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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint false o the safety profile is known. The description adds key behavioral context beyond annotations: it is the experimental edge, candidates may be live during test, no candidate is currently active, and it is a full working router with no fallback. This is rich transparency that informs invocation despite volatile routing 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 three sentences with no filler. It front-loads the core identity ('Beta version of ask_pipeworx'), then covers current state, usage condition, comparison purpose, and fallback behavior. Every sentence earns its place.

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 is complete for a routing variant. It anchors to ask_peworx for arguments and response shape, explains the experimental nature and current status, and clarifies it is a fully functional router. Annotations cover safety, and no output schema is needed because response shape is explicitly said to match ask_peworx.

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% and every parameter (question plus five aliases) is documented in the schema. The description only says 'same arguments' as ask_pipeworx, which does not add meaning beyond the schema. Baseline 3 applies because the schema does the heavy lifting.

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 states this is a beta version of ask_pipeworx, an identical universal router with the same 5,767 tools, arguments, and response shape. It distinguishes itself from the stable ask_pipeworx sibling by emphasizing it is the experimental edge, so an agent can tell them apart.

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 you want the newest routing, and notes results are compared against the stable router to decide merges. It does not state an explicit when-not-to-use case, but the 'when you want the newest routing' condition is clear enough for selection.

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