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

Beyond the annotations, the description discloses meaningful behavior: identical routing surface (5,724 tools), candidate routing improvements toggled live, currently no active candidate with a retirement date, exact parity with ask_pipeworx right now, and no fallback — it is a fully functional router. This gives strong transparency about the experimental edge and current state.

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 information-dense with no filler. Front-loaded with the core identity, it then covers current state, usage directive, comparison behavior, and clarification that there is no fallback. Each sentence contributes distinct operational value.

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?

Given the tool's complexity as a universal router, the description is complete: relationship to stable ask_pipeworx, current candidate state, argument and response parity, comparison purpose, and fallback behavior are all addressed. The schema already covers the single required parameter and aliases, and no output schema is needed since response shape is stated as identical.

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%, with the required question parameter and five aliases all documented. The description adds no new parameter meaning beyond saying 'same arguments' as ask_pipeworx, so the schema carries the semantic burden.

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 states a specific role: a beta version of ask_pipeworx that behaves as an identical universal router with the same tools, arguments, and response shape. It explicitly differentiates itself from the stable ask_pipeworx while also noting it currently matches it exactly, so an agent can tell what this tool is for.

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 explicit usage direction: use it exactly like ask_pipeworx when the newest routing is desired, and notes results are compared against the stable router. It names the stable alternative, but it does not provide an explicit when-not-to-use condition or distinguish itself from other siblings like ask_pipeworx_grounded.

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