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

Even though annotations already mark this as read-only, idempotent, and non-destructive, the description adds important operational behavior: candidate routing improvements are enabled live only when under test, none is active right now, and results are compared against the stable router to decide merges. It also preempts the concern about fallback behavior with 'Falls back to nothing — this IS a full working router.'

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-loads the core beta-identity statement first. It is slightly repetitive across 'identical universal router', 'currently matches ask_pipeworx exactly', and 'Use it exactly like ask_pipeworx', but each sentence still contributes meaningful context about usage, state, or experimental purpose.

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 single-parameter universal router with strong annotations, this description is complete. It tells the agent what the tool does, how it differs from the stable sibling, when to use it, what to expect in terms of arguments/response shape, and that it is a fully functional router rather than an incomplete experimental stub.

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%, so the schema already fully documents the question field and all five aliases. The description mentions 'same arguments' but adds no new parameter-level meaning beyond the schema, which fits the baseline of 3 for high coverage.

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?

States a specific verb and resource: it is a beta version of ask_pipeworx that works as an identical universal router with 5,743 tools and the same arguments/response shape. It clearly distinguishes itself from the stable router while also describing its exact current state versus ask_pipeworx.

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?

Directly instructs when to use it: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also names the stable ask_pipeworx as the comparison baseline and explicitly clarifies that this is a full working router and not a fallback, ruling out a common misuse.

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