Specification — Hero App for Slide & Website Generation

1. Purpose

This application is a Rust-first automation workspace for creating:

  1. Slides
  2. Websites

The system follows internal Hero best practices and integrates with (as skills):

  • /hero_proc_log for structured logging
  • /hero_proc_sdk for remote job execution and TTY-backed process control
  • /hero_crates_best_practices_check for repository structure and crate organization
  • /hero_ui_dashboard for dashboard principles

The app provides a UI for authoring, previewing, generating, monitoring, and re-running automated content creation workflows.

there are 2 components for UI

  • ..._web = the enduser app which has nicer layout, check ../hero_whiteboard for style
  • ..._ui = is the dashboard

2. Goals

Primary goals

  • Make slide creation file-based, simple, and editable.
  • Make website generation template-based, automated, and observable.
  • Support job-based automation through Hero process infrastructure.
  • Ensure repeatability through hashing, deterministic inputs, and structured repo layout.
  • Make generation workflows visible and restartable from the UI.

Non-goals

  • This spec does not define the full internals of LLM prompting.
  • This spec does not define deployment of generated websites beyond generation and preview.

3. System overview

The app has two main domains:

A. Slides domain

A slide deck is stored as a folder with:

  • one file per slide
  • a shared style.md
  • generated image assets next to slide files
  • description for LLM model how the slides need to look like

The user edits slide source files in the UI using an editor with preview. The system hashes slide content and triggers automatic image regeneration when slide files change.

Image generation uses:

  • OpenRouter
  • model: Nano Banana 2 / Gemini 3.1 Flash Image Preview
  • shared style context from style.md

B. Websites domain

A website project starts from a standard internal template from Forge. Website generation is done through Cloud automation using a Cloud agent and multiple quality levels.

Generation runs as managed jobs through Hero process infrastructure, with PTY/TTY support for interactive or streamable execution, status inspection, restart, and logging.

4. Core principles

  • File-first: source of truth lives in files and folders.
  • Regeneration by hash: changed inputs cause regeneration; unchanged inputs do not.
  • Composable automation: local direct generation where simple, Cloud jobs where complex.
  • Observable jobs: every workflow exposes logs, status, timestamps, and restart capability.
  • Consistent output style: shared deck/website instructions are always injected.
  • Rust-native architecture: backend and service logic follow internal crate standards.

5. Functional specification

5.1 Main application structure

The application shall provide at least these main tabs:

  1. Slides
  2. Websites
  3. Jobs
  4. Logs
  5. Settings

Optional later tabs:

  • Templates
  • Assets
  • History
  • Prompts / Skills

5.2 Slides tab

5.2.1 Purpose

The Slides tab allows users to create and manage slide decks as folders containing one file per slide.

5.2.2 Folder-based deck model

Each deck is represented by a folder.

Recommended structure:

  slide_001.md
  slide_002.md
  slide_003.md
  slide_001.png
  slide_002.png
  slide_003.png
  assets/
  output/

Requirements

  • The system shall support selecting or creating a deck folder.
  • The system shall treat each slide source file as one slide.
  • The system shall keep generated PNG output adjacent to the source slide or in a deterministic output folder.
  • The system shall allow deck-level metadata via deck.json or equivalent.

  • The user must be able to preview slide styling immediately.
  • The slide format must support image prompt generation.

5.2.4 style.md

style.md is a required deck-level file.

Purpose:

  • define shared visual style
  • ensure consistency across all slide image generations
  • provide reusable art direction and tone

Requirements

  • style.md shall always be included when generating slide images.
  • If style.md changes, all slide generation hashes depending on it become invalid.

16. Acceptance criteria

The system is acceptable when:

  1. A user can create a slide deck with one file per slide.
  2. A user can edit style.md and slide files with live preview.
  3. The system detects file changes and marks affected outputs stale.
  4. The system can generate PNG images for slides using OpenRouter.
  5. A user can create a website project from a standard template.
  6. Website generation runs through Cloud jobs with visible status and logs.
  7. Jobs can be restarted from the UI.
  8. Logging, process execution, and crate structure align with internal Hero practices.

17. Short design summary

This app is a file-first Rust automation studio with two production tracks:

  • Slides: editable per-slide files + shared style context + hash-based image regeneration
  • Websites: template-based Agent generation with managed jobs, quality levels, and visible orchestration

It should feel like a practical internal production tool: easy to edit, easy to observe, easy to rerun, and aligned with Hero process, logging, and crate standards.

