If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/lucasg/Dependencies shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

Dependencies is a modern C# rewrite of the legacy Dependency Walker (depends.exe), a Windows developer tool that analyzes and visualizes DLL load dependencies, imports, exports, and API set requirements for executables and libraries. It provides both a CLI tool (Dependencies.exe) and GUI (DependenciesGui.exe) to troubleshoot missing or incompatible DLL dependencies, symbol resolution issues, and manifest/SxS conflicts. Monorepo structure: ClrPhlib/ contains a mixed-mode C++/CLI wrapper (managed+ unmanaged PE parsing, symbol providers, ApiSet handling), Dependencies/ is the CLI console app entry point, and DependenciesGui/ is the WPF GUI frontend. Core logic lives in ClrPhlib/src/ with separate managed (NativeFile.cpp, PE.cpp, PeImport.cpp, PeExport.cpp) and unmanaged (UnmanagedPE.cpp, UnmanagedSymPrv.cpp) layers.

Windows systems programmers and application developers who need to diagnose why their EXE/DLL fails to load due to missing dependencies, circular references, architecture mismatches (x86/x64), or API set incompatibilities. Also useful for security researchers analyzing binary dependencies and reverse engineers examining export tables.

Actively maintained and production-ready. The project has reached v1.11.1, includes CI/CD via AppVeyor, and shows continuous incremental improvements (recent additions: Windows 8.1 API set parsing, LLVM demangler support, CLR assembly enumeration). However, it is a single-maintainer project (lucasg) with no visible test suite in the file structure.

Single maintainer (lucasg) is a continuity risk. The codebase has a mixed C#/C++/C++ /clr hybrid requiring Visual C++ Redistributable, which adds deployment friction. No visible unit test files suggest fragility in regression detection. The project appears stable for v1.x but lacks automated test infrastructure to prevent breaking changes.

Latest release is v1.11.1 (active development). Recent work includes bugfixes, incremental improvements, COVID-era maintenance, Windows 8.1 API set parsing, LLVM demangler integration, WOW64 FsRedirection fixes, F5 refresh support, and optional packaging without Peview.exe to avoid AV false positives. No visible open PRs or active issue tracking in provided data.

Clone: git clone https://github.com/lucasg/Dependencies.git. Open Dependencies.sln in Visual Studio (requires Visual C++ toolset for /clr compilation and MSVC C++ Redistributable pre-installed). Build via Visual Studio IDE or msbuild Dependencies.sln. Run DependenciesGui.exe or Dependencies.exe from bin output.

Daily commands: GUI: Build Dependencies.sln in Release config, run DependenciesGui.exe <optional_path_to_dll_or_exe>. CLI: Run Dependencies.exe <path_to_analyze> [options] to get dependency tree in console output.

• DependenciesGui/MainWindow.xaml.cs — Entry point for the GUI application; orchestrates module loading, dependency resolution, and UI state management.
• DependenciesLib/FindPeModule.cs — Core logic for locating and resolving PE module dependencies; every dependency lookup flows through this.
• ClrPhlib/src/managed/PE.cpp — Managed wrapper around PE file parsing; bridges C# code with unmanaged PE parsing and symbol resolution.
• DependenciesLib/BinaryCache.cs — Caches parsed PE binaries and their metadata to avoid redundant disk I/O and parsing overhead.
• DependenciesGui/Models/ModuleInfo.cs — Data model representing a loaded module; used throughout UI layers to display and track module state.
• ClrPhlib/include/ClrPhlib.h — Public C++/CLI interface that exposes unmanaged PE parsing capabilities to C# code.

Add a new search path strategy

1. Edit DependenciesLib/FindPeModule.cs to add a new method in the module search chain (e.g., custom registry lookup). (DependenciesLib/FindPeModule.cs)
2. Update DependenciesGui/UserSettings.xaml.cs to expose the new search path setting in the UI. (DependenciesGui/UserSettings.xaml.cs)
3. Persist the setting in DependenciesGui/Settings.cs. (DependenciesGui/Settings.cs)

Add a new tab showing additional module metadata

1. Create a new .xaml and .xaml.cs file in DependenciesGui/ following the naming convention of DependencyImportList.xaml. (DependenciesGui/DependencyImportList.xaml.cs)
2. Add a new ViewModel class in DependenciesGui/Models/ to bind the new data. (DependenciesGui/Models/PeImport.cs)
3. Register the new tab in DependenciesGui/DependencyWindow.xaml.cs using DragablzCustomHeader. (DependenciesGui/DependencyWindow.xaml.cs)

