What is this?

When you build with Claude, your work is split across two places: you sketch ideas and plan in claude.ai, then do the real work in Claude Code in your terminal. Those two sides don't share memory, and context evaporates between sessions, between chats, and whenever the context window compacts.

mm closes that gap. It's a set of Claude Agent Skills plus a small PowerShell installer that gives you:

• One shared memory for every project, stored as plain markdown in an Obsidian vault (passport, handoff, session history).
• A prompt bridge so an idea worked out in claude.ai becomes a clean, self-contained task you paste into Claude Code.
• A simple lifecycle — start a project, resume it, save a session, hand off to a new chat — with no copy-pasting your whole history every time.

Everything is markdown and files. No database, no cloud, no lock-in.

How it works

mm spans three environments that share state through files, not magic:

flowchart LR
    A["claude.ai<br/>(ideas, planning)<br/>mm-web-bridge skill"]
    B["Claude Code / PowerShell<br/>(real work)<br/>10 mm-* skills"]
    C["Obsidian vault<br/>(shared memory)<br/>passport · handoff · sessions"]

    A -- "self-contained prompt<br/>(copy-paste)" --> B
    B -- "writes notes" --> C
    C -- "passport + handoff<br/>loaded into Project Knowledge" --> A
    C -- "read on resume" --> B

• claude.ai side is a single skill (mm-web-bridge): it challenges your idea, checks fast-moving tech against the live web, and composes the prompt you'll run in Claude Code.
• Claude Code side is 10 mm-* skills that do the work and keep the vault up to date.
• Obsidian is just the folder where the markdown lives. Obsidian indexes it for you; mm reads and writes the files directly.

Quick start

Prerequisites

• Claude Code CLI
• Windows + PowerShell (primary platform — see Cross-platform below)
• An Obsidian vault (any folder works; Obsidian itself is optional but recommended)

Install (Claude Code side)

# 0. (first time only) launch Claude Code once so ~/.claude/skills exists
# 1. Clone
git clone https://github.com/mworldorg/markdown-memory.git
cd markdown-memory

# 2. Register the skills (junctions into ~/.claude/skills + sets MM_REPO_ROOT)
#    If PowerShell blocks the script, run instead:
#    powershell -ExecutionPolicy Bypass -File scripts/register-skills.ps1
powershell scripts/register-skills.ps1

# 3. RESTART Claude Code (skills load at session start), then personalize:
/mm setup

# 4. Create your first project's passport (run inside the project folder):
/mm new

Connect the claude.ai side

1. Create a Project in claude.ai for your work.
2. Add your project's passport.md and handoff.md to Project Knowledge.
3. Load the mm-web-bridge skill into that Project (claude.ai → Customize → Skills → Upload a skill). After /mm setup, upload your personalized copy from claude-ai-skills/_generated/mm-web-bridge/ — the committed claude-ai-skills/mm-web-bridge/ is a template with placeholder persona.
4. First message in a new chat:

   "Read handoff.md and passport.md, tell me where we are and suggest the next step."

The loop

/mm resume   →   discuss in claude.ai   →   paste prompt into Claude Code   →   /mm save   →   /mm next

Skills

Ten skills on the Claude Code side, plus one on the claude.ai side — and vendored external skills (see Integrations).

Integrations

mm cooperates with several external tools and bodies of work. Where it builds on someone else's project, that project keeps its own license and attribution.

• GSD — phase-based planning framework. mm reads GSD state (.planning/ / .gsd/) and cooperates with it; it never writes there. (deepest integration)
• Karpathy guidelines — four meta-principles (think before coding, simplicity first, surgical changes, goal-driven) applied across both the Claude Code and claude.ai sides. MIT. (external Claude Code plugin — install separately, see Optional plugins below)
• context-mode — in-session context optimization and continuity. See Memory layers for how it relates to mm. Elastic License 2.0 (source-available). (external Claude Code plugin — install separately, see Optional plugins below)
• prompt-frameworks — CRISPE / XML / PERSONA / HYPOTHESIS templates used by mm-bridge. Inspired by awesome-claude-prompts, MIT.
• claude-code-telegram — optional Telegram bridge, off by default. MIT.
• ECC — everything-claude-code — two skills vendored per-piece into vendor/: ecc-security-review (markdown security checklist; renamed to avoid clashing with the built-in /security-review) and ecc-search-first (research-before-coding workflow). The rest of ECC (AgentShield, plugin, hooks, ~246 skills) is not included. MIT © Affaan Mustafa. (per-skill vendoring mechanism — see vendor/README.md)

Two memory layers

mm and context-mode solve different problems and don't overlap:

• context-mode keeps a single session alive — it survives auto-compaction and --resume by rebuilding your working state inside Claude Code.
• mm keeps long-term project history — decisions, handoffs, and session notes that persist across sessions and across chats, in the Obsidian vault.

If you use both, context-mode already handles compaction; mm doesn't try to.

Optional plugins

Karpathy guidelines and context-mode are external Claude Code plugins (not bundled in this repo). mm cooperates with them but works without them. To install:

# Karpathy coding guidelines (think-before-coding, simplicity, surgical, goal-driven)
/plugin marketplace add forrestchang/andrej-karpathy-skills
/plugin install andrej-karpathy-skills@karpathy-skills

# context-mode (in-session context optimization + continuity across compaction)
/plugin marketplace add mksglu/context-mode
/plugin install context-mode@context-mode

Cross-platform

mm is cross-platform! It is fully supported on Windows, macOS, and Linux:

• Windows: Use powershell scripts/register-skills.ps1 for PowerShell or python3 scripts/register-skills.py.
• macOS / Linux: Use python3 scripts/register-skills.py (which sets up symlinks in ~/.claude/skills and exports MM_REPO_ROOT in your shell profile like .zshrc or .bashrc).

For the optional Telegram bridge:

• Windows: Use powershell scripts/install-tg-bridge.ps1.
• macOS / Linux: Use python3 scripts/install-tg-bridge.py.

Conventions

• Personal data never lands in committed files. Your name and paths live in a gitignored mm-config.local.json written by /mm setup. The committed config stays a generic template.
• Single source of truth for versions — config.version. Per-skill version: fields are intentionally granular.
• Skills preview before they write, and never write into GSD's .planning/ / .gsd/.

Documentation

• passport.md — the per-project source of truth (architecture, conventions, constraints)
• docs/ — deeper guides (Telegram bridge, config loading, etc.)

Contributing

Issues and PRs welcome. New skills go in skills/your-skill/SKILL.md with YAML frontmatter; claude.ai skills go in claude-ai-skills/ (they are not junctioned into Claude Code).
