# GEMINI.md
|
|
|
|
This file provides context and guidance for Gemini (and other AI agents) when working with the Grimoire repository.
|
|
|
|
## Project Overview
|
|
|
|
Grimoire is a Nostr protocol explorer and developer tool. It features a tiling window manager interface where each window is a Nostr "app" (profile viewer, event feed, NIP documentation, etc.). Commands are launched Unix-style via a `Cmd+K` palette.
|
|
|
|
**Stack:** React 19 + TypeScript + Vite + TailwindCSS + Jotai + Dexie + Applesauce
|
|
|
|
## Core Architecture
|
|
|
|
### 1. Dual State System
|
|
|
|
* **UI State** (`src/core/state.ts` + `src/core/logic.ts`):
|
|
* Managed by **Jotai** atoms, persisted to `localStorage`.
|
|
* **Mutations:** strict adherence to pure functions in `src/core/logic.ts` (`(state, payload) => newState`).
|
|
* **Scope:** Workspaces, windows, layout tree, active account.
|
|
|
|
* **Nostr State** (`src/services/event-store.ts`):
|
|
* **Singleton `EventStore`** from `applesauce-core`.
|
|
* Single source of truth for all Nostr events.
|
|
* Reactive: Components subscribe via hooks (`useProfile`, `useTimeline`, `useNostrEvent`).
|
|
* **CRITICAL:** Do NOT create new `EventStore` instances. Use the singleton in `src/services/`.
|
|
|
|
* **Relay State** (`src/services/relay-liveness.ts`):
|
|
* Singleton `RelayLiveness` tracks relay health.
|
|
* Persisted to Dexie.
|
|
|
|
### 2. Window System
|
|
|
|
* **Layout:** Recursive binary split layout via `react-mosaic-component`.
|
|
* **Structure:**
|
|
* **Leaf:** Window ID (UUID).
|
|
* **Branch:** Split space.
|
|
* **Constraint:** **Never manipulate the layout tree directly.** Use `updateLayout()` callbacks or `logic.ts` helpers.
|
|
* **Window Props:** `id`, `appId` (type identifier), `title`, `props`.
|
|
|
|
### 3. Command System
|
|
|
|
* **Definition:** `src/types/man.ts` defines commands as Unix man pages.
|
|
* **Flow:** User types command -> `argParser` resolves props -> Helper opens specific `appId` viewer.
|
|
* **Global Flags:** Defined in `src/lib/global-flags.ts` (e.g., `--title` overrides window title).
|
|
|
|
### 4. Reactive Nostr Pattern
|
|
|
|
* **Flow:** Relays -> EventStore -> Observables -> Component Hooks.
|
|
* **Helpers:** Use `applesauce-react` hooks or custom hooks in `src/hooks/`.
|
|
* **Replaceable Events:** Handled automatically by EventStore (kinds 0, 3, 10000+, 30000+).
|
|
|
|
## Key Conventions
|
|
|
|
* **Path Alias:** `@/` maps to `./src/`.
|
|
* **Styling:** TailwindCSS + HSL variables for theming (defined in `index.css`).
|
|
* **Organization:** Domain-based (`nostr/`, `ui/`, `services/`, `hooks/`, `lib/`).
|
|
* **Types:** Prefer `applesauce-core` types; extend in `src/types/`.
|
|
|
|
## Important Patterns
|
|
|
|
### Adding New Commands
|
|
1. Add entry to `manPages` in `src/types/man.ts`.
|
|
2. Create argument parser in `src/lib/*-parser.ts`.
|
|
3. Create viewer component for the `appId`.
|
|
4. Register viewer in `WindowTitle.tsx` (or equivalent registry).
|
|
|
|
### Event Rendering
|
|
* **Pattern:** Registry-based rendering.
|
|
* **Files:** `src/components/nostr/kinds/index.tsx`.
|
|
* **Components:** `KindRenderer` (feed) and `DetailKindRenderer` (detail/full view).
|
|
* **Naming:** Use descriptive names (`LiveActivityRenderer`) not numbers (`Kind30311Renderer`).
|
|
* **Safety:** All renderers are wrapped in `EventErrorBoundary`.
|
|
|
|
### Testing
|
|
* **Framework:** Vitest.
|
|
* **Commands:**
|
|
* `npm test`: Watch mode.
|
|
* `npm run test:run`: CI mode (single run).
|
|
* **Focus:** Test pure functions in `logic.ts`, parsers in `lib/*-parser.ts`, and utilities.

## Critical Rules for Agents
|
|
|
|
> [!IMPORTANT]
|
|
> **Do NOT create new instances of singletons.**
|
|
> * `EventStore`, `RelayPool`, `RelayLiveness` are singletons in `src/services/`.
|
|
|
|
> [!IMPORTANT]
|
|
> **Respect the Layout Tree.**
|
|
> * Do not manually traverse or modify the Mosaic layout object. Use specific update callbacks.
|
|
|
|
> [!NOTE]
|
|
> **Use the Knowledge Base.**
|
|
> * Refer to `CLAUDE.md` for the original documentation source.
|
|
> * Check `.claude/skills` for library-specific documentation (Applesauce, Nostr tools).
