Prash by Drufiy — Backend
Your CI never breaks twice.
Prash is an autonomous CI/CD repair agent for GitHub Actions. It receives failed workflow events, retrieves and analyses logs, classifies repair risk, creates corrective pull requests when appropriate, and verifies the result against subsequent CI runs.
This repository contains the backend services and agent workflow.
How it works
- A connected repository sends a signed
workflow_run webhook.
- Prash retrieves the relevant GitHub Actions logs.
- The diagnosis agent identifies the failure, root cause, repair category, confidence, and proposed file changes.
- Safety checks compare proposed changes with known-good workflow files.
- Eligible repairs are committed to a dedicated branch and opened as pull requests.
- Prash watches every workflow associated with the repair commit.
- A passing result is marked verified; a failed attempt can trigger a second diagnosis using the new evidence.
Architecture
- API: FastAPI and Python
- Database: Supabase/PostgreSQL
- Realtime events: Supabase Realtime
- Authentication: GitHub OAuth with JWT sessions
- Repository integration: GitHub REST API and signed webhooks
- AI workflow: Structured model output with fallback handling
- Deployment target: Containerised cloud runtime

Documentation
Status
Prash is in early access and is being developed with design-partner feedback. Automated repairs should be tested in controlled repositories before production adoption.
Founders
Prash is being built at Drufiy by Aradhya Mishra and Maneesh Awasthi.
