v0.1.2

[0.1.2] - 2026-06-28

UX improvements: window state persistence, drag-and-drop, toast
notifications, About dialog as AXAML, and expanded test coverage.

Added

• Window state persistence: MainWindow size, position, and maximized
  state are saved to AppConfiguration on close and restored on next
  launch. Multi-monitor negative coordinates are handled; sanity guards
  prevent restoring invalid geometry.
• Drag-and-drop support: dropping a folder onto the window opens it as
  a project; dropping a file reads its content and injects it into the
  active chat tab's input box as a fenced code block for LLM context.
• Toast notification system: transient overlay notifications (Info,
  Success, Warning, Error) displayed in the bottom-right corner with
  auto-dismiss. Triggered on project load, index rebuild success/failure,
  and index prewarm failure. Severity-colored icons (ℹ ✓ ⚠ ✗) via
  shared theme brushes.
• AboutWindow.axaml: dedicated AXAML window for the About dialog,
  replacing the inline code-built Window. Version is bound from
  AssemblyInformationalVersion (MinVer).
• Unit tests for QuickReferenceViewModel (9 tests): callbacks, classes,
  mod structure loading, sorting, no duplicates, REPENTOGON callbacks.
• Unit tests for TemplateGalleryViewModel (11 tests): template loading,
  scaffold validation, file creation, placeholder substitution, Lua
  string escaping, default name fallback.
• Unit tests for ToastService (12 tests): show info/success/warning/
  error, multiple toasts, dismiss, notification properties, icon
  mapping, custom duration.
• 4 toast colors added to Theme.axaml (info/success/warning/error).

Changed

• AppConfiguration.Save() now persists window state fields alongside
  existing LLM/embedding settings.
• MainViewModel exposes ToastService via Toasts property for UI
  binding.
• MainWindow.OnAbout simplified to create AboutWindow instead of
  building a Window inline.

v0.1.1

[0.1.1] - 2026-06-28

UI layer improvements: dynamic version display, DI consistency, shared
theme system, Markdown table rendering, recursive file tree, and expanded
test coverage.

Added

• Markdown table rendering: GFM-style tables (| col | col | with
  |---|---| separator) are now rendered as monospace, column-aligned
  text with a dashed separator line. Supports auto-sized columns,
  colon-aligned separators, escaped pipes, and missing trailing pipes.
• Shared theme system (Styles/Theme.axaml): 24 semantic color and 24
  brush resources centralized in a single resource dictionary, replacing
  30+ hardcoded color values across AXAML and C#.
• Recursive file tree: project files are displayed in a TreeView with
  expandable/collapsible directory nodes instead of a flat list. Build
  artifacts (.git, bin, obj) are excluded; empty directories are skipped;
  top-level directories are expanded by default.
• Unit tests for ChatTabViewModel (16 tests): send/cancel, streaming
  accumulation, error handling, IsGenerating state, ClearMessages,
  OnProjectChanged, ToggleExpand, Dispose.
• Unit tests for ChatViewModel (16 tests): multi-tab management, active
  tab switching, close behavior, project change propagation.
• Unit tests for MarkdownRenderer (20 tests): table rendering, existing
  markdown features regression, edge cases.
• RenderToText internal helper on MarkdownRenderer for testability.
• Shared Avalonia test infrastructure (AvaloniaTestHelper +
  AvaloniaFixture + AvaloniaTestCollection): serializes
  Avalonia-dependent tests via xUnit collection fixture to fix
  thread-safety issues with StyledElement static constructors under
  parallel test execution.

Changed

• About dialog now reads the version from AssemblyInformationalVersion
  (set by MinVer from git tags) instead of a hardcoded string.
• TemplateGalleryViewModel is now registered in the DI container and
  resolved via GetRequiredService, matching the pattern used by all
  other view models.
• All hardcoded color values in AXAML views, converters,
  ChatMessageViewModel, and MarkdownRenderer now resolve brushes via
  Application.Current.Resources with semantic resource keys.
• File tree double-click only opens files (not directories) for preview.
• OnFileDoubleTapped handles both TreeView and ListBox sources.

Fixed

• Avalonia headless test initialization race condition: multiple test
  classes initializing the headless application via static constructors
  could race under parallel test execution, causing
  StyledElement..cctor failures. Consolidated into a single
  collection fixture.

v0.1.0-preview2

IsaacAgent v0.1.0-preview2

Second preview release — focused on expanding the knowledge base and improving agent workflow guidance.

What's New

Pattern library expanded: 11 to 25

• 14 new code patterns: item pool modification, custom curse, achievement tracking, custom HUD, custom tear effect, advanced familiars (orbit/shoot/buff), custom shop, custom devil room, custom door, custom pedestal, custom status effect, custom music, custom cutscene, multiplayer sync

Few-shot workflow examples

• 5 guided workflows added to the system prompt: create collectible, debug runtime error, validate project, add save data, create familiar
• Each workflow specifies the exact tool call sequence, improving agent stability for multi-step tasks

Enhanced tool descriptions

• 8 tool descriptions improved with usage guidance (e.g., "always call validate_xml after modifying XML", "use parse_log as first step when user reports a crash")
• get_pattern description now lists all 25 available pattern names
