update-nanoclaw Efficiently bring upstream NanoClaw updates into a customized install, with preview, selective cherry-pick, and low token usage.

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/qwibitai/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
  • Source (src/): may conflict if you modified the same files
  • Build/config (package.json, tsconfig*.json, container/): review needed

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 preview: before merging, runs a dry-run (git merge --no-commit --no-ff) to show which files would conflict. You can still abort at this point.

Conflict resolution: opens only conflicted files, resolves the conflict markers, keeps your local customizations intact.

Validation: runs npm run build and npm test.

Rollback

The backup tag is printed at the end of each run:

git reset --hard pre-update-<hash>-<timestamp>

Backup branch backup/pre-update-<hash>-<timestamp> also exists.

Token usage

Only opens files with actual conflicts. Uses git log, git diff, and git status for everything else. Does not scan or refactor unrelated code.


Goal

Help a user with a customized NanoClaw install safely incorporate upstream changes without a fresh reinstall and without blowing tokens.

Operating principles

  • Never proceed with a dirty working tree.
  • Always create a rollback point (backup branch + tag) before touching anything.
  • Prefer git-native operations (fetch, merge, cherry-pick). Do not manually rewrite files except conflict markers.
  • Default to MERGE (one-pass conflict resolution). Offer REBASE as an explicit option.
  • Keep token usage low: rely on git status, git log, git diff, and open only conflicted files.

Step 0: Preflight (stop early if unsafe)

Run:

  • git status --porcelain If output is non-empty:
  • Tell the user to commit or stash first, then stop.

Confirm remotes:

  • git remote -v If upstream is missing:
  • Ask the user for the upstream repo URL (default: https://github.com/qwibitai/nanoclaw.git).
  • Add it: git remote add upstream <user-provided-url>
  • Then: git fetch upstream --prune

Determine the upstream branch name:

  • git branch -r | grep upstream/
  • If upstream/main exists, use main.
  • If only upstream/master exists, use master.
  • Otherwise, ask the user which branch to use.
  • Store this as UPSTREAM_BRANCH for all subsequent commands. Every command below that references upstream/main should use upstream/$UPSTREAM_BRANCH instead.

Fetch:

  • git fetch upstream --prune

Step 1: Create a safety net

Capture current state:

  • HASH=$(git rev-parse --short HEAD)
  • TIMESTAMP=$(date +%Y%m%d-%H%M%S)

Create backup branch and tag (using timestamp to avoid collisions on retry):

  • git branch backup/pre-update-$HASH-$TIMESTAMP
  • git tag pre-update-$HASH-$TIMESTAMP

Save the tag name for later reference in the summary and rollback instructions.

Step 2: Preview what upstream changed (no edits yet)

Compute common base:

  • BASE=$(git merge-base HEAD upstream/$UPSTREAM_BRANCH)

Show upstream commits since BASE:

  • git log --oneline $BASE..upstream/$UPSTREAM_BRANCH

Show local commits since BASE (custom drift):

  • git log --oneline $BASE..HEAD

Show file-level impact from upstream:

  • git diff --name-only $BASE..upstream/$UPSTREAM_BRANCH

Bucket the upstream changed files:

  • Skills (.claude/skills/): unlikely to conflict unless the user edited an upstream skill
  • Source (src/): may conflict if user modified the same files
  • Build/config (package.json, package-lock.json, tsconfig*.json, container/, launchd/): review needed
  • Other: docs, tests, misc

Present these buckets to the user and ask them to choose one path using AskUserQuestion:

  • A) Full update: merge all upstream changes
  • B) Selective update: cherry-pick specific upstream commits
  • C) Abort: they only wanted the preview
  • D) Rebase mode: advanced, linear history (warn: resolves conflicts per-commit)

If Abort: stop here.

Step 3: Conflict preview (before committing anything)

If Full update or Rebase:

  • Dry-run merge to preview conflicts. Run these as a single chained command so the abort always executes:
    git merge --no-commit --no-ff upstream/$UPSTREAM_BRANCH; git diff --name-only --diff-filter=U; git merge --abort
    
  • If conflicts were listed: show them and ask user if they want to proceed.
  • If no conflicts: tell user it is clean and proceed.

Step 4A: Full update (MERGE, default)

Run:

  • git merge upstream/$UPSTREAM_BRANCH --no-edit

If conflicts occur:

  • Run git status and identify conflicted files.
  • For each conflicted file:
    • Open the file.
    • Resolve only conflict markers.
    • Preserve intentional local customizations.
    • Incorporate upstream fixes/improvements.
    • Do not refactor surrounding code.
    • git add <file>
  • When all resolved:
    • If merge did not auto-commit: git commit --no-edit

Step 4B: Selective update (CHERRY-PICK)

If user chose Selective:

  • Recompute BASE if needed: BASE=$(git merge-base HEAD upstream/$UPSTREAM_BRANCH)
  • Show commit list again: git log --oneline $BASE..upstream/$UPSTREAM_BRANCH
  • Ask user which commit hashes they want.
  • Apply: git cherry-pick <hash1> <hash2> ...

If conflicts during cherry-pick:

  • Resolve only conflict markers, then:
    • git add <file>
    • git cherry-pick --continue If user wants to stop:
    • git cherry-pick --abort

Step 4C: Rebase (only if user explicitly chose option D)

Run:

  • git rebase upstream/$UPSTREAM_BRANCH

If conflicts:

  • Resolve conflict markers only, then:
    • git add <file>
    • git rebase --continue If it gets messy (more than 3 rounds of conflicts):
    • git rebase --abort
    • Recommend merge instead.

Step 5: Validation

Run:

  • npm run build
  • npm test (do not fail the flow if tests are not configured)

If build fails:

  • Show the error.
  • Only fix issues clearly caused by the merge (missing imports, type mismatches from merged code).
  • Do not refactor unrelated code.
  • If unclear, ask the user before making changes.

Step 6: Summary + rollback instructions

Show:

  • Backup tag: the tag name created in Step 1
  • New HEAD: git rev-parse --short HEAD
  • Upstream HEAD: git rev-parse --short upstream/$UPSTREAM_BRANCH
  • Conflicts resolved (list files, if any)
  • Remaining local diff vs upstream: git diff --name-only upstream/$UPSTREAM_BRANCH..HEAD

Tell the user:

  • To rollback: git reset --hard <backup-tag-from-step-1>
  • Backup branch also exists: backup/pre-update-<HASH>-<TIMESTAMP>
  • Restart the service to apply changes:
    • If using launchd: launchctl unload ~/Library/LaunchAgents/com.nanoclaw.plist && launchctl load ~/Library/LaunchAgents/com.nanoclaw.plist
    • If running manually: restart npm run dev
