+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, and documentation.
+
+### 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` |
+| `integrations/` | **Agent & editor integrations**, one directory per integration (see "Adding a New Integration") |
+| `integrations/mem0-plugin/` | AI editor plugins (Claude Code, Cursor, Codex) — MCP server connection, lifecycle hooks, skills. Contains nested `.opencode-plugin/` (`@mem0/opencode-plugin`) |
+| `integrations/openclaw/` | `@mem0/openclaw-mem0` — OpenClaw plugin for Claude Code / AI editors |
+| `integrations/pi-agent-plugin/` | `@mem0/pi-agent-plugin` — Pi Agent plugin |
+| `integrations/vercel-ai-sdk/` | `@mem0/vercel-ai-provider` — Vercel AI SDK memory provider |
+| `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) |
+| `skills/` | Claude Code skill definitions. Reference skills (SDK knowledge, always-on): `mem0/`, `mem0-cli/`, `mem0-vercel-ai-sdk/`. Pipeline skills (run on demand): `mem0-integrate/`, `mem0-test-integration/`, `mem0-oss-to-platform/` |
+| `docs/` | Documentation site (Mintlify) |
+| `tests/` | Python SDK tests (pytest) |
+| `evaluation/` | Submodule → [`mem0ai/memory-benchmarks`](https://github.com/mem0ai/memory-benchmarks) — benchmarking (LOCOMO, LongMemEval, BEAM) lives in that repo |
+| `examples/` | Sample projects & runnable demos — apps, Chrome extension, multi-agent patterns, and Jupyter notebooks (`notebooks/`) |
+| `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 integrations/vercel-ai-sdk && pnpm install  # Vercel AI provider
+cd integrations/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
+```

