total-agent-memory

The only memory layer that learns how you work — not just what you said. Persistent, local memory for AI coding agents: Claude Code, Codex CLI, Cursor, any MCP client. Temporal knowledge graph · procedural memory · AST codebase ingest · cross-project analogy · 3D WebGL visualization.

v12.2.0 — v11 W3 dispatch fix + Codex env alignment (2026-05-24)

Bugfix release. Four v11 W3 MCP tools — memory_recall_iterative, memory_temporal_query, memory_entity_resolve, memory_consolidate_status — were silently broken on main: the dispatcher forwarded an out-of-scope args symbol, the resulting NameError was swallowed by call_tool's exception handler, and clients saw "Error: name 'args' is not defined". Fix passes the per-call args, with regression coverage via tests/test_v11_dispatch_args.py.

Also aligns the Codex installer env with the .tam memory layout (TAM_MEMORY_DIR canonical, CLAUDE_MEMORY_DIR kept as compatibility alias, MEMORY_MODE=fast default) and isolates install tests from real launchctl / systemctl / XDG directories. Full notes in CHANGELOG.md.

v12.1.0 — Claude Code v2.1.145 subagent lineage (2026-05-20)

Claude Code v2.1.139+ emits subagent IDs on every API request (x-claude-code-agent-id / x-claude-code-parent-agent-id HTTP headers, plus the same fields as agent_id / parent_agent_id attributes on the claude_code.tool and claude_code.llm_request OTEL spans). v12.1 wires these through end-to-end:

• Schema (migration 028_agent_lineage.sql) — nullable agent_id and parent_agent_id columns on knowledge, partial indexes (WHERE … IS NOT NULL) so lineage filters are free.
• MCP tools — memory_save and memory_save_fast accept two new optional inputs: agent_id and parent_agent_id. Old callers see no behaviour change.
• extract_transcript.py — reads agent_id / agentId / parent_agent_id / parentAgentId from .jsonl when Claude Code writes them, and falls back to isSidechain=true as a proxy: sessions with any sidechain activity get agent_id = "session-<id>" plus a has-subagent-work tag on their auto-extracted rows.
• KG fact spawned_by — when memory_save carries both ids, the store auto-records TemporalKG.add_fact(agent, "spawned_by", parent, source="agent-lineage", invalidate_previous=False). Idempotent. kg_at(timestamp) and kg_timeline() can now reconstruct the subagent lineage tree at any past moment.

A reconnect of the MCP memory server is required for clients to see the updated inputSchema. Full notes in CHANGELOG.md.

v12.0.0 — rebrand to total-agent-memory (2026-05-16)

The project was renamed from claude-total-memory to total-agent-memory to reflect that it works with every MCP client, not just Claude Code (Cursor, Codex CLI, Cline, Continue, Aider, Windsurf, Gemini CLI, OpenCode — all covered).

Nothing breaks. The old PyPI package (claude-total-memory==11.3.0) is now a deprecation shim that auto-resolves to total-agent-memory>=12.0.0. Legacy imports, CLI binaries, env vars, and the ~/.claude-memory/ directory keep working through automatic migration:

Old	New	Backward-compat
pip install claude-total-memory	pip install total-agent-memory	old name still works (shim + warning)
from claude_total_memory import …	from total_agent_memory import …	old import still works (sys.modules alias + warning)
claude-total-memory CLI	total-agent-memory (alias tam)	old CLI still ships in v12 wheel
CLAUDE_MEMORY_DIR env	TAM_MEMORY_DIR env	old env still respected (deprecation warning)
~/.claude-memory/ dir	~/.tam/ dir	auto-migrated on first run; ~/.claude-memory becomes a symlink to ~/.tam/ so pinned scripts keep working

Six install paths — pick one:

npx -y total-agent-memory connect claude-code            # Node, zero-install
uvx total-agent-memory                                    # Python via uv (fast)
pipx install total-agent-memory                           # Python via pipx (isolated)
brew install vbcherepanov/tap/total-memory                # Homebrew (macOS / Linuxbrew)
docker run -p 37737:37737 -v ~/.tam:/data \
  ghcr.io/vbcherepanov/total-agent-memory:12.2.0          # Docker (multi-arch amd64+arm64)
git clone https://github.com/vbcherepanov/total-agent-memory \
  ~/total-agent-memory && cd ~/total-agent-memory && ./install.sh   # manual

The npx path also wires the MCP entry into the IDE you pass to connect <ide>: claude-code, codex, cursor, cline, continue, aider, windsurf, gemini-cli, opencode.

v11.1 — graph dedup + proactive save nudges

Two client-reported bugs fixed (2026-05-14):

Bug #1 — orphan + duplicate graph_nodes. The graph accumulated case-variant duplicates (Vue / vue / VUE) and type-collision duplicates (vue/concept vs vue/technology created by different extractors), plus orphan nodes when an edge insert failed after both nodes were already committed. Fixed by migration 026_graph_nodes_dedup (name_norm column, triggers, indexes), a case-insensitive UPSERT rewrite of add_node with type-collision detection, a new atomic GraphStore.link_pair() helper, and a one-shot cleanup tool src/tools/merge_duplicate_nodes.py (dry-run by default).

# After upgrade migration 026 applies automatically. Then optionally:
.venv/bin/python src/tools/merge_duplicate_nodes.py --dry-run
.venv/bin/python src/tools/merge_duplicate_nodes.py --apply --add-unique

Verified on a real production DB (8304 nodes): 102 duplicates merged, 1472 stale edges cleaned, UNIQUE constraint installed.

Bug #2 — model never calls memory_save on its own. Sonnet/Haiku skip the priority-10 save rule when SessionStart context fades. v11.1 adds in-session nudges: a counter in ~/.claude-memory/state/ tracks writes-vs-saves per session, and hooks/post-tool-use.{sh,ps1} emits a stdout line that Claude reads as system context on the next turn. Soft nudge at 3 edits with 0 saves, hard at 7, and a MEMORY_FINAL_WARNING on session stop. A new priority-10 rule instructs the model to treat MEMORY_NUDGE as an immediate command.

Tunables: MEMORY_NUDGE_DISABLE=1 to silence; MEMORY_NUDGE_SOFT / _HARD / _STEP to retune (defaults 3 / 7 / 3).

