@gistdiff/core

Core library powering the gistdiff CLI. Summarizes a git diff into a commit message via the Vercel AI Gateway.

Most users want the CLI, not this package — install gistdiff instead:

npm i -g gistdiff

Programmatic use

import { summarizeDiff, DEFAULT_MODEL } from "@gistdiff/core";

const result = await summarizeDiff(diffText, {
  model: DEFAULT_MODEL,
  description: true,
  reasoning: true,
});

console.log(result.subject);
console.log(result.body);
console.log(result.cost); // usage + authoritative billing from the gateway

Requires AI_GATEWAY_API_KEY in the environment. Node.js 20+.
