CLI commands: inspect (CDP cascade), style (live CSS mod), cleanup (page clutter removal), prettyscreenshot (clean screenshot pipeline). * feat: sidebar CSS inspector — element picker, box model, rule cascade, quick edit Extension changes for the visual CSS inspector: - inspector.js: element picker with hover highlight, CSS selector generation, basic mode fallback (getComputedStyle + CSSOM), page alteration handlers - inspector.css: picker overlay styles (blue highlight + tooltip) - background.js: inspector message routing (picker <-> server <-> sidepanel) - sidepanel: Inspector tab with box model viz (gstack palette), matched rules with specificity badges, computed styles, click-to-edit quick edit, Send to Agent/Code button, empty/loading/error states * docs: document inspect, style, cleanup, prettyscreenshot browse commands * feat: auto-track user-created tabs and handle tab close browser-manager.ts changes: - context.on('page') listener: automatically tracks tabs opened by the user (Cmd+T, right-click open in new tab, window.open). Previously only programmatic newTab() was tracked, so user tabs were invisible. - page.on('close') handler in wirePageEvents: removes closed tabs from the pages map and switches activeTabId to the last remaining tab. - syncActiveTabByUrl: match Chrome extension's active tab URL to the correct Playwright page for accurate tab identity. * feat: per-tab agent isolation via BROWSE_TAB environment variable Prevents parallel sidebar agents from interfering with each other's tab context. Three-layer fix: - sidebar-agent.ts: passes BROWSE_TAB= env var to each claude process, per-tab processing set allows concurrent agents across tabs - cli.ts: reads process.env.BROWSE_TAB and includes tabId in command request body - server.ts: handleCommand() temporarily switches activeTabId when tabId is present, restores after command completes (safe: Bun event loop is single-threaded) Also: per-tab agent state (TabAgentState map), per-tab message queuing, per-tab chat buffers, verbose streaming narration, stop button endpoint. * feat: sidebar per-tab chat context, tab bar sync, stop button, UX polish Extension changes: - sidepanel.js: per-tab chat history (tabChatHistories map), switchChatTab() swaps entire chat view, browserTabActivated handler for instant tab sync, stop button wired to /sidebar-agent/stop, pollTabs renders tab bar - sidepanel.html: updated banner text ("Browser co-pilot"), stop button markup, input placeholder "Ask about this page..." - sidepanel.css: tab bar styles, stop button styles, loading state fixes - background.js: chrome.tabs.onActivated sends browserTabActivated to sidepanel with tab URL for instant tab switch detection * test: per-tab isolation, BROWSE_TAB pinning, tab tracking, sidebar UX sidebar-agent.test.ts (new tests): - BROWSE_TAB env var passed to claude process - CLI reads BROWSE_TAB and sends tabId in body - handleCommand accepts tabId, saves/restores activeTabId - Tab pinning only activates when tabId provided - Per-tab agent state, queue, concurrency - processingTabs set for parallel agents sidebar-ux.test.ts (new tests): - context.on('page') tracks user-created tabs - page.on('close') removes tabs from pages map - Tab isolation uses BROWSE_TAB not system prompt hack - Per-tab chat context in sidepanel - Tab bar rendering, stop button, banner text * fix: resolve merge conflicts — keep security defenses + per-tab isolation Merged main's security improvements (XML escaping, prompt injection defense, allowed commands whitelist, --model opus, Write tool, stderr capture) with our branch's per-tab isolation (BROWSE_TAB env var, processingTabs set, no --resume). Updated test expectations for expanded system prompt. * chore: bump version and changelog (v0.13.9.0) * fix: add inspector message types to background.js allowlist Pre-existing bug found by Codex: ALLOWED_TYPES in background.js was missing all inspector message types (startInspector, stopInspector, elementPicked, pickerCancelled, applyStyle, toggleClass, injectCSS, resetAll, inspectResult). Messages