mcp_opendaw_set_audio_region_waveform_offset

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

No annotations are provided, so the description carries the full burden. It discloses that the tool modifies the visual offset and returns old and new values. However, it does not detail side effects, permissions, or whether the change is reversible. The behavioral impact is moderately transparent.

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 extremely concise with no fluff: 6 lines covering purpose, parameter list, and return value. Every sentence adds value, with clear grouping and no redundancy.

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 existence of an output schema and the tool's simplicity, the description adequately explains the set operation, parameter roles, and return value. It does not explain the hierarchy (unit->track->region) but this is inferable from parameter names. It is mostly complete for a straightforward setter.

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 the description must compensate. It lists parameters with brief labels ('AU index', 'Offset value in seconds') but lacks constraints, ranges, or relationships. This adds basic meaning beyond the schema's titles but is insufficient for precise invocation.

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 action: 'Set the waveform display offset of an audio region'. It explains the purpose: 'shifts the visual start of the waveform' and distinguishes itself from sibling tools like set_audio_region_fade or set_audio_region_gain by focusing on waveform offset.

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?

The description provides an implied usage context ('useful for aligning the waveform display with the actual audio content'), but lacks explicit guidance on when to use this tool versus alternatives or when not to use it. No exclusions or comparisons to sibling tools are given.

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