Codex Slides Deck

Codex Slides Deck

The canonical codex-slides sibling skill owns the complete workflow. Use the codex_slides MCP tools when available; otherwise run its self-contained CLI at ../codex-slides/scripts/codex-slides.mjs. Keep the live workspace available in the in-editor Browser whenever visual review helps.

Choose the flow

• Default to the live Browser workflow: open the Codex Slides home screen,

submit the request there, then operate the created project through clarify, outline confirmation, style selection, rendering, and review. Keep the Browser visible throughout.

• If Browser UI submission fails, use start_project / CLI start-project to

create the durable project shell, immediately open its returned URL, and continue in the UI.

• Use list_scenarios / CLI scenarios when a named workflow such as business

report, document-to-deck, data insights, brand application, localization, or batch generation fits. Upload required slot files and pass scenarioId, materialIds, and materialContexts into creation.

• Only when the user explicitly requests an unattended/headless one-call

result, call create_deck or CLI command create.

• For CLI automation or recovery, call create_outline, optionally

revise_outline and rank_inspiration, then render_deck; the CLI commands are outline, revise-outline, inspiration, and render.

• For an existing deck, use list_projects or get_project, then choose the

smallest mutation tool.

Edit with the right tool

• Use edit_deck for natural-language add/rewrite/redraw/optimize requests.
• Use manage_slide for deterministic add, duplicate, delete, or transition.
• Use regenerate_slide for one slide.
• Use restyle_deck for a whole-deck template/style change.
• Use upload_material before creation, editing, or restyling when a local

reference file matters.

• Use upload_slide_image for a finished PNG.
• Use mark_edit_slide when the user supplies an annotated PNG and wants a

clean revised slide.

• Use get_speaker_notes, update_speaker_notes, and

generate_speaker_notes (CLI speaker-notes with get, set, or generate) for presenter-only talk tracks. These notes persist per slide, appear in the speaker window, and are embedded in PPTX export.

• Use list_design_files, read_design_file, write_design_file, and

upload_design_file for the project file workspace. Pass selected paths as designFilePaths when revising an outline or editing a deck.

• Use get_brand_design_system then update_brand_design_system for persistent

project-wide brand/style rules. Redraw only when requested.

• Use start_project_run for navigation-independent chat, outline, or render

work; retain the returned runId and track or cancel it explicitly.

Show and verify

Open open_codex_slides / CLI open before a new creation and keep the live workspace visible. After a programmatic mutation, navigate or reload its resource link and inspect the changed slide or flow; do not make the user open the URL manually.

Follow the exact browserHandoff.url; it can focus the changed slide, speaker notes, export, versions, Design Files, brand system, Play menu, or durable run.

Use export_deck only after the requested visual result is ready. Browser-only controls such as Play from current/beginning, the synchronized audience and presenter windows, notes editing, slide navigation, and direct on-canvas marking remain available through the live workspace.
