✨ What is supamem?

supamem is a single-binary CLI that wires up a production-grade memory layer for any AI coding assistant. Drop it into a fresh repo, run supamem init, and your agents instantly gain:

• 🔍 Semantic search over project notes, ADRs, decisions, and past conversations (hybrid sparse+dense retrieval)
• 🤖 MCP server that any compatible client (Claude Code, Cursor, OpenCode) can talk to
• 🪝 Per-client hooks that auto-load relevant memory at session start and on file edits
• 📊 Welford usage stats so you can see what memory is actually being recalled
• 🧪 Eval harness with a 33-query golden corpus to detect retrieval regressions

Battle-tested inside SoftChat (Phases 80.1–80.5) before being extracted into a standalone package every team can adopt.

🎯 Why supamem exists

The problem: Coding agents have no memory between sessions. Every time you open a new conversation in Claude Code / Cursor / OpenCode, the model has zero context about your codebase, past decisions, ADRs, known issues, or conventions. So either:

1. You re-paste 5–15 KB of context at the start of every session (slow, error-prone, costly), or
2. You let the agent flounder — it grep-walks the repo, asks redundant questions, forgets last week's decisions, and rediscovers the same gotchas you already documented six months ago.

The fix: A persistent semantic + structural memory layer that automatically retrieves the right 1–2 KB of context for the current prompt — no manual pasting, no re-explaining, no context blow-out.

Phase 80.1 bench (33 labeled goldens, real Claude Code sessions): −78.5% tokens vs naive whole-doc retrieval at the same recall, p95 73 ms end-to-end.

The full evaluation is the same one we ran inside SoftChat to lock the production pipeline. Methodology: 33 representative dev queries → 4 retrieval arms compared (baseline_union, tuned_current, tuned_hybrid, mem0_vector) → token count + recall CI + latency measured per arm.

📊 Token consumption: agent with memory vs without

Numbers below are per typical 30-turn Claude Code session assuming a real codebase with ~50 ADRs / insights / rules (≈ what SoftChat ships). YMMV — but the ratio between arms holds.

Approach	Tokens/turn	Tokens/30-turn session	Notes
❌ No memory layer	≈ 0 auto-injected, but you paste context manually	30,000–80,000 (manual paste, repeated)	You spend cognitive load on copying instead of building
⚠️ Naive RAG (whole-doc embed)	~5,800 / turn	~174,000	Bloated, recalls big files when you only needed a paragraph
✅ supamem tuned_hybrid	~1,250 / turn	~37,500	Same recall, −78.5% tokens vs naive RAG

💰 Approximate inference cost savings

Anthropic API list pricing (Mar 2026): Sonnet 4.6 = $3 / Mtok input · Opus 4.7 = $15 / Mtok input.

Model	Tokens saved/session vs naive RAG	Cost saved/session	Monthly (110 sessions)
Sonnet 4.6	136,500	$0.41	~$45/dev
Opus 4.7	136,500	$2.05	~$225/dev

A 10-engineer team running Opus saves ~$2,250/month on input tokens alone — without counting the cost of slower iteration, lost decisions, and time spent re-pasting context. Output token savings (less hallucination, fewer back-and-forth turns) compound on top.

🥊 vs the alternatives

	No memory	Naive RAG	mem0 / atomic facts	supamem (tuned_hybrid)
Auto-inject on session start	❌	⚠️	✅	✅
Hybrid sparse+dense retrieval	❌	❌	❌	✅
Code-identifier preservation	❌	✅	❌ (drops names)	✅
Locked schema + golden eval	❌	❌	❌	✅
Multi-client (Claude/Cursor/OpenCode)	❌	❌	⚠️	✅
p95 latency	n/a	~120 ms	~80 ms	73 ms
Token bloat	High (manual)	Highest	Low but lossy	Lowest with full recall

Why hybrid? BM25 catches exact identifiers (ChatService.generate, env-var names, file paths) that dense embeddings smear. Dense catches semantic intent ("how do we handle billing webhooks?") that BM25 misses. RRF fusion combines both rankings so you get the best of each.

Why not mem0? mem0's atomic-fact extraction loses code identifiers — recall on the 33-query bench was 0.015 (effectively zero). Great for personal CRM-style memory, not for code-aware retrieval.

⚡️ 60-second quickstart

# 1. Install (uv is the fastest path)
uv tool install supamem

# 2. Start Qdrant (one-time, ~30s)
docker run -d -p 6333:6333 -p 6334:6334 -v $HOME/.qdrant:/qdrant/storage qdrant/qdrant:latest

# 3. Bootstrap your project
cd your-project
supamem init

# 4. Wire it into your AI client
supamem install --client claude-code   # or cursor, opencode

# 5. Confirm everything is healthy
supamem doctor

That's it. Open Claude Code (or your preferred client) inside the project — the memory tool is already on the menu. ✨

📋 Prerequisites

You only really need two things: Python 3.12+ and Qdrant. Everything else is optional.

🐍 Python 3.12+  ·  click to expand install commands

# macOS (Homebrew)
brew install python@3.12

# Linux (Ubuntu/Debian)
sudo apt install python3.12 python3.12-venv

# Windows (PowerShell)
winget install Python.Python.3.12

We strongly recommend installing uv — the fastest Python package manager:

# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows (PowerShell)
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

🗄️ Qdrant 1.10+  ·  vector database (required)

The simplest path is Docker:

docker run -d --name qdrant \
  -p 6333:6333 -p 6334:6334 \
  -v $HOME/.qdrant:/qdrant/storage \
  qdrant/qdrant:latest

Or with docker compose:

services:
  qdrant:
    image: qdrant/qdrant:latest
    ports: ["6333:6333", "6334:6334"]
    volumes: ["./qdrant_data:/qdrant/storage"]
    restart: unless-stopped

Don't have Docker? Run a managed cluster on Qdrant Cloud (free tier available) and point supamem at the URL via supamem init.

🤖 An MCP-compatible client  ·  pick at least one

Client	Install	Notes
Claude Code	npm install -g @anthropic-ai/claude-code	First-class MCP support
Cursor	Download from cursor.com	Uses MDC rules + MCP
OpenCode	curl -fsSL https://opencode.ai/install | bash	Open-source TUI, MCP native

---

📦 Install

# Recommended: uv (fastest, isolated)
uv tool install supamem

# Alternative: pipx (also isolated)
pipx install supamem

# Plain pip (in a venv)
pip install supamem

Verify:

supamem --version

You should see a colorful banner and the credit line. 🎨

Note: v0.1.0 ships as a git-tag release per D-44. PyPI publish lands in v0.2. To install the pre-release directly from git:

uv tool install git+https://github.com/dzmitrys-dev/supamem@v0.1.0

Cursor

supamem install --client cursor

Patches .cursor/mcp.json and writes .cursor/rules/dual-memory.mdc.

OpenCode

supamem install --client opencode

Updates ~/.config/opencode/opencode.json and writes a session-start hook to ~/.config/opencode/hooks/.

• Indexer chunks Markdown by header (T-1 chunker, 200-token target / 250 soft max)
• Embedders produce sparse (BM25) and dense (MiniLM-L6) vectors
• Retrieval runs both arms in parallel, fuses with reciprocal rank fusion, returns top-k
• MCP server exposes qdrant-find and qdrant-store tools, plus context resources
• Hooks call supamem hook <client> at the right moment, so memory loads transparently
