群晖同步助手 · Synology Sync

Use this skill when the user wants to move local files to Synology, QuickConnect, DSM File Station, or a Synology Drive target directory, and expects the local source to be cleaned up only after a verified upload.

Triggers

Activate for requests such as:

• “把本地文件上传到群晖，成功后删本地”
• “用 QuickConnect 上传到 NAS”
• “清理 ~/Music/MP3 到群晖”
• “move local files to Synology and prune them”
• “upload to DSM File Station and delete the local copy”

Do not activate when

• The target is Synology C2 Object Storage, S3, or a non-DSM cloud drive.
• The user only wants to browse the NAS without moving local files.
• The user wants to publish, price, or modify this Skill rather than operate it.

Safety Invariants

1. Never delete local data before all applicable checks pass. The CLI verifies remote size and, by default, remote MD5 against the local MD5.
2. Default deletion mode is trash, not unlink. Files are moved under the configured trash directory and can be restored.
3. Use --delete-mode unlink only when the user explicitly asks for irreversible deletion.
4. Always run --dry-run first for a new source directory.
5. Treat QuickConnect as an access path, not as a storage API. If QuickConnect relay is unavailable, use a reachable --base-url (DDNS, VPN, Tailscale, or LAN address).
6. Never put the DSM password in a command line, config file, repository, or chat log. Use macOS Keychain or SYNO_PASSWORD for a one-off run.

Installed CLI

The deterministic CLI is installed at:

~/.local/bin/synology-cli

The source implementation and runtime live inside this skill:

~/.agents/skills/lov-sync-with-synology/scripts/synology_cli.py
~/.agents/skills/lov-sync-with-synology/.venv

Standard Workflow

1. Inspect the effective config without printing secrets:

synology-cli config

2. Validate connectivity and File Station API support:

synology-cli doctor

3. Plan the operation without changing the NAS or local files:

synology-cli run \
  --source ~/Music/MP3 \
  --remote-dir /home/Music/MP3 \
  --dry-run \
  --json

4. Run the verified move. The default trash mode is reversible:

synology-cli run \
  --source ~/Music/MP3 \
  --remote-dir /home/Music/MP3 \
  --delete-mode trash \
  --json

If the user explicitly requires irreversible local deletion after a successful upload and verification, use --delete-mode unlink instead. Do not silently upgrade a request from “清理” to unlink without confirming that the local copy is no longer needed.

5. Report the JSON summary and the audit log path. Do not claim success when ok is false or failed is non-zero.

Configuration

The default config path is:

~/.config/synology-cli/config.json

Key fields:

• quickconnect_id, quickconnect_domain
• base_url as an optional direct fallback
• username
• remote_dir
• cert_verify
• dsm_version
• delete_mode, verify_md5, recursive
• audit_log

The password is read from macOS Keychain by default:

security add-generic-password \
  -a "$USER" \
  -s synology-cli \
  -w 'REPLACE_WITH_DSM_PASSWORD' \
  -U

SYNO_PASSWORD is accepted for one-off automation, but it must never be written to a file or printed.

Verification

Use the repository-local fake DSM to test the full HTTPS API flow without touching a real NAS:

~/.agents/skills/lov-sync-with-synology/scripts/test_e2e.sh
