memstack

MemStack™

The structured skill framework for Claude Code — 128 professional skills for deployment, security, databases, content, marketing, and more.

Skills activate automatically when you need them. Say "deploy this to Railway" and the right skill loads on demand.

Install

MemStack installs in two parts: the skills (via the Claude Code plugin marketplace) and the engine (the MCP skill loader, via PyPI). You need both — the loader reads skill files from the installed marketplace plugin.

Step 1 — Install the free skills (run inside Claude Code):

/plugin marketplace add cwinvestments/memstack
/plugin install memstack@cwinvestments-memstack

Step 2 — Install the engine (run in your terminal):

pip install memstack-skill-loader
claude mcp add --scope user memstack-skills -- python -m memstack_skill_loader

Step 3 — Restart Claude Code, then type list skills to verify. You should see the 85 free skills.

Step 4 — (Pro only) unlock the 43 Pro skills — see Unlock Pro Skills below.

See GETTING-STARTED.md for detailed setup or troubleshooting.

Tier Structure

Tier	Skills	Access
Free	85 skills	Included with MemStack™ base
Pro	128 total (85 free + 43 Pro-exclusive)	Requires Pro Skill Loader (memstack.pro)

Architecture note: Pro skills are license-gated — when you activate a valid Pro key, the loader downloads them from our server to ~/.memstack/pro-skills. Free users see free skills only; Pro license holders unlock the full catalog. This design keeps a single source codebase with no separate repos or branches for Pro content.

Pro-exclusive skills (43): consolidate, context-db, api-docs, branching, multi-agent, codebase-index, doc-index, diagram-generator, browser-use, session-restore, drift-detection, mcp-builder, claude-api-helper, test-generator, log-analyzer, performance-profiler, dependency-auditor, git-worktrees, error-handler, web-scraper, advanced-security, env-manager-pro, hooks-integration, developer-growth-analysis, meeting-insights-analyzer, gtm-validator, rag-builder, model-router, video-pipeline, governor-pro, config-audit, burn, frontend-design, us-privacy-compliance, ios-app-store, database-architect, database-migration, api-load-tester, social-media, council, checkpoint, nextjs-conventions, python-conventions — these require an active Pro license.

New skill rule: All newly added skills default to Pro-exclusive. After 90 days, they drop to the free tier unless marked permanent-Pro.

Unlock Pro Skills

Complete the Install steps above first (marketplace + engine). Then, in Claude Code, ask Claude to run:

activate_license(key="your-key", email="[email protected]")

Pro skills download automatically from our server to ~/.memstack/pro-skills — there is no separate marketplace step for Pro. Your key is saved permanently — no environment variables needed.

Alternative: You can also set MEMSTACK_PRO_LICENSE_KEY as an environment variable instead of using activate_license. Use setx on Windows or add to ~/.bashrc on Mac/Linux, then restart your terminal and Claude Code.

Updating

MemStack updates through three independent channels — refresh whichever you need, then restart Claude Code:

1. Free skills (including newly released ones) — in Claude Code:

/plugin marketplace update cwinvestments-memstack

then /reload-plugins (or restart Claude Code).

Fallback: if a new skill doesn't appear (marketplace version-detection can be unreliable), re-run /plugin install memstack@cwinvestments-memstack. As a last resort, clear the cached plugin and reinstall it.

2. Pro skills — auto-update within 24 hours. To force an immediate re-download, ask Claude to run the refresh_pro_skills tool.

3. Engine (the skill loader itself) — in your terminal:

pip install --upgrade memstack-skill-loader

Free Base (Included)

Everything from MemStack free:

• SQLite-backed persistent memory with semantic vector search
• Deterministic hooks (commit safety, build verification, secret scanning)
• 17 core skills (Echo, Diary, Work, Forge, Scan, Governor, etc.)
• TTS voice notifications (task complete, needs attention, error alerts)
• TokenStack™ context compression
• Always-on rules and slash commands
