memento или Where Was I

Memento gives Claude Code a real memory: persistent, searchable knowledge that survives across every session, every project, and every device. Your AI remembers your codebase, your team conventions, past decisions, and the conversations you have had with it. Memory is searchable from natural language and editable on the web. The plugin adds nine commands (/wake-up, /recall, /remember, /sleep, /handoff, /pickup, /investigate-and-cache, /scan-environment, /frame), proactive memory skills, and session lifecycle hooks. Free to start. A Memento AGI tier adds 20 autonomous coding commands on top.

Persistent memory for Claude Code — at ~350 tokens ambient cost, with no Docker, no API keys, and no MCP servers. Engram captures your sessions structurally on PreCompact (zero LLM cost), extracts atomic memories via a single lightweight LLM digest (preferences, practices, current context), and detects emergent patterns from your history — files you always edit together, recurring errors, tool usage anomalies — stored as an auditable Obsidian-compatible wiki. Key features: • Per-project handoff notes — at session start you get a narrative message from the last session in this project • Atomic UPSERT memories keyed by topic — latest wins, no drift, no embeddings • Emergent pattern detection (co-edits, error recurrence, project streaks, tool anomalies) • Durable preferences stay global; ephemeral context is scoped per project • 4-flag CLI surface: --stats, --query, --memories, --forget • Everything local: SQLite at ~/.claude/memory.db, markdown wiki at ~/.claude/patterns/
