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

Beyond the readOnly/openWorld/idempotent annotations, the description reveals live candidate routing improvements, that none are active as of 2026-07-26, that it falls back to nothing, and that it is a fully working router rather than a stub. This is exceptionally candid about experimental behavior.

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?

Every sentence carries distinct information: beta relationship, candidate behavior, current no-active-candidate state, usage instruction, evaluation purpose, and fallback clarification. It is dense but not bloated, and key identity and usage details are front-loaded.

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 is largely complete for selecting and invoking the tool: it explains current behavior, exact parity with ask_pipeworx, and that it is a full router. However, it relies on ask_pipeworx's known behavior for response-shape details rather than describing the output itself, which is a minor gap given no output schema is present.

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%, so the schema already documents all six parameter aliases and the natural-language question input. The description adds no parameter-level meaning beyond noting 'same arguments' as ask_pipeworx, so the high-coverage baseline applies.

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?

Description clearly defines it as the beta version of ask_pipeworx, an identical universal router with the same 5,718 tools, arguments, and response shape. It explicitly distinguishes it from the stable sibling by labeling it the experimental edge.

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?

States when to use it: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also clarifies current status—no active candidate, so it matches ask_pipeworx exactly—and notes results are compared against the stable router to decide merges.

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