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

The annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, but the description adds meaningful operational context: candidate routing improvements are live only when under test, results are compared to the stable router, and this is a full working router rather than a fallback stub.

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?

Three dense, purposeful sentences front-load the identity and key distinction, then explain usage and operational state. Every sentence earns its place with no filler or repetition.

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 beta variant of an existing tool, the description fully covers what it shares with the stable version, when to use it, its current behavior, and why it exists. Stating that the response shape is identical compensates for the missing output schema.

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%, so the baseline is 3. The description refers to 'same arguments' as ask_pipeworx but does not elaborate on the question parameter, aliases, or usage semantics beyond that pointer.

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 opens by defining the tool as 'Beta version of ask_pipeworx' and explicitly says it is a universal router with the same 5,798 tools, arguments, and response shape. It clearly separates this experimental variant from the stable ask_pipeworx and from other siblings.

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 gives an explicit usage instruction: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also names the stable alternative and clarifies the current state, noting no candidate is active so it matches ask_pipeworx exactly right now.

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