Bead: `6966f467-4993-4cc0-b148-72bb348d5990`. Verbatim user prompts; assistant turns summarized with pointers.
## Pre-bead context **User:** "are you able to see what chrome tabs are open per window?" Assistant explained three routes: SNSS session-file parse (no setup, messy binary, lags live state), DevTools `--remote-debugging-port=9222` (clean live JSON but needs relaunch), and the window-grouping caveat (extension API is the only clean per-window source). **User:** "yes try parsing" Assistant wrote `C:\Users\steph\Downloads\parse_snss.py` (stdlib-only SNSS parser: reads `SetTabWindow`, `SetTabIndexInWindow`, `UpdateTabNavigation`, `WindowClosed`, `SetActiveWindow` commands; pickle string/string16 with 4-byte alignment; groups tabs by window, current URL = highest nav index). The live `Session_*` file was exclusively locked by Chrome (plain `cp`, `FileShare.ReadWrite` shared-read both refused). Fell back to the newest **readable** session file (`Session_13425762157319581`, 12:28 — ~4 min stale). Recovered **11 windows / ~59 tabs**, active window id `2116059470` = window #10 with 15 tabs.
## Bead session **User:** "start-bead that will be about chrome tab manager. the first skill will be making a slideshow maker. for now make an html slide show for #10 with 15 tabs. make them iframes with slide advance buttons and the an open button to open the iframe in its own new window. make it an artifact and then sync the bead.." Assistant actions: - Read `.agents/beads.md` for the canonical protocol + root-file template. - Re-ran the parser to dump **full** (untruncated) URLs for the active window → `C:\Users\steph\Downloads\active_window_tabs.json` (tabs 4/5/11 had been truncated to 110 chars in the first print). - Generated GUID `6966f467-4993-4cc0-b148-72bb348d5990`; scaffolded the bead (`about.md`, `README.md`, dated `artifacts/`, `chats/`, `notes/`, `skills/`). - Built `artifacts/window-10-slideshow.html`: single-file, 15 tabs as one reused lazy iframe, prev/next buttons + ←/→ keys, numbered thumb strip, per-tab "⧉ Open in new window" (`window.open(url,'_blank','noopener')`), and a heuristic X-Frame-Options/CSP "blocked" overlay that offers the open-in-new-window escape hatch (Amazon, jwt.io, Google, some simtable pages refuse framing). - Ran `/bead-sync` to push the bead to its canonical URI. ### Notes for replay - Window-grouping is reconstructed from `SetTabWindow`, not authoritative. - Snapshot is the freshest *readable* SNSS file; the truly-live file is locked. Exact-current needs `--remote-debugging-port=9222`.
