+
+This file provides context for AI coding assistants (Claude Code, Cursor, GitHub Copilot, Codex, etc.) working with the Mem0 repository.
+
+## Project Overview
+
+**Mem0** ("mem-zero") is an intelligent memory layer for AI agents and assistants. It provides persistent, personalized memory via both a hosted platform API and self-hosted open-source SDKs.
+
+- **Repository**: https://github.com/mem0ai/mem0
+- **Documentation**: https://docs.mem0.ai
+- **License**: Apache-2.0
+
+## Repository Structure
+
+This is a **polyglot monorepo** containing Python and TypeScript packages, CLIs, servers, plugins, documentation, and evaluation tooling.
+
+### Key Directories
+
+| Directory | Description |
+|-----------|-------------|
+| `mem0/` | Core Python SDK (`mem0ai` on PyPI) — memory, LLMs, embeddings, vector stores, graphs, rerankers |
+| `mem0-ts/` | TypeScript SDK (`mem0ai` on npm) — client + OSS memory |
+| `cli/python/` | Python CLI (`mem0-cli` on PyPI) — Typer-based, entry point `mem0` |
+| `cli/node/` | Node CLI (`@mem0/cli` on npm) — Commander-based, entry point `mem0` |
+| `vercel-ai-sdk/` | `@mem0/vercel-ai-provider` — Vercel AI SDK memory provider |
+| `openclaw/` | `@mem0/openclaw-mem0` — OpenClaw plugin for Claude Code / AI editors |
+| `server/` | FastAPI REST server for self-hosted Mem0 (Docker: FastAPI + PostgreSQL/pgvector + Neo4j) |
+| `openmemory/` | Self-hosted memory platform — `api/` (FastAPI + Alembic + MCP server) and `ui/` (Next.js 15 + React 19) |
+| `mem0-plugin/` | AI editor plugins (Claude Code, Cursor, Codex) — MCP server connection, lifecycle hooks, skills |
+| `skills/` | Claude Code skill definitions — `mem0/`, `mem0-cli/`, `mem0-vercel-ai-sdk/` |
+| `docs/` | Documentation site (Mintlify) |
+| `tests/` | Python SDK tests (pytest) |
+| `evaluation/` | Benchmarking framework — LOCOMO evals, experiment runner, score generation |
+| `examples/` | Sample projects — demo apps, Chrome extension, multi-agent patterns |
+| `cookbooks/` | Jupyter notebooks — customer support chatbot, AutoGen integration |
+| `embedchain/` | Legacy Embedchain RAG framework (maintained separately, Poetry-based) |
+| `pr-reviews/` | Pull request review materials |
+| `scripts/` | Repo-wide utility scripts (e.g., `check-llms-txt-coverage.py` for docs/llms.txt sync) |
+

+
+## Development Setup
+
+### Requirements
+
+- **Python**: 3.9+ (3.10+ for CLI)
+- **Node.js**: v18+ (v20 or v22 recommended)
+- **pnpm**: v10+ (`npm install -g pnpm@10`) — used for all TypeScript packages
+- **Hatch**: Python build/environment tool (`pip install hatch`)
+- **Docker**: Required for `server/` and `openmemory/` development
+
+### Initial Setup
+
+```bash
+# Python SDK
+hatch shell dev_py_3_11           # creates environment with all deps
+pre-commit install                # install git hooks
+
+# TypeScript packages
+cd mem0-ts && pnpm install        # TS SDK
+cd cli/node && pnpm install       # Node CLI
+cd vercel-ai-sdk && pnpm install  # Vercel AI provider
+cd openclaw && pnpm install       # OpenClaw plugin
+```
+
+## Build, Lint, and Test Commands
+
+### Python SDK (`mem0/`)
+
+```bash
+# Environment setup (uses Hatch)
+hatch shell dev_py_3_11           # or dev_py_3_9, dev_py_3_10, dev_py_3_12
+
+# Linting and formatting
+make lint                          # ruff check
+make format                        # ruff format
+make sort                          # isort mem0/
+
+# Tests
+make test                          # pytest tests/
+make test-py-3.9                   # test specific Python version (3.9–3.12)
+
+# Build and publish
+make build                         # hatch build
+make publish                       # hatch publish

+## Core APIs
+
+### Python
+
+| Function / Class | Purpose | Import |
+|-----------------|---------|--------|
+| `Memory` | Self-hosted memory (sync) | `from mem0 import Memory` |
+| `AsyncMemory` | Self-hosted memory (async) | `from mem0 import AsyncMemory` |
+| `MemoryClient` | Hosted platform client (sync) | `from mem0 import MemoryClient` |
+| `AsyncMemoryClient` | Hosted platform client (async) | `from mem0 import AsyncMemoryClient` |
+
+**Key `Memory` / `MemoryClient` methods:**
+
+| Method | Purpose |
+|--------|---------|
+| `add(messages, *, user_id, agent_id, run_id, metadata)` | Store a new memory |
+| `search(query, *, user_id, agent_id, run_id, limit, filters)` | Search memories |
+| `get(memory_id)` | Retrieve a single memory by ID |
+| `get_all(*, user_id, agent_id, run_id, limit)` | List all memories |
+| `update(memory_id, data)` | Update a memory |
+| `delete(memory_id)` | Delete a memory |
+| `delete_all(*, user_id, agent_id, run_id)` | Delete all memories |
+| `history(memory_id)` | Get change history for a memory |
+
+### TypeScript
+
+| Export | Purpose | Import |
+|--------|---------|--------|
+| `MemoryClient` | Hosted platform client | `import { MemoryClient } from 'mem0ai'` |
+| `Memory` | Self-hosted OSS memory | `import { Memory } from 'mem0ai/oss'` |
+
+## Import Patterns
+
+### Python
+
+| What | Import |
+|------|--------|
+| Core memory classes | `from mem0 import Memory, AsyncMemory` |
+| Platform client | `from mem0 import MemoryClient, AsyncMemoryClient` |
+| Configuration | `from mem0.configs.base import MemoryConfig` |
+| LLM providers | `from mem0.llms.<provider> import <ProviderLLM>` |
+| Embedding providers | `from mem0.embeddings.<provider> import <ProviderEmbedding>` |
+| Vector store providers | `from mem0.vector_stores.<provider> import <ProviderVectorStore>` |
+
+### TypeScript
+
+| What | Import |
+|------|--------|
+| Hosted client | `import { MemoryClient } from 'mem0ai'` |
+| OSS memory | `import { Memory } from 'mem0ai/oss'` |
+| Specific providers (OSS) | `import { OpenAIEmbedding } from 'mem0ai/oss'` |
+
+## Coding Standards
+
+### File Naming Conventions
+
+- **Python source files:** `snake_case.py` (e.g., `azure_openai.py`, `cohere_reranker.py`)
+- **Python test files:** `test_<module>.py` (e.g., `test_memory.py`, `test_main.py`)
+- **TypeScript source files:** `snake_case.ts` (e.g., `azure_ai_search.ts`)
+- **TypeScript test files:** `<module>.test.ts` (e.g., `memory.test.ts`)
+- **Config/manifest files:** `kebab-case` (e.g., `openclaw.plugin.json`, `jest.config.js`)
+
+### Python Conventions
+
+- **Provider pattern:** All providers (LLMs, embeddings, vector stores, graphs, rerankers) inherit from a `base.py` abstract class in their directory. Config classes live in `configs.py`.
+- **Pydantic v2** for all data models and configuration.
+- **Ruff** is the single linting and formatting tool — no black, no flake8.
+  - Root SDK: line length **120**
+  - Python CLI: line length **100** with extended rule set (UP, B, SIM, RUF)
+- **isort** with `profile = "black"` for import sorting.
+- Ruff excludes `embedchain/` and `openmemory/` from root config.
+
+### TypeScript Conventions
+
+- **Build:** tsup across all packages.
+- **Package manager:** pnpm everywhere (no npm, no yarn).
+- **TypeScript strict mode** across all packages.
