+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+`cull-gmail` is a Rust-based Gmail management library and CLI tool that enables automated email culling operations through the Gmail API. It supports message querying, filtering, batch operations (trash/delete), and rule-based retention policies.
+
+## Development Commands
+
+```bash
+# Build the project
+cargo build
+
+# Run all tests
+cargo test
+
+# Run specific test file
+cargo test --test gmail_client_unit_tests
+
+# Run ignored integration tests (Gmail API integration)
+cargo test --test gmail_message_list_integration -- --ignored
+
+# Format code
+cargo fmt
+
+# Run linter
+cargo clippy
+
+# Check for security vulnerabilities
+cargo audit
+```

+
+### Key Components
+
+**GmailClient** (`gmail_client.rs`): Main client for Gmail API interactions. Handles authentication, message querying, and batch operations.
+
+**Rules** (`rules.rs`): Configuration for automated retention policies with validation and execution.
+
+**Retention** (`retention.rs`): Defines message age-based retention policies (e.g., "older_than:1y").
+
+**RuleProcessor** (`rule_processor.rs`): Executes rules against message lists, applying appropriate actions.
+
+**ClientConfig** (`client_config.rs`): Manages OAuth2 credentials and configuration file parsing.
+
+**CLI** (`cli/`): Command-line interface with clap-based argument parsing.
+
+## Gmail API Integration
+
+- Uses `google-gmail1` crate (version 7.0.0) with `yup-oauth2` and `aws-lc-rs` features
+- OAuth2 authentication with token caching in `~/.cull-gmail/gmail1/`
+- Default page size: 200 messages (configurable via `DEFAULT_MAX_RESULTS`)
+- Supports Gmail search syntax for queries
+
+## Testing
+
+- Unit tests: `cargo test`
+- Integration tests: Located in `crates/cull-gmail/tests/`
+- Gmail API integration tests are ignored by default (`#[ignore]`) and require `--ignored` flag
+- Mock tests available in test suite for unit testing
+
+## Configuration
+
+- Default config path: `~/.cull-gmail/cull-gmail.toml`
+- OAuth2 credential file path: `~/.cull-gmail/client_secret.json`
+- Rules file: `~/.cull-gmail/rules.toml`
+- Environment variables override config settings (e.g., `APP_CREDENTIAL_FILE`)
+
+## Error Handling
+
+The library uses a custom `Error` type with variants for:
+- `NoLabelsFound`: Mailbox has no labels
+- `LabelNotFoundInMailbox(String)`: Specific label not found
+- `RuleNotFound(usize)`: Rule ID doesn't exist
+- `GoogleGmail1(Box<google_gmail1::Error>)`: Gmail API errors
+- `StdIO(std::io::Error)`: File I/O errors
+- `Config(config::ConfigError)`: Configuration errors
+
+## Logging
+
+- Uses `log` crate with `env_logger`
+- Verbosity controlled via CLI flags (`-v`, `-vv`, `-vvv`) and `RUST_LOG` environment variable
+- Log levels: error, warn, info, debug, trace
+
+## Code Style
+
+- Rust edition 2024
+- Minimum Rust version: 1.88
+- Clippy lints configured in workspace
+- Follows official Rust style guide
+- Use `cargo fmt` for formatting
+- Use `cargo clippy` for linting
