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 and points the user to the installer's cmem.ai sign-in, which writes the connection.

**Security rule:** never ask the user to paste the sync token into this chat, and never put it in a command you write, print it, put it in argv, or log it. A secret pasted into a chat lands in the transcript, which claude-mem itself can capture and sync. The installer writes the token to `~/.claude-mem/settings.json` (mode `0600`) without it ever passing through this conversation.

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)}"
# With CLAUDE_MEM_LOCAL_API_TOKEN set, the worker wants the token: node prints the header from
# settings.json (nothing when unset) and curl reads it from stdin, so it stays out of argv and chat.
node -e "try{const t=String(JSON.parse(require('fs').readFileSync(require('path').join(require('os').homedir(),'.claude-mem','settings.json'),'utf-8')).CLAUDE_MEM_LOCAL_API_TOKEN||'').trim();if(t)process.stdout.write('X-Claude-Mem-Token: '+t+'\\n')}catch{}" | curl -s -H @- "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. Connect through the installer

Ask the user to run this in their own terminal:

npx claude-mem install

and to choose **CMEM Pro** when the installer asks. The installer signs them in through the browser (they approve a device code), then writes the sync token, user id and SyncHub URL into `~/.claude-mem/settings.json` itself and restarts the worker. Nothing secret is typed into this chat.

If the user cannot run the installer interactively (CI, a remote box), point them to the headless setup guide, https://docs.claude-mem.ai/cmem-pro-headless, and let them apply its manual recipe in their own terminal or editor. Do not collect the values yourself.

The worker mints and persists a device id on first start and defaults the device name to the hostname.

3. Verify

Once the installer finishes, poll the status route every five seconds for up to 30 seconds. If the worker was not restarted, restart it first:

node -e "try{const t=String(JSON.parse(require('fs').readFileSync(require('path').join(require('os').homedir(),'.claude-mem','settings.json'),'utf-8')).CLAUDE_MEM_LOCAL_API_TOKEN||'').trim();if(t)process.stdout.write('X-Claude-Mem-Token: '+t+'\\n')}catch{}" | curl -s -H @- -X POST "http://127.0.0.1:${PORT}/api/admin/restart"

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, and suggest running `npx claude-mem install` again to refresh the connection. Never include the token.

4. Report

Report device id, pending counts, last successful flush, Hub reachability and checkpoint, and any Hub/flush error. End with this privacy note:
