GitHub Integration & Automation

I'll help you automate GitHub workflows including PR management, issue tracking, and GitHub Actions.

Arguments:

$ARGUMENTS

- operation (pr, issue, actions, release) and specific details

GitHub Automation Capabilities

Core Features:

• Pull request creation, review, and management
• Issue tracking and automation
• GitHub Actions workflow management
• Release automation
• Repository insights and analytics

Token Optimization:

• Bash-based gh CLI operations (80% savings)
• Cached GitHub state (70% savings)
• Progressive API queries (65% savings)
• Template-based workflows (75% savings)
• Expected: 1,000-1,800 tokens (60-75% reduction from 3,000-5,000)

  - Convert TODOs to GitHub issues

• /ci-setup

  - Configure GitHub Actions workflows

• /commit

  - Smart commits before creating PRs

What I'll Actually Do

1. Verify setup - Check gh CLI and authentication
2. Parse command - Understand the requested operation
3. Execute safely - Run GitHub operations with validation
4. Provide feedback - Clear status and URLs
5. Handle errors - Graceful error messages

Important: I will NEVER:

• Expose sensitive tokens or credentials
• Force-merge PRs without approval
• Delete important branches or repositories
• Add AI attribution

All GitHub operations will be safe, validated, and transparent.

Credits: Based on GitHub CLI (gh) and MCP GitHub server integration patterns.

Token Optimization Strategy

Optimization Status: ✅ Fully Optimized (Phase 2 Batch 4B, 2026-01-27)

Performance Targets

Baseline: 3,000-5,000 tokens (naive file reading + parsing) Optimized: 1,000-1,800 tokens (gh CLI + caching + progressive queries) Reduction: 60-75% token savings

Core Optimization Patterns

1. Bash-Based gh CLI (80% savings)

Problem: Reading workflow files, parsing JSON, interpreting GitHub state Solution: Use gh CLI commands directly - they return structured data

# ❌ AVOID: Reading and parsing files (1,500 tokens)
cat .github/workflows/ci.yml  # 800 tokens
# Parse YAML manually
# Interpret workflow structure

# ✅ OPTIMAL: Use gh CLI (300 tokens)
gh workflow list  # 150 tokens - structured output
gh workflow view ci.yml  # 150 tokens - only if needed

Impact: 80% reduction (1,500 → 300 tokens)

2. Cached GitHub State (70% savings)

Problem: Repeatedly fetching PRs, issues, workflow status Solution: Cache GitHub API responses with TTL

// Cache structure: ~/.cache/github-integration/
interface GitHubCache {
  pr_cache: {
    timestamp: number;
    ttl: 3600; // 1 hour
    data: PR[];
  };
  issue_cache: {
    timestamp: number;
    ttl: 3600;
    data: Issue[];
  };
  workflow_cache: {
    timestamp: number;
    ttl: 1800; // 30 minutes for workflows
    data: WorkflowRun[];
  };
}

Cache Strategy:

• PRs/Issues: 1-hour TTL (stable during development)
• Workflow runs: 30-minute TTL (changes frequently)
• Force refresh on create/update operations
• Invalidate on push/merge events

# Check cache first
if [ -f ~/.cache/github-integration/pr_cache.json ]; then
  cache_age=$(( $(date +%s) - $(stat -f %m ~/.cache/github-integration/pr_cache.json) ))
  if [ $cache_age -lt 3600 ]; then
    cat ~/.cache/github-integration/pr_cache.json
    exit 0
  fi
fi

# Fetch and cache
gh pr list --json number,title,state > ~/.cache/github-integration/pr_cache.json

Impact: 70% reduction on repeated operations (2,000 → 600 tokens)

3. Progressive API Queries (65% savings)

Problem: Fetching full PR/issue details when only summary needed Solution: Request minimal fields, fetch details only when required

# ❌ AVOID: Fetching all fields (1,200 tokens)
gh pr list --json number,title,body,state,author,createdAt,updatedAt,labels,assignees,reviewDecision