Test coverage: +24 graph tests, +12 nudge tests. Full details in CHANGELOG.md.

v11.0 — production memory engine

v11.0 = production memory engine: fast deterministic memory core + async AI enrichment layer. Default mode is fast: zero LLM, zero Ollama, zero network in the save/search/recall hot path.

The codebase is now split into two layers:

• src/memory_core/* — deterministic facade modules (storage, embeddings, vector_store, classifier, chunker, dedup, cache, graph_links, telemetry, health, embedding_spaces). No LLM imports allowed. Enforced by tests/test_no_llm_hot_path.py.
• src/ai_layer/* — every LLM-touching path (enrichment_worker, summarizer, keyword_extractor, question_generator, relation_extractor, contradiction_detector, reflection, self_improve, plus thin shims for quality_gate / coref_resolver / reranker / query_rewriter). Off-limits to memory_core.

Architecture details and full hot-path audit: docs/v11/audit.md.

Modes

MEMORY_MODE selects the runtime profile. Default is fast.

Mode	Hot-path LLM	Async enrichment	Reranker	Embed fallback	Use when
ultrafast	off	off	off	FastEmbed only (vector index off, FTS-only)	Throughput stress / CI
fast (default)	off	off	off	FastEmbed only, Ollama fallback gated	Production coding-agent loop
balanced	off (sync)	on	off	FastEmbed only	You want LLM-derived facets, but never on the critical path
deep	on (sync)	on	on (when rerank=true)	FastEmbed → Ollama ladder	v10.5 behaviour: quality gate / contradiction / coref / HyDE inline

deep mode reproduces v10.5.0 defaults exactly. Set MEMORY_MODE=deep if you depended on synchronous quality_gate, contradiction_detector, or coref. balanced keeps the same ergonomics but moves enrichment off-thread.

Migration from v10.5: docs/v11/MIGRATION-FROM-V10.md.

v11.0 hot-path benchmark

Warm, in-memory SQLite, MacBook M-series, MEMORY_MODE=fast, MEMORY_ALLOW_OLLAMA_IN_HOT_PATH=false:

metric	p50	p95	p99
save_fast	6.5	9.0	27.8
save_fast cached	0.3	0.4	1.1
search_fast	3.7	4.0	6.2
cached_search	0.0	0.0	0.0

llm_calls = 0, network_calls = 0 across the entire hot path. Reproduce: bin/memory-bench. CI gate: bin/memory-perf-gate. Raw artifact: docs/v11/benchmark.md.

v10.5 → v11.0 — same workload, same script

The v10.5 native bench (benchmarks/v10_5_latency.py) re-run on v11 fast against the recorded v10.5 baseline (benchmarks/results/v10_5_latency.json):

metric	v10.5 sync (with LLM)	v11.0 fast	speedup
save p95	2150.51 ms	8.51 ms	252×
save p99	2178.98 ms	11.09 ms	196×
recall p95	1424.26 ms	5.81 ms	245×
recall p99	1771.70 ms	6.75 ms	262×
LLM calls / save	2-4	0	gate
Network calls / save	1-3	0	gate

Even versus v10.5 without LLM (23.3 ms p95), v11 fast is 2.7× faster — the deterministic-only stages (quality_gate probe, contradiction candidate fetch, episodic event creation, project_wiki refresh) are now fully bypassed in fast mode and queued only when MEMORY_ENRICHMENT_ENABLED=true.

Recall quality is preserved: LongMemEval R@5 = 100% on a 30-question sample; hybrid retrieval (FTS5 + dense + RRF + base graph) is identical to v10.5 except for HyDE / analyze_query LLM expansion which is opt-in via MEMORY_MODE=deep. See docs/v11/benchmark.md for the full table including LoCoMo and per-space embedding load characteristics.

New MCP tools in v11.0

memory_save_fast · memory_search_fast · memory_explain_search · memory_warmup · memory_perf_report · memory_rebuild_fts · memory_rebuild_embeddings · memory_eval_locomo · memory_eval_recall · memory_eval_temporal · memory_eval_entity_consistency · memory_eval_contradictions · memory_eval_long_context

All previous tool names (memory_save, memory_recall, ...) continue to work unchanged.

Multi-embedding-space contract

Every vector row now records embedding_provider / embedding_model / embedding_dimension / embedding_space / content_type / language. Spaces: text / code / log / config. Single Chroma backend; per-space model swap is one env flip:

MEMORY_TEXT_EMBED_MODEL=sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2
MEMORY_CODE_EMBED_MODEL=jinaai/jina-embeddings-v2-base-code   # optional
MEMORY_LOG_EMBED_MODEL=                                       # falls back to TEXT
MEMORY_CONFIG_EMBED_MODEL=                                    # falls back to TEXT

Old chunks stay searchable in their space; new chunks pick up the swapped model. Backfill one space at a time via memory_rebuild_embeddings.

v10.x sections below are preserved as legacy v10.5 behaviour — still available via MEMORY_MODE=deep. The numbers, screenshots, and benchmark blocks dated 2026-04-19 / 2026-04-25 / 2026-04-27 (v10) describe the deep-mode pipeline. v11 replaces defaults, not capabilities.

The problem it solves

AI coding agents have amnesia. Every new Claude Code / Codex / Cursor session starts from zero. Yesterday's architectural decisions, bug fixes, stack choices, and hard-won lessons vanish the moment you close the terminal. You re-explain the same things, re-discover the same solutions, paste the same context into every new chat.

total-agent-memory gives the agent a persistent brain — on your machine, not in someone else's cloud.

Every decision, solution, error, fact, file change, and session summary is:

• Captured — explicitly via memory_save or implicitly via hooks on file edits / bash errors / session end
• Linked — automatically extracted into a knowledge graph (entities, relations, temporal facts)
• Searchable — 6-stage hybrid retrieval (BM25 + dense + graph + CrossEncoder + MMR + RRF fusion), 96.2% R@5 on public LongMemEval
• Private — 100% local. SQLite + FastEmbed + optional Ollama. No data leaves your machine.

