-This installs the MCP server and the Mem0 SDK skill. Codex uses the skill-based memory protocol instead of lifecycle hooks.
+Options A, B, and C above install the MCP server and the Mem0 SDK skill.
+
+**Optional — enable lifecycle hooks**
+
+Codex only discovers hooks at `~/.codex/hooks.json` or `<repo>/.codex/hooks.json` ([docs](https://developers.openai.com/codex/hooks)) — there is no plugin-host mechanism that auto-wires hooks from an installed plugin. To opt in, run the installer once after installing the plugin:
+
+```bash
+python3 /path/to/mem0-plugin/scripts/install_codex_hooks.py
+```
+
+This merges three entries into `~/.codex/hooks.json` with absolute paths pointing into the plugin directory:
+
+| Event | What it does |
+|-------|--------------|
+| `SessionStart` | Loads prior memories as bootstrap context |
+| `UserPromptSubmit` | Injects relevant memories into the prompt |
+| `Stop` | Reminds the agent to persist learnings at turn end |
+
+Re-running the installer is idempotent (replaces the Mem0 entries rather than duplicating) and preserves any other hooks you have. To remove: `python3 scripts/install_codex_hooks.py --uninstall`.
+
+Codex hooks also require the `codex_hooks` feature flag in `~/.codex/config.toml`:
+
+```toml
+[features]
+codex_hooks = true
+```
+
+The installer prints a reminder if the flag isn't set. Restart Codex after editing the config.

+- **Lifecycle Hooks** — Automatic memory capture at key points. Claude Code and Cursor wire hooks up natively when the plugin is installed (session start, context compaction, task completion, session end). Codex hooks are opt-in via a one-time installer (`scripts/install_codex_hooks.py`) that writes entries into `~/.codex/hooks.json` for `SessionStart`, `UserPromptSubmit`, and `Stop`.
 - **Mem0 SDK Skill** — Guides the AI on how to integrate the Mem0 SDK (Python & TypeScript) into your applications.
 - **Memory Protocol Skill** — Codex-specific skill that instructs the agent to retrieve relevant memories at task start, store learnings on completion, and capture session state before context loss. Replaces lifecycle hooks on platforms that don't support them.

 ## Common edge cases

- **Search returns empty:** Memories process asynchronously. Wait 2-3s after `add()` before searching. Also verify `user_id` matches exactly (case-sensitive).
+- **Search returns empty:** Memories process asynchronously. Wait 2-3s after `add()` before searching. Also verify `user_id` matches exactly (case-sensitive) and use `filters={"user_id": "..."}` syntax.
 - **AND filter with user_id + agent_id returns empty:** Entities are stored separately. Use `OR` instead, or query separately.
 - **Duplicate memories:** Don't mix `infer=True` (default) and `infer=False` for the same data. Stick to one mode.
 - **Wrong import:** Always use `from mem0 import MemoryClient` (or `AsyncMemoryClient` for async). Do not use `from mem0 import Memory`.
- **Immutable memories:** Cannot be updated or deleted once created. Use `client.history(memory_id)` to track changes over time.
+- **v3 defaults:** `top_k=20`, `threshold=0.1`, `rerank=False`. Adjust as needed for your use case.
+
+## v2 Compatibility
+
+If you're using SDK v2.x, note these differences:
+- **Entity IDs:** Pass `user_id` as top-level kwarg to `search()` instead of inside `filters`
+- **Defaults:** `top_k=100`, no threshold, `rerank=True`
+- **Graph memory:** Available via `enable_graph=True`

