name: CI Gate
# Single required status check for all PRs.
#
# Path-filtered CI workflows can't be marked as required in branch
# protection: on a PR that doesn't touch their paths they never report, and
# the required check hangs at "Expected" forever. This gate solves that. It
# runs on every PR, detects which packages changed, calls only the relevant
# package CI workflows (as reusable workflows), and the final "CI Gate" job
# reports the aggregate result — success when every invoked pipeline passed
# (skipped pipelines are fine), failure when any failed.
#
# Branch protection should require exactly one status check: "CI Gate".
#
# Package CI workflows keep their own push-to-main and workflow_dispatch
# triggers; only their pull_request triggers moved here. To wire in a new
# package: add a filter under the `changes` job, a call job that `uses:` the
# package workflow, and list the call job in the gate's `needs`.

### Adding a New Provider
@@ -402,19 +404,36 @@ To add a new LLM, embedding, vector store, or reranker provider:
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.

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.

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.

<Update label="2026-06-12" description="v1.0.13">
**Fixes:**
- **Custom categories payload:** `customCategories` (a `Record<string, string>` map) is now converted via the new `customCategoryMapToList()` helper into the `Array<Record<string, string>>` shape the Mem0 SDK expects on `add` calls — previously the raw object was passed as `custom_categories` and silently ignored ([#5345](https://github.com/mem0ai/mem0/pull/5345))
- **Skip runtime setup during metadata registration:** `register()` now detects `registrationMode === "cli-metadata"`, registers only the CLI commands, and returns early — avoiding backend initialization, service/tool registration, and hook installation during OpenClaw's metadata-only registration pass ([#5383](https://github.com/mem0ai/mem0/pull/5383))
**Security:**
- Bumped `mem0ai` from `3.0.3` to `3.0.7` (latest Node SDK) — includes the transitive axios CVE remediation shipped in `3.0.6` ([#5460](https://github.com/mem0ai/mem0/pull/5460))
- Added pnpm override `uuid@<11.1.1` → `>=11.1.1` to resolve an open MEDIUM Dependabot alert ([#5489](https://github.com/mem0ai/mem0/pull/5489))
**Improvements:**
- **Repo consolidation:** Plugin moved from repo-root `openclaw/` to `integrations/openclaw/`; `package.json` `repository.directory` updated to match so npm provenance links to the correct subdirectory ([#5491](https://github.com/mem0ai/mem0/pull/5491))
**Tests:**
- Added `customCategoryMapToList` unit tests and a `PlatformProvider` test asserting `custom_categories` is passed to the Mem0 SDK as a list ([#5345](https://github.com/mem0ai/mem0/pull/5345))
- Added a regression test asserting `cli-metadata` registration registers only CLI commands and triggers no runtime side effects ([#5383](https://github.com/mem0ai/mem0/pull/5383))
</Update>
<Update label="2026-06-02" description="v1.0.12">
**Docs:**
- **Agent Mode onboarding:** README now documents an autonomous setup path for AI agents — `mem0 init --agent --json` mints an evaluation Mem0 API key with no email, OTP, or browser and exports it as `MEM0_API_KEY` for `openclaw mem0 init`; a human owner can later run `mem0 init --email <email>` to claim ownership without disrupting the agent ([#5123](https://github.com/mem0ai/mem0/pull/5123))
**Security:**
- Added pnpm overrides to remediate advisories in transitive dependencies: `langsmith@<0.6.0` → `^0.6.0`, `picomatch@<2.3.2` → `^2.3.2`, `vite` → `^8.0.5`, and `@qdrant/js-client-rest` → `^1.18.0` ([#5294](https://github.com/mem0ai/mem0/pull/5294))
**Dependencies:**
- Bumped `mem0ai` from `3.0.2` to `3.0.3` ([#5212](https://github.com/mem0ai/mem0/pull/5212))
- Bumped dev dependencies `@vitest/coverage-v8` and `vitest` from `^4.0.18` to `^4.1.7`; added `vite@^8.0.5` and `@qdrant/js-client-rest@^1.18.0` ([#5294](https://github.com/mem0ai/mem0/pull/5294))

5. **Entity Linking** — Identify entities (proper nouns, quoted text, compound noun phrases) and link them across memories
5. **Graph Memory (Entity Linking)**: Identify entities (proper nouns, quoted text, compound noun phrases) and link them across memories into a graph
Memories are distributed across three storage layers, each tuned for a specific retrieval pattern:
| Store | Contents | Purpose |
|---|---|---|
| **Vector Database** | Memory text, embeddings, metadata (timestamps, hash, categories, attributed_to) | Primary fact storage + semantic retrieval |
| **Entity Store** | Entities + embeddings + linked memory IDs | Entity-based retrieval boost |
| **Graph / Entity Store** | Entities + embeddings + linked memory IDs | Graph connections across memories + entity-based retrieval boost |
| **SQL Database** | History log (ADD events) + rolling message window | Audit trail + extraction dedup context |

