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

Beyond the annotations (readOnly, openWorld, idempotent, non-destructive), the description discloses critical behavioral traits: it may have candidate routing improvements enabled live, the current state has no active candidate and matches ask_pipeworx exactly, and it is a full working router with no fallback. This transparency about variable behavior over time exceeds what annotations convey and directly informs invocation.

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 concise and front-loaded, leading with the core identity (beta version of ask_pipeworx, identical router) and moving through status, usage, and safety. It is information-dense with minimal redundancy, though the final sentence ('Falls back to nothing...') could be seen as a slightly repetitive reassurance given the earlier claim of being a full working router.

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 description covers what the tool is, its current behavior, when to use it, and its relationship to the stable counterpart. Given the rich annotations and high schema coverage, the only missing element is an explicit statement of return value, but no output schema exists and the description already establishes 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?

The input schema provides 100% coverage: every parameter is described, including the main 'question' field and all five aliases (q, text, input, query, prompt). The description adds no extra parameter semantics beyond referencing 'same arguments' as ask_pipeworx, so it correctly stays at the baseline for high schema coverage.

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 version of ask_pipeworx, an identical universal router with a specific scope (5,743 tools, same arguments and response shape). It distinguishes it from the stable sibling ask_pipeworx and notes the experimental nature. However, it relies on the reader already knowing what ask_pipeworx does; the core action (routing a question to the appropriate tool) is implied rather than directly stated.

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 wanting the newest routing, and clarifies that results are compared against the stable router. It names the alternative (ask_pipeworx) and provides the key condition of wanting experimental routing. It does not mention grounded or other alternative siblings, but the provided guidance is actionable and sufficient.

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