mcp_opendaw_get_midi_effect_chain

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

Annotations already declare readOnlyHint=true, confirming the tool is read-only. The description adds value by detailing the output: 'ordered list of MIDI effects with type, enabled state, and index', which goes beyond the structured annotation. No contradictions.

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: two sentences for purpose and a single line for the parameter. Every word is necessary, no redundancy, and it is front-loaded with the core action.

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?

The tool is simple with one parameter and an output schema exists. The description covers the return content and parameter meaning. It lacks notes on edge cases (empty chain, invalid index), but given the output schema, it is sufficiently complete for an AI agent to use correctly.

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?

The input schema has 0% description coverage, but the description explains 'unit_index: Audio unit index.' This adds essential context beyond the schema's type-only definition, effectively compensating for the lack of schema descriptions.

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 verb 'Get', the resource 'MIDI effect chain', and the context 'for an audio unit'. It distinguishes from siblings like 'get_effect_chain' by specifying 'MIDI', making the purpose precise and unambiguous.

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 does not explicitly guide when to use this tool versus alternatives such as 'list_midi_effects' or 'get_effect_chain'. While the name and context imply usage for a specific audio unit's MIDI effects, there is no when-not or comparison to siblings.

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