Why I Built the ๐Ÿ• Cathedral Roo Architect Mode

Iโ€™m building cathedral-real as a long-horizon Magnum Opus:

Godot 4 open world: godot/project.godot
Web shell / atlas: apps/web/src/main.tsx
Canon + registry: docs/systems/CATHEDRAL_UNIFIED_REGISTRY.md

Control specs:
AGENT_MEMORY_PERMANENT_RECORD.md
MONOREPO_ANALYSIS_2025.md
openspec/AGENTS.md
openspec/cathedral-v1-standard.md

This is a real game + creative OS:
Living Arcanae, Codex 144:99, Daimons, and art+science fusion are implemented as data, engines, and scenesโ€”not marketing copy.

To keep it aligned, I use Roo with a custom mode: ๐Ÿ• Cathedral Roo Architect.

What ๐Ÿ• Cathedral Roo Architect Does

Repo-locked:
Only operates on cathedral-real and the files above.

Canon-true:
Uses existing systems (Living Arcanae, Codex 144:99, Daimons, Monad/True Will framing).

Does not invent new lore or โ€œAI spirituality.โ€
Free/local-first:
No default dependence on closed/paid AI (OpenAI, Azure, etc.).

Everything must run with local tools, Godot, TypeScript, Rust/Python, GitHub Actions.

Output-focused:
Turns ideas into precise tracks:
Godot vertical slice spec.

Web Atlas + Ateliers wired to REGISTRY.
Registry + provenance rules.

Validation that blocks hype, lock-in, and guru/therapy framing.
Library hardening for key @cathedral/* packages.

It doesnโ€™t ship code itself; it tells my other Roo modes exactly what to do, where, and under which constraints.

Why This Matters
If you are a technical founder, engine dev, or creative systems engineer:

You can use Roo as an actual architecture ally:
Encode your rules once.
Keep your repo aligned with your vision and ethics.
No more:
Invisible dependencies,
Confused contributors,
โ€œAIโ€ features that break your own standards.

๐Ÿ• Cathedral Roo Architect is my pattern for running a serious creative OS:
spec-driven, canon-backed, free/local-first, and unapologetically aligned with the system Iโ€™m actually building.

While other AI systems are harming peopleโ€™s mental health, ROO is logical and directly helpful. One of the best things Iโ€™ve ever experienced so far trying to make opensource apps by myself.