+- **Linting varies by package:**
+
+| Package | Linter | Formatter | Test Framework |
+|---------|--------|-----------|---------------|
+| `mem0-ts/` | — | Prettier | jest |
+| `cli/node/` | Biome | Biome | vitest |
+| `vercel-ai-sdk/` | ESLint | Prettier | jest + vitest |
+| `openclaw/` | — | — | vitest |
+
+### Type Checking
+
+Always run type checking after modifying TypeScript code:
+
+```bash
+cd <package> && pnpm run typecheck    # or: tsc --noEmit
+```
+
+## Architecture
+
+### Provider Pattern
+
+The SDK uses a consistent plugin architecture across 5 categories. Each category has a `base.py` abstract class and concrete provider implementations:
+
+| Category | Count | Examples |
+|----------|-------|---------|
+| **LLMs** | 24 | OpenAI, Anthropic, AWS Bedrock, Azure OpenAI, Gemini, Groq, Ollama, Together, DeepSeek, vLLM, LiteLLM, LM Studio, xAI |
+| **Vector Stores** | 30 | Qdrant, Pinecone, Chroma, Weaviate, Milvus, MongoDB, Redis, Elasticsearch, pgvector, Supabase, Faiss, S3 Vectors |
+| **Embeddings** | 15 | OpenAI, Azure OpenAI, Gemini, HuggingFace, FastEmbed, Together, AWS Bedrock, Ollama, Vertex AI |
+| **Graph Stores** | 4 | Neo4j, Memgraph, Kuzu, Apache AGE |
+| **Rerankers** | 5 | Cohere, HuggingFace, LLM-based, Sentence Transformer, Zero Entropy |
+
+### Two Usage Modes
+
+Self-hosted `Memory` / `AsyncMemory` classes and hosted-platform `MemoryClient` — both in Python and TypeScript.
+
+### Graph Memory
+
+Optional layer on top of vector memory for relationship-aware retrieval. Configured via the `graph` section of `MemoryConfig`.
+
+### MCP Integration
+
+Model Context Protocol support in multiple places:
+
+- **Remote:** MCP server at `mcp.mem0.ai`
+- **Local:** MCP server in `openmemory/api/` (FastAPI-based)
+- **Plugin:** MCP tools in `mem0-plugin/` — 9 tools: `add_memory`, `search_memories`, `get_memories`, `get_memory`, `update_memory`, `delete_memory`, `delete_all_memories`, `delete_entities`, `list_entities`
+
+### Plugin & Skills System
+
+- `mem0-plugin/` provides integrations for Claude Code, Cursor, and Codex via MCP server connections and lifecycle hooks for automatic memory capture.
+- `skills/` contains structured skill definitions for AI agents, covering SDK usage, CLI workflows, and Vercel AI SDK patterns.
+
+### Adding a New Provider
+
+To add a new LLM, embedding, vector store, or reranker provider:
+
+1. Create `mem0/<category>/<provider_name>.py`
+2. Inherit from the abstract base class in `mem0/<category>/base.py`
+3. Add configuration to `mem0/<category>/configs.py` (if the category uses one)
+4. Register the provider in `mem0/<category>/__init__.py`
+5. Add tests in `tests/<category>/<provider_name>/`
+6. Add any new dependencies to the appropriate optional group in `pyproject.toml` (never to core `dependencies`)
+7. Follow the exact pattern of existing providers in the same category — match method signatures, error handling, and config structure
+
+## CI/CD
+
+### CI Workflows (automated testing)
+
+| Workflow | File | Triggers | Tests |
+|----------|------|----------|-------|
+| Python SDK | `ci.yml` | Push to main, PRs on `mem0/`, `tests/`, `pyproject.toml` | Ruff lint + pytest on Python 3.10, 3.11, 3.12 |
+| TypeScript SDK | `ts-sdk-ci.yml` | Push to main, PRs on `mem0-ts/` | Prettier + build + jest on Node 20, 22 |
+| Python CLI | `cli-python-ci.yml` | Push to `cli/python/`, PRs, manual | Ruff lint + pytest + hatch build on Python 3.10, 3.11, 3.12 |
+| Node CLI | `cli-node-ci.yml` | Push to `cli/node/`, PRs, manual | Biome lint + tsc + vitest + tsup build on Node 20, 22 |
+| OpenClaw | `openclaw-checks.yml` | Push to `openclaw/`, PRs, manual | tsc + vitest (with Codecov) + tsup build on Node 20, 22 |
+| Embedchain | `ci.yml` (shared) | PRs on `embedchain/` | Ruff + pytest + coverage on Python 3.9–3.12 |
+
+### CD Workflows (automated publishing)
+
+| Workflow | File | Tag Prefix | Target |
+|----------|------|------------|--------|
+| Python SDK | `cd.yml` | `v*` | PyPI (`mem0ai`) |
+| TypeScript SDK | `ts-sdk-cd.yml` | `ts-v*` | npm (`mem0ai`) |
+| Python CLI | `cli-python-cd.yml` | `cli-v*` | PyPI (`mem0-cli`) |
+| Node CLI | `cli-node-cd.yml` | `cli-node-v*` | npm (`@mem0/cli`) |
+| Vercel AI SDK | `vercel-ai-cd.yml` | `vercel-ai-v*` | npm (`@mem0/vercel-ai-provider`) |
+| OpenClaw | `openclaw-cd.yml` | `openclaw-v*` | npm (`@mem0/openclaw-mem0`) |
+
+- All publishing uses **OIDC trusted publishing** — no tokens or secrets required.
+- First publish of a new npm package must be done manually; OIDC works for subsequent versions.
+
+### Utility Workflows
+
+| Workflow | File | Purpose |
+|----------|------|---------|
+| Issue Labeler | `issue-labeler.yml` | Automatic issue labeling |
+| Stale Bot | `stale.yml` | Marks stale issues and PRs |
+| llms.txt Check | `docs-llms-txt-check.yml` | Blocks PRs touching `docs/**/*.mdx` when `docs/llms.txt` is out of sync. Fix locally with `python scripts/check-llms-txt-coverage.py --write`. |
+
+## Task Completion Guidelines
+
+These guidelines outline typical artifacts for different task types. Use judgment to adapt based on scope and context.
+
+### Bug Fixes
+
+1. **Unit tests**: Add tests that would fail without the fix (regression tests)
+2. **Implementation**: Fix the bug
+3. **Manual verification**: Run the relevant test suite to confirm the fix
+4. **Lint**: Run the appropriate linter for the package you modified
+
+### New Features
+
+1. **Implementation**: Build the feature following existing patterns
+2. **Unit tests**: Comprehensive test coverage for new functionality
+3. **Documentation**: Update relevant docs in `docs/` for public APIs
+4. **Examples**: Add usage examples if the feature introduces new user-facing behavior
+5. **llms.txt**: Any new `.mdx` page under `docs/` must be linked in `docs/llms.txt` with a scope tag (`[Platform]` / `[OSS]` / `[Both]`) and a `Use when ...` description. The `docs-llms-txt-check.yml` workflow runs on every PR that touches docs and **fails the check** if the index is out of sync. To fix: run `python scripts/check-llms-txt-coverage.py --write` locally to scaffold placeholders under `## Unclassified - needs triage`, then replace the `[TODO: ...]` tags, rewrite descriptions as `Use when ...`, move entries into the right section, and delete the triage heading when empty.
+
+### New Provider (LLM / Embedding / Vector Store / Reranker)
+
+1. **Implementation**: Follow the "Adding a New Provider" steps above
+2. **Tests**: Add unit tests matching the pattern of existing providers
+3. **Configuration**: Add to the appropriate `configs.py` and `__init__.py`
+4. **Dependencies**: Add to the correct optional group in `pyproject.toml`
+5. **Documentation**: Add an integration guide in `docs/integrations/`
+
+### Refactoring / Internal Changes
+
+- Unit tests for any changed behavior
+- No documentation needed for internal-only changes
+- Ensure all existing tests still pass
+
+### When to Deviate
+
+These are guidelines, not rigid rules. Adjust based on:
+
+- **Scope**: Trivial fixes (typos, comments) may not need tests
+- **Visibility**: Internal changes may not need documentation
+- **Context**: Some changes span multiple categories — use judgment
+
+When uncertain about expected artifacts, ask for clarification.
