+
+
+
+## Key Design Decisions
+
+- **Anonymous Sessions**: Uses localStorage `sessionId` (UUID) until auth is added
+- **Chat Scope**: Per-page using slug as context identifier (e.g., "write-page", "about", "my-post-slug")
+- **Page Context**: Optional button to load current page's markdown into chat context
+- **Mode Toggle**: Write page switches between textarea and chat interface
+- **Configuration**: Separate siteConfig toggles for Write page and RightSidebar
+
+---
+
+## 1. Database Schema Updates
+
+Update [`convex/schema.ts`](convex/schema.ts) to add the `aiChats` table:
+
+```typescript
+aiChats: defineTable({
+  sessionId: v.string(),
+  contextId: v.string(), // slug or "write-page"
+  messages: v.array(
+    v.object({
+      role: v.union(v.literal("user"), v.literal("assistant")),
+      content: v.string(),
+      timestamp: v.number(),
+    }),
+  ),
+  pageContext: v.optional(v.string()), // loaded page content
+  lastMessageAt: v.optional(v.number()),
+})
+  .index("by_session_and_context", ["sessionId", "contextId"])
+  .index("by_session", ["sessionId"])
+```
+
+---
+
+## 2. Convex Backend
+
+### Create [`convex/aiChats.ts`](convex/aiChats.ts)
+
+Queries and mutations for chat management:
+
+- `getAIChatByContext` - Fetch chat for sessionId + contextId
+- `getOrCreateAIChat` - Create chat if none exists
+- `addUserMessage` - Add user message
+- `addAssistantMessage` - Internal mutation for AI response
+- `clearChat` - Clear messages
+- `setPageContext` - Store loaded page content
+
+### Create [`convex/aiChatActions.ts`](convex/aiChatActions.ts)
+
+Node.js action for Claude API:
+
+- `generateResponse` - Calls Claude API with conversation history
+- Uses `ANTHROPIC_API_KEY` environment variable
+- Loads system prompt from `CLAUDE_SYSTEM_PROMPT` or split `CLAUDE_PROMPT_*` variables
+- Model: `claude-sonnet-4-20250514` with 2048 max tokens
+- Includes last 20 messages as context
+
+---
+
+## 3. Frontend Components
+
+### Create [`src/components/AIChatView.tsx`](src/components/AIChatView.tsx)
+
+Main chat component with:
+
+- Message list with markdown rendering (react-markdown)
+- Auto-expanding textarea input
+- Send button and keyboard shortcuts (Enter to send, Shift+Enter newline)
+- Loading state with stop generation button
+- Clear chat command ("clear")
+- Copy message button on AI responses
+- "Load Page Content" button (when page content available)
+- Theme-aware styling matching existing UI
+
+### Update [`src/components/RightSidebar.tsx`](src/components/RightSidebar.tsx)
+
+Transform from empty placeholder to conditional chat container:
+
+- Accept `aiChatEnabled`, `pageContent`, and `slug` props
+- Render `AIChatView` when enabled
+- Pass page context for "Load Content" feature
+
+---
+
+## 4. Page Updates
+
+### Update [`src/pages/Write.tsx`](src/pages/Write.tsx)
+
+Add AI chat mode toggle:
+
+- New state: `isAIChatMode` (boolean)
+- Add "AI Chat" button in Actions section (using `ChatCircle` from Phosphor Icons)
+- When active: replace `<textarea>` with `<AIChatView contextId="write-page" />`
+- Show "Back to Editor" button to switch back
+- Respect `siteConfig.aiChat.enabledOnWritePage` setting
+
+### Update [`src/pages/Post.tsx`](src/pages/Post.tsx)
+
+Pass content to RightSidebar:
+
+- Check `siteConfig.aiChat.enabledOnContent` AND frontmatter `aiChat: true`
+- Pass `pageContent={content}` and `slug` to RightSidebar
+- Add new frontmatter field `aiChat` to field definitions
+
+---
+
+## 5. Configuration
+
+### Update [`src/config/siteConfig.ts`](src/config/siteConfig.ts)
+
+Add AI chat configuration interface and defaults:
+
+```typescript
+export interface AIChatConfig {
+  enabledOnWritePage: boolean;  // Show AI chat on /write
+  enabledOnContent: boolean;    // Allow AI chat on posts/pages via frontmatter
+}
+
+// In SiteConfig interface:
+aiChat: AIChatConfig;
+
+// Default values:
+aiChat: {
+  enabledOnWritePage: true,
+  enabledOnContent: true,
+},
+```
+
+
+
+### Update Frontmatter Fields
+
+Add `aiChat` field to sync scripts and field definitions:
+
+- [`scripts/sync-posts.ts`](scripts/sync-posts.ts) - Add to PostFrontmatter and PageFrontmatter
+- [`src/pages/Write.tsx`](src/pages/Write.tsx) - Add to POST_FIELDS and PAGE_FIELDS
+
+---
+
+## 6. Styling
+
+### Update [`src/styles/global.css`](src/styles/global.css)
+
+Add AI chat styles (approximately 300-400 lines):
+
+- `.ai-chat-view` - Main container
+- `.ai-chat-messages` - Scrollable message list
+- `.ai-chat-message`, `.ai-chat-message-user`, `.ai-chat-message-assistant`
+- `.ai-chat-input-container`, `.ai-chat-input`, `.ai-chat-send-button`
+- `.ai-chat-loading`, `.ai-chat-stop-button`
+- `.ai-chat-copy-button`, `.ai-chat-clear-button`
+- `.ai-chat-load-context-button`
+- Theme variants for dark, light, tan, cloud
+- Mobile responsive styles
+
+---
+
+## 7. Dependencies
+
+### Update [`package.json`](package.json)
+
+Add required packages:
+
+```json
+"@anthropic-ai/sdk": "^0.71.2"
+```
+
+Note: `react-markdown` and `remark-gfm` already exist in the project.---
+
+## 8. Environment Variables
+
+Add to Convex deployment:
+
+- `ANTHROPIC_API_KEY` (required) - Claude API key
+- `CLAUDE_SYSTEM_PROMPT` (optional) - Custom system prompt for writing assistant

