fmod_MarkerTrack_addTransitionRegion

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

The description mentions the return type (TransitionRegion ManagedObject) but does not disclose side effects, required permissions, or constraints such as valid positions or lengths. With no annotations, more behavioral context would be helpful.

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 a single sentence plus a reference note. It is concise and front-loads the purpose. However, it could be slightly improved with bullet points or clearer structure for complex parameters.

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 tool's complexity (4 params, no output schema), the description covers the basic purpose and return type but lacks explanation of what a transition region is, its difference from regions/markers, and any usage context. It is adequate but not comprehensive.

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 already has 100% coverage with descriptions for all parameters. The description adds minimal extra meaning beyond restating the schema. It reiterates 'position' and 'length' but does not clarify their format or constraints.

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 action: adding a transition region to a track with position and length, and that it returns a ManagedObject. It distinguishes from sibling MarkerTrack tools (addNamedMarker, addRegion, addTransitionMarker) by specifying 'transition region'.

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 provide explicit guidance on when to use this tool versus alternatives like addTransitionMarker or addRegion. The usage is implied from the action 'add transition region', but no contextual when-to-use or when-not-to-use advice is given.

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