Glossary
Terms used in TrueDeck docs and UI.
Agent
A coding CLI preset (Grok, Codex, Cursor Agent, Claude, …) or a plain shell. Spawned as a PTY session, not an in-process model SDK.
Agent frame / frame TUI
In-terminal chrome (truedeck-frame.mjs) that reserves a header band above the child agent TUI. Controlled by agentFrameTui / frameShellPanes. See Agent frame.
AptInt
Not used in TrueDeck. AptInt is an arbitrary-precision integer type from other projects (e.g. SPTS Roblox stats). TrueDeck does not implement AptInt.
Auto-context
Generated markdown at .truedeck/auto-context.md summarizing project memory pointers for agents. Refreshed on project open / agent spawn.
Backend (Rust)
Primary truedeck-backend process owning PTY and related RPC. See RUST-BACKEND.md.
Tasks / launch
Task records + MCP launch (truedeck_launch) that dispatch to real agent PTYs. No board UI - see Task board and MCP.
Command session
A PTY started from an on-open or ad-hoc shell command (kind: 'command'), not a named agent preset. Framed only if frameShellPanes is on.
Dispatch
Spawning an agent for a board task: write task file, set env, create run, seed prompt. Implemented in task-dispatch.ts.
Group (pane group)
A leaf in the pane tree: its own tab bar and active tab. Multiple groups appear side-by-side or stacked after a split.
Hub (MCP hub)
Unified MCP configuration managed by TrueDeck and synced to agent clients. Built-in server id truedeck-hub. See MCP.
Agent bus
File-backed mailbox plus live PTY inject so TrueDeck agents can message other terminals (and other PCs running TrueDeck with global memory synced). Tools: truedeck_peers, truedeck_send, truedeck_inbox. See Agent bus.
Leaf
A pane-tree node that holds tab indices and an active tab (not a split).
Memory / TrueMemory
Markdown notes under .memory/ (repo) and the global memory directory. Always available offline. Distinct from MemPalace graph storage.
MemPalace / palace
Native memory backend (graph/vector palace) when enabled. Path often ~/.mempalace/palace or Settings palacePath. See memory-providers.md.
On-open command
Shell command associated with a project that can spawn when the project opens (e.g. rojo serve).
Pane
A rectangular terminal region (leaf group). Splits create more panes up to 16.
Project
A tracked folder (ProjectConfig) with root path, recents, on-open commands, and default agents.
PTY
Pseudo-terminal hosting an agent or shell. Engines: node-pty or Rust sidecars.
Resolve / resolve-command
Mapping agent id + command name to an on-disk executable, with IDE blocking for Cursor. See Agents.
Run
A recorded agent execution linked to a task (AgentRun: start/end times, exit code, session id).
Session
A live (or exited) PTY instance tracked as SessionInfo with agent metadata and project root.
Session layout
Persisted snapshot of tabs + pane tree (session-layout.json) used for restore.
Split
A pane-tree node with direction (row / column), ratio, and two children. Created via Ctrl+D (vertical) / Ctrl+X (horizontal) or drag-drop.
Studio UI
Electron + React + xterm interface (npm start). Contrasts with the Blessed TUI (npm run tui).
Task
Kanban card (Task) with status, assignee agent, and session/run links when present.
TUI
- TrueDeck’s terminal-only app mode
- Any agent’s full-screen terminal UI (Codex, Claude Code, …)
Wing
MemPalace naming concept: a project-scoped area inside the palace (TRUEDECK_MEMORY_WING).
xterm
The browser terminal emulator in the renderer (xterm + Fit / WebLinks addons) attached to PTY data over IPC.