+```
+
+
+
+## Implementation Steps
+
+### 1. Update `src/config/siteConfig.ts`
+
+Add homepage configuration interface and default:
+
+```typescript
+// Add to SiteConfig interface
+export interface HomepageConfig {
+  type: "default" | "page" | "post";
+  slug?: string; // Required if type is "page" or "post"
+  originalHomeRoute?: string; // Route to access original homepage (default: "/home")
+}
+
+export interface SiteConfig {
+  // ... existing fields ...
+  homepage: HomepageConfig;
+}
+
+// Add to siteConfig object
+export const siteConfig: SiteConfig = {
+  // ... existing config ...
+  homepage: {
+    type: "default", // Options: "default", "page", "post"
+    slug: undefined, // e.g., "about" or "welcome-post"
+    originalHomeRoute: "/home", // Route to access original homepage
+  },
+};
+```
+
+
+
+### 2. Update `src/App.tsx`
+
+Modify routing to conditionally render homepage:
+
+```typescript
+function App() {
+  usePageTracking();
+  const location = useLocation();
+
+  if (location.pathname === "/write") {
+    return <Write />;
+  }
+
+  // Determine if we should use a custom homepage
+  const useCustomHomepage = 
+    siteConfig.homepage.type !== "default" && 
+    siteConfig.homepage.slug;
+
+  return (
+    <SidebarProvider>
+      <Layout>
+        <Routes>
+          {/* Homepage route - either default Home or custom page/post */}
+          <Route 
+            path="/" 
+            element={
+              useCustomHomepage ? (
+                <Post 
+                  slug={siteConfig.homepage.slug!} 
+                  isHomepage={true}
+                  homepageType={siteConfig.homepage.type}
+                />
+              ) : (
+                <Home />
+              )
+            } 
+          />
+          
+          {/* Original homepage route (when custom homepage is set) */}
+          {useCustomHomepage && (
+            <Route 
+              path={siteConfig.homepage.originalHomeRoute || "/home"} 
+              element={<Home />} 
+            />
+          )}
+          
+          {/* ... rest of routes ... */}
+        </Routes>
+      </Layout>
+    </SidebarProvider>
+  );
+}
+```
+
+
+
+### 3. Update `src/pages/Post.tsx`
+
+Add props to support homepage mode and hide back button:
+
+```typescript
+interface PostProps {
+  slug?: string; // Optional slug prop when used as homepage
+  isHomepage?: boolean; // Flag to indicate this is the homepage
+  homepageType?: "page" | "post"; // Type of homepage content
+}
+
+export default function Post({ 
+  slug: propSlug, 
+  isHomepage = false,
+  homepageType 
+}: PostProps = {}) {
+  const { slug: routeSlug } = useParams<{ slug: string }>();
+  const slug = propSlug || routeSlug;
+  
+  // ... existing queries ...
+  
+  // Conditionally hide back button when used as homepage
+  // In the render section:
+  {!isHomepage && (
+    <button onClick={() => navigate("/")} className="back-button">
+      <ArrowLeft size={16} />
+      <span>Back</span>
+    </button>
+  )}
+  
+  // ... rest of component unchanged ...
+}
+```
+
+
+
+### 4. Update `scripts/configure-fork.ts`
+
+Add homepage configuration support:
+
+```typescript
+interface ForkConfig {
+  // ... existing fields ...
+  homepage?: {
+    type: "default" | "page" | "post";
+    slug?: string;
+    originalHomeRoute?: string;
+  };
+}
+
+// Add update function
+function updateSiteConfig(config: ForkConfig): void {
+  // ... existing updates ...
+  
+  if (config.homepage) {
+    const homepageConfig = JSON.stringify(config.homepage, null, 2)
+      .replace(/"/g, '"')
+      .replace(/\n/g, '\n    ');
+    
+    updateFile(
+      "src/config/siteConfig.ts",
+      [
+        {
+          search: /homepage:\s*\{[^}]*\},/s,
+          replace: `homepage: ${homepageConfig},`,
+        },
+      ]
+    );
+  }
+}
+```
+
+
+
+### 5. Update `FORK_CONFIG.md`
+
+Add homepage configuration section:
+
+````markdown
+## Homepage Configuration
+
+You can set any page or blog post to serve as your homepage.
+
+### In fork-config.json
+
+```json
+{
+  "homepage": {
+    "type": "page",
+    "slug": "about",
+    "originalHomeRoute": "/home"
+  }
+}
+````
+
+Options:
+
+- `type`: `"default"` (standard homepage), `"page"` (use a static page), or `"post"` (use a blog post)
+- `slug`: The slug of the page or post to use (required if type is "page" or "post")
+- `originalHomeRoute`: Route to access the original homepage (default: "/home")
+
+### Manual Configuration
+
+In `src/config/siteConfig.ts`:
+
+```typescript
+homepage: {
+  type: "page", // or "post" or "default"
+  slug: "about", // slug of page/post to use
+  originalHomeRoute: "/home", // route to original homepage
+},
+```
+
+
+
+### Notes
+
+- Custom homepage uses the page/post's full content and features (sidebar, copy dropdown, etc.)
+- Featured section is NOT shown on custom homepage
+- SEO metadata comes from the page/post's frontmatter
+- Original homepage remains accessible at `/home` when custom homepage is set
+````javascript
+
+### 6. Update `fork-config.json.example`
+
+Add homepage configuration example:
+
+```json
+{
+  "homepage": {
+    "type": "default",
+    "slug": null,
+    "originalHomeRoute": "/home"
+  }
+}
+````
+
+
+
+
+## Files to Modify
+
+1. `src/config/siteConfig.ts` - Add HomepageConfig interface and default config
+2. `src/App.tsx` - Conditional homepage routing
+3. `src/pages/Post.tsx` - Add props for homepage mode, hide back button
+4. `scripts/configure-fork.ts` - Add homepage config parsing and file updates
+5. `FORK_CONFIG.md` - Document homepage configuration
+6. `fork-config.json.example` - Add homepage config example

