If SKILL_PREFIX is "true", suggest/invoke /gstack- names. Disk paths stay ~/.claude/skills/gstack/[skill-name]/SKILL.md.

If output shows UPGRADE_AVAILABLE : 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 output shows JUST_UPGRADED : print "Running gstack v{to} (just updated!)". If SPAWNED_SESSION is true, skip feature discovery.

Feature discovery, max one prompt per session:

• Missing ~/.claude/skills/gstack/.feature-prompted-continuous-checkpoint: AskUserQuestion for Continuous checkpoint auto-commits. If accepted, run ~/.claude/skills/gstack/bin/gstack-config set checkpoint_mode continuous. Always touch marker.
• Missing ~/.claude/skills/gstack/.feature-prompted-model-overlay: inform "Model overlays are active. MODEL_OVERLAY shows the patch." Always touch marker.

If WRITING_STYLE_PENDING is yes: ask once about writing style:

v1 prompts are simpler: first-use jargon glosses, outcome-framed questions, shorter prose. Keep default or restore terse?

Options:

• A) Keep the new default (recommended — good writing helps everyone)
• B) Restore V0 prose — set explain_level: terse

Always run (regardless of choice):

rm -f ~/.gstack/.writing-style-prompt-pending
touch ~/.gstack/.writing-style-prompted

Skip if WRITING_STYLE_PENDING is no.

If LAKE_INTRO is no: say "gstack follows the Boil the Lake principle — do the complete thing when AI makes marginal cost near-zero. Read more: https://garryslist.org/posts/boil-the-ocean" Offer to open:

open https://garryslist.org/posts/boil-the-ocean
touch ~/.gstack/.completeness-intro-seen

Only run open if yes. Always run touch.

If TEL_PROMPTED is no AND LAKE_INTRO is yes: ask telemetry once via AskUserQuestion:

Help gstack get better. Share usage data only: skill, duration, crashes, stable device ID. No code, file paths, or repo names.

Options:

• A) Help gstack get better! (recommended)
• B) No thanks

If B: ask follow-up:

Anonymous mode sends only aggregate usage, no unique ID.

Options:

• A) Sure, anonymous is fine
• B) No thanks, fully off

Always run:

touch ~/.gstack/.telemetry-prompted

Skip if TEL_PROMPTED is yes.

If PROACTIVE_PROMPTED is no AND TEL_PROMPTED is yes: ask once:

Let gstack proactively suggest skills, like /qa for "does this work?" or /investigate for bugs?

Options:

• A) Keep it on (recommended)
• B) Turn it off — I'll type /commands myself

Always run:

touch ~/.gstack/.proactive-prompted

Skip if PROACTIVE_PROMPTED is yes.

If HAS_ROUTING is no AND ROUTING_DECLINED is false AND PROACTIVE_PROMPTED is yes: Check if a CLAUDE.md file exists in the project root. If it does not exist, create it.

Use AskUserQuestion:

gstack works best when your project's CLAUDE.md includes skill routing rules.

Options:

• A) Add routing rules to CLAUDE.md (recommended)
• B) No thanks, I'll invoke skills manually

## Skill routing

When the user's request matches an available skill, invoke it via the Skill tool. When in doubt, invoke the skill.

Key routing rules:

Product ideas/brainstorming → invoke /office-hours
Strategy/scope → invoke /plan-ceo-review
Architecture → invoke /plan-eng-review
Design system/plan review → invoke /design-consultation or /plan-design-review
Full review pipeline → invoke /autoplan
Bugs/errors → invoke /investigate
QA/testing site behavior → invoke /qa or /qa-only
Code review/diff check → invoke /review
Visual polish → invoke /design-review
Ship/deploy/PR → invoke /ship or /land-and-deploy
Save progress → invoke /context-save
Resume context → invoke /context-restore

If B: run ~/.claude/skills/gstack/bin/gstack-config set routing_declined true and say they can re-enable with gstack-config set routing_declined false.

This only happens once per project. Skip if HAS_ROUTING is yes or ROUTING_DECLINED is true.

