mcp_opendaw_set_region_loop

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

No annotations provided, so description carries full burden. Explains basic effect (looping, disable with 0) but omits side effects, error conditions, or destructiveness. Adequate but not comprehensive.

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?

Concise, with a clear logical flow: purpose, concept explanation, then parameter list. No wasted words, though more structured formatting could improve scannability.

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?

Output schema exists, so return values are covered. Lacks information on prerequisites (e.g., region must exist), error handling, or success criteria. Adequate for typical use but incomplete for edge cases.

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?

All 6 parameters are explained with clear examples and constraints (e.g., loop_beats = 0 disables loop, unit_index = -1 searches all AUs). Since schema descriptions are absent, this fully compensates.

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?

Clearly states 'Set loop parameters for a note region', distinguishing it from the sibling 'set_loop_region' which likely handles global project loops. The verb+resource is specific.

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?

Provides context on looping behavior but lacks explicit when-to-use or when-not-to-use compared to siblings like 'set_loop_region'. No guidance on prerequisites or alternatives.

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