+## AI Agent chat
+
+The site includes an AI writing assistant (Agent) powered by Anthropic Claude API. Agent can be enabled in two places:
+
+**1. Write page (`/write`)**
+
+Enable Agent mode on the Write page via `siteConfig.aiChat.enabledOnWritePage`. When enabled, a toggle button appears in the Actions section. Clicking it replaces the textarea with the Agent chat interface. The page title changes to "Agent" when in chat mode.
+
+**Configuration:**
+
+```typescript
+// src/config/siteConfig.ts
+aiChat: {
+  enabledOnWritePage: true, // Enable Agent toggle on /write page
+  enabledOnContent: true,    // Allow Agent on posts/pages via frontmatter
+},
+```
+
+**2. Right sidebar on posts/pages**
+
+Enable Agent in the right sidebar on individual posts or pages using the `aiChat` frontmatter field. Requires both `rightSidebar: true` and `siteConfig.aiChat.enabledOnContent: true`.
+
+**Frontmatter example:**
+
+```markdown
+---
+title: "My Post"
+rightSidebar: true
+aiChat: true  # Enable Agent in right sidebar
+---
+```
+
+**Environment variables:**
+
+Agent requires the following Convex environment variables:
+
+- `ANTHROPIC_API_KEY` (required): Your Anthropic API key for Claude API access
+- `CLAUDE_PROMPT_STYLE` (optional): First part of system prompt
+- `CLAUDE_PROMPT_COMMUNITY` (optional): Second part of system prompt
+- `CLAUDE_PROMPT_RULES` (optional): Third part of system prompt
+- `CLAUDE_SYSTEM_PROMPT` (optional): Single system prompt (fallback if split prompts not set)
+
+**Setting environment variables:**
+
+1. Go to [Convex Dashboard](https://dashboard.convex.dev)
+2. Select your project
+3. Navigate to Settings > Environment Variables
+4. Add `ANTHROPIC_API_KEY` with your API key value
+5. Optionally add system prompt variables (`CLAUDE_PROMPT_STYLE`, etc.)
+6. Deploy changes
+
+**How it works:**
+
+- Agent uses anonymous session IDs stored in localStorage for chat history
+- Each post/page has its own chat context (identified by slug)
+- Chat history is stored per-session, per-context in Convex (aiChats table)
+- Page content can be provided as context for AI responses
+- Chat history limited to last 20 messages for efficiency
+- If API key is not set, Agent displays "API key is not set" error message
+
+**Error handling:**
+
+If `ANTHROPIC_API_KEY` is not configured in Convex environment variables, Agent displays a user-friendly error message: "API key is not set". This helps identify when the API key is missing in production deployments.

