What is nas-storage-setup?

A guided procedure for giving a Synology NAS—the network computer used for shared storage—its first usable storage after DSM is installed.

Use it to detect the NAS setup state, finish the DSM first-run wizard if needed, and create the first storage pool and volume.

A NAS can appear set up while still having no storage pool or volume, so shared folders and other storage features cannot work. Creating storage may erase the selected disks and requires confirmation.

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	$0.00252	$0.03115
Opus 5.5	$0.00101	$0.01246
Sonnet 5.5	$0.00050	$0.00623
Haiku 4.5	$0.00025	$0.00312

Security

Grade A, and why

nas-storage-setup 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 2mo 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.

nas-storage-setup — give a DSM-installed NAS its first usable storage

Goal: take a NAS whose DSM is installed (admin exists, wizard maybe done) but which has no storage pool/volume to a working state with one all-disk volume mounted at /volume1. A fresh DSM marks itself "set up" with zero volumes, so it looks finished but nothing works — Storage Manager just prompts for a volume. Creating a storage pool permanently erases every disk it uses. Confirm with the user before any storage apply that creates or deletes a pool.

Live-verified on two Synology DS918+ (4-bay): 192.0.2.51 (DSM 7.3.2, fresh all-disk Btrfs RAID5 created from scratch) and 192.0.2.255 (DSM 7.3.1, kept its reused pool).

Relationship to nas-provision

nas-provision owns the admin account + first-run wizard and the whole password-vault security model. This skill assumes DSM is installed and reachable and picks up at storage. If the admin does not exist yet, run nas-provision first. The password rules below are the same ones nas-provision states — the model never sees or retrieves the DSM password; it lives in the OS credential store and only a human at a terminal reveals it.

0. Ask the user how to build the volume (the one decision point)

Storage layout is a real choice with a destructive, hard-to-undo result, so ask before building unless the user already specified it. Default and simplest: all disks → one Btrfs RAID5 volume. Offer the alternatives and the disk-count rules:

Layout	Min disks	Fault tolerance	Notes
RAID5 + Btrfs (default)	3	1 disk	Btrfs adds snapshots + self-healing; best general choice
SHR + Btrfs	1	1 disk (2+)	Synology hybrid RAID; flexible for mixed/upgraded disks
RAID6 + Btrfs	4	2 disks	Lower usable capacity
RAID10 + Btrfs	4 (even)	1 per mirror	Performance-oriented
RAID1 + Btrfs	2 (max 4)	n−1 disks	Mirror
ext4 variants	—	—	Only if the user does not want Btrfs

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.
