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

Annotations already mark it read-only, open-world, idempotent, and non-destructive; the description adds substantial behavioral context on top: it is the experimental edge, candidate routing improvements are enabled live, no candidate is currently active, and it is a fully working router rather than a fallback stub. This is exactly the kind of status and caveat information an agent needs.

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 identity and purpose, and every sentence contributes useful information: beta status, current state, usage instruction, and fallback clarification. It is slightly longer than strictly necessary due to repeated emphasis that it matches ask_pipeworx, but the details are earned.

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 no output schema, the description references the response shape indirectly by saying it is the same as ask_pipeworx, which is adequate only if the agent already understands ask_pipeworx. It also doesn't list the 5,798 tools, but that is not needed to invoke the tool. Overall it gives enough context to select and call it correctly.

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%, so the schema already documents all six parameters and aliases. The description only says 'same arguments' and adds no additional parameter-level semantics, which matches the baseline of 3 when the schema carries the 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 opens by naming the tool as 'Beta version of ask_pipeworx' and specifies its exact role: an identical universal router with the same 5,798 tools, arguments, and response shape, plus experimental routing improvements. This clearly differentiates it from the stable ask_pipeworx sibling while still stating what it actually does.

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 gives an explicit usage condition: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also names the stable alternative and explains the comparison/evaluation purpose. It does not explicitly mention when not to use it relative to ask_pipeworx_grounded, but the beta-vs-stable guidance is sufficient.

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