mcp_opendaw_connect_modular_modules

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

No annotations are provided, so the description must disclose behavioral traits. It only says 'Returns success or error.' It does not mention whether connections are overwritten, if multiple connections are allowed, or any side effects (e.g., cable routing conflicts). This is insufficient for a mutation tool.

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: one sentence for the purpose, followed by a bullet list of parameters, and a note on return value. It is front-loaded and easy to scan, though the parameter list could be more structured (e.g., grouping source vs target).

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 complexity of modular devices (multiple modules, output/input connectors), the description lacks essential context: how to obtain module indices, what connector names are valid, and whether `list_modular_modules` should be called first. The presence of an output schema does not compensate for this missing context.

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 coverage, the description must compensate. It lists parameters with one-line descriptions (e.g., 'Audio unit index', 'Effect index within the AU'), which add minimal context beyond the parameter names. It does not explain how to find valid module indices or connector names, nor does it provide example values or constraints.

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 action: 'Connect two modules in a Modular device (create a patch cable).' This provides a specific verb ('connect') and resource ('modules in a Modular device'), and it distinguishes this tool from siblings like `add_modular_module` or `remove_modular_module`.

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 is given on when to use this tool versus alternatives, prerequisites (e.g., modules must exist), or when not to use it (e.g., if a connection already exists). The description lacks any contextual usage instructions.

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