mcp_opendaw_get_signature_events

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

The annotation readOnlyHint already signals a safe read operation. The description adds value by clarifying the default base signature (4/4) and the detail that PPQN positions are accumulated, which gives the caller insight into the data structure beyond the annotation.

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 and front-loaded with the main purpose. Minor redundancy exists with two sentences both starting 'Returns', but the overall structure is efficient and easy to parse.

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 zero-parameter read-only listing tool with an output schema, the description is fully complete. It explains the return structure including the base signature and the event fields (index, position, bars, nominator/denominator), providing the agent all necessary context to call and interpret the tool 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?

There are no parameters, so there is no parameter detail to add. The description appropriately focuses on return value semantics, which is sufficient since the schema has zero parameters and no ambiguity.

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 tool lists all time signature change events and specifies the returned base signature and event fields. It is a specific verb+resource, though it does not explicitly distinguish itself from the sibling tool mcp_opendaw_list_signature_changes.

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 use when you need time signature information from the project, but it does not provide explicit when-to-use or when-not-to-use guidance, nor does it reference alternatives. Given there are related tools like list_signature_changes, more direct comparison would have improved this score.

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