+## Getting Started
+
 Reference documentation for setting up, customizing, and deploying this markdown framework.
 
 **How publishing works:** Write posts in markdown, run `npm run sync` for development or `npm run sync:prod` for production, and they appear on your live site immediately. No rebuild or redeploy needed. Convex handles real-time data sync, so connected browsers update automatically.

 **How publishing works:** Write posts in markdown, run `npm run sync` for development or `npm run sync:prod` for production, and they appear on your live site immediately. No rebuild or redeploy needed. Convex handles real-time data sync, so connected browsers update automatically.

When enabled, CopyPageDropdown moves from the navigation bar to the right sidebar on wide screens.

+## AI Agent chat
+
+The site includes an AI writing assistant (Agent) powered by Anthropic Claude API. Agent can be enabled in two places:
+
+**1. Write page (`/write`)**
+
+Enable Agent mode on the Write page via `siteConfig.aiChat.enabledOnWritePage`. When enabled, a toggle button appears in the Actions section. Clicking it replaces the textarea with the Agent chat interface. The page title changes to "Agent" when in chat mode.
+
+**Configuration:**
+
+```typescript
+// src/config/siteConfig.ts
+aiChat: {
+  enabledOnWritePage: true, // Enable Agent toggle on /write page
+  enabledOnContent: true,    // Allow Agent on posts/pages via frontmatter
+},
+```
+
+**2. Right sidebar on posts/pages**
+
+Enable Agent in the right sidebar on individual posts or pages using the `aiChat` frontmatter field. Requires both `rightSidebar: true` and `siteConfig.aiChat.enabledOnContent: true`.
+
+**Frontmatter example:**
+
+```markdown
+---
+title: "My Post"
+rightSidebar: true
+aiChat: true  # Enable Agent in right sidebar
+---
+```
+
+**Environment variables:**
+
+Agent requires the following Convex environment variables:
+
+- `ANTHROPIC_API_KEY` (required): Your Anthropic API key for Claude API access
+- `CLAUDE_PROMPT_STYLE` (optional): First part of system prompt
+- `CLAUDE_PROMPT_COMMUNITY` (optional): Second part of system prompt
+- `CLAUDE_PROMPT_RULES` (optional): Third part of system prompt
+- `CLAUDE_SYSTEM_PROMPT` (optional): Single system prompt (fallback if split prompts not set)
+
+**Setting environment variables:**
+
+1. Go to [Convex Dashboard](https://dashboard.convex.dev)
+2. Select your project
+3. Navigate to Settings > Environment Variables
+4. Add `ANTHROPIC_API_KEY` with your API key value
+5. Optionally add system prompt variables (`CLAUDE_PROMPT_STYLE`, etc.)
+6. Deploy changes
+
+**How it works:**
+
+- Agent uses anonymous session IDs stored in localStorage for chat history
+- Each post/page has its own chat context (identified by slug)
+- Chat history is stored per-session, per-context in Convex (aiChats table)
+- Page content can be provided as context for AI responses
+- Chat history limited to last 20 messages for efficiency
+- If API key is not set, Agent displays "API key is not set" error message
+
+**Error handling:**
+
+If `ANTHROPIC_API_KEY` is not configured in Convex environment variables, Agent displays a user-friendly error message: "API key is not set". This helps identify when the API key is missing in production deployments.
