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

Beyond the annotations declaring it read-only, open-world, and idempotent, the description discloses real behavioral traits: it routes to one of 5,743 tools, fills arguments, returns stable pipeworx:// citation URIs, and is a single fast call. There is no contradiction with 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 long but densely informative, with the core instruction front-loaded and every section contributing either scope, examples, or escalation logic. It could be slightly trimmed, but it is not padded.

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 broad default entry point with no output schema, the description covers scope, input style, expected return shape (structured data with citation URIs), performance, tier availability, and relationships to alternatives. Nothing an agent needs to decide whether and how to call this tool 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?

The input schema fully documents the one required string parameter and its aliases, so the baseline is 3. The description adds value by providing concrete example questions and trigger phrasing patterns that clarify what makes a good natural-language query.

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 a specific purpose: route factual questions about real-world data to Pipeworx's tool set and return a structured answer with citations. It also differentiates itself from Web search and from siblings like ask_pipeworx_grounded and deep_research, so an agent can tell what this tool is for.

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 explicit when-to-use guidance, including trigger phrases ('what is', 'look up', 'get the latest'), says to prefer it over Web search, and names when to escalate to ask_pipeworx_grounded or deep_research. This is unusually complete routing guidance.

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