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

Annotations already cover read-only, idempotent, and open-world hints, and the description adds valuable context: the beta status, the possibility of candidate improvements being active, and the clarification that it is a fully working router. It does not contradict annotations and explains the experimental edge, which is beyond what structured fields convey. No significant gaps.

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 informative and reasonably structured, starting with the beta label and then detailing current status and usage. It avoids excessive jargon, though phrases like 'Falls back to nothing' could be seen as slightly redundant. Overall, it is concise for the amount of context it conveys, with no wasted sentences.

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?

The tool has no output schema, so the description partially compensates by referencing 'same response shape' as ask_pipeworx, which is a sibling tool. This is acceptable if the agent has access to that definition, but the description does not fully self-contain the core routing behavior or return format. Given the complexity and reliance on sibling context, it is adequate but not fully 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 description coverage is 100%, and all parameters are aliases for 'question' with clear descriptions. The description mentions 'same arguments' but adds no extra semantic meaning beyond what the schema provides. With full coverage, the baseline of 3 is appropriate; no additional parameter insight is given.

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 the tool as a beta variant of ask_pipeworx, a universal router, and distinguishes it from the stable version by its experimental nature. It states it is 'identical' in functionality and scope, but does not explicitly define what the router does (e.g., routing questions to tools). This relies on prior knowledge of ask_pipeworx, making it somewhat dependent on sibling context, but still clear enough for differentiation.

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 'Use it exactly like ask_pipeworx when you want the newest routing,' providing a clear condition for selection. It also notes that current behavior matches the stable router and that results are compared for merging. However, it does not explicitly state when NOT to use it (e.g., for stable, non-experimental results) or mention alternatives like ask_pipeworx_grounded. This is adequate but lacks explicit exclusions.

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