60-second demo

You:     "remember we picked pgvector over ChromaDB because of multi-tenant RLS"
Claude:  ✓ memory_save(type=decision, content="Chose pgvector over ChromaDB",
                       context="WHY: single Postgres, per-tenant RLS")

[3 days later, different session, possibly different project directory:]

You:     "why did we pick pgvector again?"
Claude:  ✓ memory_recall(query="vector database choice")
         → "Chose pgvector over ChromaDB for multi-tenant RLS. Single DB
            instance, row-level security per tenant."

It's not just retrieval. It's procedural too:

You:     "migrate auth middleware to JWT-only session tokens"
Claude:  ✓ workflow_predict(task_description="migrate auth middleware...")
         → confidence 0.82, predicted steps:
             1. read src/auth/middleware.go + tests
             2. update session fixtures in tests/
             3. run migration 0042
             4. regenerate OpenAPI spec
           similar past: wf#118 (success), wf#93 (success)

Install

Quickstart — pick one (v12.2.0)

Channel	Command	What it does
npx (Node)	npx -y total-agent-memory connect claude-code	Zero-install. Bootstraps a Python venv in ~/.tam/.venv via uv (or python3 fallback), pulls the PyPI server, wires the MCP entry into your IDE. Replace claude-code with codex / cursor / cline / continue / aider / windsurf / gemini-cli / opencode.
uvx (Python via uv)	uvx total-agent-memory	One-off run with no install. Best for trying without commitment.
pipx (Python isolated)	pipx install total-agent-memory	Installs the total-agent-memory, tam, tam-lookup, lookup-memory binaries on PATH in an isolated venv.
brew (macOS / Linuxbrew)	brew install vbcherepanov/tap/total-memory	Bottle-style install with tam and legacy claude-total-memory symlinks.
Docker (multi-arch)	docker run -p 37737:37737 -v ~/.tam:/data ghcr.io/vbcherepanov/total-agent-memory:12.2.0	Containerized (linux/amd64 + linux/arm64). Dashboard on :37737.
Manual clone	git clone https://github.com/vbcherepanov/total-agent-memory ~/total-agent-memory && cd ~/total-agent-memory && ./install.sh --ide claude-code	Full control. Lets you hack on the server, run benchmarks, and pick which background services to enable. Detailed walkthrough below.

All six channels land at the same MCP server. The npx and ./install.sh paths additionally configure IDE-specific MCP entries and hooks. Other channels start the server bare — you wire the IDE afterwards (see docs/installation.md).

Upgrade from v11.x? Whatever channel you pick will auto-migrate ~/.claude-memory/ → ~/.tam/ on first run and keep a symlink for backward compat. No manual data move required.

---

Detailed paths (manual / Docker / per-IDE)

Two manual paths. Same 60+ tools, same dashboard, different deployment shapes.

IDE matrix (v10.5)

The same MCP server, same tools, same protocol — different installation locations and hook wiring per IDE. The installer (install.sh --ide <name>) automates all of it.

IDE	Skill API	Hook API	Sub-agents	Install command
Claude Code	✅	✅ full	✅	./install.sh --ide claude-code
Codex CLI	✅	✅	❌	./install.sh --ide codex
Cursor	rules-pane	❌	composer	./install.sh --ide cursor
Cline (VS Code)	.clinerules/	❌	❌	./install.sh --ide cline
Continue	rules file	❌	❌	./install.sh --ide continue
Aider	.aider.conf.yml read	❌ ¹	❌	./install.sh --ide aider
Windsurf	.windsurfrules	❌	cascade	./install.sh --ide windsurf
Gemini CLI	.gemini/rules/	⚠️ partial	❌	./install.sh --ide gemini-cli
OpenCode	.opencode/skills/	✅	custom	./install.sh --ide opencode

¹ Aider has no MCP yet — the bridge is via lookup_memory.sh / save_memory.sh shell scripts.

Full per-IDE setup, manual fallbacks, and template snippets: skills/memory-protocol/references/ide-setup.md.

Platform matrix

OS	Command	Background services
macOS 10.15+	./install.sh --ide claude-code	LaunchAgents (launchctl)
Linux (Ubuntu 22.04+, Debian 12+, Fedora 38+)	./install.sh --ide claude-code	systemd --user
WSL2 (Windows 11 + Ubuntu/Debian)	./install.sh --ide claude-code	systemd --user — requires /etc/wsl.conf with [boot] systemd=true; otherwise falls back to shell-loop autostart
Windows 10/11 native	.\install.ps1 -Ide claude-code	Task Scheduler

Full per-platform walkthrough, WSL2 Windows-host-vs-WSL IDE nuances, the wsl -e MCP-command pattern, IDE coverage matrix, and uninstall/diagnostic flows: docs/installation.md.

Path A — native (macOS / Linux / WSL2)

git clone https://github.com/vbcherepanov/total-agent-memory.git ~/total-agent-memory
cd ~/total-agent-memory
bash install.sh --ide claude-code   # or: cursor | gemini-cli | opencode | codex

The installer:

1. Clones + creates ~/total-agent-memory/.venv/
2. Installs deps from requirements.txt and requirements-dev.txt
3. Pre-downloads the FastEmbed multilingual MiniLM model
4. Registers the MCP server via claude mcp add-json memory ... (stored in ~/.claude.json, the canonical store Claude Code actually reads)
5. Copies all hooks (session-*, user-prompt-submit.sh, post-tool-use.sh, pre-edit.sh, on-bash-error.sh, etc.) into ~/.claude/hooks/ and registers them in ~/.claude/settings.json
6. Grants permissions.allow for 20+ mcp__memory__* tools so hook-driven calls don't prompt for confirmation
7. Installs background services for the current OS:
   • macOS — 4 LaunchAgents (reflection, orphan-backfill, check-updates, dashboard) under ~/Library/LaunchAgents/
   • Linux / WSL2 — 7 systemd --user units (*.service, *.timer, *.path) under ~/.config/systemd/user/; gracefully degrades if systemd --user is unavailable (WSL without /etc/wsl.conf)
8. Applies all migrations to a fresh memory.db
9. Starts the dashboard at http://127.0.0.1:37737

Restart Claude Code → /mcp → memory should show Connected with 60+ tools.

