update-nanoclaw

# About Your NanoClaw fork drifts from upstream as you customize it. This skill pulls upstream changes into your install without losing your modifications. Run `/update-nanoclaw` in Claude Code. ## How it works **Preflight**: checks for clean working tree (`git status --porcelain`). If `upstream` remote is missing, asks you for the URL (defaults to `https://github.com/nanocoai/nanoclaw.git`) and adds it. Detects the upstream branch name (`main` or `master`). **Backup**: creates a timestamped backup branch and tag (`backup/pre-update-<hash>-<timestamp>`, `pre-update-<hash>-<timestamp>`) before touching anything. Safe to run multiple times. **Preview**: runs `git log` and `git diff` against the merge base to show upstream changes since your last sync. Groups changed files into categories: - **Skills** (`.claude/skills/`): unlikely to conflict unless you edited an upstream skill - **Host source** (`src/`): may conflict if you modified the same files - **Container** (`container/`): triggers container rebuild - **Build/config** (`package.json`, `pnpm-lock.yaml`, `tsconfig*.json`): lockfile changes trigger dep install **Update paths** (you pick one): - `merge` (default): `git merge upstream/<branch>`. Resolves all conflicts in one pass. - `cherry-pick`: `git cherry-pick <hashes>`. Pull in only the commits you want. - `rebase`: `git rebase upstream/<branch>`. Linear history, but conflicts resolve per-commit. - `abort`: just view the changelog, change nothing. **Conflict prev...
