Initial commit: Clean DSS implementation
Migrated from design-system-swarm with fresh git history.
Old project history preserved in /home/overbits/apps/design-system-swarm
Core components:
- MCP Server (Python FastAPI with mcp 1.23.1)
- Claude Plugin (agents, commands, skills, strategies, hooks, core)
- DSS Backend (dss-mvp1 - token translation, Figma sync)
- Admin UI (Node.js/React)
- Server (Node.js/Express)
- Storybook integration (dss-mvp1/.storybook)
Self-contained configuration:
- All paths relative or use DSS_BASE_PATH=/home/overbits/dss
- PYTHONPATH configured for dss-mvp1 and dss-claude-plugin
- .env file with all configuration
- Claude plugin uses ${CLAUDE_PLUGIN_ROOT} for portability
Migration completed: $(date)
🤖 Clean migration with full functionality preserved

|
||||
```
|
||||
|
||||
### Python Core Integration
|
||||
|
||||
Wraps these modules from `dss-mvp1/dss/translations/`:
|
||||
|
||||
```python
|
||||
from dss.translations.loader import TranslationDictionaryLoader
|
||||
from dss.translations.writer import TranslationDictionaryWriter
|
||||
from dss.translations.validator import TranslationValidator
|
||||
from dss.translations.merger import ThemeMerger
|
||||
from dss.translations.canonical import (
|
||||
DSS_CANONICAL_TOKENS,
|
||||
DSS_TOKEN_ALIASES,
|
||||
DSS_CANONICAL_COMPONENTS,
|
||||
get_canonical_token_categories,
|
||||
)
|
||||
```
|
||||
|
||||
### Handler Registration
|
||||
|
||||
In `handler.py._initialize_tools()`:
|
||||
```python
|
||||
# Register Translation tools
|
||||
for tool in TRANSLATION_TOOLS:
|
||||
self._tool_registry[tool.name] = {
|
||||
"tool": tool,
|
||||
"category": "translations",
|
||||
"requires_integration": False
|
||||
}
|
||||
```
|
||||
|
||||
In `handler.py.execute_tool()`:
|
||||
```python
|
||||
elif category == "translations":
|
||||
result = await self._execute_translations_tool(tool_name, arguments, context)
|
||||
```
|
||||
|
||||
New method `handler.py._execute_translations_tool()`:
|
||||
```python
|
||||
async def _execute_translations_tool(
|
||||
self,
|
||||
tool_name: str,
|
||||
arguments: Dict[str, Any],
|
||||
context: MCPContext
|
||||
) -> Dict[str, Any]:
|
||||
"""Execute a Translation tool"""
|
||||
if "project_id" not in arguments:
|
||||
arguments["project_id"] = context.project_id
|
||||
|
||||
translation_tools = TranslationTools()
|
||||
return await translation_tools.execute_tool(tool_name, arguments)
|
||||
```
|
||||
|
||||
### Server Integration
|
||||
|
||||
In `server.py`:
|
||||
```python
|
||||
from .integrations.translations import TRANSLATION_TOOLS
|
||||
|
||||
# In list_tools():
|
||||
tools.extend(TRANSLATION_TOOLS)
|
||||
|
||||
# In call_tool():
|
||||
translation_tool_names = [tool.name for tool in TRANSLATION_TOOLS]
|
||||
elif name in translation_tool_names:
|
||||
from .integrations.translations import TranslationTools
|
||||
translation_tools = TranslationTools()
|
||||
result = await translation_tools.execute_tool(name, arguments)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Implementation Details
|
||||
|
||||
### TranslationIntegration Class

||||
|
||||
**Initialization:**
|
||||
- Takes optional config dictionary
|
||||

### TranslationTools Executor Class
|
||||
|
||||
**Purpose:** MCP tool executor wrapper
|
||||
|
||||
**Method:** `execute_tool(tool_name: str, arguments: Dict[str, Any])`
|
||||
|
||||
**Features:**
|
||||
- Routes all 12 tool names to correct handler methods
|
||||
- Removes internal argument prefixes
|
||||
- Comprehensive error handling
|
||||

|
||||
|
||||

|
||||
|
||||
## Error Handling
|
||||
|
||||
All methods include try/catch blocks with:
|
||||
- Descriptive error messages
|
||||
- Return format: `{"error": "message", ...}`
|
||||
- Fallback values for missing dictionaries
|
||||
- Path validation to prevent traversal attacks
|
||||
|
||||
### Example Error Responses
|
||||
|
||||
```json
|
||||
{
|
||||
"error": "Dictionary not found: css",
|
||||
"project_id": "proj-123",
|
||||
"available": ["figma", "custom"]
|
||||
}
|
||||
```
|
||||
|
||||
```json
|
||||
{
|
||||
"error": "Validation failed",
|
||||
"errors": ["Invalid DSS token path: color.unknown"],
|
||||
"warnings": ["Token color.primary.50 not in canonical set"]
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Type Hints & Documentation
|
||||
|
||||
### Complete Type Coverage

||||
|
||||
All methods include:
|
||||
- Parameter type hints
|
||||
- Return type hints (`Dict[str, Any]`)
|
||||
- Optional parameter defaults
|
||||
- Description in docstrings
|
||||
|
||||
### Example
|
||||
|
||||
```python
|
||||
async def resolve_theme(
|
||||
self,
|
||||
project_id: str,
|
||||
base_theme: str = "light",
|
||||
include_provenance: bool = False
|
||||
) -> Dict[str, Any]:
|
||||
"""
|
||||
Resolve complete project theme.
|
||||
|
||||
Args:
|
||||
project_id: Project ID
|
||||
base_theme: Base theme (light or dark)
|
||||

