Deployment CLI Tools

Environment

• Activate conda activate ch before any backend command.
• Use pip (inside ch) for backend dependencies; Yarn for any frontend work.

Key Scripts

• harness-generate — generate code
• harness-deployment — generate deployment files (Helm charts, CI/CD files, etc.)
• harness-application — generate application code (e.g. Django apps)
• harness-migrate — migration helper
• ch_cli_tools — Python package for deployment and other tools
• tests/ — unit test utilities

Code Style

Follow the project-wide style in the root CLAUDE.md. Key points for this package:

• Keep architecture lean — avoid unnecessary layers and abstractions.
• Utils: stateless pure functions, no ORM or external data sources.
• Helpers: stateless business logic pieces.
• Services: business workflows and cross-model coordination.
• Bubble exceptions up; never swallow them silently in helpers or services.
• Cover critical logic with unit tests using mocks to isolate units.

Constraints

• Never start development servers.
• Never create documentation files unless explicitly asked.
• Always use pip inside ch conda env; never use npm.
