+
+Execute Phase 1 - Foundation from PROMPT.md.
+
+You are building the Ralph PRD Generator CLI tool.
+
+Read PROMPT.md for full specification.
+Read prd.json for feature tracking.
+Read CLAUDE.md for project configuration.
+
+Phase 1 tasks:
+1. Set up TypeScript project with all dependencies
+2. Configure tsup, vitest, eslint
+3. Implement CLI framework with Commander.js
+4. Implement config management for API key storage
+5. Create basic project structure
+6. Write tests for config and CLI
+
+For each feature:
+1. Write tests first
+2. Implement the feature
+3. Run: npm run build && npm run test && npm run lint
+4. If all pass, update prd.json by setting passes to true for completed features
+5. Commit with descriptive message
+6. Append progress to progress.txt
+
+When ALL Phase 1 features in prd.json have passes set to true:
+Output <promise>PHASE_1_COMPLETE</promise>
+
+If blocked after 10 attempts on same issue:
+Document in progress.txt and output <promise>PHASE_1_BLOCKED</promise>