+# Python vs TypeScript SDK Differences
+
+Quick-reference cheatsheet for developers working across both Mem0 SDKs.
+
+## Constructor
+
+| Aspect | Python | TypeScript |
+|--------|--------|------------|
+| Import (Platform) | `from mem0 import MemoryClient` | `import MemoryClient from 'mem0ai'` |
+| Import (OSS) | `from mem0 import Memory` | `import { Memory } from 'mem0ai/oss'` |
+| Constructor | `MemoryClient(api_key="m0-xxx")` | `new MemoryClient({ apiKey: 'm0-xxx' })` |
+| Required param | `api_key` (positional or kwarg) | `apiKey` (in options object) |
+
+Both read from `MEM0_API_KEY` env var if no key provided.
+
+## Method Naming
+
+| Operation | Python | TypeScript |
+|-----------|--------|------------|
+| Add | `add()` | `add()` |
+| Search | `search()` | `search()` |
+| Get | `get()` | `get()` |
+| Get all | `get_all()` | `getAll()` |
+| Update | `update()` | `update()` |
+| Delete | `delete()` | `delete()` |
+| Delete all | `delete_all()` | `deleteAll()` |
+| History | `history()` | `history()` |
+| Batch update | `batch_update()` | `batchUpdate()` |
+| Batch delete | `batch_delete()` | `batchDelete()` |
+| List users | `users()` | `users()` |
+| Delete users | `delete_users()` | `deleteUsers()` |
+| Get project | `project.get()` | `getProject()` |
+| Update project | `project.update()` | `updateProject()` |
+| Create webhook | `create_webhook()` | `createWebhook()` |
+| Get webhooks | `get_webhooks()` | `getWebhooks()` |
+| Update webhook | `update_webhook()` | `updateWebhook()` |
+| Delete webhook | `delete_webhook()` | `deleteWebhook()` |
+| Create export | `create_memory_export()` | `createMemoryExport()` |
+| Get export | `get_memory_export()` | `getMemoryExport()` |
+| Feedback | `feedback()` | `feedback()` |
+
+**Rule:** Python uses `snake_case`, TypeScript uses `camelCase` for method names.
+
+## Parameter Passing
+
+```python
+# Python: kwargs
+client.add(messages, user_id="alice", metadata={"source": "chat"})
+client.search("query", filters={"user_id": "alice"}, top_k=5, rerank=True)
+```
+
+```typescript
+// TypeScript: options object with camelCase for top-level params, snake_case for filter keys
+await client.add(messages, { userId: 'alice', metadata: { source: 'chat' } });
+await client.search('query', { filters: { user_id: 'alice' }, topK: 5, rerank: true });
+```
+
+**v3:** Python uses `snake_case` everywhere. TypeScript uses `camelCase` for top-level params (`userId`, `topK`) but `snake_case` for filter keys (`user_id`, `agent_id`).
+
+## Architectural Differences
+
+| Aspect | Python | TypeScript |
+|--------|--------|------------|
+| HTTP library | httpx | axios |
+| Default timeout | 300s | 60s |
+| Sync support | Yes (`MemoryClient`) | No (all async) |
+| Async support | Yes (`AsyncMemoryClient`) | All methods are async |
+| Project management | `client.project.*` (separate class) | `client.getProject()` / `client.updateProject()` |
+| Context manager | `async with AsyncMemoryClient()` | Not supported |
+
+## Platform Features: Python-only
+
+These methods exist in Python but not TypeScript:
+
+| Method | Description |
+|--------|-------------|
+| `get_summary(filters)` | Get summary of memories |
+| `reset()` | Delete ALL data (users + memories) |
+| `project.create(name)` | Create a new project |
+| `project.delete()` | Delete current project |
+| `project.get_members()` | List project members |
+| `project.add_member(email, role)` | Add member to project |
+| `project.update_member(email, role)` | Change member role |
+| `project.remove_member(email)` | Remove member |
+
+## Platform Features: TypeScript-only

+| `deleteUser(data)` | Convenience method for single entity deletion |
+| `ping()` | Health check endpoint |
+
+## OSS Config Naming
+
+| Python config key | TypeScript config key |
+|-------------------|----------------------|
+| `vector_store` | `vectorStore` |
+| `history_db_path` | `historyDbPath` |
+| `custom_instructions` | `customInstructions` |

+## OSS Scope Parameter Naming
+
+| Python | TypeScript |
+|--------|------------|
+| `user_id="alice"` | `userId: 'alice'` |
+| `agent_id="bot"` | `agentId: 'bot'` |
+| `run_id="session"` | `runId: 'session'` |
+
+## Entity ID Passing (v3)
+
+| Method | Python | TypeScript |
+|--------|--------|------------|
+| add() | Top-level: `user_id="alice"` | Top-level: `{ userId: 'alice' }` |
+| search() | In filters: `filters={"user_id": "alice"}` | In filters: `{ filters: { user_id: 'alice' } }` |
+| get_all() | In filters: `filters={"user_id": "alice"}` | In filters: `{ filters: { user_id: 'alice' } }` |
+
+## Common Gotcha
+
+When searching/filtering, both Python and TypeScript use `snake_case` for filter keys. TypeScript only uses `camelCase` for top-level method parameters:
+
+```python
+# Python - snake_case in filters
+results = client.search("query", filters={"user_id": "alice"})
+```
+
+```typescript
+// TypeScript - snake_case in filters, camelCase for top-level params
+const results = await client.search('query', { filters: { user_id: 'alice' }, topK: 20 });

