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 | $0.00000 | $0.00397 |
| Opus 5.5 | $0.00000 | $0.00159 |
| Sonnet 5.5 | $0.00000 | $0.00079 |
| Haiku 4.5 | $0.00000 | $0.00040 |
Grade A, and why
contextd-backup 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 1mo 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.
What it actually says
/contextd-backup — Backup Workspace
Tạo bản sao lưu local cho contextd config và Claude adapter artifacts trước khi upgrade.
CHECKPOINT 0 — Pre-check
Xác nhận tồn tại ít nhất một trong ~/.contextd/ hoặc ~/.claude/.
Nếu không tồn tại: dừng và báo rõ không có dữ liệu để backup.
CHECKPOINT 1 — Scope backup (in trước khi chạy)
In danh sách sẽ backup nếu tồn tại:
~/.contextd/config.json~/.claude/commands/~/.claude/agents/
Output backup:
~/.claude/backups/contextd-backup-{timestamp}.tgz(macOS/Linux)~/.claude/backups/contextd-backup-{timestamp}.zip(Windows PowerShell)
CHECKPOINT 2 — Xác nhận thực thi
Hỏi user xác nhận chạy backup ngay bây giờ. Chỉ chạy khi user đồng ý.
CHECKPOINT 3 — Chạy backup theo OS
- macOS/Linux: dùng
tar -czf - Windows PowerShell: dùng
Compress-Archive
Luôn tạo ~/.claude/backups/ nếu chưa có.
Compatibility
Legacy ~/.claude/wiki-global.json and ~/.claude/wiki-install-meta.json are included only as migration adapters. Canonical config is ~/.contextd/config.json.
CHECKPOINT 4 — Verify artifact
Sau khi chạy, bắt buộc verify:
- File backup tồn tại
- Kích thước file > 0
Nếu fail verify: báo lỗi, không báo thành công.
CHECKPOINT 5 — Kết quả
In:
Backup complete
- File: {backup_path}
- Created at (UTC): {timestamp}
- Next step: chạy /contextd-upgrade
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.

contextd-backup is a command published in the GitHub repository philngt/contextd (29 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 397 tokens. 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 2026-08-30.
