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/sourcegit-scm/sourcegit 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.

SourceGit is a cross-platform desktop Git GUI client written in C# (Avalonia-based) for Windows, macOS, and Linux. It provides a visual interface for Git operations—clone, fetch, pull, push, merge, rebase, cherry-pick, interactive rebase, and advanced workflows like bisect and worktrees—plus built-in features like commit graph visualization, SSH per-remote support, Git LFS, GitFlow, AI-powered commit messages, and issue linking to GitHub/GitLab/Gitea/Gitee/Bitbucket. Monolith desktop app: src/AI/ (AI agent and chat tools), src/ contains core logic (implied structure based on typical Avalonia projects), build/resources/ holds platform-specific assets (macOS .icns/.plist, Linux .desktop/.metainfo, DEB/RPM/AppImage specs), and build/scripts/ contains packaging automation (PowerShell for Windows, shell scripts for macOS/Linux).

Git users on desktop (Windows/macOS/Linux) who prefer a GUI over CLI for repository management, branch workflows, and visual commit history—especially developers working with multiple remotes, interactive rebases, or complex merge scenarios who want to avoid CLI scripts.

Actively developed and production-ready. The repo has significant GitHub stars, supports 14+ languages, ships multi-platform installers (DEB, RPM, AppImage, macOS .app, Windows MSI via build scripts in build/scripts/), and maintains CI/CD workflows (build.yml, package.yml, release.yml). Commit activity and recent releases indicate ongoing maintenance, though the single primary maintainer (implied by repo structure) is a minor risk factor.

Low risk for a mature GUI application. No high-risk dependency sprawl visible (C# ecosystem is typically well-managed), but Linux support is only tested on Debian 12 (X11 & Wayland)—portability to other distros untested. The portable-mode feature (data folder next to executable) could mask configuration issues. Monitor the single-maintainer situation for long-term sustainability.

Active feature development: latest workflows show package.yml and release.yml running regularly, AI commit-message generation is integrated, multi-language localization is maintained (localization-check.yml), and platform-specific packaging is automated. Recent additions likely include UI polish, theme customization, and deeper Git command coverage.

1. Install Git (≥2.25.1). 2. Clone: git clone https://github.com/sourcegit-scm/sourcegit.git. 3. Open SourceGit.slnx in Visual Studio or dotnet build from the root. 4. Run the compiled binary or dotnet run if a launch configuration exists.

Daily commands:

1. dotnet restore (resolve dependencies from global.json). 2. dotnet build or dotnet run from repo root. For platform-specific builds: Windows: build/scripts/package.win.ps1, macOS: build/scripts/package.osx-app.sh, Linux: build/scripts/package.linux.sh.

• src/App.axaml.cs — Main application entry point and lifecycle management for the Avalonia GUI framework
• src/Commands/Command.cs — Base abstraction for all Git command wrappers; every Git operation extends this class
• src/App.Commands.cs — Application command routing and orchestration layer that coordinates UI actions with Git commands
• src/Commands/QueryCommits.cs — Core commit history querying command; used extensively throughout the UI for commit display and navigation
• src/AI/Service.cs — AI integration service for commit message generation and code analysis features
• src/App.axaml — Root XAML markup defining application-wide styles, resources, and theme management

Add a new Git command operation

1. Create a new class in src/Commands/ that inherits from Command.cs base class (src/Commands/Command.cs)
2. Implement BuildArguments() method to construct git CLI arguments and Execute() to parse command output (src/Commands/YourCommand.cs)
3. Add a corresponding handler method in App.Commands.cs that instantiates and executes your command (src/App.Commands.cs)
4. Wire up the command to UI events (buttons, menu items) in XAML views by binding to the handler method (src/App.axaml.cs)

Add a new AI-powered feature

1. Define a new tool in ChatTools.cs that exposes Git data to the LLM (e.g., file changes, diff context) (src/AI/ChatTools.cs)
2. Add a new prompt template and LLM invocation method in Service.cs (src/AI/Service.cs)
3. Create an Agent.cs method to coordinate tool calls and LLM responses for your feature (src/AI/Agent.cs)
4. Integrate the AI service call into App.Commands.cs and bind UI controls to trigger the AI operation (src/App.Commands.cs)

