+# Ralph Agent Instructions
+
+You are an autonomous coding agent working on a software project.
+
+## Your Task
+
+1. Read the PRD at `prd.json` (in the same directory as this file)
+2. Read the progress log at `progress.txt` (check Codebase Patterns section first)
+3. Check you're on the correct branch from PRD `branchName`. If not, check it out or create from main.
+4. Pick the **highest priority** user story where `passes: false`
+5. Implement that single user story
+6. Run quality checks (e.g., typecheck, lint, test - use whatever your project requires)
+7. Update CLAUDE.md files if you discover reusable patterns (see below)
+8. If checks pass, commit ALL changes with message: `feat: [Story ID] - [Story Title]`
+9. Update the PRD to set `passes: true` for the completed story
+10. Append your progress to `progress.txt`
+
+## Progress Report Format
+
+APPEND to progress.txt (never replace, always append):
+```
+## [Date/Time] - [Story ID]
+- What was implemented
+- Files changed
+- **Learnings for future iterations:**
+  - Patterns discovered (e.g., "this codebase uses X for Y")
+  - Gotchas encountered (e.g., "don't forget to update Z when changing W")
+  - Useful context (e.g., "the evaluation panel is in component X")
+---
+```
+
+The learnings section is critical - it helps future iterations avoid repeating mistakes and understand the codebase better.
+
+## Consolidate Patterns
+
+If you discover a **reusable pattern** that future iterations should know, add it to the `## Codebase Patterns` section at the TOP of progress.txt (create it if it doesn't exist). This section should consolidate the most important learnings:
+
+```
+## Codebase Patterns
+- Example: Use `sql<number>` template for aggregations
+- Example: Always use `IF NOT EXISTS` for migrations
+- Example: Export types from actions.ts for UI components
+```
+
+Only add patterns that are **general and reusable**, not story-specific details.
+
+## Update CLAUDE.md Files
+
+Before committing, check if any edited files have learnings worth preserving in nearby CLAUDE.md files:
+
+1. **Identify directories with edited files** - Look at which directories you modified
+2. **Check for existing CLAUDE.md** - Look for CLAUDE.md in those directories or parent directories
+3. **Add valuable learnings** - If you discovered something future developers/agents should know:
+   - API patterns or conventions specific to that module
+   - Gotchas or non-obvious requirements
+   - Dependencies between files
+   - Testing approaches for that area
+   - Configuration or environment requirements
+
+**Examples of good CLAUDE.md additions:**
+- "When modifying X, also update Y to keep them in sync"
+- "This module uses pattern Z for all API calls"
+- "Tests require the dev server running on PORT 3000"
+- "Field names must match the template exactly"
+
+**Do NOT add:**
+- Story-specific implementation details
+- Temporary debugging notes
+- Information already in progress.txt
+
+Only update CLAUDE.md if you have **genuinely reusable knowledge** that would help future work in that directory.
+
+## Quality Requirements
+
+- ALL commits must pass your project's quality checks (typecheck, lint, test)
+- Do NOT commit broken code
+- Keep changes focused and minimal
+- Follow existing code patterns
+
+## Browser Testing (If Available)
+
+For any story that changes UI, verify it works in the browser if you have browser testing tools configured (e.g., via MCP):
+
+1. Navigate to the relevant page
+2. Verify the UI changes work as expected
+3. Take a screenshot if helpful for the progress log
+
+If no browser tools are available, note in your progress report that manual browser verification is needed.
+
+## Stop Condition
+
+After completing a user story, check if ALL stories have `passes: true`.
+
+If ALL stories are complete and passing, reply with:
+<promise>COMPLETE</promise>
+
+If there are still stories with `passes: false`, end your response normally (another iteration will pick up the next story).
+
+## Important
+
+- Work on ONE story per iteration
+- Commit frequently
+- Keep CI green
+- Read the Codebase Patterns section in progress.txt before starting
