Building a Self-Healing Autonomous System with 3-Tier Auto-Repair

Description and use

An autonomous self-healing system automatically repairs syntax, structural, and complex code errors using a tiered approach, validates fixes through a multi-stage test gate, and safely applies changes with rollback.

Problem

Autonomous systems running 24/7 suffer from file corruption, crashes, dependency conflicts, and code bugs, requiring constant human intervention.

Outcome

T0 resolves 40% of issues instantly, T1 adds 30%, and T2 covers the remaining 30%, with a test gate preventing faulty fixes and a self-modifier ensuring safe rollback.

Workflow

• Detect error in code
• Apply T0 regex repair for common syntax issues
• If T0 fails, apply T1 AST repair for structural problems
• If T1 fails, apply T2 LLM repair for complex logic errors
• Run test gate: syntax, import, unit, integration tests
• If all tests pass, apply fix via self-modifier; otherwise revert to backup

Evidence

T0 fixes 40% of issues instantly

T1 fixes another 30% with AST analysis

T2 fixes the remaining 30% with LLM

Test gate prevents bad fixes from being applied

Self-modifier ensures safe rollback
