fix: sidebar agent uses real tab URL instead of stale Playwright URL (v0.12.6.0) (#544) * fix: sidebar agent uses extension's activeTabUrl instead of stale Playwright URL When the user navigates manually in headed Chrome, Playwright's page.url() stays on the old page. The sidebar agent was using this stale URL in its system prompt, causing it to navigate to the wrong page (e.g., Hacker News instead of the user's current page). The Chrome extension now captures the active tab URL via chrome.tabs.query() and sends it as activeTabUrl in the /sidebar-command POST body. The server prefers this over Playwright's URL. The URL is sanitized (http/https only, control chars stripped, 2048 char limit) to prevent prompt injection.

Improves the onboarding flow with clearer instructions for finding the extension, opening the Side Panel, and troubleshooting connection issues. Fixes Mode check from cdp to headed. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: sidebar agent test suite (layers 1-2) Layer 1 (unit): 18 tests for URL sanitization in sidebar-utils.ts — http/https pass, chrome:// rejected, javascript: rejected, control chars stripped, truncation. Layer 2 (integration): 13 tests for server HTTP endpoints — auth, sidebar-command queue writes, activeTabUrl override/fallback, event relay to chat buffer, message queuing, queue overflow (429), chat clear, agent kill. Source changes for testability: - Extract sanitizeExtensionUrl() to browse/src/sidebar-utils.ts - Add BROWSE_HEADLESS_SKIP env var to skip browser launch in HTTP-only tests - Add SIDEBAR_QUEUE_PATH env var to both server.ts and sidebar-agent.ts - Add SIDEBAR_AGENT_TIMEOUT env var to sidebar-agent.ts - Sync package.json version to match VERSION (0.12.2.0) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: sidebar agent round-trip tests with mock claude (layer 3) Starts server + sidebar-agent together with a mock claude binary (shell script outputting canned stream-json). Verifies the full queue-based message flow: - Full round-trip: POST /sidebar-command → queue → agent → mock claude → events → chat - Claude crash recovery: mock exits 1, agent_error appears, status returns to idle - Sequential queue drain: two rapid messages both process in order Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: sidebar agent E2E tests with real Claude (layer 4) Two E2E tests that exercise the full sidebar agent flow with real Claude: - sidebar-navigate: POST /sidebar-command asking Claude to describe a fixture page, verify it responds with page content through the chat buffer - sidebar-url-accuracy: POST with activeTabUrl differing from Playwright URL, verify the queue prompt uses the extension URL (the core bug fix) Both registered as periodic tier (~$0.80 total, non-deterministic). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: sidebar E2E tests — sequential execution + eval collector fix Both tests now pass: - sidebar-url-accuracy: deterministic queue file check (no Claude needed) - sidebar-navigate: real Claude responds through sidebar agent queue Fixed: testIfSelected (sequential, not concurrent) to avoid queue file conflicts. Added cost_usd field for eval collector compatibility. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: kill stale sidebar-agent processes before starting new one Each /connect-chrome starts a new sidebar-agent subprocess with unref() but never kills the previous one. Old agents accumulate as zombies with stale auth tokens. When they pick up queue entries, their event relay fails (401), so the server never receives agent_done and marks the agent as "hung". The user sees the sidebar freeze. Fix: pkill any existing sidebar-agent.ts processes before spawning.
