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

Beyond the annotations, the description discloses crucial runtime behavior: candidate routing improvements may be live, none are active as of a specific date, the tool currently matches ask_pipeworx exactly, and it does not fall back to anything—it is a full working router. This is exactly the kind of behavioral nuance that annotations cannot express.

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 front-loaded: first tells what the tool is, then how to use it, then the no-fallback behavior. Some operational detail like the exact retirement date adds a slightly temporal that could go stale, but it is still placed efficiently and earns its place.

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 one-parameter read-only tool with no output schema, the description is largely complete: it covers the experimental nature, current parity with the stable router, and how to invoke it. It relies on ask_pipeworx as the reference point for domain behavior, but since that is a visible sibling, the agent has enough 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 fully documents the one required question parameter and its aliases. The description only says the tool accepts the same arguments as ask_pipeworx, which reinforces usage but adds no new parameter-level meaning.

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 the beta version of ask_pipeworx, an identical universal router with the same 5,801 tools, arguments, and response shape. It explicitly contrasts with the stable ask_pipeworx and names ask_pipeworx_grounded as a sibling, so an agent can distinguish it without opening schemas.

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 gives an explicit condition: use it exactly like ask_pipeworx when you want the newest routing, and explains that results are compared against the stable router. It does not explicitly enumerate when not to use it or mention ask_pipeworx_grounded, but the stable-vs-beta choice is clear enough.

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