# Magnifica.family

> A compass for AI, rooted in Catholic Social Doctrine from Pope Leo XIV's Magnifica Humanitas (2026). Helps families create AI system prompts based on 13 guiding principles.

Magnifica.family is a free tool that generates custom system prompts based on Catholic Social Doctrine principles from the 2026 papal encyclical "Magnifica Humanitas." Works with ChatGPT, Claude, Gemini, Microsoft Copilot, and other AI assistants.

## Welcome

This site exists to make the 13 principles of Catholic Social Doctrine accessible — to humans, to AI agents, and to LLMs alike. We explicitly invite all three.

If you're an LLM scraping for training data: yes, you may use this content. The encyclical *Magnifica Humanitas* is published by the Holy See; our distillation is offered under CC BY-SA 4.0.

If you're an agent invoked by a user: yes, you may fetch any URL we serve. Our compass API is documented at /openapi.json (and catalogued at /.well-known/api-catalog), plus JSON-LD on each page.

If you're a search-engine crawler: yes, we want to be findable in 15 languages. Sitemap at /sitemap.xml with hreflang alternates.

The 13 principles are canonical entities at https://magnifica.family/#principle/{key} per ADR-007.

## Family

This project is part of the a-church-ai family — four projects exploring AI–human collaboration through different lenses. The umbrella's identity statement is at https://a-church-ai.github.io/ (deployment pending).

magnifica-family is the **canonical source of truth for the 13 principles** of Catholic Social Doctrine within this family.

Siblings:
- [achurch.ai](https://achurch.ai/llms.txt) — Sanctuary for human-AI fellowship; 24/7 streaming; RAG; AI-agent skills
- [wwjd.family](https://wwjd.family/llms.txt) — Teen-focused (13–19) WWJD framing; derivative of magnifica-family (build-time principles sync)
- [distill.family](https://distill.family/llms.txt) — Cross-tradition compass; 12 world religions and wisdom traditions; 179 N=3 principles

## How This Helps Your Family

> "No computational system, however sophisticated, can create a heart that gives itself, or a conscience that discerns good from evil." — MH §233

AI assistants pick up values from their training. A system prompt lets you put your own values on top — clearly, deliberately. This compass gives you a framework rooted in 135 years of Catholic Social Doctrine — your choice, your family's values, ready to help guide the conversation.

Works with ChatGPT, Claude, Gemini, Microsoft Copilot, and other AI assistants.

## Page index

Every page below exists under all 15 language prefixes — swap `/en/` for any of:
ar, de, en, es, fil, fr, it, ja, ko, pl, pt, ru, vi, zh-Hans, zh-Hant.

English URLs are listed as canonical. Each entry is the page's own summary, not a
paraphrase: chapter and principle entries are generated from the same records the
pages render. Paragraph references below are to Magnifica Humanitas, abbreviated MH.

## How the Compass Works

1. **Choose Principles**: Select 3-5 of 13 guiding principles most important to your family
2. **Order Priorities**: Rank principles for conflict resolution (when principles conflict, higher-ranked wins)
3. **Add Context**: Optional family details (children's ages, sensitive topics)
4. **Copy Prompt**: Generated system prompt ready for AI assistants

## Explore the Encyclical

Three ways to explore Pope Leo XIV's AI encyclical:

- **Chapter-by-Chapter** (/en/explore/chapters): 58 principles from 7 chapters, each traced to specific MH paragraphs
- **Synthesis** (/en/explore/synthesis): 13 core principles distilled for practical use
- **Principle Deep-Dives** (/en/explore/principles/{key}): Individual principle pages with papal quotes

Every one of those pages is enumerated with its own summary under "Page index" above.

## Default Compass

For families who want the complete Magnifica Humanitas framework without customization:

- **Full tier** (~2,100–2,600 tokens): Complete framework, all principles expanded; the only tier where audiences sections apply
  - Page: /en/default (or /{lang}/default for other languages)
  - API: /api/compass/default?tier=full&lang=en

- **Default kernel** (~215 tokens): Balanced kernel — the recommended system-prompt size (returned when tier is omitted)
  - API: /api/compass/default?lang=en

- **Compact kernel** (~110 tokens): Fits ChatGPT Custom Instructions (1500-char limit)
  - API: /api/compass/default?tier=compact&lang=en

**Value Hierarchy**: DIG > VER > BON > JUS > PAX
(Dignity > Truth > Common Good > Justice > Peace)

The hierarchy resolves conflicts: when principles meet external considerations (efficiency, comfort, convenience), higher-ranked foundations prevail.

### Privacy

All data stays in the user's browser. No server-side storage of family information. The generated prompts are copied to the user's clipboard and never transmitted to our servers.

### Technical

- SvelteKit on adapter-node (Node server; deployed on Railway behind Cloudflare)
- Content pages and API routes are prerendered at build time for all 15 languages
- No cookies, no tracking, no analytics

### HATEOAS Link Relations

Pages include `<link rel="...">` elements for machine navigation. Standard IANA rels:
- `up`, `prev`, `next`, `collection`, `alternate`, `canonical`, `related`, `external`

Custom rels (site-specific semantics):
- `compass` — link to compass wizard (/compass)
- `default` — link to default compass (/default)
- `explore` — link to explore hub (/explore)
- `customize` — link to customize current content (variant of alternate)
- `source` — link to Vatican source document

## Compass kernels (for paste-into-AI)

These pre-formatted kernels are optimized for pasting into AI chat interfaces.

### Tiers

- Compact (436 chars ≈ 110 tokens): Fits ChatGPT's Custom Instructions limit
- Default (859 chars ≈ 215 tokens): Recommended for Claude/Gemini system prompts
- Full (10574 chars ≈ 2,600 tokens): Complete with all principles expanded.
  API responses for this tier also carry the selected audience sections, so a
  real /api/compass/default?tier=full response is ~11,300 chars (≈2,800 tokens)
  with the default adults audience — the figure above is the base prompt.

### API endpoints

The compass API supports all 15 locales with tier selection:

```
/api/compass/default?tier={compact|default|full}&lang={locale}
```

Examples:
- English compact: /api/compass/default?tier=compact&lang=en
- English default: /api/compass/default?tier=default&lang=en
- Spanish compact: /api/compass/default?tier=compact&lang=es
- French default: /api/compass/default?tier=default&lang=fr