+
+### Evaluation / Benchmarking
+
+Benchmarking lives in the external [`mem0ai/memory-benchmarks`](https://github.com/mem0ai/memory-benchmarks) repo (LOCOMO + LongMemEval + BEAM). The in-repo `evaluation/` path is a **git submodule** pinned to that repo's `main` — populate it with `git submodule update --init evaluation` (or clone mem0 with `--recurse-submodules`), or clone the benchmarks repo standalone:
+
+```bash
+git clone https://github.com/mem0ai/memory-benchmarks.git
+cd memory-benchmarks
+pip install -r requirements.txt
+
+# Run a benchmark (Mem0 Cloud; use docker compose for OSS)
+python -m benchmarks.locomo.run --project-name my-test --backend cloud --mem0-api-key $MEM0_API_KEY
+python -m benchmarks.longmemeval.run --project-name my-test --backend cloud --mem0-api-key $MEM0_API_KEY --all-questions
+python -m benchmarks.beam.run --project-name my-test --backend cloud --mem0-api-key $MEM0_API_KEY --chat-sizes 100K --conversations 0-9
+```
+
+## 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 `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 |
+| `integrations/vercel-ai-sdk/` | ESLint | Prettier | jest + vitest |
+| `integrations/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 `integrations/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
+
+- `integrations/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, split into two categories:
+  - **Reference skills** (always-on SDK knowledge): `mem0` (Python + TS SDKs, framework integrations), `mem0-cli` (terminal workflows), `mem0-vercel-ai-sdk` (Vercel AI provider).
+  - **Pipeline skills** (run on demand): `mem0-integrate` wires Mem0 into an existing repo via a TDD pipeline; `mem0-test-integration` verifies what the integrator produced on the same branch (the two are loosely coupled via `.mem0-integration/` artifacts); `mem0-oss-to-platform` migrates an existing project from Mem0 OSS to the hosted Platform SDK (plan, then execute on approval).
+
+### 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
+
+### Adding a New Integration
+
+Agent/editor integrations live under `integrations/`. Each is a self-contained directory (its own `package.json`/lockfile, build, and tests). To add one:
+
+1. Create `integrations/<name>/` and build the integration there.
+2. If it publishes to a registry, set `repository.directory: "integrations/<name>"` in its `package.json` so npm provenance links to the correct subdirectory.
+3. Add CI/CD under `.github/workflows/` (`<name>-checks.yml`, `<name>-cd.yml`). Use `integrations/<name>` in `paths:` triggers, `working-directory`, and `cache-dependency-path`. Register the release tag prefix in the `case` block in `release.yml` (keep the bare `v*` arm last). Keep workflow **filenames** stable — npm OIDC trusted publishing is pinned to repo + workflow filename.
+4. If it is a Claude Code / editor marketplace plugin, register its path in the five `marketplace.json` files (root + `.claude-plugin/`, `.cursor-plugin/`, `.codex-plugin/`, `.agents/plugins/`).
+5. Document it under `docs/integrations/` and add the page to `docs/docs.json` and `docs/llms.txt`.
+6. Add rows to the "Key Directories" table and the CI/CD tables in this file.
+
+## CI/CD
+
+### CI Workflows (automated testing)
+
+PR testing is orchestrated by a single entry point: **`ci-gate.yml` (CI Gate)** runs on every PR, detects which packages changed, and invokes only the relevant package workflows below as reusable workflows (`workflow_call`). Its final **`CI Gate`** job aggregates the results (skipped pipelines pass; failed or cancelled ones fail) and is the **only status check that needs to be required** in branch protection. Package workflows keep their own push-to-main and manual triggers; their `pull_request` triggers moved into the gate's path filters.
+
+| Workflow | File | Standalone Triggers | Tests |
+|----------|------|---------------------|-------|
+| CI Gate | `ci-gate.yml` | All PRs | Routes to and aggregates the workflows below |
+| Python SDK | `ci.yml` | Push to main | Ruff lint + pytest on Python 3.10, 3.11, 3.12 |
+| TypeScript SDK | `ts-sdk-ci.yml` | Push to main (on `mem0-ts/`) | Prettier + build + jest on Node 20, 22 |
+| Python CLI | `cli-python-ci.yml` | Push to main (on `cli/python/`), manual | Ruff lint + pytest + hatch build on Python 3.10, 3.11, 3.12 |
+| Node CLI | `cli-node-ci.yml` | Push to main (on `cli/node/`), manual | Biome lint + tsc + vitest + tsup build on Node 20, 22 |
+| OpenClaw | `openclaw-checks.yml` | Push to main (on `integrations/openclaw/`), manual | tsc + vitest (with Codecov) + tsup build on Node 20, 22 |
+| OpenCode Plugin | `opencode-plugin-checks.yml` | Push to main (on `integrations/mem0-plugin/.opencode-plugin/`), manual | Bun: tsc type-check + build + dist artifact check |
+| Pi Agent Plugin | `pi-agent-plugin-checks.yml` | Push to main (on `integrations/pi-agent-plugin/`), manual | tsc + vitest + tsup build (dist artifact check) on Node 20, 22 |
+| docs llms.txt | `docs-llms-txt-check.yml` | Manual | `docs/llms.txt` coverage check |
+
+When adding a new package CI workflow: give it `workflow_call` (plus `push`/`workflow_dispatch` as needed, but no `pull_request` trigger), then register it in `ci-gate.yml` — a path filter under the `changes` job, a call job, and an entry in the gate job's `needs` list.
+
+### CD Workflows (automated publishing)
+
+Publishing is routed through a single entry point: **`release.yml` (Release Router)** is the only workflow that listens to `release: published` events. It matches the release tag prefix and dispatches the corresponding package workflow via `workflow_dispatch`, so each release produces exactly one routed run (no skipped runs from the other pipelines).
+
+| Workflow | File | Tag Prefix | Target |
+|----------|------|------------|--------|
+| Release Router | `release.yml` | (all releases) | dispatches the matching workflow below |
+| 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`) |
+| OpenCode Plugin | `opencode-plugin-cd.yml` | `opencode-v*` | npm (`@mem0/opencode-plugin`) |
+| Pi Agent Plugin | `pi-agent-plugin-cd.yml` | `pi-agent-v*` | npm (`@mem0/pi-agent-plugin`) |
+
+- Package CD workflows are `workflow_dispatch`-only (inputs: `tag`, `prerelease`); they check out and build the given tag. Registry trusted-publisher settings stay pinned to each package's own workflow filename.
+- 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.
+- To re-publish a release (e.g. after a registry settings fix), do **not** delete/recreate the GitHub release — manually dispatch the package workflow instead: `gh workflow run <package>-cd.yml --ref refs/tags/<tag> -f tag=<tag>`.
+- When adding a new package: add its CD workflow (`workflow_dispatch` with `tag`/`prerelease` inputs), then register its tag prefix in the `case` block in `release.yml`. Keep the bare `v*` arm last.
+
+### 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.
+- 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/`.

