Summary

MemStack is a structured skill framework for Claude Code, designed to augment AI capabilities with 112 professional skills. It automates complex tasks, enhances productivity through on-demand skill activation, and provides robust session memory and project handoff mechanisms, benefiting developers and power users of Claude Code.

How It Works

The framework operates as a Claude Code plugin, offering a catalog of 112 skills that load dynamically based on user tasks, preventing context bloat. It leverages a SQLite-backed persistent memory with semantic vector search for session recall and includes deterministic hooks for safety checks like commit verification and secret scanning. A tiered access model provides 83 free skills and 29 Pro-exclusive skills, all managed within a single codebase, with Pro access gated by a license key.

Quick Start & Requirements

Installation is performed within Claude Code using /plugin marketplace add cwinvestments/memstack followed by /plugin install memstack@cwinvestments-memstack. Manual setup or troubleshooting details are available in GETTING-STARTED.md. Access to the 29 Pro-exclusive skills requires a MEMSTACK_PRO_LICENSE_KEY environment variable or a license file at ~/.memstack/license.json, obtainable from memstack.pro.

Highlighted Details

• A comprehensive suite of 112 skills spans deployment, security, development, business, content, marketing, and more.
• On-demand skill loading via the MCP catalog system ensures efficient context management.
• SQLite-backed persistent memory with semantic vector search enables deterministic session recall.
• Features include TTS voice notifications, deterministic hooks (commit safety, secret scanning), and Headroom context compression proxy integration.
• SessionStart context injection automatically loads recent diary entries and observations for immediate recall.

Maintenance & Community

The project is attributed to "CW Affiliate Investments LLC." as of 2026, with no specific details on active contributors, community channels (like Discord or Slack), or a public roadmap provided in the README.

Licensing & Compatibility

The project is released under the MIT license, which is highly permissive and generally compatible with commercial use and integration into closed-source projects.

Limitations & Caveats

A significant portion of the advanced features (29 skills) are locked behind a Pro license, requiring a paid subscription. New skills are initially designated Pro-exclusive for 90 days before potentially becoming free. The framework is specifically designed for the Claude Code environment.
