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

Annotations already establish read-only, open-world, idempotent behavior; the description adds useful operational context: it routes across 5,743 tools, fills arguments automatically, and returns structured answers with stable pipeworx:// citation URIs. This goes beyond the annotations without contradicting them, though it does not disclose any failure modes or limits.

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 verbose and repetitive: the example list appears twice, and the final sentence about breaking-news packs is garbled and redundant. The useful guidance is front-loaded, but the duplicated examples and trailing malformed phrase make it longer and harder to scan than necessary.

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 complex routing tool with no output schema, the description covers what the tool does, when to use it, example inputs, and what the answer looks like (structured answer with stable pipeworx:// citation URIs). It is incomplete only in that it does not explain how this tool differs from its beta or grounded siblings or what happens when the routing fails.

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 six parameters are documented aliases for the core 'question' parameter, so the schema already explains the input surface. The description adds meaningful guidance by listing trigger phrases, example questions, and the kinds of real-world factual requests that should be passed in, which helps an agent formulate the parameter 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 clearly identifies the tool as a natural-language question router that returns structured answers with citation URIs, so an agent knows what it does. However, it never differentiates this version from its siblings ask_pipeworx_beta and ask_pipeworx_grounded, so siblings could be selected incorrectly.

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, detailed when-to-use guidance: prefer over web search, use for listed data domains, use on trigger phrases such as "what is" and "look up", and start here for most questions. It does not, however, provide when-not-to-use guidance or point to sibling alternatives, so exclusions are missing.

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