What it does

Codex Slides Deck is an agent skill from nexu-io/codex-slides. Compatibility entry point for scenario-led creation, Design Files, brand systems, inspecting, revising, restyling, and exporting Codex Slides slide decks. Use when a user asks Codex to make a presentation, use project files, edit an existing deck, manage slide structure, apply brand or template rules, or export PDF/PPTX.

Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Documents & Office, covering Slides and decks and PowerPoint presentations. It works with Microsoft PowerPoint. The repository describes itself as: 🎨 Open-source AI slide studio inside Codex: image-native decks, every slide a full visual canvas. ⚡ 10+ high-quality slides in ~4–5 minutes — Fast mode renders every page in… The licence is MIT.

When your agent uses it

  • A user asks Codex to make a presentation
  • Use project files
  • Edit an existing deck
  • Manage slide structure

Example prompts

  • “/codex-slides-deck”

What it can do on your machine

Read from SKILL.md and the folder at commit dbc2a59. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Codex Slides Deck loads about 972 tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 445 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~972

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Compatibility entry point for scenario-led creation, Design Files, brand systems, inspecting, revising, restyling, and exporting Codex Slides slide decks. Use when a user asks Codex to make a presentation, use project files, edit an existing deck, manage slide structure, apply brand or template rules, or export PDF/PPTX.

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.
