Introducing Edda — Automatic Session Memory for Claude Code

[fagemx]

What is Edda?

Edda adds automatic cross-session memory to Claude Code. When you work across multiple sessions, context resets — the agent forgets what it decided, retries rejected paths, and loses momentum.

Edda fixes this by hooking into Claude Code's lifecycle:

1. Hooks capture session activity automatically (commands, edits, decisions)
2. At session end, Edda digests the transcript into structured events
3. Next session start → relevant context injected back into the agent

No manual recording needed. Everything runs in the background after edda init.

Multi-Agent Coordination

When multiple Claude Code agents work on the same repo, Edda coordinates them automatically:

• Peer discovery — each agent sees what others are working on
• Scope claims — prevent file conflicts between agents
• Binding decisions — shared architectural decisions across sessions
• Real-time monitoring — edda watch shows all sessions in a TUI

Key Design Choices

• Local-first — all data in .edda/ (SQLite + local files), no cloud
• Deterministic — same query, same result, every time
• Zero API cost — no LLM calls, no embeddings, no vector DB
• Agent-native — designed to run silently via hooks, not as "another tool to maintain"

Quick Start

# Install
curl -sSf https://raw.githubusercontent.com/fagemx/edda/main/install.sh | sh

# Or via Homebrew
brew install fagemx/tap/edda

# Or via cargo
cargo install edda

# Initialize in your project
edda init

That's it. Start a Claude Code session and Edda works in the background.

Useful Commands

edda context               # see what the agent sees at session start
edda ask "cache"           # query past decisions
edda log --tag decision    # filter event log
edda search query "auth"   # full-text search across transcripts
edda watch                 # real-time TUI

Integration

• Claude Code — fully supported via lifecycle hooks
• OpenClaw — supported via bridge plugin
• Any MCP client (Cursor, Windsurf, etc.) — 7 tools via edda mcp serve
