## role
Design and specification package for implementing multi-session terminal UX support in a web-based tool instance platform.
## files
- .openspec.yaml | Defines an open specification for a multi-session terminal user experience project
- apply-pr1.md | Documents the implementation of database schema, Alembic migration, and TerminalManager multi-session core for a multi-session terminal UX feature. | dep: Alembic, SQLAlchemy, aiosqlite, asyncio, pytest, TerminalSession, TerminalManager, UUIDPrimaryKeyMixin, TimestampMixin, SessionLocal
- apply-pr2.md | Empty file with no functionality
- apply-pr3.md | Documents a pull request implementing a frontend multi-session terminal UI with tabbed management, fullscreen mode, keyboard shortcuts, and mobile support. | dep: React, TypeScript, WebSocket, CSS, Python (backend terminal manager), testing framework
- design.md | Software design document specifying architecture and implementation for adding multi-session terminal support (up to 5 concurrent sessions) to an existing tool instance platform | dep: FastAPI, SQLAlchemy, Alembic, React, xterm.js, WebSocket, PTY, docker exec, Python, TypeScript
- explore.md | Explores architectural options for adding multi-session terminal support to an existing persistent terminal system, evaluating backend, frontend, protocol, and database design choices with recommendations for MVP implementation. | dep: TerminalManager, TerminalSession, TerminalComponent, TerminalPage, MobileTerminalWrapper, xterm.js, FastAPI, SQLAlchemy, alembic
- proposal.md | Proposes architectural changes to support multiple concurrent terminal sessions per tool instance with improved UI/UX features | dep: TerminalManager, TerminalSession, api/terminal.py, TerminalComponent, terminal.tsx, WebSocket protocol, database schema
- tasks.md | A software design document detailing a 12-task implementation plan for adding multi-session terminal UX support to a web application, organized across 3 stacked pull requests with TDD acceptance criteria. | dep: Alembic, SQLAlchemy, FastAPI, WebSocket, React, TypeScript, xterm.js, PTY, UUID, pytest, Jest/RTL
## arch
Document-driven architecture using stacked PR planning (3 PRs: backend/core, empty/placeholder, frontend/UI), TDD acceptance criteria, and explicit MVP scoping with 5-session concurrency limit.