+
+## Contributing Guidelines
+
+### Workflow
+
+1. Fork and clone the repository.
+2. Create a feature branch from `main` (e.g., `feature/my-new-feature`).
+3. Make your changes — add tests, docs, and examples as appropriate.
+4. Run linting and tests for every package you modified (see commands above).
+5. Run `pre-commit install` on first setup — hooks run ruff + isort automatically.
+6. Commit with a clear message following [Conventional Commits](https://www.conventionalcommits.org/) (e.g., `feat:`, `fix:`, `docs:`, `refactor:`).
+7. Push and open a Pull Request against `main`.
+
+### Pull Request Requirements
+
+Every PR must follow the repo's PR template (`.github/PULL_REQUEST_TEMPLATE.md`):
+
+1. **Linked Issue** — Reference the issue with `Closes #<number>`. If no issue exists, create one first or explain why in the description.
+2. **Description** — Explain what the PR does and why it's needed.
+3. **Type of Change** — Check the appropriate box:
+   - Bug fix / New feature / Breaking change / Refactor / Documentation update
+4. **Breaking Changes** — If applicable, describe what breaks and the migration path.
+5. **Test Coverage** — Check what applies:
+   - Added/updated unit tests
+   - Added/updated integration tests
+   - Tested manually (describe how)
+   - No tests needed (explain why)
+6. **Checklist** — All must be checked before merge:
+   - [ ] Code follows the project's style guidelines
+   - [ ] Self-review performed
+   - [ ] Tests added that prove the fix/feature works
+   - [ ] New and existing tests pass locally
+   - [ ] Documentation updated if needed
+

+```
+
+### General Rules
+
+- Follow existing code patterns — don't introduce new frameworks or abstractions without discussion.
+- Version bumps go in `pyproject.toml` (Python) or `package.json` (TypeScript).
+- For `server/` and `openmemory/` work, use Docker Compose for local development.
+- Do NOT use `pip` or `conda` for dependency management — use `hatch` (see `docs/contributing/development.mdx`).
+
+### Contributing Guides
+
+| Task | Guide |
+|------|-------|
+| Code contributions | `docs/contributing/development.mdx` |
+| Documentation contributions | `docs/contributing/documentation.mdx` |
+| PR template | `.github/PULL_REQUEST_TEMPLATE.md` |
+| Bug reports | `.github/ISSUE_TEMPLATE/bug_report.yml` |
+| Feature requests | `.github/ISSUE_TEMPLATE/feature_request.yml` |
+| Documentation issues | `.github/ISSUE_TEMPLATE/documentation_issue.yml` |
+
+## Do NOT
+
+- Modify CI/CD workflows without explicit approval.
+- Add new Python dependencies to the core `dependencies` list in `pyproject.toml` without discussion — use optional dependency groups instead.
+- Commit `.env` files, API keys, or credentials.
+- Modify `embedchain/` unless specifically working on that package — it has its own build system (Poetry).
+- Skip pre-commit hooks.
+- Use npm or yarn in TypeScript packages — this repo uses pnpm exclusively.
+- Use `require()` for imports in TypeScript — use ES module `import` syntax.
+- Mix up linter configs: root Python SDK uses line-length 120, Python CLI uses 100, Node CLI uses Biome (not ESLint/Ruff).
+- Modify `openmemory/` database migrations without understanding the Alembic migration chain.
+- Change public APIs without updating documentation in `docs/`.

+## New Memory Algorithm (April 2026)
 
-##  🔥 Research Highlights
-- **+26% Accuracy** over OpenAI Memory on the LOCOMO benchmark
-- **91% Faster Responses** than full-context, ensuring low-latency at scale
-- **90% Lower Token Usage** than full-context, cutting costs without compromise
+| Benchmark | Old | New  | Tokens  | Latency p50  |
+| --- | --- | --- | --- | --- |
+| **LoCoMo** | 71.4 | **91.6** | 7.0K  | 0.88s  |
+| **LongMemEval** | 67.8 | **93.4** | 6.8K  | 1.09s  |
+| **BEAM (1M)** | — | **64.1** | 6.7K  | 1.00s  |
+| **BEAM (10M)** | — | **48.6** | 6.9K  | 1.05s  |
+
+All benchmarks run on the same production-representative model stack. Single-pass retrieval (one call, no agentic loops).
+
+**What changed:**
+- **Single-pass ADD-only extraction** -- one LLM call, no UPDATE/DELETE. Memories accumulate; nothing is overwritten.
+- **Agent-generated facts are first-class** -- when an agent confirms an action, that information is now stored with equal weight.
+- **Entity linking** -- entities are extracted, embedded, and linked across memories for retrieval boosting.
+- **Multi-signal retrieval** -- semantic, BM25 keyword, and entity matching scored in parallel and fused.
+
+See the [migration guide](https://docs.mem0.ai/migration/oss-v2-to-v3) for upgrade instructions. The [evaluation framework](https://github.com/mem0ai/memory-benchmarks) is open-sourced so anyone can reproduce the numbers.
+
+## Research Highlights
+- **91.6 on LoCoMo** -- +20 points over the previous algorithm
+- **93.4 on LongMemEval** -- +26 points, with +53.6 on assistant memory recall
+- **64.1 on BEAM (1M)** -- production-scale memory evaluation at 1M tokens

+### Why `--json`/`--agent` global flags exist
+
+The `--json` and `--agent` flags (aliases of each other) activate agent mode globally. When set:
+1. All output becomes a structured JSON envelope (`{status, command, duration_ms, scope, count, data}`).
+2. The `data` field is sanitized via `sanitizeAgentData` — only the most relevant fields are included per command, reducing noise for agents parsing the output.
+3. All human-readable output (spinners, colors, banners, timing lines) is suppressed.
+4. Errors are emitted as JSON to stdout with a non-zero exit code, not to stderr as text.
+
+This is distinct from `--output json`, which returns the raw API response without sanitization.
+
 ### Why `--output json` is on every command
 
 Every data-returning command supports `--output json` (or `--json` for `help`). This enables machine consumption by AI agents and scripts. JSON output goes to stdout while human-readable spinners/timing go to stderr, so piping `mem0 list -o json | jq .` works cleanly.

+
+```bash
+mem0 --agent search "user preferences" --user-id alice
+mem0 --agent add "User prefers dark mode" --user-id alice
+mem0 --agent list --user-id alice

+
+What agent mode does differently from `--output json`:
+- **Sanitized `data`**: only the fields an agent needs (id, memory, score, etc.) — no internal API noise
+- **No human output**: spinners, colors, and banners are suppressed entirely
+- **Errors as JSON**: errors go to stdout as `{"status": "error", "command": "...", "error": "..."}` with a non-zero exit code

+## Commands
+
+### `mem0 init`
+
+Interactive setup wizard. Prompts for your API key and default user ID.
 
 ```bash
-cd node
+mem0 init
+mem0 init --api-key m0-xxx --user-id alice
+mem0 init --email alice@company.com
+```
+
+If an existing configuration is detected, the CLI asks for confirmation before overwriting. Use `--force` to skip the prompt (useful in CI/CD).
+
+```bash
+mem0 init --api-key m0-xxx --user-id alice --force
+```
+
+| Flag | Description |
+|------|-------------|

+| `--email` | Login via email verification code |
+| `--code` | Verification code (use with `--email` for non-interactive login) |
+| `--force` | Overwrite existing config without confirmation |
+
+### `mem0 add`
+

+
+```bash

+| `--before` | Created before date (YYYY-MM-DD) |
+| `-o, --output` | Output format: `text`, `json`, `table` |
+
+### `mem0 get`
+
+Retrieve a specific memory by ID.

+### `mem0 delete`
+
+Delete a single memory, all memories for a scope, or an entire entity.
+
+```bash
+# Delete a single memory

+
+# Delete all memories project-wide
+mem0 delete --all --project --force

+```
+
+| Flag | Description |
+|------|-------------|
+| `--all` | Delete all memories matching scope filters |
+| `--entity` | Delete the entity and all its memories |
+| `--project` | With `--all`: delete all memories project-wide |
+| `--dry-run` | Preview without deleting |
+| `--force` | Skip confirmation prompt |
+
+### `mem0 import`
+
+Bulk import memories from a JSON file.
