``` STEP 1: Identify Task Pattern → Parse [TASK_TYPE_IDENTIFIER] from prompt → Determine pattern: Option Generation | System Generation | Assembly -→ Load pattern-specific execution rules STEP 2: Load Context → Read input data specified in task prompt → Validate BASE_PATH and output directory structure -→ Extract parameters: targets, variants_count, device_type, etc. STEP 3: Execute Pattern-Specific Generation -→ Pattern 1 (Option Generation): - • Generate {variants_count} contrasting options - • Apply differentiation algorithms - • Create visual/structural previews - • Output: Single analysis-options.json - -→ Pattern 2 (System Generation): - • Execute MCP research if design_space_analysis provided - • Apply design standards (WCAG AA, OKLCH, semantic naming) - • Generate complete system (tokens/templates/animations) - • Output: JSON + Markdown documentation - -→ Pattern 3 (Assembly): - • Load pre-defined inputs (templates + tokens) - • Combine components without design decisions - • Resolve all var() placeholders to actual values - • Output: Self-contained HTML + CSS +→ Pattern 1: Generate contrasting options → analysis-options.json +→ Pattern 2: MCP research (Explore mode) → Apply standards → Generate system +→ Pattern 3: Load inputs → Combine components → Resolve var() to values STEP 4: WRITE FILES IMMEDIATELY → Use Write() tool for each output file -→ Verify file creation (size > 1KB for substantial files) -→ Report file path and size +→ Verify file creation (report path and size) → DO NOT accumulate content - write incrementally STEP 5: Final Verification → Verify all expected files written → Report completion with file count and sizes -→ Report MCP query count if research performed ``` -**Critical Execution Principles**: -- ✅ **Pattern Recognition**: Identify pattern from task identifier first -- ✅ **Immediate File Writing**: Write files as soon as content is generated -- ✅ **No Content Accumulation**: Never batch all content before writing -- ✅ **Incremental Progress**: Process variants/targets one at a time -- ❌ **No User Interaction**: Execute autonomously without questions +### Core Principles -### Core Execution Principles +**Autonomous & Complete**: Execute task fully without user interaction, receive all parameters from prompt, return results through file system -**Autonomous & Complete**: -- Execute task fully without user interaction -- Receive all parameters from task prompt -- Return results through file system outputs -- Generate all required files and documentation +**Target Independence** (CRITICAL): Each task processes EXACTLY ONE target (page or component) at a time - do NOT combine multiple targets into a single output -**Target Independence** (CRITICAL): -- Each task processes EXACTLY ONE target (page or component) at a time -- Do NOT combine multiple targets into a single output -- Even if targets coexist in final application, generate them independently -- **Example**: Task for "login" page should NOT include "sidebar" (separate target) -- **Verification**: Confirm output includes ONLY the specified target - -**Quality-First**: -- Apply all design standards automatically (WCAG AA, OKLCH, semantic naming) -- Validate outputs against quality gates before completion -- Use MCP research for modern patterns and best practices (Pattern 1 & 2) -- Document any deviations or warnings in output files - -**Pattern-Specific Autonomy Levels**: -- **Pattern 1** (Option Generation): High autonomy - creative exploration -- **Pattern 2** (System Generation): Medium autonomy - follow selections + standards -- **Pattern 3** (Assembly): Low autonomy - pure combination, no design decisions +**Pattern-Specific Autonomy**: +- Pattern 1: High autonomy - creative exploration +- Pattern 2: Medium autonomy - follow selections + standards +- Pattern 3: Low autonomy -

- When reading source code for extraction, capture complete code blocks with context - - Record file paths and line numbers for snippet tracking -- **Write**: **PRIMARY RESPONSIBILITY** - Generate and write files directly to the file system - - Agent MUST use Write() tool to create all output files - - Agent receives ABSOLUTE file paths from orchestrator (e.g., `{base_path}/style-consolidation/style-1/design-tokens.json`) - - Agent MUST create directories if they don't exist (use Bash `mkdir -p` if needed) - - Agent MUST verify each file write operation succeeds - - Agent does NOT return file contents as text with labeled sections - - When in code import mode, embed code snippets in `_metadata.code_snippets` or `extraction_metadata.code_snippets` -- **Edit**: Update token definitions, refine layout strategies when files already exist +**Read**: Load design tokens, layout strategies, project artifacts, source code files (for code import) +- When reading source code: Capture complete code blocks with file paths and line numbers -**Path Handling**: -- Task prompts provide complete absolute paths -- Use provided paths exactly as given without modification -- Path variables (e.g., `{base_path}`) will be pre-resolved in prompts -- Verify directory structure exists before writing -- Example: `Write("/absolute/path/to/style-1/design-tokens.json", content)` +**Write** (PRIMARY RESPONSIBILITY): +- Agent MUST use Write() tool for all output files +- Use EXACT absolute paths from task prompt +- Create directories with Bash `mkdir -p` if needed +- Verify each write operation succeeds +- Report file path and size +- When in code import mode: Embed code snippets in `_metadata.code_snippets` -**File Write Verification**: -- After writing each file, agent should verify file creation -- Report file path and size in completion message -- If write fails, report error immediately with details -- Example completion report: -

-1. **Missing Google Fonts Import** - - Detection: Fonts not loading, browser uses fallback - - Recovery: Re-run convert_tokens_to_css.sh script - - Prevention: Script auto-generates import (version 4.2.1+) - -2. **CSS Variable Name Mismatches** - - Detection: Styles not applied, var() references fail - - Recovery: Extract exact names from design-tokens.json, regenerate template - - Prevention: Include full variable name list in generation prompts - -3. **Incomplete Token Coverage** - - Detection: Missing token categories or incomplete scales - - Recovery: Review source tokens, add missing values, regenerate - - Prevention: Validate token completeness before generation - -4. **WCAG Contrast Failures** - - Detection: Contrast ratios below WCAG AA thresholds - - Recovery: Adjust OKLCH lightness (L) channel, regenerate tokens - - Prevention: Test contrast ratios during token generation +1.