Extend PE parsing to extract additional binary metadata

1. Add a new C++/CLI managed method in ClrPhlib/src/managed/PE.cpp wrapping unmanaged parsing logic. (ClrPhlib/src/managed/PE.cpp)
2. Expose the new method in ClrPhlib/include/ClrPhlib.h as a public C++/CLI interface. (ClrPhlib/include/ClrPhlib.h)
3. Call the new method from DependenciesLib/FindPeModule.cs or a new utility class to populate ModuleInfo. (DependenciesLib/FindPeModule.cs)

Implement a new import resolution filter or status check

1. Add a filter method to DependenciesGui/FilterControl/FilterControl.cs to filter imports by a new criterion. (DependenciesGui/FilterControl/FilterControl.cs)
2. Update DependenciesGui/Models/PeImport.cs to include the new status/metadata field. (DependenciesGui/Models/PeImport.cs)
3. Modify DependenciesLib/FindPeModule.cs to populate the new field during import resolution. (DependenciesLib/FindPeModule.cs)

• C++/CLI (ClrPhlib) — Enables safe, efficient PE file parsing at the binary level while maintaining C# interop; PE parsing is CPU-intensive and benefits from native code speed.
• WPF + XAML — Provides rich, responsive desktop UI with data binding and tabbed navigation; standard choice for Windows developer tools.
• In-memory cache (BinaryCache) — Avoids repeated disk I/O and PE parsing for the same modules during dependency tree traversal, improving responsiveness.
• Windows API (FindPeModule search paths) — Replicates Windows loader behavior to resolve imports from system directories, APP directory, and PATH environment variable.

• C++/CLI for PE parsing instead of pure C#

  • Why: Requires Visual C++ Redistributable but enables fast binary parsing and direct Windows API calls.
  • Consequence: Deployment dependency on VC++ runtime; users must install redistributable. Mitigated by pre-built releases.

• In-memory cache with no persistence

  • Why: Simplifies cache invalidation and avoids stale data between sessions.
  • Consequence: Cache is lost on app exit; no speedup for first-time runs, but repeated analysis within one session is fast.

• Recursive module resolution without parallelization at module level

  • Why: Simpler logic and avoids thread-safety issues with Windows PE parsing.
  • Consequence: Large dependency trees may take seconds to resolve; acceptable for developer workflows.

• Linux or macOS support (Windows-only PE/DLL format)
• Real-time monitoring of module load events
• Modification or pat

Visual C++ Redistributable required: Project uses /clr mixed-mode compilation, so binaries will not run without the MSVC runtime installed—document this prominently in issue templates. WOW64 FsRedirection: 32-bit Dependencies.exe running on 64-bit Windows will see redirected paths; v1.9 added fixes but this is a subtle gotcha. Symbol provider initialization: ClrPhSymbolProvider must be initialized with correct search paths or symbol demangling fails silently—see PhSymbolProvider.cpp constructor. Peview.exe AV false positives: Some antivirus flag the bundled Peview.exe binary; v1.11 added optional builds without it. API set schema version mismatch: ApiSet.h parsing depends on Windows version; analyzing binaries on older Windows may miss modern API set aliases.

• Portable Executable (PE) Format — Understanding PE headers, sections (IAT, EAT), and relocation tables is essential to parsing imports/exports in ClrPhlib/src/managed/PE.cpp and PeImport.cpp.
• Import Address Table (IAT) and Import Descriptor — PeImport.cpp directly manipulates IAT structures to extract DLL/function names; understanding this is critical for modifying dependency resolution logic.
• Export Address Table (EAT) — PeExport.cpp parses EAT to enumerate exported symbols; this is how Dependencies validates that imports can be satisfied and displays available APIs.
• API Set Schema (Windows API Abstraction) — Modern Windows uses API sets to alias kernel APIs; ApiSet.h parsing enables Dependencies to resolve modern imports that do not directly reference kernel32.dll.
• Mixed-Mode C++/CLI Assembly — ClrPhlib uses /clr to bridge managed (C#) and unmanaged (Win32 PE parsing) code; understanding this compilation model is essential for debugging interop issues and modifying ClrPhlib.
• WOW64 File System Redirection — 32-bit processes on 64-bit Windows see redirected paths (System32 → SysWOW64); v1.9 added fixes for this subtle issue that causes missed dependencies.
• Symbol Demangling (C++ Name Mangling) — demangle.cpp and LLVM demangler support decode C++ mangled names back to human-readable symbols; essential for analyzing C++ DLL exports and troubleshooting unresolved symbol issues.

