load_device

Load an instrument, effect, kit, or preset onto a track via an exact browser path or query name. Call get_track_info afterward to get the new device index.

Instructions

Load an instrument, effect, kit or preset onto a track (appended to its chain). Give an exact browser path (from browse/search_browser) or a query name like 'Reverb', 'Drift', 'EQ Eight', '808 Core Kit'. Call get_track_info afterwards to get the new device's index.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A3.8/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses the append-to-chain semantics and the recommended follow-up call, but says nothing about permissions, what happens if both path and query are given, or error behavior for an invalid path.

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?

Three tight sentences, front-loaded with the action and placement behavior, then the two input strategies, then the follow-up step. No wasted text.

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

Completeness4/5

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

With no annotations and no output schema, the description still covers the mutation, the placement, the input source, and the post-call needed to find the new device index. Missing only edge-case behavior and documentation of kind/category.

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

Parameters3/5

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

Schema description coverage is 0%, so the description must compensate for all five parameters. It adds real meaning for path (source is browse/search_browser) and query (example values like 'Reverb', 'Drift'), but leaves kind and category — the latter an 11-value enum — completely unexplained.

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

Purpose4/5

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

States a specific verb (load) and resource (instrument/effect/kit/preset) plus the target (track) and the placement behavior (appended to its chain). This clearly distinguishes it from create_track, though it does not explicitly name sibling alternatives.

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?

Gives concrete guidance: supply an exact browser path obtained from browse/search_browser, or a query name, and call get_track_info afterward to resolve the new device's index. It lacks explicit when-not-to-use cases or precedence rules when both path and query are supplied.

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