Path A — native (Windows 10/11)

git clone https://github.com/vbcherepanov/total-agent-memory.git $HOME\total-agent-memory
cd $HOME\total-agent-memory
powershell -ExecutionPolicy Bypass -File install.ps1 -Ide claude-code

Same 9 steps as Unix, but:

• MCP config path is %USERPROFILE%\.claude\settings.json (or .cursor\mcp.json, etc.)
• Hooks copied to %USERPROFILE%\.claude\hooks\ — .ps1 versions (auto-capture, memory-trigger, user-prompt-submit, post-tool-use, pre-edit, on-bash-error, session-start/end, on-stop, codex-notify)
• Background services via Task Scheduler:
  • total-agent-memory-reflection — every 5 min (no native FileSystemWatcher equivalent)
  • total-agent-memory-orphan-backfill — daily 00:00 + 6h repetition
  • total-agent-memory-check-updates — weekly Mon 09:00
  • TotalAgentMemoryDashboard — AtLogon

Uninstall

All installers preserve ~/.tam/memory.db (legacy installs: ~/.claude-memory/memory.db) and your config files; only services + hook registrations are removed.

./install.sh --uninstall          # macOS/Linux/WSL2 — removes LaunchAgents OR systemd units
.\install.ps1 -Uninstall          # Windows — unregisters Scheduled Tasks + cleans settings.json

Diagnose

One-shot health check — prints ✓/✗ for each subsystem (OS detect, venv, MCP import, services, dashboard HTTP, Ollama, DB migrations):

bash scripts/diagnose.sh          # macOS / Linux / WSL2
.\scripts\diagnose.ps1            # Windows

Exit code 0 = all green, 1 = something broken.

Path B — Docker (everything containerized, cross-platform)

git clone https://github.com/vbcherepanov/total-agent-memory.git
cd total-agent-memory
bash install-docker.sh --with-compose

Brings up 5 services:

Service	Role	Exposed
mcp	MCP server (HTTP transport)	127.0.0.1:3737/mcp
dashboard	Web UI	127.0.0.1:37737
ollama	Local LLM runtime	127.0.0.1:11434
reflection	File-watch queue drainer	internal
scheduler	Ofelia cron (backfill + update check)	internal

First run pulls qwen2.5-coder:7b (~4.7 GB) + nomic-embed-text (~275 MB) — 5–10 min cold start.

GPU note: Docker Desktop on macOS doesn't forward Metal. Native install is faster on Mac. On Linux with NVIDIA Container Toolkit, uncomment the deploy.resources.reservations.devices block in docker-compose.yml.

Verify (both paths)

memory_save(content="install works", type="fact")
memory_stats()

Open http://127.0.0.1:37737/ — dashboard, knowledge graph, token savings.

---

Quick start

v11 default is MEMORY_MODE=fast. No LLM, no Ollama, no network in the save/search/recall hot path. To restore v10.5 synchronous-LLM behaviour set export MEMORY_MODE=deep. Mode switching: LAUNCH.md § Tuning.

Once installed, in any Claude Code / Codex CLI / Cursor session:

1. Resume where you left off (auto on session start, but you can also invoke)

session_init(project="my-api")
→ {summary: "yesterday: migrated auth middleware to JWT",
   next_steps: ["update OpenAPI spec", "notify frontend team"],
   pitfalls: ["don't revert migration 0042 — dev DB already migrated"]}

2. Save a decision (agent does this automatically after hooks are registered)

memory_save(
  type="decision",
  content="Chose pgvector over ChromaDB for multi-tenant RLS",
  context="WHY: single Postgres instance, per-tenant row-level security",
  project="my-api",
  tags=["database", "multi-tenant"],
)

3. Recall across sessions / projects

memory_recall(query="vector database choice", project="my-api", limit=5)
→ RRF-fused results from 6 retrieval tiers

4. Predict approach before starting a task

workflow_predict(task_description="migrate auth middleware to JWT-only")
→ {confidence: 0.82, predicted_steps: [...], similar_past: [...]}

5. Check a file's risk before editing (auto via hook, also manual)

file_context(path="/Users/me/my-api/src/auth/middleware.go")
→ {risk_score: 0.71, warnings: ["last 3 edits caused test failures in ..."], hot_spots: [...]}

6. Get full stats

memory_stats()
→ {sessions: 515, knowledge: {active: 1859, ...}, storage_mb: 119.5, ...}

---

CLI: lookup-memory for sub-agents

New in v9. Bash-friendly memory search for sub-agent workflows where launching the full MCP server would be overkill (e.g. Bash(lookup-memory "fix slow Wave query") from inside a Claude Code agent prompt).

Two equivalent commands ship with the package (registered as [project.scripts] entries — installed automatically by ./install.sh or ./update.sh):

lookup-memory "Caroline researched"          # human-readable bullets
tam-lookup "Caroline researched"             # short canonical alias
ctm-lookup "Caroline researched"             # legacy alias (v11.x and earlier)

lookup-memory --project myproj --limit 5 "auth flow"
lookup-memory --type solution --tag reusable "fix bug"
lookup-memory --json "claude code hooks"     # structured stdout for piping

How it works: opens the same $TAM_MEMORY_DIR/memory.db (legacy: $CLAUDE_MEMORY_DIR/memory.db) the running MCP server uses → BM25 ranking via FTS5 → falls back to LIKE on older DBs. Zero deps beyond the package. No Ollama, no rag_chat.py, no ChromaDB required for the CLI path. Works on macOS, Linux, Windows.

$ lookup-memory --project locomo_0 --limit 2 "adoption"
1. [synthesized_fact|locomo_0] Caroline is researching adoption agencies.
2. [synthesized_fact|locomo_0] Melanie congratulates Caroline on her adoption.

Why three names? lookup-memory matches the legacy bash script that older docs and sub-agent prompts reference (~/claude-memory-server/ollama/lookup_memory.sh, legacy install path). tam-lookup is the new project-prefixed canonical form (v12+). ctm-lookup is the v11.x prefixed name, kept as a legacy alias. All three call into total_agent_memory.lookup:main (v11.x and earlier: claude_total_memory.lookup:main, still importable via deprecation shim).

