Adds vector-based semantic search across all chat sessions using Qdrant.
When a ChatTurn finishes, its content is chunked, embedded, and upserted
to a Qdrant collection. A search API and UI components enable searching
at user, project, and session scope.
Phase 1 — Configuration & Dependencies
- Add port/apiKey to GadgetCodeConfig.qdrant type
- Uncomment and update qdrant section in YAML config example
- Add qdrant config passthrough in env.ts
- Add @qdrant/js-client-rest dependency
Phase 2 — AI Embedding API (@gadget/ai)
- Add IAiEmbeddingResponse interface and abstract embeddings() to AiApi
- Implement embeddings() in OllamaAiApi (client.embeddings)
- Implement embeddings() in OpenAiApi (client.embeddings.create)
- Export IAiEmbeddingResponse from package index
Phase 3 — Backend Vector Store Service
- Create VectorStoreService (ingestTurn, search, removeTurnPoints)
- Hook fire-and-forget ingest after turn.save() in drone-session
- Register VectorStoreService in service startup/shutdown
Phase 4 — Backend Search API
- Create POST /api/v1/search controller with userId enforcement
- Batch-hydrate results from MongoDB (user, project, session, turn)
- Register search route in v1 API router
Phase 5 — Frontend Search Components
- SearchInput: debounced input with lucide-react icons
- ChatSearchResults: modal with score badges, metadata, loading states
- DroneSelectionModal: drone picker for sessions without a drone
- Add searchApi and ISearchResult to API client
- Add search to Home (global), ProjectManager (project), ChatSessionView (session)
- Add id=turn-{turnId} to ChatTurn for scroll targeting
- Scroll-to-turn from search result selection and router state
- Show DroneSelectionModal when no drone available
- Add Select Drone button in ChatSessionView sidebar
Phase 1: OpenAI API Token Extraction
- Add stream_options: { include_usage: true } to all streaming API calls
- Capture chunk.usage from final streaming chunks and response.usage from non-streaming
- Extend OpenAiChatIterationResult with optional usage field
- Update buildStats() to accept and return real token counts from usage data
- Wire iteration.usage through chat() to both buildStats() call sites
Phase 2: Agent Loop Stats Propagation
- Rename inputTokens/outputTokens to masterInputTokens/masterOutputTokens, add masterThinkingTokens
- Accumulate response.stats.tokenCounts after each master AI call
- Delete all Math.ceil(length/4) crude approximations (master and subagent loops)
- Track startTime/durationMs and emit IWorkOrderCompleteStats with workOrderComplete
- Subagent loop uses response.stats?.tokenCounts instead of Math.ceil
Phase 3: Database Model Changes
- Add contextWindowUsage field to IChatSession, ChatSessionSchema, and frontend ChatSession
- Initialize contextWindowUsage: 0 on session creation
Phase 4: Persist Stats on Turn Completion
- drone-session: accept IWorkOrderCompleteStats, persist turn stats, walk subagent records for aggregate
- drone-session: $inc session stats and contextWindowUsage, add formatDurationLabel() helper
- code-session: accept and forward stats, update in-memory session stats
- message-queue: Redis replay handles 4th stats arg
- Update WorkOrderCompleteMessage type in @gadget/api to accept stats parameter
Phase 5: UI — Context Window Fuel Gauge
- Add contextWindowUsage prop to SessionPanel
- Add fuel gauge bar with E→F labels, green/yellow/red zones, token count display
- Visible for ALL provider types (not gated by apiType)
Phase 6: Frontend Streaming State
- Add IWorkOrderCompleteStats interface to frontend api.ts
- handleWorkOrderComplete accepts stats, updates turn stats and session contextWindowUsage
- Pass contextWindowUsage prop to SessionPanel
Plan tools extended to all modes; recent chat sessions added to
Authenticated Home view; drone locking and chat session startup factored
out of Project Manager into Chat Session view and made universal; update
for AGENTS.md.
