mcp_opendaw_get_region_play_mode

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

Annotations already mark this as read-only. The description adds that it returns play mode details or info for plain playback, which provides some behavioral context beyond the annotation. However, it lacks details on potential error conditions or index conventions.

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 two sentences plus parameter annotations—no filler, front-loaded with the main purpose. Every word 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 existence of an output schema, the description sufficiently covers the tool's function: it identifies the resource, explains parameters, and notes the fallback case. Minor missing detail: index starting point (0 or 1) is not stated.

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?

With 0% schema description coverage, the description provides basic parameter explanations (unit_index: AU index, etc.), adding meaning beyond bare property names. However, this is minimal and could be more detailed (e.g., index ranges or valid values).

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 tool retrieves the play mode of an audio region, listing specific attributes (stretch type, playback rate, cents, transient mode). This verb+resource pattern distinguishes it from sibling tools like get_region_info.

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?

No guidance on when to use this tool versus alternatives (e.g., get_region_info or other region-related tools). No prerequisites or context provided.

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