GRACE Context Manager — Assemble high-quality context for LLM coding assistants

GRACE Context Manager

A modern GUI tool for assembling high-quality context for LLM coding assistants. Built with PyQt6.

pip install grace-context-manager
grace

Upgrading

pip install --upgrade grace-context-manager

Your data is safe. All settings, context blocks, extension presets, and recent projects are stored in ~/.grace_manager/ — they persist across upgrades.

Key Features

• Context Blocks: Reusable text snippets organized by category (tech stack, constraints, rules). Toggle on/off as needed.
• Smart File Selection: Tree view with checkboxes, file size display, and quick select/deselect.
• Advanced Filtering: Filter by extension (typed manually or by checkboxes with two-way binding), keyword filename filter, and built-in ignore rules (dot-files, node_modules, __pycache__, venv).
• Dynamic Extension Detection: Auto-detect all file extensions in your project with select/deselect all for quick filtering.
• Typed Extension Filter: Extensions can be typed directly as comma-separated values (.py, .json, .yaml) or selected via checkboxes — both stay in sync.
• Extension Presets: Save frequently used extension combinations (e.g., python_ml, web_dev) and reload them across sessions.
• Live Preview: See assembled context with token count estimation before copying.
• Preview Modes: Full context, structure only, or files only.
• Dynamic Context Refresh: Refresh selected file contents when files change on disk without re-selecting.
• Scalable UI: Adjustable interface scaling (75%-200%) for different screen sizes and devices.
• Manual Directory Entry: Type the project root path directly or use Browse/Recent selectors.
• Keyboard Shortcuts: Ctrl+C copy, Ctrl+N new block, Ctrl+R refresh, Ctrl+O browse, Ctrl+A/D select all/none.

One-Click Installers (no Python required)

For users without Python, download and run the platform installer which bundles everything:

Platform	Installer
Windows	install.bat (right-click → "Run")
Linux / macOS	./install.sh

Manual Install (from source)

git clone https://github.com/VanUST/GRACE.git
cd grace-context-manager
pip install -e .

Workflow

1. Select Project: Click Browse to choose your project directory, select from Recent, or type the path directly.
2. Add Context Blocks: Create reusable blocks for tech stack, coding rules, etc.
3. Filter Extensions: Click Detect to auto-discover all file extensions, then:
   • Click checkboxes to toggle individual extensions
   • Type extensions directly in the text field (.py, .json, .yaml)
   • Use All/None for quick toggle
   • Save/Load presets for reuse across projects
4. Keyword Filter: Set a keyword to only show files matching that keyword in their filename.
5. Select Files: Check files/directories to include in context.
6. Add Instruction: Write your task in the instruction box.
7. Refresh: Click Refresh Context to reload changed files from disk.
8. Copy: Click Copy Context and paste into your LLM.

Extension Presets

Save and load extension filter combinations:

1. Select your desired extensions (via checkboxes or typing)
2. Click Save to store as a named preset (e.g., python_ml)
3. Click Load▾ to apply a previously saved preset
4. Presets persist globally in ~/.grace_manager/extension_presets.json

Built-in defaults: python_ml, web_dev, data_science, rust, golang, python, all.

Keyboard Shortcuts

Shortcut	Action
Ctrl+C	Copy context to clipboard
Ctrl+N	New context block
Ctrl+R	Refresh context
Ctrl+O	Browse directory
Ctrl+A	Select all files
Ctrl+D	Deselect all files

Running Tests

# Install test dependencies
pip install -e ".[test]"

# Run all tests
pytest tests/ -v

# Run specific test file
pytest tests/test_engine.py -v
pytest tests/test_tree_model.py -v
pytest tests/test_config.py -v

# Quick smoke test (no pytest required)
python -m pytest tests/

Tests run headless (virtual display) and cover:

• Engine: Token estimation, file scanning with extension/keyword filters, context assembly across all modes
• Tree model: Check/uncheck propagation, partial uncheck (Bug 1+2 fix), eager loading, extension & keyword filters, nested directory handling, dot-file exclusion
• Config: Built-in constants, ignore rules, extension presets

Context Blocks

Context blocks are saved in ~/.grace_manager/profiles.json. They persist across sessions.

Organize blocks by category:

• tech - Technology stack info
• constraints - Coding rules and constraints
• context - Project-specific context
• Any custom category

UI Scaling

Use the scale buttons in the sidebar to adjust the UI. Scaling preference is saved in ~/.grace_manager/settings.json and persists across sessions.

Configuration Files

File	Purpose
~/.grace_manager/profiles.json	Context blocks
~/.grace_manager/recent_projects.json	Recently opened projects
~/.grace_manager/settings.json	UI preferences (scaling, etc.)
~/.grace_manager/extension_presets.json	Saved extension presets
