+### Repomap - Context Window Optimization
+
+**MANDATORY: Load repomap at session start and use proactively throughout development.**
+
+#### Session Start Protocol
+
+**ALWAYS load .repomap.txt as the first action** when starting any development session:
+
+```bash
+# At session start - load existing repomap
+cat .repomap.txt
+```
+
+**Purpose**: Provides token-optimized codebase context for AI-assisted development, reducing context window usage while maintaining code understanding.
+
+**Note**: The .repomap.txt file is tracked in git and should already exist. Only regenerate it when structural changes occur.
+
+#### Proactive Usage Throughout Development
+
+**Use repomap context in these scenarios**:
+
+1. **Planning implementations** - Review repomap before designing features
+2. **Understanding dependencies** - Check which files/classes exist before creating new ones
+3. **Code reviews** - Reference structure when reviewing changes
+4. **Refactoring** - Understand impact scope across codebase
+5. **Documentation** - Ensure docs reflect actual code structure
+
+#### When to Regenerate
+
+**Regenerate repomap when**:
+
+- Files are added or removed
+- Classes or functions are added/removed
+- Major refactoring is completed
+- Before creating PRs (ensure map is current)
+
+```bash
+# Regenerate after changes
+python repomap.py . > .repomap.txt
+git add .repomap.txt  # Include in commits
+```
+
+#### Integration with Development Workflow
+
+**Include repomap in commit tracking**:
+
+```bash
+# Pre-commit: Update repomap
+python repomap.py . > .repomap.txt
+git add .repomap.txt
+
+# Commit message references structure changes
+git commit -m "Add UserService class
+
+Updated repomap to reflect new service layer structure"
+```
+
+**Use in AI prompts**:
+
+- Reference specific files/classes from repomap by name
+- Ask questions about structure (e.g., "Where should I add authentication logic?")
+- Validate assumptions (e.g., "Does a Config class already exist?")
+
+#### Repomap Best Practices
+
+- ✅ Load at session start (always)
+- ✅ Regenerate after structural changes
+- ✅ Reference in planning and design discussions
+- ✅ Include in commit workflow
+- ✅ Use to avoid duplicate implementations
+- ❌ Don't rely on stale repomaps
+- ❌ Don't skip regeneration before PRs

+# Repomap - AI-Friendly Code Structure Maps
+
+Generate clean, token-optimized code structure maps using tree-sitter for AI-assisted development.
+
+**Inspired by**: [Aider's repomap.py](https://github.com/Aider-AI/aider/blob/main/aider/repomap.py)
+
+**Purpose**: Reduce context window tokens while maintaining code understanding, improving AI performance and reducing costs.
+
+## Quick Start
+
+```bash
+# Install dependencies
+pip install -r requirements.txt
+
+# Generate map of current directory
+python repomap.py .
+
+# Save to file
+python repomap.py . > repomap.txt
+
+# Map specific directory with verbose output
+python repomap.py /path/to/repo --verbose
+```
+
+## Installation
+
+### Requirements
+
+- Python 3.11+
+- pip or uv package manager
+
+### Install Dependencies
+
+```bash
+# Using pip
+pip install tree-sitter tree-sitter-python tree-sitter-javascript tree-sitter-typescript tree-sitter-go tree-sitter-bash
+
+# Using uv (recommended)
+uv pip install -r requirements.txt
+```
+
+## Usage
+
+### Basic Usage
+
+```bash
+# Map current directory
+python repomap.py .
+
+# Map specific directory
+python repomap.py /path/to/repo
+
+# Show verbose output (processing details, warnings)
+python repomap.py . --verbose
+
+# Disable parallel processing
+python repomap.py . --no-parallel
+
+# Set maximum file size (default: 1MB)
+python repomap.py . --max-file-size 2097152  # 2MB
+```
+
+### Save Output
+
+```bash
+# Save to file
+python repomap.py . > repomap.txt
+
+# Copy to clipboard (macOS)
+python repomap.py . | pbcopy
+
+# Copy to clipboard (Linux)
+python repomap.py . | xclip -selection clipboard
+```
+
+## Output Format
+
+Repomap generates a clean tree structure showing:
+
+- File hierarchy
+- Code symbols (classes, functions, methods, interfaces, structs)
+- Nesting relationships
+
+### Example Output
+
+```text
+src/
+  main.py
+    class Application
+      def __init__()
+      def run()
+    def main()
+  utils/
+    helpers.py
+      def sanitize_string()
+      def validate_slug()
+    config.py
+      class Config
+        def load()
+```
+
+## Supported Languages
+
+| Language   | Extensions       | Symbols Extracted                    |
+| ---------- | ---------------- | ------------------------------------ |
+| Python     | `.py`            | Functions, Classes, Methods          |
+| JavaScript | `.js`            | Functions, Classes                   |
+| TypeScript | `.ts`, `.tsx`    | Functions, Classes, Interfaces       |
+| Go         | `.go`            | Functions, Methods, Structs          |
+| Shell      | `.sh`, `.bash`   | Functions                            |
+
+## Features
+
+### Automatic Filtering
+
+Repomap automatically skips:
+
+- Binary files (detected via null bytes)
+- Large files (>1MB by default, configurable)
+- Files matching `.gitignore` patterns
+- Common ignore patterns (`.git`, `__pycache__`, `node_modules`, `.venv`, etc.)