+## Repository Layout
+
+The two most common contribution targets are the SDKs:
+
+| Package               | Path       | Language     | Package manager |
+| --------------------- | ---------- | ------------ | --------------- |
+| Python SDK (`mem0ai`) | `mem0/`    | Python 3.9+  | `hatch`         |
+| TypeScript SDK (`mem0ai`) | `mem0-ts/` | TypeScript | `pnpm`        |
+
+Other packages include the CLIs (`cli/python/`, `cli/node/`), integrations
+(`integrations/`), the self-hosted `server/`, `openmemory/`, and the docs site
+(`docs/`). See [AGENTS.md](./AGENTS.md) for a full map of the repository.
+
+## Development Workflow
+
+1. **Fork** the repository and **clone** your fork.
+2. Create a **feature branch** from `main` (e.g. `feature/my-new-feature` or
+   `fix/issue-1234`).
+3. Make your changes — add **tests**, **documentation**, and **examples** as
+   appropriate.
+4. Run **linting and tests** for every package you touched (see below).
+5. Commit using [Conventional Commits](https://www.conventionalcommits.org/)
+   (e.g. `feat:`, `fix:`, `docs:`, `refactor:`, `test:`).
+6. Push and open a **pull request** against `main`, linking the issue with
+   `Closes #<number>` and filling out the
+   [PR template](./.github/PULL_REQUEST_TEMPLATE.md).
+
+### Contributing to the Python SDK (`mem0/`)
+
+We use [`hatch`](https://hatch.pypa.io/latest/install/) to manage environments.
+**Do not use `pip` or `conda` for dependency management.**
 
 ```bash
-poetry install --all-extras
-or
-poetry install --with dev
+# Activate a dev environment (3.9 / 3.10 / 3.11 / 3.12)
+hatch shell dev_py_3_11
 
-#activate
-
-poetry shell
-```
-
-### 📌 Pre-commit
-
-To ensure our standards, make sure to install pre-commit before starting to contribute.
-
-```bash
+# Install pre-commit hooks (runs ruff + isort on commit)
 pre-commit install
-```
 
-### 🧹 Linting
-
-We use `ruff` to lint our code. You can run the linter by running the following command:
-
-```bash
+# Lint, format, and sort imports
 make lint
-```
-
-Make sure that the linter does not report any errors or warnings before submitting a pull request.
-
-### Code Formatting with `black`
-
-We use `black` to reformat the code by running the following command:
-
-```bash
 make format
+make sort
+
+# Run the test suite (run `make install_all` first if deps are missing)
+make test
 ```
 
-### 🧪 Testing
+- **Linter / formatter:** Ruff (line length **120**)
+- **Import sorting:** isort (`profile = "black"`)
+- **Tests:** pytest (in `tests/`)
 
-We use `pytest` to test our code. You can run the tests by running the following command:
+See the full [Development guide](https://docs.mem0.ai/contributing/development) for
+environment details.
+
+### Contributing to the TypeScript SDK (`mem0-ts/`)
+
+We use [`pnpm`](https://pnpm.io/) (v10+) for all TypeScript packages. **Do not use
+`npm` or `yarn`.**
 
 ```bash
-poetry run pytest
+cd mem0-ts
+pnpm install
+
+pnpm run build        # tsup (CJS + ESM)
+pnpm run test         # jest (all tests)
+pnpm run test:unit    # unit tests with coverage
 ```
 
-Make sure that all tests pass before submitting a pull request.
+- **Build:** tsup
+- **Formatter:** Prettier
+- **Tests:** jest
+- Always run type checking after changes: `pnpm run typecheck` (or `tsc --noEmit`).
+- Use ES module `import` syntax — never `require()`.
 
-## 🚀 Release Process
+## Good Contribution Practices
 
-At the moment, the release process is manual. We try to make frequent releases. Usually, we release a new version when we have a new feature or bugfix. A developer with admin rights to the repository will create a new release on GitHub, and then publish the new version to PyPI.
+- **Keep PRs small and focused.** One logical change per PR is easier to review and
+  merge.
+- **Follow existing patterns.** Match the style, structure, and conventions of the
+  code around you. Don't introduce new frameworks or abstractions without
+  discussion.
+- **Write tests** that would fail without your change — regression tests for bugs,
+  coverage for new features.
+- **Update documentation** in `docs/` for any user-facing change. New `.mdx` pages
+  must be added to `docs/llms.txt` (run
+  `python scripts/check-llms-txt-coverage.py --write` to scaffold entries).
+- **Add examples** when introducing new user-facing behavior.
+- **Run linters and tests locally** before pushing — CI re-runs them on every PR
+  via the CI Gate.
+- **Never commit secrets** — no `.env` files, API keys, or credentials.
+- **Don't add core dependencies lightly.** New Python dependencies belong in an
+  optional group in `pyproject.toml`, not the core `dependencies` list.
+- **Be responsive** to review feedback and keep your branch up to date with `main`.
+
+## Pull Request Checklist
+
+Before requesting review, make sure:
+
+- [ ] An issue exists and is linked with `Closes #<number>`
+- [ ] You have signed the CLA
+- [ ] Your code follows the project's style guidelines (lint passes)
+- [ ] You performed a self-review of your changes
+- [ ] Tests are added/updated and pass locally
+- [ ] Documentation is updated if needed
+
+## Reporting Security Issues
+
+**Do not report security vulnerabilities through public issues or pull requests.**
+Please follow our [Security Policy](./SECURITY.md) to report them privately.
+
+## Releasing
+
+All packages are published automatically via GitHub Actions when a GitHub Release
+is created with the correct tag prefix.
+
+### Tag Prefixes
+
+| Package | Registry | Tag Prefix | Example |
+|---------|----------|------------|---------|
+| `mem0ai` (Python SDK) | PyPI | `v*` | `v0.1.31` |
+| `mem0-cli` (Python CLI) | PyPI | `cli-v*` | `cli-v0.2.1` |
+| `mem0ai` (TypeScript SDK) | npm | `ts-v*` | `ts-v2.4.6` |
+| `@mem0/cli` (Node CLI) | npm | `cli-node-v*` | `cli-node-v0.1.2` |
+| `@mem0/vercel-ai-provider` | npm | `vercel-ai-v*` | `vercel-ai-v2.0.6` |
+| `@mem0/openclaw-mem0` | npm | `openclaw-v*` | `openclaw-v1.0.1` |
+
+### How to Release
+
+1. Bump the version in `pyproject.toml` (Python) or `package.json` (Node)
+2. Create a [GitHub Release](https://github.com/mem0ai/mem0/releases/new) with the matching tag prefix
+3. The correct workflow will trigger automatically — verify in the [Actions tab](https://github.com/mem0ai/mem0/actions)
+
+### Publishing Details
+
+- **PyPI packages** use OIDC trusted publishing via `pypa/gh-action-pypi-publish`
+- **npm packages** use OIDC trusted publishing via npm CLI (>= 11.5.1) — no tokens or secrets required
+- All workflows require `permissions: id-token: write` for OIDC authentication
+- First publish of a new npm package must be done manually; OIDC works for subsequent versions
+
+We look forward to your pull requests and can't wait to see your contributions!

