+# Agent Workflow
+
+## Before Making Changes
+1. Read PLAN.md to understand current phase and priorities
+2. Check LESSONS.md for relevant past decisions
+3. Read existing code before editing — never guess at file contents
+
+## After Making Changes
+1. Run `npm run build` to verify no errors
+2. Update PLAN.md checkboxes when a feature is complete
+3. Add important learnings to LESSONS.md
+4. Commit with conventional message format
+
+## When Stuck
+- Check LESSONS.md for similar past issues
+- Prefer simple solutions over clever ones
+- If a decision has trade-offs, document the reasoning in LESSONS.md
+
+## Code Quality
+- Fix all TypeScript errors before committing
+- Fix all linter warnings before committing
+- No `console.log` in committed code (use only for debugging)
+- Remove unused imports and variables