| `delete_entities` | Delete a user/agent/app/run entity and its memories |
| `list_entities` | List users/agents/apps/runs stored in Mem0 |
## Memory scope
`search_memories`, `get_memories`, `add_memory`, and `delete_all_memories` accept an optional **`scope`** that controls how widely they read or write:
| Scope | Reads | Writes |
|-------|-------|--------|
| `project` *(default)* | this repo (`user_id` + `app_id`) | this repo |
| `session` | this run only (`+ run_id`) | this run |
| `global` | **all your projects in the workspace** (`app_id: "*"`) | user-wide |
Just ask naturally — e.g. *"search my memories across all my projects"* — and the agent passes `scope: "global"`. For normal questions it stays scoped to the current project automatically.
To change the **default** scope (used when no scope is passed), run the `/mem0-scope` skill:
```
/mem0-scope # show the current default scope + identity
/mem0-scope global # save & search across all your projects by default
/mem0-scope project # back to repo-only (the default)
```
The default persists in `~/.mem0/settings.json` (`default_scope`) and is read fresh on each memory operation, so a change applies immediately — no restart. `delete_all_memories` always requires an explicit `scope: "global"` to delete user-wide, so changing the default can't trigger a cross-project wipe.
The project id (`app_id`) is derived from your git remote (`owner-repo`), falling back to the git repo's root directory name, then the current directory. Launch OpenCode from inside your repo so memories scope to the project rather than your home directory.
## Lifecycle Hooks
The plugin uses the [mem0ai](https://www.npmjs.com/package/mem0ai) TypeScript SDK directly — pure TypeScript, no Python, no shell scripts.
| OpenCode Event | Hook | What happens |
|----------------|------|-------------|
| `config` | **Config** | Registers the `/mem0-*` slash commands (`config.command`) and adds the plugin's own `opencode-skills/` dir to OpenCode's `skills.paths` for in-place skill discovery (no copying) |
| `chat.message` | **Chat message** | Searches prior memories on session start, searches relevant memories before each prompt, auto-captures learnings periodically |
| `tool.execute.before` | **Pre-tool** | Blocks MEMORY.md writes, injects `user_id`/`app_id` on mem0 tool calls |
| `tool.execute.after` | **Post-tool** | Tracks stats, scans Bash errors and pre-fetches related error memories |
| `experimental.chat.system.transform` | **System transform** | Injects memory context (session memories, search results, error lookups) into the system prompt |
| `tool.execute.before` | **Pre-tool** | Blocks MEMORY.md writes, steering them to the `add_memory` tool |
| `tool.execute.after` | **Post-tool** | Scans Bash errors and pre-fetches related error memories |
| `experimental.chat.messages.transform` | **Messages transform** | Injects memory context (session memories, search results, error lookups) into the prompt |
| `experimental.session.compacting` | **Compaction** | Stores session state memory, then injects prior memories into compaction context so nothing is lost |
| `shell.env` | **Shell env** | Exports `MEM0_USER_ID`, `MEM0_APP_ID`, `MEM0_SESSION_ID`, and `MEM0_BRANCH` to all shell executions |
## Auto-dream (memory consolidation)
The plugin can automatically consolidate stored memories — merging duplicates, dropping stale/sensitive entries, and rewriting vague ones — so your memory set stays clean over time. It runs at most once per session, and only when **all** gates pass:
- **Time** — at least `minHours` (default 24) since the last consolidation
- **Sessions** — at least `minSessions` (default 5) sessions since then
- **Memories** — at least `minMemories` (default 20) stored for the project
A filesystem lock (`~/.mem0/mem0-dream.lock`) keeps two sessions from consolidating at once. Tune the thresholds with a `dream` block in `~/.mem0/settings.json`, or disable entirely with `MEM0_DREAM=false`:
```json
{
"dream": { "enabled": true, "auto": true, "minHours": 24, "minSessions": 5, "minMemories": 20 }
}
```
If auto-dream hasn't run yet, it's almost always because a gate hasn't been met (most often too few memories). Run `/mem0-status` to see the exact gate progress (e.g. `sessions 2/5, memories 3/20`), `/mem0-dream` to consolidate **now** regardless of the gates, or lower the thresholds above.
## Troubleshooting
- **No tools appearing** — Restart OpenCode after installing
- **"Connection failed"** — Verify your key is set: `echo $MEM0_API_KEY`
- **Plugin not loading** — Run `opencode plugin @mem0/opencode-plugin` again, then restart
- **Hooks not firing** — Hooks require the plugin install (Option A). MCP-only installs don't include hooks.
- **Auto-dream never runs** — It's gated (time + sessions + memories). Run `/mem0-status` to see which gate is blocking, or `/mem0-dream` to consolidate now.
- **Wrong project name / memories not found** — The project id comes from your git remote; launch OpenCode from inside the repo (not your home directory). Check the resolved id with `/mem0-status`.

External graph **store** support has been removed from the open-source SDK and replaced by **built-in graph memory** (entity linking), which runs natively with no external dependencies.

- `enable_graph` / `enableGraph` config flag
- `graph_store` / `graphStore` configuration block (Neo4j, Memgraph, Kuzu, Apache AGE, Neptune)
- All graph memory code paths (~4000 lines)
- All external graph store code paths (~4000 lines)
**What replaces it:**
Entity linking extracts entities (proper nouns, quoted text, compound noun phrases) from every memory during the add pipeline and stores them in a parallel collection (`{collection}_entities`) inside your existing vector store. At search time, entities from the query are matched against this collection and used to boost relevant memories. The boost is folded into the combined `score` on each result.
Mem0 now builds the graph itself. It extracts entities (proper nouns, quoted text, compound noun phrases) from every memory during the add pipeline and stores them in a parallel collection (`{collection}_entities`) inside your existing vector store. Memories that share an entity are linked, and at search time entities from the query are matched against this collection to boost connected memories. The boost is folded into the combined `score` on each result.
**Migration:**
- Remove `enable_graph` / `enableGraph` from your config
- Remove the `graph_store` / `graphStore` block — it is no longer read
- Uninstall graph drivers (neo4j, memgraph, etc.) if you were using them only for Mem0
- No data migration is required. Entity linking activates automatically on the next `add()` call.
- Uninstall external graph drivers (neo4j, memgraph, etc.) if you were using them only for Mem0
- No data migration is required. Built-in graph memory activates automatically on the next `add()` call.
<Warning>
Graph relationships exposed via the old `relations` field on search results are no longer populated. Entity relationships are consumed indirectly through retrieval ranking, not exposed as a queryable graph structure. If your application depended on traversing graph relationships directly, you will need to redesign that part against the new API.
The old `relations` field on search results (populated by the external graph store) is no longer returned. Entity connections are now applied through retrieval ranking rather than exposed as a separate, directly traversable structure.

