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

The description reveals non-obvious behavioral details beyond the annotations: it is an experimental edge, candidate routing improvements may be active, none are active as of the stated date, it currently matches ask_pipeworx exactly, and it has no fallback because it is a full working router. These details meaningfully help an agent understand what to expect from the 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 front-loaded with the core identity and current state, and each sentence contributes useful information. The parenthetical retirement date is mildly extraneous, but overall the length is justified by the need to convey beta candidacy, current status, and the absence of a fallback.

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 beta alias of an existing tool, the description provides enough orientation: it names the stable counterpart, states the interface is identical, and explains the experimental nature and current parity. The lack of an absolute response-shape description is a minor gap, but the explicit reference to ask_pipeworx covers most of the missing practical 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 description coverage is 100%, and the schema itself documents all six parameters as aliases for the question field. The description adds only the relational claim that arguments are identical to ask_pipeworx, which is useful but does not substantially augment the schema's already complete parameter semantics.

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 opens by identifying the tool as a beta version of ask_pipeworx and explicitly calls it an identical universal router with the same 5,743 tools, arguments, and response shape. This clearly distinguishes it from the stable ask_pipeworx sibling and states its scope and function without being a tautology.

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 an explicit usage cue: '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, providing context for when the beta version is intended. It does not enumerate exclusions or compare against other sibling tools like ask_pipeworx_grounded, but the guidance is sufficient for routing decisions.

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