A first-run setup guide for connecting the synology-mgmt plugin to a Synology NAS, a network storage device. It records the NAS address, SSH access, web address and shared-folder location.

Use it when setting up the plugin, changing NAS connection details, or preparing it for a different NAS.

It gives later NAS-management tasks the connection details they need without placing those details in each task.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add danielrosehill/Synology-Mgmt-Plugin --skill onboard

Clone the repo

git clone --depth 1 https://github.com/danielrosehill/Synology-Mgmt-Plugin

Made for: Claude Code.

Or install synology-mgmt, the plugin that ships this one along with the rest of its 2 skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00105	$0.01273
Opus 5	$0.00053	$0.00636
Sonnet 5	$0.00021	$0.00255
Haiku 4.5	$0.00011	$0.00127

Security

Grade A, and why

onboard scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

synology-mgmt: onboard

Establish the persistent connection profile for a Synology NAS. The same plugin install can serve multiple NAS environments — only the values in config.json are environment-specific. No host details should ever be hard-coded into other skills in this plugin.

Workspace resolution

Resolve the plugin's data directory as $CLAUDE_USER_DATA/synology-mgmt/ if CLAUDE_USER_DATA is set; otherwise $XDG_DATA_HOME/claude-plugins/synology-mgmt/ if XDG_DATA_HOME is set; otherwise ~/.local/share/claude-plugins/synology-mgmt/. Create the directory if it doesn't exist. See the canonical convention in the claude-rudder:plugin-data-storage skill.

Shell form:

PLUGIN_DATA_DIR="${CLAUDE_USER_DATA:-${XDG_DATA_HOME:-$HOME/.local/share}/claude-plugins}/synology-mgmt"
mkdir -p "$PLUGIN_DATA_DIR"

The config file is $PLUGIN_DATA_DIR/config.json.

When to use

User says "set up synology", "onboard nas", "configure synology plugin".
Any other synology-mgmt skill finds no config.json at the resolved path — offer to run onboarding first.
The user changes NAS, IPs, or SSH credentials.

Prerequisites

SSH service enabled in DSM: Control Panel → Terminal & SNMP → Enable SSH service.
The user has an admin or administrators-group account that can SSH in.

Procedure

Load existing config from $PLUGIN_DATA_DIR/config.json if present. Show the current values back. Offer Update vs Replace vs Cancel.

Interview the user. Ask each question; default sensibly when the user just hits enter:

Field	Prompt	Notes
`host`	"What's the LAN address of your NAS?"	No default — the user must answer. Accept hostname or IP.
`ssh_user`	"SSH username?"	Default: `admin`. Synology blocks `root` SSH by default.
`ssh_port`	"SSH port?"	Default: `22`. Some users move it.
`ssh_key_path`	"Path to the SSH private key (or leave blank for default agent)?"	Optional. Expand `~`.
`dsm_web_url`	"DSM web URL (with port)?"	Default: `http://<host>:5000` (HTTPS DSM is usually on `:5001`).
`volume_root`	"Primary volume mount point on the NAS?"	Default: `/volume1`.
`model`	"NAS model (e.g. DS923+, DS1522+)?"	Optional but useful for context.
`dsm_version`	"DSM version (e.g. 7.2)?"	Optional.
`dsm_user_ref`	"Where is the DSM admin password stored, if you want skills to use the DSM API? (1Password ref / env var name / blank)"	Reference only.
`notes`	"Any free-text notes about this NAS?"	Optional (e.g. RAID layout, attached UPS).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

onboard is a skill published in the GitHub repository danielrosehill/Synology-Mgmt-Plugin (7 stars, last pushed 4mo ago), licensed MIT. It adds 105 tokens to every session and 1,273 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
