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

Beyond the readOnly/openWorld/idempotent/non-destructive annotations, the description discloses that candidate routing improvements may be live, that none is currently active, and that there is no fallback — it is a fully working router. This gives an agent a realistic model of the tool's experimental, mutable 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?

Four sentences each earn their place: version/equivalence, current candidate status, usage and comparison purpose, and the no-fallback clarification. Key facts are front-loaded and there is no wasted content.

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 beta router variant, the description covers what it is, whether it differs from stable right now, how to invoke it, and the response-shape guarantee. With read-only annotations and full schema coverage, nothing essential 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?

Schema coverage is 100%, including aliases, so the description does not need to explain parameters. It only says 'same arguments' as ask_pipeworx, which is a compatibility hint rather than new semantic detail.

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 identifies ask_pipeworx_beta as the experimental variant of ask_pipeworx, a universal router with the same tools, arguments, and response shape. It distinguishes itself from the stable ask_pipeworx sibling by its beta/candidate-routing purpose.

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 says to use it exactly like ask_pipeworx when the newest routing is desired, and states that results are compared against the stable router to decide merges. It also clarifies that with no active candidate it currently matches ask_pipeworx exactly, providing concrete selection guidance.

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