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

The description discloses important behavioral traits beyond the annotations: it is an experimental router that may enable candidate routing improvements live, currently has no active candidate, and is compared against the stable router. It also clarifies 'Falls back to nothing — this IS a full working router', preventing misinterpretation of beta as a stub.

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 a focused paragraph that front-loads the core identity and then addresses current state, usage, and assurances. Each sentence adds value, though there is slight redundancy between 'currently matches ask_pipeworx exactly' and the later 'Falls back to nothing' clarification.

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 without an output schema, the description provides everything an agent needs: it is a full working router, accepts the same arguments, returns the same response shape as ask_pipeworx, and is currently identical to the stable version. The beta caveats and comparison purpose are also clearly stated.

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%—all parameters are documented as aliases for 'question'. The description adds a cross-reference to 'same arguments' as ask_pipeworx, which is useful but does not provide new parameter-level semantics. This meets the baseline for fully covered schemas.

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 the tool is a beta version of ask_pipeworx: an identical universal router with the same 5,767 tools, arguments, and response shape. It also differentiates it from the stable ask_pipeworx by emphasizing the experimental routing candidate and that it currently matches ask_pipeworx exactly.

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 'Use it exactly like ask_pipeworx when you want the newest routing', naming the alternative and the condition for selection. It does not explicitly state when-not-to-use or caution against production use, but the beta framing implies this.

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