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:

{
  "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:

## Every Session

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

Configuration

Environment Variables

# 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

# 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:

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

# 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:

# 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