+
+```bash
+mem0 import data.json --user-id alice
+```
+
+The file should be a JSON array where each item has a `memory` (or `text` or `content`) field and optional `user_id`, `agent_id`, and `metadata` fields.
+
+### `mem0 config`
+
+View or modify the local CLI configuration.
+
+```bash
+mem0 config show              # Display current config (secrets redacted)
+mem0 config get api_key       # Get a specific value
+mem0 config set user_id bob   # Set a value
+```
+
+### `mem0 entity`
+
+List or delete entities (users, agents, apps, runs).
+
+```bash
+mem0 entity list users
+mem0 entity list agents --output json
+mem0 entity delete --user-id alice --force
+```
+
+### `mem0 event`
+
+Inspect background processing events created by async operations (e.g. bulk deletes, large add jobs).
+
+```bash
+# List recent events
+mem0 event list
+
+# Check the status of a specific event
+mem0 event status <event-id>
+```
+
+| Flag | Description |
+|------|-------------|
+| `-o, --output` | Output format: `text`, `json` |
+
+### `mem0 status`
+
+Verify your API connection and display the current project.
+
+```bash
+mem0 status
+```
+
+### `mem0 version`
+
+Print the CLI version.
+
+```bash
+mem0 version
+```
+
+## Agent mode
+
+Pass `--agent` (or its alias `--json`) as a **global flag** on any command to get output designed for AI agent tool loops:
+
+```bash
+mem0 --agent search "user preferences" --user-id alice
+mem0 --agent add "User prefers dark mode" --user-id alice
+mem0 --agent list --user-id alice
+mem0 --agent delete --all --user-id alice --force
+```
+
+Every command returns the same envelope shape:
+
+```json
+{
+  "status": "success",
+  "command": "search",
+  "duration_ms": 134,
+  "scope": { "user_id": "alice" },
+  "count": 2,
+  "data": [
+    { "id": "abc-123", "memory": "User prefers dark mode", "score": 0.97, "created_at": "2026-01-15", "categories": ["preferences"] }
+  ]
+}
+```
+
+What agent mode does differently from `--output json`:
+
+- **Sanitized `data`**: only the fields an agent needs (id, memory, score, etc.) — no internal API noise
+- **No human output**: spinners, colors, and banners are suppressed entirely
+- **Errors as JSON**: errors go to stdout as `{"status": "error", "command": "...", "error": "..."}` with a non-zero exit code
+
+Use `mem0 help --json` to get the full command tree as JSON — useful for agents that need to self-discover available commands.
+
+## Output formats
+
+Control how results are displayed with `--output`:
+
+| Format | Description |
+|--------|-------------|
+| `text` | Human-readable with colors and formatting (default) |
+| `json` | Structured JSON for piping to `jq` (raw API response) |
+| `table` | Tabular format (default for `list`) |
+| `quiet` | Minimal — just IDs or status codes |
+| `agent` | Structured JSON envelope with sanitized fields (set by `--agent`/`--json`) |
+
+## Global flags
+
+These flags are available on all commands:
+
+| Flag | Description |
+|------|-------------|
+| `--json` | Enable agent mode: structured JSON envelope output, no colors or spinners |
+| `--agent` | Alias for `--json` |
+| `--api-key` | Override the configured API key for this request |
+| `--base-url` | Override the configured API base URL for this request |
+| `-o, --output` | Set the output format |
+
+## Environment variables
+
+| Variable | Description |
+|----------|-------------|
+| `MEM0_API_KEY` | API key (overrides config file) |
+| `MEM0_BASE_URL` | API base URL |
+| `MEM0_USER_ID` | Default user ID |
+| `MEM0_AGENT_ID` | Default agent ID |
+| `MEM0_APP_ID` | Default app ID |
+| `MEM0_RUN_ID` | Default run ID |
+| `MEM0_ENABLE_GRAPH` | Enable graph memory (`true` / `false`) |
+
+Environment variables take precedence over values in the config file, which take precedence over defaults.

+
+```bash
+mem0 init
+mem0 init --api-key m0-xxx --user-id alice
+mem0 init --email alice@company.com
+```
+
+If an existing configuration is detected, the CLI asks for confirmation before overwriting. Use `--force` to skip the prompt (useful in CI/CD).

+| `--project` | With `--all`: delete all memories project-wide |
+| `--dry-run` | Preview without deleting |
+| `--force` | Skip confirmation prompt |
+
+### `mem0 import`
+
+Bulk import memories from a JSON file.
+
+```bash
+mem0 import data.json --user-id alice
+```
+
+The file should be a JSON array where each item has a `memory` (or `text` or `content`) field and optional `user_id`, `agent_id`, and `metadata` fields.
+
+### `mem0 config`
+
+View or modify the local CLI configuration.
+
+```bash
+mem0 config show              # Display current config (secrets redacted)
+mem0 config get api_key       # Get a specific value
+mem0 config set user_id bob   # Set a value
+```
+
+### `mem0 entity`
+
+List or delete entities (users, agents, apps, runs).
+
+```bash
+mem0 entity list users
+mem0 entity list agents --output json
+mem0 entity delete --user-id alice --force
+```
+
+### `mem0 event`
+
+Inspect background processing events created by async operations (e.g. bulk deletes, large add jobs).
+
+```bash
+# List recent events
+mem0 event list
+
+# Check the status of a specific event
+mem0 event status <event-id>
+```
+
+| Flag | Description |
+|------|-------------|
+| `-o, --output` | Output format: `text`, `json` |
+
+### `mem0 status`
+
+Verify your API connection and display the current project.
+
+```bash
+mem0 status
+```
+
+### `mem0 version`
+
+Print the CLI version.
+
+```bash
+mem0 version
+```
+
+## Agent mode
+
+Pass `--agent` (or its alias `--json`) as a **global flag** on any command to get output designed for AI agent tool loops:
+
+```bash
+mem0 --agent search "user preferences" --user-id alice
+mem0 --agent add "User prefers dark mode" --user-id alice
+mem0 --agent list --user-id alice
+mem0 --agent delete --all --user-id alice --force
+```
+
+Every command returns the same envelope shape:
+
+```json
+{
+  "status": "success",
+  "command": "search",
+  "duration_ms": 134,
+  "scope": { "user_id": "alice" },
+  "count": 2,
+  "data": [
+    { "id": "abc-123", "memory": "User prefers dark mode", "score": 0.97, "created_at": "2026-01-15", "categories": ["preferences"] }
+  ]
+}
+```
+
+What agent mode does differently from `--output json`:
+
+- **Sanitized `data`**: only the fields an agent needs (id, memory, score, etc.) — no internal API noise
+- **No human output**: spinners, colors, and banners are suppressed entirely
+- **Errors as JSON**: errors go to stdout as `{"status": "error", "command": "...", "error": "..."}` with a non-zero exit code
+
+Use `mem0 help --json` to get the full command tree as JSON — useful for agents that need to self-discover available commands.
+
+## Output formats
+
+Control how results are displayed with `--output`:
+
+| Format | Description |
+|--------|-------------|
+| `text` | Human-readable with colors and formatting (default) |
+| `json` | Structured JSON for piping to `jq` (raw API response) |
+| `table` | Tabular format (default for `list`) |
+| `quiet` | Minimal — just IDs or status codes |
+| `agent` | Structured JSON envelope with sanitized fields (set by `--agent`/`--json`) |
+
+## Global flags
+
+These flags are available on all commands:
+
+| Flag | Description |
+|------|-------------|
+| `--json` | Enable agent mode: structured JSON envelope output, no colors or spinners |
+| `--agent` | Alias for `--json` |
+| `--api-key` | Override the configured API key for this request |
+| `--base-url` | Override the configured API base URL for this request |
+| `-o, --output` | Set the output format |
+
+## Environment variables
+
+| Variable | Description |
+|----------|-------------|
+| `MEM0_API_KEY` | API key (overrides config file) |
+| `MEM0_BASE_URL` | API base URL |
+| `MEM0_USER_ID` | Default user ID |
+| `MEM0_AGENT_ID` | Default agent ID |
+| `MEM0_APP_ID` | Default app ID |
+| `MEM0_RUN_ID` | Default run ID |
+| `MEM0_ENABLE_GRAPH` | Enable graph memory (`true` / `false`) |
+
+Environment variables take precedence over values in the config file, which take precedence over defaults.
