scaffold_kotlin_auth_flow

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does state what artifacts will be created, which is helpful, but it does not explain side effects such as file creation or overwrite behavior, whether configuration is generated, what 'instant' means operationally, or what authentication credentials are required. This is a meaningful transparency gap for a scaffolding and generation tool.

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, dense sentence that front-loads the verb and resource, then efficiently lists the three key deliverables. There is no wordiness or redundant information.

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?

The tool scaffolds authentication flow, which generally involves external configuration, credential handling, and generated source files. The description mentions the deliverables but omits important operational details: what files are created, how the appName is used, whether Google auth requires keys or configuration, and what the tool returns or affects. With no output schema and no annotations, this is insufficient for an agent to invoke it with full confidence.

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 the only parameter, appName, with full description coverage, so the baseline is 3. The description does not add any extra meaning to appName beyond 'Application name', but since the schema already documents it fully, no compensation is needed.

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 gives a specific verb ('scaffolds') and a clear resource ('auth flow') and enumerates the concrete artifacts it produces: a HorizontalPager onboarding tour, a Material 3 Login screen with Google auth, and a state-preserving AuthViewModel. This is specific enough to distinguish it from most sibling tools, though it does not explicitly contrast itself with any of them.

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?

Usage context is implied: an agent would choose this when the project needs authentication scaffolding. However, there is no explicit guidance on when to prefer this over related sibling tools like design_kotlin_ui or scaffold_kotlin_backend, and no mention of prerequisites such as Firebase setup or Google client configuration.

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