Environment Configuration

The GPT CLI loads settings from two locations:

1. .env file in the current working directory (if present)
2. ~/.gpt-cli/.env (default persistent configuration)

You can configure model behavior, memory, logging, and streaming options.

Sample .env File

OPENAI_API_KEY=your-api-key-here
MODEL=gpt-4o
SUMMARY_MODEL=gpt-3.5-turbo
DEFAULT_PROMPT="You are a helpful assistant."
TEMPERATURE=0.7
MAX_TOKENS=4096

MEMORY_PATH=/custom/path/memory.json
HISTORY_PATH=/custom/path/history
MEMORY_LIMIT=10
MAX_SUMMARY_TOKENS=2048

LOG_FILE=/custom/path/gpt.log
LOG_LEVEL=INFO
LOG_TO_CONSOLE=true

MARKDOWN_ENABLED=true
STREAM_ENABLED=false

Use gpt --env to open and edit the .env file in your terminal editor.

Memory System

Memory includes:

• Rolling conversation summary
• The 10 most recent messages

Older messages are summarized once the limit is reached. Use --clear-memory to clear memory.

Troubleshooting

• Missing API key: Check .env for OPENAI_API_KEY
• Client init failed: Verify internet and credentials
• Token limit exceeded: Reduce input size or use summarization

Interactive Example Output

You: Tell me a joke about databases

Assistant: Why did the database break up with the spreadsheet?

Because it couldn't handle the rows of emotions.

Quickstart for Development

git clone https://github.com/BlackCortexAgent/blackcortex-gpt-cli.git
cd blackcortex-gpt-cli
make dev

Run tests:

make test       # uses virtualenv (.venv)
# or use 'make ci-release' if running outside .venv

Lint and format:

make lint
make format

Use make check to lint, test, build, and validate in .venv.
Use make ci-release for system Python (e.g., CI/CD pipelines).
