Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00010 | $0.00181 |
| Opus 5.5 | $0.00004 | $0.00072 |
| Sonnet 5.5 | $0.00002 | $0.00036 |
| Haiku 4.5 | $0.00001 | $0.00018 |
Grade A, and why
sync-enable 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 2mo 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
Enable Session Sync
Enable automatic syncing of Claude Code sessions to GitHub. This allows you to continue sessions in Claude Web/Desktop/Mobile.
What This Does
- Verifies GitHub CLI is installed and authenticated
- Creates a private
claude-sessionsrepository (if needed) - Enables automatic sync on session end
Run Setup
bash .claude/scripts/enable-sync.sh
After Setup
- Sessions automatically sync when you exit Claude Code
- Use

/sessionsto list synced sessions - Use
/sync-disableto turn off
Requirements
- GitHub CLI (
gh) installed: https://cli.github.com/ - Authenticated:
gh auth login
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.
