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

Beyond the read-only, idempotent, open-world annotations, the description discloses the live beta behavior, that no candidate is currently active, that results are used for comparison, and that the tool is a fully working router rather than a fallback. This directly addresses likely agent misconceptions and provides valuable behavioral context.

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 packs relevant details like candidate status, comparison behavior, and fallback clarifications. Minor redundancy appears in repeating that it currently matches ask_pipeworx exactly, but overall the length is justified by the beta-vs-stable distinction.

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 tool that is a live experimental variant of a large router, the description covers what it is, what is currently active, how to use it, what results are used for, and that it does not fall back to another implementation. With no output schema, the note that the response shape matches ask_pipeworx fills the main remaining gap.

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 at 100% coverage, including the aliases for `question`. The description adds that the tool accepts 'the same arguments' as ask_pipeworx but does not add further semantic meaning, so the baseline score of 3 is appropriate.

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 clearly states what ask_pipeworx_beta is: a beta version of ask_pipeworx with identical routing behavior, tool count, arguments, and response shape. It also explains the current experimental state (no candidate active), making its purpose and relation to the stable tool unmistakable.

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 explicitly tells the agent to use it exactly like ask_pipeworx when the newest routing is desired, and mentions that results are compared against the stable router. It does not contrast ask_pipeworx_grounded or give explicit when-not-to-use criteria, but the guidance is clear enough for selecting between the beta and stable variants.

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