WalkthroughThis PR removes the LLM integration layer, hardware profiler, and sandbox executor modules—along with their tests and demo scripts—and introduces a focused SystemRequirementsChecker for pre-flight system validation. The codebase is simplified from ~1000+ lines to ~257 lines, concentrating on disk space, RAM, OS, architecture, packages, and GPU detection before installation. Changes

🧹 Nitpick comments (5)
src/requirements.txt (1)
9-12: Remove pytest-asyncio (not needed for synchronous tests).The
pytest-asynciodependency is listed, but there is no async code in the requirements checker implementation. This dependency is unnecessary.Apply this diff:
# Testing Dependencies (dev) pytest>=7.0.0 -pytest-asyncio>=0.21.0 pytest-cov>=4.0.0src/requirements_checker.py (3)
1-1: Make script executable or remove shebang.The shebang is present but the file is not marked as executable.
Run this command to make the file executable:
chmod +x src/requirements_checker.py
121-130: MEMORYSTATUSEX structure definition inside method.Defining the
MEMORYSTATUSEXctypes structure inside the method works but is unconventional. If this method is called repeatedly, the structure is redefined each time.Consider moving the structure definition to module level or caching it:
# At module level (after imports) if os.name == 'nt': import ctypes class MEMORYSTATUSEX(ctypes.Structure): _fields_ = [ ("dwLength", ctypes.c_ulong), ("dwMemoryLoad", ctypes.c_ulong), ("ullTotalPhys", ctypes.c_ulonglong), ("ullAvailPhys", ctypes.c_ulonglong), ("ullTotalPageFile", ctypes.c_ulonglong), ("ullAvailPageFile", ctypes.c_ulonglong), ("ullTotalVirtual", ctypes.c_ulonglong), ("ullAvailVirtual", ctypes.c_ulonglong), ("sullAvailExtendedVirtual", ctypes.c_ulonglong) ]
243-254: Add error handling for unexpected exceptions in main.The main function should handle unexpected exceptions gracefully to provide better user experience.
Apply this diff:
def main(): - import argparse - parser = argparse.ArgumentParser(description='Check system requirements') - parser.add_argument('package', help='Package name') - parser.add_argument('--force', action='store_true', help='Force installation despite warnings') - parser.add_argument('--json', action='store_true', help='JSON output') - args = parser.parse_args() - - checker = SystemRequirementsChecker(force_mode=args.force, json_output=args.json) - success = checker.check_all(args.package) - checker.print_results() - sys.exit(0 if success else 1) + try: + import argparse + parser = argparse.ArgumentParser(description='Check system requirements') + parser.add_argument('package', help='Package name') + parser.add_argument('--force', action='store_true', help='Force installation despite warnings') + parser.add_argument('--json', action='store_true', help='JSON output') + args = parser.parse_args() + + checker = SystemRequirementsChecker(force_mode=args.force, json_output=args.json) + success = checker.check_all(args.package) + checker.print_results() + sys.exit(0 if success else 1) + except KeyboardInterrupt: + sys.exit(130) + except Exception as e: + print(f"Unexpected error: {e}", file=sys.stderr) + sys.exit(2)README_MINIMAL.md (1)
1-31: README duplication between README.md and README_MINIMAL.md.The content of
README_MINIMAL.mdis nearly identical toREADME.md. Consider consolidating into a single README file unless there's a specific reason to maintain separate documentation.

31-44: Clean dataclass design.The
RequirementCheckdataclass with custom__str__method provides a clear and well-structured representation of check results.
47-62: Correct handling of mutable defaults.The use of
Noneas default values with initialization in__post_init__is the proper pattern to avoid shared mutable default issues in dataclasses.
162-168: Architecture check is clean and straightforward.
198-207: Linux distribution detection follows standard practice.Reading
/etc/os-releaseis the modern, standardized way to detect Linux distributions.
209-225: Check aggregation logic is well-structured.The
check_allmethod cleanly orchestrates all validation checks and properly implements force mode to override errors.
227-240: Output formatting supports both JSON and human-readable formats appropriately.

Critical inconsistency: PR description contradicts this summary.
This summary states that test files, example files, and documentation files were removed, claiming a reduction from 1,053 lines to 244 lines. However, the PR description explicitly states:
- "Tests included: 47 tests, 100% passing"
- "src/requirements_checker.py (650 lines)"
- "src/test_requirements_checker.py (380 lines, 47 tests)"
- "docs/REQUIREMENTS_CHECKER.md"
- "examples/requirements_demo.py"
These claims are fundamentally incompatible. Either:
- This is a simplification PR that removes tests/docs (as this file states), OR
- This is a feature addition PR with comprehensive tests/docs (as PR description claims)
The actual files under review show no test file, no docs folder, and only 259 lines in requirements_checker.py—not 650 lines as claimed.
🤖 Prompt for AI Agents
In SIMPLIFICATION_SUMMARY.md around lines 1 to 39, the summary contradicts the
PR description by claiming tests/docs were removed and showing a 1,053→244 lines
reduction while the PR description lists tests, docs, and different file sizes;
resolve this by reconciling the two sources: verify the repository contents and
then update this summary to accurately reflect the actual changes (either
restore the tests/docs and update file lists and line counts to match the PR
description, or edit the PR description to reflect the simplification), correct
the reported file names and exact line counts for src/requirements_checker.py
and any remaining files, remove any false claims about removed/added files
(tests/examples/docs), and update the totals and bullet lists so every item and
metric matches the repository state and PR text.

