SillyTavern Extension Builder

Overview

Create production-ready SillyTavern third-party extensions with the documented extension APIs and packaging rules.

Workflow

1. Define the extension contract.

• Confirm extension slug, display name, minimum supported SillyTavern version, required modules, and whether the feature is UI-only, slash-command-only, or background worker based.
• If the user does not provide a slug, generate a lowercase kebab-case slug.

1. Scaffold baseline files.

• Prefer scripts/scaffold_extension.sh to generate manifest.json, index.js, style.css, and settings.html.
• Choose template mode:

- default for UI/event-focused extensions. - slash for slash-command-first extensions.

• If the user already has files, perform minimal edits instead of full rewrites.

1. Wire extension lifecycle and settings.

• Keep extension settings under extension_settings[EXTENSION_NAME].
• Call loadExtensionSettings(EXTENSION_NAME) before reading setting values.
• Use saveSettingsDebounced() after setting changes.
• Register startup/event handlers inside jQuery(async () => {...}).

1. Implement user-facing behavior.

• For DOM/UI integration, use documented APIs (context helpers, templates, settings rendering).
• For command behavior, add slash commands and argument parsing with the slash-command APIs when needed.
• For background logic, use a module worker class and gate execution by current chat context.

1. Validate compatibility and packaging.

• Ensure manifest keys are correct and file names match actual files.
• Ensure import paths are valid from the extension directory.
• Keep third-party dependency usage explicit and minimal.
• Package as a repo or zip with only required runtime files.

1. Return deliverables.

• Provide final file set and a concise integration note.
• Include install path expectations and any required module prerequisites.

Output Rules

• Prefer minimal-diff changes when editing an existing extension.
• Keep settings schema stable; migrate old keys instead of silently breaking them.
• Use deterministic IDs/command names (derive from extension slug).
• If introducing a slash command, include help text and argument validation.
• If introducing a module worker, include clear stop conditions for idle/no-chat states.

Notes

• The docs and extension APIs evolve. If behavior is uncertain, prefer upstream docs over assumptions and keep code conservative.
• Keep code style aligned with existing SillyTavern extension conventions (imports, settings handling, and event registration).
