mcp_opendaw_create_section_transition

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

With no annotations, the description carries the transparency burden. It discloses what the tool does (filter sweeps, volume fades, mute automation, impacts) and details the exact behavior per preset (e.g., 'filter close on synths, drums muted, then filter open + unmute + impact'). It also states the return value ('Returns summary of all automation created across units'). Missing is whether existing automation is overwritten or if any prerequisites exist, but overall it paints a clear behavioral picture.

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-structured with a high-level summary, a 'why use' statement, parameter details, and examples. No sentence is wasted; the formatting with arrows and line breaks makes the preset definitions scannable. It's longer than average, but every element adds value.

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 tool's complexity (4 params, multiple automation behaviors) and lack of annotations, the description is quite complete. It covers all presets, timing parameters, unit index conventions, and provides examples. The output schema exists, so the description's note on the return value is sufficient. A minor gap is lack of info about how existing automation is handled, but this doesn't significantly detract.

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 description coverage is 0% and the description fully compensates. transition_type is enumerated with detailed meanings for each value. start_beat, duration_beats, and unit_indices all have clear definitions, defaults, and additional context (e.g., the unit index convention 'drums=0, bass=1, lead/synth=2, pads=3'). Examples demonstrate parameter usage concretely.

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 what the tool does: 'Create a complete section transition in one call' and explicitly contrasts it with individual automation tools ('Replaces 3-5 individual calls'). It identifies the specific resource (section transitions) and the verb (create), and distinguishes itself from related tools like create_filter_sweep and create_volume_fade by framing itself as a composite.

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 clear usage context: 'The most common arrangement technique: moving from one section to another' and implies when to use it over manual calls by saying it 'combines multiple automation tools' and 'Replaces 3-5 individual calls'. It doesn't state explicit when-not-to-use scenarios, but the guidance is strong and helps select this tool over alternatives.

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