description

Use when an agent must stand up the OpenClaw↔Cognee integration with FalkorDB as the vector + graph store. This skill is SELF-CONTAINED — it tells you to generate every file (Dockerfile, sitecustomize.py, docker-compose.yaml) from the exact contents below, build a custom Cognee image that loads the FalkorDB adapter, run Cognee + FalkorDB together, self-verify the adapter registered, and point the OpenClaw cognee plugin at it (including per-agent graphs). No other files in this directory are required.

Cognee + FalkorDB setup for OpenClaw (self-contained)

You (the agent) will generate the files below, build a custom Cognee image, run it alongside FalkorDB, verify the FalkorDB adapter is active, then configure the OpenClaw cognee-openclaw plugin. Follow the steps in order. Each major step has a verify check — if a check fails, follow its "if it fails" note before continuing. Do not skip verification.

Preconditions (fail loudly if unmet)

• You can write files in a working directory and run Docker (docker, docker compose).
• You have an LLM API key (OpenAI by default) for Cognee's entity extraction.
• Pick a working directory, e.g. the directory containing this skill. All paths below are relative to it.

If you cannot write files or run Docker, stop and report that — this skill cannot proceed.

Why this construction (read once)

The stock cognee/cognee image does not ship the FalkorDB adapter, and there is no env var that turns it on. Cognee's falkor provider only becomes resolvable after cognee_community_hybrid_adapter_falkor.register is imported — that import registers the falkor graph + vector providers and the falkor_graph_local / falkor_vector_local per-dataset handlers. So we:

1. install the adapter into Cognee's venv, and
2. drop a sitecustomize.py on the image's PYTHONPATH (/app). Python auto-imports sitecustomize at interpreter startup for every process — the gunicorn master, each worker, and the alembic migration — so register runs before any DB engine is created, without editing Cognee's entrypoint.

This is deliberately the smallest possible change (no custom entrypoint, no app wrapper) so it stays correct across Cognee patch releases.

Step 1 — Generate the files

Create these three files verbatim in your working directory.

sitecustomize.py

# Auto-imported by Python on startup because it sits on PYTHONPATH=/app in the
# cognee image. Importing the adapter's `register` module here makes the
# "falkor" graph + vector providers and the falkor_*_local per-dataset handlers
# resolvable BEFORE Cognee creates any engine — no entrypoint/app edits needed.
import cognee_community_hybrid_adapter_falkor.register  # noqa: F401

Dockerfile

# Custom Cognee image with the FalkorDB hybrid adapter registered.
# Keeps the stock entrypoint and stock app (cognee.api.client:app); the adapter
# is activated by sitecustomize.py (auto-imported via PYTHONPATH=/app).
FROM cognee/cognee:1.1.0

# uv installs into the uv-created venv (which has no pip). --no-deps on the
# adapter avoids re-resolving the already-installed cognee; its other deps
# (starlette, instructor) are already present. Install the falkordb client too.
COPY --from=ghcr.io/astral-sh/uv:latest /uv /usr/local/bin/uv
RUN uv pip install --python /app/.venv/bin/python --no-deps "cognee-community-hybrid-adapter-falkor==0.3.0" \
 && uv pip install --python /app/.venv/bin/python "falkordb>=1.0.9,<2.0.0"

# Auto-imported on every interpreter start -> registers the FalkorDB adapter.
COPY sitecustomize.py /app/sitecustomize.py

# Use FalkorDB for BOTH vector and graph, with per-dataset isolation (each
# dataset -> its own FalkorDB graph keyed by dataset_id) and multi-user access
# control. URLs point at the "falkordb" compose service; override via env if you
# rename it or run Cognee outside compose.
ENV GRAPH_DATABASE_PROVIDER=falkor \
    GRAPH_DATABASE_URL=falkordb \
    GRAPH_DATABASE_PORT=6379 \
    VECTOR_DB_PROVIDER=falkor \
    VECTOR_DB_URL=falkordb \
    VECTOR_DB_PORT=6379 \
    GRAPH_DATASET_DATABASE_HANDLER=falkor_graph_local \
    VECTOR_DATASET_DATABASE_HANDLER=falkor_vector_local \
    ENABLE_BACKEND_ACCESS_CONTROL=True

Version pins: cognee/cognee:1.1.0 matches this repo. The adapter is pinned to 0.3.0; the adapter supports cognee >=1.0.3,<2.0.0. If the build fails on the adapter install, check the latest compatible version on PyPI (cognee-community-hybrid-adapter-falkor) and update the pin — do not drop the pin entirely.

docker-compose.yaml

services:
  falkordb:
    image: falkordb/falkordb:latest
    container_name: falkordb
    ports:
      - "127.0.0.1:6379:6379"   # FalkorDB/Redis protocol
      - "127.0.0.1:3001:3000"   # FalkorDB browser UI (optional)
    volumes:
      - falkordb_data:/data
    restart: unless-stopped
    healthcheck:
      test: [ "CMD", "redis-cli", "ping" ]
      interval: 10s
      timeout: 5s
      retries: 5

  cognee:
    build:
      context: ..
      dockerfile: Dockerfile
    image: cognee-falkor:1.1.0
    container_name: cognee
    depends_on:
      falkordb:
        condition: service_healthy
    ports:
      - "127.0.0.1:8000:8000"
    environment:
      - LLM_API_KEY=${LLM_API_KEY}
      - AUTO_FEEDBACK=true
    volumes:
      - 
     
    
       [ , , ,  ]
       
       
       
       


  
  

Verify (files): ls sitecustomize.py Dockerfile docker-compose.yaml lists all three.

