mcp_opendaw_set_studio_setting

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

No annotations are provided, so the description carries the full burden. It discloses value formats ('true'/'false' for booleans, strings for enums) and lists example settings, but it does not mention persistence, immediate application, validation behavior, or error handling. This is useful context but not complete transparency.

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: one clear purpose sentence, an Args block, and a Common settings list. It is longer than minimal but every section provides operational value. The category list is partly redundant with the common-settings dotted keys, but not severely bloated.

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 3-parameter tool with no schema descriptions and no annotations, the description is quite complete. It covers all categories, value representations, and a substantial set of common settings. It lacks explicit return-value/error behavior and a way to discover all keys, but the output schema existence reduces the need to describe return values.

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. It explains allowed category values, gives key examples, describes the value parameter's encoding, and provides a common-settings table with types and enum options. This adds substantial meaning 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 opens with 'Set a studio preference setting,' which is a specific verb + resource statement. It clearly distinguishes this tool from sibling read/settings tools like mcp_opendaw_get_studio_settings and from per-track/effect setters by limiting scope to 'studio preference settings' and enumerating categories.

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 labeling the tool as a studio preference setter and listing categories/common settings, but it never explicitly states when to use it versus alternatives or when not to use it. It provides no exclusions or comparisons to sibling tools.

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