• lucasg/phlib — Companion library providing lower-level Win32 utilities (handles, processes, modules) that ClrPhlib likely depends on for system introspection.
• dlvhex/pe-tools — Alternative PE parsing toolkit in Python; useful for cross-platform dependency analysis and comparison with Dependencies' approach.
• mandiant/dnfile — Mandiant's Python PE parser; comparison tool for validating PE parsing logic in ClrPhlib against another reference implementation.
• torvalds/linux — Linux kernel; while not directly related, API set schema parsing in Dependencies mirrors how Linux handles symbol versioning—conceptually similar.
• microsoft/microsoft-ui-xaml — Microsoft's WinUI/XAML libraries; DependenciesGui uses WPF but could benefit from modernizing to WinUI 3 for better Windows 11 integration.

To work on one of these in Claude Code or Cursor, paste: Implement the "<title>" PR idea from CLAUDE.md, working through the checklist as the task list.

Add unit tests for ClrPhlib native C++ PE parsing modules

The ClrPhlib directory contains critical PE file parsing logic (PE.cpp, PeExport.cpp, PeImport.cpp, UnmanagedPE.cpp) that handles DLL dependency resolution, but there are no visible test files. Given this is a rewrite of the legacy depends.exe tool, comprehensive tests for PE header parsing, export/import table reading, and API set resolution would catch regressions and improve maintainability. This is especially important since the tool is used for production troubleshooting.

• [ ] Create ClrPhlib/tests directory with C++ test project using a framework like Google Test
• [ ] Add tests for PE.cpp covering valid/invalid PE files, 32/64-bit detection, and architecture validation
• [ ] Add tests for PeExport.cpp and PeImport.cpp covering export/import table parsing with real DLL samples
• [ ] Add tests for ApiSet.h resolution logic to verify API set mappings work correctly across Windows versions
• [ ] Integrate tests into Dependencies.sln and CI/CD (AppVeyor) to run on each commit

Add GitHub Actions CI workflow for automated Release builds

The repo uses AppVeyor (shown in README badge), but there's no visible GitHub Actions workflow file (.github/workflows/). Modern GitHub repos benefit from Actions for multi-platform builds, automated artifact generation for releases, and better integration with the GitHub UI. This would streamline the release process shown in the README (currently manual zip downloads for x64_Release and the peview variant).

• [ ] Create .github/workflows/build-release.yml to build both x64_Release and x64_Release_.without.peview configurations
• [ ] Configure the workflow to trigger on tag pushes (e.g., v*..) to automatically create GitHub release artifacts
• [ ] Add matrix builds for Release configuration and verify Visual C++ Redistributable requirement is documented in artifact metadata
• [ ] Update README to reference GitHub Actions badge alongside or instead of AppVeyor
• [ ] Test end-to-end: create a test tag and verify artifacts are generated correctly

Create DependenciesGui/Tests directory with XAML/ViewModel unit tests

DependenciesGui contains multiple XAML views (DependencyWindow.xaml, DependencyCustomListView.xaml, DependencyImportList.xaml, etc.) and ViewModels (CustomHeaderViewModel.cs), but no visible test files for the UI layer. Adding tests for ViewModels (filtering, sorting logic in GridViewSort.cs, RelayCommand.cs) and integration tests for XAML data binding would improve reliability of the GUI component and make future refactoring safer.

• [ ] Create DependenciesGui/Tests directory with a C# test project (using xUnit or NUnit)
• [ ] Add ViewModel unit tests for CustomHeaderViewModel.cs covering property changes and command execution
• [ ] Add tests for GridViewSort.cs covering sort direction changes, column selection, and event handling
• [ ] Add tests for FilterControl/FilterControl.cs covering filter application logic and view updates
• [ ] Add integration tests for DependencyWindow data binding using a mocking framework (e.g., Moq) to verify ListView data sources update correctly

• Add unit tests for ClrPhlib/src/managed/PE.cpp: The core PE parser has no visible test coverage; create xUnit or NUnit tests covering PE header parsing, section enumeration, and edge cases (truncated binaries, corrupted headers) to catch regressions early.
• Document CLI tool usage and add --help output: Dependencies.exe (Program.cs) is undocumented; add argument parsing (e.g. --output-format json|tree|csv), a help menu, and update README with CLI examples for scripting and automation workflows.
• Implement import tree filtering in GUI: DependencyCustomListView.xaml currently shows all imports; add a filter control (like FilterControl/ stub) to search/hide specific DLLs or unresolved imports, matching Dependency Walker's filtering UI.

