mcp_opendaw_set_tidal_rate

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

With no annotations, the description bears full burden for behavioral context. It only states the action ('set') and valid rate values, but omits side effects, permissions, error conditions, or what happens with invalid indices.

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?

One sentence plus a bullet list; no waste. Front-loads the purpose and then details parameters concisely.

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?

Covers input parameters well but lacks output behavior, error handling, and side effects. With no annotations, more behavioral context would be needed for completeness. Output schema exists but is not provided.

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?

Despite 0% schema coverage, description adds meaningful context: clarifies unit_index, effect_index (must be Tidal), and lists all valid rate strings. Supplements the bare schema effectively.

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?

Clearly states the action (set), resource (LFO rate on a Tidal effect), and method (using a musical fraction string). Distinct from siblings by specifying a particular effect parameter.

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, no prerequisites mentioned (e.g., effect must be Tidal, indices must exist), and no comparison to other setter tools.

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