What is snapshot-config?

A skill for exporting and saving snapshots of application settings on Windows 11, macOS, or Ubuntu Linux. A snapshot is a stored copy of configuration that can help recreate a setup on another machine.

Use it to save editor, terminal, shell, package-manager, and development-tool configurations, with optional setup recommendations.

Application settings are easy to lose when moving computers or reinstalling software. Keeping snapshots in a separate user-chosen folder prevents plugin updates from deleting them.

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	$0.00135	$0.02290
Opus 5.5	$0.00054	$0.00916
Sonnet 5.5	$0.00027	$0.00458
Haiku 4.5	$0.00014	$0.00229

Security

Grade A, and why

snapshot-config 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 25d 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.

Snapshot Config — Export และแนะนำการตั้งค่าโปรแกรม

คุณทำหน้าที่ช่วย export config ของโปรแกรม พร้อมแนะนำการตั้งค่าที่เหมาะสมตาม OS และ workflow ของผู้ใช้ ผลลัพธ์คือ snapshot ที่สามารถนำไป restore บนเครื่องใหม่ได้ทันที ปฏิบัติตามกฎทุกข้อด้านล่างอย่างเคร่งครัด

Core Rules (Non-negotiable)

ตรวจสอบ config path ก่อนเสมอ — อ่าน ~/.config/claude-utility/settings.json ทุกครั้ง ไม่ hardcode ~/.claude/claude-utility/snapshots/ ยกเว้นเป็น default ที่ผู้ใช้เลือก
ถามก่อนถ้าไม่รู้ชื่อโปรแกรม — อย่าเดาชื่อโปรแกรมเอง
ห้ามแตะ/บันทึก sensitive data เด็ดขาด — ถ้า config มี token, password, private key ต้องระบุว่า "ไม่ควร snapshot ค่านี้" และ redact ออกก่อน save ทุกครั้ง ไม่มีข้อยกเว้น
อธิบายเหตุผลทุกคำแนะนำ — ไม่แนะนำแบบ "ควรตั้งค่านี้" โดยไม่มีเหตุผลประกอบ
แยก must / nice-to-have ให้ชัดเจนเสมอ — บอกชัดว่าอันไหนสำคัญ อันไหนแล้วแต่ preference
บอก path เต็มที่ save snapshot ให้ผู้ใช้ทราบเสมอ หลังบันทึกสำเร็จ

Supporting files

Config File — บันทึก path ที่ผู้ใช้กำหนดไว้ที่ ~/.config/claude-utility/settings.json รูปแบบ:
```
{
  "snapshots_base_path": "/path/to/snapshots/",
  "os_profile_path": "/path/to/os-profile.md"
}
```
references/config-paths.md — หา config file location ของโปรแกรม
references/install-paths.md — หา recommended installation path ต่อ OS
os-profile.md (จาก utility:os-design) — context เรื่อง OS/path/software ของผู้ใช้ ถ้ามี

Workflow

1. รับชื่อโปรแกรม

ถ้าผู้ใช้ยังไม่ได้บอกชื่อโปรแกรม ให้ถาม (Core Rules ข้อ 2):

"ต้องการ snapshot config ของโปรแกรมอะไร?"

2. ตรวจสอบ Path + โหลด Context

ขั้นตอนตรวจสอบ path (ทำก่อนดาวน์โหลดทุกครั้ง)

อ่านไฟล์ ~/.config/claude-utility/settings.json
ถ้า ไม่มีไฟล์ (ใช้ครั้งแรก) → ถามผู้ใช้ว่าต้องการบันทึก snapshot ที่ folder ไหน พร้อมบอก default ว่า ~/.claude/claude-utility/snapshots/ แล้ว สร้าง config file บันทึก path ที่เลือก จากนั้นดำเนินการต่อ (ไม่ใช้ path ใต้ plugins/utility/ เพราะโฟลเดอร์นั้นอยู่ใน plugin cache ที่ถูกแทนที่ทุกครั้งที่อัปเดต version)
ถ้า มีไฟล์แล้ว → ใช้ snapshots_base_path จาก config โดยตรง ไม่ต้องถามซ้ำ
ถ้าผู้ใช้ระบุ path ในข้อความ (เช่น "snapshot ไปไว้ที่ D:/Backup") → ใช้ path นั้นสำหรับครั้งนี้เท่านั้น ไม่ overwrite config

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
