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

Beyond the annotations, the description discloses that it is a beta router with potentially live-enabling candidate improvements, that no candidate is currently active (so it matches ask_pipeworx exactly), and that it 'Falls back to nothing.' This gives agents a clear operational model of how the tool behaves over time and under test, which annotations alone do not convey.

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 moderately long but front-loaded with the core identity and scope, followed by current status, usage instruction, and a clarification about fallback. Some redundancy exists (e.g., 'experimental edge' reiterates earlier beta framing), but every sentence carries distinct operational information.

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 complete for an agent to call the tool correctly: it explains the routing function, current parity with ask_pipeworx, the purpose of using this beta variant, what to expect in response shape, and that there is no degraded fallback. With no output schema, saying 'same response shape' suffices, and the simple question-based input is fully covered by the schema.

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 fully documents the 'question' parameter and its aliases. The description mentions 'same arguments' but adds no semantic detail about any parameter beyond what the schema already provides. This meets the baseline but does not exceed it.

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 explicitly as a 'universal router' with a specific resource scope: the same 5,743 tools, arguments, and response shape as ask_pipeworx. It clearly differentiates this beta variant from its siblings (ask_pipeworx and ask_pipeworx_grounded) by its candidate routing improvements and experimental status.

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 direct instruction: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also explains the evaluation context (results compared against the stable router to decide merges), which implies when not to use it (when you want stable behavior), and clarifies it is a full working router with no fallback.

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