What is codex-slides-deck?

A workflow for creating, inspecting, revising, styling, and exporting Codex Slides presentations. It supports scenario-based work, design files, brand rules, and visual review in the editor.

Use it to make or edit presentations, apply templates or brand guidance, work with project files, inspect slide structure, and export a reviewed deck.

It provides one process for managing a deck from its initial request through review and export, including when the request is ambiguous or uses source files.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00076	$0.00902
Opus 5.5	$0.00030	$0.00361
Sonnet 5.5	$0.00015	$0.00180
Haiku 4.5	$0.00008	$0.00090

Security

Grade A, and why

codex-slides-deck scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
