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

The annotations already declare readOnly, openWorld, idempotent, and non-destructive behavior. The description adds useful behavioral context (routing, fast single call, returns citations), but does not detail failure modes or limits in depth. Given the annotation coverage, the description adds meaningful but not exhaustive transparency.

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, front-loading the core guidance and using examples and differentiation. Minor redundancy exists (e.g., repeating the source/tool counts and 'START HERE' emphasis), but it remains readable and purposeful.

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?

The description is complete for an agent: it covers what the tool does, when to use it, when not to use it, examples, default status, and relationships to sibling tools. No output schema exists, so no return-value documentation is required.

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?

The schema covers all six parameters and describes each alias as equivalent to 'question'; the description reinforces that the question is natural language. It does not add much beyond the schema, but the schema coverage is high and the semantics are clear.

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 states the tool's purpose: to answer factual/current-data questions by routing to authoritative sources. It explicitly differentiates from web search and names sibling alternatives (ask_pipeworx_grounded, deep_research), making its role unmistakable.

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 when-to-use guidance: prefer over web search for listed data domains, use as default entry point, and step up to alternatives only when specific needs arise. It also includes concrete examples and even addresses breaking-news scenarios.

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