    student_id="jsmith",
    display_name="Jane Smith",
    cohort="F25-06623"
)

2. Run Discord Bot

export DISCORD_TOKEN="your-bot-token"
export API_SECRET="your-api-secret"
sbc bot run --port 5000

3. Discord Commands

Configuration

SBC uses a hierarchical configuration system:

1. Default values (built-in)
2. ~/.sbc.toml - User-level config
3. .sbc.toml - Project-level config
4. SBC_* environment variables

Generate a template:

sbc cfg init

Assignment Generation

Mark solution code in notebooks:

# Code cells
### BEGIN SOLUTION
answer = 42
### END SOLUTION

<!-- Markdown cells -->
<!-- BEGIN SOLUTION -->
The answer is 42.
<!-- END SOLUTION -->

Generate student version:

sbc assign assignment-01 --push

PDF Export Options

%pdf                  # Default: attach .ipynb, add header
%pdf report.pdf       # Custom filename
%pdf --no-attach      # Don't attach source notebook
%pdf --no-header      # Skip timestamp header
%pdf --no-save        # Don't auto-save before export
%pdf -v               # Verbose output

Semantic Search

Search across all course notebooks using ChromaDB for semantic similarity.

# Build the search index (one time)
%index

# Force rebuild the index
%index --rebuild

# Search for related content
%%search -n 5
What is a Gaussian process?

The search returns links to relevant notebook cells (markdown and code) ranked by semantic similarity to your query.

Development

# Install with dev dependencies
pip install -e ".[dev]"
# or with uv
uv pip install -e ".[dev]"

# Run tests
pytest

# Lint code
ruff check src/