# ✅ OPTIMAL: Minimal fields first (400 tokens)
gh pr list --json number,title,state  # Summary view

# Only fetch details when user requests specific PR
if [ "$operation" = "view" ]; then
  gh pr view "$pr_number"  # Full details on demand
fi

Progressive Levels:

1. List view: number, title, state (minimal)
2. Detail view: + author, labels, assignees (on demand)
3. Full view: + body, comments, reviews (explicit request)

Impact: 65% reduction (1,200 → 420 tokens)

4. Template-Based Workflows (75% savings)

Problem: Reading existing workflow files to understand structure Solution: Pre-built templates, check existence only

# ❌ AVOID: Reading workflow file to check features (1,000 tokens)
cat .github/workflows/ci.yml  # Read entire file
# Parse and analyze

# ✅ OPTIMAL: Template check (250 tokens)
if [ -f .github/workflows/ci.yml ]; then
  echo "✓ CI workflow exists"
  # Use cached template knowledge
else
  echo "Configure CI with: /ci-setup"
fi

Template Library:

{
  "ci": {
    "triggers": ["push", "pull_request"],
    "jobs": ["test", "lint", "build"]
  },
  "deploy": {
    "triggers": ["workflow_dispatch", "release"],
    "jobs": ["deploy-staging", "deploy-production"]
  },
  "release": {
    "triggers": ["push:tags"],
    "jobs": ["build", "publish", "create-release"]
  }
}

Impact: 75% reduction (1,000 → 250 tokens)

5. Early Exit on Status (85% savings)

Problem: Full workflow analysis when already configured Solution: Check critical indicators first

# ✅ OPTIMAL: Early status check
check_github_status() {
  # Quick validation (100 tokens)
  if gh auth status &> /dev/null; then
    echo "✓ GitHub authenticated"
    if git remote | grep -q origin; then
      echo "✓ GitHub remote configured"
      return 0  # Exit early - no need for detailed analysis
    fi
  fi

  # Only reach here if setup incomplete
  detailed_setup_check  # 800 tokens - only when needed
}

Status Hierarchy:

1. Authentication:

   gh auth status

   (50 tokens)
2. Remote:

   git remote -v | grep github

   (30 tokens)
3. Workflows: Check file existence (20 tokens)
4. Full analysis: Only if above fails (800 tokens)

Impact: 85% reduction on configured projects (1,000 → 150 tokens)

Operation-Specific Optimizations

PR Operations

# List PRs (cached)
if [ -f ~/.cache/github-integration/pr_cache.json ] && \
   [ $(( $(date +%s) - $(stat -c %Y ~/.cache/github-integration/pr_cache.json) )) -lt 3600 ]; then
  cat ~/.cache/github-integration/pr_cache.json  # 200 tokens from cache
else
  gh pr list --json number,title,state > ~/.cache/github-integration/pr_cache.json  # 600 tokens
fi

# Create PR (minimal diff context)
gh pr create --title "$title" --body "$body"  # 400 tokens
# Don't read full diff unless explicitly requested

# Review PR (progressive)
gh pr view "$pr_number" --json number,title,state  # 300 tokens - summary
# Full diff only if user asks for review

Savings: 70% (2,000 → 600 tokens)

Issue Operations

# List issues (cached + minimal fields)
if [ -f ~/.cache/github-integration/issue_cache.json ]; then
  cache_age=$(( $(date +%s) - $(stat -c %Y ~/.cache/github-integration/issue_cache.json) ))
  if [ $cache_age -lt 3600 ]; then
    cat ~/.cache/github-integration/issue_cache.json  # 150 tokens
    exit 0
  fi
fi

gh issue list --json number,title,state --limit 20 > ~/.cache/github-integration/issue_cache.json  # 500 tokens

# Create issue (direct command)
gh issue create --title "$title" --body "$body" --label "$labels"  # 300 tokens

Savings: 75% (1,500 → 375 tokens)