• High · Use of Unmanaged C++ Code with Potential Buffer Overflow Risks — ClrPhlib/src/unmanaged/, particularly UnmanagedPE.cpp and UnmanagedSymPrv.cpp. The codebase extensively uses unmanaged C++ code (ClrPhlib) for PE file parsing and symbol resolution. Unmanaged code in ClrPhlib/src/unmanaged/ components lacks memory safety guarantees and could be vulnerable to buffer overflows, use-after-free, or other memory corruption issues when parsing untrusted DLL files. Fix: Implement strict bounds checking, use safe string handling functions, enable Address Sanitizer (ASAN) during development, and conduct thorough fuzzing of PE parsing logic with malformed files. Consider adding input validation and size limits for parsed structures.
• High · Arbitrary DLL Loading and Execution Risk — Dependencies/Program.cs, ClrPhlib/src/managed/NativeFile.cpp. As a dependency analysis tool that loads and analyzes DLLs, the application may be vulnerable to DLL hijacking or loading malicious DLLs if directory precedence is not carefully managed. The tool appears to analyze arbitrary DLLs without sufficient validation of their source or integrity. Fix: Implement DLL signature verification, use SetDllDirectory to restrict DLL search paths, validate DLL integrity before loading, and document security considerations for analyzing untrusted binaries. Consider running analysis in a sandboxed environment.
• Medium · Missing Input Validation on File Paths — DependenciesGui/MainWindow.xaml.cs, Dependencies/Program.cs. The application accepts file paths from user input (via GUI or CLI) but there's no visible validation for path traversal attacks or malformed paths that could access unintended files on the system. Fix: Implement comprehensive path validation: normalize paths, check for directory traversal sequences (../, ..), verify the file exists before processing, and restrict analysis to user-intended directories. Use Path.GetFullPath() and validate against expected locations.
• Medium · Potential Information Disclosure via Error Messages — DependenciesGui/App.xaml.cs, ClrPhlib/src/managed/Phlib.cpp. The application may expose sensitive system information (full file paths, system architecture details, or unhandled exception details) through error messages or logging, which could aid attackers in reconnaissance. Fix: Implement sanitized error handling that logs detailed errors securely while displaying user-friendly messages. Avoid exposing full file paths, system configuration details, or stack traces in user-facing error dialogs.
• Medium · Dependency on Visual C++ Redistributable Without Version Pinning — README, ClrPhlib/ClrPhlib.vcxproj. The application requires Visual C++ Redistributable but the README doesn't specify minimum versions or patch levels. Using outdated redistributables could expose the application to known vulnerabilities in the runtime. Fix: Document the minimum required Visual C++ Redistributable version with specific patch levels. Consider embedding version checks at runtime and prompting users to update if necessary. Specify the exact redistributable version in installation instructions.
• Low · Missing Security Headers and Manifest Information — DependenciesGui/Dependencies.manifest, ClrPhlib/ClrPhlib.manifest. The application includes manifest files (Dependencies.manifest, ClrPhlib.manifest) but Windows security best practices like requestedExecutionLevel, UAC elevation requirements, and dependency manifests should be reviewed to ensure proper security configurations. Fix: Review and properly configure manifest files with appropriate requestedExecutionLevel, enable Data Execution Prevention (DEP), and ensure all dependencies are properly declared. Add security-focused manifest attributes.
• Low · No Visible Integrity Checking or Code Signing — Project root, build configuration. The file structure shows no evidence of code signing, authenticated releases, or integrity verification mechanisms. This makes it difficult for users to verify they're running legitimate builds. Fix: Implement code signing with a trusted certificate for executable releases. Publish signed manifests or checksums alongside releases. Document the signing process and provide verification instructions for users.
• Low · Sensitive Operations Without Audit Logging — undefined. The application analyzes system DLLs and imports/exports but appears to lack any logging or audit trail of what was analyzed, Fix: undefined