-## What is Embedchain?
+## New Memory Algorithm (April 2026)
 
-Embedchain is an Open Source RAG Framework that makes it easy to create and deploy AI apps. At its core, Embedchain follows the design principle of being *"Conventional but Configurable"* to serve both software engineers and machine learning engineers.
+| Benchmark | Old | New  | Tokens  | Latency p50  |
+| --- | --- | --- | --- | --- |
+| **LoCoMo** | 71.4 | **91.6** | 7.0K  | 0.88s  |
+| **LongMemEval** | 67.8 | **94.8** | 6.8K  | 1.09s  |
+| **BEAM (1M)** | — | **64.1** | 6.7K  | 1.00s  |
+| **BEAM (10M)** | — | **48.6** | 6.9K  | 1.05s  |
 
-Embedchain streamlines the creation of Retrieval-Augmented Generation (RAG) applications, offering a seamless process for managing various types of unstructured data. It efficiently segments data into manageable chunks, generates relevant embeddings, and stores them in a vector database for optimized retrieval. With a suite of diverse APIs, it enables users to extract contextual information, find precise answers, or engage in interactive chat conversations, all tailored to their own data.
+All benchmarks run on the same production-representative model stack. Single-pass retrieval (one call, no agentic loops).
 
-## 🔧 Quick install
+**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.
+- **Temporal Reasoning** -- time-aware retrieval that ranks the right dated instance for queries about current state, past events, and upcoming plans.
 
-### Python API
+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
+- **94.8 on LongMemEval** -- +27 points, with +53.6 on assistant memory recall
+- **64.1 on BEAM (1M)** -- production-scale memory evaluation at 1M tokens

+
+## 🚀 Quickstart Guide <a name="quickstart"></a>
+
+### Sign up as an agent
+
+AI agents can mint a working Mem0 API key in under five seconds — no email, no dashboard, no OTP. Four commands end-to-end:
 
 ```bash
-pip install embedchain
+# 1. Install
+npm install -g @mem0/cli      # or: pip install mem0-cli
+
+# 2. Sign up as an agent (replace `claude-code` with your name)
+mem0 init --agent --agent-caller claude-code
+
+# 3. Add a memory
+mem0 add "I am using mem0"
+
+# 4. Search
+mem0 search "am I using mem0"
 ```
 
-## ✨ Live demo
+The human owner can claim the account later with `mem0 init --email <their-email>` — same key, memories preserved. Full guide: [Sign up as an agent](https://docs.mem0.ai/platform/agent-signup).

+### Library (pip / npm)
 
