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

Beyond the strong read-only, idempotent, non-destructive annotations, the description adds valuable behavioral context: it is experimental, candidate routing may be live, no candidate is active right now, and it currently behaves exactly like ask_pipeworx. It also clarifies that it is a full working router with no fallback, removing a likely misconception about a beta tool.

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 compact and front-loaded: identity first, then current state, usage instruction, and a clarifying reassurance about fallback. Every sentence adds useful context and none is wasted.

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 simple schema with one required natural-language input and strong safety annotations, the description covers identity, current behavior, usage, and experimental risk. It does not spell out the output format, but it does state that the response shape is identical to ask_pipeworx, which is likely sufficient given 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%, so the input schema already documents all six parameters as aliases for question. The description only references 'same arguments' as ask_pipeworx, which adds no new parameter-level meaning beyond the schema.

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 this as a beta variant of ask_pipeworx: an identical universal router over the same tools, arguments, and response shape, distinguished by live testing of candidate routing improvements. It positions the tool against its stable sibling ask_pipeworx without ambiguity.

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 to decide merges. It lacks an explicit when-not-to-use or alternative selection rule for grounded/stable variants, but the guidance is largely clear.

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