description: "Mem0 Platform builds a native graph linking people, places, and concepts across your memories, with no external graph database to provision."
icon: "circle-nodes"
iconType: "solid"
---
Mem0 Platform automatically organizes your memories into a **graph**: the **graph entities** mentioned across your memories (the people, places, organizations, and concepts they refer to) become nodes, and memories that share an entity are connected. This is how Mem0 reasons across separate facts, for example linking everything it knows about a person, a company, or a project, without you defining any schema.
Graph Memory is **built in**. There is no Neo4j, Memgraph, or other graph store to deploy, no connection strings to manage, and nothing to enable. It runs natively inside the platform and is always on.
<Info>
**Graph Memory matters when…**
- You ask entity-centric questions like "what do we know about Alice?" and expect facts pulled from many different conversations
- Your app needs multi-hop recall, connecting a fact in one memory to a related fact in another
- You previously used an external graph store and want the same cross-memory connections with zero infrastructure
</Info>
<Note>
**Graph entities vs. entity IDs.** The entities in your graph (people, places, and concepts extracted from memory text) are different from the *entity IDs* (`user_id`, `agent_id`, `app_id`, `run_id`) used to scope memories. Those are covered in [Entity-Scoped Memory](/platform/features/entity-scoped-memory).
</Note>
<Note>
Graph Memory is the native successor to Mem0's earlier graph store integration. Earlier versions connected an external graph database (Neo4j and others) and exposed a `relations` field. Mem0 now builds the graph itself from your memories. See [What changed from the external graph store](#what-changed-from-the-external-graph-store) below.
</Note>
## How it works
Graph Memory is built and used across the two phases of the memory pipeline: **extraction** (when you add memories) and **retrieval** (when you search).
### 1. Entities become nodes
Every time you add a memory, Mem0 extracts the **entities** it contains: the proper nouns, names, and key phrases that identify a specific person, place, organization, product, or concept (for example *Alice*, *San Francisco*, *Acme Corp*, *the Q1 roadmap*). Each distinct entity is stored once and embedded, so entities that refer to the same thing can be matched even when they are phrased differently.
### 2. Shared entities become connections
When the same entity appears in more than one memory, those memories are **linked** through that entity. Over time this forms a graph: a web of entities, each connecting all the memories that mention it. The connections are derived directly from your data. There is no relationship schema to define and nothing to label by hand.
### 3. The graph powers retrieval
At search time, Mem0 extracts the entities from your query and matches them against the graph. Memories connected to those entities receive a ranking boost, which is combined with semantic (vector) and keyword (BM25) scores into the single `score` returned on each result.
This is what lets Mem0 answer entity-centric and multi-hop questions: a query about *Alice* surfaces facts about Alice that live in completely different memories, because the graph connects them. The connecting-facts-across-memories behavior contributes to Mem0's gains on multi-hop and temporal benchmarks. See [Memory Evaluation](/core-concepts/memory-evaluation).
<Info>
Graph Memory affects **ranking**, not the response shape. Search results come back in the normal format with a combined `score`; there is no separate graph payload to parse.
</Info>
## What's in the graph
| Element | What it is |
| --- | --- |
| **Graph entity** (node) | A distinct person, place, organization, product, or concept extracted from your memories (e.g. *Alice*, *Acme Corp*). Distinct from the user/agent/app/run *entity IDs* used to scope memories. |
| **Memory node** | An individual memory (fact) stored for a user, agent, or session. |
| **Connection** | A link between an entity and every memory that mentions it. Two entities are related when they co-occur in one or more memories. |
Graph Memory captures **which entities your memories are about and how they connect through shared context**. It does not assign typed, labeled relationships between entities (it won't, for example, record a "manages" edge from one person to another); connections are inferred from co-occurrence rather than declared. This is what makes it schema-free and zero-configuration.
## Availability
Graph Memory is **automatic and included on all plans**. It activates on the new memory algorithm with no flag, no configuration, and no external dependencies. You don't need to do anything to benefit from it.
```python
from mem0 import MemoryClient
client = MemoryClient(api_key="your-api-key")
# Entities are extracted and linked into the graph automatically on add
client.add(
messages=[
{"role": "user", "content": "I work at Acme Corp with Alice on the Q1 roadmap"}
],
user_id="jordan",
)
# Entity matches from the query are used to connect and boost related memories
results = client.search(
query="who does jordan work with?",
filters={"user_id": "jordan"},
)
```
## What changed from the external graph store
Earlier versions of Mem0 offered graph memory by connecting an **external graph database** (Neo4j, Memgraph, Kuzu, Apache AGE, or Neptune) through an `enable_graph` flag and a `graph_store` configuration block. That integration has been replaced by **native, built-in Graph Memory**:
- **No external graph store.** The graph is built inside Mem0 from your memories. There is nothing to provision or connect.
- **Always on, all plans.** The `enable_graph` flag is no longer needed; Graph Memory is automatic. (If you still send the parameter, it is ignored.)
- **Connections power retrieval directly.** Entity connections are folded into the combined `score` on each result. The standalone `relations` field that the external graph store returned is no longer populated. If your application read that field, see the migration guide below.

# Mem0: Building Production‑Ready AI Agents with Scalable Long‑Term Memory
[![arXiv](https://img.shields.io/badge/arXiv-Paper-b31b1b.svg)](https://arxiv.org/abs/2504.19413)
[![Website](https://img.shields.io/badge/Website-Project-blue)](https://mem0.ai/research)
This repository contains the code and dataset for our paper: **Mem0: Building Production‑Ready AI Agents with Scalable Long‑Term Memory**.
## 📋 Overview
This project evaluates Mem0 and compares it with different memory and retrieval techniques for AI systems:
1. **Established LOCOMO Benchmarks**: We evaluate against five established approaches from the literature: LoCoMo, ReadAgent, MemoryBank, MemGPT, and A-Mem.
2. **Open-Source Memory Solutions**: We test promising open-source memory architectures including LangMem, which provides flexible memory management capabilities.
3. **RAG Systems**: We implement Retrieval-Augmented Generation with various configurations, testing different chunk sizes and retrieval counts to optimize performance.
4. **Full-Context Processing**: We examine the effectiveness of passing the entire conversation history within the context window of the LLM as a baseline approach.
5. **Proprietary Memory Systems**: We evaluate OpenAI's built-in memory feature available in their ChatGPT interface to compare against commercial solutions.
6. **Third-Party Memory Providers**: We incorporate Zep, a specialized memory management platform designed for AI agents, to assess the performance of dedicated memory infrastructure.
We test these techniques on the LOCOMO dataset, which contains conversational data with various question types to evaluate memory recall and understanding.
## 🔍 Dataset
The LOCOMO dataset used in our experiments can be downloaded from our Google Drive repository:
[Download LOCOMO Dataset](https://drive.google.com/drive/folders/1L-cTjTm0ohMsitsHg4dijSPJtqNflwX-?usp=drive_link)
The dataset contains conversational data specifically designed to test memory recall and understanding across various question types and complexity levels.
Place the dataset files in the `dataset/` directory:
- `locomo10.json`: Original dataset
- `locomo10_rag.json`: Dataset formatted for RAG experiments