-For example, you can create an Elon Musk bot using the following code:
+```bash
+pip install mem0ai
+```
+
+For enhanced hybrid search with BM25 keyword matching and entity extraction, install with NLP support:
+
+```bash
+pip install mem0ai[nlp]
+python -m spacy download en_core_web_sm
+```
+
+Install sdk via npm:
+
+```bash
+npm install mem0ai
+```
+
+### Self-Hosted Server
+
+> **Note:** Self-hosted auth is on by default. Upgrading from a pre-auth build? Set `ADMIN_API_KEY`, register an admin through the wizard, or `AUTH_DISABLED=true` for local dev only. See [upgrade notes](https://docs.mem0.ai/open-source/setup#upgrade-notes).
+
+```bash
+# Recommended: one command — start the stack, create an admin, issue the first API key.
+cd server && make bootstrap
+
+# Manual: start the stack and finish setup via the browser wizard.
+cd server && docker compose up -d    # http://localhost:3000
+```
+
+See the [self-hosted docs](https://docs.mem0.ai/open-source/overview) for configuration.
+
+### Cloud Platform
+
+1. Sign up on [Mem0 Platform](https://app.mem0.ai?utm_source=oss&utm_medium=readme)
+2. Embed the memory layer via SDK or API keys
+3. Using hosted Qdrant vectors? See the [Platform migration guide](https://docs.mem0.ai/migration/oss-to-platform) to import them into Mem0 Platform.
+
+### CLI
+
+Manage memories from your terminal:
+
+```bash
+npm install -g @mem0/cli   # or: pip install mem0-cli
+
+mem0 init
+mem0 add "Prefers dark mode and vim keybindings" --user-id alice
+mem0 search "What does Alice prefer?" --user-id alice
+```
+
+See the [CLI documentation](https://docs.mem0.ai/platform/cli) for the full command reference.
+
+### Agent Skills
+
+Teach your AI coding assistant (Claude Code, Codex, Cursor, Windsurf, OpenCode, OpenClaw, and any tool that supports the skills standard) how to build with Mem0. Two categories:
+
+**Reference skills — always on** (SDK knowledge loaded into the assistant's context):
+
+```bash
+npx skills add https://github.com/mem0ai/mem0 --skill mem0
+npx skills add https://github.com/mem0ai/mem0 --skill mem0-cli
+npx skills add https://github.com/mem0ai/mem0 --skill mem0-vercel-ai-sdk
+```
+
+**Pipeline skills — run on demand** (execute an end-to-end workflow in an existing repo):
+
+```bash
+npx skills add https://github.com/mem0ai/mem0 --skill mem0-integrate
+npx skills add https://github.com/mem0ai/mem0 --skill mem0-test-integration
+npx skills add https://github.com/mem0ai/mem0 --skill mem0-oss-to-platform
+```
+
+Use `/mem0-integrate` to wire Mem0 into an existing repo via a test-first pipeline, then `/mem0-test-integration` to verify. Use `/mem0-oss-to-platform` to migrate an existing project from Mem0 OSS to the hosted Platform SDK. See the [skills catalog](./skills/) or [Vibecoding with Mem0](https://docs.mem0.ai/vibecoding) for the full picture.
+
+### Basic Usage
+
+Mem0 requires an LLM to function, with `gpt-5-mini` from OpenAI as the default. However, it supports a variety of LLMs; for details, refer to our [Supported LLMs documentation](https://docs.mem0.ai/components/llms/overview).
+
+Mem0 uses `text-embedding-3-small` from OpenAI as the default embedding model. For best results with hybrid search (semantic + keyword + entity boosting), we recommend using at least [Qwen 600M](https://huggingface.co/Alibaba-NLP/gte-Qwen2-1.5B-instruct) or a comparable embedding model. See [Supported Embeddings](https://docs.mem0.ai/components/embedders/overview) for configuration details.
+
+First step is to instantiate the memory:
 
 ```python
-import os
-from embedchain import App
+from openai import OpenAI
+from mem0 import Memory
 
-# Create a bot instance
-os.environ["OPENAI_API_KEY"] = "YOUR API KEY"
-elon_bot = App()
+openai_client = OpenAI()
+memory = Memory()
 
-# Embed online resources
-elon_bot.add("https://en.wikipedia.org/wiki/Elon_Musk")
-elon_bot.add("https://www.forbes.com/profile/elon-musk")
+def chat_with_memories(message: str, user_id: str = "default_user") -> str:
+    # Retrieve relevant memories
+    relevant_memories = memory.search(query=message, filters={"user_id": user_id}, top_k=3)
+    memories_str = "\n".join(f"- {entry['memory']}" for entry in relevant_memories["results"])
 
-# Query the bot
-elon_bot.query("How many companies does Elon Musk run and name those?")
-# Answer: Elon Musk currently runs several companies. As of my knowledge, he is the CEO and lead designer of SpaceX, the CEO and product architect of Tesla, Inc., the CEO and founder of Neuralink, and the CEO and founder of The Boring Company. However, please note that this information may change over time, so it's always good to verify the latest updates.
+    # Generate Assistant response
+    system_prompt = f"You are a helpful AI. Answer the question based on query and memories.\nUser Memories:\n{memories_str}"
+    messages = [{"role": "system", "content": system_prompt}, {"role": "user", "content": message}]
+    response = openai_client.chat.completions.create(model="gpt-5-mini", messages=messages)
+    assistant_response = response.choices[0].message.content
+
+    # Create new memories from the conversation
+    messages.append({"role": "assistant", "content": assistant_response})
+    memory.add(messages, user_id=user_id)
+
+    return assistant_response
+
+def main():
+    print("Chat with AI (type 'exit' to quit)")
+    while True:
+        user_input = input("You: ").strip()
+        if user_input.lower() == 'exit':
+            print("Goodbye!")
+            break
+        print(f"AI: {chat_with_memories(user_input)}")
+
+if __name__ == "__main__":
+    main()
 ```

