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

The description adds substantial transparency beyond the annotations: it discloses the experimental nature, whether a candidate is currently active, that it currently matches ask_pipeworx exactly, that it is a full working router, and that it falls back to nothing. This is valuable for an agent deciding whether to trust or expect experimental behavior.

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 appropriately sized and front-loaded, starting with the tool's identity as a beta version of ask_pipeworx. Every sentence earns its place: identity, current state, usage guidance, and fallback behavior are all covered without unnecessary filler.

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 complex routing tool, the description is complete: it defines the tool, current behavior, how to invoke it, what it returns (same response shape), and what it does not fall back to. Annotations cover safety and idempotence, and the schema covers parameters, so nothing essential is missing.

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 has 100% coverage and documents the question parameter plus aliases. The description adds no real parameter-level semantics beyond saying it takes the same arguments as ask_pipeworx, which is not independently useful. Baseline 3 is appropriate since the schema already carries the parameter meaning.

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 states that ask_pipeworx_beta is a beta version of the ask_pipeworx universal router, with the same tools, arguments, and response shape, plus candidate routing improvements. It explicitly distinguishes it from the stable ask_pipeworx and grounded variants by describing itself as the experimental edge.

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 the newest routing is desired, and explains that results are compared against the stable router. It does not explicitly state when not to use it or mention grounded alternatives, though the context is clear enough for selection.

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