From 006dbe19f18828ca4c3cfe03b60237adc0ee7409 Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Sat, 25 Apr 2026 21:03:04 -0700 Subject: [PATCH] =?UTF-8?q?feat(extension):=20Terminal-only=20sidebar=20?= =?UTF-8?q?=E2=80=94=20auth=20fix,=20UX=20polish,=20chat=20rip?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The chat queue path is gone. The Chrome side panel is now just an interactive claude PTY in xterm.js. Activity / Refs / Inspector still exist behind the `debug` toggle in the footer. Three threads of change, all from dogfood iteration on top of cc-pty-import: 1. fix(server): cross-port WS auth via Sec-WebSocket-Protocol - Browsers can't set Authorization on a WebSocket upgrade. We had been minting an HttpOnly gstack_pty cookie via /pty-session, but SameSite=Strict cookies don't survive the cross-port jump from server.ts:34567 to the agent's random port from a chrome-extension origin. The WS opened then immediately closed → "Session ended." - /pty-session now also returns ptySessionToken in the JSON body. - Extension calls `new WebSocket(url, [`gstack-pty.`])`. Browser sends Sec-WebSocket-Protocol on the upgrade. - Agent reads the protocol header, validates against validTokens, and MUST echo the protocol back (Chromium closes the connection immediately if a server doesn't pick one of the offered protocols). - Cookie path is kept as a fallback for non-browser callers (curl, integration tests). - New integration test exercises the full protocol-auth round-trip via raw fetch+Upgrade so a future regression of this exact class fails in CI. 2. fix(extension): UX polish on the Terminal pane - Eager auto-connect when the sidebar opens — no "Press any key to start" friction every reload. - Always-visible ↻ Restart button in the terminal toolbar (not gated on the ENDED state) so the user can force a fresh claude mid-session. - MutationObserver on #tab-terminal's class attribute drives a fitAddon.fit() + term.refresh() when the pane becomes visible again — xterm doesn't auto-redraw after display:none → display:flex. 3. feat(extension): rip the chat tab + sidebar-agent.ts - Sidebar is Terminal-only. No more Terminal | Chat primary nav. - sidebar-agent.ts deleted. /sidebar-command, /sidebar-chat, /sidebar-agent/event, /sidebar-tabs* and friends all deleted. - The pickSidebarModel router (sonnet vs opus) is gone — the live PTY uses whatever model the user's `claude` CLI is configured with. - Quick-actions (🧹 Cleanup / 📸 Screenshot / 🍪 Cookies) survive in the Terminal toolbar. Cleanup now injects its prompt into the live PTY via window.gstackInjectToTerminal — no more /sidebar-command POST. The Inspector "Send to Code" action uses the same injection path. - clear-chat button removed from the footer. - sidepanel.js shed ~900 lines of chat polling, optimistic UI, stop-agent, etc. Net diff: -3.4k lines across 16 files. CLAUDE.md, TODOS.md, and docs/designs/SIDEBAR_MESSAGE_FLOW.md rewritten to match. The sidebar regression test (browse/test/sidebar-tabs.test.ts) is rewritten as 27 structural assertions locking the new layout — Terminal sole pane, no chat input, quick-actions in toolbar, eager-connect, MutationObserver repaint, restart helper. --- CLAUDE.md | 45 +- TODOS.md | 22 - browse/src/cli.ts | 61 +- browse/src/server.ts | 958 +-------------- browse/src/sidebar-agent.ts | 947 --------------- browse/src/terminal-agent.ts | 60 +- browse/test/sidebar-agent-roundtrip.test.ts | 226 ---- browse/test/sidebar-agent.test.ts | 562 --------- browse/test/sidebar-tabs.test.ts | 285 +++-- .../test/terminal-agent-integration.test.ts | 61 +- browse/test/terminal-agent.test.ts | 27 +- docs/designs/SIDEBAR_MESSAGE_FLOW.md | 379 ++---- extension/sidepanel-terminal.js | 175 ++- extension/sidepanel.css | 54 +- extension/sidepanel.html | 95 +- extension/sidepanel.js | 1043 +---------------- 16 files changed, 771 insertions(+), 4229 deletions(-) delete mode 100644 browse/src/sidebar-agent.ts delete mode 100644 browse/test/sidebar-agent-roundtrip.test.ts delete mode 100644 browse/test/sidebar-agent.test.ts diff --git a/CLAUDE.md b/CLAUDE.md index 8699d49a..06f18434 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -225,24 +225,35 @@ When you need to interact with a browser (QA, dogfooding, cookie setup), use the project uses. **Sidebar architecture:** Before modifying `sidepanel.js`, `background.js`, -`content.js`, `sidebar-agent.ts`, `terminal-agent.ts`, or sidebar-related -server endpoints, read `docs/designs/SIDEBAR_MESSAGE_FLOW.md`.