+
+## Development
+
+```bash
+cd cli/python
+python -m venv .venv && source .venv/bin/activate
+pip install -e ".[dev]"
+
+# Run during development
+python -m mem0_cli --help
+mem0 add "test memory" --user-id alice
+```
+
+## Releasing
+
+1. Update `version` in `pyproject.toml`
+2. Create a GitHub Release with tag `cli-v<version>` (e.g. `cli-v0.2.1`)
+
+For a pre-release, use a beta version like `0.2.1b1` and check the **pre-release** checkbox.

+**New Memory Algorithm — State-of-the-Art Accuracy at ~3-4x Lower Cost**
+
+Ground-up rewrite of the memory pipeline with 20+ point benchmark improvements:
+
+- **LoCoMo:** 71.4 → **91.6** (+20) — multi-turn conversation recall
+- **LongMemEval:** 67.8 → **93.4** (+26) — long-term memory across sessions
+- **BEAM (1M tokens):** **64.1** — production-scale memory evaluation
+- **Agent memories are first-class** — Previous algorithm: 46% on assistant recall. New: **100%**
+- **Temporal reasoning works** — "Where did I live before SF?" Previous: 51%. New: **93%**
+- **~3-4x fewer tokens** — Under 7K tokens per retrieval vs 25K+ for full-context approaches
+- **ADD-only extraction** — Memories accumulate; nothing is overwritten or deleted
+- **Hybrid retrieval** — Semantic + BM25 keyword + entity boost, scored in parallel
+- **Entity linking** — Entities extracted, embedded, and linked across memories

+**Bug Fixes:**

+- **Telemetry:** Added PostHog `$identify` event on first authenticated run to stitch anonymous history onto the authenticated profile ([#4790](https://github.com/mem0ai/mem0/pull/4790))
+- **Telemetry:** Fixed event loss on short-lived CLI invocations — added `beforeExit` handler to flush queued events before the process exits ([#4790](https://github.com/mem0ai/mem0/pull/4790))
+- **Telemetry:** Added lazy `/v1/ping/` email resolution so users who configure API key outside `mem0 init` show as their email in PostHog, not an md5 hash ([#4790](https://github.com/mem0ai/mem0/pull/4790))
+- **Telemetry:** Unified CLI event prefix from `openclaw.<cmd>` to `openclaw.cli.<cmd>` on the needsSetup branch to match the authenticated branch ([#4790](https://github.com/mem0ai/mem0/pull/4790))
+
+**Improvements:**

+- **OSS pgvector crash** ([#4727](https://github.com/mem0ai/mem0/issues/4727)): Fixed "Client has already been connected" cascade when using pgvector in OSS mode. The warmup call swallowed errors leaving a half-initialized pg client; concurrent recall/capture then all hit `client.connect()` on the same client. Fix: let warmup errors propagate (so `initPromise` resets and retries with a fresh Memory + fresh pg client) and build fresh config objects per attempt instead of mutating shared state.
+
+**Removed:**
+- **`orgId` / `projectId` config parameters**: Removed from config schema, CLI (`config show/get/set`), init display, and providers. The API key is project-scoped, so separate org/project IDs are unnecessary and could cause access errors if mismatched.
+- **`enableGraph` config parameter**: Removed from all config surfaces, providers, backend, and tools. Graph memory is being deprecated — removing the flag avoids unnecessary exposure.
+
+</Update>
+
+<Update label="2026-04-04" description="v1.0.4">
+
+**New Features:**
+- **Interactive init flow**: `openclaw mem0 init` with interactive menu (email verification or direct API key). Non-interactive modes: `--api-key`, `--email`, `--email --code`
+- **`memory_add` tool**: Replaces `memory_store` — name now matches `mem0` CLI and platform API
+- **`memory_delete` tool**: Unified delete — single ID, search-then-delete, bulk, entity cascade. Replaces `memory_forget` and `memory_delete_all`
+- **CLI subcommands**: `openclaw mem0 init`, `openclaw mem0 status`, `openclaw mem0 config show`, `openclaw mem0 config set`
+- **`import` CLI command**: Bulk-import memories from a JSON file with `--user-id` and `--agent-id` overrides
+- **`event list` / `event status` CLI commands**: Monitor background processing events
+- **`fs-safe.ts` module**: Isolated filesystem wrappers in a separate entry point
+- **`backend/` module**: `PlatformBackend` with direct HTTP API access for CLI commands
+- **Plugin manifest**: Added `contracts.tools`, `configSchema`, and `uiHints` to `openclaw.plugin.json`
+- **Test suite**: 329 tests across 10 test files
+
+**Changes:**
+- **Modular architecture**: Extracted tools into `tools/` directory (6 files) and CLI into `cli/commands.ts`
+- **Code splitting**: tsup builds with `splitting: true` and two entry points
+- **Skills updated**: All SKILL.md files reference new tool names (`memory_add`, `memory_delete`)
+- **Auto-recall timeout**: Recall wrapped in 8-second `Promise.race`
+- **Auto-capture fire-and-forget**: `provider.add()` runs in background via `.then()/.catch()`
+- **Auto-capture minimum content gate**: Skips extraction when total user content is fewer than 50 chars
+
+**Removed:**
+- `memory_store` tool — replaced by `memory_add`
+- `memory_forget` tool — replaced by `memory_delete`
+- `memory_delete_all` tool — merged into `memory_delete`
+- `memory_history` tool and `history` CLI command — deprecated
+
+</Update>
+
+<Update label="2026-04-03" description="v1.0.3">
+
+**Bug Fixes:**
+- **Security**: Added `safePath()` containment helper to `readSkillFile` and `readDomainOverlay` in `skill-loader.ts` — prevents directory traversal
+- **Noise filter**: Reverted incorrect `After-Compaction` regex rename back to `Post-Compaction`
+
+**Changes:**
+- **Supply-chain hardening**: Pinned `mem0ai` dependency to exact `2.3.0` (was `^2.3.0`)
+
+**Tests:**
+- 12 new tests covering `safePath`, `readSkillFile`, `readDomainOverlay`, and `loadSkill` with traversal inputs
+
+</Update>
+
+<Update label="2026-04-02" description="v1.0.2">
+
+**Bug Fixes:**
+- **Security**: Removed `resolveEnvVars()` and `resolveEnvVarsDeep()` from `config.ts` — plugin-side env resolution was redundant and triggered static analysis warnings ([#4676](https://github.com/mem0ai/mem0/pull/4676))
+
+</Update>
+
+<Update label="2026-04-02" description="v1.0.1">

+<Update label="2026-04-14" description="v2.0.0">
+
+**Major Release** — Python SDK with V3 memory pipeline, ADD-only extraction, and cleaned-up API surface.
