78e519e3 — Garry Tan feat: await support in browse js/eval + contributor mode v2 (#104) a month ago

name: setup-browser-cookies version: 1.0.0 description: | Import cookies from your real browser (Comet, Chrome, Arc, Brave, Edge) into the headless browse session. Opens an interactive picker UI where you select which cookie domains to import. Use before QA testing authenticated pages. allowed-tools:

  • Bash
  • Read
  • AskUserQuestion

#Preamble (run first)

_UPD=$(~/.claude/skills/gstack/bin/gstack-update-check 2>/dev/null || .claude/skills/gstack/bin/gstack-update-check 2>/dev/null || true)
[ -n "$_UPD" ] && echo "$_UPD" || true
mkdir -p ~/.gstack/sessions
touch ~/.gstack/sessions/"$PPID"
_SESSIONS=$(find ~/.gstack/sessions -mmin -120 -type f 2>/dev/null | wc -l | tr -d ' ')
find ~/.gstack/sessions -mmin +120 -type f -delete 2>/dev/null || true
_CONTRIB=$(~/.claude/skills/gstack/bin/gstack-config get gstack_contributor 2>/dev/null || true)

If output shows UPGRADE_AVAILABLE <old> <new>: read ~/.claude/skills/gstack/gstack-upgrade/SKILL.md and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If JUST_UPGRADED <from> <to>: tell user "Running gstack v{to} (just updated!)" and continue.

#AskUserQuestion Format

ALWAYS follow this structure for every AskUserQuestion call:

  1. Context: project name, current branch, what we're working on (1-2 sentences)
  2. The specific question or decision point
  3. RECOMMENDATION: Choose [X] because [one-line reason]
  4. Lettered options: A) ... B) ... C) ...

If _SESSIONS is 3 or more: the user is juggling multiple gstack sessions and context-switching heavily. ELI16 mode — they may not remember what this conversation is about. Every AskUserQuestion MUST re-ground them: state the project, the branch, the current plan/task, then the specific problem, THEN the recommendation and options. Be extra clear and self-contained — assume they haven't looked at this window in 20 minutes.

Per-skill instructions may add additional formatting rules on top of this baseline.

#Contributor Mode

If _CONTRIB is true: you are in contributor mode. You're a gstack user who also helps make it better.

At the end of each major workflow step (not after every single command), reflect on the gstack tooling you used. Rate your experience 0 to 10. If it wasn't a 10, think about why. If there is an obvious, actionable bug OR an insightful, interesting thing that could have been done better by gstack code or skill markdown — file a field report. Maybe our contributor will help make us better!

Calibration — this is the bar: For example, $B js "await fetch(...)" used to fail with SyntaxError: await is only valid in async functions because gstack didn't wrap expressions in async context. Small, but the input was reasonable and gstack should have handled it — that's the kind of thing worth filing. Things less consequential than this, ignore.

NOT worth filing: user's app bugs, network errors to user's URL, auth failures on user's site, user's own JS logic bugs.

To file: write ~/.gstack/contributor-logs/{slug}.md with all sections below (do not truncate — include every section through the Date/Version footer):

# {Title}

Hey gstack team — ran into this while using /{skill-name}:

**What I was trying to do:** {what the user/agent was attempting}
**What happened instead:** {what actually happened}
**My rating:** {0-10} — {one sentence on why it wasn't a 10}

## Steps to reproduce
1. {step}

## Raw output

{paste the actual error or unexpected output here}


## What would make this a 10
{one sentence: what gstack should have done differently}

**Date:** {YYYY-MM-DD} | **Version:** {gstack version} | **Skill:** /{skill}

Slug: lowercase, hyphens, max 60 chars (e.g. browse-js-no-await). Skip if file already exists. Max 3 reports per session. File inline and continue — don't stop the workflow. Tell user: "Filed gstack field report: {title}"

#Setup Browser Cookies

Import logged-in sessions from your real Chromium browser into the headless browse session.

#How it works

  1. Find the browse binary
  2. Run cookie-import-browser to detect installed browsers and open the picker UI
  3. User selects which cookie domains to import in their browser
  4. Cookies are decrypted and loaded into the Playwright session

#Steps

#1. Find the browse binary

#SETUP (run this check BEFORE any browse command)

_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
B=""
[ -n "$_ROOT" ] && [ -x "$_ROOT/.claude/skills/gstack/browse/dist/browse" ] && B="$_ROOT/.claude/skills/gstack/browse/dist/browse"
[ -z "$B" ] && B=~/.claude/skills/gstack/browse/dist/browse
if [ -x "$B" ]; then
  echo "READY: $B"
else
  echo "NEEDS_SETUP"
fi

If NEEDS_SETUP:

  1. Tell the user: "gstack browse needs a one-time build (~10 seconds). OK to proceed?" Then STOP and wait.
  2. Run: cd <SKILL_DIR> && ./setup
  3. If bun is not installed: curl -fsSL https://bun.sh/install | bash
$B cookie-import-browser

This auto-detects installed Chromium browsers (Comet, Chrome, Arc, Brave, Edge) and opens an interactive picker UI in your default browser where you can:

  • Switch between installed browsers
  • Search domains
  • Click "+" to import a domain's cookies
  • Click trash to remove imported cookies

Tell the user: "Cookie picker opened — select the domains you want to import in your browser, then tell me when you're done."

#3. Direct import (alternative)

If the user specifies a domain directly (e.g., /setup-browser-cookies github.com), skip the UI:

$B cookie-import-browser comet --domain github.com

Replace comet with the appropriate browser if specified.

#4. Verify

After the user confirms they're done:

$B cookies

Show the user a summary of imported cookies (domain counts).

#Notes

  • First import per browser may trigger a macOS Keychain dialog — click "Allow" / "Always Allow"
  • Cookie picker is served on the same port as the browse server (no extra process)
  • Only domain names and cookie counts are shown in the UI — no cookie values are exposed
  • The browse session persists cookies between commands, so imported cookies work immediately
