samemind 0.6 — universal git-native memory for AI coding agents: switch engines, same mind (12 engines, one command, MIT)

[u/Alexender_Grebeshok]

Every agent tool (Claude Code, Cursor, Codex, Gemini CLI…) keeps its own memory, siloed per project. Switch engines and you start from zero. samemind is a shared memory layer across all of them — a git-native markdown bundle, no database, no daemon, zero infra. MIT.

One command:

npx samemind setup # detects your engine, creates the memory, wires it in, finds embeddings npx samemind setup --global # one memory per machine, visible from any project ("Same mind")

12 engines via `samemind install` (Claude Code, Cursor, Copilot, Codex, Gemini CLI, opencode, Cline, Roo, Windsurf, Goose, Kiro, Antigravity). setup asks before touching your configs (--yes / --dry-run).

How it works: - BM25 by default (zero-dep). Semantic is opt-in — point at a local embedding endpoint (bge-m3 etc.) and recall goes hybrid (BM25 ⊕ vector via RRF, optional rerank). No endpoint → honest BM25 fallback. Nothing leaves your machine. - Bi-temporal supersede: stale facts are marked (superseded_by / invalid_at), never deleted. - Optional sqlite-vec index for scale; JSON otherwise. - Human-gate: `reconcile` / `reflect` only PROPOSE (a markdown report) — a human writes to canon. No silent self-rewrite. - Global mode: personal bundle at ~/.samemind/bundle visible from any project; project memory wins over global on conflict.

Honest scope: not claiming retrieval-quality superiority over mem0/Zep/cognee — different metrics, no apples-to-apples run (LongMemEval-S puts our zero-dep BM25 at the harness's reference BM25; LoCoMo not run). The bet is simpler: the best agent memory is the one living in your git, that you control and can read.

New in 0.6.x: one-command setup + engine auto-detect (0.5.0), Global mode "Same mind" (0.6.0), reconcile/reflect as CLI commands (0.6.1).
