Building from source

The application lives in app/. Runtime is Bun. The TUI is OpenTUI.

export PATH="$HOME/.bun/bin:$PATH"
cd app
bun install
bun run src/bin.ts --help
bun test
bun run check:coverage
bun run typecheck
bun run typecheck:web
bun run check:architecture
bun run check:dead
bun run check:dup

From the repository root (after bun install in app/):

bun run app/src/bin.ts
cd app && bun link    # optional: `devctl` on PATH

Layout

Path	Role
app/src/bin.ts	Entry
app/src/bootstrap/	Composition roots (daemon + client)
app/src/application/client-runtime.ts	Injected CLI/TUI operations and controller contract

app/src/presentation/tui/	OpenTUI screens and overlays
app/src/presentation/tui/hooks/	Client queries, command execution, and TUI state
app/src/presentation/tui/helpers/	Screen-specific formatting, navigation, logs, and plan helpers
app/src/presentation/mcp/	Streamable HTTP MCP server
app/src/presentation/web/	Loopback telemetry web UI (SPA is authored in app/web/ and embedded here)
app/src/domain/	Service, identity, config, log, session, and preference types and policies
app/src/adapters/config/	Discover, decode, merge, validate
app/src/adapters/process/	Host process runtime
app/src/adapters/google/	Google / IAP / tokens
app/src/adapters/daemon/supervisor.ts	Daemon host (socket, recovery, watch, listeners)
app/src/adapters/rpc/controller.ts	Local supervisor or socket / named-pipe client
app/tui.json	Starter TUI preferences

Layer rules: architecture.md. Check with bun run check:architecture. Coverage: bun run check:coverage (aggregate funcs/lines; OpenTUI screens and hooks are ignored). Unused files and dependencies: bun run check:dead (Knip). Copy-paste clones: bun run check:dup (jscpd).

There is no separate Go tree.

TUI preferences

Configuration is tui.json or tui.jsonc: theme, keybinds, leader_timeout, font_size, mouse, scroll_speed, log_timestamps, log_metadata, web_appearance, mcp_enabled, mcp_port, mcp_disabled_tools, mcp_enabled_tools, regenerate_session_tokens, dismissed_notifications.

mcp_disabled_tools is a deny-list of MCP tool names that are on by default. mcp_enabled_tools opts in tools that are off by default (exec_service). See MCP. regenerate_session_tokens (default false) remints the saved MCP and web bearer tokens after 7 days. /notify dismiss appends this version to dismissed_notifications so the update banner does not return.

Search order (later sources win). DEVCTL_TUI_CONFIG / OPENCODE_TUI_CONFIG is exclusive and session-only for writes:

Settings default to this repository. Theme, mouse, leader, scroll, log columns, web appearance, and token regeneration follow the Save to toggle. MCP listen / port / tool lists always write the repo overlay. dismissed_notifications stay user-global. DEVCTL_TUI_CONFIG still wins as the only file when set.

keybinds merge with the built-in defaults, so you only override what you change. Defaults use cmd on macOS and ctrl on Linux/Windows (command+c / ctrl+c in the TUI).

{
  "theme": "devctl",
  "leader_timeout": 2000,
  "keybinds": {
    "leader": "ctrl+x",
    "command_list": "ctrl+p"
  },
  "mouse": true,
  "mcp_enabled": false,
  "mcp_disabled_tools": [],
  "mcp_enabled_tools": [],
  "regenerate_session_tokens": false
}

Tests

cd app && bun test

Integration tests that need Google stay skipped unless credentials are present.
