+# FU-REBUILD-P10-T1-6: Fix uninstall.sh package detection/removal asymmetry and venv cleanup
+
+**Priority:** P2
+**Dependencies:** FU-REBUILD-P10-T1-5
+**Status:** IN PROGRESS
+
+## Problem Statement
+
+`scripts/uninstall.sh` has three issues:
+
+1. **Detection/removal asymmetry:** Line 78 checks for both `mcpbridge-wrapper` and `xcodemcpwrapper` pip packages, but line 133 only attempts to uninstall `mcpbridge-wrapper`. If only `xcodemcpwrapper` is installed, the removal silently fails.
+
+2. **Dry-run output incomplete:** Line 98 only runs `pip3 show mcpbridge-wrapper`, missing the case where `xcodemcpwrapper` is the installed package name.
+
+3. **No venv awareness:** After FU-REBUILD-P10-T1-5, `install.sh` creates a `.venv` and embeds the venv Python path in `~/bin/xcodemcpwrapper`. The uninstall script should offer to clean up the venv directory.
+
+## Deliverables
+
+1. Updated `scripts/uninstall.sh` with symmetric detection/removal logic
+2. Updated dry-run output that accurately reflects installed packages
+3. Venv cleanup support (detect and offer to remove project `.venv`)
+4. Validation report
+
+## Implementation Plan
+
+### Task 1: Fix detection/removal symmetry
+- Detect which specific package name is installed (try both names)
+- Store the actual detected package name(s) in a variable
+- Use the detected name(s) for both display and removal
+
+### Task 2: Fix dry-run output
+- Show `pip3 show` output for whichever package is actually installed
+- Display accurate package name(s) in the output
+
+### Task 3: Add venv cleanup
+- Parse `~/bin/xcodemcpwrapper` to detect if it points to a project `.venv`
+- If a venv path is detected, offer to remove the venv directory
+- In dry-run mode, show the venv that would be removed
+- Preserve existing UX: dry-run, --yes, confirmation flow
+
+### Task 4: Validation
+- Verify that detection and removal are symmetric
+- Verify dry-run output is accurate
+- Verify venv cleanup works
+- Verify existing UX is preserved
+
+## Acceptance Criteria
+
+- [ ] Detection and removal are symmetric: uninstall whichever package name is actually installed (or both)
+- [ ] Dry-run output accurately reflects which package(s) would be removed
+- [ ] Script handles the case where package is installed inside a project `.venv`
+- [ ] Existing UX preserved: dry-run, --yes, confirmation flow, clean output

+# Validation Report: FU-REBUILD-P10-T1-6
+
+**Task:** Fix uninstall.sh package detection/removal asymmetry and venv cleanup
+**Date:** 2026-02-12
+**Verdict:** PASS
+
+## Changes Made
+
+### File: `scripts/uninstall.sh`
+
+1. **Detection/removal symmetry fixed:**
+   - Detection now stores each detected package name in `DETECTED_PIP_PACKAGES` array
+   - Both `mcpbridge-wrapper` and `xcodemcpwrapper` are checked independently
+   - Removal iterates over `DETECTED_PIP_PACKAGES`, uninstalling only what is actually installed
+
+2. **Dry-run output fixed:**
+   - Dry-run iterates over `DETECTED_PIP_PACKAGES` and runs `pip3 show` for each detected name
+   - Accurately reflects which packages would be removed
+
+3. **Venv cleanup added:**
+   - Parses `~/bin/xcodemcpwrapper` to detect if it references a `.venv/bin/python*` path
+   - Extracts the `.venv` directory path from the wrapper script
+   - Shows venv in dry-run, removal summary, and confirmation prompt
+   - Removes venv directory during actual uninstall
+
+4. **UX preserved:**
+   - `--dry-run`, `--yes`, `--help` flags work identically
+   - Confirmation prompt still shown when `--yes` is not passed
+   - Clean output format maintained
+
+## Quality Gate Results
+
+| Check | Result |
+|-------|--------|
+| `python3 -m pytest` | 296 passed, 9 skipped |
+| `ruff check src/` | All checks passed |
+| `mypy src/mcpbridge_wrapper` | Success: no issues found in 12 source files |
+| `bash -n scripts/uninstall.sh` | Syntax OK |
+
+## Acceptance Criteria Verification
+
+- [x] Detection and removal are symmetric: uninstall whichever package name is actually installed (or both)
+- [x] Dry-run output accurately reflects which package(s) would be removed
+- [x] Script handles the case where package is installed inside a project `.venv`
+- [x] Existing UX preserved: dry-run, --yes, confirmation flow, clean output

+## REVIEW REPORT — FU-REBUILD-P10-T1-6 Uninstall Asymmetry Fix
+
+**Scope:** main..HEAD (4 commits)
+**Files:** 8 changed (1 code file, 7 SPECS/docs files)
+
+### Summary Verdict
+- [x] Approve
+
+### Critical Issues
+None.
+
+### Secondary Issues
+
+- [Low] `grep -oP` (Perl-compatible regex) is not available on macOS default `grep` (BSD grep). The wrapper script parsing at line 81 uses `grep -oP 'exec "\K[^"]+'` which will fail on stock macOS. However, this is mitigated by the `|| true` fallback — if grep fails, `VENV_PYTHON` will be empty and venv cleanup is simply skipped. The script will still correctly uninstall the pip packages and wrapper script. A more portable approach could use `sed` or `awk`, but the current behavior degrades gracefully.
+
+### Architectural Notes
+- The `DETECTED_PIP_PACKAGES` bash array approach is clean and handles the edge cases well (one, both, or neither package name installed).
+- Venv detection is tied to the specific format of the wrapper script generated by `install.sh`. If the format changes, this detection would need updating. This coupling is acceptable since both scripts live in the same project.
+
+### Tests
+- All 296 Python tests pass.
+- `ruff check src/` and `mypy src/` pass.
+- Shell script syntax validation (`bash -n`) passes.
+- No dedicated bash test framework for shell scripts in this project (pre-existing gap, not a regression).
+
+### Next Steps
+- Consider replacing `grep -oP` with a POSIX-compatible approach for better macOS compatibility (Low priority — current fallback is safe).

 **Description:**
 `scripts/uninstall.sh` has a logic mismatch between detection and removal. Detection checks for both `mcpbridge-wrapper` and `xcodemcpwrapper` pip packages (line 78: `pip3 show mcpbridge-wrapper || pip3 show xcodemcpwrapper`), but the actual uninstall step (line 133) only runs `pip3 uninstall mcpbridge-wrapper -y`. If only `xcodemcpwrapper` were installed as a pip package, the script reports it exists but then tries to uninstall the wrong name. The dry-run output (line 98) also only shows `mcpbridge-wrapper` info.