Step 2 — Build and run

export LLM_API_KEY="sk-..."          # required; or put LLM_API_KEY=... in a .env file here
docker compose up -d --build

Verify (build & containers):

docker compose ps          # both 'falkordb' and 'cognee' present

If the build failed on the adapter install: re-read the Dockerfile version pin note above, adjust the adapter version, and rerun docker compose up -d --build.

Step 3 — Verify the FalkorDB adapter actually registered (critical)

This is the check that distinguishes a working Falkor backend from a silently broken one. Wait for health, then confirm the providers resolve inside the container:

# 1. API healthy (retry for ~60s on first boot while migrations run)
until curl -fsS http://localhost:8000/health >/dev/null; do sleep 3; done; echo "health OK"

# 2. The 'falkor' providers + per-dataset handlers are registered
docker exec cognee /app/.venv/bin/python -c "import sitecustomize; \
from cognee.infrastructure.databases.graph.supported_databases import supported_databases as g; \
from cognee.infrastructure.databases.vector.supported_databases import supported_databases as v; \
from cognee.infrastructure.databases.dataset_database_handler.supported_dataset_database_handlers import supported_dataset_database_handlers as h; \
print('graph falkor:', 'falkor' in g); print('vector falkor:', 'falkor' in v); \
print('handlers:', [k for k in h if 'falkor' in k])"

# 3. FalkorDB reachable
docker exec falkordb redis-cli PING        # -> PONG

Expected: graph falkor: True, vector falkor: True, handlers: ['falkor_graph_local', 'falkor_vector_local'], and PONG.

If graph falkor: False: the adapter didn't register. Confirm docker exec cognee ls /app/sitecustomize.py exists and that the uv pip install of cognee-community-hybrid-adapter-falkor succeeded in the build logs (docker compose build cognee and read the output). Fix and rebuild. Do not proceed until this prints True.

Step 4 — Point the OpenClaw plugin at this Cognee

The cognee-openclaw plugin is backend-agnostic — it only needs the API URL. In ~/.openclaw/openclaw.json:

{
  plugins: {
    slots: { memory: "cognee-openclaw" },
    entries: {
      "cognee-openclaw": {
        enabled: true,
        hooks: { allowConversationAccess: true },
        config: {
          baseUrl: "http://localhost:8000",
          // For multiple agents: give each its own graph.
          agentDatasetPrefix: "openclaw-cognee-agent",
          recallScopes: ["agent"],
          defaultWriteScope: "agent"
        }
      }
    }
  }
}

Per-agent graphs: when the gateway hosts more than one agent (agents.list.length > 1), the plugin auto-enables per-agent memory — each agent's files + chat route to {agentDatasetPrefix}-{agentId} (agentId lowercased), i.e. its own FalkorDB graph. Give each agent its own workspace in agents.list and seed a one-line MEMORY.md in each so its dataset is created on gateway start. Force the mode with perAgentMemory: true|false if needed.

Step 5 — Verify end-to-end

openclaw gateway stop && openclaw gateway start

# Datasets show up in Cognee as agents become active:
TOKEN=$(curl -s -X POST http://localhost:8000/api/v1/auth/login \
  -H "Content-Type: application/x-www-form-urlencoded" \
  --data-urlencode username=[e-mail] \
  --data-urlencode password=default_password \
  | python3 -c "import sys,json;print(json.load(sys.stdin)['access_token'])")
curl -s http://localhost:8000/api/v1/datasets -H "Authorization: Bearer $TOKEN"

# One FalkorDB graph per dataset_id:
docker exec falkordb redis-cli GRAPH.LIST

Chat-derived memory only lands in the graph after the session-cache → /improve bridge runs (on session_end, or force it with openclaw cognee improve --dataset <name>). For a quick multi-agent isolation check: tell agent A something, end its session, ask agent B — B should not know it.

Operations & cleanup

docker compose logs -f cognee      # follow Cognee logs
docker compose restart cognee      # after env changes
docker compose down                # stop, keep data
docker compose down -v             # stop AND wipe Cognee + FalkorDB data

Wipe Cognee data via API (keeps containers), then clear the plugin's local state:

openclaw cognee forget --everything --confirm
rm -f ~/.openclaw/memory/cognee/*.json

Gotchas (each has bitten a real setup)

• Stock image won't work via env vars alone. Without sitecustomize.py importing register, *_PROVIDER=falkor fails at engine creation. The Step 3 check catches this.
• Adapter version drift. Keep the Dockerfile pin; bump it deliberately if PyPI breaks against the cognee base tag.
• Base-image tag. Bump cognee/cognee:1.1.0 and the adapter pin together if you move Cognee versions.
• GRAPH_DATABASE_URL must resolve to the FalkorDB host — under this compose it's the service name falkordb.
• Stale plugin state. If datasets look empty or chat lands in the wrong graph after recreating the server, rm -f ~/.openclaw/memory/cognee/*.json and restart the gateway so it rebuilds against the fresh server.
• Stable credentials. If you set apiKey/username on the plugin, keep them constant — dataset ownership is per-user; switching identities orphans existing datasets.