+# mem0 CLI
+
+The official command-line interface for [mem0](https://mem0.ai) — the memory layer for AI agents. Works with the Mem0 Platform API. Available in Python and Node.js.
+
+> **For AI agents:** pass `--agent` (or `--json`) on any command for structured JSON output purpose-built for tool loops — sanitized fields, no colors or spinners, errors as JSON. See [Agent mode](#agent-mode) below.
+
+## Installation
+
+```bash
+npm install -g @mem0/cli
+```
+
+```bash
+pip install mem0-cli
+```
+
+Both packages install a `mem0` binary with identical behavior.
+
+## Quick start
+
+```bash
+# Interactive setup wizard
+mem0 init
+
+# Or login via email (get a new API key)
+mem0 init --email alice@company.com
+
+# Or authenticate with an existing API key
+mem0 init --api-key m0-xxx
+
+# Add a memory
+mem0 add "I prefer dark mode and use vim keybindings" --user-id alice
+
+# Search memories
+mem0 search "What are Alice's preferences?" --user-id alice
+
+# List all memories for a user
+mem0 list --user-id alice
+
+# Update a memory
+mem0 update <memory-id> "I switched to light mode"
+
+# Delete a memory
+mem0 delete <memory-id>
+```
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `mem0 init` | Setup wizard — login via email or configure API key manually |
+| `mem0 add` | Add a memory from text, JSON messages, a file, or stdin |
+| `mem0 search` | Search memories using natural language |
+| `mem0 list` | List memories with optional filters and pagination |
+| `mem0 get` | Retrieve a specific memory by ID |
+| `mem0 update` | Update the text or metadata of a memory |
+| `mem0 delete` | Delete a memory, all memories for a scope, or an entity |
+| `mem0 import` | Bulk import memories from a JSON file |
+| `mem0 config` | View or modify CLI configuration |
+| `mem0 entity` | List or delete entities (users, agents, apps, runs) |
+| `mem0 event` | Inspect background processing events (bulk deletes, large add jobs) |
+| `mem0 status` | Verify API connection and display current project |
+| `mem0 version` | Print the CLI version |
+
+Run `mem0 <command> --help` for detailed usage on any command.
+
+## 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
+```
+
+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`) |
+
+## 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`) |
+
+## Implementations
+
+| Language | Directory | Package | Docs |
+|----------|-----------|---------|------|
+| TypeScript | [`node/`](./node/) | `@mem0/cli` | [README](./node/README.md) |
+| Python | [`python/`](./python/) | `mem0-cli` | [README](./python/README.md) |