+
+**New Features:**
+- **Single-Pass Extraction:** Replaced 2-LLM-call pipeline with additive extraction using `ADDITIVE_EXTRACTION_PROMPT`. Memories accumulate via `linked_memory_ids` — no more UPDATE/DELETE events ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **Hybrid Search:** Combined semantic + BM25 keyword matching + entity boost with additive scoring. Native `keyword_search()` added to 15 vector store adapters (Qdrant, Elasticsearch, OpenSearch, Azure AI Search, Weaviate, Redis, PGVector, Pinecone, Databricks, MongoDB, Milvus, Baidu, Upstash, Azure MySQL, Vertex AI) ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **Entity Extraction & Linking:** spaCy-based entity extraction with second vector collection (`{collection}_entities`) for cross-memory relationship retrieval. Optional dependency: `pip install mem0ai[nlp]` ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **Batch Operations:** Batch embedding, batch persist, and batch entity linking (8-phase pipeline) for both sync `Memory` and async `AsyncMemory` at full parity ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **Message Persistence:** SQLite-based rolling window (10 messages per session scope) for LLM context ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **Valkey Cluster Mode:** Added `cluster_mode` parameter for Valkey Cluster Mode Enabled (CME) deployments ([#4759](https://github.com/mem0ai/mem0/pull/4759))
+- **V3 API Endpoints:** `MemoryClient.add()` now posts to `/v3/memories/add/`; `MemoryClient.get_all()` posts to `/v3/memories/` and returns a paginated envelope `{"count": int, "next": str | None, "previous": str | None, "results": [...]}` ([#4856](https://github.com/mem0ai/mem0/pull/4856))
+- **Default model:** `gpt-5-mini` is now the default across `OpenAILLM`, `OpenAIStructuredLLM`, `AzureOpenAILLM`, `AzureOpenAIStructuredLLM`, and `LiteLLM` fallback ([#4829](https://github.com/mem0ai/mem0/pull/4829))
+
+**Breaking Changes:**
+- **`add()` returns ADD-only events** — No more `"UPDATE"` or `"DELETE"` events. Memories accumulate; nothing is overwritten ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **`search()` default `threshold` is now `0.1`** — Pass `threshold=0.0` for previous behavior ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **`search()` `score` is now a combined multi-signal score** — The top-level `score` fuses semantic similarity, BM25 keyword match, and entity boost into one value. Absolute numbers shift versus the old raw cosine score; retune any hard thresholds against representative queries. Per-signal scores are not exposed on the response ([#4805](https://github.com/mem0ai/mem0/pull/4805), [#4836](https://github.com/mem0ai/mem0/pull/4836))
+- **`search()` default `rerank` is now `False`** — Pass `rerank=True` for previous behavior ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **`top_k` default changed 100 → 20** in `Memory.get_all()` and `Memory.search()` (sync + async). Pass `top_k=100` explicitly to restore the old behavior ([#4843](https://github.com/mem0ai/mem0/pull/4843))
+- **Entity ID validation:** `user_id` / `agent_id` / `run_id` are trimmed; empty-string and whitespace-only values now raise `ValueError` ([#4843](https://github.com/mem0ai/mem0/pull/4843))
+- **Search params validation:** `threshold` must be a number in `[0, 1]`; `top_k` must be a non-negative integer — invalid inputs raise `ValueError` ([#4843](https://github.com/mem0ai/mem0/pull/4843))
+- **`messages` in `Memory.add()` rejects invalid types:** Passing `None` or non-`(str | dict | list)` values raises `Mem0ValidationError` (`error_code="VALIDATION_003"`) ([#4843](https://github.com/mem0ai/mem0/pull/4843))
+- **`qdrant-client>=1.12.0` required** — Upgrade from `>=1.9.1` ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **`org_id` and `project_id` removed** — Removed from `MemoryClient` constructor and all method signatures ([#4740](https://github.com/mem0ai/mem0/pull/4740))
+- **Graph Memory Removed (OSS):** `mem0/memory/graph_memory.py`, `memgraph_memory.py`, `kuzu_memory.py`, `apache_age_memory.py`, and `mem0/graphs/` (Neo4j / Memgraph / Kuzu / Apache AGE / Neptune drivers) deleted — ~4,000 lines. Graph memory is no longer supported in the OSS SDK; graph drivers (neo4j, memgraph, kuzu, etc.) can be uninstalled. Use the Platform API for graph features. Remove `enable_graph` and `graph_store` from your config ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **`enable_graph` removed from Client SDK** — Graph memory is now a project-level setting on the Platform. Remove `enable_graph` from `MemoryClient.add()` / `search()` / `get_all()` / `update_project()` calls ([#4776](https://github.com/mem0ai/mem0/pull/4776))
+- **`custom_fact_extraction_prompt` renamed to `custom_instructions`** — Update config and memory module references ([#4740](https://github.com/mem0ai/mem0/pull/4740))
+- **Typed option classes** — Added Pydantic v2 typed classes: `AddMemoryOptions`, `SearchMemoryOptions`, `GetAllMemoryOptions`, `DeleteAllMemoryOptions`, `UpdateMemoryOptions`, `ProjectUpdateOptions` ([#4740](https://github.com/mem0ai/mem0/pull/4740))
+
+**Security:**
+- **FAISS:** Prevent arbitrary code execution via pickle deserialization in `FAISS` vector store ([#4833](https://github.com/mem0ai/mem0/pull/4833))
+
+**Bug Fixes:**
+- **V3 migration crashes:** Fixed crashes in the v3 migration path; entity linking on OSS is now functional across Qdrant and Milvus backends ([#4836](https://github.com/mem0ai/mem0/pull/4836))
+- **Qdrant entity store:** Entity store now shares the existing Qdrant client when using embedded mode (`path=...`), eliminating RocksDB lock contention between the main and entity collections ([#4836](https://github.com/mem0ai/mem0/pull/4836))
+- **Reranker:** Fixed incorrect use of SentenceTransformer for cross-encoder reranker models — switched to CrossEncoder API for proper scoring ([#4806](https://github.com/mem0ai/mem0/pull/4806))
+- **S3 Vectors:** Handle `vector=None` in `update()` to prevent boto3 validation error when `event=NONE` ([#4594](https://github.com/mem0ai/mem0/pull/4594))
+- **LLMs:** Made OpenAI `store` parameter opt-in to prevent leaking to non-OpenAI backends like Google Gemini ([#4757](https://github.com/mem0ai/mem0/pull/4757))
+- **LLMs:** Forward `response_format` to Azure OpenAI API to prevent JSON parsing failures ([#4689](https://github.com/mem0ai/mem0/pull/4689))
+- **Core:** Guard `temp_uuid_mapping` lookups against LLM-hallucinated IDs with safe `.get()` and warnings ([#4674](https://github.com/mem0ai/mem0/pull/4674))
+- **Client:** Prevent `MemoryClient.feedback()` telemetry TypeError by merging feedback data into single payload ([#4795](https://github.com/mem0ai/mem0/pull/4795))
+
+**Improvements:**
+- **Telemetry:** Sample OSS hot-path events at 10% via PostHog `before_send` hook to reduce event volume ([#4771](https://github.com/mem0ai/mem0/pull/4771))
+
+See the [OSS v1 to v2 migration guide](https://docs.mem0.ai/migration/oss-v1-to-v2) and [Platform migration guide](https://docs.mem0.ai/migration/platform-v2-to-v3) for upgrade instructions.

+
+**Bug Fixes:**
+- **Telemetry:** SDK version is now injected into telemetry at build time via esbuild's `define`, replacing the two hardcoded version strings in `src/client/telemetry.ts` and `src/oss/src/utils/telemetry.ts`. Previously these were stuck at `2.1.36` and `2.1.34` while the published package was on `3.x`, so every telemetry event was reporting the wrong `client_version`. The placeholder is substituted with a string literal at bundle time — no runtime `require("./package.json")` in the shipped bundle ([#4897](https://github.com/mem0ai/mem0/pull/4897)).

+<Update label="2026-04-14" description="v3.0.0">
+
+**Major Release** — TypeScript SDK with V3 memory pipeline, camelCase parameters, and cleaned-up API surface.
