vibekit_create_app

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states the action without revealing what happens after creation, whether the app is immediately available, any costs, or reversibility. This is a significant gap for a creation tool that likely has side effects.

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 with no filler. It is front-loaded with the verb and resource, making it immediately scannable and appropriate in length.

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 two-parameter tool with complete schema coverage, the description is adequately complete. It lacks an explicit statement about the return value or post-creation behavior, but the interface is simple and the schema covers the necessary invocation details, so this is a minor gap.

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 schema covers 100% of parameters with clear descriptions, so the baseline is 3. The description adds a hint by mentioning 'template' but does not go beyond the schema's explanations for either parameter, offering no additional semantic value.

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 ('create') and a clear resource ('new hosted app') with a qualifier ('from a template'). This makes the tool's purpose immediately obvious and distinguishes it from sibling tools like deploy, redeploy, or delete_app, which involve different lifecycle stages.

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 implies usage for initial app creation via the phrase 'new hosted app', but it provides no explicit guidance on when to use this versus alternatives, nor any exclusions or prerequisites. It is not misleading, but the guidance is purely implicit.

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