Fast headless browser for QA testing and site dogfooding. Navigate any URL, interact with elements, verify page state, diff before/after actions, take annotated screenshots, check responsive layouts, test forms and uploads, handle dialogs, and assert element states. ~100ms per command. Use when you need to test a feature, verify a deployment, dogfood a user flow, or file a bug with evidence.
CEO/founder-mode plan review. Rethink the problem, find the 10-star product, challenge premises, expand scope when it creates a better product. Three modes: SCOPE EXPANSION (dream big), HOLD SCOPE (maximum rigor), SCOPE REDUCTION (strip to essentials).
Eng manager-mode plan review. Lock in the execution plan — architecture, data flow, diagrams, edge cases, test coverage, performance. Walks through issues interactively with opinionated recommendations.
Systematically QA test a web application. Use when asked to "qa", "QA", "test this site", "find bugs", "dogfood", or review quality. Four modes: diff-aware (automatic on feature branches — analyzes git diff, identifies affected pages, tests them), full (systematic exploration), quick (30-second smoke test), regression (compare against baseline). Produces structured report with health score, screenshots, and repro steps.
Weekly engineering retrospective. Analyzes commit history, work patterns, and code quality metrics with persistent history and trend tracking. Team-aware: breaks down per-person contributions with praise and growth areas.
Pre-landing PR review. Analyzes diff against main for SQL safety, LLM trust boundary violations, conditional side effects, and other structural issues.

Upgrade gstack to the latest version and show what's new.
This section is referenced by all skill preambles when they detect UPGRADE_AVAILABLE.
Use AskUserQuestion:
If "Later": Run touch ~/.gstack/last-update-check to reset the 24h timer and continue with the current skill. Do not mention the upgrade again.
if [ -d "$HOME/.claude/skills/gstack/.git" ]; then
INSTALL_TYPE="global-git"
INSTALL_DIR="$HOME/.claude/skills/gstack"
elif [ -d ".claude/skills/gstack/.git" ]; then
INSTALL_TYPE="local-git"
INSTALL_DIR=".claude/skills/gstack"
elif [ -d ".claude/skills/gstack" ]; then
INSTALL_TYPE="vendored"
INSTALL_DIR=".claude/skills/gstack"
elif [ -d "$HOME/.claude/skills/gstack" ]; then

echo "ERROR: gstack not found"
exit 1
fi
echo "Install type: $INSTALL_TYPE at $INSTALL_DIR"
OLD_VERSION=$(cat "$INSTALL_DIR/VERSION" 2>/dev/null || echo "unknown")
For git installs (global-git, local-git):
cd "$INSTALL_DIR"
STASH_OUTPUT=$(git stash 2>&1)
git fetch origin
git reset --hard origin/main
./setup
If $STASH_OUTPUT contains "Saved working directory", warn the user: "Note: local changes were stashed. Run git stash pop in the skill directory to restore them."
For vendored installs (vendored, vendored-global):
PARENT=$(dirname "$INSTALL_DIR")
TMP_DIR=$(mktemp -d)
git clone --depth 1 https://github.com/garrytan/gstack.git "$TMP_DIR/gstack"
mv "$INSTALL_DIR" "$INSTALL_DIR.bak"
mv "$TMP_DIR/gstack" "$INSTALL_DIR"
cd "$INSTALL_DIR" && ./setup
rm -rf "$INSTALL_DIR.bak" "$TMP_DIR"
mkdir -p ~/.gstack
echo "$OLD_VERSION" > ~/.gstack/just-upgraded-from
rm -f ~/.gstack/last-update-check
Read $INSTALL_DIR/CHANGELOG.md. Find all version entries between the old version and the new version. Summarize as 5-7 bullets grouped by theme. Don't overwhelm — focus on user-facing changes. Skip internal refactors unless they're significant.
Format:
gstack v{new} — upgraded from v{old}!
What's new:
- [bullet 1]
- [bullet 2]
- ...
Happy shipping!
After showing What's New, continue with whatever skill the user originally invoked. The upgrade is done — no further action needed.
When invoked directly as /gstack-upgrade (not from a preamble), follow Steps 2-6 above. If already on the latest version, tell the user: "You're already on the latest version (v{version})."