IMPORTANT CHANGES TO ABOVE

  • use TOML as filesystem format
  • try to avoid doubles between filesystem info & DB, let server integrate filesystem backend info in the object when needed when using openrpc api
  • the skills mentioned have priority on spec above

Data model # 7.1 Slide deck ```text SlideDeck { id, name, root_path, style_file, metadata_file, created_at, updated_at } ``` # 7.2 Slide ```text Slide { id, deck_id, file_path, order_index, title, current_hash, last_generated_hash, status, output_png_path, updated_at } ``` # 7.3 Website project ```text WebsiteProject { id, name, root_path, template_ref, brief_path, style_path, default_quality, created_at, updated_at } ``` # 7.4 Job ```text Job { id, kind, target_type, target_id, state, quality_level, created_at, started_at, finished_at, retry_count, remote_ref, tty_enabled, summary } ``` --- ## 8. UX requirements # 8.1 General UX * Fast loading of projects and decks * Clear stale/fresh/generating states * Minimal clicks to generate or regenerate * Strong visibility into what changed and why # 8.2 Slides UX * File list on left * source editor in center * preview/image pane on right * generation status badges per slide * one-click generate/retry # 8.3 Websites UX * project selector * brief/style/template controls * quality selector * job runner panel * output preview # 8.4 Jobs UX * table/list view * filter by status/type/project * live output stream * restart button * open related logs --- ## 9. Error handling requirements The system shall provide explicit error categories: * file system error * template fetch error * OpenRouter API error * Cloud agent execution error * timeout * invalid project structure * hash metadata mismatch * preview render failure ### Requirements * Every failed job shall have a summary and details. * User-facing errors shall be readable. * Debug details shall be preserved for developers. * Partial outputs shall be marked clearly and never treated as successful. --- ## 10. Security and operational requirements * Secrets must not be written to normal logs. * API keys must be loaded through approved secret handling. * Remote job execution must use explicit authenticated configuration. * Generated artifacts should be written only inside approved project roots. * Unsafe path traversal must be prevented. --- ## 11. Observability requirements The system shall make it easy to answer: * what changed? * what regenerated? * why did this regenerate? * which input hash produced this artifact? * which model/version produced this output? * which job failed and where? --- ## 12. MVP scope ### MVP Slides * folder-based decks * one file per slide * editable `style.md` * editor + preview * OpenRouter image generation * per-slide hashing * stale detection * manual and automatic regeneration * PNG output next to slide ### MVP Websites * create project from template * edit brief/style * launch Cloud generation job * choose quality level * monitor logs/status * restart job * preview generated site output ### MVP Platform * structured logging * job history * file watching * basic settings --- ## 13. Future scope * export to PPTX/PDF * version diff for slide prompts and images * compare website generation runs * human approval workflow * asset library * collaborative editing * prompt inspector and debugging tools * automatic validation of generated websites * publish/deploy pipeline integration --- ## 14. Open implementation questions 1. What exact slide source format should be canonical: Markdown, HTML, or hybrid? 2. Should generated PNG live adjacent to source or inside `/output`? 3. Should slide generation run inline or always through a managed job wrapper? 4. How should template version pinning work for websites? 5. What are the exact quality-level semantics for Cloud generation? 6. Which preview renderer is canonical for slides? 7. How much generation metadata should be persisted verbatim? --- ## 15. Recommended implementation order ### Phase 1 * repo/crate skeleton * filesystem models * deck/project scanning * basic UI tabs ### Phase 2 * slide editor + preview * `style.md` integration * hash + stale logic * OpenRouter PNG generation ### Phase 3 * website project creation from template * Cloud job orchestration * jobs UI and logs UI ### Phase 4 * retries/restart/history * deeper metadata persistence * improved preview and comparison tools --- ## 16. Acceptance criteria The system is acceptable when: 1. A user can create a slide deck with one file per slide. 2. A user can edit `style.md` and slide files with live preview. 3. The system detects file changes and marks affected outputs stale. 4. The system can generate PNG images for slides using OpenRouter. 5. A user can create a website project from a standard template. 6. Website generation runs through Cloud jobs with visible status and logs. 7. Jobs can be restarted from the UI. 8. Logging, process execution, and crate structure align with internal Hero practices. --- ## 17. Short design summary This app is a **file-first Rust automation studio** with two production tracks: * **Slides**: editable per-slide files + shared style context + hash-based image regeneration * **Websites**: template-based Agent generation with managed jobs, quality levels, and visible orchestration It should feel like a practical internal production tool: easy to edit, easy to observe, easy to rerun, and aligned with Hero process, logging, and crate standards. IMPORTANT CHANGES TO ABOVE - use TOML as filesystem format - try to avoid doubles between filesystem info & DB, let server integrate filesystem backend info in the object when needed when using openrpc api - the skills mentioned have priority on spec above

Implementation Spec for Issue #1 -- Hero Studio Initial Scaffold

Objective

Set up the complete Cargo workspace scaffold for Hero Studio (hero_webbuilder), a Rust-first automation workspace for creating slides and websites. This creates all crate skeletons, core data models, an initial OpenRPC spec, server/SDK/UI/web binaries, and build infrastructure — following the established hero ecosystem patterns demonstrated by hero_whiteboard.

