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

Beyond the annotations, the description adds significant behavioral context: it is a full working router with no fallback, currently identical to ask_pipeworx because no candidate is active, and results are compared against the stable router to decide what merges. This fully discloses the tool's experimental and routing behavior.

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 beta identity and clearly structured, but it is somewhat redundant, repeating that it currently matches ask_pipeworx exactly and emphasizing full working router status. Each sentence still adds value, though it could be tightened.

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 router with no output schema, the description covers identity, relationship to the stable version, current active state, usage instructions, and experimental behavior. An agent has enough context to invoke it correctly and understand what will happen.

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 aliases and the main question parameter documented in the schema. The description mentions 'same arguments' but adds no parameter-level detail, which is acceptable because the schema already carries that burden.

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 states a specific purpose: it is a beta version of ask_pipeworx, an identical universal router with the same tools, arguments, and response shape, plus candidate routing improvements. It clearly distinguishes itself from the stable ask_pipeworx and the experimental edge is explicit.

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 says to use it exactly like ask_pipeworx when wanting the newest routing, and it notes the alternative stable router. It does not spell out when not to use it, but the 'experimental edge' framing and candidate comparison provide clear contextual guidance.

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