were silently rejected, making the inspector broken on ALL pages. Also: separate executeScript and insertCSS into individual try blocks in injectInspector(), store inspectorMode for routing, and add content.js fallback when script injection fails (CSP, chrome:// pages). * feat: basic element picker in content.js for CSP-restricted pages When inspector.js can't be injected (CSP, chrome:// pages), content.js provides a basic picker using getComputedStyle + CSSOM: - startBasicPicker/stopBasicPicker message handlers - captureBasicData() with ~30 key CSS properties, box model, matched rules - Hover highlight with outline save/restore (never leaves artifacts) - Click uses e.target directly (no re-querying by selector) - Sends inspectResult with mode:'basic' for sidebar rendering - Escape key cancels picker and restores outlines * feat: cleanup + screenshot buttons in sidebar inspector toolbar Two action buttons in the inspector toolbar: - Cleanup (🧹): POSTs cleanup --all to server, shows spinner, chat notification on success, resets inspector state (element may be removed) - Screenshot (📸): POSTs screenshot to server, shows spinner, chat notification with saved file path Shared infrastructure: - .inspector-action-btn CSS with loading spinner via ::after pseudo-element - chat-notification type in addChatEntry() for system messages - package.json version bump to 0.13.9.0 * test: inspector allowlist, CSP fallback, cleanup/screenshot buttons 16 new tests in sidebar-ux.test.ts: - Inspector message allowlist includes all inspector types - content.js basic picker (startBasicPicker, captureBasicData, CSSOM, outline save/restore, inspectResult with mode basic, Escape cleanup) - background.js CSP fallback (separate try blocks, inspectorMode, fallback) - Cleanup button (POST /command, inspector reset after success) - Screenshot button (POST /command, notification rendering) - Chat notification type and CSS styles * docs: update project documentation for v0.13.9.0 * feat: cleanup + screenshot buttons in chat toolbar (not just inspector) Quick actions toolbar (🧹 Cleanup, 📸 Screenshot) now appears above the chat input, always visible. Both inspector and chat buttons share runCleanup() and runScreenshot() helper functions. Clicking either set shows loading state on both simultaneously. * test: chat toolbar buttons, shared helpers, quick-action-btn styles Tests that chat toolbar exists (chat-cleanup-btn, chat-screenshot-btn, quick-actions container), CSS styles (.quick-action-btn, .quick-action-btn.loading), shared runCleanup/runScreenshot helper functions, and cleanup inspector reset. * feat: aggressive cleanup heuristics — overlays, scroll unlock, blur removal Massively expanded CLEANUP_SELECTORS with patterns from uBlock Origin and Readability.js research: - ads: 30+ selectors (Google, Amazon, Outbrain, Taboola, Criteo, etc.) - cookies: OneTrust, Cookiebot, TrustArc, Quantcast + generic patterns - overlays (NEW): paywalls, newsletter popups, interstitials, push prompts, app download banners, survey modals - social: follow prompts, share tools - Cleanup now defaults to --all when no args (sidebar button fix) - Uses !important on all display:none (overrides inline styles) - Unlocks body/html scroll (overflow:hidden from modal lockout) - Removes blur/filter effects (paywall content blur) - Removes max-height truncation (article teaser truncation) - Collapses empty ad placeholder whitespace (empty divs after ad removal) - Skips gstack-ctrl indicator in sticky removal * fix: disable action buttons when disconnected, no error spam - setActionButtonsEnabled() toggles .disabled class on all cleanup/screenshot buttons (both chat toolbar and inspector toolbar) - Called with false in updateConnection when server URL is null - Called with true when connection established - runCleanup/runScreenshot silently return when disconnected instead of showing 'Not connected' error notifications - CSS .disabled style: pointer-events:none, opacity:0.3, cursor:not-allowed * test: cleanup heuristics, button disabled state, overlay selectors 17 new tests: - cleanup defaults to --all on empty args - CLEANUP_SELECTORS overlays category (paywall, newsletter, interstitial) - Major ad networks in selectors (doubleclick, taboola, criteo, etc.) - Major consent frameworks (OneTrust, Cookiebot, TrustArc, Quantcast) - !important override for inline styles - Scroll unlock (body overflow:hidden) - Blur removal (paywall content blur) - Article truncation removal (max-height) - Empty placeholder collapse - gstack-ctrl indicator skip in sticky cleanup - setActionButtonsEnabled function - Buttons disabled when disconnected - No error spam from cleanup/screenshot when disconnected - CSS disabled styles for action buttons * feat: LLM-based page cleanup — agent analyzes page semantically Instead of brittle CSS selectors, the cleanup button now sends a prompt to the sidebar agent (which IS an LLM). The agent: 1. Runs deterministic $B cleanup --all as a quick first pass 2. Takes a snapshot to see what's left 3. Analyzes the page semantically to identify remaining clutter 4. Removes elements intelligently, preserving site branding This means cleanup works correctly on any site without site-specific selectors. The LLM understands that "Your Daily Puzzles" is clutter, "ADVERTISEMENT" is junk, but the SF Chronicle masthead should stay. * feat: aggressive cleanup heuristics + preserve top nav bar Deterministic cleanup improvements (used as first pass before LLM analysis): - New 'clutter' category: audio players, podcast widgets, sidebar puzzles/games, recirculation widgets (taboola, outbrain, nativo), cross-promotion banners - Text-content detection: removes "ADVERTISEMENT", "Article continues below", "Sponsored", "Paid content" labels and their parent wrappers - Sticky fix: preserves the topmost full-width element near viewport top (site nav bar) instead of hiding all sticky/fixed elements. Sorts by vertical position, preserves the first one that spans >80% viewport width. Tests: clutter category, ad label removal, nav bar preservation logic. * test: LLM-based cleanup architecture, deterministic heuristics, sticky nav 22 new tests covering: - Cleanup button uses /sidebar-command (agent) not /command (deterministic) - Cleanup prompt includes deterministic first pass + agent snapshot analysis - Cleanup prompt lists specific clutter categories for agent guidance - Cleanup prompt preserves site identity (masthead, headline, body, byline) - Cleanup prompt instructs scroll unlock and $B eval removal - Loading state management (async agent, setTimeout) - Deterministic clutter: audio/podcast, games/puzzles, recirculation - Ad label text patterns (ADVERTISEMENT, Sponsored, Article continues) - Ad label parent wrapper hiding for small containers - Sticky nav preservation (sort by position, first full-width near top) * fix: prevent repeat chat message rendering on reconnect/replay Root cause: server persists chat to disk (chat.jsonl) and replays on restart. Client had no dedup, so every reconnect re-rendered the entire history. Messages from an old HN session would repeat endlessly on the SF Chronicle tab. Fix: renderedEntryIds Set tracks which entry IDs have been rendered. addChatEntry skips entries already in the set. Entries without an id (local notifications) bypass the check. Clear chat resets the set. * fix: agent stops when done, no focus stealing, opus for prompt injection safety Three fixes for sidebar agent UX: - System prompt: "Be CONCISE. STOP as soon as the task is done. Do NOT keep exploring or doing bonus work." Prevents agent from endlessly taking screenshots and highlighting elements after answering the question. - switchTab(id, opts): new bringToFront option. Internal tab pinning (BROWSE_TAB) uses bringToFront: false so agent commands never steal window focus from the user's active app. - Keep opus model (not sonnet) for prompt injection resistance on untrusted web pages. Remove Write from allowedTools (agent only