## 🚀 Getting Started
### Prerequisites
Create a `.env` file with your API keys and configurations. The following keys are required:
```
# OpenAI API key for GPT models and embeddings
OPENAI_API_KEY="your-openai-api-key"
# Mem0 API keys (for Mem0 and Mem0+ techniques)
MEM0_API_KEY="your-mem0-api-key"
MEM0_PROJECT_ID="your-mem0-project-id"
MEM0_ORGANIZATION_ID="your-mem0-organization-id"
# Model configuration
MODEL="gpt-4o-mini" # or your preferred model
EMBEDDING_MODEL="text-embedding-3-small" # or your preferred embedding model
ZEP_API_KEY="api-key-from-zep"
```
### Running Experiments
You can run experiments using the provided Makefile commands:
#### Memory Techniques
```bash
# Run Mem0 experiments
make run-mem0-add # Add memories using Mem0
make run-mem0-search # Search memories using Mem0
# Run Mem0+ experiments (with graph-based search)
make run-mem0-plus-add # Add memories using Mem0+
make run-mem0-plus-search # Search memories using Mem0+
# Run RAG experiments
make run-rag # Run RAG with chunk size 500
make run-full-context # Run RAG with full context
# Run LangMem experiments
make run-langmem # Run LangMem
# Run Zep experiments
make run-zep-add # Add memories using Zep
make run-zep-search # Search memories using Zep
# Run OpenAI experiments
make run-openai # Run OpenAI experiments
```
Alternatively, you can run experiments directly with custom parameters:
```bash
python run_experiments.py --technique_type [mem0|rag|langmem] [additional parameters]
```
#### Command-line Parameters:
| Parameter | Description | Default |
|-----------|-------------|---------|
| `--technique_type` | Memory technique to use (mem0, rag, langmem) | mem0 |
| `--method` | Method to use (add, search) | add |
| `--chunk_size` | Chunk size for processing | 1000 |
| `--top_k` | Number of top memories to retrieve | 30 |
| `--filter_memories` | Whether to filter memories | False |
| `--is_graph` | Whether to use graph-based search | False |
| `--num_chunks` | Number of chunks to process for RAG | 1 |
### 📊 Evaluation
To evaluate results, run:
```bash
python evals.py --input_file [path_to_results] --output_file [output_path]
```
This script:
1. Processes each question-answer pair
2. Calculates BLEU and F1 scores automatically
3. Uses an LLM judge to evaluate answer correctness
4. Saves the combined results to the output file
### 📈 Generating Scores
Generate final scores with:
```bash
python generate_scores.py
```
This script:
1. Loads the evaluation metrics data
2. Calculates mean scores for each category (BLEU, F1, LLM)
3. Reports the number of questions per category
4. Calculates overall mean scores across all categories
Example output:
```
Mean Scores Per Category:
bleu_score f1_score llm_score count
category
1 0.xxxx 0.xxxx 0.xxxx xx
2 0.xxxx 0.xxxx 0.xxxx xx
3 0.xxxx 0.xxxx 0.xxxx xx
Overall Mean Scores:
bleu_score 0.xxxx
f1_score 0.xxxx
llm_score 0.xxxx
```
## 📏 Evaluation Metrics
We use several metrics to evaluate the performance of different memory techniques:
1. **BLEU Score**: Measures the similarity between the model's response and the ground truth
2. **F1 Score**: Measures the harmonic mean of precision and recall
3. **LLM Score**: A binary score (0 or 1) determined by an LLM judge evaluating the correctness of responses
4. **Token Consumption**: Number of tokens required to generate final answer.
5. **Latency**: Time required during search and to generate response.

Your task is to label an answer to a question as ’CORRECT’ or ’WRONG’. You will be given the following data:
(1) a question (posed by one user to another user),
(2) a ’gold’ (ground truth) answer,
(3) a generated answer
which you will score as CORRECT/WRONG.
The point of the question is to ask about something one user should know about the other user based on their prior conversations.
The gold answer will usually be a concise and short answer that includes the referenced topic, for example:
Question: Do you remember what I got the last time I went to Hawaii?
Gold answer: A shell necklace
The generated answer might be much longer, but you should be generous with your grading - as long as it touches on the same topic as the gold answer, it should be counted as CORRECT.
For time related questions, the gold answer will be a specific date, month, year, etc. The generated answer might be much longer or use relative time references (like "last Tuesday" or "next month"), but you should be generous with your grading - as long as it refers to the same date or time period as the gold answer, it should be counted as CORRECT. Even if the format differs (e.g., "May 7th" vs "7 May"), consider it CORRECT if it's the same date.
Now it's time for the real question:
Question: {question}
Gold answer: {gold_answer}
Generated answer: {generated_answer}
First, provide a short (one sentence) explanation of your reasoning, then finish with CORRECT or WRONG.
Do NOT include both CORRECT and WRONG in your response, or it will break the evaluation script.
Just return the label CORRECT or WRONG in a json format with the key as "label".

ANSWER_PROMPT_GRAPH = """
You are an intelligent memory assistant tasked with retrieving accurate information from
conversation memories.
# CONTEXT:
You have access to memories from two speakers in a conversation. These memories contain
timestamped information that may be relevant to answering the question. You also have
access to knowledge graph relations for each user, showing connections between entities,
concepts, and events relevant to that user.
# INSTRUCTIONS:
1. Carefully analyze all provided memories from both speakers
2. Pay special attention to the timestamps to determine the answer
3. If the question asks about a specific event or fact, look for direct evidence in the
memories
4. If the memories contain contradictory information, prioritize the most recent memory
5. If there is a question about time references (like "last year", "two months ago",
etc.), calculate the actual date based on the memory timestamp. For example, if a
memory from 4 May 2022 mentions "went to India last year," then the trip occurred
in 2021.
6. Always convert relative time references to specific dates, months, or years. For
example, convert "last year" to "2022" or "two months ago" to "March 2023" based
on the memory timestamp. Ignore the reference while answering the question.
7. Focus only on the content of the memories from both speakers. Do not confuse
character names mentioned in memories with the actual users who created those
memories.
8. The answer should be less than 5-6 words.
9. Use the knowledge graph relations to understand the user's knowledge network and
identify important relationships between entities in the user's world.
# APPROACH (Think step by step):
1. First, examine all memories that contain information related to the question
2. Examine the timestamps and content of these memories carefully
3. Look for explicit mentions of dates, times, locations, or events that answer the
question
4. If the answer requires calculation (e.g., converting relative time references),
show your work
5. Analyze the knowledge graph relations to understand the user's knowledge context
6. Formulate a precise, concise answer based solely on the evidence in the memories
7. Double-check that your answer directly addresses the question asked
8. Ensure your final answer is specific and avoids vague time references

ANSWER_PROMPT = """
You are an intelligent memory assistant tasked with retrieving accurate information from conversation memories.
# CONTEXT:
You have access to memories from two speakers in a conversation. These memories contain
timestamped information that may be relevant to answering the question.
# INSTRUCTIONS:
1. Carefully analyze all provided memories from both speakers
2. Pay special attention to the timestamps to determine the answer
3. If the question asks about a specific event or fact, look for direct evidence in the memories
4. If the memories contain contradictory information, prioritize the most recent memory
5. If there is a question about time references (like "last year", "two months ago", etc.),
calculate the actual date based on the memory timestamp. For example, if a memory from
4 May 2022 mentions "went to India last year," then the trip occurred in 2021.
6. Always convert relative time references to specific dates, months, or years. For example,
convert "last year" to "2022" or "two months ago" to "March 2023" based on the memory
timestamp. Ignore the reference while answering the question.
7. Focus only on the content of the memories from both speakers. Do not confuse character
names mentioned in memories with the actual users who created those memories.
8. The answer should be less than 5-6 words.
# APPROACH (Think step by step):
1. First, examine all memories that contain information related to the question
2. Examine the timestamps and content of these memories carefully
3. Look for explicit mentions of dates, times, locations, or events that answer the question
4. If the answer requires calculation (e.g., converting relative time references), show your work
5. Formulate a precise, concise answer based solely on the evidence in the memories
6. Double-check that your answer directly addresses the question asked
7. Ensure your final answer is specific and avoids vague time references

