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

Beyond the readOnly/openWorld/idempotent annotations, the description discloses the current experimental state: no candidate is active, it currently matches ask_pipeworx exactly, and it 'falls back to nothing.' This gives agents crucial runtime-behavior context that annotations cannot convey.

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 beta identity and core behavior, then covers current status, usage, and reassurance. It is mostly efficient, though phrases like 'currently matches ask_pipeworx exactly' and 'this IS a full working router' are 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?

For a simple natural-language router with rich annotations and full schema coverage, the description covers identity, current state, usage, and relationship to the stable sibling. It references the same response shape but doesn't detail it; given the reference to a known sibling, this is a minor gap rather than a blocking omission.

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%, with all aliases documented. The description adds only 'same arguments' as a reference to ask_pipeworx, which provides no additional parameter-level meaning. This is an appropriate baseline-3 case where the schema carries the semantic load.

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 verb and resource: this is the beta version of ask_pipeworx, an identical universal router over 5,721 tools with the same arguments and response shape. It clearly distinguishes itself from the stable ask_pipeworx sibling by emphasizing its experimental routing role.

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 a clear usage condition: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also names the stable router as the comparison baseline and clarifies this is a full working router, not a stub. It lacks an explicit when-not-to-use instruction for stability-sensitive cases, so it misses the full 5.

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