create_midi_region

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

With no annotations, the description carries full burden but only states the basic purpose. It does not disclose side effects (e.g., file creation), requirements (e.g., Logic availability), or any constraints. The output schema exists but behavioral traits like mutation or idempotency are omitted.

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 a single sentence, which is concise, but it lacks structure or front-loading of critical details. Every word earns its place, but the content is insufficient for the tool's complexity.

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 7 parameters, no annotations, and no param descriptions, the description is highly incomplete. It does not cover workflow, output format, or environmental requirements. The output schema partially mitigates return value ambiguity, but behavioral context remains 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?

Schema description coverage is 0%, and the description adds no information about any of the 7 parameters (e.g., prompt, bpm, key). It fails to explain their meaning, defaults, or how they affect output, requiring the agent to guess.

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's purpose: creating a Logic-importable MIDI region from a short musical prompt. It uses a specific verb and resource, but does not explicitly distinguish from sibling tools like create_chord_region or create_drum_region, which limits the score.

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 provided on when to use this tool versus alternatives (e.g., create_chord_region, create_drum_region). There is no mention of prerequisites, context, or exclusion criteria, leaving the agent to infer usage.

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