Offline Protocol (hosted)

Preview scaffold

preview_scaffold
Read-onlyIdempotent

Preview what an Offline Protocol starter would contain for an app: workflow, template, packages and file list. A dry run that writes nothing; creating the project needs the local Offline Protocol CLI.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "name": "<name>"
    },
    "name": "preview_scaffold"
  }
}

Input Schema

NameRequiredDescriptionDefault
nameYesProject name / directory slug
promptNoNatural-language app idea (uses the planner)
platformNoRequired when a multi-platform workflow is named without a template
templateNoTemplate name, e.g. react-native-social
workflowNoWorkflow name, e.g. local-handoff, backend-delivery or nearby-service
enableMeshNoEnable mesh SDK for React Native templates (default: true for mesh workflows / mesh templates)
enableOfflineIdNoEnable Offline ID (id-react-native) for React Native templates. Default: true for offline-social-network / offline-id-mesh-chat workflows and react-native-social; auto-switches react-native-mesh-app to react-native-social when true.

A4.2/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds the meaningful behavioral fact that it writes nothing and that creation needs an external CLI, which goes beyond the annotations' safety profile.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences: the first lists what the preview shows, the second clarifies the no-write behavior and points to the CLI. Front-loaded and zero waste.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only preview with full schema coverage and safety annotations, the description covers purpose, scope, and the key no-write constraint. It omits return-shape details, but with no output schema that is a minor gap given the preview nature.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with each parameter richly documented, including conditional rules like platform being required for multi-platform workflows and enableOfflineId's defaulting behavior. The description adds no parameter-level detail beyond the schema, so the baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Preview) and resource (Offline Protocol starter), and enumerates its contents (workflow, template, packages, file list). Clearly distinguishable from siblings like get_template or generate_architecture, which retrieve or generate rather than dry-run preview.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly frames this as a dry run that writes nothing, and notes that actually creating the project requires the local CLI instead. This effectively tells the agent when this tool applies vs. a create action, though it doesn't reference sibling preview/listing tools.

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