## 1. agents/

The agents subsystem provides a full UI for creating, viewing, editing, deleting, and listing custom Claude sub-agents (stored as Markdown files with YAML front matter in `.claude/agents/`).

### 1.1 AgentDetail

**File:** `agents/AgentDetail.tsx`

**Purpose:** Renders a read-only detail view of a single `AgentDefinition`, showing all agent metadata (file path, description, tools, model, permission mode, memory, hooks, skills, color swatch, and system prompt for non-built-in agents).

**Props Interface:**
```typescript
type Props = {
  agent: AgentDefinition;      // The agent to display
  tools: Tools;                // All available tools (for resolving tool names)
  allAgents?: AgentDefinition[]; // All agents (unused in current render, passed for context)
  onBack: () => void;          // Called when user presses Esc or Enter
}
```

**Key Behaviors:**
- Resolves tool list via `resolveAgentTools(agent, tools, false)` — shows "All tools", named valid tools, and warns about unrecognized tool names with a warning symbol.
- Computes `backgroundColor` from `getAgentColor(agent.agentType)` for the color swatch preview.
- Binds `confirm:no` keybinding in Confirmation context to call `onBack`.
- Binds `return` keypress to `onBack`.
- Renders system prompt via `<Markdown>` only for non-built-in agents (`!isBuiltInAgent(agent)`).
- Displays model via `getAgentModelDisplay(agent.model)`.
- Displays memory via `getMemoryScopeDisplay(agent.memory)`.
- Displays skills count inline when > 10 entries.

**Exports:** `AgentDetail`

---

### 1.2 AgentEditor

**File:** `agents/AgentEditor.tsx`

**Purpose:** Full-screen editor for modifying an existing `AgentDefinition`. Supports editing the agent type (name), system prompt, description (whenToUse), tools, model, color, memory, and effort. Persists changes by calling `updateAgentFile`. Provides a step-by-step editing flow using a sub-state machine.

**Props Interface:** (large component; reconstructed from source)
```typescript
type Props = {
  agent: AgentDefinition;          // The agent to edit
  tools: Tools;                    // All available tools
  existingAgents: AgentDefinition[]; // For duplicate-name validation
  onComplete: (message: string) => void; // Called after successful save
  onCancel: () => void;            // Called when user cancels
}
```

**Key Behaviors:**
- Multi-step flow: main edit menu → individual field editors (each with their own step).
- Edit menu shows: Edit system prompt, Edit description, Select tools, Select model, Choose color, (conditional) Choose memory, Back.
- Each field editor reuses the same sub-components used in wizard steps (ToolSelector, ModelSelector, ColorPicker, etc.).
- On save calls `updateAgentFile(agent, ...)` and reloads agent state in app state.
- Validates agent type via `validateAgentType()` before allowing name changes.
- Uses React compiler memoization throughout.

**Exports:** `AgentEditor`

---

### 1.3 AgentNavigationFooter

**File:** `agents/AgentNavigationFooter.tsx`

**Purpose:** Renders a dimmed footer line with keyboard navigation instructions. Integrates with Ctrl+C/D exit state to show "Press X again to exit" during double-tap detection.

**Props Interface:**
```typescript
type Props = {
  instructions?: string;
  // Default: "Press ↑↓ to navigate · Enter to select · Esc to go back"
}
```

**Key Behaviors:**
- Calls `useExitOnCtrlCDWithKeybindings()` to detect pending exit.
- When `exitState.pending` is true, overrides instruction text with `"Press ${exitState.keyName} again to exit"`.
- Renders with `marginLeft={2}` and `dimColor`.

**Exports:** `AgentNavigationFooter`

---

### 1.4 AgentsList

**File:** `agents/AgentsList.tsx`

**Purpose:** Displays a list of agents for a given source (all, built-in, userSettings, projectSettings, etc.), grouped by source category. Supports keyboard navigation, optional "Create new agent" entry, and shows override warnings when an agent is shadowed by another scope.