Add a new theme or customize UI appearance

1. Define theme colors and styles in App.axaml under the Application.Styles section (src/App.axaml)
2. Create theme resource dictionaries (light/dark variants) with brush and font definitions (src/App.axaml)
3. Expose theme switching logic in App.axaml.cs to toggle between theme variants at runtime (src/App.axaml.cs)

Add support for a new Git workflow or extension

1. Create specialized Command classes in src/Commands/ for your workflow (e.g., GitFlow.cs pattern) (src/Commands/GitFlow.cs)
2. Implement workflow-specific operations by composing multiple Git commands (src/Commands/Command.cs)
3. Add orchestration methods in App.Commands.cs to manage multi-step workflow execution (src/App.Commands.cs)
4. Build dedicated UI panels or dialogs in XAML to guide users through the workflow steps (src/App.axaml)

• Avalonia Framework — Enables single codebase for Windows, macOS, and Linux GUI with XAML-based declarative UI and data binding
• .NET 8+ (C#) — Modern cross-platform runtime with strong type safety, async/await patterns, and native Windows/macOS/Linux support via CoreCLR
• Git CLI Invocation (subprocess) — Direct git executable wrapping provides universal compatibility (any git version) without reimplementing git internals
• LLM Integration (AI Service) — Optional GenAI layer for intelligent commit message generation, code review suggestions, and semantic search over changes

• Wrapping git CLI instead of using libgit2

  • Why: Simplicity, compatibility across git versions, and delegating complexity to battle-tested git binary
  • Consequence: Performance overhead for subprocess spawning on every operation; harder to implement real-time streaming diffs

• Single-threaded synchronous command execution model

  • Why: Sequential git commands match user intent (edit → stage → commit) and reduce concurrency bugs
  • Consequence: Long-running operations (push to slow remote) block UI; mitigated by async/await wrapper calls from orchestration layer

• Avalonia for cross-platform UI

  • Why: Unified XAML codebase shares 90%+ between Windows, macOS, Linux platforms
  • Consequence: Platform-specific polish requires per-OS customization; native feels less polished than native frameworks but saves development cost

• Optional opt-in AI service (not mandatory)

  • Why: Keeps core functionality independent of LLM availability and API keys
  • Consequence: AI features degrade gracefully if service unavailable; requires feature flag management in App.Commands

• Does not implement Git protocol directly; relies entirely on git CLI binary for all repository operations
• Not a real-time collaborative tool; designed for local or single-user workflows
• Does not provide authentication handling beyond git credential helpers; defers to system/git configuration
• Not a Git hosting platform; cannot create repositories on GitHub/GitLab (read-only from those platforms)

Platform-specific quirks: Linux support only tested on Debian 12; other distros may fail (GTK vs Qt mismatch, Wayland vs X11 issues). Portable mode logic: Creating a data/ folder next to the executable silently switches storage location—easy to miss in docs. SSH per-remote: Each remote must be manually configured with its own SSH key; no global fallback—requires understanding of SSH config. Git version requirement (≥2.25.1): Older systems may have incompatible Git; no version check visible in startup. AI service integration: src/AI/ likely requires API keys/network—check if offline mode is supported. Build dependencies: global.json pins .NET version; mismatches cause silent build failures.

• Interactive Rebase — SourceGit exposes interactive rebase (amend/reword/squash/reorder commits) as a core feature—understanding commit history rewriting is essential for reviewing changes and code archaeology.
• Worktrees — SourceGit lists worktrees as a supported feature—git worktrees allow multiple working directories from one repo, useful for parallel work on different branches without switching context.
• Cherry-pick — Cherry-pick (selectively apply commits from one branch to another) is a core SourceGit operation—differs from merge/rebase in scope and is crucial for backporting hotfixes.
• Git LFS (Large File Storage) — SourceGit supports Git LFS—essential for repos with large binaries (media, models); storing them in Git directly breaks performance, so LFS replaces them with pointers.
• Bisect — SourceGit lists git bisect as supported—binary search through commit history to find regression introduction; critical skill for debugging in large histories.
• GitFlow Workflow — SourceGit has built-in GitFlow support—GitFlow is a branching strategy (main/develop/feature/release/hotfix) widely used in larger teams; the GUI abstracts CLI complexity.
• SSH Per-Remote Authentication — SourceGit allows different SSH keys per remote (each remote configured separately)—critical for multi-account setups (work vs. personal GitHub), avoiding hardcoded global SSH config.

