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 | $0.00000 | $0.00312 |
| Opus 5 | $0.00000 | $0.00156 |
| Sonnet 5 | $0.00000 | $0.00062 |
| Haiku 4.5 | $0.00000 | $0.00031 |
Grade A, and why
sync 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 2d 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
/sync -- Bidirectional Memory Sync
Sync memory between your local machine and GitHub backup — both directions.
Usage
# Bidirectional: pull latest from GitHub, then push local changes
bash ~/.claude/scripts/hooks/memory-backup.sh sync
# Push only (same as /backup)
bash ~/.claude/scripts/hooks/memory-backup.sh push
# Pull only (same as /recover)
bash ~/.claude/scripts/hooks/memory-backup.sh pull
What sync does
- Pull —
git pullfrom GitHub, then distributerepo/memory/*.mdinto every localprojects/*/memory/directory (newer file wins) - Push — scan all local
projects/*/memory/directories, copy to the backup repo, commit, and push
When to use
- Switching between devices (laptop vs desktop) — run
/syncto get the other device's latest memory - After a long offline session — push your changes and pull anything new
- If you're unsure whether you have the latest —
/syncis always safe
Notes
- The pull step only overwrites files when the GitHub version is newer than the local version
- The SessionEnd hook auto-commits locally after every conversation
- This command handles the push + pull to remote (GitHub)
/backup= push only;/recover= pull only;/sync= both
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.

sync is a command published in the GitHub repository HelloRuru/claude-memory-engine (133 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 312 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.
