Advanced automation patterns and multi-step processes
314+
315+
### Automated Code Review Workflows
316+
317+
```bash
318+
# Automated PR review process
319+
#!/bin/bash
320+
git diff HEAD~1 | claude -p "review this PR for security issues" > security_review.md
321+
git diff HEAD~1 | claude -p "check for performance issues" > performance_review.md
322+
git diff HEAD~1 | claude -p "suggest improvements" > improvements.md
323+
```
324+
325+
### Continuous Integration Integration
326+
327+
```bash
328+
# CI/CD pipeline integration
329+
claude -p "analyze test coverage" --output-format json | jq '.coverage_percentage'
330+
claude -p "generate release notes from commits" --max-turns 2 > RELEASE_NOTES.md
331+
```
332+
333+
### Batch Processing Workflows
334+
335+
```bash
336+
# Process multiple files
337+
find . -name "*.js" -exec claude -p "analyze this file for bugs: {}" \; > bug_report.txt
338+
339+
# Automated documentation generation
340+
for file in src/*.py; do
341+
claude -p "generate docstring for $file" --output-format text >> docs.md

/cos # Check current session costs
400+
/doctor --performance # Performance diagnostics
401+
```
402+
403+
### Caching & Optimization
404+
405+
```bash
406+
# Efficient session reuse
407+
claude -c "continue previous analysis" # Reuse existing context
408+
claude --cache-results "repetitive task" # Cache common operations
409+
410+
# Parallel processing
411+
claude -p "task 1" & claude -p "task 2" & wait # Parallel execution
412+
```
413+
414+
### Large-Scale Processing
415+
416+
```bash
417+
# Handle large codebases efficiently
