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

Beyond the readOnly/openWorld/idempotent annotations, the description discloses the beta nature, live candidate routing improvements, the current absence of an active candidate, the comparison process against the stable router, and the fact that it is a full working router with no fallback. This is rich, honest behavioral context.

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 with the core beta router concept and uses compact parentheticals effectively. Some redundancy exists between 'identical universal router', 'currently matches ask_pipeworx exactly', and 'full working router', but the overall length is justified for a beta tool.

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?

The description fully covers what the tool is, its current operational status, how to use it relative to the stable version, and what happens to its results. The absence of an output schema is mitigated by the statement that the response shape is identical to ask_pipeworx.

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%, with all parameters documented as aliases for question, so the description does not need to explain them. It mentions 'same arguments' as ask_pipeworx but adds no parameter-level meaning beyond what the schema already provides.

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 identifies the tool as the beta version of ask_pipeworx and a universal router with the same tools, arguments, and response shape, which is specific enough. It distinguishes it from the stable ask_pipeworx by the experimental routing edge, though it does not explicitly contrast it with ask_pipeworx_grounded.

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 states that results are compared against the stable router. This is clear context, though it does not explicitly state when NOT to use it or mention the grounded sibling variant.

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