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

The description goes well beyond the annotations by disclosing that this is an experimental edge, that candidate routing improvements may be live, that no candidate is active currently, and that it is a fully functional router rather than a fallback stub. This gives the agent an accurate behavioral model even though annotations already indicate read-only, idempotent, 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 somewhat longer than a minimal definition, but every sentence contributes meaningful context: identity, current state, usage instruction, comparison rationale, and fallback reassurance. The key point about being a beta variant is front-loaded, and the experimental nature is made immediately clear.

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 an experimental router with no output schema, the description covers everything an agent needs: what the tool is, its current equivalence to ask_pipeworx, when to use it, and the fact that it is fully functional. The lack of explicit return-value documentation is mitigated by the statement that the response shape matches ask_pipeworx exactly.

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 description coverage is 100%, so the schema fully documents all six parameters and their aliases. The description only adds that arguments are identical to ask_pipeworx, which is useful context but does not compensate or add detail beyond the schema's already-complete parameter documentation.

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 this as a beta variant of ask_pipeworx, a universal router with the same 5,798 tools, arguments, and response shape. It distinguishes itself from the stable ask_pipeworx by its experimental routing improvements, so an agent can tell exactly what this tool is and how it relates to its siblings.

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 says to use it exactly like ask_pipeworx when the newest routing is desired, and explains that results are compared against the stable router. It implies the stable alternative exists for non-experimental use, though it does not explicitly state when NOT to use this beta version.

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