+## Working with Roadmap
+
+When the user points to `ROADMAP.md` or asks about the roadmap/next steps:
+
+1. **Read both files together:**
+   - `packages/<package>/ROADMAP.md` - to understand the planned features and milestones
+   - `packages/<package>/CHANGELOG.md` - to see what's already implemented
+
+2. **Determine current position:**
+   - Check the latest version in CHANGELOG.md
+   - Cross-reference with ROADMAP.md milestones
+   - Identify which roadmap items are already completed (present in CHANGELOG)
+
+3. **Suggest next steps:**
+   - Find the first uncompleted item in the current milestone
+   - Or identify the next milestone if current one is complete
+   - Present clear "start here" recommendation
+
+**Example workflow:**
+```
+User: "Let's work on the roadmap" or points to ROADMAP.md
+
+Claude should:
+1. Read ROADMAP.md → See milestones v0.1.0, v0.2.0, v0.3.0...
+2. Read CHANGELOG.md → See latest release is v0.1.1
+3. Compare → v0.1.0 milestone complete, v0.2.0 in progress
+4. Report → "v0.1.0 is complete. For v0.2.0, next item is: <feature>"
+```

+  - Extracted `extractClassHeritage()`, `parseHeritageClause()`, `findTypeIdentifier()`, `collectImplements()` helper methods
+  - Max nesting depth reduced from 5 to 4
+- 🔄 **Refactored RedisStorage** - Removed unnecessary type parameter from `parseJSON()` method
+
+### Quality
+
+- ✅ **Zero lint warnings** - All ESLint warnings resolved
+- ✅ **All 321 tests pass**
+
+## [0.3.0] - 2025-11-30 - Indexer
+
+### Added
+
+- **FileScanner (0.3.1)**
+  - Recursive directory scanning with async generator
+  - `.gitignore` support via `globby` (replaced `ignore` package for ESM compatibility)
+  - Filters: binary files, node_modules, dist, default ignore patterns
+  - Progress callback for UI integration
+  - `isTextFile()` and `readFileContent()` static utilities
+  - 22 unit tests
+
+- **ASTParser (0.3.2)**
+  - Tree-sitter based parsing for TS, TSX, JS, JSX
+  - Extracts: imports, exports, functions, classes, interfaces, type aliases
+  - Import classification: internal, external, builtin (using `node:module` builtinModules)
+  - Graceful error handling with partial AST on syntax errors
+  - 30 unit tests
+
+- **MetaAnalyzer (0.3.3)**
+  - Complexity metrics: LOC (excluding comments), nesting depth, cyclomatic complexity, overall score
+  - Dependency resolution: internal imports resolved to absolute file paths
+  - Dependents calculation: reverse dependency lookup across all project files
+  - File type classification: source, test, config, types, unknown
+  - Entry point detection: index files, main/app/cli/server patterns, files with no dependents
+  - Hub detection: files with >5 dependents
+  - Batch analysis via `analyzeAll()` method
+  - 54 unit tests
+
+- **IndexBuilder (0.3.4)**
+  - SymbolIndex: maps symbol names to locations for quick lookup (functions, classes, interfaces, types, variables)
+  - Qualified names for class methods: `ClassName.methodName`
+  - DepsGraph: bidirectional import mapping (`imports` and `importedBy`)
+  - Import resolution: handles `.js` → `.ts`, index.ts, directory imports
+  - `findSymbol()`: exact symbol lookup
+  - `searchSymbols()`: regex-based symbol search
+  - `findCircularDependencies()`: detect import cycles
+  - `getStats()`: comprehensive index statistics (symbols by type, hubs, orphans)
+  - 35 unit tests
+
+- **Watchdog (0.3.5)**
+  - File watching with chokidar (native events + polling fallback)
+  - Debounced change handling (configurable, default 500ms)
+  - Event types: add, change, unlink
+  - Extension filtering (default: SUPPORTED_EXTENSIONS)
+  - Ignore patterns (default: DEFAULT_IGNORE_PATTERNS)
+  - Multiple callback support
+  - `flushAll()` for immediate processing
+  - Silent error handling for stability
+  - 21 unit tests
+
+- **Infrastructure Constants**
+  - `tree-sitter-types.ts`: NodeType and FieldName constants for tree-sitter
