Create DMX fixture pipeline

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

Annotations indicate mutation (readOnlyHint=false) and open-world (openWorldHint=true). The description adds significant behavioral context: it creates multiple CHOPs, inserts pads, merges, and drives dmxoutCHOP. It also states the return (container + JSON report) and what is not auto-exposed. No contradictions with 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 moderately long but well-structured: starts with purpose, then step-by-step mechanics, and ends with return info and a usage tip. Every sentence contributes value, though some redundancy exists (e.g., 'Constant CHOP' repeated). It is front-loaded and clear, but not extremely concise.

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?

Given the high schema coverage, annotations, and sibling tools, the description covers the tool's behavior, returns, and limitations. It mentions warnings and return report. It could elaborate on prerequisites (e.g., network interface for dmxout) or error handling, but overall comprehensive for a creation tool.

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% with parameter descriptions. The description does not add new information about each parameter beyond what the schema provides (e.g., 'Base name for the container COMP' already in schema). However, the overall narrative helps understand parameter roles in the pipeline. At high coverage, baseline 3 is appropriate.

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 uses specific verbs and resources: 'Build a DMX/Art-Net output chain from a fixture list.' It details the process (creates Constant CHOPs, pads, merges, drives dmxoutCHOP) and distinguishes this tool from siblings by clearly outlining its unique pipeline construction. The tool name already hints at DMX fixture focus, and the description solidifies it.

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 implies when to use this tool (to build a DMX pipeline from fixture list) and provides useful guidance on what not to expect: 'Per-fixture sliders are NOT auto-exposed — bind individual channels later with bind_to_channel / animate_parameter.' This tells users they need additional steps, but it does not explicitly exclude scenarios or mention alternative tools. The context is clear but lacks explicit when-not-to-use.

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