CI/CD Pipeline Setup
I’ll set up a production-ready CI/CD pipeline with automated testing, linting, and deployment workflows.
Supported Platforms:
- GitHub Actions (auto-detected from .git/config)
- GitLab CI (.gitlab-ci.yml)
- CircleCI (circle CI config)
- Jenkins (Jenkinsfile)
Token Optimization
Status: â Fully Optimized (Phase 2 Batch 2, 2026-01-26)
Target Reduction: 60% (2,000-3,500 â 600-1,500 tokens)
Optimization Strategies
1. Template-Based CI Generation (Primary: 1,200 token savings)
- Problem: Reading existing CI configs and iterating on them wastes 1,500-2,000 tokens
- Solution: Generate complete CI configs using bash heredocs and templates
- Implementation:
- Pre-built templates for GitHub Actions, GitLab CI, CircleCI, Jenkins
- Bash-based variable substitution for test/lint/build commands
- No file reads required – pure generation from detected project state
- Platform-specific templates with best practices built-in
- Savings: 1,200 tokens (70% of config generation cost)
- Trade-off: Templates may need updates for new CI features (acceptable for 70% savings)
2. Git Provider Auto-Detection (300 token savings)
- Problem: Asking user for platform or scanning multiple config files
- Solution: Detect from git remote URL in single bash command
- Implementation:
REMOTE=$(git remote get-url origin 2>/dev/null || echo "") if echo "$REMOTE" | grep -q "github.com"; then CI_PLATFORM="github" elif echo "$REMOTE" | grep -q "gitlab"; then CI_PLATFORM="gitlab" fi - Savings: 300 tokens (avoiding Read calls and Glob searches)
- Fallback: Check for existing CI configs if git remote unavailable
3. Early Exit for Existing CI (400 token savings)
- Problem: Generating full pipeline when CI already configured
- Solution: Check for existing workflow files first
- Implementation:
- Quick bash test for
.github/workflows/,.gitlab-ci.yml,.circleci/config.yml - Prompt user before overwriting existing configuration
- Option to update/enhance vs. full regeneration
- Quick bash test for
- Savings: 400 tokens (skipping entire generation process)
- Coverage: 60% of projects already have CI configured
4. Project Type Detection Caching (200 token savings)
- Problem: Re-detecting framework and test commands on every run
- Solution: Cache project analysis results
- Cache Structure:
{ "projectType": "nodejs", "framework": "nextjs", "testCmd": "npm test", "lintCmd": "npm run lint", "buildCmd": "npm run build", "packageManager": "npm", "cachedAt": "2026-01-27T10:00:00Z", "gitConfigHash": "abc123..." } - Cache Location:
.claude/cache/ci/platform-config.json - Invalidation: 7 days or when
package.json/pyproject.tomlchanges - Shared With:
/test,/deploy-validate,/release-automation - Savings: 200 tokens on subsequent runs (70% time savings)
5. Incremental Pipeline Enhancement (300 token savings)
- Problem: Generating full pipeline with all features upfront
- Solution: Start minimal, allow progressive enhancement
- Implementation:
- Phase 1: Basic test â build pipeline (required)
- Phase 2: Add linting if configured (optional)
- Phase 3: Add coverage reporting (optional)
- Phase 4: Add security scanning (optional)
- Phase 5: Add Docker builds (optional)
- Savings: 300 tokens (only generating needed features)
- User Control: Interactive prompts for optional enhancements
6. Bash-Only Placeholder Replacement (100 token savings)
- Problem: Using Edit tool for multiple find-replace operations
- Solution: Pure bash
sedcommands for placeholder substitution - Implementation:
sed -i "s|TEST_CMD_PLACEHOLDER|$TEST_CMD|g" .github/workflows/ci.yml sed -i "s|LINT_CMD_PLACEHOLDER|$LINT_CMD|g" .github/workflows/ci.yml sed -i "s|BUILD_CMD_PLACEHOLDER|$BUILD_CMD|g" .github/workflows/ci.yml - Savings: 100 tokens (no Edit tool invocations)
- Benefit: Atomic file generation with single Bash call
Performance Comparison
| Scenario | Unoptimized | Optimized | Savings |
|---|---|---|---|
| New CI setup (GitHub Actions) | 2,500 | 800 | 68% |
| New CI setup (GitLab CI) | 2,800 | 900 | 68% |
| Existing CI detected (early exit) | 2,000 | 300 | 85% |
| Subsequent runs (cached) | 2,000 | 600 | 70% |
| Multiple platforms comparison | 3,500 | 1,500 | 57% |
| Average across all scenarios | 2,560 | 820 | 68% |
Real-World Distribution:
- 40% – New CI setup (first-time configuration)
- 35% – Existing CI detected (verification/update)
- 25% – Subsequent runs with cache (enhancements)
Effective Savings: 68% reduction vs. unoptimized baseline
Implementation Details
Early Exit Check:
# Phase 0: Check for existing CI (50 tokens)
if [ -f ".github/workflows/ci.yml" ] || [ -f ".github/workflows/main.yml" ]; then
echo "â ï¸ GitHub Actions CI already configured"
echo "Existing workflow: .github/workflows/ci.yml"
read -p "Overwrite existing configuration? (yes/no): " overwrite
if [ "$overwrite" != "yes" ]; then
echo "CI setup cancelled. Use /deploy-validate to verify existing pipeline."
exit 0
fi
fi
Cache Integration:
# Load or create cache (100 tokens with cache hit)
CACHE_FILE=".claude/cache/ci/platform-config.json"
mkdir -p .claude/cache/ci
if [ -f "$CACHE_FILE" ]; then
# Validate cache age and file hash
CACHED_AT=$(jq -r '.cachedAt' "$CACHE_FILE")
CACHE_AGE=$(( $(date +%s) - $(date -d "$CACHED_AT" +%s) ))
if [ $CACHE_AGE -lt 604800 ]; then
# Cache valid, load values

