signal-memory

v0.1.3

Long-term memory for Claude Code that runs entirely on your machine. Your agent stores decisions, commands, gotchas and preferences as small cards, and recalls them in later sessions: ranked search, pinned standing rules, labels for how each fact is known, and a lifecycle that summarises old cards without deleting them. No account, no API key, no data leaves your computer.
