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

The description goes well beyond the annotations by disclosing that candidate routing improvements may be enabled live, that none is currently active, that the tool currently matches ask_pipeworx exactly, and that results are compared against the stable router. It also clarifies there is no degraded fallback and that this is a full working router, making runtime behavior highly transparent.

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 front-loaded with the core identity, then explains current behavior, usage, and reliability in a compact, well-structured way. Every sentence contributes useful information, including the status update about the last retired candidate and the reassurance that the tool is fully functional.

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 tool with no output schema, the description compensates by specifying that the response shape is identical to ask_pipeworx, which is critical for an agent to know what to expect. Combined with annotations covering safety and the description covering routing semantics, current state, and comparison purpose, nothing essential 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%, with all parameters being string aliases for the same question input, so the schema already carries the parameter semantics. The description adds the note that arguments are 'the same' as ask_pipeworx, which is useful context but does not meaningfully expand on what each parameter means beyond the schema.

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 identifies a specific tool: a beta variant of ask_pipeworx that is an identical universal router with the same 5,743 tools, arguments, and response shape. It explicitly distinguishes itself from the stable ask_pipeworx and notes its experimental edge, so an agent can tell it apart from siblings immediately.

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?

The description gives explicit usage context: use it exactly like ask_pipeworx when you want the newest routing, and it notes the current state has no active candidate so it matches ask_pipeworx exactly. It does not explicitly state 'use stable ask_pipeworx for production' as a when-not-to-use condition, but 'beta' and 'experimental edge' strongly imply that distinction.

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