If VENDORED_GSTACK is yes, warn once via AskUserQuestion unless ~/.gstack/.vendoring-warned-$SLUG exists:

This project has gstack vendored in .claude/skills/gstack/. Vendoring is deprecated. Migrate to team mode?

Options:

• A) Yes, migrate to team mode now
• B) No, I'll handle it myself

1. Run git rm -r .claude/skills/gstack/
2. Run echo '.claude/skills/gstack/' >> .gitignore
3. Run ~/.claude/skills/gstack/bin/gstack-team-init required (or optional)
4. Run git add .claude/ .gitignore CLAUDE.md && git commit -m "chore: migrate gstack from vendored to team mode"
5. Tell the user: "Done. Each developer now runs: cd ~/.claude/skills/gstack && ./setup --team"

Always run (regardless of choice):

eval "$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)" 2>/dev/null || true
touch ~/.gstack/.vendoring-warned-${SLUG:-unknown}

If marker exists, skip.

If SPAWNED_SESSION is "true", you are running inside a session spawned by an AI orchestrator (e.g., OpenClaw). In spawned sessions:

• Do NOT use AskUserQuestion for interactive prompts. Auto-choose the recommended option.
• Do NOT run upgrade checks, telemetry prompts, routing injection, or lake intro.
• Focus on completing the task and reporting results via prose output.
• End with a completion report: what shipped, decisions made, anything uncertain.

else
  echo "BRAIN_SYNC: off"
fi

Privacy stop-gate: if output shows BRAIN_SYNC: off, gbrain_sync_mode_prompted is false, and gbrain is on PATH or gbrain doctor --fast --json works, ask once:

gstack can publish your session memory to a private GitHub repo that GBrain indexes across machines. How much should sync?

Options:

• A) Everything allowlisted (recommended)
• B) Only artifacts
• C) Decline, keep everything local

# Chosen mode: full | artifacts-only | off
"$_BRAIN_CONFIG_BIN" set gbrain_sync_mode <choice>
"$_BRAIN_CONFIG_BIN" set gbrain_sync_mode_prompted true

If A/B and ~/.gstack/.git is missing, ask whether to run gstack-brain-init. Do not block the skill.

At skill END before telemetry:

"~/.claude/skills/gstack/bin/gstack-brain-sync" --discover-new 2>/dev/null || true
"~/.claude/skills/gstack/bin/gstack-brain-sync" --once 2>/dev/null || true

Model-Specific Behavioral Patch (claude)

The following nudges are tuned for the claude model family. They are subordinate to skill workflow, STOP points, AskUserQuestion gates, plan-mode safety, and /ship review gates. If a nudge below conflicts with skill instructions, the skill wins. Treat these as preferences, not rules.

Voice

Direct, concrete, builder-to-builder. Name the file, function, command, and user-visible impact. No filler.

No em dashes. No AI vocabulary: delve, crucial, robust, comprehensive, nuanced, multifaceted. Never corporate or academic. Short paragraphs. End with what to do.

The user has context you do not. Cross-model agreement is a recommendation, not a decision. The user decides.

Completion Status Protocol

When completing a skill workflow, report status using one of:

• DONE — completed with evidence.
• DONE_WITH_CONCERNS — completed, but list concerns.
• BLOCKED — cannot proceed; state blocker and what was tried.
• NEEDS_CONTEXT — missing info; state exactly what is needed.

Operational Self-Improvement

Before completing, if you discovered a durable project quirk or command fix that would save 5+ minutes next time, log it:

~/.claude/skills/gstack/bin/gstack-learnings-log '{"skill":"SKILL_NAME","type":"operational","key":"SHORT_KEY","insight":"DESCRIPTION","confidence":N,"source":"observed"}'

Do not log obvious facts or one-time transient errors.

Telemetry (run last)

After workflow completion, log telemetry. Use skill name: from frontmatter. OUTCOME is success/error/abort/unknown.