- IChatSession/IChatTurn interfaces: add optional numCtx field
- Mongoose schemas: add numCtx field to ChatSession and ChatTurn
- API controller: validate numCtx (>=16384, multiple of 8192)
- ChatSessionService: persist numCtx on session, pass through to turn
- SessionPanel: add range slider for Context Window (hidden for OpenAI)
- Drone buildDroneModelConfig: prefer turn.numCtx over model defaults
The editor was overflowing its container because @uiw/react-codemirror
renders a wrapper div that doesn't inherit flex constraints by default.
Fixed by adding CSS rules that:
1. Set overflow:hidden on .cm-editor-container
2. Target the wrapper div (> div) with flex:1, min-height:0, overflow:hidden
3. Set .cm-editor and .cm-scroller to overflow appropriately
This ensures the flex height constraint propagates through every level
of the CodeMirror DOM tree, and only .cm-scroller scrolls.
Layout chain:
.cm-editor-container (flex-1, min-h-0)
└─ wrapper div (flex:1, min-h-0, overflow:hidden)
└─ .cm-editor (flex:1, min-h-0, overflow:hidden)
└─ .cm-scroller (min-h-0, overflow:auto) ← only this scrolls
react-ace v14 is CommonJS-only with no ESM entry point, making it
fundamentally incompatible with Vite's ESM-first dev server. Every
CJS interop workaround failed. Switched to @uiw/react-codemirror v4.25
which ships proper dual ESM+CJS and works with Vite out of the box.
Changes:
- Remove ace-builds and react-ace dependencies
- Add @uiw/react-codemirror + 16 @codemirror/lang-* packages
- Add @uiw/codemirror-theme-tomorrow-night-blue (closest to ACE's 'tomorrow')
- Add @replit/codemirror-lang-csharp for C# support
- Rewrite EditorPanel.tsx: delete 108 lines of ACE boilerplate
(?url imports, setModuleUrl, CJS interop hack), replace with
~30 lines of clean CodeMirror language extension setup
- Delete vite.d.ts (only needed for ACE ?url import types)
- Remove optimizeDeps.include from vite.config.ts (not needed for CM)
- Add CodeMirror flex layout CSS to index.css
Supported languages: JavaScript/JSX, TypeScript/TSX, Python, JSON,
HTML, CSS, Less, YAML, Markdown, SQL, Java, Go, Rust, C/C++, C#,
PHP, XML. Unsupported types fall back to plain text.
Verified: tsc clean, vite build passes, heartbeat worker intact.
react-ace v14 ships CommonJS only ('main': 'lib/index.js'). Vite's dev
server pre-bundling wraps CJS modules as namespace objects where the
default export is nested under .default. This caused 'Element type is
invalid: got object' because import Ace from 'react-ace' resolved to
the module namespace instead of the React component.
Fix: import * as ReactAceModule and extract default with fallback:
const Ace = ReactAceModule.default || ReactAceModule
Same treatment for ace-builds import. Production build (Rolldown) was
unaffected due to different CJS interop handling.
- Added react-ace and ace-builds to optimizeDeps.include
- This forces Vite to properly bundle the CommonJS react-ace module
- Resolves 'Element type is invalid' error when opening files
The react-ace package uses CommonJS exports, and Vite needs to
pre-bundle it to properly handle the default export in ESM context.
- Fixed Ace import (default import, not named)
- Moved EditorPanel from FilesPanel to ChatSessionView
- Editor now replaces chat view when file is selected (per UI design guide)
- FILES panel now contains only the file tree
- Added editorFilePath state to track open file
- File selection in tree opens editor in content area
- Close button returns to chat view
This matches the UI design guide specification where the File Editor
replaces the Chat View in the content area when a file is selected.
Root Cause: CSS flex items default to min-height: auto, which prevents
flex-1 elements from shrinking below their content size. This caused
the FilesPanel to grow beyond its allocated space when the file tree
had many entries, pushing content off-screen.
Changes:
- FilesPanel.tsx: Added min-h-0 to root div to override min-height: auto
This allows flex-1 to actually constrain height and enable scrolling
- FileTree.tsx: Removed redundant overflow-auto and h-full from root div
The parent (FilesPanel flex-1 overflow-auto) already handles scrolling.
