# Cloud Sync (cmem.ai Pro)
The installed worker syncs through SyncHub. There is one client, one durable
operation log, and no separate sync daemon. This skill checks status or writes
the three connection values issued by **cmem.ai → Connect**.
**Security rule:** never print the sync token, put it in argv, or log it.
Confirm only its length. Preserve every unrelated setting and keep
`~/.claude-mem/settings.json` mode `0600`.
## 1. Check status
Resolve the worker port and query the always-registered status route:
```bash
PORT="${CLAUDE_MEM_WORKER_PORT:-$(node -e "const fs=require('fs'),p=require('path'),os=require('os');const uid=(typeof process.getuid==='function'?process.getuid():77);const fallback=String(37700+(uid%100));try{const s=JSON.parse(fs.readFileSync(p.join(os.homedir(),'.claude-mem','settings.json'),'utf-8'));process.stdout.write(String(s.CLAUDE_MEM_WORKER_PORT||fallback));}catch{process.stdout.write(fallback);}" 2>/dev/null)}"
curl -s "http://127.0.0.1:${PORT}/api/sync/status"
```
- `configured: true` and `hub.reachable: true` → the worker completed an
authenticated `GET /v1/sync/status` against SyncHub. Report `deviceId`,
pending counts, `lastFlushAt`, `lastError`, and the Hub head/checkpoint;
stop unless the user asked to replace the connection.
- `configured: true` and `hub.reachable: false` → report `hub.error` and say
the SyncHub connection is not verified. A zero pending count or
`lastError: null` is not success because an empty queue performs no push.
- `configured: false` → continue.
- Connection refused, 404, or 503 immediately after restart → retry every
three seconds for about 30 seconds before diagnosing the worker.
## 2. Obtain the connection
Ask for all three values shown by **cmem.ai → Connect**:
1. sync token;
2. user id;
3. SyncHub URL.
The Hub URL must be an absolute `https://` URL. Do not substitute the cmem.ai
application API URL; the installed client talks only to SyncHub.
## 3. Write installed-client settings
Substitute the collected values inside this quoted stdin script. Do not echo
them before or after running it:
```bash
node - <<'EOF'
const fs = require('fs'), os = require('os'), path = require('path');
const token = 'PASTE_TOKEN_HERE';
const userId = 'PASTE_USER_ID_HERE';
const hubUrl = 'PASTE_HUB_URL_HERE';
if (!token || !userId || !/^https:\/\/[^\s]+$/.test(hubUrl)) {
console.error('token, user id, and an https SyncHub URL are required');
process.exit(1);
}
const dir = path.join(os.homedir(), '.claude-mem');
const file = path.join(dir, 'settings.json');
fs.mkdirSync(dir, { recursive: true });
const settings = fs.existsSync(file) ? JSON.parse(fs.readFileSync(file, 'utf8')) : {};
const target = settings.env && typeof settings.env === 'object' ? settings.env : settings;
target.CLAUDE_MEM_CLOUD_SYNC_TOKEN = token;
target.CLAUDE_MEM_CLOUD_SYNC_USER_ID = userId;
target.CLAUDE_MEM_CLOUD_SYNC_HUB_URL = hubUrl.replace(/\/+$/, '');
fs.writeFileSync(file, JSON.stringify(settings, null, 2) + '\n', { mode: 0o600 });
fs.chmodSync(file, 0o600);
console.log(`saved cloud connection: token length ${token.length}, user id length ${userId.length}`);
EOF
```
These are the only required connection keys. The worker mints and persists a
device id on first start and defaults the device name to the hostname.
## 4. Restart and verify
```bash
curl -s -X POST "http://127.0.0.1:${PORT}/api/admin/restart"
```
Poll the status route every five seconds for up to 30 seconds while the
successor starts. Success means `configured: true`, `hub.reachable: true`, and
`lastError: null`. The local route always makes an authenticated, read-only
SyncHub status probe, even when every pending count is zero; it never uses a
legacy cmem.ai Pro status route and never appends or advances sync state.
Pending counts describe only writes made after the SyncHub launch baseline;
setup does not migrate a pre-launch local corpus.
If `hub.reachable` is false, report `hub.error`. If `lastError` is non-null,
report it too. Ask the user to verify the three values in **cmem.ai →
Connect**. Never include the token.
## 5. Report
Report device id, pending counts, last successful flush, Hub reachability and
checkpoint, and any Hub/flush error. End with this privacy note:
