mcp_opendaw_create_mute_automation

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

With no annotations, the description carries full burden. It explains the event format, includes examples, and notes return values (events created, mute schedule, track index). However, it does not disclose whether existing automation is overwritten, error behavior, or any destructive side effects—important for a write tool.

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 well-organized: purpose statement, usage rationale, parameter explanations, return info, and two worked examples. Every sentence adds value, and it remains readable despite length. Front-loaded with the main purpose.

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 moderate complexity (2 params, nested data as string) and presence of an output schema, the description provides sufficient context: input format, examples, expected outcomes, and return summary. It covers the tool's role without needing to detail output fields since an output schema is available.

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 fully compensates. It explains unit_index as 'AU index to automate mute on' and provides a detailed interpretation of events with a JSON array format, beat semantics, muted meaning, and a concrete example. This goes far beyond the bare 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?

The description clearly states 'Create timed mute/unmute automation events on an audio unit' with a specific verb and resource. It distinguishes from siblings by explicitly stating it 'Replaces multiple set_track_mute calls with one automation track,' setting it apart from other automation tools.

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 clear usage context ('Essential for section dynamics: mute drums during breakdowns, unmute for drops, create structural silences') and mentions an alternative (set_track_mute). However, it does not explicitly exclude scenarios or compare with other automation-related siblings like create_automation_event or add_automation.

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