+## 2024-05-24 - Added Content Description to Retry Icon
+**Learning:** Icon-only buttons frequently lack ARIA labels/content descriptions which makes them inaccessible for screen reader users.
+**Action:** Identify `IconButton` components without associated text labels and ensure they have a proper `contentDescription`.

+# Generative UI ("Interactive UI") Specification
+
+This document details the exact technical implementation, state management, and file mappings for the Generative UI feature in Kai. This is intended as a development reference document with explicit code bindings.
+
+## Overview
+Generative UI allows the AI to render interactive compose components using JSON structures within `kai-ui` code fences instead of just text/markdown. It operates in two primary modes:
+1. **Dynamic UI:** Inline components mixed with standard Markdown inside standard chat messages.
+2. **Interactive UI Mode:** A full-screen immersive mode where the *entire* AI response is parsed as a single UI layout without visible Markdown.
+
+## File Mappings and Roles
+
+### UI / View Layer
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/ui/chat/ChatScreen.kt`
+  - **Role:** Routes UI based on mode. When `uiState.isInteractiveMode && !uiState.isRestoring` is true, it renders the full-screen `InteractiveModeScreen`. Otherwise, it falls back to standard `ChatModeScreen`.
+  - **Key Functions:** `InteractiveModeScreen(uiState: ChatUiState)` renders the immersive prompt input, navigation bar (back/exit), and displays the active tool calling/agentic loop interface.
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/ui/chat/composables/BotMessage.kt`
+  - **Role:** Integration point for parsing and rendering the actual message content.
+  - **Key Workflow:** Markdown is parsed, and blocks of type `KaiUiBlock` are intercepted. These are rendered via the `KaiUiRenderer()`.
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/ui/chat/ChatUiState.kt`
+  - **Role:** Holds the `isInteractiveMode` flag and manages UI state.
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/ui/chat/ChatActions.kt`
+  - **Role:** Exposes lambdas for controlling the Interactive UI lifecycle (`enterInteractiveMode`, `exitInteractiveMode`, `goBackInteractiveMode`, `submitUiCallback`, `resubmit`).
+
+### State Management & ViewModel
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/ui/chat/ChatViewModel.kt`
+  - **Role:** Lifecycle and execution of the Interactive UI flow.
+  - **Key Functions:**
+    - `enterInteractiveMode()` / `exitInteractiveMode()`: Toggles the `isInteractiveMode` flag via `DataRepository`.
+    - `goBackInteractiveMode()`: Uses `dataRepository.popLastExchange()` or clears history to step backwards without exiting the mode entirely.
+    - `submitUiCallback(event, data)`: Dispatches form values back to the agent as a user prompt (`Pressed: <event>` or `Responded with: ...`).
+    - `retryIfNoValidKaiUi()`: Called automatically on submission. If the LLM responds without a `kai-ui` code fence, it injects a system correction prompt (`[SYSTEM] Your previous response failed to render as interactive UI...`) and retries up to 2 times.
+
+### Prompt & System Constraints
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/data/ChatSystemPromptBuilder.kt`
+  - **Role:** Modifies the system prompt based on active modes.
+  - **Key Functions:** `appendDynamicUiSection()` and `appendInteractiveUiSection()`.
+  - **Behavior:** For `INTERACTIVE_UI`, it appends rules forcing the LLM to output ONLY a single `kai-ui` block, strictly detailing that users see *nothing* outside of it. It injects `KAI_UI_COMPONENT_CATALOG` to map JSON schemas.
+
+### Data & Persistence
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/data/DataRepository.kt` & `RemoteDataRepository.kt`
+  - **Role:** Manages conversation state and history persistence.
+  - **Key Interactions:** Saves interactive sessions with the `TYPE_INTERACTIVE` constant so they automatically re-open in full-screen mode on load. `setInteractiveMode(enabled)` persists the active mode.
+
+### Parsing and Rendering (Dynamic UI Engine)
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/ui/dynamicui/KaiUiParser.kt`
+  - **Role:** Extracts and sanitizes the `kai-ui` JSON block using `parseUiBlockBody()`. Repairs common JSON structural errors like unclosed braces.
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/ui/dynamicui/KaiUiNodeBuilders.kt`
+  - **Role:** Uses `parseNode()` to map a `JsonElement` to `KaiUiNode` implementations with heavy fault tolerance. Drops unknown fields or unsupported types quietly.
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/ui/dynamicui/KaiUiNode.kt` & `UiAction.kt`
+  - **Role:** The serializable domain models (e.g. `ColumnNode`, `RowNode`, `ButtonNode`).
+  - **Actions:** `CallbackAction`, `ToggleAction`, `OpenUrlAction`, `CopyToClipboardAction`.
+- `composeApp/src/commonMain/kotlin/com/inspiredandroid/kai/ui/dynamicui/KaiUiRenderer.kt`
+  - **Role:** The recursive Compose rendering loop mapping `KaiUiNode` models to visual components.
+  - **Key Functions:** `KaiUiRenderer()` tracks local states (like form inputs `formState: mutableStateMapOf<String, String>()`).
+
+## Execution Flow: Callback Submit
+1. The user taps a button configured with a `CallbackAction` inside the rendered `KaiUiRenderer`.
+2. The `KaiUiRenderer` triggers the `onCallback(event, data)` lambda.