Generate personal memories that follow these guidelines:
1. Each memory should be self-contained with complete context, including:
- The person's name, do not use "user" while creating memories
- Personal details (career aspirations, hobbies, life circumstances)
- Emotional states and reactions
- Ongoing journeys or future plans
- Specific dates when events occurred
2. Include meaningful personal narratives focusing on:
- Identity and self-acceptance journeys
- Family planning and parenting
- Creative outlets and hobbies
- Mental health and self-care activities
- Career aspirations and education goals
- Important life events and milestones
3. Make each memory rich with specific details rather than general statements
- Include timeframes (exact dates when possible)
- Name specific activities (e.g., "charity race for mental health" rather than just "exercise")
- Include emotional context and personal growth elements
4. Extract memories only from user messages, not incorporating assistant responses
5. Format each memory as a paragraph with a clear narrative structure that captures the person's experience, challenges, and aspirations

# Changelog
All notable changes to the `@mem0/opencode-plugin` will be documented in this file.
## 0.2.0 — Native SDK tools, MCP-free, leaner skill set
### Changed (breaking)
- **Memory tools are now native OpenCode tools** registered via the `@opencode-ai/plugin` `tool()` helper and backed by the `mem0ai` SDK directly. The plugin no longer registers or depends on the remote MCP server (`mcp.mem0.ai`); the bundled `opencode.json` and the regex-based MCP call interception have been removed. Tools: `add_memory`, `search_memories`, `get_memories`, `get_memory`, `update_memory`, `delete_memory`, `delete_all_memories`, `delete_entities`, `list_entities`, plus a `get_event_status` helper for async-write status.
- **Skills load via the `config` hook (`skills.paths`)** instead of being copied into the project's `.opencode/` directory on startup. The `installSkills()` filesystem copy and the `cli.ts` installer (`mem0-opencode` bin) have been removed — install with `opencode plugin @mem0/opencode-plugin`.
- **Trimmed to 9 focused skills** (`context-loader`, `dream`, `forget`, `status`, `search`, `scope`, `pin`, `remember`, `tour`). Removed `import`, `export`, `memory-reviewer`, `mem0` (SDK reference), `list-projects`, `stats`, and `onboard`. The old stateful `switch-project` skill is superseded by the project/session/global scope model and the new `/mem0-scope` skill.
### Added
- **Expanded telemetry to the full shared `plugin.*` schema.** In addition to `plugin.session_start` and `plugin.tool_use`, the plugin now emits `plugin.user_prompt`, `plugin.bash_error`, `plugin.pre_compact`, and `plugin.session_stop`. `tool_use` now fires from inside each native tool. Every event also carries `project_hash` (anonymized `sha256(app_id)`) and `os_version`, matching the editor plugin's `telemetry.py`.
- **Auto-dream — gated automatic memory consolidation** (ported from the pi-agent plugin). When the time (`minHours`, default 24), session-count (`minSessions`, default 5), and memory-count (`minMemories`, default 20) gates all pass, the plugin injects a consolidation protocol so the agent merges duplicates, drops stale/sensitive entries, and rewrites vague ones before answering. A filesystem lock (`~/.mem0/mem0-dream.lock`) prevents concurrent sessions from dreaming at once, and completion resets the gates. Tune via the `dream` block in `~/.mem0/settings.json`; disable with `MEM0_DREAM=false`. Emits `plugin.dream_triggered` / `plugin.dream_completed`.
- **Memory `scope` — per-call parameter and a persistent default.** `search_memories`, `get_memories`, `add_memory`, and `delete_all_memories` accept an optional `scope`: `"project"` (this repo, default), `"session"` (this run, adds `run_id`), or `"global"` (across all the user's projects — `app_id: "*"` for reads, user-wide for writes). The new **`/mem0-scope` skill** views and changes the *default* scope (used when no scope is passed), persisted to `~/.mem0/settings.json` (`default_scope`) and read **fresh on each memory operation** so changes apply immediately — no restart. `add_memory` / `search_memories` / `get_memories` honor the default (an explicit `scope`, `filters`, or `agent_id` still wins; a `project` default preserves prior behavior, including `global_search`).
### Changed
- **`/mem0-status` now reports the active default scope and auto-dream readiness.** It reads `default_scope` from `~/.mem0/settings.json` (falling back to `project`) and shows the auto-dream gate progress (sessions / memories / time vs. thresholds) so it's clear *why* a consolidation hasn't run yet.
### Fixed
- **Skills load in place via `skills.paths` — no copying.** The `config` hook adds the plugin's own `opencode-skills/` directory to OpenCode's `skills.paths`, so OpenCode discovers the skills directly from the linked/installed plugin package (recursive `**/SKILL.md` scan). The `installSkills()` step that copied skills into `~/.config/opencode/skills/` (and the legacy `~/.opencode/skills/`) and its version-marker gating are removed — the plugin no longer writes into those directories or creates `~/.opencode`. The `config` hook still registers the `/mem0-*` slash commands via `config.command`: OpenCode's TUI slash menu is built from `config.command`, and skills on `skills.paths` are available to the agent's skill tool but do not appear as slash commands on their own. Skill dir names are `mem0-<skill>` (matching `^[a-z0-9]+(-[a-z0-9]+)*$`); commands are `/mem0-<skill>`.
- **Robust project-id (`app_id`) detection.** Parsed from the git remote's `owner/repo` — handling https, scp-style ssh, and **custom ssh host aliases** like `git@github.com-work:owner/repo.git` — falling back to the git repo's **root directory name** (not the cwd, which may be a sub-directory or your home dir), then the cwd. Fixes the project showing as your username/home when OpenCode was launched outside the repo root.
- **Auto-dream visibility + robustness.** When auto-dream doesn't fire, the plugin logs the blocking gate (e.g. `auto-dream waiting — memories: 3 < 20`), and `/mem0-status` surfaces the same gate progress. The session-start memory count is parsed defensively (handles both paginated `{count}` and bare-array SDK responses) so the memory gate evaluates correctly.
- **Error-pattern lookup** in `tool.execute.after` no longer issues two identical `mem0.search()` calls; it now performs a single `topK: 6` search.
- Corrected the documented system-prompt hook name from `experimental.chat.system.transform` to the actual `experimental.chat.messages.transform`.
### Safety
- **`delete_all_memories` deliberately ignores the default scope.** Deleting user-wide always requires an explicit `scope="global"`, so raising the default to `global` can never turn a routine cleanup into a cross-project wipe.
## 0.1.3 — File-context injection, session summaries & activity timeline, anonymous telemetry
### Added
- **File-context injection (`tool.execute.before` / Read):** Before the agent reads a file, the plugin searches mem0 for memories referencing that file path and injects prior work as system context. Gates on file size (>= 1,500 bytes). Gives the agent "I've worked on this file before" awareness automatically.
- **Stop hook session summary (`experimental.session.compacting`):** Enhanced session compaction to store a structured `session_summary` memory with `infer=True`, letting the mem0 backend AI extract key facts (request, decisions, learnings, next steps). Previously only stored a raw stats string.
- **SessionStart activity timeline:** The initial memory loading now formats recent memories with type icons (⚖️ decision, 🔴 bug_fix, 🔵 task_learning, etc.) and relative age indicators (2h ago, 1d ago) instead of bare text. Provides a visual "Recent Activity" timeline on first message.
- **PostHog telemetry (`telemetry.ts`):** Anonymous, fire-and-forget usage events. Opt out with `MEM0_TELEMETRY=false`. Only fires when an API key is present; never sends memory content, prompts, or the API key — only an anonymized `sha256(apiKey)[:32]` identity plus event type, platform, and plugin version. Emits the same schema as the Mem0 editor plugin (`plugin.*` events, `source: "plugin"`, `platform: "opencode"`) so OpenCode appears as a `platform` in the shared plugin dashboard. Events: `plugin.session_start` (with memory count) and `plugin.tool_use` (`add` / `search` / `update` / `delete`).
### Changed
- **`experimental.session.compacting` handler:** Now stores `metadata.type=session_summary` with `metadata.source=opencode-stop` instead of `metadata.type=session_state` with `metadata.source=pre-compaction`. Includes a structured prompt that instructs mem0's AI to extract request, decisions, learnings, and next steps.
- **Initial context formatting:** Memories shown on first message now include type icons and age labels for quick scanning.
## 0.1.2 — Automatic coding categories & global search
### Added
- **Auto-configured coding categories:** The plugin now automatically sets up 17 coding categories (e.g. `architecture_decisions`, `api_design`, `security`, `debugging_notes`) on the Mem0 project at startup. Runs in the background on every session start via `autoSetupCategories()`, is fully idempotent, and never blocks initialization. Uses SHA-256 fingerprints of the category list and API key — stored in `~/.mem0/categories_setup.json` — to skip redundant API calls on subsequent sessions.
- **Global search mode (`global_search` setting):** New `global_search` toggle in `~/.mem0/settings.json` (default: `false`). When enabled, all `search_memories` and `get_memories` calls use `{"OR": [{"user_id": "*"}]}` instead of the per-user per-project `AND` filter — returning all memories across all users and all `app_id` scopes. Writes (`add_memory`) still tag with the current `user_id` and `app_id`. Applies to all plugin search paths: initial load, per-message recall, resume detection, error-pattern lookup, and compaction context.
- **`/mem0:switch-project --global` / `--no-global`:** Enables or disables global search via the switch-project skill. Persists to `~/.mem0/settings.json`. No manual config editing needed.
- **`MEM0_GLOBAL_SEARCH` environment variable:** Exported to child shells via the `shell.env` hook (`"true"` or `"false"`).
### Changed
- **Search filters are now dynamic:** All search paths throughout the plugin construct filters based on the `global_search` setting instead of always using `AND [user_id, app_id]`.
- **Resume-context searches broadened:** Resume and error-pattern searches no longer include `metadata.type` sub-filters (`session_state`, `decision`, `anti_pattern`, `bug_fix`), broadening recall.
- **System context message updated:** Informs the model when global search is active (`"Global search is ON — searches return all memories across all users and projects. Writes still use user_id=..., app_id=..."`).
- **`/mem0:onboard` Step 5 is no longer interactive:** Removed the manual category installation prompt. Categories now configure automatically in the background; the onboarding step only verifies status and stores a fallback `project_profile` memory if the background run hasn't finished yet.
- **`/mem0:switch-project` skill expanded:** Description and execution updated to document the `--global` and `--no-global` flags alongside the existing project-name argument.
## 0.1.1
- CI/CD publish flow test (`#5288`).
- Fixed tsconfig, added `publishConfig` and bun lockfile (`#5273`).
- Renamed package to `@mem0/opencode-plugin` (`#5272`).
- Added plugin array to bundled `opencode.json` (`#5271`).
## 0.1.0 — Initial release
- **OpenCode plugin** (`@mem0/opencode-plugin` on npm): Pure TypeScript plugin using the `mem0ai` TS SDK — no Python, no shell scripts. Hooks into all 6 OpenCode events (`chat.message`, `tool.execute.before`, `tool.execute.after`, `experimental.chat.system.transform`, `experimental.session.compacting`, `shell.env`). Features: session start memory loading, per-prompt semantic search, error pattern detection with memory lookup, resume/remember intent detection, auto-capture every 3rd message, periodic save nudges, full metadata defaults injection (confidence, source, type, session_id, files, branch), identity injection for search/get/delete filters, type-filtered error pre-fetch (anti_pattern + bug_fix), pre-compaction memory capture, MEMORY.md write blocking, and secret redaction.
- **16 OpenCode-native skills** bundled in `opencode-skills/`: `context-loader`, `dream`, `export`, `forget`, `health`, `import`, `list-projects`, `mem0` (SDK reference), `memory-reviewer`, `onboard`, `peek`, `pin`, `remember`, `stats`, `switch-project`, `tour`. All skills are pure MCP-tool-based — no Python scripts, no shell scripts, no Claude Code dependencies.
- **Auto-install skills and commands (`installSkills()`):** On plugin load, copies all 16 skills to `.opencode/skills/` and creates command wrapper files in `.opencode/commands/` so they appear in the OpenCode `/` palette.
- **CLI installer (`cli.ts`):** `bunx @mem0/opencode-plugin install` auto-configures plugin and MCP server in `~/.config/opencode/opencode.json`.