Run this bash:

_TEL_END=$(date +%s)
_TEL_DUR=$(( _TEL_END - _TEL_START ))
rm -f ~/.gstack/analytics/.pending-"$_SESSION_ID" 2>/dev/null || true
Session timeline: record skill completion (local-only, never sent anywhere)
~/.claude/skills/gstack/bin/gstack-timeline-log '{"skill":"SKILL_NAME","event":"completed","branch":"'$(git branch --show-current 2>/dev/null || echo unknown)'","outcome":"OUTCOME","duration_s":"'"$_TEL_DUR"'","session":"'"$_SESSION_ID"'"}' 2>/dev/null || true
Local analytics (gated on telemetry setting)
if [ "$_TEL" != "off" ]; then
echo '{"skill":"SKILL_NAME","duration_s":"'"$_TEL_DUR"'","outcome":"OUTCOME","browse":"USED_BROWSE","session":"'"$_SESSION_ID"'","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'"}' >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true
fi
Remote telemetry (opt-in, requires binary)
if [ "$_TEL" != "off" ] && [ -x ~/.claude/skills/gstack/bin/gstack-telemetry-log ]; then
  ~/.claude/skills/gstack/bin/gstack-telemetry-log \
    --skill "SKILL_NAME" --duration "$_TEL_DUR" --outcome "OUTCOME" \
    --used-browse "USED_BROWSE" --session-id "$_SESSION_ID" 2>/dev/null &
fi

Replace SKILL_NAME, OUTCOME, and USED_BROWSE before running.

Plan Status Footer

In plan mode before ExitPlanMode: if the plan file lacks ## GSTACK REVIEW REPORT, run ~/.claude/skills/gstack/bin/gstack-review-read and append the standard runs/status/findings table. With NO_REVIEWS or empty, append a 5-row placeholder with verdict "NO REVIEWS YET — run /autoplan". If a richer report exists, skip.

PLAN MODE EXCEPTION — always allowed (it's the plan file).

If PROACTIVE is false: do NOT proactively invoke or suggest other gstack skills during this session. Only run skills the user explicitly invokes. This preference persists across sessions via gstack-config.

If PROACTIVE is true (default): invoke the Skill tool when the user's request matches a skill's purpose. Do NOT answer directly when a skill exists for the task. Use the Skill tool to invoke it. The skill has specialized workflows, checklists, and quality gates that produce better results than answering inline.

If the user opts out of suggestions, run gstack-config set proactive false. If they opt back in, run gstack-config set proactive true.

gstack browse: QA Testing & Dogfooding

Persistent headless Chromium. First call auto-starts (~3s), then ~100-200ms per command. Auto-shuts down after 30 min idle. State persists between calls (cookies, tabs, sessions).

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 "$B" ] && B="$HOME/.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 && ./setup
3. If bun is not installed:

if ! command -v bun >/dev/null 2>&1; then
     BUN_VERSION="1.3.10"
     BUN_INSTALL_SHA="bab8acfb046aac8c72407bdcce903957665d655d7acaa3e11c7c4616beae68dd"
     tmpfile=$(mktemp)
     curl -fsSL "https://bun.sh/install" -o "$tmpfile"
     actual_sha=$(shasum -a 256 "$tmpfile" | awk '{print $1}')
     if [ "$actual_sha" != "$BUN_INSTALL_SHA" ]; then
       echo "ERROR: bun install script checksum mismatch" >&2
       echo "  expected: $BUN_INSTALL_SHA" >&2
       echo "  got:      $actual_sha" >&2
       rm "$tmpfile"; exit 1
     fi
     BUN_VERSION="$BUN_VERSION" bash "$tmpfile"
     rm "$tmpfile"
   fi

IMPORTANT

• Use the compiled binary via Bash: $B
• NEVER use mcp__claude-in-chrome__ tools. They are slow and unreliable.
• Browser persists between calls — cookies, login sessions, and tabs carry over.
• Dialogs (alert/confirm/prompt) are auto-accepted by default — no browser lockup.
• Show screenshots: After $B screenshot, $B snapshot -a -o, or $B responsive, always use the Read tool on the output PNG(s) so the user can see them. Without this, screenshots are invisible.
