Instructions for creating a three-layer encrypted store for real, identifiable session data. The layers are device encryption, a separate encrypted storage area, and per-file encryption using sops and age.

Use it to check and configure FileVault, an encrypted data store, and separate encryption keys for transcripts or other identifiable records.

It reduces the risk that a lost device, another application, cloud syncing, or a single exposed password will reveal sensitive session files.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.

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	$0.00176	$0.01107
Opus 5.5	$0.00070	$0.00443
Sonnet 5.5	$0.00035	$0.00221
Haiku 4.5	$0.00018	$0.00111

Security

Grade B, and why

vault scanned grade B with 1 finding 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/vault.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

confide:vault — the THREE LOCKS for storing RED data

Operationalizes the defense-in-depth storage posture in confide/docs/THREE-LOCKS.md: real (RED) transcripts rest behind three independent locks, so compromising one does not expose a client. To read a real transcript an attacker needs the device password AND the encrypted-store password AND the age key — three separate secrets, ideally held in different places.

Lock	What	Protects against
1 — Device	FileVault full-disk encryption + strong login password + short auto-lock	a lost/stolen/USB-booted machine
2 — Store	RED in a dedicated ENCRYPTED store (encrypted APFS volume / AES-256 `.dmg`), NOT in Documents and NEVER in iCloud/Dropbox	other apps, other users, silent cloud sync
3 — Per-file	each RED file `sops`/`age`-encrypted at rest, age key stored SEPARATELY; processing in a no-network VM/container	files individually sealed; key not beside the data

NON-DESTRUCTIVE — read before running

--check (the default) runs only read-only probes: fdesetup status, shutil.which(sops/age), and os.path.exists(...). It never moves, deletes, or encrypts data and never runs fdesetup enable, hdiutil, age-keygen, or rm.
It reports each lock ✓/✗ and prints the exact command to fix every ✗ — for the user to review and run themselves.
--init-age generates an age key only with that explicit flag, and never overwrites an existing key.
--init-store PATH only prints the encrypted-store creation command; it does not execute disk-image creation. Refuses cloud-synced paths.
Never move, encrypt, or delete the user's RED data on their behalf without explicit confirmation. There is no destructive default.

Run it

# default = read-only status check + checklist with fix commands
python3 skills/vault/scripts/vault.py --check
python3 skills/vault/scripts/vault.py --json            # structured status dict

# point at your own RED store to verify it's not cloud-synced
python3 skills/vault/scripts/vault.py --store-path ~/CONFIDE-RED.dmg

# optional, GUARDED helpers (explicit flags only)
python3 skills/vault/scripts/vault.py --init-age        # make an age key (never overwrites)
python3 skills/vault/scripts/vault.py --init-store ~/CONFIDE-RED.dmg   # prints the hdiutil command

vault is a skill published in the GitHub repository glebis/claude-skills (409 stars, last pushed yesterday), licensed MIT. It adds 176 tokens to every session and 1,107 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
