Doro Git Essentials

Essential Git commands and workflows for version control, branching, and collaboration.

Security Scan

This is an instruction-only Git cheat-sheet; its requirements and instructions are coherent with its stated purpose, but it contains normal Git commands that can modify or delete local and remote repository state so use the destructive commands carefully.

Purpose & Capability

Name and description match the contents: the skill is a Git command reference and it only requires the 'git' binary. There are no unrelated credentials, binaries, or config paths requested.

Instruction Scope

SKILL.md is a straightforward Git guide. It instructs running commands that modify local state (~/.gitconfig via git config --global, working tree, commits, branches) and remote state (git push, git push --force, git remote set-url). These are expected for a Git guide but are potentially destructive; the skill does not try to read unrelated files or send data to external endpoints beyond standard git remotes.

Install Mechanism

No install spec and no code files — lowest-risk form. Note: registry metadata at the top of the package and the embedded _meta.json show different ownerId/slug values (registry: 'doro-git-essentials', ownerId kn7ervna...; _meta.json: slug 'git-essentials', ownerId kn7anq2d...), which is a minor inconsistency in metadata but does not affect behavior since there is no install step or external download.

Credentials

No environment variables, credentials, or config paths are requested. The SKILL.md does not reference secrets or access tokens. The only side-effects are standard git operations that use whatever repo/remotes the user provides.

Persistence & Privilege

always is false and the skill is user-invocable. It does not request permanent presence or modify other skills or system-wide settings. The only persistent change it suggests is modifying the user's Git config (~/.gitconfig), which is expected for initial Git setup.

Assessment

This skill is an offline instruction-only Git reference (no code to install, no external downloads, no credentials requested). It is coherent with its purpose. Before using it: (1) be aware many commands are destructive (git reset --hard, git push --force, git clean -fdx) and will alter or permanently remove local/remote data — run them only if you understand the effect; (2) git config --global writes to ~/.gitconfig (expected); (3) verify the publisher/owner if provenance matters — the embedded _meta.json differs from the registry metadata (slug/ownerId mismatch), which is a packaging inconsistency (not a behavioral risk here but worth confirming); (4) because the skill can be invoked by an agent, avoid allowing automated runs to execute destructive commands on repositories you care about.

Git Essentials

Essential Git commands for version control and collaboration.

Initial Setup

# Configure user
git config --global user.name "Your Name"
git config --global user.email "[e-mail]"

# Initialize repository
git init

git add .
git add -A  # All changes including deletions

# Commit changes
git commit -m "Commit message"

# Add and commit in one step
git commit -am "Message"

# Amend last commit
git commit --amend -m "New message"
git commit --amend --no-edit  # Keep message

Viewing changes

Merging

# Merge branch into current
git merge feature-name

# Merge with no fast-forward
git merge --no-ff feature-name

# Abort merge
git merge --abort

# Show merge conflicts
git diff --name-only --diff-filter=U

Remote Operations

Managing remotes

# List remotes
git remote -v

# Add remote
git remote add origin https://github.com/user/repo.git

# Change remote URL
git remote set-url origin https://github.com/user/new-repo.git

# Remove remote
git remote remove origin

Syncing with remote

# Fetch from remote
git fetch origin

# Pull changes (fetch + merge)
git pull

# Pull with rebase
git pull --rebase

# Push changes
git push

# Push new branch
git push -u origin branch-name

# Force push (careful!)
git push --force-with-lease

History & Logs

Viewing history

# Show commit history
git log

# One line per commit
git log --oneline

# With graph
git log --graph --oneline --all

# Last N commits
git log -5

# Commits by author
git log --author="Name"

# Commits in date range
git log --since="2 weeks ago"
git log --until="2024-01-01"

# File history
git log -- file.txt

Searching history

# Search commit messages
git log --grep="bug fix"

# Search code changes
git log -S "function_name"

# Show who changed each line
git blame file.txt

# Find commit that introduced bug
git bisect start
git bisect bad
git bisect good commit-hash

Undoing Changes

Working directory

# Discard changes in file
git restore file.txt
git checkout -- file.txt  # Old way

# Discard all changes
git restore .

Staging area

# Unstage file
git restore --staged file.txt
git reset HEAD file.txt  # Old way

# Unstage all
git reset

Commits

# Undo last commit (keep changes)
git reset --soft HEAD~1

# Undo last commit (discard changes)
git reset --hard HEAD~1

# Revert commit (create new commit)
git revert commit-hash

# Reset to specific commit
git reset --hard commit-hash

Stashing

# Stash changes
git stash

# Stash with message
git stash save "Work in progress"

# List stashes
git stash list

# Apply latest stash
git stash apply

# Apply and remove stash
git stash pop

# Apply specific stash
git stash apply stash@{2}

# Delete stash
git stash drop stash@{0}

# Clear all stashes
git stash clear

Rebasing

# Rebase current branch
git rebase main

# Interactive rebase (last 3 commits)
git rebase -i HEAD~3

# Continue after resolving conflicts
git rebase --continue

# Skip current commit
git rebase --skip

# Abort rebase
git rebase --abort

Tags

# List tags
git tag

# Create lightweight tag
git tag v1.0.0

# Create annotated tag
git tag -a v1.0.0 -m "Version 1.0.0"

# Tag specific commit
git tag v1.0.0 commit-hash

# Push tag
git push origin v1.0.0

# Push all tags
git push --tags

# Delete tag
git tag -d v1.0.0
git push origin --delete v1.0.0

Advanced Operations

Cherry-pick

# Apply specific commit
git cherry-pick commit-hash

# Cherry-pick without committing
git cherry-pick -n commit-hash

Submodules

# Add submodule
git submodule add https://github.com/user/repo.git path/

# Initialize submodules
git submodule init

# Update submodules
git submodule update

# Clone with submodules
git clone --recursive https://github.com/user/repo.git

Clean

# Preview files to be deleted
git clean -n

# Delete untracked files
git clean -f

# Delete untracked files and directories
git clean -fd

# Include ignored files
git clean -fdx

Common Workflows

Feature branch workflow:

git checkout -b feature/new-feature
# Make changes
git add .
git commit -m "Add new feature"
git push -u origin feature/new-feature
# Create PR, then after merge:
git checkout main
git pull
git branch -d feature/new-feature

Hotfix workflow:

git checkout main
git pull
git checkout -b hotfix/critical-bug
# Fix bug
git commit -am "Fix critical bug"
git push -u origin hotfix/critical-bug
# After merge:
git checkout main && git pull

Syncing fork:

git remote add upstream https://github.com/original/repo.git
git fetch upstream
git checkout main
git merge upstream/main
git push origin main

Useful Aliases

Add to ~/.gitconfig:

[alias]
    st = status
    co = checkout
    br = branch
    ci = commit
    unstage = reset HEAD --
    last = log -1 HEAD
    visual = log --graph --oneline --all
    amend = commit --amend --no-edit

Tips

• Commit often, perfect later (interactive rebase)
• Write meaningful commit messages
• Use .gitignore for files to exclude
• Never force push to shared branches
• Pull before starting work
• Use feature branches, not main
• Rebase feature branches before merging
• Use --force-with-lease instead of --force

Common Issues

Undo accidental commit:

git reset --soft HEAD~1

Recover deleted branch:

git reflog
git checkout -b branch-name <commit-hash>

Fix wrong commit message:

git commit --amend -m "Correct message"

Resolve merge conflicts:

# Edit files to resolve conflicts
git add resolved-files
git commit  # Or git merge --continue
