Open Insta360 Studio

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

Annotations already establish that this is non-read-only but non-destructive and idempotent; the description reinforces this with 'if closed' and clarifies the scope with 'no project edits'. It does not describe failure behavior or whether the launch call returns immediately, but the wait_ready handoff covers the main sequencing concern.

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?

Two short sentences, front-loaded with the action and condition. The follow-up guidance and scope exclusion are stated without filler.

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 launch tool with annotations and no output schema, the description gives enough information to call it correctly and tells the agent what to do next. It could mention failure modes or whether the process is launched detached, but those are minor gaps for this simple operation.

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 zero parameters, so there is no parameter documentation burden; the schema also disallows additional properties. A baseline 4 is appropriate because the description adds no parameter semantics beyond the empty 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 uses a specific verb and resource: starting the pinned Studio installation. It also distinguishes its role from the sibling studio_wait_ready by assigning window-readiness handling to that 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?

It explicitly states when to use it: only if Studio is closed. It also names the follow-up alternative, wait_ready, for waiting on the window and excludes project edits.

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