set_crestron_devices

Apply a scene or macro by setting multiple Crestron devices in one call, with optional analog fade and delay timing for staged sequences.

Instructions

Apply a scene/macro: set many devices in one call. Each entry can optionally fade (duration_ms, analog only - the device ramps to value instead of snapping) and/or start after a wait (delay_ms). Use for "movie night" (fade lights down over 2s + lower screen + projector on) or staged sequences. Values follow control_crestron_device rules (digital/analog/serial). A plain (no-timing) value may contain colons but not commas.

Behavior4/5

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

No annotations are provided, so the description carries full burden. It discloses that fading (duration_ms) is analog-only, that delay_ms can be applied, and that plain values may contain colons but not commas. It does not mention idempotency, authorization requirements, or side effects, but the core behavior is well-covered.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Every sentence adds value. The description is concise yet informative, front-loading the purpose and providing examples. No redundant phrasing or unnecessary details.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no annotations, no output schema, and one parameter, the description is remarkably complete. It covers purpose, usage context, parameter constraints, behavior nuances, and examples. The sibling list further aids context. There are no obvious gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description adds meaning beyond schema: it explains analog-only restriction for duration_ms, the comma/colon constraint for values, and the relationship to control_crestron_device rules. These details help the agent use parameters correctly.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool applies a scene/macro by setting many devices in one call. It provides specific examples ('movie night', staged sequences) and the verb 'set' combined with 'many devices' distinguishes it from siblings like control_crestron_device (single device) and pulse_crestron_device.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly says when to use this tool (e.g., 'movie night' or staged sequences) and implies when not to use (if only setting one device, use control_crestron_device). It also references 'Values follow control_crestron_device rules' to guide value formatting. However, it does not explicitly list alternatives or state when to avoid this tool.

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