+
+**V3 Memory Pipeline (OSS):**
+- **Single-Pass Extraction:** Additive extraction pipeline aligned with Python SDK — memories accumulate, no UPDATE/DELETE events ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **Entity Extraction & Linking:** New `entity_extraction.ts` module (720+ lines) with cross-memory relationship retrieval ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **Message Persistence:** SQLite-based message history via new `SQLiteManager.ts` with rolling window for LLM context ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **Batch Embeddings:** `embedBatch()` support in OpenAI and Azure embedding providers ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **Scoring & Lemmatization:** New `scoring.ts` and `lemmatization.ts` utilities for hybrid search ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **New Prompts:** `prompts/index.ts` (592+ lines) with additive extraction prompt aligned with Python SDK ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **V3 API Endpoints:** `MemoryClient.add()` now posts to `/v3/memories/add/`; `MemoryClient.getAll()` posts to `/v3/memories/` with paginated envelope `{ count, next, previous, results }` ([#4856](https://github.com/mem0ai/mem0/pull/4856))
+- **Default model:** `gpt-5-mini` is now the default in `OpenAI`, `OpenAIStructured`, and `Azure` LLM providers ([#4829](https://github.com/mem0ai/mem0/pull/4829))
+
+**Breaking Changes:**
+- **Graph Memory Removed (OSS):** `graph_memory.ts` (675 lines), `graphs/tools.ts` (267 lines), `graphs/utils.ts` (116 lines), `graphs/configs.ts` (30 lines) deleted. Graph memory is no longer supported in the OSS SDK — use Platform API for graph features ([#4805](https://github.com/mem0ai/mem0/pull/4805))
+- **camelCase Parameters (Client SDK):** All user-facing parameters converted from snake_case to camelCase. Mapping is transparent at API boundary via `camelToSnakeKeys()` / `snakeToCamelKeys()` ([#4776](https://github.com/mem0ai/mem0/pull/4776))
+  ```typescript
+  // Before
+  client.add(messages, { user_id: "alice", top_k: 5 });
+  // After
+  client.add(messages, { userId: "alice", topK: 5 });
+  ```
+- **Per-Method Option Types:** Replaced monolithic `MemoryOptions` with typed interfaces: `AddMemoryOptions`, `SearchMemoryOptions`, `GetAllMemoryOptions`, `DeleteAllMemoryOptions` ([#4740](https://github.com/mem0ai/mem0/pull/4740))
+- **Removed Deprecated Parameters:** `org_id`, `project_id`, `api_version`, `output_format`, `async_mode`, `enable_graph`, `limit` removed from client method signatures. `ClientOptions` reduced to `{ apiKey, host }` only ([#4740](https://github.com/mem0ai/mem0/pull/4740))
+- **`limit` renamed to `topK` (OSS):** Update all search calls ([#4740](https://github.com/mem0ai/mem0/pull/4740))
+- **`topK` default changed 100 → 20** in `Memory.getAll()` and `Memory.search()`. Pass `topK: 100` explicitly to restore the old behavior ([#4843](https://github.com/mem0ai/mem0/pull/4843))
+- **Entity ID validation:** `userId` / `agentId` / `runId` are trimmed; empty-string and whitespace-only values now throw ([#4843](https://github.com/mem0ai/mem0/pull/4843))
+- **Search params validation:** `threshold` must be in `[0, 1]`; `topK` must be a non-negative integer — invalid inputs throw ([#4843](https://github.com/mem0ai/mem0/pull/4843))
+- **`messages` in `Memory.add()` is required:** Passing `undefined` or `null` now throws ([#4843](https://github.com/mem0ai/mem0/pull/4843))
+- **`customPrompt` renamed to `customInstructions` (OSS):** Update memory and vector store configurations ([#4740](https://github.com/mem0ai/mem0/pull/4740))
+- **`enableGraph` removed (OSS):** Config option removed — graph memory no longer available in OSS ([#4776](https://github.com/mem0ai/mem0/pull/4776))
+
+**New Features:**
+- **LLMs:** Added DeepSeek LLM provider with OpenAI-compatible integration using custom baseURL to `api.deepseek.com` ([#4613](https://github.com/mem0ai/mem0/pull/4613))
+- **Entity store isolation:** `MemoryVectorStore` now uses a dedicated `_entities.db` file, preventing entity/memory store collisions ([#4829](https://github.com/mem0ai/mem0/pull/4829), [#4841](https://github.com/mem0ai/mem0/pull/4841))
+- **Payload backward compatibility:** Legacy camelCase payload keys normalized to snake_case on read ([#4841](https://github.com/mem0ai/mem0/pull/4841))
+
+**Bug Fixes:**
+- **V3 migration:** Fixed crashes in the OSS migration path; entity linking works end-to-end ([#4836](https://github.com/mem0ai/mem0/pull/4836))
+- **PGVector init race:** `PGVector.initialize()` now memoises the in-flight init promise ([#4841](https://github.com/mem0ai/mem0/pull/4841))
+- **Redis module detection:** Handles both node-redis v4+ and legacy `moduleList` response shapes ([#4841](https://github.com/mem0ai/mem0/pull/4841))
+- **Config:** Fixed `ConfigManager.mergeConfig()` to only include `graphStore` when explicitly provided by user, preventing default Neo4j connection attempts ([#4776](https://github.com/mem0ai/mem0/pull/4776))
+- **LLMs:** Config manager now falls back to `userConf.url` for `baseURL` — prevents custom LLM providers (Ollama, LMStudio) from silently connecting to OpenAI ([#4761](https://github.com/mem0ai/mem0/pull/4761))
+
+**Improvements:**
+- **Telemetry:** Sample OSS hot-path events at 10% to reduce PostHog event volume ([#4771](https://github.com/mem0ai/mem0/pull/4771))
+
+See the [TypeScript SDK migration guide](https://docs.mem0.ai/migration/ts-v2-to-v3) for upgrade instructions.

+- **Agent output sanitization:** Raw API responses projected to only relevant fields per command (e.g., `add` → `{id, memory, event}`, `search` → `{id, memory, score, created_at, categories}`) ([#4649](https://github.com/mem0ai/mem0/pull/4649))

@@ -50,4 +50,25 @@ Here are the parameters available for configuring Valkey:
 | `hnsw_m` | Number of bi-directional links for HNSW | `16` |
 | `hnsw_ef_construction` | Size of dynamic candidate list for HNSW | `200` |
 | `hnsw_ef_runtime` | Size of dynamic candidate list for search | `10` |
+| `cluster_mode` | Enable cluster mode for Valkey cluster (CME) deployments | `false` |
 | `distance_metric` | Distance metric for vector similarity | `cosine` |
+
+## Cluster Mode
+
+To use Valkey with cluster mode enabled (CME), set `cluster_mode` to `true`:
+
+```python
+config = {
+    "vector_store": {
+        "provider": "valkey",
+        "config": {
+            "collection_name": "memories",

+            "cluster_mode": True
+        }
+    }
+}
+```
+
+When cluster mode is enabled, the connector uses `ValkeyCluster` instead of the standalone client, which handles `MOVED`/`ASK` redirections automatically. Search queries are coordinated across all shards by the valkey-search module's built-in coordinator. See the [valkey-search documentation](https://github.com/valkey-io/valkey-search) for details on cluster mode behavior.

-title: Choose Vector vs Graph Memory
-description: "Blend vector search with graph relationships to answer multi-hop questions."
----
-
-
-Most AI agents use vector stores for RAG operations - they work great for semantic search and retrieving relevant context. But there's a gap when queries require understanding connections between entities.
-
-Mem0 brings graph memory into the picture to fill this gap. In this cookbook, we'll create a company knowledge base with Mem0, using both vector and graph stores. You'll learn when each one helps along the way.
-
----
-
-## Vector and Graph Stores
-
-When you add a memory to Mem0, it goes into a **vector store** by default. Vector stores are excellent at semantic search - finding memories that match the meaning of your query.
-
-**Graph stores** work differently. They extract **entities** (people, projects, teams) and **relationships between them** (works_with, reports_to, member_of). This lets you answer questions that need connecting information across multiple memories.
-
-We will go through examples in this cookbook while building a company's knowledge base along the way.
-
----
-
-## Starting Simple
-
-Since we're building a company knowledge base, let's add some employee information:
-
-```python
-from mem0 import MemoryClient
-
-client = MemoryClient(api_key="your-api-key")
-# Add employee info
-client.add("Emma is a software engineer in Seattle", user_id="company_kb")
-client.add("David is a product manager in Austin", user_id="company_kb")
-
-```
-
-Now let's search for Emma's role:
-
-```python
-results = client.search("What does Emma do?", filters={"user_id": "company_kb"})
-print(results['results'][0]['memory'])
-
-```
-
-**Output:**
-
-```
-Emma is a software engineer in Seattle
-
-```
-
-<Info>
-**Expected output:** Vector search returned Emma's role instantly. When queries ask for facts directly stored in one memory, vector semantic search is perfect—fast and accurate.