+
+### Performance Features
+
+- **Parallel processing**: Uses multiprocessing for faster parsing (disable with `--no-parallel`)
+- **Efficient parsing**: Tree-sitter provides fast, incremental parsing
+- **Smart filtering**: Skips irrelevant files before parsing
+
+### Error Handling
+
+- Gracefully handles parse errors (continues processing other files)
+- Skips unsupported file types silently
+- Reports errors in verbose mode (`--verbose`)
+
+## Use Cases
+
+### 1. Local Development
+
+```bash
+# Generate map for AI context
+python repomap.py . > repomap.txt
+
+# Use in AI prompts
+cat repomap.txt | pbcopy  # Copy to clipboard
+```
+
+### 2. CI/CD Integration
+
+#### GitHub Actions
+
+```yaml
+# .github/workflows/generate-repomap.yml
+name: Generate Repomap
+on: [push, pull_request]
+
+jobs:
+  repomap:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+
+      - name: Set up Python
+        uses: actions/setup-python@v5
+        with:
+          python-version: '3.11'
+
+      - name: Install dependencies
+        run: pip install tree-sitter tree-sitter-python tree-sitter-javascript tree-sitter-typescript tree-sitter-go tree-sitter-bash
+
+      - name: Generate repomap
+        run: python repomap.py . > repomap.txt
+
+      - name: Upload artifact
+        uses: actions/upload-artifact@v4
+        with:
+          name: repomap
+          path: repomap.txt
+```
+
+#### GitLab CI
+
+```yaml
+# .gitlab-ci.yml
+generate_repomap:
+  stage: build
+  image: python:3.11
+  script:
+    - pip install tree-sitter tree-sitter-python tree-sitter-javascript tree-sitter-typescript tree-sitter-go tree-sitter-bash
+    - python repomap.py . > repomap.txt
+  artifacts:
+    paths:
+      - repomap.txt
+```
+
+### 3. Pre-commit Hook
+
+```bash
+# .git/hooks/pre-commit
+#!/bin/bash
+python repomap.py . > .repomap.txt
+git add .repomap.txt
+```
+
+## Configuration
+
+### File Size Limit
+
+Control maximum file size to parse:
+
+```bash
+# Default: 1MB (1048576 bytes)
+python repomap.py . --max-file-size 2097152  # 2MB
+```
+
+### Gitignore Patterns
+
+Repomap automatically respects `.gitignore` patterns in the repository root.
+
+**Default ignore patterns** (always applied):
+
+- `.git`
+- `__pycache__`
+- `node_modules`
+- `.venv`
+- `venv`
+- `*.pyc`
+- `.DS_Store`
+
+## Limitations
+
+### Current Version (v1.0)
+
+- **No caching**: Always recomputes (acceptable performance trade-off)
+- **Simple gitignore**: Basic pattern matching (not full gitignore spec)
+- **No incremental updates**: Generates full map on each run
+- **Limited symbol extraction**: Focuses on primary code symbols (functions, classes)
+
+### Future Enhancements
+
+Potential improvements for future versions:
+
+- File-level caching (only reparse changed files)
+- Full gitignore specification support
+- Additional symbol types (variables, imports, exports)
+- Configurable output formats (JSON, Markdown, etc.)
+- Symbol filtering (include/exclude patterns)
+
+## Performance
+
+**Benchmark**: Medium-sized repository (~1000 files)
+
+- **Sequential**: ~15-20 seconds
+- **Parallel**: ~5-8 seconds (on multi-core systems)
+
+**Optimization tips**:
+
+- Use `--max-file-size` to skip large generated files
+- Ensure `.gitignore` excludes build artifacts and dependencies
+- Use `--no-parallel` only for debugging (slower)
+
+## Troubleshooting
+
+### Import Errors
+
+**Problem**: `ImportError: No module named 'tree_sitter'`
+
+**Solution**: Install dependencies
+
+```bash
+pip install -r requirements.txt
+```
+
+### Parse Errors
+
+**Problem**: Files not showing symbols or "Error" messages in verbose mode
+
+**Possible causes**:
+
+- Syntax errors in source files
+- Unsupported language features
+- Encoding issues (non-UTF-8 files)
+
+**Solution**: Run with `--verbose` to see detailed error messages
+
+```bash
+python repomap.py . --verbose
+```
+
+### Performance Issues
+
+**Problem**: Slow parsing on large repositories
+
+**Solutions**:
+
+- Reduce `--max-file-size` to skip large files
+- Update `.gitignore` to exclude build artifacts
+- Use parallel processing (default, faster on multi-core systems)
+
+## Contributing
+
+This is a reference implementation. Contributions welcome:
+
+- Additional language support
+- Performance optimizations
+- Enhanced gitignore pattern matching
+- Additional output formats