+## Key Differences: Platform vs OSS
+
+| Aspect | Platform (`MemoryClient`) | OSS (`Memory`) |
+|--------|--------------------------|----------------|
+| **Import** | `import MemoryClient from 'mem0ai'` | `import { Memory } from 'mem0ai/oss'` |
+| **Auth** | API key required (`MEM0_API_KEY`) | No API key -- config-based |
+| **Execution** | API calls to `api.mem0.ai` | Local execution |
+| **Infrastructure** | Fully managed | Self-managed vector DB, embedder, LLM |
+| **Param style** | Top-level: `camelCase` (`userId`, `topK`), filter keys: `snake_case` (`user_id`) | Top-level: `camelCase` (`userId`, `topK`), filter keys: `snake_case` (`user_id`) |
+| **Batch ops** | `batchUpdate`, `batchDelete` | Not available |
+| **Webhooks** | Full CRUD | Not available |
+| **Export** | `createMemoryExport` | Not available |
+| **Feedback** | `feedback()` | Not available |
+| **Project mgmt** | `getProject`, `updateProject` | Not available |
+| **User listing** | `users()`, `deleteUser()` | Not available |
+| **History** | Platform-managed | SQLite (configurable) |
+
+---
+
+## v2 Compatibility
+
+If you're using SDK v2.x:
+
+**Naming Changes:**
+- Top-level params now use camelCase: `topK`, `rerank` (not `top_k`)
+- Filter keys use snake_case: `user_id`, `agent_id`
+- OSS: `limit` renamed to `topK`
+
+**API Changes:**
+```typescript
+// v2 - top-level entity IDs, snake_case
+await client.search("query", { user_id: "alice", top_k: 20 });
+
+// v3 - filters object with snake_case keys, camelCase top-level params
+await client.search("query", { filters: { user_id: "alice" }, topK: 20 });
+```
+
+**Default Changes:**
+| Param | v2 | v3 |
+|-------|----|----|
+| `topK` | 100 | 20 |
+| `threshold` | none | 0.1 |
+| `rerank` | true | false |
+
+**Removed:**
+- `OutputFormat` and `API_VERSION` enums
+- `organizationId`, `projectId` from constructor
+- `enableGraph`, `asyncMode`, `outputFormat`, `immutable`, `expirationDate`, `filterMemories`, `batchSize`, `forceAddOnly`, `includes`, `excludes`, `keywordSearch`

+```
+
+**Import:** `from mem0 import Memory` (NOT `MemoryClient` -- that is the Platform client)
+
+### Configuration
+
+```python
+config = {
+    "llm": {
+        "provider": "openai",        # openai, groq, azure, ollama, lmstudio, google, anthropic, mistral
+        "config": {

+        "config": {
+            "collection_name": "my_memories",
+            "host": "localhost",
+            "port": 6333,
+        }
+    },
+    "history_db_path": "history.db",              # SQLite path for change history
+    "custom_instructions": "...",                  # Custom LLM prompt for extraction
+}
+
+m = Memory.from_config(config)
+```
+
+### Context Manager
+
+```python
+with Memory(config) as m:
+    m.add("I prefer dark mode", user_id="alice")
+    results = m.search("preferences", filters={"user_id": "alice"})
+# SQLite connections released automatically
+```
+
+### Methods
+
+All methods mirror the Platform client but run locally:
+
+#### add(messages, *, user_id, agent_id, run_id, metadata, infer=True)
+
+```python
+m.add("I'm a vegetarian", user_id="alice")
+m.add([
+    {"role": "user", "content": "I like hiking"},
+    {"role": "assistant", "content": "Great outdoor activity!"}
+], user_id="alice")
+```
+
+At least one of `user_id`, `agent_id`, `run_id` required.
+
+**Returns:** `{"results": [...], "relations": [...]}`
+
+#### search(query, *, filters=None, top_k=20, threshold=0.1, rerank=False)
+
+```python
+results = m.search("dietary preferences", filters={"user_id": "alice"}, top_k=5)
+```
+
+Entity IDs (`user_id`, `agent_id`, `run_id`) must be passed inside the `filters` dict.
+
+Supports filter operators: `eq`, `ne`, `in`, `nin`, `gt`, `gte`, `lt`, `lte`, `contains`, `not_contains`.
+
+#### get(memory_id) / get_all(**kwargs) / update(memory_id, data, metadata=None) / delete(memory_id) / delete_all(**kwargs) / history(memory_id)
+
+Same interface as Platform client.
+
+#### reset()
+
+Clear the entire vector store collection and history database. Recreates the vector store.
+
+```python
+m.reset()
+```
+
+#### close()
+
+Release SQLite connections. Called automatically when using context manager.
+
+### AsyncMemory
+
+```python
+from mem0 import AsyncMemory
+
+m = AsyncMemory(config)
+await m.add("text", user_id="alice")
+results = await m.search("query", filters={"user_id": "alice"})
+```

- `delete_all()` without filters raises error to prevent accidental data loss
-
-### History tracking
- `client.history(memory_id)` returns version timeline
- Shows all changes: `{previous_value, new_value, action, timestamps}`

+- **Entity matching** (entity graph boost)

-Expands results to include memories with specific terms, names, and technical keywords.

