Official extensions for rill. Each extension is an independent npm package under @rcrsr/.

All packages are published under @rcrsr/ on npm. Provider categories (LLM, Key-Value, Filesystem, Vector DB) share function signatures within their category and are interchangeable. Standalone and Integrations expose distinct host functions.

All extensions follow the same factory pattern:

import { createRuntimeContext, prefixFunctions } from '@rcrsr/rill';
import { createAnthropicExtension } from '@rcrsr/rill-ext-anthropic';

const ext = createAnthropicExtension({
  api_key: process.env.ANTHROPIC_API_KEY,
  model: 'claude-sonnet-4-20250514',
});

const { dispose, ...functions } = prefixFunctions('llm', ext);
const ctx = createRuntimeContext({ functions });

// ... execute scripts ...

await dispose();

Extensions in the same category share function signatures. Swap providers with no script changes.

Extensions match the minor version of @rcrsr/rill. Any extension at 0.4.x works with rill@0.4.y. Each extension change bumps the patch version independently.
