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

Beyond the annotations, the description discloses that this is a live experimental edge, that candidate routing improvements may be enabled during testing, that no candidate is currently active, and that it falls back to nothing because it is a fully working router. This is valuable behavioral context an agent cannot derive from annotations alone.

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 information-dense and well-structured: it front-loads the beta relationship, then covers identity, current status, usage, comparison behavior, and non-fallback nature. Every sentence earns its place and there is no filler.

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 tool with a single required string parameter, no output schema, and strong annotations, the description covers everything an agent needs: operational status, exact equivalence to ask_pipeworx now, when to prefer it, and what happens when a candidate is under test. Nothing critical is missing.

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%, and the schema already documents each of the six parameters as aliases for the single required question parameter. The description only says 'same arguments' without adding per-parameter meaning, so it neither harms nor improves on the schema. Baseline 3 is appropriate.

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 defines ask_pipeworx_beta as the beta version of ask_pipeworx: an identical universal router over 5,743 tools with the same arguments and response shape. It explicitly distinguishes it from the stable router and names the sibling behavior, so an agent can tell exactly what tool this is and how it relates to 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?

The description gives explicit usage guidance: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also explains that results are compared against the stable router to decide merges, and that no candidate is active right now, which tells the agent when this variant is and isn't meaningfully different.

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