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

The description adds important behavioral context beyond the annotations, revealing that this is an experimental edge with candidate routing improvements that may be under test, and that no candidate is currently active. It clarifies that it is a full working router, which is useful given the beta label and the annotations already indicate read-only, idempotent, and non-destructive 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?

The description is unusually verbose, with six sentences and several redundancies (the same points about identical tools, arguments, and response shape are repeated). It is front-loaded with the purpose and usage, but the retirement date and the multiple restatements could be trimmed without losing 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 that the tool has no output schema, the description compensates by stating the response shape is the same as ask_pipeworx. However, an agent not already familiar with ask_pipeworx would need additional information about output or behavior, though the sibling list includes ask_pipeworx as a reference. This is decent but not complete.

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%, so the baseline is 3. The description does not add parameter-specific meaning beyond restating that the arguments identical to ask_pipeworx, which is redundant with the schema's own clear description of aliases.

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 that this is a beta version of ask_pipeworx and identifies it as an identical universal router with the same tools and arguments, distinguishing it from the stable ask_pipeworx. It is specific about the resource and conveys the experimental nature, though it does not overtly restate the routing action in verb form.

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 like ask_pipeworx when you want the newest routing and explains that results are compared against the stable router. This is clear contextual guidance, but it does not mention or exclude alternatives like ask_pipeworx_grounded or others, so it stops short of full when-not guidance.

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