sync-enable

A setup command that enables automatic syncing of Claude Code sessions to a private GitHub repository. GitHub is an online service for storing code and working with others.

In plain words
What is it for?
Use it to check GitHub CLI access, create the private session repository if needed, and turn on automatic syncing when sessions end.
Why use it?
It lets you continue a coding session on another device or in Claude Web, Desktop, or Mobile without manually moving its session data.

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.

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.

Security

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 3d 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

  1. Verifies GitHub CLI is installed and authenticated
  2. Creates a private claude-sessions repository (if needed)
  3. 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 /sync to manually sync anytime
  • Use /sessions to list synced sessions
  • Use /sync-disable to turn off

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.
