open-press Create Slide

Create a slide deck as a sequence of direct, editable slide sources. Each slide owns its composition; the Press owns only deck registration, theme, and genuinely shared UI.

First principles

• Start with the audience, the single message of each slide, and the evidence that supports it.
• Keep one visual idea per slide. Prefer a diagram, image, comparison, or large number over dense prose.
• New slides begin as direct source files, never through a registry or preselected layout asset.
• Reuse a local component only after a visual primitive is genuinely repeated. Keep it in press/<slug>/ui/ or press/<slug>/components/.

Read before changing source

1. Read the deck press/<slug>/press.tsx, the active theme/default.css, and nearby slides.

2. State the deck's visual direction in a short STYLE note: type scale, palette, spacing, and intended visual language.

3. For a new or restructured deck, write a compact delivery shape:

   AUDIENCE: who must understand what
   STORY:
   - id | composition | one message | evidence or visual
   PRODUCE: direct slide sources, active theme, only proven shared UI
   

4. Preserve the existing slide order and IDs unless the user asks to change them.

Source contract

• press/<slug>/press.tsx registers slide IDs with marker-only <Slide id="…" /> entries.
• Each press/<slug>/slides/<id>/slide.tsx explicitly imports and composes the objects it needs.
• The deck canvas is fixed at 1920 × 1080. Keep a single <Slide> root, a predictable <Frame> boundary, and literal meta.
• layout in meta describes the composition for readers; it does not select source or generate a slide.
• Put deck tokens in press/<slug>/theme/default.css. Keep slide-specific CSS beside that slide or in the active theme when it is shared across the deck.
• Use @open-press/core objects where they clarify geometry, semantic structure, or responsive constraints. Use normal TSX and CSS for authored detail.

Read references/layout-contract.md before creating a slide. Read references/css-colocate.md when changing styles and references/press-tree.md when adding files.

Add and edit slides

Create a blank slide source with:

open-press slide add <id> --press <slug>

Then edit press/<slug>/slides/<id>/slide.tsx directly. The generated placeholder is intentionally minimal: replace it with the slide's actual composition rather than preserving boilerplate.

For a new visual treatment:

1. Build the composition in the slide source.
2. Extract a local primitive only after the same structure has a second real use.
3. Name shared components for their role (EvidenceGrid, SectionKicker), not for a generic layout category.
4. Keep the content and metadata literal enough for source inspection and reader navigation.

Reordering and removal

Use the CLI to preserve registration and folder consistency:

open-press slide move <id> <position> --press <slug>
open-press slide remove <id> --press <slug>
open-press slide status --press <slug>

Review checklist

• Does every slide communicate one claim at speaking pace?
• Are images, charts, and diagrams legible at presentation distance?
• Is the slide source self-contained and directly editable?
• Are shared components justified by real reuse rather than anticipated reuse?
• Does the active theme provide the spacing and contrast the deck needs?
• Do navigation, slide order, notes, source view, and focus state still behave correctly?

Verify source changes with:

npm run typecheck
npm test
npm run build

For visual work, also run npm run dev:workspace and inspect the affected Press in the Workbench before reporting completion.