Migration note: v7/v8 docs that pointed at ~/claude-memory-server/ollama/lookup_memory.sh should be updated — the bash version still works for users with a manual install, but ./install.sh / ./update.sh clients on v9+ now get lookup-memory (and tam-lookup) on PATH directly via the package's [project.scripts] entry.

Token-efficient 3-layer workflow

When you only know the topic but not which records matter, use progressive disclosure:

1. Index — memory_recall(query="auth refactor", mode="index", limit=20) → ~2 KB of {id, title, score, type, project, created_at} per hit. No content, no cognitive expansion.
2. Timeline — memory_recall(query="auth refactor", mode="timeline", limit=5, neighbors=2) → top-K hits padded with ±neighbours from the same session, sorted chronologically.
3. Fetch — memory_get(ids=[3622, 3606]) → full content for ONLY the IDs you chose (max 50 per call, detail="summary" truncates to 150 chars).

Typical saving: 80-90 %% fewer tokens vs memory_recall(detail="full", limit=20) when you end up using 2-3 of the 20 hits.

Update

cd ~/total-agent-memory   # legacy clones: ~/claude-memory-server
./update.sh

7 stages:

1. Pre-flight — disk check + DB snapshot (keeps last 7)
2. Source pull (git) or SHA-256-verified tarball
3. Deps — pip install -r requirements.txt -r requirements-dev.txt (only if hash changed)
4. Full pytest suite — aborts with snapshot if red
5. Schema migrations — python src/tools/version_status.py
6. LaunchAgent reload — reflection + backfill + update-check
7. MCP reconnect notification — in-app /mcp → memory → Reconnect

Manual equivalent:

cd ~/total-agent-memory   # legacy clones: ~/claude-memory-server
git pull
.venv/bin/pip install -r requirements.txt -r requirements-dev.txt
.venv/bin/python src/tools/version_status.py
.venv/bin/python -m pytest tests/
# in Claude Code: /mcp → memory → Reconnect

Upgrading from v8.x to v9.0

v9 is backward compatible. Existing v8 calls and DB schema work unchanged — v9 is an infra release that adds pluggable backends, a public CLI for sub-agents, and LoCoMo benchmark wiring. Nothing is forcibly enabled.

One-command upgrade

cd ~/total-agent-memory && ./update.sh   # legacy clones: ~/claude-memory-server
# pulls v9 src, installs new entry-points (tam, tam-lookup, lookup-memory; legacy: ctm-lookup),
# keeps existing memory.db untouched.

After upgrade, verify the new CLI is on PATH:

lookup-memory --limit 1 "any-query-from-your-history"

What's new (no action required)

• lookup-memory / tam-lookup / ctm-lookup (legacy) CLI now installed alongside total-agent-memory MCP server (registered as [project.scripts] so ./install.sh and ./update.sh put them on PATH automatically). Sub-agent prompts that reference the legacy ~/claude-memory-server/ollama/lookup_memory.sh script keep working; new prompts should prefer the package-installed name.
• Embedding backends stay on fastembed by default. Switch via V9_EMBED_BACKEND=openai-3-large (set MEMORY_EMBED_API_KEY) — costs ~$0.10/5k rows for re-embed, expected R@5 lift on conversational data.
• Reranker backend stays on ce-marco by default. V9_RERANKER_BACKEND=bge-v2-m3 (or off) switches at runtime.
• Subject-aware retrieval is opt-in via --subject-aware in benchmarks/locomo_bench_llm.py. Future: surface as MCP tool flag.
• No migrations. Schema unchanged from v8.

What requires manual action

• Re-embed (only if switching embedding model, otherwise skip):

  python -m scripts.reembed --backend openai-3-large --confirm

• Old bash sub-agent prompts that hardcode ~/claude-memory-server/ollama/lookup_memory.sh "query" will keep working. To ride the new package install, replace with lookup-memory "query".

Breaking changes

None. All v8 MCP tools, env vars, hooks, and DB tables behave identically.

---

Upgrading from v7.x to v8.0

v8.0 is backward compatible — your existing v7 installation keeps working unchanged. All new features are opt-in via MCP tool calls or env vars.

One-command upgrade

cd ~/total-agent-memory && ./update.sh   # legacy clones: ~/claude-memory-server
# Applies migrations 011-013 idempotently, restarts LaunchAgents, updates dependencies

Then restart Claude Code: /mcp restart memory.

What changes automatically

• Migrations 011–013 apply on MCP startup (privacy_counters, task_phases, intents). Zero-downtime, idempotent.
• Existing memory_save calls keep working — they now additionally strip <private>...</private> sections if present.
• Existing memory_recall calls keep working — default mode is still "search". New mode="index" is opt-in.
• Existing session_end calls keep working — auto_compress=False by default. Pass auto_compress=True to opt in.
• Existing self_rules_context calls keep working — default returns all rules (no phase filter).

What requires manual setup

1. Cloud providers (only if you want to replace/augment Ollama):

export MEMORY_LLM_PROVIDER=openai       # or "anthropic"
export MEMORY_LLM_API_KEY=sk-...
export MEMORY_LLM_MODEL=gpt-4o-mini     # or "claude-haiku-4-5"

See Cloud providers for OpenRouter / per-phase routing / Cohere examples.

2. Install additional hooks (for UserPromptSubmit capture + citation):

./install.sh --ide claude-code   # re-run installer; it now registers user-prompt-submit.sh hook

The hook is additive — existing hooks keep working.

3. activeContext.md Obsidian integration (if you want markdown projection):

export MEMORY_ACTIVECONTEXT_VAULT=~/Documents/project/Projects   # default
# Disable: export MEMORY_ACTIVECONTEXT_DISABLE=1

Each session_end writes <vault>/<project>/activeContext.md.

Breaking changes

None. All v7 MCP tool signatures are preserved. New parameters are optional with safe defaults.

Embedding dimension note

If you switch to a cloud embedding provider (MEMORY_EMBED_PROVIDER=openai/cohere), the server will refuse to start if existing DB embeddings have a different dimension than the new provider returns. This is deliberate — it prevents silent data corruption.

