mcp_opendaw_list_transient_markers

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

The description is consistent with the readOnlyHint annotation, stating it lists markers. It adds value by describing the return format ('array of transient positions (in samples) or empty if none'), providing behavioral insight beyond the annotation alone.

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 with only three sentences plus a parameter explanation. It is front-loaded with the purpose, contains no redundant information, and every sentence adds value.

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 that an output schema exists, the description adequately covers purpose, parameter meaning, and output format. It mentions the possibility of an empty return. However, it does not address prerequisites like ensuring the region exists, and the sample unit could be clarified.

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, so the description must compensate. It explains that 'unit_index/track_index/region_index: Audio region coordinates,' adding meaning to the parameters. However, it does not specify valid ranges or how to obtain these indices, leaving some 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 verb 'List' and the resource 'transient markers for an audio region's audio file'. It explains what transient markers are (auto-detected hit points) and provides use cases (beat slicing, groove extraction), effectively distinguishing this tool from general list_markers tool.

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 mentions the tool is 'Useful for beat slicing and groove extraction,' which implies when to use it. However, it does not explicitly state when not to use it or provide direct alternatives among siblings. The context is clear but lacks explicit exclusions.

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