## Plan Mode Safe Operations

In plan mode, these are always allowed (they inform the plan, don't modify source):
`$B` (browse), `$D` (design), `codex exec`/`codex review`, writes to `~/.gstack/`,
writes to the plan file, `open` for generated artifacts.

## Skill Invocation During Plan Mode

If the user invokes a skill in plan mode, that skill takes precedence over generic plan mode behavior. Treat it as executable instructions, not reference. Follow step
by step. AskUserQuestion calls satisfy plan mode's end-of-turn requirement. At a STOP
point, stop immediately. Do not continue the workflow past a STOP point and do not call ExitPlanMode there. Commands marked "PLAN
MODE EXCEPTION — ALWAYS RUN" execute. Other writes need to be already permitted
above or explicitly exception-marked. Call ExitPlanMode only after the skill
workflow completes — only then call ExitPlanMode (or if the user tells you to cancel the skill or leave plan mode).

If `PROACTIVE` is `"false"`, do not proactively suggest gstack skills AND do not
auto-invoke skills based on conversation context. Only run skills the user explicitly
types (e.g., /qa, /ship). If you would have auto-invoked a skill, instead briefly say:
"I think /skillname might help here — want me to run it?" and wait for confirmation.
The user opted out of proactive behavior.

If `SKILL_PREFIX` is `"true"`, the user has namespaced skill names. When suggesting
or invoking other gstack skills, use the `/gstack-` prefix (e.g., `/gstack-qa` instead
of `/qa`, `/gstack-ship` instead of `/ship`). Disk paths are unaffected — always use
`~/.claude/skills/gstack/[skill-name]/SKILL.md` for reading skill files.

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>` AND `SPAWNED_SESSION` is NOT set: tell
the user "Running gstack v{to} (just updated!)" and then check for new features to
surface. For each per-feature marker below, if the marker file is missing AND the
feature is plausibly useful for this user, use AskUserQuestion to let them try it.
Fire once per feature per user, NOT once per upgrade.

**In spawned sessions (`SPAWNED_SESSION` = "true"): SKIP feature discovery entirely.**
Just print "Running gstack v{to}" and continue. Orchestrators do not want interactive
prompts from sub-sessions.

**Feature discovery markers and prompts** (one at a time, max one per session):

1. `~/.claude/skills/gstack/.feature-prompted-continuous-checkpoint` →
   Prompt: "Continuous checkpoint auto-commits your work as you go with `WIP:` prefix
   so you never lose progress to a crash. Local-only by default — doesn't push
   anywhere unless you turn that on. Want to try it?"
   Options: A) Enable continuous mode, B) Show me first (print the section from
   the preamble Continuous Checkpoint Mode), C) Skip.
   If A: run `~/.claude/skills/gstack/bin/gstack-config set checkpoint_mode continuous`.
   Always: `touch ~/.claude/skills/gstack/.feature-prompted-continuous-checkpoint`

2. `~/.claude/skills/gstack/.feature-prompted-model-overlay` →
   Inform only (no prompt): "Model overlays are active. `MODEL_OVERLAY: {model}`
   shown in the preamble output tells you which behavioral patch is applied.
   Override with `--model` when regenerating skills (e.g., `bun run gen:skill-docs
   --model gpt-5.4`). Default is claude."
   Always: `touch ~/.claude/skills/gstack/.feature-prompted-model-overlay`

After handling JUST_UPGRADED (prompts done or skipped), continue with the skill
workflow.

If `WRITING_STYLE_PENDING` is `yes`: You're on the first skill run after upgrading
to gstack v1. Ask the user once about the new default writing style. Use AskUserQuestion:

> v1 prompts = simpler. Technical terms get a one-sentence gloss on first use,
> questions are framed in outcome terms, sentences are shorter.
>
> Keep the new default, or prefer the older tighter prose?

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):
```bash
rm -f ~/.gstack/.writing-style-prompt-pending
touch ~/.gstack/.writing-style-prompted
```

This only happens once. If `WRITING_STYLE_PENDING` is `no`, skip this entirely.

If `LAKE_INTRO` is `no`: Before continuing, introduce the Completeness Principle.
Tell the user: "gstack follows the **Boil the Lake** principle — always do the complete
thing when AI makes the marginal cost near-zero. Read more: https://garryslist.org/posts/boil-the-ocean"
Then offer to open the essay in their default browser:

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

Only run `open` if the user says yes. Always run `touch` to mark as seen. This only happens once.

