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

Beyond the annotations (read-only, idempotent, non-destructive), the description reveals that candidate routing improvements are toggled live, that none is active right now, and that the last was retired on a specific date. It also clarifies that this is a full working router, not a fallback stub. This is exactly the behavioral context 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 four sentences are dense and front-loaded with the tool's identity and current state. Slight redundancy in 'identical...same...same' and 'use exactly like' costs a little, but each sentence contributes needed context.

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-required-parameter, read-only router, the description covers current behavior, usage route, and comparison purpose. The main gap is that 'same response shape' is not self-describing without ask_pipeworx, and there is no output schema, but an agent has enough to invoke it correctly.

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%: every parameter (question and five aliases) is described, with question explicitly listing accepted aliases. The description adds only that arguments match ask_pipeworx, which is consistent but does not deepen parameter understanding beyond the schema.

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 a beta/experimental variant of ask_pipeworx and specifies that it is the same universal router with the same 5,908 tools, arguments, and response shape. This clearly separates it from the stable ask_pipeworx sibling and from ask_pipeworx_grounded, though it relies on the reader knowing what ask_pipeworx does rather than stating a direct action verb.

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 the newest routing is desired, and explains that results are compared against the stable router to decide what merges. It also notes that no candidate is currently active, so behavior currently matches the stable router. It does not name explicit exclusions or alternatives, but the when-condition is clear.

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