RU - Repo Updater

A comprehensive Bash CLI for synchronizing dozens or hundreds of GitHub repositories. Beyond basic sync, RU includes a full AI-assisted code review system and agent-sweep capability for automatically processing uncommitted changes across your entire projects directory.

Why This Exists

When you work with 47+ repos (personal projects, forks, dependencies), keeping them synchronized manually is tedious. But synchronization is just the beginning—RU also orchestrates AI coding agents to review issues, process PRs, and commit uncommitted work at scale.

The problem it solves:

• Manual cd ~/project && git pull for each repo
• Missing updates that accumulate into merge conflicts
• Dirty repos that never get committed
• Issues and PRs that pile up across repositories
• No coordination for AI agents working across repos

Critical Concepts

Git Plumbing, Not Porcelain

RU uses git plumbing commands exclusively—never parses human-readable output:

# WRONG: Locale-dependent, version-fragile
git pull 2>&1 | grep "Already up to date"

# RIGHT: Machine-readable plumbing
git rev-list --left-right --count HEAD...@{u}
git status --porcelain
git rev-parse HEAD

Stream Separation

Human-readable output goes to stderr; data to stdout:

ru sync --json 2>/dev/null | jq '.summary'
# Progress shows in terminal, JSON pipes to jq

No Global cd

All git operations use git -C. Never changes working directory.

Essential Commands

Sync (Primary Use Case)

# Sync all configured repos
ru sync

# Parallel sync (much faster)
ru sync -j8

# Dry run - see what would happen
ru sync --dry-run

# Resume interrupted sync
ru sync --resume

# JSON output for scripting
ru sync --json 2>/dev/null | jq '.summary'

Status (Read-Only Check)

# Check all repos without modifying
ru status

# JSON output
ru status --json

Repo Management

# Initialize configuration
ru init

# Add repos to sync list
ru add owner/repo
ru add https://github.com/owner/repo
ru add owner/repo@branch as custom-name

# Remove from list
ru remove owner/repo

# List configured repos
ru list

# Detect orphaned repos (in projects dir but not in list)
ru prune           # Preview
ru prune --delete  # Actually remove
ru prune --archive # Move to archive directory

Diagnostics

ru doctor      # System health check
ru self-update # Update ru itself

AI-Assisted Review System

RU includes a powerful review orchestration system for managing AI-assisted code review across your repositories.

Two-Phase Review Workflow

Phase 1: Discovery (--plan)

• Queries GitHub for open issues and PRs across all repos
• Scores items by priority using label analysis and age
• Creates isolated git worktrees for safe review
• Spawns Claude Code sessions in terminal multiplexer

Phase 2: Application (--apply)

• Reviews proposed changes from discovery phase
• Runs quality gates (ShellCheck, tests, lint)
• Optionally pushes approved changes (--push)

# Discover and plan reviews
ru review --plan

# After reviewing AI suggestions
ru review --apply --push

Priority Scoring Algorithm

| Factor | Points | Logic | |--------|--------|-------| | Type | 0-20 | PRs: +20, Issues: +10, Draft PRs: -15 | | Labels | 0-50 | security/critical: +50, bug/urgent: +30 | | Age (bugs) | 0-50 | >60 days: +50, >30 days: +30 | | Recency | 0-15 | Updated <3 days: +15, <7 days: +10 | | Staleness | -20 | Recently reviewed: -20 |

Priority levels: CRITICAL (≥150), HIGH (≥100), NORMAL (≥50), LOW (<50)

Session Drivers

| Driver | Description | Best For | |--------|-------------|----------| | auto | Auto-detect best available | Default | | ntm | Named Tmux Manager integration | Multi-agent workflows | | local | Direct tmux sessions | Simple setups |

ru review --mode=ntm --plan
ru review -j 4 --plan  # Parallel sessions

Cost Budgets

ru review --max-repos=10 --plan
ru review --max-runtime=30 --plan  # Minutes
ru review --skip-days=14 --plan    # Skip recently reviewed
ru review --analytics              # View past review stats

Agent Sweep (Automated Dirty Repo Processing)

The ru agent-sweep command orchestrates AI coding agents to automatically process repositories with uncommitted changes.

Basic Usage

# Process all repos with uncommitted changes
ru agent-sweep

# Dry run - preview what would be processed
ru agent-sweep --dry-run

# Process 4 repos in parallel
ru agent-sweep -j4

# Filter to specific repos
ru agent-sweep --repos="myproject*"

# Include release step after commit
ru agent-sweep --with-release

# Resume interrupted sweep
ru agent-sweep --resume

# Start fresh
ru agent-sweep --restart

Three-Phase Agent Workflow

Phase 1: Planning (--phase1-timeout, default 300s)

• Claude Code analyzes uncommitted changes
• Determines which files should be staged (respecting denylist)
• Generates structured commit message

Phase 2: Commit (--phase2-timeout, default 600s)

• Validates the plan (file existence, denylist compliance)
• Stages approved files, creates commit
• Runs quality gates
• Optionally pushes to remote

Phase 3: Release (--phase3-timeout, default 300s, requires --with-release)

• Analyzes commit history since last tag
• Determines version bump (patch/minor/major)
• Creates git tag and optionally GitHub release

Execution Modes

--execution-mode=agent  # Full AI-driven workflow (default)
--execution-mode=plan   # Phase 1 only: generate plan, stop
--execution-mode=apply  # Phase 2+3: execute existing plan

Preflight Checks

Each repo is validated before spawning an agent:

| Check | Skip Reason | |-------|-------------| | Is git repository | not_a_git_repo | | Git email configured | git_email_not_configured | | Not a shallow clone | shallow_clone | | No rebase in progress | rebase_in_progress | | No merge in progress | merge_in_progress | | Not detached HEAD | detached_HEAD | | Has upstream branch | no_upstream_branch | | Not diverged | diverged_from_upstream |

Security Guardrails

File Denylist - Never committed regardless of agent output:

| Category | Patterns | |----------|----------| | Secrets | .env, .pem, .key, id_rsa*, credentials.json | | Build artifacts | node_modules, __pycache__, dist, build, target | | Logs/temp | .log, .tmp, .swp, .DS_Store | | IDE files | .idea, .vscode, .iml |

Secret Scanning:

--secret-scan=none   # Disable
--secret-scan=warn   # Warn but continue (default)
--secret-scan=block  # Block push on detection

Exit Codes

| Code | Meaning | |------|---------| | 0 | All repos processed successfully | | 1 | Some repos failed (agent error, timeout) | | 2 | Quality gate failures (secrets, tests) | | 3 | System error (ntm, tmux missing) | | 4 | Invalid arguments | | 5 | Interrupted (use --resume) |
