+# Agent instructions
+## Git Commit Style
+- Make small, focused commits while working
+- Commit changes incrementally to make history easier to follow
+- Write clear, concise commit messages describing what changed
+- Ask permission before commiting or merging to main branch
+- When applicable, write tests before implementation
+
+# Developer Commands
+
+```bash
+# Unit tests (fast, no database required)
+cargo test --lib
+
+# Integration tests (requires test DB - run setup first)
+cargo run -- db setup --env test
+cargo test --tests
+
+# Single test file
+cargo test --test config_test
+
+# CLI commands
+cargo run -- db setup --env <dev|test|prod>
+cargo run -- db reset --env <dev|test|prod>
+cargo run -- import <csv-file> --env <dev|test|prod>
+cargo run -- generate <csv-file> <output-dir>
+```
+
+# Config Loading
+
+- Files: `config.toml` → `config.<env>.toml` → `config.example.toml` (fallback)
+- Gitignored: `config.toml`, `config.dev.toml`, `config.test.toml`, `config.prod.toml`
+- DB names: `rusty_petroleum_dev`, `rusty_petroleum_test`, `rusty_petroleum_prod`
+
+# Architecture
+
+- Binary: `src/main.rs`, Library: `src/lib.rs`
+- Test entry: `tests/common/test_db.rs` creates fresh DB per test via `cargo test --test`
+- Run lib tests first to verify logic without DB dependency
+
+# Issue Management
+
+- Use Gitea REST API to close issues:
+  ```bash
+  curl -X PATCH https://gitea.rowanbrook.net/api/v1/repos/jakob/rusty-petroleum/issues/{issue_number} \
+    -H "Content-Type: application/json" \
+    -H "Authorization: Bearer YOUR_TOKEN" \
+    -d '{"state": "closed"}'
+  ```
