Beautiful.ai

WORKING SLICE
Turn a reviewed outline into slides using a small library of title, comparison, quote and image layouts. Enforce text-fit warnings, allow manual adjustment and export a faithful PDF before attempting editable PPTX.

Build this scoped Beautiful.ai-inspired workflow with a documented data model and visible failure states.

Architecture
- Vite, React and TypeScript with SVG for diagrams or a Canvas rendering adapter for raster assets.
- IndexedDB for projects and revisions; versioned JSON documents with stable object IDs.

Prerequisites and limits
A supported Node release for development and a modern browser. Ship a static bundle that can work locally without an account.
Outside this release: smart templates; brand controls

Data model and correctness
decks, ordered slides, constrained layout types, text boxes, image crops and theme tokens
Invariant: Content overflow is shown, never silently clipped or shrunk to unreadable text; imported text is not assumed to be fact-checked.
Represent edits as reversible commands, debounce autosave, and persist a complete project snapshot before destructive structural changes.

Security and privacy
Sanitize imported SVG, reject external scripts and oversized assets, and require user selection before reading local files. Keep document contents out of telemetry.

Recovery and export
Export editable JSON with assets and an SVG or PNG rendering. Reopen the editable export to retain layers, relationships and IDs; image exports alone are not backups.

Implementation order
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Turn a reviewed outline into slides using a small library of title, comparison, quote and image layouts. Enforce text-fit warnings, allow manual adjustment and export a faithful PDF before attempting editable PPTX. Record prerequisites, select representative user-owned fixtures and document the unsupported features: smart templates; brand controls
2. Phase 2 — Durable model. Model decks, ordered slides, constrained layout types, text boxes, image crops and theme tokens Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Content overflow is shown, never silently clipped or shrunk to unreadable text; imported text is not assumed to be fact-checked.
3. Phase 3 — Complete the first useful path. Implement the workflow's input, review and output interface, with clear controls and explicit empty/error states. Represent edits as reversible commands, debounce autosave, and persist a complete project snapshot before destructive structural changes.
4. Phase 4 — Permissions and integration failure. Sanitize imported SVG, reject external scripts and oversized assets, and require user selection before reading local files. Keep document contents out of telemetry. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
5. Phase 5 — Portable handoff. Export editable JSON with assets and an SVG or PNG rendering. Reopen the editable export to retain layers, relationships and IDs; image exports alone are not backups. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
6. Phase 6 — Acceptance scenarios. A long comparison heading produces a visible overflow warning; a PDF export has the same slide order and no missing fonts or images. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

Acceptance
A long comparison heading produces a visible overflow warning; a PDF export has the same slide order and no missing fonts or images.
Use real source data or clearly labeled fixtures. Explain unsupported input and provider failures; do not fabricate analytics, delivery receipts, accuracy claims or security guarantees.

# AGENTS.md — Build guide for Beautiful.ai

## Project scope
Turn a reviewed outline into slides using a small library of title, comparison, quote and image layouts. Enforce text-fit warnings, allow manual adjustment and export a faithful PDF before attempting editable PPTX.

Catalogue verdict: kinda. You can build a template deck generator, but auto-layout slide behavior, template polish, brand controls, PowerPoint import/export, and collaboration are real work.
Use the implementation prompt below to define the deliverable. Complete each phase's acceptance checks before extending the scope.

## Working agreement
- Inspect the repository and its existing instructions before choosing paths, dependencies or commands. Keep one coherent stack and explain changes to the proposed architecture.
- Plan a vertical slice that accepts a real input and produces the useful output described below. Persist only the state the prompt calls for; respect memory-only and upstream-managed workflows. Use fixtures only when they are clearly labelled.
- After scaffolding, document the actual install, development, check and build commands in README and keep them synchronized with the package or project manifest. Do not report commands as successful unless they ran.
- Work in small steps. At handoff, list implemented flows, checks actually performed, remaining blockers, and any credentials or provider setup the owner must supply.
- Do not publish, spend money, contact customers, delete source data or run irreversible migrations without the project owner's authorization.

## Prerequisites
- A supported Node release for development and a modern browser. Ship a static bundle that can work locally without an account.
- Implementation components: Vite, React and TypeScript with SVG for diagrams or a Canvas rendering adapter for raster assets. IndexedDB for projects and revisions; versioned JSON documents with stable object IDs.
- Scope boundary: smart templates; brand controls

Read the linked SKILL.md and its dependencies before adding a skill. Select only the skills matching this project's runtime and task; their documentation does not supply API access, credentials or approval to perform external actions. Pin the reviewed revision where the tool supports it. Follow the chosen agent's documented project-level installation mechanism.

## Distribution ideas
These are optional planning notes. Obtain the owner's approval before publishing or contacting anyone.
- Demonstrate the actual Beautiful.ai-inspired workflow with owned or clearly labeled sample data: Turn a reviewed outline into slides using a small library of title, comparison, quote and image layouts. Enforce text-fit warnings, allow manual adjustment and export a faithful PDF before attempting editable PPTX.
- Publish a reproducible walkthrough with this observable result: A long comparison heading produces a visible overflow warning; a PDF export has the same slide order and no missing fonts or images.
- Explain who can operate this scoped tool, its setup and ongoing costs, and these remaining product gaps: smart templates; brand controls Avoid guaranteed savings, performance scores or implied endorsement.

## Completion evidence
Demonstrate the prompt's acceptance scenarios against the scoped workflow. Include setup from a clean checkout and failure recovery. Check persistence across restart and export/restore only for the state the prompt says to store; for memory-only tools, confirm that temporary content is discarded as specified. Record actual results and remaining limitations. A detailed plan alone does not establish a working replacement.