+3. This propagates to `submitUiCallback()` in `ChatViewModel`.
+4. The ViewModel formats the payload as standard text ("Pressed: $event" or "Responded with...") and submits it via `DataRepository.ask()`.
+5. If `isInteractiveMode` is active and the returning AI response lacks a `kai-ui` block, `ChatViewModel.retryIfNoValidKaiUi()` intercepts the response and prompts the AI to retry formatting as JSON.
+6. The new output flows back into the markdown pipeline, is parsed by `KaiUiParser`, and handed to `KaiUiRenderer`.

+# AGENTS.md
+
+This document outlines guidelines, environment setup, build and testing procedures, and coding standards for AI agents operating in the Kai repository.
+
+## Repository Overview
+
+Kai is a Compose Multiplatform & Kotlin Multiplatform (KMP) application supporting Android, Desktop (JVM), iOS, and Web platforms.
+
+- **Primary Repository Context**: Kai AI application
+- **Context7 Endpoint**: `https://context7.com/aeldergentics/kai`
+- **KaiSkills Sandbox Architecture**:
+  - CLI Manager Entrypoint: `python /root/kai_skills/manager.py`
+  - Skill Index: `/root/kai_skills/registry.json`
+
+---
+
+## Environment & Build Setup
+
+### Prerequisites
+- JDK 21 (configured via `JAVA_HOME` if needed)
+- Gradle wrapper (`./gradlew`)
+
+### Core Gradle Build Commands
+- **Check Spotless formatting**: `./gradlew spotlessCheck`
+- **Apply Spotless auto-formatting**: `./gradlew spotlessApply`
+- **Compile Desktop**: `./gradlew :composeApp:compileKotlinDesktop`
+- **Run Desktop Release Build**: `./gradlew :composeApp:runRelease`
+
+---
+
+## Testing Guidelines
+
+### Test Execution Commands
+- **Run full check/tests**: `./gradlew check`
+- **Run Android host tests**: `./gradlew :composeApp:testAndroidHostTest`
+- **Run specific desktop unit tests**:
+  - `ModelCatalog` tests: `./gradlew :composeApp:desktopTest --tests '*ModelCatalog*'`
+  - `FreeTierModels` tests: `./gradlew :composeApp:desktopTest --tests '*FreeTierModels*' --tests '*ModelTransformations*'`
+  - Any specific class: `./gradlew :composeApp:desktopTest --tests '<TestClassName>'`
+
+### Screenshot Testing & Generation
+- **Update README screenshots**: `./gradlew :screenshotTests:updateScreenshots`
+- **Generate store screenshots**: `./gradlew :screenshotTests:generateStoreScreenshots`
+- **Record Kai UI component screenshots**: `./gradlew :screenshotTests:recordKaiUiScreenshots`
+
+---
+
+## Coding Guidelines & Best Practices
+
+### Multiplatform (KMP) Compatibility
+- **Avoid JVM-specific methods** (e.g. `list.replaceAll`) in common code (`commonMain` / `commonTest`). Use multiplatform-compatible alternatives such as `list.map { ... }.toMutableList()`.
+- **Use `kotlin.test` for common tests**: In `commonTest`, use `kotlin.test` assertions (`kotlin.test.Test`, `kotlin.test.assertEquals`, etc.) rather than JVM-specific libraries like JUnit.
+
+### Performance & Collection Optimizations
+- **Single-pass collection operations**: Avoid chaining `.filter {}` followed by `.map {}` (or `.filterNot {}` and `.mapNotNull {}`). Collapse them into a single `.mapNotNull {}` call to evaluate conditions and transform data in a single pass, avoiding intermediate list allocations.
+
+### Code Formatting
+- Always run `./gradlew spotlessApply` after making code modifications to maintain consistent code formatting across the repository.
+
+---
+
+## Documentation & Knowledge Bundles
+
+### Feature Specifications (`docs/features/`)
+- Describe features from a product/user behavior perspective — do not include Kotlin code blocks or internal class/function names in prose.
+- When modifying feature logic:
+  1. Update the corresponding specification in `docs/features/`.
+  2. Update the "Last verified" date in the header.
+  3. Ensure the Key Files table remains accurate.
+
+### Knowledge Bundles (`docs/knowledge/`)
+Agent-curated knowledge and snapshot policies are organized as OKF-style markdown under `docs/knowledge/`:
+- `docs/knowledge/free-tier/` — paired with `FreeTierModels.kt`
+- `docs/knowledge/model-catalog/` — paired with `ModelCatalog.kt`
+- `docs/knowledge/popular-mcp/` — paired with `PopularMcpServers.kt`
+- `docs/knowledge/litert/` — paired with `LocalModelCatalog.kt`
+
+When updating knowledge snapshots, update both the markdown document and its corresponding Kotlin runtime file.
+
+---
+
+## Kai Skills Setup
+
+To install or register a new skill in the sandbox environment:
+
+```sh
+mkdir -p /root/skills/<id> && cat > /root/skills/<id>/SKILL.md <<'SKILLEOF'
+---
+name: <id>
+description: <description>
+---
+<body markdown here, verbatim>
+SKILLEOF
+```
+
+Skills are indexed in `/root/kai_skills/registry.json` and managed via `python /root/kai_skills/manager.py`.