Critical code duplication: identical to requirements_checker.py.
The file src/requirements_checker_minimal.py appears to be a complete duplicate of src/requirements_checker.py. Both files are 259 lines and contain identical code, which violates the DRY (Don't Repeat Yourself) principle and creates maintenance burden.
Verify the files are identical and remove the duplicate:
#!/bin/bash
# Check if files are identical
diff src/requirements_checker.py src/requirements_checker_minimal.py
if [ $? -eq 0 ]; then
echo "Files are identical - one should be removed"
else
echo "Files differ - minimal version should be significantly smaller"
fiIf the files are truly identical, remove one of them. If a "minimal" version is genuinely needed, it should be substantially different (e.g., removing optional features, simplifying output, reducing dependencies).

Hardcoded Windows drive path.
The code assumes C:\ is the system drive on Windows, but this may not always be true. Some systems use different drive letters for the OS installation.
Consider detecting the system drive programmatically:
if os.name == 'nt':
import ctypes
free_bytes = ctypes.c_ulonglong(0)
+ # Get the system drive (usually C:\ but not always)
+ system_drive = os.environ.get('SystemDrive', 'C:') + '\\'

- ctypes.c_wchar_p('C:\\'), None, None, ctypes.pointer(free_bytes)
+ ctypes.c_wchar_p(system_drive), None, None, ctypes.pointer(free_bytes)

hardcodes 'C:\\'—detect the system drive instead: determine the system drive by
first checking os.environ.get('SYSTEMDRIVE'), and if that's missing use the

GetWindowsDirectory/GetSystemDirectory via ctypes) and extract its drive letter;
build a proper path like 'X:\\' and pass that to GetDiskFreeSpaceExW; fall back
to 'C:\\' only if detection fails and ensure the chosen path is provided as a

Fragile parsing of df output.
The parsing logic assumes a specific df output format and uses hardcoded array index [3] for available space. This can break if:
- The filesystem path contains spaces
- Different
dfversions produce different output formats - Localized output formats differ
Consider using a more robust approach:
- result = subprocess.run(['df', '-BG', '/'], capture_output=True, text=True, timeout=5)
- if result.returncode == 0:
- parts = result.stdout.strip().split('\n')[1].split()
- available_gb = float(parts[3].replace('G', ''))
- else:
- available_gb = 0
+ result = subprocess.run(['df', '--output=avail', '-BG', '/'],

+ if result.returncode == 0:

+ if len(lines) >= 2:
+ available_gb = float(lines[1].replace('G', ''))
+ else:
+ available_gb = 0
+ else:
+ available_gb = 0Note: --output=avail ensures only the available space column is returned, making parsing more reliable.

Package detection using shutil.which has limitations.
Using shutil.which() only checks if an executable is in PATH, not whether the package is properly installed via the system package manager. For example, libaio1 is a library package without an executable, so shutil.which('libaio1') will always fail even if the package is installed.
For Linux systems, consider querying the package manager:
def check_packages(self, required_packages: List[str]) -> RequirementCheck:
missing = []
for pkg in required_packages:
# Try executable check first
if shutil.which(pkg):
continue
# For library packages on Linux, check package manager
if platform.system().lower() == 'linux':
# Try dpkg (Debian/Ubuntu)
result = subprocess.run(['dpkg', '-l', pkg],
capture_output=True, timeout=2)
if result.returncode == 0:
continue
# Try rpm (RHEL/Fedora/CentOS)
result = subprocess.run(['rpm', '-q', pkg],

In src/requirements_checker.py around lines 170 to 181, the current package
check uses shutil.which which only detects executables and misses library/system
packages (e.g., libaio1); update the implementation to first try
shutil.which(pkg) and if that fails and platform.system().lower() == 'linux'
query common package managers: run dpkg -l pkg and if that fails run rpm -q pkg
using subprocess.run with capture_output=True and a short timeout, treat
returncode==0 as “installed” and continue, add proper exception handling for
subprocess timeouts or OSErrors (treat as not found), append truly missing
packages to missing, and ensure subprocess and platform are imported; keep the
same RequirementCheck return behavior.

Same bug: CheckStatus.INFO does not exist.
Lines 194 and 196 use CheckStatus.INFO, which is not defined in the enum. This will cause runtime errors.
Apply the same fix as suggested for the check_os method—either add INFO to the enum or use WARNING instead.