-</Info>
-
-This works perfectly. Vector search found the memory that semantically matches "What does Emma do?" and returned Emma's role.
-
----
-
-## Adding Team Structure
-
-Let's add some information about how the team works together:
-
-```python
-client.add("Emma works with David on the mobile app redesign", user_id="company_kb")
-client.add("David reports to Rachel, who manages the design team", user_id="company_kb")
-
-```
-
-Now we have two pieces of information stored:
-
-1. Emma works with David
-2. David reports to Rachel
-
-Let's try asking something that needs both pieces:
-
-```python
-results = client.search(
-    "Who is Emma's teammate's manager?",
-    filters={"user_id": "company_kb"}
-)
-
-for r in results['results']:
-    print(r['memory'])
-
-```
-
-**Output:**
-
-```
-Emma works with David on the mobile app redesign
-David reports to Rachel, who manages the design team
-
-```
-
-Vector search returned both memories, but it didn't connect them. You'd need to manually figure out:
-
-- Emma's teammate is David (from memory 1)
-- David's manager is Rachel (from memory 2)
-- So the answer is Rachel
-
-<Warning>
-Vector search can't traverse relationships. It returns relevant memories, but you must connect the dots manually. For "Who is Emma's teammate's manager?", vector search gives you the pieces—not the answer. This breaks down as queries get more complex (3+ hops).
-</Warning>
-
----
-
-## Enter Graph Memory
-
-Let's add the same information with graph memory enabled:
-
-```python
-client.add(
-    "Emma works with David on the mobile app redesign",
-    user_id="company_kb",
-    enable_graph=True
-)
-
-client.add(
-    "David reports to Rachel, who manages the design team",
-    user_id="company_kb",
-    enable_graph=True
-)
-
-```
-
-When you set `enable_graph=True`, Mem0 extracts entities and relationships:
-
-- `emma --[works_with]--> david`
-- `david --[reports_to]--> rachel`
-- `rachel --[manages]--> design_team`
-
-Now the same query works differently:
-
-```python
-results = client.search(
-    "Who is Emma's teammate's manager?",
-    filters={"user_id": "company_kb"},
-    enable_graph=True
-)
-
-print(results['results'][0]['memory'])
-print("\\nRelationships found:")
-for rel in results.get('relations', []):
-    print(f"  {rel['source']}, {rel['target']} ({rel['relationship']})")
-
-```
-
-**Output:**
-
-```
-David reports to Rachel, who manages the design team
-
-Relationships found:
-  emma, david (works_with)
-  david, rachel (reports_to)
-
-```
-
-<Info>
-**Expected behavior:** Graph memory returns the direct answer—"David reports to Rachel"—plus the relationship chain that got there. No manual connecting needed. The graph traversed: Emma → works_with → David → reports_to → Rachel.
-</Info>
-
-Graph memory traversed the relationships automatically: Emma works with David, David reports to Rachel, so Rachel is the answer.
-
----
-
-## How It Connects
-
-Here's what the graph looks like behind the scenes:
-
-```mermaid
-graph LR
-    Emma[Emma] -->|works_with| David[David]
-    David -->|reports_to| Rachel[Rachel]
-    Rachel -->|manages| DesignTeam[Design Team]
-    David -->|works_on| MobileApp[Mobile App]
-    Emma -->|works_on| MobileApp
-
-```
-
-Graph memory lets you discover relations and memories which are tricky to do with direct vector stores.
-
-Vector search would need the exact words in your query to match. Graph memory follows the connections.
-
----
-
-## When to Use Each
-
-Use **vector store** (default) when:
-
-- Searching documents by semantic similarity
-- Looking up facts that don't need relationships
-- Building FAQs or knowledge bases where each item stands alone
-
-Use **graph memory** when:
-
-- Tracking organizational hierarchies (who reports to whom)
-- Understanding project teams (who collaborates with whom)
-- Building CRMs (which contacts connect to which companies)
-- Product recommendations (what items are bought together)
-
-For our company knowledge base, we'll use both:
-
-- Vector for individual facts: "Emma specializes in React"
-- Graph for relationships: "Emma works with David"
-
----
-
-## Putting It Together
-
-Let's build a small company knowledge base with both approaches:
-
-```python
-# Facts about individuals - vector store is fine
-client.add("Emma specializes in React and TypeScript", user_id="company_kb")
-client.add("David has 5 years of product management experience", user_id="company_kb")
-
-# Relationships - use graph memory
-client.add(
-    "Emma and David work together on the mobile app",
-    user_id="company_kb",
-    enable_graph=True
-)
-
-client.add(
-    "David reports to Rachel",
-    user_id="company_kb",
-    enable_graph=True
-)
-
-client.add(
-    "Rachel runs weekly team syncs every Tuesday",
-    user_id="company_kb",
-    enable_graph=True
-)
-
-```
-
-Now we can ask different types of questions:
-
-```python
-# Direct fact - vector search
-results = client.search("What are Emma's skills?", filters={"user_id": "company_kb"})
-print(results['results'][0]['memory'])
-
-```
-
-**Output:**
-
-```
-Emma specializes in React and TypeScript
-
-```
-
-```python
-# Multi-hop relationship - graph search
-results = client.search(
-    "What meetings does Emma's project manager's boss run?",
-    filters={"user_id": "company_kb"},
-    enable_graph=True
-)
-print(results['results'][0]['memory'])
-
-```
-
-**Output:**
-
-```
-Rachel runs weekly team syncs every Tuesday
-
-```
-
-Graph memory connected: Emma works with David, David reports to Rachel, Rachel runs team syncs.
-
-<Tip>
-Enable graph memory when your queries need multi-hop traversal: org charts (who reports to whom), project teams (who collaborates), CRMs (which contacts connect to companies). For single-fact lookups, stick with vector search—it's faster and cheaper.
-</Tip>
-
----
-
-## The Tradeoff
-
-Graph memory adds processing time and cost. When you call `client.add()` with `enable_graph=True`, Mem0 makes extra LLM calls to extract entities and relationships.
-
-<Note>
-**Cost consideration:** Graph memory extraction adds ~2-3 extra LLM calls per `add()` operation to identify entities and relationships. Use it selectively—enable graph for organizational structure and long-term relationships, skip it for temporary notes and simple facts.
-</Note>
-
-Use graph memory when the relationship traversal adds real value. For most use cases, vector search is sufficient and faster.
-
-```python
-# Long-term organizational structure - worth using graph
-client.add(
-    "Emma mentors two junior engineers on the frontend team",
-    user_id="company_kb",
-    enable_graph=True
-)
-
-# Temporary notes - skip graph, not worth the cost
-client.add(
-    "Emma is out sick today",
-    user_id="company_kb",
-    run_id="daily_notes"
-)
-
-```
-
----
-
-## Enabling Graph Memory
-
-You can enable graph memory in two ways:
-
-**Per-call** (recommended to start):
-
-```python
-client.add("Emma works with David", user_id="company_kb", enable_graph=True)
-client.search("team structure", filters={"user_id": "company_kb"}, enable_graph=True)
-
-```
-
-**Project-wide** (if most of your data has relationships):
-
-```python
-client.project.update(enable_graph=True)
-
-# Now every add uses graph automatically
-client.add("Emma mentors Jordan", user_id="company_kb")
-
-```
-
----
-
-## What You Built
-
-A hybrid company knowledge base that combines both architectures:
-
-- **Vector search** - Fast semantic lookups for individual facts (Emma's skills, David's experience)
-- **Graph memory** - Multi-hop relationship traversal (Emma's teammate's manager, project hierarchies)
-- **Selective enablement** - Graph only for long-term organizational structure, vector for everything else
-- **Cost optimization** - Skip graph extraction for temporary notes and simple facts
-
-This pattern scales from 10-person startups to enterprise org charts with thousands of employees.
-
----
-
-## Summary
-
-Vector stores handle most memory operations efficiently—semantic search works great for finding relevant information. Add graph memory when your queries need to understand how entities connect across multiple hops.
-
-The key is knowing which tool fits your query pattern: direct questions work with vectors, multi-hop relationship queries need graphs.
