Self-Healing Loops

Automatic fixing of build, test, and lint failures without manual intervention

Problem Solved: Manual Failure Fixing

❌ Without Self-Healing

  • ✗ Build fails → manually investigate
  • ✗ Tests fail → manually debug
  • ✗ Lint errors → manually fix
  • ✗ Context switching between failures
  • ✗ Time wasted on routine fixes

✓ With Self-Healing

  • ✓ Automatic failure detection
  • ✓ AI analyzes root cause
  • ✓ Applies fixes automatically
  • ✓ Re-runs to validate
  • ✓ Continuous until success

How Self-Healing Works

1

Detect Failure

Build, test, or lint fails

System monitors all execution results

2

Analyze Root Cause

AI examines error messages and context

Understands what went wrong and why

3

Apply Fix

AI implements the solution

Modifies code, dependencies, or configuration

4

Validate

Re-run to check success

If still failing, loop continues

5

Success

Build passes, tests green

Move on to next task automatically

The /siftcoder:heal Command

/siftcoder:heal

Automatically detects and fixes the most recent build, test, or lint failure

Build Failures

  • TypeScript compilation errors
  • Missing dependencies
  • Import/export issues
  • Configuration problems
  • Syntax errors

Test Failures

  • Assertion failures
  • Mock configuration issues
  • Test environment problems
  • Async timing issues
  • Fixture setup errors

Lint Errors

  • Code style violations
  • Unused imports/variables
  • Complexity warnings
  • Best practice violations
  • Type safety issues

Runtime Errors

  • Null reference errors
  • Undefined properties
  • Promise rejection issues
  • API integration problems
  • Edge case bugs

Real-World Healing Examples

TypeScript Compilation Error

BEFORE

Error: Type 'string' is not assignable to type 'number' at src/utils/calculate.ts:15:3

AFTER

✓ Added type coercion: Number(input) ✓ Re-compiled: 0 errors ✓ All tests passing Time to fix: 8 seconds
Time to fix: 8 seconds

Missing Dependency

BEFORE

Error: Cannot find module 'zod' Require stack: src/validation/schema.ts

AFTER

✓ Installed zod@latest ✓ Updated package.json ✓ Re-ran build: Success ✓ Verified imports: OK Time to fix: 12 seconds
Time to fix: 12 seconds

Test Assertion Failure

BEFORE

FAIL src/auth/login.test.ts Expected: 200 Received: 401 Missing authentication header

AFTER

✓ Added auth header to test setup ✓ Updated test fixture ✓ Re-ran tests: 47/47 passing ✓ Verified no regressions Time to fix: 15 seconds
Time to fix: 15 seconds

Lint Violations

BEFORE

Warning: Unused variable 'temp' Warning: Missing return type Warning: Complex function (cyclomatic complexity: 12) 26 lint errors found

AFTER

✓ Removed unused variables ✓ Added explicit return types ✓ Refactored complex function ✓ Re-ran lint: 0 errors Time to fix: 22 seconds
Time to fix: 22 seconds

Key Benefits

Zero Manual Intervention

Fixes happen automatically without you lifting a finger

Continuous Quality

Codebase stays healthy automatically

Massive Time Savings

What takes minutes manually happens in seconds

Learning System

Gets smarter about your codebase over time

When Self-Healing Activates

Automatic Triggers

  • After any code change: Runs build, test, and lint automatically
  • On failure detection: Immediately starts healing loop
  • Until success: Continues trying different approaches
  • Manual invocation: Run /siftcoder:heal anytime

Comparison: Manual vs Self-Healing

TypeScript error

Manual

3-5 minutes reading docs, fixing, rebuilding

Auto

8-15 seconds automatic fix

Improvement

20-40x faster

Missing dependency

Manual

5-10 minutes finding right package version

Auto

10-20 seconds auto-install

Improvement

30-50x faster

Test failure

Manual

10-20 minutes debugging test

Auto

15-30 seconds fix and validate

Improvement

40-80x faster

Lint errors

Manual

5-15 minutes fixing each error

Auto

20-40 seconds batch fix

Improvement

15-45x faster

Average Time Saved: 95%

Tasks that take 5-20 minutes manually are completed in 10-40 seconds automatically. Over a typical workday, self-healing loops save 2-4 hours of routine fixing time.