+# mem0 CLI (Node.js)
+
+The official command-line interface for [mem0](https://mem0.ai) — the memory layer for AI agents. TypeScript implementation.
+
+> **Built for AI agents.** Pass `--agent` (or `--json`) as a global flag on any command to get structured JSON output optimized for programmatic consumption — sanitized fields, no colors or spinners, and errors as JSON too.
+
+## Prerequisites
+
+- Node.js **18+**
+- pnpm (`npm install -g pnpm`) — for development only
+
+## Installation
+
+```bash
+npm install -g @mem0/cli
+```
+
+## Quick start
+
+```bash
+# Interactive setup wizard
+mem0 init
+
+# Or login via email
+mem0 init --email alice@company.com
+
+# Or authenticate with an existing API key
+mem0 init --api-key m0-xxx
+
+# Add a memory
+mem0 add "I prefer dark mode and use vim keybindings" --user-id alice
+
+# Search memories
+mem0 search "What are Alice's preferences?" --user-id alice
+
+# List all memories for a user
+mem0 list --user-id alice
+
+# Get a specific memory
+mem0 get <memory-id>
+
+# Update a memory
+mem0 update <memory-id> "I switched to light mode"
+
+# Delete a memory
+mem0 delete <memory-id>
+```
+
+## Commands
+
+### `mem0 init`
+
+Interactive setup wizard. Prompts for your API key and default user ID.
+
+```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).
+
+```bash
+mem0 init --api-key m0-xxx --user-id alice --force
+```
+
+| Flag | Description |
+|------|-------------|
+| `--api-key` | API key (skip prompt) |
+| `-u, --user-id` | Default user ID (skip prompt) |
+| `--email` | Login via email verification code |
+| `--code` | Verification code (use with `--email` for non-interactive login) |
+| `--force` | Overwrite existing config without confirmation |
+
+### `mem0 add`
+
+Add a memory from text, a JSON messages array, a file, or stdin.
+
+```bash
+mem0 add "I prefer dark mode" --user-id alice
+mem0 add --file conversation.json --user-id alice
+echo "Loves hiking on weekends" | mem0 add --user-id alice
+```
+
+| Flag | Description |
+|------|-------------|
+| `-u, --user-id` | Scope to a user |
+| `--agent-id` | Scope to an agent |
+| `--messages` | Conversation messages as JSON |
+| `-f, --file` | Read messages from a JSON file |
+| `-m, --metadata` | Custom metadata as JSON |
+| `--categories` | Categories (JSON array or comma-separated) |
+| `--graph / --no-graph` | Enable or disable graph memory extraction |
+| `-o, --output` | Output format: `text`, `json`, `quiet` |
+
+### `mem0 search`
+
+Search memories using natural language.
+
+```bash
+mem0 search "dietary restrictions" --user-id alice
+mem0 search "preferred tools" --user-id alice --output json --top-k 5
+```
+
+| Flag | Description |
+|------|-------------|
+| `-u, --user-id` | Filter by user |
+| `-k, --top-k` | Number of results (default: 10) |
+| `--threshold` | Minimum similarity score (default: 0.3) |
+| `--rerank` | Enable reranking |
+| `--keyword` | Use keyword search instead of semantic |
+| `--filter` | Advanced filter expression (JSON) |
+| `--graph / --no-graph` | Enable or disable graph in search |
+| `-o, --output` | Output format: `text`, `json`, `table` |
+
+### `mem0 list`
+
+List memories with optional filters and pagination.
+
+```bash
+mem0 list --user-id alice
+mem0 list --user-id alice --category preferences --output json
+mem0 list --user-id alice --after 2024-01-01 --page-size 50
+```
+
+| Flag | Description |
+|------|-------------|
+| `-u, --user-id` | Filter by user |
+| `--page` | Page number (default: 1) |
+| `--page-size` | Results per page (default: 100) |
+| `--category` | Filter by category |
+| `--after` | Created after date (YYYY-MM-DD) |
+| `--before` | Created before date (YYYY-MM-DD) |
+| `-o, --output` | Output format: `text`, `json`, `table` |
+
+### `mem0 get`
+
+Retrieve a specific memory by ID.
+
+```bash
+mem0 get 7b3c1a2e-4d5f-6789-abcd-ef0123456789
+mem0 get 7b3c1a2e-4d5f-6789-abcd-ef0123456789 --output json
+```
+
+### `mem0 update`
+
+Update the text or metadata of an existing memory.
+
+```bash
+mem0 update <memory-id> "Updated preference text"
+mem0 update <memory-id> --metadata '{"priority": "high"}'
+echo "new text" | mem0 update <memory-id>
+```
+
+### `mem0 delete`
+
+Delete a single memory, all memories for a scope, or an entire entity.
+
+```bash
+# Delete a single memory
+mem0 delete <memory-id>
+
+# Delete all memories for a user

+
+# Delete all memories project-wide
+mem0 delete --all --project --force
+
+# Preview what would be deleted
+mem0 delete --all --user-id alice --dry-run
+```
+
+| 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.
+
+## Development
+
+```bash
+cd cli/node
+pnpm install
+
+# Development mode (runs TypeScript directly, no build needed)
+pnpm dev --help
+pnpm dev add "test memory" --user-id alice
+pnpm dev search "test" --user-id alice
+
+# Or build first, then run the compiled JS
+pnpm build
+node dist/index.js --help
+```

+# Development
+
+## Prerequisites
+
+- Node.js **18+**
+- pnpm (`npm install -g pnpm`)
+
+## Setup
+
+From the `node/` directory:
+
+```bash
+pnpm install
+```
+
+## Running the CLI
+
+There are two ways to run the CLI during development:
+
+### Option 1: Development mode (no build needed)
+
+Uses `tsx` to run TypeScript directly. Pass CLI arguments after `pnpm dev`:
+
+```bash
+pnpm dev --help
+pnpm dev version
+pnpm dev add "test memory" --user-id alice
+pnpm dev search "test" --user-id alice
+pnpm dev config show
+```
+
+> **Note:** Do NOT use `pnpm dev -- --help`. With pnpm, arguments pass through directly — adding `--` inserts a literal `--` that breaks the CLI parser.
+
+### Option 2: Build and run compiled JS
+
+```bash
+# Build first
+pnpm build
+
+# Run the compiled CLI
+node dist/index.js --help
+node dist/index.js version
+node dist/index.js add "test memory" --user-id alice
+```
+
+### Option 3: Link globally (makes `mem0` available system-wide)
+
+```bash
+pnpm build
+pnpm link --global
+
+# Now use it like a normal CLI
+mem0 --help
+mem0 version
+```
+
+> **Warning:** If you also have the Python CLI installed, both register the `mem0` command. The last one linked/installed wins. Unlink with `pnpm unlink --global`.
+
+## Build
+
+```bash
+pnpm build
+```
+
+The compiled output is in `dist/`.
+
+## Run tests
+
+```bash
+# Run all tests
+pnpm test
+
+# Watch mode
+pnpm test:watch
+```
+
+## Lint
+
+```bash
+# Check
+pnpm lint
+
+# Auto-fix
+pnpm lint:fix
+```
+
+## Type checking
+
+```bash
+pnpm typecheck
+```

