Advanced Patterns

Cursor: Context Chaining

Combine multiple @ references for comprehensive context:

@UserAuth @DatabaseSchema @recent-changes
explain how authentication works with the database

@src/api/*.js @tests/*.test.js
ensure all API endpoints have corresponding tests

Claude Code: Piping and Automation

# Analyze logs
tail -f app.log | claude -p "monitor for errors"

# Automated code review
git diff | claude -p "review these changes for bugs"

# CI/CD integration
claude -p "fix linting errors" --dangerously-skip-permissions

# JSON output for scripts
claude -p "list all TODO comments" --output-format json

# Scheduled tasks
0 * * * * claude -p "generate status report" > report.md

Codex: Automation Patterns

# GitHub issue automation
# (configured through Codex App settings)
# Assign issue to @codex to trigger cloud agent

# Local interactive
codex "implement the feature described in issue #42"

# Full auto with sandbox
codex --full-auto "add input validation to all API endpoints"

# Quick review
codex "what would break if I remove this function?"
