Claude Code GitHub Actions Automation: A Practical Guide to Generating Code at 6 AM

Target Audience

  • Beginners who want to automatically run Claude Code tasks at a scheduled time every morning

Key Points

  1. Set up automated GitHub Actions execution at 6 AM
  2. Understand the basics of Claude Code workflows
  3. Build a sustainable daily automation system

The Core Problem

By using GitHub Actions scheduled triggers instead of cron jobs, you can build a more stable and manageable periodic execution environment. The key advantages are zero server maintenance costs and easy-to-access logs.

Solution

Step 1: Create Workflow File

Create .github/workflows/morning-automation.yml and configure it to run every morning at 6 AM.

name: Morning Claude Code Automation
on:
  schedule:
    - cron: '0 21 * * *'  # UTC 21:00 = JST 06:00
jobs:
  run-analysis:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Run morning tasks
        run: python main.py

Step 2: Configure Execution Permissions

Go to repository Settings > Actions > General, select "Allow all actions," and enable scheduled workflows.

# Verify Actions are enabled in the repository
gh repo view --json defaultBranchRef

Step 3: Verify Operation

Test the workflow with a manual trigger to confirm it works properly before starting scheduled execution.

on:
  schedule:
    - cron: '0 21 * * *'
  workflow_dispatch:  # For manual execution

# Execute only on weekdays (Monday–Friday)
- cron: '0 21 * * 1-5'

# Execute every hour
- cron: '0 * * * *'

# Execute once a week (Sunday)
- cron: '0 21 * * 0'
In actual production environments, it's important to adjust execution frequency according to project scale.
