vibekit_create_app

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

The description is extremely minimal with no annotations. It fails to disclose any behavioral traits such as whether the app is started immediately, if it's synchronous, or what side effects occur (e.g., costs, resource allocation). The agent is left without crucial context.

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, front-loaded sentence with no redundant words. It is concise, though perhaps too brief for the complexity involved.

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 purpose (creating an app from a template) and the lack of output schema, the description is incomplete. It does not mention the return value (e.g., app details), required permissions, or any follow-up steps needed after creation.

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%: both parameters have descriptions in the input schema. The tool description does not add extra meaning beyond that, so a baseline of 3 is appropriate.

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 (create) and the resource (hosted app from template), using a specific verb and resource. It distinguishes from sibling tools like vibekit_list_templates (which lists templates) or vibekit_deploy (which deploys existing app).

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 provides no guidance on when to use this tool vs. alternatives like vibekit_deploy or vibekit_start_app. It does not state prerequisites or when not to use it, leaving ambiguity for an AI agent.

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