Supermemory Free — Cloud Knowledge Backup

Backs up important knowledge and insights to Supermemory.ai's cloud using the free tier API.
Uses only /v3/documents (store) and /v3/search (retrieve) — no Pro-only endpoints.

Prerequisites

Set in .env

SUPERMEMORY_OPENCLAW_API_KEY="sm_..."

Tools

supermemory_cloud_store

Store a knowledge string to the cloud.

python3 skills/supermemory-free/store.py "Your knowledge string here"

# With optional container tag (namespace/filter)
python3 skills/supermemory-free/store.py "knowledge string" --tag openclaw

# With metadata
python3 skills/supermemory-free/store.py "knowledge string" --tag fixes --source "session"

# Output raw JSON
python3 skills/supermemory-free/store.py "knowledge string" --json

When to use: - User asks to "remember" something permanently - Important configuration/setup knowledge - Resolved problems / solutions discovered - Key facts you want cross-session persistence for

supermemory_cloud_search

Search the cloud memory for relevant knowledge.

python3 skills/supermemory-free/search.py "your query"

# With container tag filter
python3 skills/supermemory-free/search.py "your query" --tag openclaw

# More results
python3 skills/supermemory-free/search.py "your query" --limit 10

# Higher precision (less noise)
python3 skills/supermemory-free/search.py "your query" --threshold 0.7

# Search across ALL tags
python3 skills/supermemory-free/search.py "your query" --no-tag

When to use: - Local memory (MEMORY.md, daily logs) doesn't have the answer - User references something from "a long time ago" - Cross-session knowledge lookup - "Do you remember when..." queries

Auto-Capture (Cron)

Scans recent session memory logs and automatically pushes high-value insights to Supermemory cloud.

# Run manually
python3 skills/supermemory-free/auto_capture.py

# Dry run (show what would be captured, no upload)
python3 skills/supermemory-free/auto_capture.py --dry-run

# Scan last N days (default: 3)
python3 skills/supermemory-free/auto_capture.py --days 7

# Force re-upload even if already seen
python3 skills/supermemory-free/auto_capture.py --force

# Verbose mode
python3 skills/supermemory-free/auto_capture.py --verbose

Install cron job (runs daily at 2:00 AM UTC):

bash skills/supermemory-free/install_cron.sh

Remove cron job:

bash skills/supermemory-free/install_cron.sh --remove

Check cron status:

bash skills/supermemory-free/install_cron.sh --status

What Gets Auto-Captured

The auto-capture script identifies "high-value" insights from memory logs using these heuristics:

Pattern	Label	Example
Resolved errors / fixes	`fix`	`Fixed: SSL cert error by running...`
Error context	`error`	`Exception: Connection refused on port 5432`
Configuration paths	`config`	`/etc/nginx/sites-available/default`
API/endpoint info	`api`	`Endpoint: POST /v3/documents for storage`
User preferences	`preference`	`User prefers Python over Node for scripts`
Decisions made	`decision`	`Decided to use PostgreSQL because...`
Learned facts	`insight`	`Learned that cron syntax for...`
Installs / setup	`setup`	`Installed nginx, configured with...`
Bullet-point blocks	`bullet`	`- Key finding: X works better than Y`

Deduplication: Already-uploaded items are tracked in .capture_state.json — re-running is safe.

Container Tags

Use --tag to namespace your memories:

Tag	Purpose
`openclaw`	General OpenClaw session knowledge (default)
`fixes`	Bug fixes and solutions
`config`	Configuration and setup
`user-prefs`	User preferences
`projects`	Project-specific knowledge

Files

File	Purpose
`store.py`	CLI tool: upload knowledge to cloud
`search.py`	CLI tool: search cloud knowledge
`auto_capture.py`	Cron script: auto-analyze memory logs
`install_cron.sh`	Install/remove/status of cron job
`.capture_state.json`	Dedup state (auto-generated, gitignore)
`SKILL.md`	This file
`_meta.json`	Skill metadata

API Info

Base URL: https://api.supermemory.ai
Store endpoint: POST /v3/documents
Search endpoint: POST /v3/search
Auth: Bearer token from SUPERMEMORY_OPENCLAW_API_KEY
Free tier limits: Check https://console.supermemory.ai for current quotas
Note: Cloudflare-compatible headers included — avoids 1010 access denial errors

Troubleshooting

HTTP 403 / 1010 Access Denied:
The scripts include proper User-Agent, Origin, and Referer headers to satisfy Cloudflare. If it recurs, verify the API key is valid at https://console.supermemory.ai.

No memory files found:
Auto-capture looks in memory/YYYY-MM-DD.md. Ensure your memory skill is writing daily logs there.

Re-upload everything:
Delete .capture_state.json or use --force to ignore the dedup state.