**Props Interface:**
```typescript
type Props = {
  source: SettingSource | 'all' | 'built-in' | 'plugin';
  agents: ResolvedAgent[];           // Agents resolved with override info
  onBack: () => void;
  onSelect: (agent: AgentDefinition) => void;
  onCreateNew?: () => void;          // If provided, shows "Create new agent" option at top
  changes?: string[];                // Recent change messages to display
}
```

**Key Behaviors:**
- State: `selectedAgent` (currently highlighted agent), `isCreateNewSelected` (boolean, focuses "Create new agent").
- Auto-selects first agent or "Create new" if nothing selected.
- `handleKeyDown`: Up/Down arrows navigate the list (wraps around). Enter activates selected item.
- Groups agents by source using `AGENT_SOURCE_GROUPS`.
- Built-in agents are rendered separately with `renderBuiltInAgentsSection()` (dimmed, no pointer).
- Per-agent display: name, optional model display (middot-separated), memory label, override shadow warning.
- Shadowed agents shown dimmed with a warning symbol (`figures.warning`) and "shadowed by X" text.
- Changes list shown at top with success color.

**Exports:** `AgentsList`

---

### 1.5 AgentsMenu

**File:** `agents/AgentsMenu.tsx`

**Purpose:** Top-level orchestrator for the agents management UI. Implements a state machine with modes: `list-agents`, `create-agent`, `agent-menu`, `view-agent`, `edit-agent`, `delete-confirm`. Reads/writes app state for agent definitions.

**Props Interface:**
```typescript
type Props = {
  tools: Tools;
  onExit: (result?: string, options?: { display?: CommandResultDisplay }) => void;
}
```

**Key Behaviors:**
- `modeState` union type discriminated by `mode` field.
- Reads `agentDefinitions`, `mcpTools`, `toolPermissionContext` from app state.
- Merges tools via `useMergedTools()`.
- Groups agents into 8 buckets by source (built-in, userSettings, projectSettings, policySettings, localSettings, flagSettings, plugin, all).
- Resolves display-time overrides via `resolveAgentOverrides()`.
- `handleAgentCreated`: adds change message, returns to list-agents/all view.
- `handleAgentDeleted`: calls `deleteAgentFromFile()`, updates app state, adds change message.
- In `agent-menu` mode: renders a `<Select>` with options View / Edit (if editable) / Delete (if editable) / Back. Editability requires `source` not in `['built-in', 'plugin', 'flagSettings']`.
- In `delete-confirm` mode: shows a confirmation `<Dialog>` with Yes/No options.
- On exit: formats change summary or "Agents dialog dismissed" system message.

**Exports:** `AgentsMenu`

---

### 1.6 ColorPicker

**File:** `agents/ColorPicker.tsx`

**Purpose:** Interactive color selector for agent type color. Displays all `AGENT_COLORS` plus an "Automatic color" option. Shows a live preview of the color applied to the agent name.

**Props Interface:**
```typescript
type Props = {
  agentName: string;                           // For preview display
  currentColor?: AgentColorName | 'automatic';  // Pre-selected color
  onConfirm: (color: AgentColorName | undefined) => void; // undefined = automatic
}
```

**Key Behaviors:**
- `COLOR_OPTIONS = ['automatic', ...AGENT_COLORS]`.
- State: `selectedIndex` initialized from `currentColor` or 0.
- Up/Down arrow keys navigate; Enter confirms. `'automatic'` selection calls `onConfirm(undefined)`.
- Preview box shows agent name with background color or inverse styling.
- Uses `AGENT_COLOR_TO_THEME_COLOR` for actual terminal color values.

**Exports:** `ColorPicker`

---

### 1.7 ModelSelector

**File:** `agents/ModelSelector.tsx`

**Purpose:** Renders a `<Select>` component for choosing an agent model from the standard list (`getAgentModelOptions()`). Injects the current model as a custom option if it is a full model ID not in the standard alias list.

**Props Interface:**
```typescript
interface ModelSelectorProps {
  initialModel?: string;                     // Current model value
  onComplete: (model?: string) => void;      // Called with selected model
  onCancel?: () => void;                     // If absent, cancel calls onComplete(undefined)
}
```

**Key Behaviors:**
- If `initialModel` is not in the standard options list, prepends `{ value: initialModel, label: initialModel, description: "Current model (custom ID)" }`.
- Default value: `initialModel ?? 'sonnet'`.
- Cancel: calls `onCancel()` if provided, otherwise `onComplete(undefined)`.
- Renders a description line: "Model determines the agent's reasoning capabilities and speed."

**Exports:** `ModelSelector`

---

### 1.8 ToolSelector

**File:** `agents/ToolSelector.tsx`

**Purpose:** Multi-select UI for choosing which tools an agent can access. Groups tools into buckets: Read-only, Edit, Execution, MCP (per-server), and Other. Supports "All tools" wildcard selection.

**Props Interface:**
```typescript
type Props = {
  tools: Tools;                                        // All available tools
  initialTools: string[] | undefined;                  // Pre-selected tool names (undefined = all)
  onComplete: (selectedTools: string[] | undefined) => void; // undefined = all tools
  onCancel?: () => void;
}

type ToolBucket = {
  name: string;
  toolNames: Set<string>;
  isMcp?: boolean;
};

type ToolBuckets = {
  READ_ONLY: ToolBucket;  // GlobTool, GrepTool, FileReadTool, WebFetchTool, etc.
  EDIT: ToolBucket;       // FileEditTool, FileWriteTool, NotebookEditTool
  EXECUTION: ToolBucket;  // BashTool, (TungstenTool for internal builds)
  MCP: ToolBucket;        // Dynamic, populated per MCP server
  OTHER: ToolBucket;      // Uncategorized catch-all
};
```

**Key Behaviors:**
- MCP tools grouped dynamically by server name via `getMcpServerBuckets()`.
- Tools not matching any bucket go into OTHER.
- AGENT_TOOL_NAME excluded from selectable tools.
- Toggle selection per individual tool; "Select all" / "Deselect all" shortcuts within buckets.
- Up/Down navigation; Space/Enter toggle; Tab/Shift+Tab move between buckets.
- On submit: if no tools selected and wildcard not set, passes empty array. Pressing a confirm shortcut with no selection can also pass `undefined` (all tools).

**Exports:** `ToolSelector`

---

### 1.9 agentFileUtils.ts

**File:** `agents/agentFileUtils.ts`

**Purpose:** File system utility functions for reading and writing agent definition Markdown files.

**Exports:**

```typescript
// Formats agent fields into a Markdown file with YAML front matter
function formatAgentAsMarkdown(
  agentType: string,
  whenToUse: string,
  tools: string[] | undefined,
  systemPrompt: string,
  color?: string,
  model?: string,
  memory?: AgentMemoryScope,
  effort?: EffortValue,
): string

// Returns the absolute directory for an agent based on source
function getAgentDirectoryPath(location: SettingSource): string  // (private)

// Returns relative directory path for display
function getRelativeAgentDirectoryPath(location: SettingSource): string  // (private)

// Path for a NEW agent file (uses agentType as filename)
function getNewAgentFilePath(agent: { source: SettingSource; agentType: string }): string

// Path for an EXISTING agent (uses actual filename if different from agentType)
function getActualAgentFilePath(agent: AgentDefinition): string

// Relative path for new agent display
function getNewRelativeAgentFilePath(agent: { source: SettingSource | 'built-in'; agentType: string }): string

// Relative path for existing agent display (handles built-in/plugin/flagSettings)
function getActualRelativeAgentFilePath(agent: AgentDefinition): string

// Ensures directory exists then writes agent file
async function saveAgentToFile(
  source: SettingSource | 'built-in',
  agentType: string,
  whenToUse: string,
  tools: string[] | undefined,
  systemPrompt: string,
  checkExists?: boolean,     // default true — throws EEXIST if file already exists
  color?: string,
  model?: string,
  memory?: AgentMemoryScope,
  effort?: EffortValue,
): Promise<void>

// Overwrites an existing agent's file
async function updateAgentFile(
  agent: AgentDefinition,
  newWhenToUse: string,
  newTools: string[] | undefined,
  newSystemPrompt: string,
  newColor?: string,
  newModel?: string,
  newMemory?: AgentMemoryScope,
  newEffort?: EffortValue,
): Promise<void>

// Removes the agent's file (ignores ENOENT)
async function deleteAgentFromFile(agent: AgentDefinition): Promise<void>
```

**Key Behaviors:**
- All writes use `writeFileAndFlush` which calls `handle.datasync()` after writing for durability.
- `formatAgentAsMarkdown` escapes backslashes, double quotes, and newlines in `whenToUse` for YAML double-quoted strings.
- Tools field omitted entirely when `undefined` or `['*']` (means all tools allowed).

---

### 1.10 generateAgent.ts

**File:** `agents/generateAgent.ts`

**Purpose:** Uses an LLM call (`queryModelWithoutStreaming`) to auto-generate an agent configuration from a natural language user prompt. Returns `identifier`, `whenToUse`, and `systemPrompt` as structured JSON.

**Exports:**
```typescript
type GeneratedAgent = {
  identifier: string
  whenToUse: string
  systemPrompt: string
}

async function generateAgent(
  userPrompt: string,
  model: ModelName,
  existingIdentifiers: string[],  // Blocked identifiers included in prompt
  abortSignal: AbortSignal,
): Promise<GeneratedAgent>
```

**Key Behaviors:**
- Uses a detailed system prompt (`AGENT_CREATION_SYSTEM_PROMPT`) instructing Claude on how to design agent personas, write system prompts, create identifiers (lowercase, 2-4 words, hyphens only, no "helper"/"assistant").
- When `isAutoMemoryEnabled()`, appends `AGENT_MEMORY_INSTRUCTIONS` to the system prompt.
- Prepends user context via `prependUserContext()`.
- Parses JSON from response — falls back to regex extraction if direct parse fails.
- Fires `tengu_agent_definition_generated` analytics event.
- Throws on invalid/missing fields.

---

### 1.11 types.ts

**File:** `agents/types.ts`

**Purpose:** Shared type definitions for the agents UI state machine.

**Exports:**
```typescript
const AGENT_PATHS = {
  FOLDER_NAME: '.claude',
  AGENTS_DIR: 'agents',
} as const

type ModeState =
  | { mode: 'main-menu' }
  | { mode: 'list-agents'; source: SettingSource | 'all' | 'built-in' }
  | { mode: 'agent-menu'; agent: AgentDefinition; previousMode: ModeState }
  | { mode: 'view-agent'; agent: AgentDefinition; previousMode: ModeState }
  | { mode: 'create-agent' }
  | { mode: 'edit-agent'; agent: AgentDefinition; previousMode: ModeState }
  | { mode: 'delete-confirm'; agent: AgentDefinition; previousMode: ModeState }

type AgentValidationResult = {
  isValid: boolean
  warnings: string[]
  errors: string[]
}
```

---

### 1.12 utils.ts

**File:** `agents/utils.ts`

**Exports:**
```typescript
function getAgentSourceDisplayName(
  source: SettingSource | 'all' | 'built-in' | 'plugin'
): string
// Returns: 'Agents' | 'Built-in agents' | 'Plugin agents' | capitalize(getSettingSourceName(source))
```

---

### 1.13 validateAgent.ts

**File:** `agents/validateAgent.ts`

**Exports:**
```typescript
type AgentValidationResult = {
  isValid: boolean
  errors: string[]
  warnings: string[]
}

function validateAgentType(agentType: string): string | null
// Returns error message or null if valid.
// Rules: required, /^[a-zA-Z0-9][a-zA-Z0-9-]*[a-zA-Z0-9]$/, length 3-50 chars.

function validateAgent(
  agent: Omit<CustomAgentDefinition, 'location'>,
  availableTools: Tools,
  existingAgents: AgentDefinition[],
): AgentValidationResult
// Validates: agentType, whenToUse (min 10 chars / max 5000), tools array,
// system prompt (min 20 chars / max 10000 chars warning threshold).
// Checks for duplicate agentType across sources.
// Uses resolveAgentTools to check for invalid tool names.
```

---

### 1.14 new-agent-creation/CreateAgentWizard

**File:** `agents/new-agent-creation/CreateAgentWizard.tsx`

**Purpose:** Assembles the multi-step new-agent creation wizard by composing step components inside `<WizardProvider>`. Conditionally includes `MemoryStep` based on feature flag.

**Props Interface:**
```typescript
type Props = {
  tools: Tools;
  existingAgents: AgentDefinition[];
  onComplete: (message: string) => void;
  onCancel: () => void;
}
```

**Wizard Step Order (0-indexed):**
0. `LocationStep` — project vs personal scope
1. `MethodStep` — generate with Claude vs manual
2. `GenerateStep` — natural language prompt → LLM generation (skipped for manual)
3. `TypeStep` — agent identifier / name
4. `PromptStep` — system prompt text
5. `DescriptionStep` — whenToUse description
6. `ToolsStep` — tool selection
7. `ModelStep` — model selection
8. `ColorStep` — color selection
9. `MemoryStep` — memory scope (conditional on `isAutoMemoryEnabled()`)
10. `ConfirmStepWrapper` — review and save

**Key Behaviors:**
- WizardProvider title: "Create new agent", `showStepCounter: false`.
- `onComplete` of WizardProvider is a no-op (actual completion handled by `ConfirmStepWrapper`).
- Passes `onCancel` through to WizardProvider.

---

### 1.15 Wizard Steps

#### LocationStep
Offers two options: "Project (.claude/agents/)" (`projectSettings`) or "Personal (~/.claude/agents/)" (`userSettings`). Updates `wizardData.location` and calls `goNext()`.

#### MethodStep
Offers "Generate with Claude (recommended)" or "Manual configuration". For generate: sets `wizardData.method = 'generate'`, `wasGenerated: true`, `goNext()`. For manual: sets `method: 'manual'`, `wasGenerated: false`, skips to step 3 via `goToStep(3)`.

#### GenerateStep
- Text input for natural language description of the agent.
- On submit: calls `generateAgent(prompt, model, existingIdentifiers, abortSignal)`.
- Shows animated `<Spinner>` during generation.
- On success: populates `wizardData.agentType`, `systemPrompt`, `whenToUse`, `generatedAgent`.
- Navigates directly to step 6 (ToolsStep) after generation (skips manual name/prompt/description steps).
- Esc during generation cancels via abort signal.
- Supports external editor (`chat:externalEditor` keybinding).

#### TypeStep
Props: `{ existingAgents: AgentDefinition[] }`. Text input for agent identifier. Validates via `validateAgentType()`. Updates `wizardData.agentType`.

#### PromptStep
Large text input for system prompt. Min 20 chars enforced. Supports external editor. Updates `wizardData.systemPrompt`.

#### DescriptionStep
Text input for `whenToUse`. Required, min 1 char. Supports external editor. Updates `wizardData.whenToUse`.

#### ToolsStep
Props: `{ tools: Tools }`. Wraps `<ToolSelector>` in `WizardDialogLayout`. Updates `wizardData.selectedTools`.

#### ModelStep
Wraps `<ModelSelector>` in `WizardDialogLayout`. Updates `wizardData.selectedModel`.

#### ColorStep
Wraps `<ColorPicker>` in `WizardDialogLayout`. On confirm: builds `wizardData.finalAgent` object with all accumulated data, updates `wizardData.selectedColor`.

#### MemoryStep
Conditional step (only shown when `isAutoMemoryEnabled()`). Offers memory scope options ordered by recommended scope (project-first for project agents, user-first for personal agents). Includes "None" option. Updates `wizardData.selectedMemory`.

#### ConfirmStep / ConfirmStepWrapper
Props: `{ tools: Tools; existingAgents: AgentDefinition[]; onComplete: (message: string) => void }`. Shows a summary of all selected options, validates via `validateAgent()`, calls `saveAgentToFile()`, then reloads agents in app state and calls `onComplete(message)`.

---

## 2. permissions/

The permissions subsystem renders interactive dialogs asking users to approve, reject, or configure rules for tool uses. Each tool has its own permission request component.

### 2.1 Core Types & PermissionRequest

**File:** `permissions/PermissionRequest.tsx`

**Purpose:** Top-level dispatcher that picks the correct permission request component for each tool type and renders it. Also handles notifications and idle detection.

**Key Types:**
```typescript
type PermissionRequestProps<Input extends AnyObject = AnyObject> = {
  toolUseConfirm: ToolUseConfirm<Input>;
  toolUseContext: ToolUseContext;
  onDone(): void;
  onReject(): void;
  verbose: boolean;
  workerBadge: WorkerBadgeProps | undefined;
  setStickyFooter?: (jsx: React.ReactNode | null) => void;
  // Registers JSX in a sticky footer below scrollable area (fullscreen only).
}

type ToolUseConfirm<Input extends AnyObject = AnyObject> = {
  assistantMessage: AssistantMessage;
  tool: Tool<Input>;
  description: string;
  input: z.infer<Input>;
  toolUseContext: ToolUseContext;
  toolUseID: string;
  permissionResult: PermissionDecision;
  permissionPromptStartTimeMs: number;
  classifierCheckInProgress?: boolean;
  classifierAutoApproved?: boolean;
  classifierMatchedRule?: string;
  workerBadge?: WorkerBadgeProps;
  onUserInteraction(): void;
  onAbort(): void;
  onDismissCheckmark?(): void;
  onAllow(updatedInput, permissionUpdates: PermissionUpdate[], feedback?, contentBlocks?): void;
  onReject(feedback?, contentBlocks?): void;
  recheckPermission(): Promise<void>;
}
```

**Tool→Component Mapping:**
| Tool | Component |
|------|-----------|
| FileEditTool | FileEditPermissionRequest |
| FileWriteTool | FileWritePermissionRequest |
| BashTool | BashPermissionRequest |
| PowerShellTool | PowerShellPermissionRequest |
| WebFetchTool | WebFetchPermissionRequest |
| NotebookEditTool | NotebookEditPermissionRequest |
| ExitPlanModeV2Tool | ExitPlanModePermissionRequest |
| EnterPlanModeTool | EnterPlanModePermissionRequest |
| SkillTool | SkillPermissionRequest |
| AskUserQuestionTool | AskUserQuestionPermissionRequest |
| GlobTool / GrepTool / FileReadTool | FilesystemPermissionRequest |
| ReviewArtifactTool (feature flag) | ReviewArtifactPermissionRequest |
| WorkflowTool (feature flag) | WorkflowPermissionRequest |
| MonitorTool (feature flag) | MonitorPermissionRequest |
| default | FallbackPermissionRequest |

**Exports:** `PermissionRequest`, `PermissionRequestProps`, `ToolUseConfirm`

---

### 2.2 PermissionDialog

**File:** `permissions/PermissionDialog.tsx`

**Purpose:** The shared visual container for all tool permission requests. Renders a title bar (with optional worker badge), subtitle, and children, wrapped in a styled border box.

**Props Interface:**
```typescript
type Props = {
  title: string;
  subtitle?: React.ReactNode;
  color?: keyof Theme;          // default: 'permission'
  titleColor?: keyof Theme;
  innerPaddingX?: number;       // default: 1
  workerBadge?: WorkerBadgeProps;
  titleRight?: React.ReactNode; // Right-aligned content in title row
  children: React.ReactNode;
}
```

**Key Behaviors:**
- Renders `<PermissionRequestTitle>` with the title, subtitle, optional color override, and workerBadge.
- Title row uses `justifyContent="space-between"` to place `titleRight` on the right.
- Children rendered in inner `Box` with `paddingX={innerPaddingX}`.

**Exports:** `PermissionDialog`

---

### 2.3 BashPermissionRequest

**File:** `permissions/BashPermissionRequest/BashPermissionRequest.tsx`

**Purpose:** Permission dialog for `BashTool`. Handles classifier-based auto-approval animation, sed edit detection (redirects to `SedEditPermissionRequest`), sandbox detection, and a rich set of options.

**Key Behaviors:**
- `ClassifierCheckingSubtitle`: separate sub-component that renders an animated shimmer "Attempting to auto-approve…" text at 20fps, isolated to prevent full-dialog re-renders.
- Checks `classifierCheckInProgress` prop — shows shimmer subtitle while classifier runs.
- If command matches a `sed` edit pattern, delegates to `SedEditPermissionRequest`.
- If `shouldUseSandbox()`, shows sandbox-specific options.
- Options computed by `bashToolUseOptions()`.
- Logs permission decision via `usePermissionRequestLogging()`.
- Supports destructive command warning display.

**Exports:** `BashPermissionRequest`

---

### 2.4 FilePermissionDialog

**File:** `permissions/FilePermissionDialog/FilePermissionDialog.tsx`

**Purpose:** Generic reusable dialog for file-operation permissions (used by FileEdit, FileWrite, NotebookEdit permission requests). Handles path display, symlink detection, IDE diff integration, and option rendering.

**Props Interface:**
```typescript
type FilePermissionDialogProps<T extends ToolInput = ToolInput> = {
  toolUseConfirm: ToolUseConfirm;
  toolUseContext: ToolUseContext;
  onDone: () => void;
  onReject: () => void;
  title: string;
  subtitle?: React.ReactNode;
  question?: string | React.ReactNode;   // default: 'Do you want to proceed?'
  content?: React.ReactNode;
  completionType?: CompletionType;       // default: 'tool_use_single'
  languageName?: string;                 // Overrides path-derived language name
  path: string | null;
  parseInput: (input: unknown) => T;
  operationType?: FileOperationType;     // default: 'write'
  ideDiffSupport?: IDEDiffSupport<T>;
  workerBadge: WorkerBadgeProps | undefined;
}
```

**Key Behaviors:**
- Language name derived async from `getLanguageName(path)` if not overridden.
- Checks for symlink target when `operationType !== 'read'`.
- Shows `<ShowInIDEPrompt>` when IDE diff is available.
- Logs via `usePermissionRequestLogging()`.

**Exports:** `FilePermissionDialog`, `FilePermissionDialogProps`

---

### 2.5 WorkerBadge

**File:** `permissions/WorkerBadge.tsx`

**Purpose:** Colored badge showing which swarm worker is requesting a permission.

**Props Interface:**
```typescript
type WorkerBadgeProps = {
  name: string;    // Worker name (shown as @name)
  color: string;   // Raw color string (converted to Ink color via toInkColor)
}
```

**Rendering:** `● @{name}` with the bullet in the worker's color.

**Exports:** `WorkerBadge`, `WorkerBadgeProps`

---

### 2.6 Other Permission Request Components

Each follows the `PermissionRequestProps` interface and renders inside `<PermissionDialog>` or `<FilePermissionDialog>`.

#### FileEditPermissionRequest
Renders a diff of the proposed file edit. Uses `FilePermissionDialog` with diff content component. `operationType: 'write'`.

#### FileWritePermissionRequest
Renders the full proposed file content. Uses `FilePermissionDialog`. `operationType: 'write'`.

#### FilesystemPermissionRequest
For GlobTool / GrepTool / FileReadTool. Shows a read-only access dialog. `operationType: 'read'`.

#### NotebookEditPermissionRequest
For Jupyter notebook edits. Renders a notebook cell diff. Uses `FilePermissionDialog` with `languageName` derived from cell type.

#### WebFetchPermissionRequest
Shows the URL being fetched and fetch options.

#### PowerShellPermissionRequest
Similar to BashPermissionRequest but for PowerShell commands. Uses `powershellToolUseOptions()`.

#### SedEditPermissionRequest
Rendered by BashPermissionRequest when sed-edit pattern is detected. Shows the file diff that the sed command would produce.

  goBack: () => void;
  goToStep: (index: number) => void;
  cancel: () => void;
  title: string | undefined;
  showStepCounter: boolean;
}
```

**Key Behaviors:**

## Cross-Cutting Patterns

### React Compiler Memoization
All components use `import { c as _c } from "react/compiler-runtime"` and the `$` cache array pattern for React Compiler auto-memoization. This is a build-time transformation — the source TypeScript uses standard React patterns.

### Theme Integration
- All color props accept `keyof Theme` (semantic tokens like `'permission'`, `'suggestion'`, `'success'`, `'error'`, `'warning'`, `'inactive'`) or raw CSS color strings.
- `ThemedBox` and `ThemedText` resolve theme tokens to raw colors at render time via `useTheme()`.

### Keybinding System
- Components use `useKeybinding(action, handler, { context, isActive })` from `../../keybindings/useKeybinding.js`.
- Contexts: `'Confirmation'`, `'Settings'`, `'Chat'`, `'Application'`.
- Standard actions: `'confirm:no'` (Esc/N), `'app:exit'` (Ctrl+C), `'app:interrupt'` (Ctrl+D).

### Permission Flow
1. Tool use triggers permission check → `PermissionResult` with behavior `'ask'` / `'allow'` / `'deny'` / `'passthrough'`.
2. `'ask'` behavior → `ToolUseConfirm` object created → `PermissionRequest` component rendered.
3. User selects option → `onAllow(updatedInput, permissionUpdates)` or `onReject(feedback)` called.
4. Permission updates stored in settings for future auto-approval.

### Wizard Pattern
1. `WizardProvider` holds step array and accumulated data.
2. Each step calls `useWizard()` to get navigation functions.
3. Steps call `updateWizardData(partial)` then `goNext()` / `goToStep(n)`.
4. Final step calls external `onComplete(message)` directly (not via wizard's `onComplete`).

### Agent File Format
