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

Annotations already mark the tool as read-only, idempotent, and non-destructive, so the description does not need to restate those. It adds valuable behavioral context: no candidate is currently active, the tool currently matches ask_pipeworx exactly, and it is a fully working router with no fallback. This is exactly the kind of stateful experimental nuance 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 compact and information-dense, with each sentence contributing: identity, current experimental state, usage guidance, and fallback behavior. It is front-loaded with the key fact that this is the beta version of ask_pipeworx. No filler or redundancy.

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 the simple one-required-string input schema, rich annotations, and no output schema, the description is fully sufficient for invocation. It explains current behavior, how to use it, and the experimental context. An agent has everything needed to call it correctly and interpret its role relative to the stable router.

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% and clearly documents the single required question parameter plus all aliases. The description adds only that the arguments match ask_pipeworx, which is useful but not necessary for parameter understanding. The schema already carries the semantic weight here.

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 the beta version of ask_pipeworx, with the same universal routing behavior, same arguments, and same response shape. It also distinguishes itself from the stable router by its live-testing purpose. An agent can immediately understand what tool this is and how it relates to siblings.

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 explains that results are compared against the stable router. This gives clear usage context for the primary sibling. It does not mention ask_pipeworx_grounded or when not to use it, but the guidance is still sufficient for correct selection.

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