mcp_opendaw_create_song_structure

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

No annotations are provided, so the description carries full burden. It correctly states it creates labeled markers and reduces calls, but does not disclose potential side effects (e.g., overwriting existing markers at the same positions) or required permissions. The behavioral details are adequate but not comprehensive.

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 concise, with a clear first sentence stating purpose. It uses structured paragraphs and includes an example. However, the example could be integrated more cleanly, and the description is slightly verbose with 'enabling agents to reason about song form' which is somewhat redundant. Overall well-structured.

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?

With an output schema (context signal), the description only needs to note return values, which it does ('Returns created markers with positions and total duration'). It covers both parameters adequately. Missing edge cases or error handling, but given the tool's simplicity, it is sufficiently complete.

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%, so the description compensates well. It explains the 'sections' parameter format (JSON array with name and bars), default bar value (8), and notes names become labels. It also clarifies 'unit_index' as unused but kept for API consistency, which adds meaning 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?

The description clearly states the verb 'Create' and the resource 'song structure markers for arrangement (intro/verse/chorus/bridge/outro)'. It distinguishes from siblings like mcp_opendaw_add_marker (single marker) and mcp_opendaw_analyze_song_structure (analysis), making the purpose 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?

The description implies usage by stating 'Reduces 5-10 marker calls to one structured call', guiding agents to use this instead of calling add_marker multiple times. However, it lacks explicit conditions for when not to use it (e.g., for single markers). The sibling mcp_opendaw_add_marker exists, creating a clear contrast.

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