mcp_opendaw_set_marker_repeat

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

With no annotations, the description carries the behavioral disclosure burden. It adds useful semantics by explaining that repeat_count 0 means infinite repeat and 1-16 means N repeats, but it does not mention side effects, error behavior, or reversibility of the operation.

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: one purpose line and two parameter lines, with no filler. Every sentence earns its place, and the most important information is front-loaded.

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?

For a simple two-parameter setter with an output schema, the description covers the operation, parameter semantics, and the prerequisite of list_markers. It lacks mention of error conditions for invalid markers, but overall it is sufficiently complete for its complexity.

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%, but the description fully compensates by explaining both parameters: marker_index is the 0-based index from list_markers, and repeat_count has a clear value range and meaning. This goes well beyond the bare integer type definitions in 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 'Set the repeat count on a timeline marker', using a specific verb and resource. It distinguishes itself from sibling marker tools like set_marker_position, set_marker_label, and delete_marker by focusing on the repeat count property.

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 by specifying that marker_index comes from list_markers and is 0-based, implying the prerequisite of listing markers first. It does not explicitly discuss alternatives or when not to use the tool, but the context is sufficient for a simple setter.

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