studio_launch

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

With no annotations, the description carries the full burden. It does add genuine behavioral context by stating 'No plugin required,' implying an OS-level launch rather than a bridge/plugin launch, which matters given siblings like bridge_status and studio_status. However, it omits whether it blocks, whether launching with an existing instance conflicts, and permissions needed.

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?

A single front-loaded sentence with no padding. It is appropriately sized, though the parenthetical could be tightened and could carry more routing information in the same space.

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 launch tool with 100% schema coverage and no annotations, the description covers the core action but leaves return behavior and interaction with an already-running Studio unspecified. Since no output schema exists, some indication of what happens on completion would help.

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 100%, so the schema already documents placeId, placeFile, and universeId. The description echoes the two opening modes but adds no syntax, precedence, or mutual-exclusion detail beyond the schema; baseline 3 applies.

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?

States a specific verb and resource ('Launch Roblox Studio') plus the optional opening modes (local .rbxl/.rbxlx file or published place). It does not distinguish itself from the close sibling studio_open_place, which appears to be a separate operation, so the scope boundary is unclear.

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?

There is no guidance on when to use this versus studio_open_place or the plugin-based launch path. The 'No plugin required' note hints at a context, but it is not framed as a when-to-use condition, and no prerequisites or exclusions are stated.

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