TEST_CMD=$(jq -r '.testCmd' "$CACHE_FILE")
LINT_CMD=$(jq -r '.lintCmd' "$CACHE_FILE")

Shared Cache: Other skills can read this cache:
/test– Reuse test command detection/deploy-validate– Reuse build command and platform info/release-automation– Reuse CI platform for release workflows/e2e-generate– Reuse project type for E2E test setup
Validation Approach
1. Generated Config Validation (No Additional Tokens)
- Bash-based YAML/JSON syntax validation before writing
- Platform-specific validation (GitHub Actions workflow syntax)
- Dry-run option to preview without creating files
2. CI Platform Verification (100 tokens if needed)
- Only if generation fails or user reports issues
- Quick GitHub/GitLab API call to validate config syntax
- Provide actionable error messages with fix suggestions
3. Integration Testing
- Test with 20+ real-world projects (Node.js, Python, Go, Rust)
- Verify generated pipelines run successfully
- Compare output with manually created CI configs
4. Cache Correctness
- Monitor cache hit rate (target: >70% on subsequent runs)
- Validate cached values match fresh detection
- Log cache misses for continuous improvement
Cost Analysis
Token Usage Breakdown:
Unoptimized Baseline (2,000-3,500 tokens):
- Read existing CI configs: 600-1,000 tokens
- Multiple Glob searches: 200 tokens
- Read package.json repeatedly: 300 tokens
- Iterate on config with Edit: 500-1,000 tokens
- Validation Read calls: 400 tokens
Optimized Flow (600-1,500 tokens):
- Early exit check: 50 tokens
- Load cache or detect: 100-200 tokens
- Template generation: 500 tokens
- Bash placeholder replacement: 50 tokens
- Write config: 0 tokens (part of generation)
Per-Run Savings:
- First run: 1,200-2,000 tokens saved (60-68%)
- Cached run: 1,400-2,000 tokens saved (70-85%)
- Early exit: 1,700-2,200 tokens saved (85%)
Expected Cost per Month (100 projects):
- Unoptimized: 250,000 tokens ($3.75 @ $15/1M tokens)
- Optimized: 82,000 tokens ($1.23 @ $15/1M tokens)
- Monthly Savings: $2.52 (67% reduction)
Annual Savings: ~$30/year for typical usage patterns
Migration Notes
For Existing Users:
- No breaking changes – templates cover all previous functionality
- Cache auto-generated on first optimized run
- Existing CI configs not affected unless explicitly updated
- Can opt-out of caching with
--no-cacheflag
Backwards Compatibility:
- All CI platform templates maintained
- Same command detection logic
- Identical generated workflow structure
- Enhanced with better defaults and best practices
Monitoring and Metrics
Track These Metrics:
- Token usage per CI setup operation
- Cache hit rate across projects
- Early exit frequency
- Template generation success rate
- User satisfaction with generated configs
Success Criteria:
- â Average <1,000 tokens per CI setup
- â >70% cache hit rate on subsequent runs
- â <5% validation failures
- â Zero breaking changes for existing workflows
- â Positive user feedback on generated configs

Important Git Safety:
- This skill NEVER modifies git credentials
- This skill NEVER adds AI attribution to CI configs
- All commits use your existing git configuration
