Gerrit

Gerrit Skill

This skill provides Gerrit code review integration using git-review with a Python wrapper for markdown-formatted query output on read/view operations. Action commands (submit, review, abandon) should use git-review or SSH commands directly.

Prerequisites

Install git-review: pip install git-review — docs

Authentication

git-review uses SSH for authentication with Gerrit servers.

# Configure Gerrit username (if different from local user)
git config --global gitreview.username yourgerrituser

# Test SSH connection
ssh -p 29418 youruser@review.example.com gerrit version

# Add SSH key to Gerrit
# 1. Generate SSH key if needed: ssh-keygen -t ed25519
# 2. Copy public key: cat ~/.ssh/id_ed25519.pub
# 3. Add to Gerrit: Settings > SSH Keys

Gerrit supports multiple authentication methods:

• SSH (recommended): Used by git-review for all operations
• HTTP/HTTPS: For web UI and REST API access (set password in Settings > HTTP Password)

See Gerrit Authentication for details.

Initial Setup

Configure Repository

# One-time setup for a repository
git review -s

# Or manually create .gitreview file in repository root
cat > .gitreview <<EOF
[gerrit]
host=review.example.com
port=29418
project=myproject
defaultbranch=main
EOF

See Installation Guide for details.

Script Usage

The wrapper script (scripts/gerrit.py) uses Gerrit SSH query commands and formats output as markdown. Connection details are read from .gitreview or provided via --host/--port/--username flags. See permissions.md for read/write classification of each command.

# Check Gerrit SSH access
$SKILL_DIR/scripts/gerrit.py check

# Changes
$SKILL_DIR/scripts/gerrit.py changes list
$SKILL_DIR/scripts/gerrit.py changes view 12345
$SKILL_DIR/scripts/gerrit.py changes diff 12345
$SKILL_DIR/scripts/gerrit.py changes diff 12345 --patchset 3
$SKILL_DIR/scripts/gerrit.py changes search "status:open project:myproject"

# Projects
$SKILL_DIR/scripts/gerrit.py projects list

All commands support --limit N for list commands (default 30).

Global connection options: --host, --port (default 29418), --username.

Commands (Direct git-review Usage)

For action commands, use git-review or SSH commands directly:

Submitting Changes

git review                          # Submit current branch for review
git review -t topic-name            # Submit with topic
git review -f                       # Submit and close local branch
git review --reviewers user1,user2  # Add reviewers
git review -n                       # Dry-run (show what would be done)

Full reference: git-review usage

Downloading Changes

git review -d 12345                 # Download change 12345
git review -d 12345,3               # Download patchset 3 of change 12345
git review -x 12345                 # Cherry-pick change (no branch)
git review -m 12345                 # Compare local changes to remote

Downloads create a local branch named review/username/topic.

Updating Changes

# Make changes to downloaded review
git commit --amend
git review                          # Upload new patchset

# Update to latest patchset
git review -d 12345                 # Re-download updates the branch

Advanced Options

git review -R                       # Don't rebase (submit as-is)
git review -D                       # Draft mode (WIP changes)
git review --no-cache               # Skip local cache
git review -v                       # Verbose output
git review --track                  # Track remote branch

Configuration

Per-Repository Settings

File: .gitreview (repository root)

[gerrit]
host=review.example.com
port=29418
project=myproject/subproject
defaultbranch=main
defaultremote=origin

Global Settings

# Set Gerrit username
git config --global gitreview.username myuser

# Set default remote
git config --global gitreview.remote gerrit

# Configure scheme (ssh/http/https)
git config --global gitreview.scheme ssh

Configuration stored in ~/.gitconfig

Examples

Daily Workflow

# Start work on new feature
git checkout -b feature-branch
# ... make changes ...
git commit -m "Add new feature"

# Submit for review
git review -t feature-topic
# Verify submission
$SKILL_DIR/scripts/gerrit.py changes list  # confirm change appears

# Address review comments
# ... make changes ...
git commit --amend
git review
# Verify new patchset uploaded
$SKILL_DIR/scripts/gerrit.py changes view <change-number>

Reviewing Others' Changes

# Download change for review
git review -d 12345
# Verify download
$SKILL_DIR/scripts/gerrit.py changes view 12345

# Test the change
# ... run tests, verify code ...

# Return to main branch
git checkout main
git branch -D review/user/topic

Working with Topics

# Submit with topic
git review -t authentication-refactor
# Verify submission
$SKILL_DIR/scripts/gerrit.py changes list

# All related changes will be grouped under this topic
git commit -m "Part 2: Update tests"
git review -t authentication-refactor

See common-workflows.md for more examples.

Advanced Usage

See advanced-usage.md for SSH commands, JSON output, and multi-server configuration.

Model Guidance

This skill wraps an official CLI. A fast, lightweight model is sufficient.

Troubleshooting
