clide forwards composer input to a headless (stream-json) CLI, where the
TUI's interactive commands don't exist. A known-but-TUI-only command
errored raw ("/x isn't available in this environment", rendered as fake
claude prose); an un-advertised one (e.g. /effort on 2.1.175) was worse —
bracket-pasted to the model as literal text, burning a real turn.
Probed claude 2.1.175 for ground truth: the initialize handshake's
slash_commands advertises skills + the headless builtins only; forwarded
local-command output comes back as an assistant message with model
"<synthetic>"; set_effort is not a control subtype; /usage works headless.
- slash_commands.dart: SlashRoute routing table (owned > advertised >
TUI-only catalog > forward) + kTuiOnlyCommands with clide-native hints
+ tuiOnlyNotice(). One source of truth replacing ad-hoc checks.
- claude_pane._send routes 'unavailable' to a local notice card; nothing
reaches the session.
- transcript_reader: AssistantTextMessage.synthetic ("<synthetic>" model)
so CLI-local output is distinguishable; "<synthetic>" no longer
clobbers the tracked model in SessionStatus (latent /usage bug).
- conversation_view: synthetic output renders as a muted framed "clide"
card (T-306 styling), never coral Claude prose.
- kFallbackSlashCommands trimmed to the genuinely-headless builtin set —
it doubles as the router's advertised fallback, and the old list's
TUI-only entries would have routed to a raw CLI error.
Board (rides this commit): T-414 gains the user's sidebar styling-pass
note; T-416 filed — surface Claude Code Workflow runs in convo/status.

clide
An IDE for Claude Code CLI. Native rendering, terminal-first interaction, pql-powered queries, canvas and graph surfaces. Linux and macOS.
Architecture
Single Flutter package at the repo root. The app hosts everything in-process: IPC server, subsystem handlers (pane, files, editor, git, pql), and the extension framework. tmux owns Claude session persistence (D-41).
lib/— all Dart code. Core subsystems (lib/src/), kernel services (lib/kernel/), UI widgets (lib/widgets/), built-in extensions (lib/builtin/), the extension framework (lib/extension/).- PTY —
lib/src/pty/spawns child processes via Dart FFIposix_openpt()+posix_spawn()directly; no external helper binary. native/— vendored native libraries (libtree-sitter.sowith wasmtime embedded). Linux only today.- pql — external supporter tool. Clide wraps it for every query surface; never re-implements it.
Claude drives the UI through a clide CLI surface (Bash, not MCP). Every CLI subcommand has a UI affordance and every UI action has a CLI equivalent (D-6).
Built-in extensions
canvas, claude, claude_control, decisions, diff, editor, extensions_ui, files, git, graph, grammars_core, ipc_status, keybindings_ui, markdown, pql, problems, settings_ui, terminal, theme_picker, tickets, todos, welcome.
Building
Requires Flutter (stable channel) and pql
on the host. pql is a hard dependency — the pre-push gate runs pql decisions validate and the governance + ticket workflow is built on it (see its repo for
install). One-time setup:
make hooks && flutter pub get
pql init # once, in the repo root — wires up the pql skill + perms
Then:
make run # launch the desktop app
make test # fast suite: analyze + format + unit + widget + golden
make test-core # core subsystem tests (IPC, PTY, git, pane registry)
make test-a11y # accessibility contract tests
make test-integration # real app boot integration tests
make build-linux # flutter build linux
make build-macos # flutter build macos
make push-check # pre-push gate: decisions + core + fast + a11y + coverage + changelog
Status
Pre-v2.0 (2.0.0-dev). Interaction model and panel system landed. The Python Textual v1.2.0 predecessor is archived under legacy/.