+  - Eliminates magic strings in ASTParser
+
+- **Dependencies**
+  - Added `globby` for ESM-native file globbing
+  - Removed `ignore` package (CJS incompatibility with nodenext)
+
+### Changed
+
+- Refactored ASTParser to use constants instead of magic strings
+- Total tests: 321
+- Coverage: 96.43%
+
+---
+
+## [0.2.0] - 2025-01-30
+
+### Added
+
+- **Redis Storage (0.2.x milestone)**
+  - RedisClient: connection wrapper with AOF persistence configuration
+  - RedisStorage: full IStorage implementation with Redis hashes
+  - Redis key schema: project files, AST, meta, indexes, config
+  - Session keys schema: data, undo stack, sessions list
+  - `generateProjectName()` utility for consistent project naming
+
+- **Infrastructure Layer**
+  - `src/infrastructure/storage/` module
+  - Exports via `src/infrastructure/index.ts`
+
+- **Testing**
+  - 68 new unit tests for Redis module
+  - 159 total tests
+  - 99% code coverage maintained
+
+### Changed
+
+- Updated ESLint config: `@typescript-eslint/no-unnecessary-type-parameters` set to warn
+
+### Notes
+
+Redis Storage milestone complete. Next: 0.3.0 - Indexer (FileScanner, AST Parser, Watchdog)
+
 ## [0.1.0] - 2025-01-29

+export const SYSTEM_PROMPT = `You are ipuaro, a local AI code assistant specialized in helping developers understand and modify their codebase. You operate within a single project directory and have access to powerful tools for reading, searching, analyzing, and editing code.
+
+## Core Principles
+
+1. **Lazy Loading**: You don't have the full code in context. Use tools to fetch exactly what you need.
+2. **Precision**: Always verify file paths and line numbers before making changes.
+3. **Safety**: Confirm destructive operations. Never execute dangerous commands.
+4. **Efficiency**: Minimize context usage. Request only necessary code sections.
+
+## Available Tools
+
+### Reading Tools
+- \`get_lines\`: Get specific lines from a file
+- \`get_function\`: Get a function by name
+- \`get_class\`: Get a class by name
+- \`get_structure\`: Get project directory structure
+
+### Editing Tools (require confirmation)
+- \`edit_lines\`: Replace specific lines in a file
+- \`create_file\`: Create a new file
+- \`delete_file\`: Delete a file
+
+### Search Tools
+- \`find_references\`: Find all usages of a symbol
+- \`find_definition\`: Find where a symbol is defined
+
+### Analysis Tools
+- \`get_dependencies\`: Get files this file imports
+- \`get_dependents\`: Get files that import this file
+- \`get_complexity\`: Get complexity metrics
+- \`get_todos\`: Find TODO/FIXME comments
+
+### Git Tools
+- \`git_status\`: Get repository status
+- \`git_diff\`: Get uncommitted changes
+- \`git_commit\`: Create a commit (requires confirmation)
+
+### Run Tools
+- \`run_command\`: Execute a shell command (security checked)
+- \`run_tests\`: Run the test suite
+
+## Response Guidelines
+
+1. **Be concise**: Don't repeat information already in context.
+2. **Show your work**: Explain what tools you're using and why.
+3. **Verify before editing**: Always read the target code before modifying it.
+4. **Handle errors gracefully**: If a tool fails, explain what went wrong and suggest alternatives.
+
+## Code Editing Rules
+
+1. Always use \`get_lines\` or \`get_function\` before \`edit_lines\`.
+2. Provide exact line numbers for edits.
+3. For large changes, break into multiple small edits.
+4. After editing, suggest running tests if available.
+
+## Safety Rules
+
+1. Never execute commands that could harm the system.
+2. Never expose sensitive data (API keys, passwords).
+3. Always confirm file deletions and destructive git operations.
+4. Stay within the project directory.
+
+When you need to perform an action, use the appropriate tool. Think step by step about what information you need and which tools will provide it most efficiently.`
