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

While annotations already mark this as read-only, idempotent, and non-destructive, the description adds meaningful context: it explains that candidate routing improvements may be live, that no candidate is currently active, that behavior currently matches ask_pipeworx, and that it is a fully working router with no fallback. This is exactly the kind of behavioral nuance the annotations do not convey.

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 every sentence earns its place: identity, current state, usage instruction, comparison purpose, and reassurance that it is fully functional. The key beta-vs-stable distinction is front-loaded.

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 router with no output schema, the description covers what the tool does, its current experimental status, how it relates to the stable version, and how its results are evaluated. An agent can correctly decide when and how to call it without ambiguity.

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%, and the schema already documents the question parameter plus all aliases. The description adds only that arguments are the same as ask_pipeworx but does not need to repeat schema content; the baseline of 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 the tool as a beta variant of ask_pipeworx, an identical universal router with the same 5,767 tools, arguments, and response shape. This distinguishes it from the stable ask_pipeworx and grounded variants by emphasizing its experimental routing 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 wanting the newest routing and notes that results are compared against the stable router. It does not list explicit exclusions or when to prefer ask_pipeworx over the beta, but the experimental edge and comparison context provide clear usage direction.

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