- Accuracy: Significantly improved
+- Default: `False` (was `True` in v2)

-## Graph Memory
+## Entity Linking

-Entity-level knowledge graph that creates relationships between memories.
+v3 replaces graph memory with built-in entity linking. Entities (proper nouns, quoted text, compound noun phrases) are automatically extracted and linked across memories.

 ### How It Works

-1. **Extraction**: LLM analyzes conversation and identifies entities and relationships
-2. **Storage**: Embeddings go to vector store; entity nodes and edges go to graph store
-3. **Retrieval**: Vector search returns semantic matches; graph relations are appended to results
+1. **Extraction**: During `add()`, entities are automatically extracted from memory text
+2. **Storage**: Entities are stored in a parallel collection (`{collection}_entities`)
+3. **Retrieval**: During `search()`, query entities are matched and used to boost relevant memories

-Graph relations **augment** vector results without reordering them. Vector similarity always determines hit sequence.
+Entity linking is automatic — no configuration required. The boost is folded into the combined `score` on each result.

-### Enabling Graph Memory
+### v2 Migration Note

-**Per request:**
-```python
-client.add(messages, user_id="alice", enable_graph=True)
-client.search("query", user_id="alice", enable_graph=True)
-client.get_all(filters={"AND": [{"user_id": "alice"}]}, enable_graph=True)
-```
+If you were using `enable_graph=True` in v2:
+- Remove `enable_graph` from all API calls
+- Remove `graph_store` from OSS configuration
+- Entity relationships are now consumed through retrieval ranking, not exposed as a separate `relations` array

-**Project-level (default for all operations):**
-```python
-client.project.update(enable_graph=True)
-```
-
-```javascript
-await client.updateProject({ enable_graph: true });
-```
-
-### Relation Structure
-
-Each relation in the response contains:
-
-| Field | Type | Description |
-|-------|------|-------------|
-| `source` | string | Source entity name |
-| `source_type` | string | Source entity type (e.g., "Person") |
-| `relationship` | string | Relationship label (e.g., "lives_in") |
-| `target` | string | Target entity name |
-| `target_type` | string | Target entity type (e.g., "City") |
-| `score` | number | Confidence score |
-
-**Example:**
-```json
-{
-  "relations": [
-    {

-### Technical Notes
-
- Graph Memory adds processing time; see docs for current plan availability
- Works optimally with rich conversation histories containing entity relationships
- Best suited for long-running assistants tracking evolving information
- Graph writes and reads toggle independently per request
- Multi-agent context supported via `user_id`, `agent_id`, `run_id` scoping
- Add operations are asynchronous; graph metadata may not be immediately available
+See the [v2 to v3 migration guide](https://docs.mem0.ai/migration/oss-v2-to-v3) for details.

+## v2 to v3 Migration
+
+### Breaking Changes in v3
+
+**1. Entity IDs in search() and getAll()**
+
+v3 requires entity IDs (`user_id`, `agent_id`, `run_id`) inside `filters` instead of as top-level parameters:
+
+```python
+# v2 (deprecated)
+client.search("query", user_id="alice")
+client.get_all(user_id="alice")
+
+# v3
+client.search("query", filters={"user_id": "alice"})
+client.get_all(filters={"user_id": "alice"})
+```
+
+```typescript
+// v2 (deprecated)
+await client.search("query", { user_id: "alice" });
+await client.getAll({ user_id: "alice" });
+
+// v3
+await client.search("query", { filters: { user_id: "alice" } });
+await client.getAll({ filters: { user_id: "alice" } });
+```
+
+**2. TypeScript Parameter Naming**
+
+v3 TypeScript uses camelCase for all parameters:
+
+| v2 | v3 |
+|----|-----|
+| `user_id` | `userId` |
+| `agent_id` | `agentId` |
+| `run_id` | `runId` |
+| `top_k` | `topK` |
+| `page_size` | `pageSize` |
+
+**3. Default Values Changed**
+
+| Parameter | v2 Default | v3 Default |
+|-----------|------------|------------|
+| `threshold` | 0.3 | 0.1 |
+| `rerank` | (not specified) | `false` |
+
+**4. Removed Parameters**
+
+The following parameters are no longer supported:
+
+| Parameter | Status |
+|-----------|--------|
+| `enable_graph` | Removed from add/search/getAll |
+| `keyword_search` | Removed from search |
+| `filter_memories` | Removed |
