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.

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 | $0.00252 | $0.03115 |
| Opus 5 | $0.00126 | $0.01558 |
| Sonnet 5 | $0.00050 | $0.00623 |
| Haiku 4.5 | $0.00025 | $0.00312 |
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 5d 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 — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 |
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.

nas-storage-setup is a skill published in the GitHub repository derekvery666/dsmctl (5 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 252 tokens to every session and 3,115 once invoked, about $0.0013 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.