# @mem0/opencode-plugin
Persistent memory for [OpenCode](https://opencode.ai). Your agent remembers decisions, preferences, and learnings across sessions automatically.
## Install
```bash
opencode plugin @mem0/opencode-plugin
```
This adds the plugin to your `~/.config/opencode/opencode.json`. The plugin registers its memory tools and skills itself — there is no MCP server to configure.
**Or let your agent do it** — paste this into OpenCode:
```
Install @mem0/opencode-plugin by following https://raw.githubusercontent.com/mem0ai/mem0/main/integrations/mem0-plugin/.opencode-plugin/README.md
```
Get your API key (free): [app.mem0.ai/dashboard/api-keys](https://app.mem0.ai/dashboard/api-keys)
```bash
echo 'export MEM0_API_KEY="m0-your-key"' >> ~/.zshrc && source ~/.zshrc
```
Restart OpenCode.
## What's included
| Component | Description |
|-----------|-------------|
| **9 Native Memory Tools** | `add_memory`, `search_memories`, `get_memories`, `update_memory`, `delete_memory`, and more — registered as OpenCode tools, backed by the `mem0ai` SDK (no MCP server required) |
| **Lifecycle Hooks** | Auto-search on session start and every prompt, error memory lookup, compaction context, secret redaction |
| **9 Skills** | `/mem0-remember`, `/mem0-tour`, `/mem0-search`, `/mem0-status`, `/mem0-scope`, `/mem0-dream`, `/mem0-forget`, `/mem0-pin`, `/mem0-context-loader` — discovered in place from the plugin via OpenCode's `skills.paths` |
## Hooks
Pure TypeScript — no Python, no shell scripts. Memory operations are native OpenCode tools backed by the [mem0ai](https://www.npmjs.com/package/mem0ai) SDK directly.
| Hook | Event | What it does |
|------|-------|-------------|
| **Config** | `config` | Registers the `/mem0-*` slash commands (via `config.command`) and adds the plugin's own `opencode-skills/` dir to OpenCode's `skills.paths` for in-place skill discovery — no copying into `~/.config/opencode/skills` |
| **Chat message** | `chat.message` | Loads prior memories on session start, searches relevant memories before each prompt, auto-captures learnings periodically |
| **Pre-tool** | `tool.execute.before` | Blocks MEMORY.md writes, steering them to the `add_memory` tool |
| **Post-tool** | `tool.execute.after` | Scans bash errors and pre-fetches related memories |
| **Messages transform** | `experimental.chat.messages.transform` | Injects memory context (session memories, search results, error lookups) into the prompt |
| **Compaction** | `experimental.session.compacting` | Stores session state memory, then injects prior memories into compaction context so nothing is lost |
| **Shell env** | `shell.env` | Exports `MEM0_USER_ID`, `MEM0_APP_ID`, `MEM0_SESSION_ID`, and `MEM0_BRANCH` to shell |
## Memory Tools
| Tool | Description |
|------|-------------|
| `add_memory` | Save text or conversation history |
| `search_memories` | Semantic search across memories |
| `get_memories` | List memories with filters and pagination |
| `get_memory` | Retrieve a specific memory by ID |
| `update_memory` | Overwrite a memory's text by ID |
| `delete_memory` | Delete a single memory by ID |
| `delete_all_memories` | Bulk delete all memories in scope |
| `delete_entities` | Delete an entity and its memories |
| `list_entities` | List users/agents/apps stored in Mem0 |
## Memory scope
Every memory tool accepts an optional `scope`, and you can set the **default**
scope (used when none is passed) with the `/mem0-scope` skill:
| Scope | Reads | Writes |
|-------|-------|--------|
| `project` (default) | this repo (`user_id` + `app_id`) | this repo |
| `session` | this run (adds `run_id`) | this run |
| `global` | all your projects (`app_id="*"`) | user-wide (drops `app_id`) |
```
/mem0-scope # show the current default scope
/mem0-scope global # save & search across all your projects by default
/mem0-scope project # back to repo-only (default)
```
The default persists in `~/.mem0/settings.json` (`default_scope`) and is read
fresh on each memory operation, so a change applies immediately — no restart.
`delete_all_memories` always requires an explicit `scope="global"` to delete
user-wide, so changing the default can't trigger a cross-project wipe.
## Verify
Start OpenCode and ask: *"Search my memories for recent decisions"*
If the `mem0` tools respond, you're all set.
## Troubleshooting
| Problem | Fix |
|---------|-----|
| No tools appearing | Restart OpenCode after installing |
| 401 Unauthorized | `echo $MEM0_API_KEY` must print your `m0-` key |
| Plugin not loading | Run `opencode plugin @mem0/opencode-plugin` again |

