Packet Test

Run an end-to-end AX.25 packet QSO test between two virtual rigs at 300 bd and 1200 bd, drive both browsers via Playwright MCP, screenshot both sides, and tear down. (9600 G3RUH is intentionally NOT tested by this skill.)

Prerequisites (verify before starting; fix and stop if missing)

1. ./wfweb and ./tools/virtualrig/virtualrig are built. If not, build with qmake wfweb.pro && make -j$(nproc) and cd tools/virtualrig && qmake && make -j$(nproc).
2. Repo .mcp.json includes --ignore-https-errors for the playwright MCP. wfweb's cert is self-signed; without this flag chromium refuses with ERR_CERT_AUTHORITY_INVALID. Verify the running MCP has the flag: pgrep -af @playwright/mcp must show --ignore-https-errors. If .mcp.json was just edited, the user needs to restart Claude Code (not just /mcp reconnect — that re-uses cached args). Stop and tell them.
3. The playwright tools live behind ToolSearch — load them with select:mcp__playwright__browser_navigate,mcp__playwright__browser_snapshot,mcp__playwright__browser_click,mcp__playwright__browser_type,mcp__playwright__browser_take_screenshot,mcp__playwright__browser_wait_for,mcp__playwright__browser_evaluate,mcp__playwright__browser_close,mcp__playwright__browser_tabs,mcp__playwright__browser_select_option.

Boot the bench

./scripts/testrig.sh up 2

Spawns virtualrig + 2 wfweb daemons. Both rigs come up on 14.074.000 USB by default — same freq, no --broadcast needed (audio-gating on matching freq+mode is what real packet does).

• A → https://127.0.0.1:9080 (virtual-IC7300-A)
• B → https://127.0.0.1:9090 (virtual-IC7300-B)

Per-tab UI bring-up (do for both A and B)

The Packet panel lives inside the MODE overlay — there is no top-level Packet button.

1. browser_navigate to the rig URL.
2. Wipe stale browser state. Playwright reuses its profile across runs, so localStorage carries activeTab, last-used callsign, and panel visibility — those have produced races that don't reproduce in real-world use. browser_evaluate () => { localStorage.clear(); sessionStorage.clear(); }, then browser_navigate to the same URL again so init runs against an empty store.
3. Click the CLICK TO START splash button (browsers refuse AudioContext without a user gesture).
4. Click MODE, then click Packet in the mode grid. Rig stays on USB (Packet IS USB on HF).
5. Click the gear (#packetSettingsBtn), type the callsign in the Callsign input, click Save.
   • A: W1AAA, B: W1BBB. Format must be valid amateur (letter+digit+letters). The single callsign is shared with CW/FT8/FreeDV/APRS — do not add per-mode callsigns.
6. Click the baud button for this iteration (#packetMode300 or #packetMode1200).
7. Click the TERMINAL tab.
8. On A only: clear #termPeerCall and type the other rig's callsign (W1BBB).

When refs go stale across snapshots, drive directly via browser_evaluate with stable IDs:

• Buttons: packetSettingsBtn, packetMode300, packetMode1200, packetClearBtn, termConnectBtn, termDisconnectBtn, termSendBtn
• Fields: termPeerCall, termInput
• State: document.getElementById('termStateChip').textContent (DISCONNECTED / CONNECTING / CONNECTED / DISCONNECTING)
• Object: window.Packet.state.{mode, terminal.sessions.t1.{state, scrollback, ownCall, peerCall}}

QSO sequence (run for each baud: 300, then 1200)

1. A → Connect: click #termConnectBtn. Poll termStateChip.textContent === 'CONNECTED' (a few seconds at 300, faster at 1200). Verify B also flips to CONNECTED and B's session scrollback gets *** CONNECTED to W1AAA.
2. A → "Hello": set termInput.value = 'Hello', click #termSendBtn. Wait on B for Hello to render.
3. B → "How are you": same pattern. Wait on A for the text.
4. Screenshot both with browser_take_screenshot, fullPage: true. Pass the full path as filename: .playwright-mcp/wfweb-packet-<baud>-A.png and ...-B.png. The MCP does NOT auto-target .playwright-mcp/ — bare filenames land in the project root (the MCP's CWD). Do not use /tmp — it's outside the MCP's allowed roots and will fail.
5. B → Disconnect: click #termDisconnectBtn. Both chips go to DISCONNECTED.
6. Before 1200 bd: click #packetMode1200 on both tabs, re-set #termPeerCall on A (it may revert to placeholder), and optionally wipe window.Packet.state.terminal.sessions.t1.scrollback = [] then click #packetTabTerm to re-render for a clean screenshot (renderTerm is not exported on window.Packet).
