mcp_opendaw_set_audio_region_time_base

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

With no annotations provided, the description carries the full burden. It discloses that the tool controls duration interpretation, changes are reversible by re-setting, and it returns old and new time base. It adds valuable context beyond the schema.

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 structured with a purpose statement, then detailed explanation of time base modes, followed by parameter list. It is relatively concise with no redundant sentences, though it could be slightly more compact.

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 presence of an output schema (not shown) and the tool's straightforward nature, the description adequately covers purpose, parameters, return value, and semantics. It provides sufficient context for an agent to select and invoke the tool correctly without ambiguity.

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?

Schema description coverage is 0%, so the description fully compensates by providing clear, concise explanations for each parameter: unit_index, track_index, region_index, and time_base with valid values. This adds significant meaning beyond the bare schema.

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 'Set the time base of an audio region' with specific verb and resource. It explicitly explains the two options and their effects, making it highly distinguishable from sibling tools, many of which are other set_* operations.

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 explains when to use each time base value ('musical' vs 'seconds') with clear effects. However, it does not provide explicit guidance on when not to use this tool or mention alternatives, relying on implied usage from the parameter descriptions.

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