Script Writer workspace

Use the existing Narrative Compiler as a typed, versioned production Block.

Script Writer (sm.script@1.1.0) reuses the full Narrative Compiler: reference transcripts, writing and optional research, review, inline edits, revision chat, saved scripts, learned voices, and version history. Open its listing in Marketplace or the Block library, then choose Use in studio → Open workspace. It is no longer an account-menu utility. Starting Chat remains separate and protected.

The manifest and adapter are in packages/block-platform/script-writer.js. They use the same SDK validateValues and resolveContextInputs contract as other Blocks. client/src/components/ScriptWriterBlock.jsx mounts the existing UI.

• Primary input: optional brief document (schemaVersion 1) with production

planning context. The app supplies the project title and conversation. A Step can prefill the topic with config.input: {schemaVersion: 1, topic: "Your topic"}.

• Secondary script: optional script document from context.script.read,

containing {schemaVersion: 1, text: "Current narration"}.

• Primary output: script, semantic role narration_script, containing

{schemaVersion: 1, text: "Accepted narration"}. Empty scripts, non-text values, and text over 200,000 characters are rejected.

Use this script validates the output and updates the shared project narration. The recommended workflow is Script Writer → Voiceover; its compatible typed connection is implemented through the shared narration document, without graph nodes or wires. Opening the Block does not generate a script or charge credits. Existing writing and research actions retain their displayed prices and server billing checks. A viewer cannot write; accepting a stale draft cannot overwrite a teammate's changed narration.

The version-addressed source download includes the current wrapper, Narrative Compiler, local source dependencies, and this SDK. This is a trusted built-in host workspace, not an arbitrary React package admitted by the external sandbox. External imports still support recipe and isolated JavaScript runtimes; changing an imported manifest to runtime: host cannot load privileged workspace code.
