# Agent Instructions: PhotoTools3
|
|
|
|
## Environment Setup
|
|
Requires a `.env` file with the following variables:
|
|
- `llm_api_key`: API key for the LLM provider.
|
|
- `llm_api_base_url`: Base URL for the LLM API.
|
|
- `llm_default_temperature`: Float value for temperature.
|
|
|
|
## System Dependencies
|
|
- `exiftool` binary: required by `pyexiftool` at runtime, not installable via pip/uv.
|
|
- Arch: `perl-image-exiftool`
|
|
- Debian/Ubuntu: `libimage-exiftool-perl`
|
|
|
|
## Development Toolchain
|
|
- **Dependency Management**: Use `uv`.
|
|
- **Python Version**: Requires Python `>=3.14`.
|
|
- **Testing**: Run `pytest` to execute the test suite in `test/`.
|
|
- **Linting & Formatting**: Use `ruff` and `black`.
|
|
|
|
## CLI Usage
|
|
The primary entry point is the `photools3` command:
|
|
- `photools3 keywords <image_path>`: Extracts keywords and captions from a single image.
|
|
|
|
## Architecture & Logic
|
|
- **`src/photools3/photo.py`**: Core image processing logic, including resizing, RGB conversion, and generating base64 JPEG encodings specifically for LLM vision compatibility.
|
|
- **`src/photools3/llm_session.py`**: Manages the workflow of sending processed images to the LLM and parsing results.
|
|
- **Configuration**: The list of keywords to extract is maintained in `config/keywords.txt`.
