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

The annotations already mark it read-only and idempotent, and the description adds valuable context beyond them: it is a live experimental edge, may have a routing candidate enabled, currently matches stable behavior because the last candidate was retired, and has no fallback. This prevents the agent from mistaking it for a partial or stub 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 longer than average but each sentence contributes meaningful information: beta status, current candidate state, usage instruction, and confirmation that it is a fully working router. The date and 'falls back to nothing' phrasing are slightly verbose but do not obscure the message.

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 an experimental variant of a known stable router, the description covers current behavior, identity, safety profile, and usage context well. It relies on 'same response shape' rather than describing the actual return format, but the existence of the ask_pipeworx sibling makes this reference reasonable.

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?

All six parameters, including the five aliases, are fully documented in the input schema, so the description carries little parameter burden. The only addition is that arguments are the same as ask_pipeworx, which is useful context but not a deeper semantic explanation.

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 states this is a beta variant of ask_pipeworx, an identical universal router over 5,798 tools with the same arguments and response shape. It clearly distinguishes itself from the stable ask_pipeworx sibling while communicating the core function of routing a question to tools.

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 you want the newest routing, and notes results are compared against the stable router for merge decisions. This gives a clear when-to-use condition and implies the stable router as the alternative, though it does not spell out a direct when-not-to-use case.

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