Claude Code Automation Workflows

GitHub Actions Integration

Integrating Claude Code into CI/CD enables automated code review, fixes, and documentation.

Typical Use Cases

• PR review: Call Claude on PR changes; post results as comments
• Auto-fix: On lint or test failures, use Claude to suggest or apply fixes
• Doc sync: After merge, trigger Claude to update docs or CHANGELOG from code changes

Configuration

• Secrets: Store ANTHROPIC_API_KEY in GitHub Secrets
• Triggers: pull_request, push, workflow_dispatch, etc.
• Context: Pass code via checkout, paths, etc.
• Output: Use gh pr comment, gh issue comment, or artifacts.

Cost and Rate Limits

• Limit token usage per run to avoid overruns
• For large PRs, sample or chunk
• Set timeouts and retry policies

Hooks Integration

Git hooks can integrate Claude at key points in the workflow.

Pre-commit

• In pre-commit, call Claude for style checks or simple refactoring suggestions
• On issues, auto-fix and re-add, or prompt the user
• Keep execution time short to avoid blocking commits

Post-merge / Post-checkout

• After merge or checkout, sync docs, update dependency notes
• Can run asynchronously to avoid blocking main flow

Custom Hooks

• Use prepare-commit-msg with Claude to generate commit messages
• Use pre-push for final tests and checks

Implementation

• Use husky, lefthook, etc. to manage hooks
• In scripts, call Claude API or claude CLI with diff, file list, etc.

Batch Processing

For large numbers of files or tasks:

Task Splitting

• Each task is independent and retryable; avoid single-point failure
• Support checkpoint resume; record completed task IDs

Concurrency Control

• Respect API rate limits when setting concurrency
• Use queues (e.g., Redis, in-memory) for pending tasks

Result Collection

• Write per-task results to files or a database
• Distinguish success, failure, skip for stats and retries
• Support manual or automatic retry for failures

Example Flow

Scan pending list (e.g., files to translate)

Generate task description and context per item

Call Claude for each; save results

Aggregate report; flag anomalies

Summary

Claude Code automation via GitHub Actions, Hooks, and batch processing embeds AI into the development pipeline. Designing triggers, context passing, and result feedback well can significantly improve code quality and developer velocity.