|
||||
|
||||
Returns:
|
||||
Resolved theme with tokens and custom props
|
||||
"""
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## MCP Schema Compliance
|
||||
|
||||
### Tool Definition Pattern
|
||||
|
||||
All 12 tools follow MCP specification:
|
||||
|
||||
```python
|
||||
types.Tool(
|
||||
name="tool_name",
|
||||
description="Clear human-readable description",
|
||||
inputSchema={
|
||||
"type": "object",
|
||||
"properties": {
|
||||
"param_name": {
|
||||
"type": "string|object|array|boolean|number",
|
||||
"description": "Parameter description",
|
||||
"enum": ["option1", "option2"], # if applicable
|
||||
"default": "default_value" # if optional
|
||||
}
|
||||
},
|
||||
"required": ["required_params"]
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
### Input Schema Examples
|
||||
|
||||
**Dictionary CRUD:**
|
||||
- Token mappings: `{"source_token": "dss_canonical_path"}`
|
||||
- Component mappings: `{"source_component": "DSS[variant=X]"}`
|
||||
- Custom props: `{"color.brand.custom": "#hex"}`
|
||||
|
||||
**Theme Configuration:**
|
||||
- Base themes: `enum: ["light", "dark"]`
|
||||
- Categories: `enum: ["color", "spacing", "typography", ...]`
|
||||
|
||||
**Code Generation:**
|
||||
- Formats: `enum: ["flat", "nested", "style-dictionary"]`
|
||||
- Output path: Optional file path for writing
|
||||
|
||||
---
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### List Dictionaries
|
||||
```python
|
||||
response = await tools.execute_tool("translation_list_dictionaries", {
|
||||
"project_id": "acme-web",
|
||||
"include_stats": True
|
||||
})
|
||||
# Returns: {
|
||||
# "dictionaries": [
|
||||
# {"source": "figma", "token_count": 45, ...},
|
||||
# {"source": "css", "token_count": 23, ...}
|
||||
# ],
|
||||
# "has_translations": True,
|
||||
# "translations_dir": "/project/.dss/translations"
|
||||
# }
|
||||
```
|
||||
|
||||
### Create Dictionary
|
||||
```python
|
||||
response = await tools.execute_tool("translation_create_dictionary", {
|
||||
"project_id": "acme-web",
|
||||
"source": "css",
|
||||
"token_mappings": {
|
||||
"--brand-primary": "color.primary.500",
|
||||
"--brand-secondary": "color.secondary.500"
|
||||
},
|
||||
"custom_props": {
|
||||
"color.brand.acme.highlight": "#ff6b00"
|
||||
},
|
||||
"notes": ["Mapped from legacy CSS variables"]
|
||||
})
|
||||
```
|
||||
|
||||
### Resolve Theme
|
||||
```python
|
||||
response = await tools.execute_tool("theme_resolve", {
|
||||
"project_id": "acme-web",
|
||||
"base_theme": "light",
|
||||
"include_provenance": True
|
||||
})
|
||||
# Returns: {
|
||||
# "tokens": {
|
||||
# "color.primary.500": {
|
||||
# "value": "#3b82f6",
|
||||
# "source_token": "--brand-primary",
|
||||
# "provenance": ["figma", "css"]
|
||||
# }
|
||||
# },
|
||||
# "custom_props": {...}
|
||||
# }
|
||||
```
|
||||
|
||||
### Export CSS
|
||||
```python
|
||||

|
||||
"project_id": "acme-web",
|
||||
"base_theme": "light",
|
||||
"output_path": "src/styles/tokens.css"
|
||||
})
|
||||
# Returns: {
|
||||
# "written": True,
|
||||
# "output_path": "/path/to/project/src/styles/tokens.css",
|
||||
# "token_count": 89,
|
||||
# "custom_prop_count": 2
|
||||
# }
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Workflow Integration
|
||||
|
||||
### Workflow 2: Load Project Theme into Storybook
|
||||
|
||||
1. **Check translations** → `translation_list_dictionaries`
|
||||
2. **Resolve theme** → `theme_resolve` (light/dark)
|
||||
3. **Generate Storybook theme** → `storybook_generate_theme`
|
||||
4. **Configure Storybook** → `storybook_configure`
|
||||
|
||||
### Workflow 3: Apply Design to Project
|
||||
|
||||
1. **View canonical** → `theme_get_canonical_tokens`
|
||||
2. **Create mappings** → `translation_create_dictionary`
|
||||
3. **Add custom props** → `theme_add_custom_prop`
|
||||
4. **Validate** → `translation_validate_dictionary`
|
||||
5. **Resolve theme** → `theme_resolve`
|
||||
6. **Export CSS** → `codegen_export_css`
