+# Agent Guidelines for my-log
+
+## Build/Test/Lint Commands
+- Build: `make build` or `go build -o my-log`
+- Test all: `make test` (runs fmt + test with race + coverage)
+- Test single: `go test ./path/to/package -run TestName`
+- Format: `make fmt` or `go fmt ./...`
+- Coverage report: `make report` (generates cover.html)
+
+## Code Style
+- **Module**: `codeberg.org/danjones000/my-log`
+- **Go version**: 1.21.5
+- **Imports**: Standard library first, then external packages, then local packages. Use short aliases for common imports (e.g., `fp` for `path/filepath`, `mapst` for `mitchellh/mapstructure`)
+- **Formatting**: Always run `go fmt` before commits (included in test target)
+- **Types**: Use explicit types (e.g., `int64`, `float64`). Convert numbers appropriately when unmarshaling JSON
+- **Naming**: PascalCase for exported, camelCase for unexported. Use descriptive names
+- **Error handling**: Return wrapped errors with context. Define custom errors in models/errors.go. Use `ErrorIs` for error checking
+- **Testing**: Use testify/assert. Table-driven tests with helper functions. Test both marshal/unmarshal for encoding types
+- **Concurrency**: Use channels and goroutines with WaitGroups for parallel processing (see entry.go patterns)
+- **Comments**: Include license header on cmd files. Document exported functions and types
+
+## Git Commit Guidelines
+- **Format**: Prepend commit messages with a gitmoji emoji (see https://gitmoji.dev)
+- **Style**: Write detailed commit messages that explain what changed and why
+- **Examples**: `✨ Add JSON export functionality for log entries`, `🐛 Fix date parsing for RFC3339 timestamps`, `📝 Update README with configuration examples`
+
+## Git Flow Workflow
+- **Main branches**: `stable` (production-ready), `develop` (integration branch)
+- **Development**: Always commit new features/fixes to `develop` branch or appropriate feature branches
+- **Branch prefixes**:
+  - `feat/feature-name` - New features, merge to `develop` when complete
+  - `bug/bug-name` - Bug fixes (non-urgent), merge to `develop` when complete
+  - `hot/version` - Hotfixes for production issues, merge to **both** `stable` and `develop`
+  - `rel/version` - Release preparation branches
+- **Version tags**: Prefix all version tags with `v` (e.g., `v1.0.2`, `v0.0.6`)
+- **Releases**: Update CHANGELOG.md with a summary of changes for each new version
+- **Never commit directly to**: `stable` branch (only merge from `rel/` or `hot/` branches)
+- **Before starting work**: Ensure you're on `develop` branch or create an appropriate feature branch from it
+
+## Project Structure
+- `cmd/my-log/`: Main application entrypoint
+- `internal/cmd/`: Cobra commands (root, drop, config)
+- `models/`: Core types (Entry, Log, Meta) with marshal/unmarshal implementations
+- `config/`: TOML-based configuration with env overrides
+- `formatters/`: Output formatters (plain, json, null)
+- `files/`: File operations (append)
+- `tools/`: Utilities (date parsing, string parsing, write buffers)
