+# Phase 5 Plan 1: Unified Intermediate Directory Summary
+
+**Unified intermediate directory configuration with KB_INTERMEDIATE_PATH support for customizable analysis output paths**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-03-16T15:12:20Z
+- **Completed:** 2026-03-16T15:14:10Z
+- **Tasks:** 3
+- **Files modified:** 3
+
+## Accomplishments
+- Added intermediate_path field to KBSettings with pydantic-settings env var support
+- Updated Pipeline to use settings.intermediate_path as default output directory
+- Updated CLI process_command to default to intermediate_path instead of cwd
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add KB_INTERMEDIATE_PATH config to KBSettings** - `c5b2c66` (feat)
+2. **Task 2: Update Pipeline to use configurable intermediate directory** - `10f4dfa` (feat)
+3. **Task 3: Update CLI to use configurable intermediate directory default** - `7f9caa3` (feat)
+
+## Files Created/Modified
+- `kb_pipeline/config.py` - Added intermediate_path field with default ~/work/intermediate/analysis/
+- `kb_pipeline/pipeline.py` - Changed default output_dir from cwd to settings.intermediate_path
+- `kb-workflow/kb_workflow.py` - Updated process_command to use intermediate_path default
+
+## Decisions Made
+- Default path is ~/work/intermediate/analysis/ (consistent with project conventions)
+- Use pydantic-settings naming convention for env var (KB_INTERMEDIATE_PATH)
+- Preserve output_dir parameter override for testing and special cases
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+One pre-existing test failure detected (test_workflow_skips_completed_steps) - this is unrelated to our changes. The test has a bug where it doesn't mock _ask_rerun_step, causing it to prompt for stdin during pytest. This is a pre-existing issue and not in scope for this plan.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Intermediate directory configuration complete
+- Ready for archive directory implementation
+- Users can now customize intermediate path via KB_INTERMEDIATE_PATH env var
