Inspect the existing repository before changing anything. +2. Preserve existing user changes. +3. Never delete or overwrite files without checking their purpose. +4. Never commit secrets, API keys, passwords, tokens, private keys, `.env` files, or personal data. +5. Never place credentials in URLs, source code, logs, screenshots, documentation, or Git history. +6. Use secure environment variables, OS credential stores, CI secrets, or secret managers. +7. Prefer simple, typed, testable, modular code. +8. Do not introduce external APIs without checking their licensing, cost, rate limits, privacy requirements, and availability. +9. Do not scrape websites without explicit permission. +10. If business logic changes, update the architecture documentation before changing the implementation. + +## Planning workflow + +Before implementation: + +1. Inspect the repository and current Git status. +2. Create or update: + - `PROJECT_MAP.md` + - `architecture/` + - `Manual.md` + - `CHANGELOG.md` + - `VERSION` + - `.gitignore` +3. Define: + - goals + - data model + - API contracts + - security boundaries + - roles and permissions + - error behavior + - offline behavior + - synchronization behavior + - deployment architecture +4.
