Code Sync

Use this skill to batch-sync all git repos across machines — pushing uncommitted changes at end of day or pulling latest at start of day. Invoke when the use...

Batch sync all git repos under a base directory — push (end-of-day) or pull (start-of-day). Default base directory: ~/code. Configurable via ~/.config/nini-skill/code-sync/config.md.

Prerequisites

Tool	Type	Required	Install
git	cli	Yes	brew install git or git-scm.com
git-workflow	skill	Yes	Included in npx skills add niracler/skill — must be invoked via Skill tool for all commits

Do NOT proactively verify these tools on skill load. If a command fails due to a missing tool, directly guide the user through installation and configuration step by step.

First-Time Setup

On first use, check for config at ~/.config/nini-skill/code-sync/config.md. If not found, ask the user:

1. "Where do you keep your git repos?" (default: ~/code)
2. "What's the directory structure?" — explain the expected pattern: <base-dir>/*/ for top-level repos and <base-dir>/*/repos/*/ for monorepo sub-repos
3. Save to ~/.config/nini-skill/code-sync/config.md:

base_dir: ~/code

Mode Selection

User says	Mode
「下班同步」or "push"	Push
「上班更新」or "pull"	Pull
「同步代码」「code-sync」	Ask user

Workflow (shared by both modes)

1. Scan → 2. Categorize → 3. Batch action (auto, no confirmation) → 4. Handle exceptions (interactive) → 5. Summary

If all repos are up-to-date, report that and stop.

Scan

bash scripts/scan.sh                          # Push: local data only (default ~/code)
bash scripts/scan.sh --fetch                  # Pull: fetch remote first (10s timeout/repo)
bash scripts/scan.sh --base-dir /path/to/dir  # Custom base directory

Output: JSON array with fields path, name, branch, remote, remote_url, dirty_count, has_upstream, ahead, behind, and fetch_error (only on --fetch failure).

Categorize

Push mode:

Category	Condition	Action
up-to-date	dirty_count == 0 && ahead == 0	Report
needs-push	dirty_count == 0 && ahead > 0	Auto git push
dirty	dirty_count > 0	Interactive
no-upstream	has_upstream == false	Ask user

Pull mode:

Category	Condition	Action
up-to-date	dirty_count == 0 && behind == 0	Report
needs-pull	dirty_count == 0 && behind > 0	Auto git pull --ff-only
dirty+behind	dirty_count > 0 && behind > 0	Interactive
fetch-error	fetch_error == true	Report, skip

Exception Handling

Situation	Steps
Dirty repo (push)	git diff --stat + git status → describe to user → ask: commit, stash, or skip. If commit, MUST invoke git-workflow skill via Skill tool — never run git commit directly.
No upstream (push)	Report → ask: set upstream and push (git push -u origin <branch>), or skip
ff-only fails (pull)	git log --oneline HEAD..@{u} + @{u}..HEAD → explain divergence → suggest: rebase, merge, or skip
Dirty + behind (pull)	Report both issues → ask: stash and pull (stash, pull --ff-only, pop), or skip

Summary

Group repos by outcome after all operations complete:

## {Push|Pull} Summary

{Pushed|Updated} (N):
  - repo-name (branch, N commits)
Already up-to-date (N):
  - repo-a, repo-b, ...
Resolved (N):
  - repo-c: action taken
Skipped (N):
  - repo-d: reason

Common Issues

Issue	Fix
scan.sh finds 0 repos	Check ~/code/*/ has git repos
fetch_error	Check network, SSH keys
ff-only fails	Rebase or merge manually
Push rejected	Pull first, then push