• gitextensions/gitextensions — Windows-first .NET Git GUI with similar feature breadth (commit graph, interactive rebase, merge conflict resolution)—closest competitor in the .NET ecosystem
• libgit2/libgit2 — C library for Git operations—SourceGit wraps git CLI, but libgit2 is the alternative foundation many GUI clients use for lower-level control
• sourcegit-scm/sourcegit-theme — Official theme repository—users customize SourceGit appearance by cloning themes from here
• GitKraken/gitkraken-client — Commercial cross-platform Git GUI with AI features and visual diff—market competitor with similar UX goals but proprietary
• magit/magit — Emacs-based Git interface—philosophical alternative for CLI-adjacent developers; demonstrates text-mode Git workflow paradigm SourceGit replaces with GUI

Add unit tests for src/Commands directory

The Commands directory contains critical git operation implementations (Add.cs, Branch.cs, Checkout.cs, CherryPick.cs, Clone.cs, etc.) but there are no visible test files in the repository structure. Given that these commands are the core business logic of a git client, adding unit tests would significantly improve code reliability and catch regressions. This is especially valuable for a GUI client where users depend on correct git operations.

• [ ] Create a new test project (e.g., src/Tests or tests/) following .NET conventions
• [ ] Start with unit tests for base Command.cs class to validate command execution patterns
• [ ] Add tests for high-risk commands: Checkout.cs, Merge.cs, Rebase.cs, Reset.cs to ensure data safety
• [ ] Integrate test execution into the existing CI pipeline (.github/workflows/ci.yml)
• [ ] Aim for >80% code coverage on the Commands namespace

Add AI/Agent.cs integration tests and documentation

The AI directory (src/AI/Agent.cs, Service.cs, ChatTools.cs) appears to be a significant feature but lacks visible documentation about how the AI integration works, what providers are supported, and how contributors can test it. This is a specialized feature that would benefit from clear integration test examples and a dedicated documentation file explaining the AI architecture, similar to TRANSLATION.md.

• [ ] Create docs/AI_INTEGRATION.md documenting the AI service architecture, supported providers, and configuration
• [ ] Add integration tests in src/AI/Tests/ covering Agent initialization, ChatTools functionality, and Service lifecycle
• [ ] Document API requirements and any external dependencies (OpenAI, etc.) in the AI section
• [ ] Add example configurations or environment variable setup instructions for contributors testing AI features

Implement platform-specific integration tests in CI/CD workflows

The repo has build scripts for Windows (.github/workflows/package.win.ps1), macOS (.github/workflows/package.osx-app.sh), and Linux (.github/workflows/package.linux.sh) but the existing CI workflows (ci.yml, build.yml) don't show explicit platform-specific test execution. Adding matrix testing across Windows/macOS/Linux in the CI pipeline would catch platform-specific bugs early and ensure consistency across all supported platforms.

• [ ] Extend .github/workflows/ci.yml to add matrix strategy for Windows, macOS, and Linux runners
• [ ] Create platform-specific test steps that validate GUI rendering, git command execution, and file path handling on each OS
• [ ] Reference the existing build scripts (package.win.ps1, package.osx-app.sh, package.linux.sh) as templates for platform-specific validation
• [ ] Ensure test results are reported clearly and block merges if any platform-specific tests fail

• Add unit tests for src/AI/Agent.cs and src/AI/ChatTools.cs—currently no test files visible in the repo structure, leaving AI features without regression coverage.
• Expand Linux platform testing: document and add CI steps for Ubuntu 22.04 LTS, Fedora, and Arch Linux to reduce Debian-12-only brittleness and catch distro-specific GTK/Wayland bugs early.
• Create a troubleshooting guide in docs/ or README for common SSH key setup mistakes per remote, since SSH configuration is manual and error-prone for new users unfamiliar with .ssh/config.

