+  - Define `ThemeJson` interface with `$schema`, `defs`, and `theme` properties
+  - Define `ColorValue` type supporting hex colors, color references, variants, and RGBA
+  - Define `Variant` type for light/dark mode color definitions
+  - Export interfaces for type checking
+

+  - Document the theme structure in comments
+
+- Step 1.3: Create `src/themes/` directory
+  - Ensure directory exists for JSON theme files

+  - Define `theme` with semantic color mappings
+
+tests:
+- Unit:

+  - Implement `generateSystemTheme(colors: TerminalColors, mode: "dark" | "light"): ThemeJson`
+  - Use ANSI color references for primary colors
+  - Generate appropriate background colors
+  - Generate diff colors with alpha blending
+  - Generate markdown and syntax colors
+
+- Step 7.5: Add system theme caching
+  - Cache terminal palette detection results
+  - Handle palette cache invalidation
+  - Support manual cache clear on SIGUSR2
+
+tests:
+- Unit:
+  - Test `detectSystemTheme` returns correct mode
+  - Test `generateGrayScale` produces correct grays
+  - Test `generateMutedTextColor` produces readable colors
+  - Test `tint` produces correct blended colors
+  - Test `generateSystemTheme` produces valid theme JSON
+
+- Integration/e2e:
+  - Test system theme detection in terminal
+  - Test theme generation with actual terminal palette
+  - Verify light/dark mode detection is accurate
+
+acceptance_criteria:
+- `src/utils/system-theme.ts` file exists with detection functions
+- `src/utils/color-generation.ts` file exists with generation helpers
+- System theme detection works correctly
+- Light/dark mode detection is accurate
+- Theme generation produces valid JSON
+
+validation:
+- Run: `bun run typecheck` - Should pass
+- Run: `bun test src/utils/system-theme.test.ts`
+- Run: `bun test src/utils/color-generation.test.ts`
+- Test system theme detection manually in terminal
+- Verify theme colors are readable
+
+notes:
+- Use opencode's system theme detection as reference
+- Handle terminal transparency gracefully
+- Add fallback for terminals without palette support

+    - Types (function, class, module)
+    - Variables (parameter, member, builtin)
+    - Strings, numbers, booleans
+    - Comments
+    - Operators and punctuation
+    - Markdown-specific scopes (headings, bold, italic, links)

+- Step 8.2: Create `src/utils/syntax-highlighter.ts`
+  - Implement `generateSyntax(theme: ThemeColors)` function
+  - Implement `generateSubtleSyntax(theme: ThemeColors)` function
+  - Apply opacity to syntax colors for subtle highlighting
+  - Use theme's `thinkingOpacity` property
+
+- Step 8.3: Integrate with OpenTUI syntax highlighting
+  - Import `SyntaxStyle` from `@opentui/core`
+  - Use `SyntaxStyle.fromTheme()` to create syntax styles
+  - Apply syntax styles to code components
+
+- Step 8.4: Add syntax scope mappings
+  - Map common programming language scopes
+  - Map markdown and markup scopes
+  - Map diff and git scopes
+  - Add scope aliases for common patterns
+
+tests:
+- Unit:
+  - Test `getSyntaxRules` generates correct rules

+- Run: `bun run typecheck` - Should pass
+- Run: `bun test src/utils/syntax-rules.test.ts`
+- Run: `bun test src/utils/syntax-highlighter.test.ts`
