Autonomous coding workflow ships 163K lines overnight using Claude Code
A developer on r/ClaudeAI shared results from an autonomous coding workflow they built over a weekend. The system was designed to build a GTM tool that started as 40 internal features and expanded to 144 tasks across services, APIs, UI pages, and cron jobs.
Workflow process
The autonomous pipeline operates without human intervention:
- Picks a pending task
- Reads the PRD (Product Requirements Document)
- Runs a pre-check agent
- Implements code and writes tests
- Validates against acceptance criteria
- Retries on failure
- Includes custom steps for self-healing
- Moves to next task automatically
Overnight results
The developer started the workflow at 3:15 AM and checked results 14 hours later:
- 72 tasks completed
- 163,643 lines of code generated
- 6,400+ tests passing
- 85% first-attempt success rate
- 0 tasks failed
- 458 source files created
- 84 test files created
- Workflow was still running when checked
The developer estimates this would have taken 2-3 months of full-time solo development work if done manually. They're currently cleaning up the workflow, adding a GUI, and plan to ship it as a free tool.
