature, live candidate routing under test, the current inactive status with a specific date, and the fact that results are compared against the stable router. The statement 'Falls back to nothing — this IS a full working router' is especially transparent about availability and reliability.

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 efficient and well-structured: it front-loads identity and parity, then explains current status and usage, and ends with a reassuring fallback statement. The level of detail is appropriate for a tool with experimental 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?

Given the schema and annotations, the description covers the key operational aspects: what the tool is, whether it is currently different from stable, and how to invoke it. It relies on ask_pipeworx for the exact response shape, which is reasonable given the sibling relationship but makes it not entirely standalone.

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 parameter schema already documents the arguments. The description only adds 'same arguments' as ask_pipeworx and does not explain any parameter semantics, aliases, or question-format expectations beyond the 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 clearly identifies the tool as a beta variant of ask_pipeworx and an identical universal router over 5,738 tools, which conveys its role and scope. It distinguishes it from the stable ask_pipeworx, though it does not fully define the underlying 'ask' behavior and does not contrast it with 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?

The description explicitly directs the agent to use it exactly like ask_pipeworx when newest routing is desired, and notes the current parity since no candidate is active. It does not give explicit when-not-to-use instructions or compare against ask_pipeworx_grounded, but the usage intent is clear.

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