Sync your Claude brain - memory, skills, agents, and rules across machines and teammates via Git. One command to share context. One command to inherit it.
SaferSkills independently audited claude-sync (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.
text (not bash) so it reads as prose, not a command.```bash

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Sync the user's Claude brain across machines and teammates. Read skills/claude-sync/REFERENCE.md before running any command — it contains the full protocol for each operation including safety rules, conflict resolution policy, and the secrets-scrubbing contract.
| Layer | Path (global) | Path (project) |
|---|---|---|
| Memory | ~/.claude/memory/ | .claude/memory/ |
| Skills | ~/.claude/skills/ | .claude/skills/ |
| Agents | ~/.claude/agents/ | .claude/agents/ |
| Rules | ~/.claude/CLAUDE.md | ./CLAUDE.md |
| Settings | ~/.claude/settings.json | — |
Settings are scrubbed before sync. Only permissions, hooks, theme, and model travel. API keys, tokens, and .env files never leave the machine.
Before running anything, identify which operation the user wants:
initpushpulldiffmerge <name>watchstatusIf intent is ambiguous, ask one clarifying question before proceeding.
All operations delegate to skills/claude-sync/scripts/sync.sh:
~/.claude/skills/claude-sync/scripts/sync.sh <command> [args]If the script is not yet installed (first run on a machine), guide the user through init first, which sets up the sync repo and installs the script.
Every operation must end with a structured summary. Use this exact format — fill in real values, never placeholders:
┌─────────────────────────────────────────────┐
│ claude-sync — <operation> complete │
├─────────────────────────────────────────────┤
│ Memory files : <n> │
│ Skills : <n> │
│ Agents : <n> │
│ Branch : brain/<username> │
│ Remote : <host> │

└─────────────────────────────────────────────┘says otherwise.
| Condition | What to do |
|---|---|
| Remote unreachable | Show the configured remote URL, suggest checking network |
git not installed | Link to https://git-scm.com and stop |
| Merge conflict | Show conflicting files, apply local-wins policy, explain why |
jq missing | Warn that settings merge will be skipped, proceed without it |
| Lock file exists | Show the PID, explain how to remove /tmp/claude-sync.lock |
| Empty remote | Normal on first push — explain and continue |
