Self-review following DEFAULT_WORKFLOW.md Step 11

Summary

Comprehensive code review identified and fixed 5 critical issues violating project philosophy. All issues have been addressed with zero-BS principle (no stubs, TODOs, or tech debt remaining).

Issues Found and Fixed

1. Code Duplication (CRITICAL)

Violation: Ruthless Simplicity principle Location: src/amplihack/cli.py - Three identical auto mode handling blocks Impact: 40+ lines of duplicated code across launch, claude, and copilot commands

Fix: Extracted handle_auto_mode() helper function

  • Eliminates duplication
  • Single source of truth for auto mode logic
  • Easier to maintain and test

Before: 3 x ~20 lines = 60 lines After: 1 x 25 line helper + 3 x 3 line calls = 34 lines Savings: 26 lines, better maintainability

2. Missing Error Handling (CRITICAL)

Violation: Error Visibility principle Location: auto_mode.py:58, copilot.py:11 Impact: Silent failures on timeout, poor user experience

Fix: Added try/except for TimeoutExpired

try:
    subprocess.run(..., timeout=30)
except subprocess.TimeoutExpired:
    self.log(f"Warning: Hook {hook} timed out")

Result: Visible error messages, graceful degradation

3. Incomplete Implementation (CRITICAL - Zero-BS Violation)

Violation: No stubs or incomplete implementations Location: auto_mode.py:112-114 - Summary generation Impact: Summary was generated but never displayed (stub-like behavior)

Fix: Capture and display summary output

code, summary = self.run_sdk(...)
if code == 0:
    print(summary)
else:
    self.log(f"Warning: Summary generation failed")

Result: Complete implementation, users see summary

4. Hardcoded Path Assumptions (MEDIUM)

Violation: Regeneratable modules principle Location: auto_mode.py - Path.cwd() assumptions Impact: Fails in different execution contexts

Fix: Added working_dir parameter with proper default

def __init__(self, ..., working_dir: Optional[Path] = None):
    self.working_dir = working_dir if working_dir is not None else Path.cwd()

Result: Testable, flexible, works in any context

5. Type Safety Issue (MINOR)

Violation: Code quality standards Location: auto_mode.py:13 - Type annotation Impact: Pyright type checker error

Fix: Proper Optional typing

working_dir: Optional[Path] = None
# And proper None handling
self.working_dir = working_dir if working_dir is not None else Path.cwd()

Result: Type-safe code, passes all checks

Additional Improvements

Better Logging

  • Added exit code logging for errors
  • Better context in warning messages
  • Clearer progression through turns

Enhanced Completion Detection

Before: Simple string matching "COMPLETE" in eval_result After: Multiple signal patterns

if (
    "evaluation: complete" in eval_lower
    or "objective achieved" in eval_lower
    or "all criteria met" in eval_lower
):

Result: More robust completion detection

Documentation Improvements

  • Added pragma comments for unreachable code
  • Better docstrings with Args/Returns
  • Clearer parameter descriptions

Philosophy Compliance Check

✅ Ruthless Simplicity: Code duplication eliminated, minimal abstractions ✅ Zero-BS Principle: No stubs, TODOs, or placeholders ✅ Error Visibility: All errors logged with context ✅ Regeneratable: No hardcoded assumptions, parameterized properly ✅ Present-Moment Focus: Solves actual problems, not hypothetical ones

Code Quality Metrics

Before Review:

  • Duplicated code: 40 lines across 3 functions
  • Type errors: 1 pyright error
  • Silent failures: 2 locations
  • Incomplete implementations: 1 stub-like pattern

After Review:

  • Duplicated code: 0
  • Type errors: 0
  • Silent failures: 0
  • Incomplete implementations: 0

Test Results:

  • ✅ All pre-commit hooks pass
  • ✅ Ruff linting: PASS
  • ✅ Ruff formatting: PASS
  • ✅ Pyright type checking: PASS
  • ✅ Security checks: PASS
  • ✅ CLI help commands work correctly

Security Review

  • ✅ No hardcoded credentials
  • ✅ No injection vulnerabilities (subprocess with list, not shell)
  • ✅ Proper timeout handling
  • ✅ No secrets detected
  • ✅ Secure error messages (no sensitive data leakage)

Review Conclusion

Status: ✅ APPROVED

All critical issues addressed. Code now fully complies with project philosophy:

  • Ruthlessly simple
  • Zero-BS (no stubs or tech debt)
  • Error visibility maintained
  • Type-safe and properly documented
  • Ready for merge

Reviewer Recommendation: This PR is ready to merge after philosophy compliance check (Step 13).