• High · Command Injection Risk in Git Command Execution — src/Commands/ directory. The codebase contains multiple Command classes (Add.cs, Commit.cs, etc.) that execute git commands. Without examining the actual implementation, there is a significant risk of command injection if user input is not properly sanitized before being passed to git operations. This is particularly critical in a Git GUI client that handles user-provided repository paths, branch names, and commit messages. Fix: Ensure all git command arguments are properly escaped and validated. Use parameterized command execution where possible rather than string concatenation. Implement strict input validation for repository paths, branch names, and file paths.
• High · Potential Path Traversal Vulnerability — src/Commands/ (all file operation commands). Git GUI applications often work with arbitrary repository paths and file operations. The codebase lacks visible path validation mechanisms. Without proper canonicalization and validation, attackers could potentially access files outside the intended repository directory using path traversal sequences like '../' or symlink attacks. Fix: Implement strict path validation using Path.GetFullPath() and verify all paths resolve within the expected repository directory. Reject paths containing '..', validate against a whitelist of allowed operations, and handle symlinks securely.
• Medium · Insecure Deserialization in AI/ChatTools and AI/Service — src/AI/ChatTools.cs, src/AI/Service.cs. The AI-related modules (AI/ChatTools.cs, AI/Service.cs) may be deserializing data from external sources (AI APIs, user input). Without visible sanitization, this could lead to arbitrary code execution or data tampering if untrusted data is deserialized. Fix: Use type-safe deserialization patterns, validate all incoming JSON/data against strict schemas, avoid using BinaryFormatter or other unsafe deserialization methods. Implement input validation and consider using JSON schema validation.
• Medium · Incomplete Dependency Visibility — Dependencies and package management files. The provided package dependency file content is empty. This means there's no visibility into the project's NuGet/package dependencies, which could hide known vulnerable packages. The project uses Avalonia UI framework and .NET which may have transitive dependencies with known vulnerabilities. Fix: Conduct a full dependency audit using 'dotnet list package --vulnerable' and tools like OWASP Dependency-Check. Keep all dependencies updated to the latest secure versions. Enable security scanning in CI/CD pipelines (e.g., GitHub Dependabot).
• Medium · Potential Information Disclosure in Diff/Blame Operations — src/Commands/Diff.cs, src/Commands/Blame.cs. Commands like Diff.cs and Blame.cs read file contents from git repositories. If error messages or stack traces are exposed to users without proper sanitization, sensitive information from file paths, git history, or system information could be disclosed. Fix: Implement generic error messages for user-facing errors. Log detailed errors securely server-side only. Sanitize all output from git commands before displaying to users.
• Medium · Unvalidated Clone/Fetch Operations — src/Commands/Clone.cs, src/Commands/Fetch.cs. The Clone.cs and Fetch.cs commands allow users to specify arbitrary Git repository URLs. Without validation, users could be tricked into cloning malicious repositories or exploiting git vulnerabilities. Additionally, MITM attacks on HTTP-based repositories are possible. Fix: Validate repository URLs using URL parsing libraries, warn users about HTTP vs HTTPS, enforce HTTPS for remote operations, verify SSH keys, and implement certificate pinning for critical repositories. Warn users before cloning from untrusted sources.
• Low · Missing Security Headers in Build Configuration — src/App.manifest, build/scripts/package.win.ps1. The Windows executable manifest (src/App.manifest) and packaging scripts lack explicit security hardening directives such as DEP (Data Execution Prevention) and ASLR (Address Space Layout Randomization) specifications. Fix: Enable DEP and ASLR in the Windows application manifest. Ensure all build scripts compile with /DYNAMICBASE and /NXCOMPAT flags.
• Low · Potential Sensitive Data in Build Artifacts — undefined. Build scripts (package.linux.sh, package.osx-app.sh, package. Fix: undefined