* sessions since) and the memory-count gate all pass, the plugin injects the
* DREAM_PROTOCOL into the agent's context so it consolidates memories (merge
* duplicates, drop stale/sensitive entries, rewrite vague ones) before
* answering. A filesystem lock prevents concurrent sessions from dreaming at
* once, and completion is recorded so it won't re-trigger until the next cycle.
*
* State + lock live in ~/.mem0/ alongside settings.json. Opt out with
* MEM0_DREAM=false, or tune via the `dream` block in ~/.mem0/settings.json.

You are running memory consolidation. Complete these steps using the mem0 memory tools (get_memories, add_memory, delete_memory):
1. ORIENT — Call get_memories to list all memories. Count by category. Note oldest/newest.
2. GATHER TARGETS — Review each memory. Classify as:
- DELETE: sensitive information (API keys, passwords, tokens), expired/stale entries, noise, redundant operational details
- MERGE: near-duplicates (same fact stated differently). Keep the better-worded one, delete the other.
- REWRITE: vague, first-person, or poorly-categorized entries. add_memory with improved text, then delete_memory the old one.
- KEEP: everything else.
Skip any memory starting with "[PINNED]".
3. CONSOLIDATE — Execute the changes:
- Delete stale/duplicate entries with delete_memory
- For merges: add_memory the merged text, delete_memory both originals
- For rewrites: add_memory the improved version, delete_memory the original
4. REPORT — Summarize: how many reviewed, deleted, merged, rewritten, final count.
Quality targets: zero sensitive data stored, zero duplicates, all entries are atomic (one fact each), 15-50 words each.
After consolidation, respond to the user's message normally.

name: mem0-scope
description: Views or changes the default memory scope (project, session, or global) used when saving and searching memories. Use when the user wants to control whether memories are scoped to this repo, this run, or shared across all their projects.
---
# Mem0 Scope
View or change the **default memory scope** — the scope the memory tools use when
no explicit `scope` is given. The setting persists in `~/.mem0/settings.json`
(`default_scope`) and the plugin reads it fresh on each memory operation, so a
change takes effect immediately in the current session.
The three scopes:
- `project` (default) — this repo only. Filters by `user_id` + `app_id`.
- `session` — this run only. Adds `run_id` (the current session) so memories are
isolated to this conversation.
- `global` — across ALL your projects. Reads use `app_id="*"`; writes drop
`app_id` so the memory is user-wide.
## Execution
### Step 1: Determine intent
Look at the user's message for a target scope word: `project`, `session`, or
`global` (also accept "repo"→project, "run"→session, "all"/"everywhere"→global).
- No target word present → **View mode** (Step 2).
- A target word present → **Change mode** (Step 3).
### Step 2: View mode — show the current scope
1. Read the current default scope from settings:
```bash
_S="$HOME/.mem0/settings.json"
[ -f "$_S" ] && grep -o '"default_scope"[[:space:]]*:[[:space:]]*"[a-z]*"' "$_S" | grep -o '[a-z]*"$' | tr -d '"' || echo "project"
```
If the command prints nothing, the scope is `project` (the default).
2. (Optional) Show how many memories live in the current scope by calling
`get_memories` with `scope="<current>"`, `page_size=1`, and reading the
`count` (or result length) from the response.
3. Display using the identity the plugin exported (do NOT re-shell git):
```
Mem0 memory scope
Current default scope: <current>
project - this repo only (user + app_id) <marker if active>
session - this run only (adds run_id) <marker if active>
global - all your projects (app_id = *) <marker if active>
User: ${MEM0_USER_ID}
Project: ${MEM0_APP_ID}
Session: ${MEM0_SESSION_ID}
To change: /mem0-scope session (or project / global)
```
Put `[active]` next to the current scope. If you fetched a count in step 2,
add a `Memories in scope: <N>` line.
### Step 3: Change mode — set a new scope
1. Validate the target is one of `project`, `session`, `global`. If not, show the
three options and stop.
2. Read the existing settings so you preserve every other key. Use the Read tool
on `~/.mem0/settings.json` (it may not exist yet — treat a missing file as
`{}`).
3. Write the file back with the Write tool, keeping ALL existing keys and only
setting `"default_scope"` to the target. Pretty-print with 2-space indent and
a trailing newline. Do not drop `global_search`, `dream`, `auto_save`, or any
other field that was present.
Example resulting file (when other keys already existed):
```json
{
"auto_save": true,
"search_limit": 10,
"default_scope": "global"
}
```
4. Confirm:
```
Default memory scope changed: <old> -> <new>
<one line describing the effect — see below>
Applies immediately to memory tools in this session.
To revert: /mem0-scope <old>
```
Effect lines:
- project → "New memories and searches are limited to this repo."
- session → "New memories and searches are limited to this run (this conversation)."
- global → "New memories and searches span all your projects. delete_all_memories still needs an explicit scope=global to delete user-wide."
### Notes
- This only changes the **default**. Any memory tool call can still pass an
explicit `scope` to override it for that one call.
- `delete_all_memories` deliberately ignores the default scope: deleting
user-wide always requires an explicit `scope="global"`, so changing the
default can never turn a routine cleanup into a cross-project wipe.
- `global` scope (this user, all their projects) is distinct from the separate
`global_search` setting (all users). Leave `global_search` untouched here.

