# Copy this file into .github/workflows/ in your project to publish a
# code-graph snapshot alongside each GitHub release. The snapshot is a
# small (~3-5MB) zstd-compressed SQLite database that lets first-time
# clones of your repo skip the initial full code-graph index.
#
# Requires: code-graph-mcp >= 0.23.0 published to npm.