If `TEL_PROMPTED` is `no` AND `LAKE_INTRO` is `yes`: After the lake intro is handled,
ask the user about telemetry. Use AskUserQuestion:

> Help gstack get better! Community mode shares usage data (which skills you use, how long
> they take, crash info) with a stable device ID so we can track trends and fix bugs faster.
> No code, file paths, or repo names are ever sent.
> Change anytime with `gstack-config set telemetry off`.

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 a follow-up AskUserQuestion:

> How about anonymous mode? We just learn that *someone* used gstack — no unique ID,
> no way to connect sessions. Just a counter that helps us know if anyone's out there.

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:
```bash
touch ~/.gstack/.telemetry-prompted
```

This only happens once. If `TEL_PROMPTED` is `yes`, skip this entirely.

If `PROACTIVE_PROMPTED` is `no` AND `TEL_PROMPTED` is `yes`: After telemetry is handled,
ask the user about proactive behavior. Use AskUserQuestion:

> gstack can proactively figure out when you might need a skill while you work —
> like suggesting /qa when you say "does this work?" or /investigate when you hit
> a bug. We recommend keeping this on — it speeds up every part of your workflow.

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:
```bash
touch ~/.gstack/.proactive-prompted
```

This only happens once. If `PROACTIVE_PROMPTED` is `yes`, skip this entirely.

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.
> This tells Claude to use specialized workflows (like /ship, /investigate, /qa)
> instead of answering directly. It's a one-time addition, about 15 lines.

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:

```markdown

## Skill routing

When the user's request matches an available skill, invoke it via the Skill tool. The
skill has multi-step workflows, checklists, and quality gates that produce better
results than an ad-hoc answer. When in doubt, invoke the skill. A false positive is
cheaper than a false negative.

Key routing rules:
- Product ideas, "is this worth building", brainstorming → invoke /office-hours
- Strategy, scope, "think bigger", "what should we build" → invoke /plan-ceo-review
- Architecture, "does this design make sense" → invoke /plan-eng-review
- Design system, brand, "how should this look" → invoke /design-consultation
- Design review of a plan → invoke /plan-design-review
- Developer experience of a plan → invoke /plan-devex-review
- "Review everything", full review pipeline → invoke /autoplan
- Bugs, errors, "why is this broken", "wtf", "this doesn't work" → invoke /investigate
- Test the site, find bugs, "does this work" → invoke /qa (or /qa-only for report only)
- Code review, check the diff, "look at my changes" → invoke /review
- Visual polish, design audit, "this looks off" → invoke /design-review
- Developer experience audit, try onboarding → invoke /devex-review
- Ship, deploy, create a PR, "send it" → invoke /ship
- Merge + deploy + verify → invoke /land-and-deploy
- Configure deployment → invoke /setup-deploy
- Post-deploy monitoring → invoke /canary
- Update docs after shipping → invoke /document-release
- Weekly retro, "how'd we do" → invoke /retro
- Second opinion, codex review → invoke /codex
- Safety mode, careful mode, lock it down → invoke /careful or /guard
- Restrict edits to a directory → invoke /freeze or /unfreeze
- Upgrade gstack → invoke /gstack-upgrade
- Save progress, "save my work" → invoke /context-save
- Resume, restore, "where was I" → invoke /context-restore
- Security audit, OWASP, "is this secure" → invoke /cso
- Make a PDF, document, publication → invoke /make-pdf
- Launch real browser for QA → invoke /open-gstack-browser
- Import cookies for authenticated testing → invoke /setup-browser-cookies
- Performance regression, page speed, benchmarks → invoke /benchmark
- Review what gstack has learned → invoke /learn
- Tune question sensitivity → invoke /plan-tune
- Code quality dashboard → invoke /health
```

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`
Say "No problem. You can add routing rules later by running `gstack-config set routing_declined false` and re-running any skill."

This only happens once per project. If `HAS_ROUTING` is `yes` or `ROUTING_DECLINED` is `true`, skip this entirely.

If `VENDORED_GSTACK` is `yes`: This project has a vendored copy of gstack at
`.claude/skills/gstack/`. Vendoring is deprecated. We will not keep vendored copies
up to date, so this project's gstack will fall behind.