Nested scroll containers create height resolution issues.
The sidebar layout is now a clean single-scroll-container hierarchy:
Sidebar (flex flex-col, no overflow)
↳ SESSION (shrink-0, natural height)
↳ PROJECT (shrink-0, natural height)
↳ FilesPanel (flex-1 min-h-0) — constrained to available space
↳ Header (natural height)
↳ Scroll area (flex-1 overflow-auto) — THE scroll container
↳ FileTree (p-2 only) — no overflow, no h-full
↳ Footer (natural height)
- SESSION and PROJECT panels now have shrink-0 to prevent them from
growing unbounded and pushing FILES panel off-screen
- FILES panel with flex-1 now properly fills remaining vertical space
- File tree scrolls in-place while SESSION/PROJECT stay fixed
- FileTree had flex-1 inside an overflow container which didn't work
- Changed to h-full to properly fill the parent container height
- Scrolling now works correctly in the file tree area
- The sidebar container had overflow-y-auto which caused the entire sidebar
to scroll when FILES panel content grew
- FILES panel already has proper flex-1 and internal overflow-auto handling
- Now only the file tree scrolls in place while SESSION and PROJECT panels
remain fixed as expected
- Fixes UX issue where entire sidebar would scroll vertically
- Add flex-1 to FilesPanel root div
- Sidebar is flex flex-col, FILES panel now grows to fill space
- SESSION and PROJECT panels remain natural height
- FILES panel expands into all remaining vertical space
This eliminates the gap below the FILES panel footer by making
the panel itself grow rather than just making the tree bigger.
- Remove max-h-80 constraint from FileTree
- FileTree uses flex-1 to expand and fill available space
- Panel now properly fills sidebar from top to bottom
- File tree scrolls internally when content overflows
The FILES panel header, file tree, and footer now form a proper
flex column that fills all remaining vertical space in the sidebar.
- Change FilesPanel overflow-hidden to overflow-auto for scrolling
- Add max-h-80 to FileTree to limit height while allowing scroll
- Add select-none to FileTreeNode to prevent text selection
- Cursor-pointer already present for clickable indication
Now the file tree scrolls independently within the FILES panel,
and text cannot be selected during rapid clicking.
- Replace recursive buildTree with buildVisibleNodes approach
- Build flat list of visible nodes based on expanded state
- Use processNode helper to traverse tree structure correctly
- Each node appears exactly once in the rendered output
- Eliminates duplication when expanding directories
- Change buildTree from .map() to for-loop to properly render children
- Append expanded directory children to nodes array immediately
- Fix TypeScript error by using ReactElement instead of JSX.Element
- Children now render correctly when directories are expanded
- Create comprehensive plan document for agent instructions text area
- Define requirements, acceptance criteria, and technical implementation
- Include UI/UX mockups and testing strategy
- Plan discovered during FILES panel implementation
- Addresses need for project-specific acceptance criteria
Add end-to-end abort support: AbortSignal in @gadget/ai providers,
abortWorkOrder socket message, drone AbortController handling,
Cancel button and double-Esc in frontend, and aborted turn status display.
The Home icon in the PROJECT panel now navigates to /projects/{slug}
instead of /projects/{id}. This opens Project Manager with the
project already selected and displayed.
Adds type definitions + forwarding for status, reconnect_attempt, reconnect_failed, reconnect events.
Frontend build now runs tsc --noEmit before vite build so undefined socket events cause failures.
Fixes pre-existing type errors exposed by strict mode in the frontend.
- Switch frontend sign-in to /api/v1/auth/sign-in endpoint (includes persona)
- Add updateUser() to App context for proper state management
- Fix Settings.tsx save flow to use updateUser() instead of broken localStorage merge
- Remove unused web AuthController (gadget-code/src/controllers/auth.ts)
- Fix UserApiControllerV1 to return flat user object instead of double-wrapped
- Remove SessionType enum and references (dead code)
- Add proper server sign-out call before clearing local state
Resolves issue where User Settings view didn't display persona text even though it existed in the database.
