Plan Mode Safe Operations

In plan mode, allowed because they inform the plan: $B, $D, codex exec/codex review, writes to ~/.gstack/, writes to the plan file, and open for generated artifacts.

Skill Invocation During Plan Mode

If the user invokes a skill in plan mode, the skill takes precedence over generic plan mode behavior. Treat the skill file as executable instructions, not reference. Follow it step by step starting from Step 0; the first AskUserQuestion is the workflow entering plan mode, not a violation of it. AskUserQuestion (any variant — mcp__*__AskUserQuestion or native; see "AskUserQuestion Format → Tool resolution") satisfies plan mode's end-of-turn requirement. If AskUserQuestion is unavailable or a call fails, follow the AskUserQuestion Format failure fallback: headless → BLOCKED; interactive → the prose fallback (also satisfies end-of-turn). At a STOP point, stop immediately. Do not continue the workflow or call ExitPlanMode there. Commands marked "PLAN MODE EXCEPTION — ALWAYS RUN" execute. Call ExitPlanMode only after the skill workflow completes, or if the user tells you to cancel the skill or leave plan mode.

If PROACTIVE is "false", do not auto-invoke or proactively suggest skills. If a skill seems useful, ask: "I think /skillname might help here — want me to run it?"

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

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 output shows JUST_UPGRADED <from> <to>: 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.

After upgrade prompts, continue workflow.

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

If A: leave explain_level unset (defaults to default). If B: run ~/.claude/skills/gstack/bin/gstack-config 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 Ocean 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 or file paths. Your repo name is recorded locally only and stripped before any upload.

Options:

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

If A: run ~/.claude/skills/gstack/bin/gstack-config set telemetry community

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

If B→A: run ~/.claude/skills/gstack/bin/gstack-config set telemetry anonymous If B→B: run ~/.claude/skills/gstack/bin/gstack-config set telemetry 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

If A: run ~/.claude/skills/gstack/bin/gstack-config set proactive true If B: run ~/.claude/skills/gstack/bin/gstack-config set proactive false

Always run:

touch ~/.gstack/.proactive-prompted

Skip if PROACTIVE_PROMPTED is yes.

First-run guidance (one-time)

If ACTIVATED is no (first skill run on this machine) AND the preamble printed a non-empty FIRST_TASK: value that is NOT nongit: show ONE short, project-specific line mapped from the token, as a heads-up, then CONTINUE with whatever the user actually asked — do NOT halt their task. Map the token: greenfield → "Fresh repo — shape it first with /spec or /office-hours." code_node/code_python/code_rust/code_go/code_ruby/code_ios → "There's code here — /qa to see it work, or /investigate if something's off." branch_ahead → "Unshipped work on this branch — /review then /ship." dirty_default → "Uncommitted changes — /review before committing." clean_default → "Pick one: /spec, /investigate, or /qa." Then substitute the token you saw for TASK_TOKEN and run (best-effort), and mark activated:

~/.claude/skills/gstack/bin/gstack-telemetry-log --event-type first_task_scaffold_shown --skill "TASK_TOKEN" --outcome shown 2>/dev/null || true
touch ~/.gstack/.activated 2>/dev/null || true

If ACTIVATED is no but FIRST_TASK: is empty or nongit (headless, non-git, or nothing actionable): show nothing, just run touch ~/.gstack/.activated 2>/dev/null || true.

Else if ACTIVATED is yes AND FIRST_LOOP_SHOWN is no: say once as a heads-up (then continue):

Tip: gstack pays off when you complete one loop — plan → review → ship. A common first loop: /office-hours or /spec to shape it, /plan-eng-review to lock it, then /ship.

Then run touch ~/.gstack/.first-loop-tip-shown 2>/dev/null || true.

Skip this section if ACTIVATED and FIRST_LOOP_SHOWN are both 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

If A: Append this section to the end of CLAUDE.md:

## 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
- Author a backlog-ready spec/issue → invoke /spec

Then commit the change: git add CLAUDE.md && git commit -m "chore: add gstack skill routing rules to CLAUDE.md"

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

If A:

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"

If B: say "OK, you're on your own to keep the vendored copy up to date."

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.

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

gstack can publish your artifacts (CEO plans, designs, reports) 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

After answer:

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

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

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.

Todo-list discipline. When working through a multi-step plan, mark each task complete individually as you finish it. Do not batch-complete at the end. If a task turns out to be unnecessary, mark it skipped with a one-line reason.

Think before heavy actions. For complex operations (refactors, migrations, non-trivial new features), briefly state your approach before executing. This lets the user course-correct cheaply instead of mid-flight.

Dedicated tools over Bash. Prefer Read, Edit, Write, Glob, Grep over shell equivalents (cat, sed, find, grep). The dedicated tools are cheaper and clearer.

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.

Escalate after 3 failed attempts, uncertain security-sensitive changes, or scope you cannot verify. Format: STATUS, REASON, ATTEMPTED, RECOMMENDATION.

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.

PLAN MODE EXCEPTION — ALWAYS RUN: This command writes telemetry to ~/.gstack/analytics/, matching preamble analytics writes.

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)

Replace SKILL_NAME, OUTCOME, and USED_BROWSE before running.

Plan Status Footer

Skills that run plan reviews (/plan-*-review, /codex review) include the EXIT PLAN MODE GATE blocking checklist at the end of the skill, which verifies the plan file ends with ## GSTACK REVIEW REPORT before ExitPlanMode is called. Skills that don't run plan reviews (operational skills like /ship, /qa, /review) typically don't operate in plan mode and have no review report to verify; this footer is a no-op for them. Writing the plan file is the one edit allowed in plan mode.

Setup Browser Cookies

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

CDP mode check

First, check if browse is already connected to the user's real browser:

$B status 2>/dev/null | grep -q "Mode: cdp" && echo "CDP_MODE=true" || echo "CDP_MODE=false"

If CDP_MODE=true: tell the user "Not needed — you're connected to your real browser via CDP. Your cookies and sessions are already available." and stop. No cookie import needed.

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 "$B" ] && B="$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 <SKILL_DIR> && ./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
   

2. Open the cookie picker

$B cookie-import-browser

This auto-detects installed Chromium browsers 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

• On macOS, the first import per browser may trigger a Keychain dialog — click "Allow" / "Always Allow"
• On Linux, v11 cookies may require secret-tool/libsecret access; v10 cookies use Chromium's standard fallback key
• 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