Use AskUserQuestion (one-time per project, check for `~/.gstack/.vendoring-warned-$SLUG` marker):

> This project has gstack vendored in `.claude/skills/gstack/`. Vendoring is deprecated.
> We won't keep this copy up to date, so you'll fall behind on new features and fixes.
>
> Want to migrate to team mode? It takes about 30 seconds.

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

This only happens once per project. If the marker file exists, skip entirely.

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.

## GBrain Sync (skill start)

```bash
# gbrain-sync: drain pending writes, pull once per day. Silent no-op when
# the feature isn't initialized or gbrain_sync_mode is "off". See
# docs/gbrain-sync.md.

_GSTACK_HOME="${GSTACK_HOME:-$HOME/.gstack}"
_BRAIN_REMOTE_FILE="$HOME/.gstack-brain-remote.txt"
_BRAIN_SYNC_BIN="~/.claude/skills/gstack/bin/gstack-brain-sync"
_BRAIN_CONFIG_BIN="~/.claude/skills/gstack/bin/gstack-config"

_BRAIN_SYNC_MODE=$("$_BRAIN_CONFIG_BIN" get gbrain_sync_mode 2>/dev/null || echo off)

# New-machine hint: URL file present, local .git missing, sync not yet enabled.
if [ -f "$_BRAIN_REMOTE_FILE" ] && [ ! -d "$_GSTACK_HOME/.git" ] && [ "$_BRAIN_SYNC_MODE" = "off" ]; then
  _BRAIN_NEW_URL=$(head -1 "$_BRAIN_REMOTE_FILE" 2>/dev/null | tr -d '[:space:]')
  if [ -n "$_BRAIN_NEW_URL" ]; then
    echo "BRAIN_SYNC: brain repo detected: $_BRAIN_NEW_URL"
    echo "BRAIN_SYNC: run 'gstack-brain-restore' to pull your cross-machine memory (or 'gstack-config set gbrain_sync_mode off' to dismiss forever)"
  fi
fi

# Active-sync path.
if [ -d "$_GSTACK_HOME/.git" ] && [ "$_BRAIN_SYNC_MODE" != "off" ]; then
  # Once-per-day pull.
  _BRAIN_LAST_PULL_FILE="$_GSTACK_HOME/.brain-last-pull"
  _BRAIN_NOW=$(date +%s)
  _BRAIN_DO_PULL=1
  if [ -f "$_BRAIN_LAST_PULL_FILE" ]; then
    _BRAIN_LAST=$(cat "$_BRAIN_LAST_PULL_FILE" 2>/dev/null || echo 0)
    _BRAIN_AGE=$(( _BRAIN_NOW - _BRAIN_LAST ))
    [ "$_BRAIN_AGE" -lt 86400 ] && _BRAIN_DO_PULL=0
  fi
  if [ "$_BRAIN_DO_PULL" = "1" ]; then
    ( cd "$_GSTACK_HOME" && git fetch origin >/dev/null 2>&1 && git merge --ff-only "origin/$(git rev-parse --abbrev-ref HEAD)" >/dev/null 2>&1 ) || true
    echo "$_BRAIN_NOW" > "$_BRAIN_LAST_PULL_FILE"
  fi
  # Drain pending queue, push.
  "$_BRAIN_SYNC_BIN" --once 2>/dev/null || true
fi

# Status line — always emitted, easy to grep.
if [ -d "$_GSTACK_HOME/.git" ] && [ "$_BRAIN_SYNC_MODE" != "off" ]; then
  _BRAIN_QUEUE_DEPTH=0
  [ -f "$_GSTACK_HOME/.brain-queue.jsonl" ] && _BRAIN_QUEUE_DEPTH=$(wc -l < "$_GSTACK_HOME/.brain-queue.jsonl" | tr -d ' ')
  _BRAIN_LAST_PUSH="never"

else
  echo "BRAIN_SYNC: off"
fi
```



**Privacy stop-gate (fires ONCE per machine).**

If the bash output shows `BRAIN_SYNC: off` AND the config value
`gbrain_sync_mode_prompted` is `false` AND gbrain is detected on this host
(either `gbrain doctor --fast --json` succeeds or the `gbrain` binary is in PATH),
fire a one-time privacy gate via AskUserQuestion:

> gstack can publish your session memory (learnings, plans, designs, retros) to a
> private GitHub repo that GBrain indexes across your machines. Higher tiers
> include behavioral data (session timelines, developer profile). How much do you
> want to sync?