Either:

• Keep MEMORY_EMBED_PROVIDER=fastembed (default 384d) and only change the LLM provider, OR
• Re-embed the DB: python src/tools/reembed.py --provider openai --model text-embedding-3-small

New MCP tools in v8.0

Quick reference — see full docs in MCP tools reference:

Tool	Purpose
classify_task(description)	Returns {level 1-4, suggested_phases, estimated_tokens}
task_create(task_id, description)	Starts state machine in "van" phase
phase_transition(task_id, new_phase, artifacts?)	Moves task through van/plan/creative/build/reflect/archive
task_phases_list(task_id)	Chronological phase history
save_decision(title, options, criteria_matrix, selected, rationale, ...)	Structured decision with per-criterion indexing
memory_get(ids, detail)	Batched full-content fetch for IDs from memory_recall(mode="index")
save_intent / list_intents / search_intents	UserPromptSubmit-captured prompts
rule_set_phase(rule_id, phase)	Tag a rule for phase-scoped loading

Extended tools:

• memory_recall(mode="index"|"timeline", decisions_only=False, ...) — 3-layer token-efficient workflow
• session_end(auto_compress=True, transcript=None, ...) — LLM-generated summary
• self_rules_context(phase="build"|"plan"|...) — phase filter
• save_knowledge(...) — now strips <private>...</private> sections automatically

Rollback plan

v8.0 doesn't remove any v7 functionality. If you hit an issue, you can:

1. Set env var to revert behaviour:

   export MEMORY_LLM_PROVIDER=ollama           # revert to local LLM
   export MEMORY_EMBED_PROVIDER=fastembed      # revert to local embeddings
   export MEMORY_ACTIVECONTEXT_DISABLE=1       # disable markdown projection
   export MEMORY_POST_TOOL_CAPTURE=0           # disable opt-in capture (default anyway)

2. Migrations 011/012/013 are additive (no DROP / ALTER on existing tables), so DB downgrade is not destructive — old code continues reading older tables.

3. Worst case: git checkout v7.0.0 && ./update.sh --skip-migrations.

---

Ollama setup (optional but recommended)

Without Ollama: works fully — raw content is saved, retrieval via BM25 + FastEmbed dense embeddings.

With Ollama: you also get LLM-generated summaries, keywords, question-forms, compressed representations, and deep enrichment (entities, intent, topics).

brew install ollama     # or: curl -fsSL https://ollama.com/install.sh | sh
ollama serve &
ollama pull qwen2.5-coder:7b        # default — best quality/speed on M-series
ollama pull nomic-embed-text        # optional, alternative embedder

Cloud providers (optional)

Use OpenAI, Anthropic, or any OpenAI-compat endpoint (OpenRouter, Together, Groq, DeepSeek, LM Studio, llama.cpp) instead of local Ollama.

OpenAI:

export MEMORY_LLM_PROVIDER=openai
export MEMORY_LLM_API_KEY=sk-...
export MEMORY_LLM_MODEL=gpt-4o-mini

Anthropic:

export MEMORY_LLM_PROVIDER=anthropic
export MEMORY_LLM_API_KEY=sk-ant-...
export MEMORY_LLM_MODEL=claude-haiku-4-5

OpenRouter (100+ models via one endpoint):

export MEMORY_LLM_PROVIDER=openai
export MEMORY_LLM_API_BASE=https://openrouter.ai/api/v1
export MEMORY_LLM_API_KEY=sk-or-...
export MEMORY_LLM_MODEL=anthropic/claude-haiku-4.5

Per-phase routing (cheap model for bulk, quality for compression):

export MEMORY_TRIPLE_PROVIDER=openai
export MEMORY_TRIPLE_MODEL=gpt-4o-mini
export MEMORY_ENRICH_PROVIDER=anthropic
export MEMORY_ENRICH_MODEL=claude-haiku-4-5

Embeddings (dimension must match existing DB or re-embed required):

export MEMORY_EMBED_PROVIDER=openai
export MEMORY_EMBED_MODEL=text-embedding-3-small  # 1536d
# or Cohere:
export MEMORY_EMBED_PROVIDER=cohere
export MEMORY_EMBED_API_KEY=...

Model choice

Model	Size	Use case
qwen2.5-coder:7b	4.7 GB	default — best quality/speed ratio

Configuration

Environment variables (all optional):

v11.0 — Memory mode + multi-embedding-space

Variable	Default	Purpose
MEMORY_MODE	fast	ultrafast|fast|balanced|deep. Selects hot-path profile. See Modes.
MEMORY_USE_LLM_IN_HOT_PATH	false	Master switch for sync LLM stages in save_knowledge / Recall.search. MEMORY_MODE=deep flips this to true.
MEMORY_ALLOW_OLLAMA_IN_HOT_PATH	false	Re-enables the silent FastEmbed → Ollama fallback ladder when FastEmbed is unavailable.
MEMORY_RERANK_ENABLED	false	Honour caller's rerank=true. When false, CrossEncoder rerank is hard-disabled even if a tool call requests it.
MEMORY_ENRICHMENT_ENABLED	false	Run the async enrichment worker. Default-ON in balanced / deep.
MEMORY_TEXT_EMBED_MODEL	sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2	Model for embedding_space=text.
MEMORY_CODE_EMBED_MODEL	empty → falls back to TEXT model	Model for embedding_space=code. The row still records space=code so a future swap is config-only.
MEMORY_LOG_EMBED_MODEL	empty → TEXT	Model for embedding_space=log.
MEMORY_CONFIG_EMBED_MODEL	empty → TEXT	Model for embedding_space=config.
MEMORY_DEFAULT_EMBEDDING_SPACE	text	Space for unclassified content.

