Anthropic API key
Run SVN AI: Set Anthropic API Key . The key is stored in VS Code Secret Storage. To remove it, run SVN AI: Clear Anthropic API Key .
How it works
Shells out to svn diff --internal-diff (streams stdout, hard-capped by maxDiffBytes).
Splits the diff per file (Index: boundary), classifies each as text / binary / property-only / generated.
Routes:
Total tokens under singleCallThresholdTokens → one call to the smart model with the full diff.
Otherwise → fast model summarizes each text file in parallel, smart model aggregates.
Final smart-model call streams into the SCM input box.
Troubleshooting
"svn CLI not found" — Install Subversion and make sure svn is on your PATH."No AI provider available" — Install GitHub Copilot or set an Anthropic API key.No sparkle button — Make sure johnstoncode.svn-scm is installed and the workspace folder is an SVN working copy.First Copilot call blocked — Accept the Copilot Language Model consent dialog when prompted, then retry.
Out of scope (v0.1)
Per-changelist messages, pre-commit hooks, multi-repo per-repo config, real tokenizers, cross-session caching, other SCMs.
