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

Annotations already cover read-only, open-world, idempotent, and non-destructive hints. The description adds valuable behavioral context: it is a live beta, candidate improvements may be active, nothing is active right now, and it is a full working router with no fallback. This goes well beyond the annotations without contradicting them.

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 four sentences and reasonably compact. It front-loads the identity and relationship to ask_pipeworx, then covers current state, usage, and no-fallback behavior. There is slight redundancy between 'identical' and 'currently matches ask_pipeworx exactly,' but it is not bloated.

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 simple alias-based tool with one required concept and full schema coverage, the description covers what it is, when to use it, its current state, and its relationship to the stable router. It is complete enough for an agent to safely select and invoke it, though more detail about what 'routing' produces would help.

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 all six parameters described as aliases for 'question'. The description adds only that the arguments are the same as ask_pipeworx, which is marginally useful but not parameter-specific. The schema is doing the heavy lifting here.

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 states this is a beta version of ask_pipeworx, an identical universal router with the same tools, arguments, and response shape. It differentiates itself from the stable sibling by being the experimental edge with candidate routing improvements. The purpose is clear, though it relies on the reader knowing what ask_pipeworx is.

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 mentions results are compared against the stable router. This gives a clear usage condition, though it does not spell out an explicit 'use the stable version when you need proven behavior' exclusion.

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