Cloud Sync

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:

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:

• sync token;
• user id;
• 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:

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

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:
