From 3df717e8471f859b73f3ca242e929b31f57db775 Mon Sep 17 00:00:00 2001 From: wenshao Date: Fri, 20 Mar 2026 12:19:52 +0800 Subject: [PATCH 01/82] feat(cli, webui): add follow-up suggestions feature Implement context-aware follow-up suggestions that appear after task completion, suggesting relevant next actions like "commit this", "run tests", etc. - Add `followup/` module with types, generator, and rule-based provider - Export follow-up types and functions from core index - 8 default suggestion rules covering common workflows - Add `useFollowupSuggestionsCLI` hook for Ink/React - Integrate suggestion generation in AppContainer when streaming completes - Add Tab key to accept, arrow keys to cycle through suggestions - Display suggestions as ghost text in input prompt - Add `useFollowupSuggestions` hook for React - Update InputForm to display suggestions as placeholder - Add CSS styling for suggestion appearance with counter - Add keyboard handlers (Tab, arrow keys) - After streaming completes with tool calls, suggestions appear - Tab accepts the current suggestion - Left/Right arrows cycle through multiple suggestions - Typing or pasting dismisses the suggestion - Shell command rules (tests, git, npm install) don't work yet due to history not storing tool arguments - VSCode extension integration pending - Web UI needs parent app integration for suggestion generation Co-Authored-By: Claude Opus 4.6 --- packages/cli/src/ui/AppContainer.tsx | 102 ++++++ packages/cli/src/ui/components/Composer.tsx | 1 + .../cli/src/ui/components/InputPrompt.tsx | 208 +++++++++++- .../cli/src/ui/contexts/UIStateContext.tsx | 4 +- .../src/ui/hooks/useFollowupSuggestions.tsx | 269 +++++++++++++++ packages/core/src/followup/index.ts | 13 + .../core/src/followup/ruleBasedProvider.ts | 303 +++++++++++++++++ .../core/src/followup/suggestionGenerator.ts | 145 +++++++++ packages/core/src/followup/types.ts | 112 +++++++ packages/core/src/index.ts | 6 + .../webui/src/components/layout/InputForm.tsx | 81 ++++- .../webui/src/hooks/useFollowupSuggestions.ts | 307 ++++++++++++++++++ packages/webui/src/index.ts | 8 + packages/webui/src/styles/components.css | 32 ++ 14 files changed, 1587 insertions(+), 4 deletions(-) create mode 100644 packages/cli/src/ui/hooks/useFollowupSuggestions.tsx create mode 100644 packages/core/src/followup/index.ts create mode 100644 packages/core/src/followup/ruleBasedProvider.ts create mode 100644 packages/core/src/followup/suggestionGenerator.ts create mode 100644 packages/core/src/followup/types.ts create mode 100644 packages/webui/src/hooks/useFollowupSuggestions.ts diff --git a/packages/cli/src/ui/AppContainer.tsx b/packages/cli/src/ui/AppContainer.tsx index 2574f5bf0c3..da78172539b 100644 --- a/packages/cli/src/ui/AppContainer.tsx +++ b/packages/cli/src/ui/AppContainer.tsx @@ -41,6 +41,9 @@ import { Storage, SessionEndReason, SessionStartSource, + getGenerator, + extractSuggestionContext, + type FollowupSuggestion, } from '@qwen-code/qwen-code-core'; import { buildResumedHistoryItems } from './utils/resumeHistoryUtils.js'; import { validateAuthMethod } from '../config/auth.js'; @@ -720,6 +723,12 @@ export const AppContainer = (props: AppContainerProps) => { const agentViewState = useAgentViewState(); + // Follow-up suggestions state + const [followupSuggestions, setFollowupSuggestions] = useState< + FollowupSuggestion[] + >([]); + const prevStreamingStateRef = useRef(StreamingState.Idle); + // Auto-accept indicator — disabled on agent tabs (agents handle their own) const showAutoAcceptIndicator = useAutoAcceptIndicator({ config, @@ -913,6 +922,95 @@ export const AppContainer = (props: AppContainerProps) => { geminiClient, ]); + // Generate follow-up suggestions when streaming completes + useEffect(() => { + // Only trigger when transitioning from Responding to Idle + if ( + prevStreamingStateRef.current === StreamingState.Responding && + streamingState === StreamingState.Idle + ) { + // Get the last gemini message from history + const history = historyManager.history; + + // Also check tool_group items in history (these are preserved) + const toolGroupItems = history.filter( + (item) => item.type === 'tool_group', + ); + + // Generate suggestions even if pendingToolCalls is empty - use history instead + const toolCalls = toolGroupItems + .slice(-10) // Get last 10 tool calls + .map((item) => { + const toolGroup = item as { + tools?: Array<{ name: string; status: ToolCallStatus }>; + }; + if (toolGroup.tools) { + return toolGroup.tools.map((tool) => ({ + name: tool.name, + input: {} as Record, // History doesn't store args + status: + tool.status === ToolCallStatus.Success + ?

Core changes: - Replace ruleBasedProvider with generatePromptSuggestion using BaseLlmClient.generateJson() - Port Claude Code's SUGGESTION_PROMPT and 14 filter rules (shouldFilterSuggestion) - Simplify state from multi-suggestion array to single string (FollowupState) - Add framework-agnostic controller with Object.freeze'd initial state Guard conditions (9 checks): - Settings toggle, non-interactive/SDK mode, plan mode - Permission/confirmation/loop-detection dialogs, elicitation requests - API error response detection, conversation history limit (slice -40) UI interaction (CLI + WebUI): - Tab: fill suggestion into input - Enter: accept and submit - Right Arrow: fill without submitting - Typing/paste: dismiss suggestion - Autocomplete conflict prevention Telemetry (PromptSuggestionEvent): - outcome (accepted/ignored/suppressed), accept_method (tab/enter/right) - time_to_accept_ms, time_to_ignore_ms, time_to_first_keystroke_ms - suggestion_length, similarity, was_focused_when_shown, prompt_id - Per-rule suppression logging with reason strings Deleted files: - ruleBasedProvider.ts/test, followupHistory.ts/test, types.ts (dead FollowupSuggestion type) 13 rounds of adversarial audit, 17 issues found and fixed.
