+**Categories**:
+- `analysis/` - pattern.txt, architecture.txt, security.txt, performance.txt, quality.txt (Gemini primary, Codex compatible)
+- `development/` - feature.txt, component.txt, refactor.txt, testing.txt, debugging.txt (Codex primary)
+- `planning/` - task-breakdown.txt, migration.txt (Cross-tool)
+- `automation/` - scaffold.txt, migration.txt, deployment.txt (Codex specialized)
+- `review/` - code-review.txt (Cross-tool)
+- `integration/` - api-design.txt, database.txt (Codex primary)
