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

Beyond the readOnly/idempotent/non-destructive annotations, the description discloses the experimental beta nature, that candidate routing improvements are enabled live, that no candidate is currently active, and that it is a full working router with no fallback. This gives agents a realistic sense of the tool's behavior and reliability without contradicting the 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 a compact paragraph of four sentences that front-loads the beta identity and key distinction. Each sentence adds value—scope, current state, usage, and assurance—though the enumeration of identical attributes is slightly redundant given the opening phrase.

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?

Given the annotations, full schema coverage, and clear reference to ask_pipeworx's known response shape, the description covers everything an agent needs: what this tool is, how it relates to the stable sibling, when to use it, and its current operational status. No critical information is missing.

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% for all six parameters, so the structured data already documents the aliases and semantics. The description adds only a compatibility statement ('same arguments') rather than new parameter meaning, matching the baseline expectation for full 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 opens with 'Beta version of ask_pipeworx' and immediately specifies the exact scope: a universal router with the same 5,908 tools, arguments, and response shape. It clearly differentiates itself from the stable ask_pipeworx by its experimental routing intent, which is the central distinguishing feature.

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 when-to-use condition: 'Use it exactly like ask_pipeworx when you want the newest routing.' It also implies the alternative—the stable ask_pipeworx—by describing results being compared against the stable router. However, it does not explicitly state when not to use it (e.g., when stability is preferred), leaving a small gap.

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