New chat tool: chat_export
- Export current ChatSession and all finished ChatTurn records to disk
- Two formats: markdown (human-readable) and json (machine-readable)
- JSON exports always include a companion -readme.md with author credits,
Gadget Code version/link, AI provider/model/parameters
- Output to .gadget/exports/ with sanitized session name + timestamp
- Security-first: excludes emails, API keys, baseUrls, system prompts,
gitUrls, and other PII/infrastructure details from all exports
- Only finished/aborted/error turns included (processing excluded)
- Follows SubagentTool setter-injection pattern for session data
- Available in all chat session modes (plan/build/test/ship/dev)
Files:
- packages/ai-toolbox/src/chat/export.ts (NEW - 729 lines)
- packages/ai-toolbox/src/chat/index.ts (barrel update)
- gadget-drone/src/tools/index.ts (re-export update)
- gadget-drone/src/services/agent.ts (import, register, getExportData)
- auto-generate name test: mock drone to accept work order so success callback runs
- session lock test: make async, mock TabLock, use vi.waitFor for async callback chain
- Add detectWorkspace() utility in packages/api/src/lib/workspace-detector.ts
that walks up from process.cwd() looking for .gadget/workspace.json
- Update gadget-drone to detect workspace at startup, change to workspace
directory, and restore original startup directory on shutdown
- Update gadget-tasks with same workspace detection pattern
- Both tools now fail fast if started outside a managed workspace
- Prevents creating invalid workspaces when started from subdirectories
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.
- README.md: Added gadget-tasks and @gadget/ai-toolbox to projects table,
added Scheduled Tasks architecture section with diagram, updated
monorepo structure, added gadget-tasks to dev server instructions,
added doc link
- docs/agent-toolbox.md: Updated to reflect @gadget/ai-toolbox extraction
from @gadget/ai. Changed IAiEnvironment → GadgetToolboxEnvironment,
AiTool → GadgetTool, updated import paths, config examples, and added
Tool Categories section. Clarified gadget-tasks is NOT a consumer.
- docs/gadget-tasks.md: New documentation covering architecture, per-task
execution flow, configuration, startup/shutdown sequences, concurrency,
work order tracking, heartbeat, error recovery, and getting started.
Converts gadget-tasks from a duplicated codebase with direct MongoDB access
to a headless IDE client that uses gadget-code's REST API and Socket.IO
protocol to submit and process task prompts through the existing pipeline.
Deleted (no longer needed):
- gadget-tasks/src/models/ (5 Mongoose models — duplicated from gadget-code)
- gadget-tasks/data/prompts/ (11 prompt templates — duplicated from gadget-code)
- gadget-tasks/src/services/executor.ts (629-line AWL loop — duplicated from gadget-drone)
- gadget-tasks/src/services/ai.ts (direct AI API calls — drones do this now)
- gadget-tasks/src/services/workspace.ts (workspace management — drones do this now)
Added:
- gadget-tasks/src/services/platform.ts — REST API + Socket.IO headless IDE client
with session lock, workspace mode, prompt submission, work order tracking
Rewritten:
- gadget-tasks/src/gadget-tasks.ts — new startup: user login → auth → drone
selection → Socket.IO connect → schedule tasks (no MongoDB)
- gadget-tasks/src/services/scheduler.ts — delegates to PlatformService.executeTask()
- gadget-tasks/src/config/env.ts — platform.baseUrl config, no mongodb/google
gadget-code changes:
- Added PATCH /api/v1/projects/:projectId/tasks/:taskId/lastRun route
- Added ProjectService.updateTaskLastRun() for atomic task field update
Config changes:
- GadgetTasksConfig: replaced mongodb with platform.baseUrl, removed google.cse
- Dependencies: removed mongoose, @gadget/ai, @gadget/ai-toolbox, dayjs,
simple-git, nanoid; added socket.io-client, @inquirer/prompts
- 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
Complete Phase 1 of subprocess management in gadget-drone:
- SubProcessService with graceful shutdown (SIGINT→SIGKILL), halt, getLog
- SubprocessTool with create/list/kill/killAll/halt/log commands
- Registered in agent toolbox for build/test/ship/develop modes
- Fixed missing {{process_management_block}} replacement in chat-session.ts
- 34 unit tests across service and tool
- Comprehensive documentation in docs/subprocess.md
Documents:
- Complete session history and what was accomplished
- ACE → CodeMirror migration rationale and steps
- Flex layout height constraint fix pattern
- Key technical learnings (CJS/ESM interop, flex layouts)
- Remaining steps organized by priority (high/medium/low)
- Continuation prompt template for next session
- MVP success criteria (all ✅ complete)
This serves as the handoff document for the next developer
or AI agent continuing work on User Mode.
Documents the complete ACE → CodeMirror migration, including:
- Root cause analysis of react-ace CJS/ESM incompatibility with Vite
- Migration steps and rationale for @uiw/react-codemirror
- Flex layout height constraint fix and the underlying pattern
- Key technical learnings about CJS/ESM interop and flex layouts
- Remaining steps and continuation prompt for next session
This serves as the authoritative reference for why we use CodeMirror
and how to properly constrain third-party components in flex layouts.