+ * Design:

+ *  - Atomic writes (tmp + rename) so a crash mid-write doesn't corrupt
+ *  - Idempotent — re-running with the same key is a no-op

+# mem0 CLI (Python)
+
+The official command-line interface for [mem0](https://mem0.ai) — the memory layer for AI agents. Python implementation.
+
+> **Built for AI agents.** Pass `--agent` (or `--json`) as a global flag on any command to get structured JSON output optimized for programmatic consumption — sanitized fields, no colors or spinners, and errors as JSON too.
+
+## Prerequisites
+
+- Python **3.10+**
+
+## Installation
+
+### Using pipx (recommended)
+
+```bash
+pipx install mem0-cli
+```
+
+### Using pip
+
+```bash
+pip install mem0-cli
+```
+
+> **Note:** On macOS with Homebrew Python, `pip install` outside a virtual environment will fail with an `externally-managed-environment` error ([PEP 668](https://peps.python.org/pep-0668/)). Use `pipx` instead, or install inside a virtual environment.
+
+## Quick start
+
+```bash
+# Interactive setup wizard
+mem0 init
+
+# Or login via email
+mem0 init --email alice@company.com
+
+# Or authenticate with an existing API key
+mem0 init --api-key m0-xxx
+
+# Add a memory
+mem0 add "I prefer dark mode and use vim keybindings" --user-id alice
+
+# Search memories
+mem0 search "What are Alice's preferences?" --user-id alice
+
+# List all memories for a user
+mem0 list --user-id alice
+
+# Get a specific memory
+mem0 get <memory-id>
+
+# Update a memory
+mem0 update <memory-id> "I switched to light mode"
+
+# Delete a memory
+mem0 delete <memory-id>
+```
+
+## Commands
+
+### `mem0 init`
+
+Interactive setup wizard. Prompts for your API key and default user ID.
+
+```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).
+
+```bash
+mem0 init --api-key m0-xxx --user-id alice --force
+```
+
+| Flag | Description |

+
+### `mem0 import`
+
+Bulk import memories from a JSON file.
+
+```bash
+mem0 import data.json --user-id alice

+mem0 config set user_id bob   # Set a value
+```
+
+### `mem0 entity`
+

+
+```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

+
+```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.

+# Development
+
+## Prerequisites
+
+- Python **3.10+**
+- `make` (optional — you can use plain Python commands instead)
+
+All commands below should be run from the `python/` directory:
+
+```bash
+cd python
+```
+
+## Setup
+
+### Using Make (recommended)
+
+All `make` targets automatically create a virtual environment (`.venv/`) and install the required dependencies — no manual setup needed.
+
+```bash
+# Install the CLI in editable mode
+make install
+
+# Install with dev tools (tests + linting)
+make dev
+```
+
+### Using Python directly
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+python -m pip install -U pip
+
+# Install in editable mode
+pip install -e .
+
+# With dev tools
+pip install -e ".[dev]"
+```
+
+## Make targets
+
+| Target              | Description                                      |
+| ------------------- | ------------------------------------------------ |
+| `make install`      | Create venv and install the CLI (editable mode)  |
+| `make dev`          | Create venv and install CLI + dev dependencies   |
+| `make test`         | Run all tests (installs dev deps if needed)      |
+| `make lint`         | Run linter and format check                      |
+| `make format`       | Auto-fix lint issues and format code             |
+| `make build`        | Build distribution packages                      |
+| `make clean`        | Remove `dist/`                                   |
+| `make publish`      | Build and publish to PyPI                        |
+| `make publish-test` | Build and publish to Test PyPI                   |
+| `make shell`        | Open a new shell with the venv activated         |
+
+## Run tests
+
+```bash
+# Using Make
+make test
+
+# Using Python directly
+pytest
+
+# Run a specific test file
+pytest tests/test_cli_integration.py
+
+# Run a single test
+pytest -k test_help
+```
+
+## Run the CLI
+
+```bash
+# Using Make — drop into an activated shell
+make shell
+mem0 --help
+
+# Using Python directly (with venv activated)
+source .venv/bin/activate
+mem0 --help
+mem0 version
+
+# Or run without activating
+.venv/bin/mem0 --help
+```
+
+## Lint
+
+```bash
+# Using Make
+make lint      # check only
+make format    # auto-fix
+
+# Using Python directly (with venv activated)
+ruff check .
+ruff format .
+```
+
+## Optional extras
+
+### OSS integration
+
+```bash
+pip install -e ".[oss]"
+```
