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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior. The description adds valuable context about its beta status, that no candidate is currently active, and that it matches ask_pipeworx exactly at this time, which informs whether to trust it for production use.

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 somewhat long but well-structured: it leads with the key fact (beta, identical), then current state, usage, and a final clarification. Phrases like 'same 5,953 tools, same arguments, same response shape' are slightly repetitive but each sentence carries meaningful content without fluff.

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?

With only one required parameter and no output schema, the description covers all essential aspects: what it does, when to use it, its current behavioral equivalence, and that it is fully functional. It even specifies the number of tools available, making it comprehensive for an agent to decide whether to call it.

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 all parameters (question and aliases) are described in the schema. The description adds 'same arguments' as ask_pipeworx but does not provide additional parameter-specific meaning beyond the schema, so it meets the baseline without adding extra value.

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 it is a 'Beta version of ask_pipeworx: identical universal router' with the same tools, arguments, and response shape. It clearly distinguishes it from the stable sibling by calling it the 'experimental edge' and specifying it is a fully working router that currently matches ask_pipeworx exactly.

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?

Explicitly instructs to 'Use it exactly like ask_pipeworx when you want the newest routing' and mentions results are compared against the stable router. It also states 'Falls back to nothing' to clarify it is not a wrapper, and implies the alternative is the stable ask_pipeworx when stability is preferred.

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