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

The description adds substantial behavioral context beyond the annotations: it is a live experimental edge, candidate routing improvements may be enabled at any time, no candidate is currently active, and it falls back to nothing because it is a full working router. This discloses the beta risk and current equivalence without contradicting the read-only, idempotent, non-destructive 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 somewhat wordy with redundant emphasis on full functionality, but it is well-structured and front-loaded: definition, current status, usage instruction, and reassurance. Each sentence contributes meaningful context for a beta tool, though some compression is possible.

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 tool that is intentionally identical to ask_pipeworx, the description provides everything an agent needs: what it is, current behavior, when to use it, how it relates to the stable router, and its experimental nature. The lack of an output schema is mitigated by the explicit statement that the response shape matches ask_pipeworx.

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%, with the schema already documenting the 'question' parameter and all aliases. The description adds no new parameter-level detail beyond stating that arguments match ask_pipeworx. Per the baseline rule for high schema coverage, this is adequate but not enhanced.

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 version of ask_pipeworx, a universal router with identical tools, arguments, and response shape. It distinguishes itself from the stable sibling tool by emphasizing the experimental routing candidates and current equivalence. The verb 'ask' and resource 'pipeworx' plus the explicit comparison to ask_pipeworx make the purpose unambiguous.

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 agent wants the newest routing, and it explains that results are compared against the stable router to decide merges. It also clarifies the current state: no candidate is active, so behavior currently matches ask_pipeworx. This is clear when-and-alternative guidance.

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