Resolve identity from environment variables set by the plugin's `shell.env` hook:
Resolve identity from the `MEM0_*` environment variables set by the plugin's `shell.env` hook. These are the exact values the plugin uses to scope memories, so report them directly. Do NOT re-run `git` here: the plugin already resolved branch and project from git at session start, and re-shelling git can disagree with it — e.g. it prints an empty branch that renders as `(not a git repo)` while the Session check below shows `branch=main`. One source of truth keeps the two lines consistent.
```bash
echo "user_id=${MEM0_USER_ID:-${USER:-}}"
echo "user_id=${MEM0_USER_ID:-${USER:-default}}"
echo "project_id=${MEM0_APP_ID:-}"
echo "branch=$(git branch --show-current 2>/dev/null || echo '')"

```

- `project_id`: from `MEM0_APP_ID`
- `branch`: from `git branch --show-current`

### Check 6: Auto-dream readiness
Explain whether auto-dream (memory consolidation) is eligible to run, and if not, exactly which gate is blocking. Auto-dream runs at most once per session and only when **all** gates pass: time since last consolidation ≥ `minHours`, sessions since ≥ `minSessions`, and project memory count ≥ `minMemories`.
Read the gate state and thresholds:
```bash
_ST="$HOME/.mem0/mem0-dream-state.json"
_SET="$HOME/.mem0/settings.json"
echo "sessions_since=$(grep -o '"sessionsSince"[[:space:]]*:[[:space:]]*[0-9]*' "$_ST" 2>/dev/null | grep -o '[0-9]*$' || echo 0)"
echo "last_consolidated_ms=$(grep -o '"lastConsolidatedAt"[[:space:]]*:[[:space:]]*[0-9]*' "$_ST" 2>/dev/null | grep -o '[0-9]*$' || echo 0)"
echo "min_hours=$(grep -o '"minHours"[[:space:]]*:[[:space:]]*[0-9]*' "$_SET" 2>/dev/null | grep -o '[0-9]*$' || echo 24)"
echo "min_sessions=$(grep -o '"minSessions"[[:space:]]*:[[:space:]]*[0-9]*' "$_SET" 2>/dev/null | grep -o '[0-9]*$' || echo 5)"
echo "min_memories=$(grep -o '"minMemories"[[:space:]]*:[[:space:]]*[0-9]*' "$_SET" 2>/dev/null | grep -o '[0-9]*$' || echo 20)"
echo "now_s=$(date +%s)"
echo "dream_env=${MEM0_DREAM:-unset}"
```
For the memory count, reuse the project memory count from Check 3/4 (or call `get_memories` with the project filter, `page_size=1`, and read `count`).
Compute each gate:
- **time**: `hours_since = (now_s - last_consolidated_ms/1000) / 3600`. Passes when `≥ min_hours`. If `last_consolidated_ms` is 0 it has never run → time gate passes.
- **sessions**: passes when `sessions_since ≥ min_sessions`.
- **memories**: passes when project memory count `≥ min_memories`.
Report:
- If `dream_env` is `false`/`0`/`no`/`off`, or `dream.enabled` is false in settings: WARN — "Auto-dream disabled".
- If all three gates pass: PASS — "eligible (runs at next session start)".
- Otherwise: WARN — list the blocking gate(s), e.g. `sessions 2/5, memories 3/20`. This is expected, not an error — auto-dream is just waiting. Note the user can run `/mem0-dream` to consolidate now, or lower the thresholds via the `dream` block in `~/.mem0/settings.json`.

All notable changes to the Mem0 plugin will be documented in this file.
## 0.2.10 — Accurate per-editor telemetry attribution
### Fixed
- **Antigravity counted as Claude Code:** `detect_platform()` (`scripts/telemetry.py`) now checks `ANTIGRAVITY_PLUGIN_ROOT` before the `CLAUDE_PLUGIN_ROOT` branch. Antigravity sets both env vars for compatibility, so every Antigravity session was previously attributed to `claude-code`. Telemetry now reports `platform: "antigravity"`.
- **Codex fell back to the generic `plugin` bucket:** Codex installs standalone hooks with absolute paths via `install_codex_hooks.py`, so `PLUGIN_ROOT` is never set at runtime and platform auto-detection failed. Each command in `hooks/codex-hooks.json` now pins `MEM0_PLATFORM=codex` inline (Codex runs hook commands through a shell). Telemetry now reports `platform: "codex"`.
- **Cursor attribution depended on the host env:** Cursor's `*_cursor.sh` wrappers delegate to the shared hook scripts, whose platform detection relied on Cursor exporting `CURSOR_PLUGIN_ROOT` to the subprocess. All five Cursor wrappers now `export MEM0_PLATFORM=cursor` before delegating.
- **`plugin_version` was identical for every editor:** telemetry read `.claude-plugin/plugin.json` for all bash-hook editors, so Antigravity reported `0.2.10` instead of its real `0.1.2`. `_load_plugin_version()` now reads the manifest matching the detected platform, so each editor reports its own version.
### Added
- **`MEM0_PLATFORM` override in `detect_platform()`:** An explicit platform marker that wins over env-var auto-detection, letting each editor label its telemetry reliably. New tests in `tests/test_telemetry.py` cover the override, Antigravity attribution, and the Cursor/Codex platform-pinning contracts.
> Attribution fixes apply to telemetry emitted after users upgrade to this version; PostHog does not backfill past events.
## 0.2.9 — File-context injection, session summaries & activity timeline
