load_instrument_or_effect

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

The description does not disclose behavioral traits such as whether loading replaces existing devices, requires an empty track, or is destructive. With no annotations provided, the description carries the full burden for safety and side-effect disclosure, which it fails to meet.

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 succinct: two sentences and a parameter list with examples. Every piece of text adds value without redundancy. Well-structured and front-loaded.

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 tool is a mutation (loading) with no output schema and two simple parameters, the description is minimally adequate. However, it lacks contextual completeness about what happens upon load (e.g., overwriting, error conditions) and does not fully compensate for missing behavioral transparency.

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 description adds meaning beyond the schema by explaining 'track_index' as the track index and providing a concrete URI example. Since schema description coverage is 0%, this compensation is valuable. However, it could further detail valid URI formats or constraints.

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 loads an 'instrument or effect' onto a track using a URI, with an example URI provided. While the purpose is specific and actionable, it does not explicitly differentiate from sibling tools like 'load_drum_kit' or 'load_item_to_track', which could have overlapping functionality.

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?

No guidance is given on when to use this tool versus alternatives (e.g., load_drum_kit for drum kits, load_item_to_track for generic items). The description lacks any usage context, prerequisites, or scenarios, leaving the agent without decision-making support.

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