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

Annotations already cover safety and idempotency, and the description adds valuable behavioral context: it is an experimental edge, may have a candidate routing improvement active, currently has none, and is a fully working router rather than a fallback stub. This goes beyond the annotations and helps the agent calibrate expectations.

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 dense but well-organized: beta status, identity, current state, usage instruction, and fallback behavior are all covered without excessive padding. Minor redundancy exists between 'identical universal router' and 'currently matches ask_pipeworx exactly,' but it serves the important caveat about experimental changes.

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 beta router with no output schema, the description sufficiently explains behavior, current state, and relationship to the stable tool. The reference to the same response shape as ask_pipeworx compensates for the missing output schema. It is complete enough for an agent to select and invoke the tool 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%, with the question parameter and all aliases documented. The description adds little beyond saying 'same arguments,' which is appropriate since the schema already 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 that this is a beta version of ask_pipeworx acting as an identical universal router with the same tools, arguments, and response shape, while varying only in candidate routing improvements. This clearly identifies what the tool does and differentiates it from the stable ask_pipeworx sibling.

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. It does not explicitly list when not to use it or mention alternatives like ask_pipeworx_grounded, but the guidance is still clear and actionable.

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