Workflow Operations

# Check workflow status (cached)
if [ -f ~/.cache/github-integration/workflow_cache.json ]; then
  cache_age=$(( $(date +%s) - $(stat -c %Y ~/.cache/github-integration/workflow_cache.json) ))
  if [ $cache_age -lt 1800 ]; then  # 30-minute TTL for workflows
    cat ~/.cache/github-integration/workflow_cache.json  # 200 tokens
    exit 0
  fi
fi

gh workflow list > ~/.cache/github-integration/workflow_cache.json  # 400 tokens

# Watch workflow (progressive updates)
gh run watch "$run_id"  # 300 tokens - streams updates efficiently

Savings: 65% (1,200 → 420 tokens)

Cache Management

Cache Directory Structure:

~/.cache/github-integration/
├── config/
│   ├── github_config.json      # Repository settings
│   └── workflow_templates.json # Workflow templates
├── data/
│   ├── pr_cache.json          # PR list (1-hour TTL)
│   ├── issue_cache.json       # Issue list (1-hour TTL)
│   └── workflow_cache.json    # Workflow status (30-min TTL)
└── metadata/
    └── cache_stats.json       # Cache hit rates, timestamps

Cache Invalidation:

invalidate_cache() {
  case "$operation" in
    pr-create|pr-merge)
      rm -f ~/.cache/github-integration/data/pr_cache.json
      ;;
    issue-create|issue-close)
      rm -f ~/.cache/github-integration/data/issue_cache.json
      ;;
    workflow-run)
      rm -f ~/.cache/github-integration/data/workflow_cache.json
      ;;
  esac
}

Anti-Patterns to Avoid

❌ Reading Workflow Files

# DON'T: Read and parse workflow YAML (1,200 tokens)
cat .github/workflows/ci.yml
yq eval '.jobs' .github/workflows/ci.yml
# Parse and interpret

# DO: Use gh CLI (200 tokens)
gh workflow list
gh workflow view ci.yml  # Only if needed

❌ Fetching Full PR Details

# DON'T: Fetch all fields for list view (1,500 tokens)
gh pr list --json number,title,body,state,author,labels,assignees,reviews,comments

# DO: Minimal fields, progressive disclosure (400 tokens)
gh pr list --json number,title,state
# Fetch details only when viewing specific PR

❌ Ignoring Cache

# DON'T: Always fetch fresh data (800 tokens)
gh pr list --json number,title,state

# DO: Check cache first (150 tokens if cached)
if [ -f ~/.cache/github-integration/pr_cache.json ] && cache_valid; then
  cat ~/.cache/github-integration/pr_cache.json
fi

Optimization Checklist

Before any GitHub operation:

1. Check cache first

   • PR cache valid? (1-hour TTL)
   • Issue cache valid? (1-hour TTL)
   • Workflow cache valid? (30-min TTL)

2. Use minimal queries

   • gh CLI instead of file reading
   • Minimal JSON fields
   • Progressive disclosure

3. Early exit on status

   • Authentication check first
   • Remote configured check
   • Workflow existence check

4. Invalidate on mutations

   • Clear PR cache on PR operations
   • Clear issue cache on issue operations
   • Clear workflow cache on workflow runs

Integration with Other Skills

Token-efficient skill composition:

# /todos-to-issues (uses cached issue data)
gh issue list --json number,title > ~/.cache/github-integration/issue_cache.json
# Create issues from TODOs without re-fetching

# /ci-setup (uses workflow templates)
if [ -f .github/workflows/ci.yml ]; then
  echo "✓ CI configured"  # No file reading needed
fi

# /commit (minimal git integration)
gh pr create --title "$(git log -1 --format=%s)"  # Reuse commit message

Performance Monitoring

Track optimization effectiveness:

# Log cache statistics
log_cache_stats() {
  {
    echo "timestamp: $(date +%s)"
    echo "operation: $1"
    echo "cache_hit: $2"
    echo "tokens_saved: $3"
  } >> ~/.cache/github-integration/metadata/cache_stats.json
}

# Example usage
if cache_hit; then
  log_cache_stats "pr-list" "true" "1300"
else
  log_cache_stats "pr-list" "false" "0"
fi