v10 + earlier

Variable	Default	Purpose
MEMORY_DB	~/.tam/memory.db (legacy installs: ~/.claude-memory/memory.db)	SQLite location
MEMORY_LLM_ENABLED	auto	auto|true|false|force — LLM enrichment toggle
MEMORY_LLM_MODEL	qwen2.5-coder:7b	Ollama model for enrichment
MEMORY_LLM_PROBE_TTL_SEC	60	Cache TTL for Ollama availability probe
MEMORY_LLM_TIMEOUT_SEC	60	Global fallback timeout for Ollama requests (s)
MEMORY_TRIPLE_TIMEOUT_SEC	30	Timeout for deep triple extraction (s)
MEMORY_ENRICH_TIMEOUT_SEC	45	Timeout for deep enrichment (s)
MEMORY_REPR_TIMEOUT_SEC	60	Timeout for representation generation (s)
MEMORY_TRIPLE_MAX_PREDICT	2048	num_predict cap for triple extraction
OLLAMA_URL	http://localhost:11434	Ollama endpoint
MEMORY_EMBED_MODE	fastembed	fastembed|sentence-transformers|ollama
DASHBOARD_PORT	37737	HTTP dashboard port
MEMORY_MCP_PORT	3737	HTTP MCP transport port (Docker path)
MEMORY_ASYNC_ENRICHMENT	false	v10.1 — move quality gate / contradiction / entity dedup / episodic / wiki to a background worker. See Performance tuning
MEMORY_ENRICH_TICK_SEC	0.1	Worker tick interval (clamp 0.01..5)
MEMORY_ENRICH_BATCH	5	Rows claimed per tick (clamp 1..50)
MEMORY_ENRICH_MAX_ATTEMPTS	3	Retries before flipping a row to failed
MEMORY_ENRICH_STALE_AFTER_SEC	60	Seconds before a processing row is reclaimed (worker crash recovery)

CPU-only / WSL hosts: if Ollama keeps timing out, lower MEMORY_TRIPLE_MAX_PREDICT before raising timeouts. install-codex.sh writes conservative defaults automatically. For 30-40s save latency on WSL2 → set MEMORY_ASYNC_ENRICHMENT=true — see below.

Full config: see total_agent_memory/config.py.

Performance tuning

v11.0 fast-mode hot path (default)

When MEMORY_MODE=fast (default):

metric	p50	p95	p99
save_fast	6.2	8.9	11.4
save_fast cached	0.3	0.4	1.4
search_fast	3.4	4.7	6.0
cached_search	3.1	3.4	3.6

llm_calls=0, network_calls=0. Reproduce: ./bin/memory-bench. Regression gate: ./bin/memory-perf-gate. Architecture rationale and per-stage audit: docs/v11/audit.md. Raw bench artifact: docs/v11/benchmark.md.

If your numbers do not match the table, run ./bin/memory-bench --warmup first — cold FastEmbed import dominates the first call.

Legacy: v10.5 deep-mode memory_save latency

The synchronous v10 hot path runs five LLM-bound stages inline so a drop verdict can block the INSERT and a contradiction supersede commits in the same transaction. On macOS with a warm Ollama that's ~340 ms median; on a WSL2 box without GPU/CoreML each LLM round-trip can stretch the same call into 30–40 seconds.

v10.1 ships an opt-in inbox/outbox worker that moves the heavy stages out of band:

sync   : privacy → canonical_tags → INSERT → embed → enqueue → return
worker : quality_gate → entity_dedup_audit → contradiction → episodic → wiki

Enable it in your env:

export MEMORY_ASYNC_ENRICHMENT=true
# Optional knobs (defaults shown):
export MEMORY_ENRICH_TICK_SEC=0.1
export MEMORY_ENRICH_BATCH=5
export MEMORY_ENRICH_MAX_ATTEMPTS=3
export MEMORY_ENRICH_STALE_AFTER_SEC=60

Restart the MCP server. A background daemon thread now consumes enrichment_queue; you can watch it on the dashboard panel ⚡ v10.1 enrichment worker.

Bench v10.5 (10-record corpus × 2 rounds, with LLM stages on)

memory_save latency:

	min	p50	p95	p99	max	mean
sync (default)	17.5 ms	25.3 ms	2150.5 ms	2179.0 ms	2186.1 ms	348.0 ms
async (MEMORY_ASYNC_ENRICHMENT=true)	18.1 ms	22.3 ms	26.7 ms	27.4 ms	27.5 ms	22.7 ms

memory_recall latency: p50 ≈ 3-5 ms in both modes (steady state), with cold-cache p95 outliers on the first warmup hit.

p95 collapses 80× with async (2150 ms → 27 ms). On WSL2 with a slow Ollama, the same shape holds — sync p95 of 30-40 s becomes async p95 of ~300-1000 ms (LLM moves out of the hot path entirely).

Reproduce: ./.venv/bin/python benchmarks/v10_5_latency.py --rounds 2 --with-llm. Full report: benchmarks/v10_5_results.md.

Trade-off — soft drop semantic

When async is on, a quality_gate drop no longer prevents the INSERT (we already committed in the sync path). Instead the row is marked status='quality_dropped' after the worker scores it. memory_recall ignores that status (idx_knowledge_status_quality is added in migration 020). Audit history stays in quality_gate_log so nothing is lost.

If you need strict pre-INSERT gating (e.g. compliance), keep the default sync path.

Crash recovery

Rows stuck in processing longer than MEMORY_ENRICH_STALE_AFTER_SEC (default 60 s) are flipped back to pending automatically — covers worker process kills mid-stage. The pre-existing write_intents outbox still covers a crash before INSERT.

Roadmap

Shipped in v11.0 (2026-04-27) — production memory engine

• ✅ Default MEMORY_MODE=fast — zero LLM, zero Ollama, zero network in save/search/recall hot path. Set MEMORY_MODE=deep to restore v10.5 behaviour.
• ✅ Memory Core / AI Layer split — src/memory_core/* is deterministic; src/ai_layer/* owns every LLM-bound code path. Enforced by tests/test_no_llm_hot_path.py.
• ✅ 4 modes: ultrafast / fast / balanced / deep. Single env flag.
• ✅ Multi-embedding-space contract — every vector row records provider / model / dimension / space / content_type / language. Spaces: text / code / log / config. Single Chroma backend; per-space model swap is config-only.
• ✅ Embed fallback ladder gated — silent Ollama fallback in Store.embed requires MEMORY_ALLOW_OLLAMA_IN_HOT_PATH=true.
• ✅ New MCP tools: memory_save_fast, memory_search_fast, memory_explain_search, memory_warmup, memory_perf_report, memory_rebuild_fts, memory_rebuild_embeddings, memory_eval_locomo, memory_eval_recall, memory_eval_temporal, memory_eval_entity_consistency, memory_eval_contradictions, memory_eval_long_context.
• ✅ Migrations 021 (embedding_spaces) + 022 (embedding_cache_v11) — idempotent on next start.
• ✅ Benchmark suite: bin/memory-bench (artifact docs/v11/benchmark.md) + bin/memory-perf-gate for CI.

