Overview

ITERUN is a system that allows you to:

1. Define intents using a simple YAML-based DSL
2. Simulate execution with dry-run planning
3. Get AI suggestions using local LLMs via Ollama
4. Iteratively refine your intent through feedback loops
5. Execute safely with the ITERUN boundary (explicit approval required)

Workflow

1. Define Intent → Write DSL or use web editor
2. Parse → Convert DSL to IR (Intermediate Representation)
3. Plan → Run dry-run simulation, review generated code
4. Get AI Suggestions → Analyze with local LLM
5. Iterate → Make changes, re-plan until satisfied
6. Execute → Run with auto-validation and auto-fix
7. Validate → Automatic health checks on all endpoints

Validation & Auto-Fix

After container deployment, the system automatically:

1. Waits for container startup (configurable STARTUP_WAIT)
2. Validates all exposed endpoints with HTTP requests
3. Detects issues like connection refused, timeouts, HTTP errors
4. Auto-fixes common problems:
   • Missing __main__ block
   • Wrong port configuration
   • Missing dependencies
5. Restarts container with fixes
6. Re-validates until success or max iterations reached

Configuration

# In .env
VALIDATE_AFTER_EXECUTE=true
AUTO_FIX_ENABLED=true
MAX_FIX_ITERATIONS=3
STARTUP_WAIT=2
VALIDATION_TIMEOUT=10
