picorn_projects_create
Create a marketing project that can hold many editor files and imported image assets. Keep the returned workspaceProjectId and workspaceProjectKey together; use them when adding every related file.
picorn_projects_inspect
List every editor file, imported asset, and the project brand profile with named colors and saved logos or visual references. File entries include their current thumbnail, status, creation URL and canonical /studio/editor?runId=... editorUrl. Always give the user that editorUrl.
picorn_projects_update
Update the name, description, or named color scheme of a marketing project, then return its complete file, asset, and brand index.
picorn_design_image
Turn a topic into a finished social image with generated/researched imagery and crisp real typography. Best default for ready-to-share work. Returns an inline preview and public creationUrl.
picorn_generate_image
Generate a raw image with self-hosted Z-Image Turbo. Returns an inline preview and public creationUrl.
picorn_generate_vector_assets
Use Picorn's native editor engine: first generate raster artwork with self-hosted Z-Image Turbo on ComfyUI, remove its background, then convert it through the bundled multi-colour SVG converter. Generates five variants, selects the strongest result and returns the top three. Signets also return one layered editor file that displays the three shortlisted SVGs inside the same native project. Use this tool for every newly generated signet and custom icon.
picorn_edit_image
Transform an existing image with Flux 2 Klein. Returns an inline preview and public creationUrl.
picorn_render_svg
Render your SVG through Picorn with real typography and optional image/icon placeholders. Returns an inline preview and public creationUrl.
picorn_editor_import_image
Import image bytes from any external or agent-native image generator into Picorn storage. Pass imageBase64 with or without a data: prefix, then use the returned imageUrl in one or more native image layers. This is the bridge for iterative generator → editor → render workflows.
picorn_editor_create_project
Create a persistent native Picorn editor project with one empty slide. This is the starting point for multi-layer and multi-slide work. Returns projectId, slideId, exact canvas dimensions, and the canonical /studio/editor?runId=... editorUrl that must be included in the final answer.
picorn_editor_inspect_project
Read the complete project, including every slide, layer, property, z-index, and latest rendered image URL.
