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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, covering the safety profile. The description adds valuable behavioral context: it is a beta with candidate routing improvements, currently matches stable exactly, and is a full working router rather than a stub. This goes beyond the annotations.

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 slightly lengthy but front-loaded with the key fact that it's a beta version of ask_pipeworx. Each sentence adds meaningful information about experimental status, current equivalence, and usage. It could be trimmed slightly but remains efficient for the complexity it conveys.

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 there is no output schema, the description compensates by stating the response shape is identical to ask_pipeworx, which an agent can reference. It covers the experimental nature, current state, and usage guidance. Combined with annotations and schema, nothing critical is missing for an agent to call it correctly.

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 schema has 100% coverage, describing the 'question' parameter and all aliases clearly. The description does not add any parameter-specific meaning, but since the schema already documents everything, the baseline of 3 is appropriate. No additional value is needed here.

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 this is the beta version of ask_pipeworx, an identical universal router with the same tools, arguments, and response shape. It explicitly distinguishes itself from the stable ask_pipeworx by being the experimental edge, so an agent can tell it apart from the sibling tool without ambiguity.

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 says 'Use it exactly like ask_pipeworx when you want the newest routing', which gives a clear usage condition. It also notes that results are compared against the stable router to decide merges, implying it's for experimental evaluation. However, it does not explicitly state when NOT to use it (e.g., for stability-critical tasks), leaving some room for inference.

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