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

Annotations already cover read-only, idempotent, and non-destructive behavior. The description adds substantial context: candidate routing improvements may be live, no candidate is active as of 2026-07-26, so it currently matches ask_pipeworx exactly, and it is a full working router with no fallback. This temporal and experimental detail is genuinely useful beyond what annotations provide.

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 well-structured: it front-loads the beta relationship, then gives the current state, usage guidance, and a caveat against treating it as a fallback. Each sentence contributes meaning; there is only minor redundancy between 'currently matches ask_pipeworx exactly' and 'Falls back to nothing'.

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?

With full schema coverage and annotations covering safety and idempotency, the description is sufficient for correct invocation. It states how to use it, its current state, and that the response shape matches ask_pipeworx, which mitigates the lack of an output schema. Nothing about selection or invocation is missing.

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?

The input schema already documents all six parameters with 100% coverage, including the note that question accepts aliases. The tool description only says 'same arguments' without adding any parameter-specific semantics, so it adds no value 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 states it is the beta version of ask_pipeworx, an identical universal router with the same 5,798 tools, arguments, and response shape. This clearly positions it as an experimental routing tool for user questions, though the exact function still relies on knowing what ask_pipeworx does. It differentiates from the stable ask_pipeworx sibling by being 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?

It explicitly instructs to use it exactly like ask_pipeworx when the newest routing is desired and notes results are compared against the stable router to decide merges. The 'experimental edge' language implies it is not for stable/production use, though no alternative beyond ask_pipeworx is explicitly named.

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