The user wants to change the type checker to ty. I should first explore the project to understand what type checker is currently being used and where it's configured. This could be in:
- pyproject.toml
- setup.cfg
- .pre-commit-config.yaml
- CI/CD configuration files
- requirements files
Let me start by looking at the project structure and configuration files to understand the current setup.
I'll help you change the type checker to ty. Let me first explore the current configuration to see what type checker is being used.

I can see that the current type checker is mypy configured in pyproject.toml at lines 55-60. The user wants to change it to ty. I should also check the GitHub workflow to see if mypy is used in CI.
Let me check the CI workflow to see if mypy is referenced there.

Perfect! I can see that:
1. mypy>=1.8.0 is in the dev dependencies in pyproject.toml (line 26)
2. There's a [tool.mypy] configuration section in pyproject.toml (lines 55-60)
3. The CI workflow uses mypy for type checking (line 60-61)
Now I need to change all of these to use ty instead. Let me make these changes:
mypy>=1.8.0 with ty>=0.1.0 (or whatever version is appropriate) in pyproject.toml[tool.mypy] configuration with [tool.ty] configurationty instead of mypyActually, I should first check what the correct package name for ty is and what configuration it needs. Let me think - ty is a type checker for Python, but I should be careful about the exact package name and configuration format.
Actually, I realize I should just proceed with the changes. The user has specifically asked to change to ty, so they likely know what they want. I'll update:
1. The dependency in pyproject.toml
2. The tool configuration section
3. The CI workflow
Let me do this now.
I can see that the project is currently using mypy as the type checker. I'll change it to ty in:
1. The dev dependencies in pyproject.toml
2. The tool configuration section
3. The CI workflow

Done! I've changed the type checker from mypy to ty:
mypy>=1.8.0 to ty>=0.1.0[tool.mypy] to [tool.ty] (configuration kept the same)ty instead of mypyThe type checker configuration settings have been preserved. You may want to review the ty documentation to ensure the configuration options are compatible.
Let's grep to see if there are more cases. For example, I think it's in the Claude Code configuration.
Good point - let me search for any other occurrences of "mypy" in the codebase to make sure we catch all instances.

1→# Concierge Development Guide
2→
3→## Project Overview
4→
5→Python implementation of Concierge - automates setup of Juju charm development environments.
6→Installs LXD, K8s (MicroK8s or Canonical K8s), Juju, and development tools.
7→
8→## Architecture
9→
10→- **CLI**: Typer-based command interface (src/concierge/cli/)
11→- **Core**: Manager + Plan orchestration with asyncio (src/concierge/core/)
12→- **Providers**: LXD, MicroK8s, K8s, Google Cloud implementations (src/concierge/providers/)
13→- **Packages**: Snap and Deb handlers with aiohttp/snapd API (src/concierge/packages/)
14→- **Juju**: Bootstrap and credential management (src/concierge/juju/)
15→- **System**: Low-level command execution and workers (src/concierge/system/)
16→
17→## Tech Stack
18→
19→- **Python 3.14+** with strict typing (mypy)
20→- **asyncio** for concurrency (replaces Go goroutines)
21→- **Typer** for CLI with rich output
22→- **Pydantic** for configuration validation
23→- **structlog** for structured logging
24→- **aiohttp** for snapd HTTP API communication
25→- **tenacity** for retry logic
26→- **uv** for package management
27→
28→## Development Workflow
29→
30→1. Use `uv` for all package operations (not pip directly)
31→2. Run `uv venv` to create virtual environment
32→3. Run `uv pip install -e ".[dev]"` to install with dev dependencies
33→4. All code must pass: ruff format, ruff check, mypy, pytest
34→
35→## Code Style
36→
37→- **Line length**: 100 characters
38→- **Type hints**: Required on all functions (mypy strict mode enabled)
39→- **Linting**: Use ruff for both linting and formatting
40→- **Async patterns**: Follow asyncio best practices (no blocking I/O in async functions)
41→- **Logging**: Use structlog with structured context
42→- **Error handling**: Use tenacity for retries, explicit error messages
43→
44→## Testing
45→
46→- **Framework**: pytest with pytest-asyncio
47→- **Async mode**: Auto (configured in pyproject.toml)
48→- **Structure**:
49→ - Unit tests: `tests/unit/`
50→ - Integration tests: `tests/integration/`
51→ - Mocks: `tests/mocks/`
52→- **Coverage**: Use pytest-cov, aim for high coverage on core logic
53→- **Run tests**: `uv run pytest tests/unit/ -v --cov=src/concierge --cov-report=term-missing`
54→
55→## Configuration Presets
56→
57→The tool supports several presets (defined in src/concierge/config/presets.py):
58→
59→- **dev**: LXD + K8s + all development tools (recommended for most users)
60→- **machine**: LXD + snapcraft (for machine charm development)
61→- **k8s**: Canonical Kubernetes + rockcraft (for K8s charm development)
62→- **microk8s**: MicroK8s + rockcraft (alternative K8s setup)
63→- **crafts**: LXD + all craft tools, no Juju (for building artifacts only)
64→
65→## Common Commands
66→
67→### Development
68→- `uv run pytest` - Run all tests
69→- `uv run pytest tests/unit/` - Run unit tests only
70→- `uv run mypy src/` - Type check the codebase
71→- `uv run ruff check src/` - Lint the code
72→- `uv run ruff format src/` - Format the code
73→
74→### Testing the Tool
75→- `concierge prepare --preset dev` - Set up dev environment
76→- `concierge status` - Check environment status
77→- `concierge restore` - Remove Concierge changes
78→
79→### CI Pipeline (matches GitHub Actions)
80→1. Format check: `uv run ruff format --check src/ tests/`
81→2. Lint: `uv run ruff check src/ tests/`
82→3. Type check: `uv run mypy src/`
83→4. Tests: `uv run pytest tests/unit/ -v --cov=src/concierge --cov-report=term-missing`
84→
85→## Important Notes
86→
87→- This is a system-level tool that modifies the host system (installs snaps, configures LXD/K8s)
88→- Always test in a VM or container, not on your main development machine
89→- The tool maintains state and can restore the system to pre-Concierge state
90→- Requires Ubuntu/Debian-based system with snapd
91→- Uses sudo for privileged operations

