/rawgentic-memorypalace:upgrade — Upgrade MemPalace Dependency

Upgrade the mempalace library that powers the memory backend.

Instructions

1. Detect Install Method

mempalace can be installed via pipx, pip, or the plugin's own .venv. Run this to detect which:

echo "=== pipx ===" && pipx list 2>/dev/null | grep -A1 "mempalace" || echo "not in pipx"
echo "=== pip (user) ===" && python3 -c "import mempalace; print(mempalace.__version__)" 2>/dev/null || echo "not in python3"
echo "=== plugin venv ===" && PLUGIN_VENV=$(jq -r '.plugins["rawgentic-memorypalace@rawgentic-memorypalace"][0].installPath' ~/.claude/plugins/installed_plugins.json 2>/dev/null) && "$PLUGIN_VENV/.venv/bin/python3" -c "import mempalace; print(mempalace.__version__)" 2>/dev/null || echo "not in plugin venv"

Determine the install method:

• pipx: pipx list shows package mempalace X.Y.Z → use pipx upgrade mempalace
• pip (user/system): python3 -c "import mempalace" succeeds → use pip install --upgrade mempalace
• plugin venv: plugin venv python can import it → use <plugin-venv>/bin/pip install --upgrade mempalace
• None found: tell the user mempalace is not installed and suggest pipx install mempalace (preferred) or pip install --user mempalace. STOP.

Record the current version from whichever method succeeds.

2. Run the Upgrade

Use the appropriate command based on detected install method:

Method	Upgrade command
pipx	pipx upgrade mempalace
pip (user/system)	pip install --upgrade mempalace
plugin venv	<plugin-venv-path>/bin/pip install --upgrade mempalace

3. Get New Version

Re-check the version using the same Python that had mempalace:

# For pipx:
~/.local/bin/mempalace --version 2>/dev/null || ~/.local/share/pipx/venvs/mempalace/bin/python3 -c "import mempalace; print(mempalace.__version__)"

# For pip:
python3 -c "import mempalace; print(mempalace.__version__)"

4. Compare and Report

Compare the old and new version strings.

If versions are the same:

mempalace is already up to date (v{version}).

If versions differ:

## MemPalace Upgraded

- **Old version:** v{old_version}
- **New version:** v{new_version}
- **Install method:** {pipx|pip|plugin venv}

If the major version changed (e.g., 3.x → 4.x):

⚠️ **Major version change detected** (v{old_major} → v{new_major}).
This may include breaking API changes. Check the mempalace changelog
before restarting sessions. The memory server may need updates.

5. Verify the Upgrade

Run a quick import check using the correct Python to confirm the upgrade didn't break anything:

# Use the same python that has mempalace (pipx venv, system python3, or plugin venv)
<python> -c "from mempalace.palace import get_collection; from mempalace.searcher import search_memories; from mempalace.palace_graph import find_tunnels, follow_tunnels; from mempalace.fact_checker import check_text; print('All imports OK')"

If verification fails, warn the user that the upgrade may have broken compatibility.

STOP after reporting results. Do NOT restart any servers.