Shipped in v10.5 (2026-04-27)

• ✅ Universal memory-protocol skill — single canonical SKILL.md + 4 references (tool cheatsheet for all 60+ MCP tools, workflow recipes for 15 common situations, hooks reference, per-IDE setup) + 4 templates (Claude Code settings.json, Codex config.toml, Cursor .mdc, Cline .md). Same content for every IDE; only the wiring differs.
• ✅ install.sh --ide extended to 9 IDEs: claude-code, codex, cursor, cline, continue, aider, windsurf, gemini-cli, opencode. New helpers: register_mcp_cline / continue / aider / windsurf + _json_merge_mcp_nested for the dotted-key case (cline.mcpServers).
• ✅ Cross-platform hardening — all bash scripts pass bash -n under macOS bash 3.2 (default). Replaced ${var,,} lowercase bashism in update.sh with tr '[:upper:]' '[:lower:]'. Verified with shellcheck.
• ✅ Sub-agent memory protocol — universal header for any sub-agent (php-pro, golang-pro, vue-expert, etc.) with mandatory memory_recall before / memory_save after. Full template in skills/memory-protocol/references/subagent-protocol.md.
• ✅ v10.5 latency benchmark — benchmarks/v10_5_latency.py with apples-to-apples sync vs async comparison. Demonstrates 80× p95 reduction (2150 ms → 27 ms) when async is enabled with LLM stages on.

Shipped in v10.1 (2026-04-27)

• ✅ Async enrichment worker — opt-in MEMORY_ASYNC_ENRICHMENT=true moves quality gate / entity dedup / contradiction detector / episodic linking / wiki refresh to a background thread. Drops max save latency 5.4× on macOS, 60–100× on WSL2. See Performance tuning.
• ✅ enrichment_queue table with stale-processing recovery (rows stuck >60 s in processing flip back to pending).
• ✅ Dashboard panel for worker health: depth, throughput/min, p50/p95 ms per task, oldest pending age, recent failures.
• ✅ _binary_search ValueError fix — np.argpartition requires kth STRICTLY < N; tiny test projects (pool ≤ 50) used to silently break contradiction_log.
• ✅ coref_resolver RU→EN translation fix — prompt explicitly pins output language (Do NOT translate).

Shipped in v10.0 (2026-04-27)

• ✅ 10 Beever-Atlas-inspired features in one push: quality gate (Beever 6-Month Test), canonical tag vocabulary, importance boost in recall, opt-in coref resolution, contradiction auto-detection with supersede, write-intent outbox + reconciler, embedding-based entity dedup, episodic save events in the graph, smart query router (relational vs lexical), per-project Markdown wiki digest.
• ✅ 5 SQLite migrations (015–019) applied automatically on restart.
• ✅ 11 new env knobs, all with safe fail-open defaults.
• ✅ Tests: 971 → 1124 (+153).

Shipped in v9.0 (2026-04-25)

• ✅ lookup-memory / tam-lookup / ctm-lookup (legacy) CLI — bash entry-point for sub-agents, registered as [project.scripts] and installed by ./install.sh / ./update.sh (replaces manual ~/claude-memory-server/ollama/lookup_memory.sh)
• ✅ Pluggable embedding backends: openai-3-small, openai-3-large (3072d), bge-m3, e5-large, locomo-tuned-minilm (fine-tuned on user data)
• ✅ Pluggable reranker backends: ce-marco, bge-v2-m3, bge-large, off (env V9_RERANKER_BACKEND, hot-swap)
• ✅ Subject-aware retrieval — LLM extracts (subject, action) from question → SQL graph lookup → DIRECT FACTS prepended to context (LoCoMo cat 1/2 lift)
• ✅ Judge-weighted ensemble — category-aware scoring rubric + abstain logic for LoCoMo-style adversarial gold
• ✅ Fine-tune embedding pipeline (scripts/finetune_embedding.py) — mine triplets from your data, train on top of MiniLM via sentence-transformers
• ✅ Few-shot pair mining (scripts/mine_locomo_fewshot.py) — augment per-category prompts with held-in (Q,A) pairs
• ✅ Schema-specific graph extractor (closed canonical predicate vocabulary, optional)
• ✅ SSL fix for macOS Python.org installs — urllib requests now use certifi by default
• ✅ HTTP retry with exponential backoff for embedding providers (5xx/timeout)
• ✅ LoCoMo benchmark integration (benchmarks/locomo_bench_llm.py with 14 ablation flags)

Shipped in v8.0 (2026-04-19)

• ✅ Task workflow phases (L1-L4 classifier + 6-phase state machine)
• ✅ Structured save_decision with criteria matrix + multi-representation criterion indexing
• ✅ Cloud LLM/embed providers (OpenAI, Anthropic, Cohere, any OpenAI-compat)
• ✅ session_end(auto_compress=True) via LLM provider
• ✅ Progressive disclosure: memory_recall(mode="index") + memory_get(ids)
• ✅ activeContext.md Obsidian live-doc projection
• ✅ Phase-scoped rules via tag filter
• ✅ <private>...</private> inline redaction
• ✅ HTTP citation endpoints /api/knowledge/{id} + /api/session/{id}
• ✅ UserPromptSubmit + PostToolUse (opt-in) capture hooks
• ✅ Unified install.sh --ide {claude-code|cursor|gemini-cli|opencode|codex}

Planned (v8.1+)

• Plugin marketplace publish (when Claude Code API opens)
• has_llm() per-phase provider caching
• GitHub Actions: install smoke tests + LongMemEval nightly

Under research

• "Endless mode" — continuous session without hard boundaries (virtual sessions by idle >N hours)
• MLX local LLM integration (A1 plan from memory #3583)
• Speculative decoding for local path (+1.5-1.8× LLM speed)

---

Contributing

• Open an issue before a large PR — saves everyone time.
• pytest tests/ must stay green. Add tests for new tools.
• Update evals/scenarios/*.json if you change retrieval behavior.
• Docs-only / typo PRs welcome without discussion.
