mcp_opendaw_set_region_position

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

No annotations provided, so the description carries full burden. It explains parameters but does not disclose side effects (e.g., overwriting previous position, potential conflicts with other regions), required permissions, or if the operation is undoable. The term 'move' implies mutation but lacks detail on what changes occur beyond position.

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 two-paragraph structure: purpose sentence followed by parameter explanations. Each parameter gets its own line with clear formatting. Could be slightly more terse, but overall efficient and well-organized.

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?

Covers all parameters and action. Output schema exists (not shown) so return values are not needed. Does not mention how to locate the region (e.g., needing prior list calls), but for a move operation this is acceptable. Minor gap: no explanation of what happens if the target position is occupied.

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?

Despite 0% schema description coverage, the description provides clear, actionable semantics for all 5 parameters: explains units for position_beats (e.g., '4.0 = start of bar 2'), enum values for region_type, and the meaning of unit_index (-1 = search all AUs). This adds significant value beyond the raw schema types.

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 the action 'Move a region to a new position on the timeline.' The verb 'move' and resource 'region' are explicit, and the description distinguishes this from sibling tools like 'move_region_to_track' or 'set_region_duration' by focusing on timeline positioning.

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 on when to use this tool versus alternatives like 'move_region_to_track' or 'set_region_duration'. Does not mention prerequisites (e.g., region must exist) or context (e.g., undo behavior). This lack of usage direction makes it harder for an agent to decide when to invoke this tool.

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