## When to Use

✅ **USE when:**
- An agent needs to "remember" information from previous sessions
- You want to give additional context to an LLM about past actions
- You need semantic search by content
- You want to store important decisions with metadata

❌ **DON'T USE when:**
- Ephemeral information that doesn't need persistence
- Structured tabular data (use a regular DB)
- Simple cache (use Redis or in-memory)

## Auto-Injection (Hook)

BrainX V5 includes an **OpenClaw hook** that automatically injects relevant memories when an agent starts.

### Production Validation Status

Real validation completed on **2026-03-18**:
- Global hook enabled in `~/.openclaw/openclaw.json`
- Managed hook synced with `~/.openclaw/skills/brainx-v5/hook/` (handler.js re-synced)
- Active physical database: `brainx_v5`
- agent-profiles.json expanded from 10 to 32 profiles (all agents)
- Cross-agent injection slots (30%) activated in production
- 20 null embeddings regenerated + 17 duplicate pairs deduped via `brainx fix`
- 2 pending migrations applied
- Doctor: 18/18 passed, 0 warnings
- Real bootstrap smoke test passed for 10 agents
- Expected evidence confirmed:
  - `<!-- BRAINX:START -->` block written into `MEMORY.md`
  - `Updated:` timestamp present
  - Fresh row recorded in `brainx_pilot_log`

If this validation becomes stale, rerun a bootstrap smoke test before assuming runtime is still healthy.

### How it works:

1. `agent:bootstrap` event → Hook fires automatically
2. PostgreSQL query → Fetches hot/warm recent memories
3. Generates file → Creates `BRAINX_CONTEXT.md` in the workspace
4. Agent reads → File is loaded as initial context

### Configuration:

In `~/.openclaw/openclaw.json`:
```json
{
  "hooks": {
    "internal": {
      "enabled": true,
      "entries": {
        "brainx-auto-inject": {
          "enabled": true,
          "limit": 5,
          "tier": "hot+warm",
          "minImportance": 5
        }
      }
    }
  }
}
```

### Per-agent setup:

Add to `AGENTS.md` in each workspace:
```markdown
## Every Session

1. Read `SOUL.md`
2. Read `USER.md`
3. Read `brainx.md`
4. Read `BRAINX_CONTEXT.md` ← Auto-injected context
```

## Backup and Recovery

### Create Backup

```bash
./scripts/backup-brainx.sh ~/backups
```

Creates `brainx-v5_backup_YYYYMMDD_HHMMSS.tar.gz` containing:
- Full PostgreSQL database (SQL dump)
- OpenClaw configuration (hooks, .env)
- Skill files
- Workspace documentation

### Restore Backup

```bash
./scripts/restore-brainx.sh backup.tar.gz --force
```

Fully restores BrainX V5 including:
- All memories (with embeddings)
- Hook configuration
- Environment variables

### Full Documentation

See [RESILIENCE.md](RESILIENCE.md) for:
- Complete disaster scenarios
- Migration to new VPS
- Troubleshooting
- Automatic backup configuration

## Configuration

### Environment Variables

```bash
# Required
DATABASE_URL=postgresql://user:pass@host:5432/brainx_v5
OPENAI_API_KEY=sk-...

# Optional
OPENAI_EMBEDDING_MODEL=text-embedding-3-small
OPENAI_EMBEDDING_DIMENSIONS=1536
BRAINX_INJECT_DEFAULT_TIER=hot+warm
BRAINX_INJECT_MAX_CHARS_PER_ITEM=2000
BRAINX_INJECT_MAX_LINES_PER_ITEM=80
```

### Database Setup

```bash
# Schema is in ~/.openclaw/skills/brainx-v5/sql/
# Requires PostgreSQL with pgvector extension

psql $DATABASE_URL -f ~/.openclaw/skills/brainx-v5/sql/v3-schema.sql
```

## Direct Integration

You can also use the unified wrapper that reads the API key from OpenClaw:

```bash
cd ~/.openclaw/skills/brainx-v5
./brainx add --type note --content "test"
./brainx search --query "test"
./brainx inject --query "test"
./brainx health
```

Compatibility: `./brainx-v5` and `./brainx-v5-cli` also work as aliases for the main wrapper.

## Advisory System (Pre-Action Check)

BrainX includes an advisory system that queries relevant memories, trajectories, and recurring patterns before executing high-risk tools. Helps agents avoid repeating past mistakes.

### High-Risk Tools

The following tools automatically trigger advisory checks: `exec`, `deploy`, `railway`, `delete`, `rm`, `drop`, `git push`, `git force-push`, `migration`, `cron`, `message send`, `email send`.

### CLI Usage

```bash
# Check for advisories before a tool execution
./brainx-v5 advisory --tool exec --args '{"command":"rm -rf /tmp/old"}' --agent coder --json

# Quick check via helper script
./scripts/advisory-check.sh exec '{"command":"rm -rf /tmp/old"}' coder
```

### Agent Integration (Manual)

Since only `agent:bootstrap` is supported as a hook event, agents should manually call `brainx advisory` before high-risk tools:

```bash
# In agent SKILL.md or AGENTS.md, add:
# Before exec/deploy/delete/migration, run:
cd ~/.openclaw/skills/brainx-v5 && ./scripts/advisory-check.sh <tool> '<args_json>' <agent>
```

The advisory returns relevant memories, similar past problem→solution paths, and recurring patterns with a confidence score. It's informational — never blocking.

### Agent-Aware Hook Injection

The `agent:bootstrap` hook uses **agent profiles** (`hook/agent-profiles.json`) to customize memory injection per agent:

- **coder**: Boosts gotcha/error/learning memories; filters by infrastructure/code/deploy/github contexts; excludes notes
- **writer**: Boosts decision/learning; filters by content/seo/marketing; excludes errors
- **monitor**: Boosts gotcha/error; filters by infrastructure/health/monitoring
- **echo**: No filtering (default behavior)

Agents not listed in the profiles file get the default unfiltered injection. Edit `hook/agent-profiles.json` to add new agent profiles.

### Cross-Agent Memory Sharing

The hook reserves ~30% of injection slots for **cross-agent memories**, ensuring each agent sees relevant learnings from other agents. The `cross-agent-learning.js` script tags high-importance memories for cross-agent visibility without creating duplicates.

## Security & Trust

This skill is flagged with "suspicious patterns" by ClawHub's automated scanner. Here's what each pattern does and why it's necessary:

| Pattern | File | Why |
|---|---|---|
| `child_process.execFile` | `hook/handler.js` | Invokes the BrainX CLI to query memories during agent bootstrap. No arbitrary command execution. |
| `process.env` access | `lib/db.js`, `lib/openai-rag.js`, `lib/cli.js` | Reads `DATABASE_URL` and `OPENAI_API_KEY` to connect to PostgreSQL and generate embeddings. Standard for any database-backed skill. |
| `fetch('https://api.openai.com')` | `lib/openai-rag.js` | Calls OpenAI Embeddings API to generate vector representations. Single endpoint, no other network calls. |
| File read/write | `hook/handler.js` | Writes `BRAINX_CONTEXT.md` and updates `MEMORY.md` in the agent's workspace during bootstrap injection. |

**No secrets are stored in code.** All credentials come from environment variables. No data leaves the system except embedding requests to OpenAI.

## Notes

- Memories are stored with vector embeddings (1536 dimensions)
- Search uses cosine similarity
- `inject` is the most useful tool for giving context to LLMs
- Tier hot = fast access, cold/archive = long-term storage
- Memories are persistent in PostgreSQL (independent of OpenClaw)
- Auto-injection hook fires on every `agent:bootstrap`
