Stop re-explaining your project
to Claude Code.
Claude Code forgets everything between sessions. MemStack™ gives it a memory: verified facts about your project, injected at session start, that age out when they stop being true. Plus 130 battle-tested skills that surface when they're relevant.
Your agent stops believing things that stopped being true.
Every fact MemStack™ remembers carries a date, a source, and how it was learned. When something changes, the old fact gets superseded, not silently overwritten, not blindly trusted. At session start, Claude Code gets the facts that are still true about your project, in under 1,500 tokens. No re-explaining, no stale context, no guessing.
Measured savings. Not estimated.
Most compression claims come from benchmarks: one big payload, best case, lab conditions. Ours comes from a bill: 15.85% average savings across every one of 40,743 production requests logged May through July 2026, 119 million tokens that never got spent, logged request by request in a database you can inspect. Individual transforms hit up to 78% on the right payloads; the fleet-wide number is what your invoice actually feels.
Battle-tested workflows that surface when they're relevant.
Git discipline, database migrations, security scanning, deployments, session handoffs. Skills auto-load based on your task; session management tools are there when you need them.
10 Categories. 130 Skills.
Every skill follows a structured protocol, not vague instructions, but step-by-step workflows refined across real projects.

Install
In Claude Code: /plugin marketplace add cwinvestments/memstack then /plugin install memstack@cwinvestments-memstack (free skills). Then in your terminal. Windows: pip install memstack-skill-loader; Linux/Mac: /usr/bin/python3 -m pip install memstack-skill-loader --break-system-packages. Register the MCP with that same interpreter: claude mcp add --scope user memstack-skills -- python -m memstack_skill_loader (Linux/Mac: swap python for /usr/bin/python3). SSH clone error on a fresh Linux box? Run git config --global url."https://github.com/".insteadOf "git@github.com:" then retry.
Activate
After fully restarting Claude Code: activate_license(key='your-key', email='you@example.com'). Or run the dashboard (Windows: python -m memstack_skill_loader dashboard; Linux/Mac: /usr/bin/python3 -m memstack_skill_loader dashboard), open Settings, paste your key, and click Save & Activate.

Weekly Claude Code tips, new skills, and Pro updates. No spam.
Built in production. Proven in practice.
Battle-tested on AdminStack, EpsteinScan, and real client projects. These aren't theoretical prompts. They're workflows that ship.
I was rebuilding the same mental model of a codebase every single session. MemStack™ fixed the re-explaining problem completely. Started with free and upgraded when I saw the value.
Went from hitting context limits mid-session to running full builds without interruption. The Project skill handoff alone saved me hours of re-prompting every week.
I had a massive CLAUDE.md that was eating tokens every session. Switching to MemStack™ skills that only load when relevant cut my token usage significantly and my sessions actually finish now.
The skill auto-triggering is what got me. I was manually pasting the same context block into every session. Now it just loads. That alone is worth it.
Built and deployed 4 client projects this month using MemStack™ skills. The deployment and database skills especially: they just work every time.
Finally a framework that treats Claude Code like a real dev tool instead of a chatbot. The structured protocols make every session consistent.