needs Bash for $B). * test: agent conciseness, focus stealing, opus model, switchTab opts Tests for the three UX fixes: - System prompt contains STOP/CONCISE/Do NOT keep exploring - sidebar agent uses opus (not sonnet) for prompt injection resistance - switchTab has bringToFront option, defaults to true (opt-out) - handleCommand tab pinning uses bringToFront: false (no focus steal) - Updated stale tests: switchTab signature, allowedTools excludes Write, narration -> conciseness, tab pinning restore calls * test: sidebar CSS interaction E2E — HN comment highlight round-trip New E2E test (periodic tier, ~$2/run) that exercises the full sidebar agent pipeline with CSS interaction: 1. Agent navigates to Hacker News 2. Clicks into the top story's comments 3. Reads comments and identifies the most insightful one 4. Highlights it with a 4px solid orange outline via style injection Tests: navigation, snapshot, text reading, LLM judgment, CSS modification. Requires real browser + real Claude (ANTHROPIC_API_KEY). * fix: sidebar CSS E2E test — correct idle timeout (ms not s), pipe stdio Root cause of test failure: BROWSE_IDLE_TIMEOUT is in milliseconds, not seconds. '600' = 0.6 seconds, server died immediately after health check. Fixed to '600000' (10 minutes). Also: use 'pipe' stdio instead of file descriptors (closing fds kills child on macOS/bun), catch ConnectionRefused on poll retry, 4 min poll timeout for the multi-step opus task. Test passes: agent navigates to HN, reads comments, identifies most insightful one, highlights it with orange CSS, stops. 114s, $0.00. --------- Co-authored-by: Claude Opus 4.6 (1M context) --- BROWSER.md | 3 +- CHANGELOG.md | 30 + CLAUDE.md | 2 +- README.md | 2 +- SKILL.md | 4 + VERSION | 2 +- browse/SKILL.md | 28 + browse/SKILL.md.tmpl | 24 + browse/src/browser-manager.ts | 81 +- browse/src/cdp-inspector.ts | 761 ++++++++++++++++ browse/src/cli.ts | 4 +- browse/src/commands.ts | 7 + browse/src/read-commands.ts | 49 ++ browse/src/server.ts | 413 +++++++-- browse/src/sidebar-agent.ts | 157 +++- browse/src/write-commands.ts | 486 +++++++++++ browse/test/sidebar-agent.test.ts | 353 ++++++++ browse/test/sidebar-security.test.ts | 2 +- browse/test/sidebar-ux.test.ts | 1194 ++++++++++++++++++++++++++ extension/background.js | 169 +++- extension/content.js | 209 +++++ extension/inspector.css | 29 + extension/inspector.js | 459 ++++++++++ extension/manifest.json | 2 +- extension/sidepanel.css | 704 ++++++++++++++- extension/sidepanel.html | 95 +- extension/sidepanel.js | 838 +++++++++++++++++- package.json | 2 +- test/helpers/touchfiles.ts | 2 + test/skill-e2e-sidebar.test.ts | 190 ++++ test/skill-validation.test.ts | 5 +- 31 files changed, 6176 insertions(+), 130 deletions(-) create mode 100644 browse/src/cdp-inspector.ts create mode 100644 browse/test/sidebar-ux.test.ts create mode 100644 extension/inspector.css create mode 100644 extension/inspector.js diff --git a/BROWSER.md b/BROWSER.md index 8e82a6387..cb90aa44e 100644 --- a/BROWSER.md +++ b/BROWSER.md @@ -10,7 +10,8 @@ This document covers the command reference and internals of gstack's headless br | Read | `text`, `html`, `links`, `forms`, `accessibility` | Extract content | | Snapshot | `snapshot [-i] [-c] [-d N] [-s sel] [-D] [-a] [-o] [-C]` | Get refs, diff, annotate | | Interact | `click`, `fill`, `select`, `hover`, `type`, `press`, `scroll`, `wait`, `viewport`, `upload` | Use the page | -| Inspect | `js`, `eval`, `css`, `attrs`, `is`, `console`, `network`, `dialog`, `cookies`, `storage`, `perf` | Debug and verify | +| Inspect | `js`, `eval`, `css`, `attrs`, `is`, `console`, `network`, `dialog`, `cookies`, `storage`, `perf`, `inspect [selector] [--all]` | Debug and verify | +| Style | `style `, `style --undo [N]`, `cleanup [--all]`, `prettyscreenshot` | Live CSS editing and page cleanup | | Visual | `screenshot [--viewport] [--clip x,y,w,h] [sel\|@ref] [path]`, `pdf`, `responsive` | See what Claude sees | | Compare | `diff ` | Spot differences between environments | | Dialogs | `dialog-accept [text]`, `dialog-dismiss` | Control alert/confirm/prompt handling | diff --git a/CHANGELOG.md b/CHANGELOG.md index a035a5ec8..cfa6a53d4 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -1,5 +1,35 @@ # Changelog +## [0.14.2.0] - 2026-03-30 — Sidebar CSS Inspector + Per-Tab Agents + +The sidebar is now a visual design tool. Pick any element on the page and see the full CSS rule cascade, box model, and computed styles right in the Side Panel. Edit styles live and see changes instantly. Each browser tab gets its own independent agent, so you can work on multiple pages simultaneously without cross-talk. Cleanup is LLM-powered... the agent snapshots the page, understands it semantically, and removes the junk while keeping the site's identity. + +### Added + +- **CSS Inspector in the sidebar.** Click "Pick Element", hover over anything, click it, and the sidebar shows the full CSS rule cascade with specificity badges, source file:line, box model visualization (gstack palette colors), and computed styles. Like Chrome DevTools, but inside the sidebar. +- **Live style editing.** `$B style .selector property value` modifies CSS rules in real time via CDP. Changes show instantly on the page. Undo with `$B style --undo`. +- **Per-tab agents.** Each browser tab gets its own Claude agent process via `BROWSE_TAB` env var. Switch tabs in the browser and the sidebar swaps to that tab's chat history. Ask questions about different pages in parallel without agents fighting over which tab is active. +- **Tab tracking.** User-created tabs (Cmd+T, right-click "Open in new tab") are automatically tracked via `context.on('page')`. The sidebar tab bar updates in real time. Click a tab in the sidebar to switch the browser. Close a tab and it disappears. +- **LLM-powered page cleanup.** The cleanup button sends a prompt to the sidebar agent (which IS an LLM). The agent runs a deterministic first pass, snapshots the page, analyzes what's left, and removes clutter intelligently while preserving site branding. Works on any site without brittle CSS selectors. +- **Pretty screenshots.** `$B prettyscreenshot --cleanup --scroll-to ".pricing" ~/Desktop/hero.png` combines cleanup, scroll positioning, and screenshot in one command. +- **Stop button.** A red stop button appears in the sidebar when an agent is working. Click it to cancel the current task. +- **CSP fallback for inspector.** Sites with strict Content Security Policy (like SF Chronicle) now get a basic picker via the always-loaded content script. You see computed styles, box model, and same-origin CSS rules. Full CDP mode on sites that allow it. +- **Cleanup + Screenshot buttons in chat toolbar.** Not hidden in debug... right there in the chat. Disabled when disconnected so you don't get error spam. + +### Fixed + +- **Inspector message allowlist.** The background.js allowlist was missing all inspector message types, silently rejecting them. The inspector was broken for all pages, not just CSP-restricted ones. (Found by Codex review.) +- **Sticky nav preservation.** Cleanup no longer removes the site's top nav bar. Sorts sticky elements by position and preserves the first full-width element near the top. +- **Agent won't stop.** System prompt now tells the agent to be concise and stop when done. No more endless screenshot-and-highlight loops. +- **Focus stealing.** Agent commands no longer pull Chrome to the foreground. Internal tab pinning uses `bringToFront: false`. +- **Chat message dedup.** Old messages from previous sessions no longer repeat on reconnect. + +### Changed + +- **Sidebar banner** now says "Browser co-pilot" instead of the old mode-specific text. +- **Input placeholder** is "Ask about this page..." (more inviting than the old placeholder). +- **System prompt** includes prompt injection defense and allowed-commands whitelist from the security audit. + ## [0.14.1.0] - 2026-03-30 — Comparison Board is the Chooser The design comparison board now always opens automatically when reviewing variants.
