mcp_opendaw_create_track_region

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

No annotations provided, so description carries full burden. It discloses auto-detection of track type and returns error for audio tracks, but lacks details on side effects, permission requirements, or idempotency. A 3 is appropriate for moderate disclosure.

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?

Well-structured with clear sections and bullet points. Every sentence adds value; no fluff. Efficiently communicates essential information in a compact form.

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 core behaviors, parameter meanings, and return fields. Output schema exists, so return details are less critical. Could mention edge cases like invalid track index or overlapping regions, but overall adequate for agent use.

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 coverage is 0%, so description must explain all parameters. It does so comprehensively: unit_index with default value note, track_index, start_beat, duration_beats, name with auto-labeling, and hue with color range and auto setting. Adds significant value beyond the schema.

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 tool creates a region on any track (note or value), automatically detects track type, and distinguishes itself from place_audio_region for audio tracks. The description is specific and unambiguous.

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?

Explicitly states when to use this tool (note and value tracks) and when to use an alternative (place_audio_region for audio tracks). Provides clear guidance on auto-detection and error handling.

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