What it does
MemStack installs in two steps. The Claude Code marketplace plugin brings 87 free skills for deployment, security, databases, content and marketing. The Python package `memstack-skill-loader`, with an MCP server, loads the needed skill at request time, so over a hundred skills do not bloat context. The plugin registers hooks: recent diary and observation summaries are injected at session start, a guard fires before secret reads, and ending a session is blocked until tracked changes pass the checks. Each hook has its own environment kill switch.
Who it is for. Claude Code users who want a ready library of working skills and a session diary in one plugin.
Good fit when
- A Railway deploy skill is invoked with "deploy this to Railway" instead of pasting from chat.
- A new session should pick up the diary and observations of the previous one.
- Secret files need protection from whole-file reads.
- A library of a hundred skills should stay out of context until called.
Not a fit when
- Only free skills are wanted without Python, while the loader installs separately from PyPI.
- Plugins may not download code from an external server.
- One or two skills are enough and a whole framework is overkill.
Example request
Deploy this project to Railway and first make sure secrets will not end up in the repository.Limitations
Of 131 skills, 87 are free and the other 44 need a license key from memstack.pro: the loader downloads them from the developer server into `~/.memstack/pro-skills`. New skills default to the paid set and drop to free after 90 days unless marked permanently paid. Both install steps are required, otherwise the loader cannot find the skill files. Installing with `pip` into a system Python can hit `externally-managed-environment`, so use the `~/.memstack-venv` virtual environment. Hooks block some actions, but the README lists cases they do not cover.
How to disable. Run `/plugin uninstall memstack@cwinvestments-memstack`, remove the `memstack-skill-loader` package and the MCP registration. Single hooks are silenced by variables such as `MEMSTACK_NO_SECRET_GUARD=1`.
FAQ
Are both parts required?
Yes. The plugin brings the skill files and the PyPI loader reads and serves them on request. Without the second step the MCP will not connect.
What is free?
87 of the 131 skills are available at once. The other 44 unlock with a license key through `activate_license`.
What about `externally-managed-environment`?
Create a virtual environment and install into it: `~/.memstack-venv/bin/pip install --upgrade memstack-skill-loader`. Register the MCP against the same Python.
How do I switch off the secret guard?
Set `MEMSTACK_NO_SECRET_GUARD=1`. The hook skips its check and prints a line to stderr.
How do I update the plugin?
Re-run `/plugin install memstack@cwinvestments-memstack` if a new skill does not appear. The loader updates with `pip install --upgrade`.