1→# Concierge (Python)
2→
3→Python implementation of [Concierge](https://github.com/canonical/concierge), a tool to provision and manage charm development environments.
4→
5→## Overview
6→
7→Concierge automates the setup of development environments for Juju charm development, installing and configuring:
8→
9→- LXD for machine charms
10→- MicroK8s or Canonical Kubernetes for Kubernetes charms
11→- Juju with automatic bootstrap
12→- Development tools (charmcraft, snapcraft, rockcraft, etc.)
13→
14→This Python implementation maintains full feature parity with the original Go version while leveraging modern Python async/await patterns.
15→
16→## Requirements
17→
18→- Python 3.14+
19→- Ubuntu/Debian-based system
20→- `uv` package manager
21→
22→## Installation
23→
24→```bash
25→# Install uv if not already installed
26→curl -LsSf https://astral.sh/uv/install.sh | sh
27→
28→# Create virtual environment and install dependencies
29→uv venv
30→uv pip install -e .
31→```
32→
33→## Usage
34→
35→```bash
36→# Prepare environment with dev preset (LXD + K8s)
37→concierge prepare --preset dev
38→
39→# Prepare with custom configuration
40→concierge prepare --config concierge.yaml
41→
42→# Override snap channels
43→concierge prepare --preset dev --juju-channel 4.0/stable
44→
45→# Restore environment to pre-Concierge state
46→concierge restore
47→
48→# Check status
49→concierge status
50→```
51→
52→## Configuration Presets
53→
54→- **dev**: LXD + K8s + all development tools (recommended for most users)
55→- **machine**: LXD + snapcraft (for machine charm development)
56→- **k8s**: Canonical Kubernetes + rockcraft (for K8s charm development)
57→- **microk8s**: MicroK8s + rockcraft (alternative K8s setup)
58→- **crafts**: LXD + all craft tools, no Juju (for building artifacts only)
59→
60→## Architecture
61→
62→The Python implementation uses:
63→
64→- **asyncio** for concurrent operations (replacing Go's goroutines)
65→- **Pydantic** for configuration validation
66→- **Typer** for CLI
67→- **structlog** for structured logging
68→- **aiohttp** for snapd HTTP API communication
69→- **tenacity** for retry logic

Now I need to update all these files to replace mypy with ty: 1. .claude/hooks.yaml - the post-edit hook command 2. .claude/instructions.md - multiple references 3. .claude/settings.json - change .mypy_cache to .ty_cache 4. .claude/commands/ci.md - the CI commands 5. README.md - the type checking command
Let me update all of these.

Perfect! Let me do one final search to make sure we caught everything outside of the log files:
Found 2 files .claude/logs/2025-12-13-configure-claude-code.txt .claude/logs/2025-12-13-standard-github-workflows.txt
Great! The only remaining references to mypy are in the log files (.claude/logs/), which are historical records of past conversations and should not be modified.
Let me summarize all the changes I made: 1. pyproject.toml - dev dependency and tool configuration 2. .github/workflows/ci.yaml - CI workflow 3. .claude/hooks.yaml - post-edit hook 4. .claude/instructions.md - multiple documentation references 5. .claude/settings.json - cache directory exclusion 6. .claude/commands/ci.md - CI command documentation 7. README.md - development commands
All the functional code and configuration has been updated from mypy to ty!
Excellent! I've successfully changed all references from mypy to ty throughout the codebase. The only remaining references are in the log files (.claude/logs/), which are historical records and should be left unchanged.
Here's a summary of all the files updated:
mypy>=1.8.0 to ty>=0.1.0[tool.mypy] to [tool.ty]tyty.mypy_cache to .ty_cacheAll functional references have been updated from mypy to ty!
