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

Beyond the annotations, the description adds valuable behavioral context: it is a full working router with no fallback, it may run candidate routing improvements live, and no candidate is currently active so it currently matches ask_pipeworx exactly. This is strong transparency about the experimental, time-varying nature of the tool.

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 moderately sized and front-loads the core identity first, then the current status, usage guidance, and caveat. Each sentence contributes useful information, though some phrasing is slightly redundant with the earlier statements about being identical and currently matching ask_pipeworx.

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 that there is no output schema, the description does well by stating the response shape matches ask_pipeworx and that this is a fully operational router, not a stub. It is complete enough for an agent already familiar with ask_pipeworx; for a completely new agent, the response shape and routing behavior would still need to be inferred from the sibling tool.

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 schema already fully documents the question parameter and its aliases. The description adds no new parameter-level meaning, which is acceptable at high coverage; hence the baseline score of 3.

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 variant of ask_pipeworx: a universal router with the same 5,743 tools, arguments, and response shape. It distinguishes itself from the stable ask_pipeworx by mentioning candidate routing improvements, though it does not independently define what 'ask_pipeworx' fundamentally does for an agent encountering the family for the first time.

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 you want the newest routing, and notes that results are compared against the stable router. This gives a clear selection condition relative to the stable sibling, though it does not address when to prefer ask_pipeworx_grounded or when the beta should not be used.

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