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

Annotations already mark it read-only and idempotent, and the description adds meaningful behavioral context: candidate routing improvements are only active during tests, none are currently active, and it currently matches ask_pipeworx exactly. It also clarifies it is a full working router and does not fall back to anything, which prevents a serious misinterpretation.

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 information-dense and every sentence earns its place: identity, current experimental status, usage instruction, and a clarification about fallback behavior. It front-loads the key fact that this is the beta variant of ask_pipeworx.

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 universal router, the description covers identity, current behavior, and invocation equivalence well. It says the response shape is identical to ask_pipeworx but does not detail that shape; since there is no output schema, a bit more explicit return-value detail would make it fully self-contained. Still, the reference to ask_pipeworx provides enough grounding.

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 aliases and the natural-language question parameter are already fully documented. The description adds only the generic claim of 'same arguments' without new per-parameter meaning, which is acceptable given the schema already carries the 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 identifies a specific resource: a beta variant of ask_pipeworx that routes natural-language questions to the same 6,332 tools. It distinguishes itself from the stable router by its experimental routing improvements and current live-candidate status. This is far more specific than the title alone.

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 agent wants the newest routing, which gives a clear usage context. It does not explicitly name ask_pipeworx_grounded or state when not to use this tool, but the stable-versus-experimental framing makes the intended selection clear.

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