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

Annotations already cover read-only, idempotent, and non-destructive behavior. The description adds valuable context beyond those annotations: no candidate routing improvement is currently active, the tool currently matches ask_pipeworx exactly, and it is a full working router rather than a fallback.

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 three sentences long and front-loaded with the tool's identity and relationship to ask_pipeworx. Each sentence adds relevant information about current behavior, usage, or experimental status. It is slightly dense but not bloated.

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 alias of a known sibling tool, the description is largely complete: it explains current behavior, relationship to the stable router, how to invoke it, and that it is a full router. It does not describe the response format, but it references the same response shape as ask_pipeworx, which is an acceptable reference given the sibling 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?

Schema coverage is 100% and the input schema already documents all aliases for the question parameter. The description only adds 'same arguments as ask_pipeworx,' which adds no new parameter-level meaning beyond what the schema provides. Baseline 3 is appropriate.

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 a beta variant of ask_pipeworx: an identical universal router with the same 5,743 tools, arguments, and response shape. It distinguishes itself from the stable sibling by emphasizing the experimental edge, though it assumes some understanding of what ask_pipeworx does.

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 says to use it exactly like ask_pipeworx when you want the newest routing and explains that results are compared against the stable router. It provides a clear use case and a comparison to the stable sibling, though it does not explicitly state conditions where the stable version should be preferred.

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