Requirements

  • Create a Cargo workspace with 8 crates: hero_studio_core, hero_studio_server, hero_studio_sdk, hero_studio_ui, hero_studio_web, hero_studio_slides, hero_studio_websites, hero_studio_jobs
  • All crates live under crates/
  • Follow hero_whiteboard conventions: Unix socket only, hero_proc_sdk integration, OpenRPC API, Axum+Askama+Bootstrap UI, clap CLI with serve/start/stop/status/logs subcommands
  • Data models use TOML as filesystem format (not JSON)
  • SQLite database for metadata (rusqlite + rusqlite_migration)
  • Database at ~/hero/var/data/hero_studio/studio.db
  • Sockets at ~/hero/var/sockets/hero_studio_*.sock

Crate Responsibilities

Crate Type Responsibility
hero_studio_core library Domain models, shared types, TOML serialization
hero_studio_server binary Business logic, SQLite, OpenRPC API, Unix socket, job orchestration
hero_studio_sdk library JSON-RPC client over Unix socket
hero_studio_ui binary Admin dashboard (Axum + Askama + Bootstrap 5.3.3)
hero_studio_web binary End-user website/slide viewer
hero_studio_slides library Slide domain: file hashing, stale detection, deck management
hero_studio_websites library Website domain: template management, brief/style handling
hero_studio_jobs library Job abstraction, orchestration, OpenRouter integration

Implementation Plan (9 Steps)

Step 1: Root workspace and build infrastructure

  • Workspace Cargo.toml, Makefile, buildenv.sh, CLAUDE.md, scripts

Step 2: hero_studio_core — domain models

  • SlideDeck, Slide, WebsiteProject, Job structs
  • JobKind, JobState, SlideStatus, QualityLevel, TargetType enums

Step 3: hero_studio_slides — slide domain logic (parallel with 4, 5)

  • hash_slide_content, detect_stale_slides, parse_deck_toml, scan_deck_directory

Step 4: hero_studio_websites — website domain logic (parallel with 3, 5)

  • parse_project_toml, list_templates, validate_project_structure

Step 5: hero_studio_jobs — job abstraction (parallel with 3, 4)

  • JobManager, create_job, transition_state

Step 6: hero_studio_server — server skeleton

  • Database, migrations, RPC router, handler stubs, OpenRPC spec, hero_proc_sdk

Step 7: hero_studio_sdk — client library

  • HeroStudioClient with typed methods for all OpenRPC methods

Step 8: hero_studio_ui — admin dashboard (parallel with 9)

  • Axum + Askama + Bootstrap, RPC proxy, sidebar nav

Step 9: hero_studio_web — end-user web (parallel with 8)

  • End-user viewer with clean templates

Acceptance Criteria

  • cargo check --workspace passes
  • cargo build --workspace compiles all 8 crates
  • cargo test --workspace passes
  • cargo clippy --workspace --all-targets -- -D warnings passes
  • Workspace has 8 crate members under crates/
  • Server has valid openrpc.json with all CRUD methods
  • SQLite migration creates tables for all entities
  • make build works end-to-end

Notes

  • Pattern fidelity to hero_whiteboard is critical
  • TOML for filesystem, SQLite for DB, JSON-RPC for API
  • No doubles between filesystem and DB — server merges on demand
  • hero_studio_openrouter from the issue maps to a module within hero_studio_jobs (not a separate crate at scaffold stage)

Test Results

  • cargo check --workspace: PASS
  • cargo test --workspace: PASS (all tests pass, 0 failures)
  • cargo clippy --workspace: PASS (minor warnings only - dead code, too-many-args on stubs)
  • cargo build --workspace: PASS

Minor Warnings (non-blocking)

  • hero_studio_slides: map_or can be simplified
  • hero_studio_web: unused base_path field (will be used when routes are implemented)
  • hero_studio_server: some handler stubs have too many arguments (will be refactored when implementing real logic)

All 8 crates compile and link successfully.
