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

Annotations already provide readOnly, openWorld, idempotent, and non-destructive hints. The description adds useful behavioral context about the beta nature, the current absence of an active candidate, and that it is a fully working router rather than a stub. No contradictions with annotations are present.

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 contains useful information but is somewhat repetitive, repeating the 'same as ask_pipeworx' idea in multiple forms, including the parenthetical tool count, arguments, response shape, and the closing reassurance. It could be tightened while preserving the key beta-context and usage guidance.

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 and the tool is explicitly described as identical to ask_pipeworx in response shape, the description provides enough context for an agent to know how to invoke it and what to expect. It could be improved by clarifying what kinds of questions the router handles, but the sibling reference supplies sufficient context.

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?

The input schema fully covers the seven alias parameters, all pointing to the same natural-language question. The description adds no additional parameter-level detail beyond saying 'same arguments as ask_pipeworx,' so it does not elevate above the baseline provided by high schema coverage.

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 ask_pipeworx_beta as the beta version of ask_pipeworx, a universal router with the same tools and arguments, and distinguishes it from the stable sibling by mentioning candidate routing improvements. It could have been more self-contained about what the router actually does, but the reference to ask_pipeworx makes the purpose reasonably clear.

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?

The description explicitly states when to use this tool versus ask_pipeworx: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also clarifies the current state (no active candidate, so behavior matches ask_pipeworx), giving concrete usage guidance.

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