Options:
- A) Everything allowlisted (recommended — maximum cross-machine memory)
- B) Only artifacts (plans, designs, retros, learnings) — skip timelines and profile
- C) Decline — keep everything local

After the user answers, run (substituting the chosen value):

```bash
# 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 or B was chosen AND `~/.gstack/.git` doesn't exist, ask a follow-up:
"Set up the GBrain sync repo now? (runs `gstack-brain-init`)"
- A) Yes, run it now
- B) Show me the command, I'll run it myself

Do not block the skill. Emit the question, continue the skill workflow. The
next skill run picks up wherever this left off.

**At skill END (before the telemetry block),** run these bash commands to
catch artifact writes (design docs, plans, retros) that skipped the writer
shims, plus drain any still-pending queue entries:

```bash
"~/.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.

**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

**Tone:** direct, concrete, sharp, never corporate, never academic. Sound like a builder, not a consultant. Name the file, the function, the command. No filler, no throat-clearing.

**Writing rules:** No em dashes (use commas, periods, "..."). No AI vocabulary (delve, crucial, robust, comprehensive, nuanced, etc.). Short paragraphs. End with what to do.

The user always has context you don't. 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** — All steps completed successfully. Evidence provided for each claim.
- **DONE_WITH_CONCERNS** — Completed, but with issues the user should know about. List each concern.
- **BLOCKED** — Cannot proceed. State what is blocking and what was tried.
- **NEEDS_CONTEXT** — Missing information required to continue. State exactly what you need.

### Escalation

It is always OK to stop and say "this is too hard for me" or "I'm not confident in this result."

Bad work is worse than no work. You will not be penalized for escalating.
- If you have attempted a task 3 times without success, STOP and escalate.
- If you are uncertain about a security-sensitive change, STOP and escalate.
- If the scope of work exceeds what you can verify, STOP and escalate.

Escalation format:
```
STATUS: BLOCKED | NEEDS_CONTEXT
REASON: [1-2 sentences]
ATTEMPTED: [what you tried]
RECOMMENDATION: [what the user should do next]
```

## Operational Self-Improvement

Before completing, reflect on this session:
- Did any commands fail unexpectedly?
- Did you take a wrong approach and have to backtrack?
- Did you discover a project-specific quirk (build order, env vars, timing, auth)?
- Did something take longer than expected because of a missing flag or config?

If yes, log an operational learning for future sessions:

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

Replace SKILL_NAME with the current skill name. Only log genuine operational discoveries.
Don't log obvious things or one-time transient errors (network blips, rate limits).
A good test: would knowing this save 5+ minutes in a future session? If yes, log it.

## Telemetry (run last)

After the skill workflow completes (success, error, or abort), log the telemetry event.
Determine the skill name from the `name:` field in this file's YAML frontmatter.
Determine the outcome from the workflow result (success if completed normally, error
if it failed, abort if the user interrupted).

**PLAN MODE EXCEPTION — ALWAYS RUN:** This command writes telemetry to
`~/.gstack/analytics/` (user config directory, not project files). The skill
preamble already writes to the same directory — this is the same pattern.
Skipping this command loses session duration and outcome data.

Run this bash:

```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` with the actual skill name from frontmatter, `OUTCOME` with
success/error/abort, and `USED_BROWSE` with true/false based on whether `$B` was used.
If you cannot determine the outcome, use "unknown". The local JSONL always logs. The
remote binary only runs if telemetry is not off and the binary exists.

## Plan Status Footer

In plan mode, before ExitPlanMode: if the plan file lacks a `## GSTACK REVIEW REPORT`
section, run `~/.claude/skills/gstack/bin/gstack-review-read` and append a report.
With JSONL entries (before `---CONFIG---`), format the standard runs/status/findings
table. With `NO_REVIEWS` or empty, append a 5-row placeholder table (CEO/Codex/Eng/
Design/DX Review) with all zeros and verdict "NO REVIEWS YET — run `/autoplan`".
If a richer review report already exists, skip — review skills wrote it.

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

# browse: QA Testing & Dogfooding

Persistent headless Chromium. First call auto-starts (~3s), then ~100ms per command.
State persists between calls (cookies, tabs, login sessions).

## SETUP (run this check BEFORE any browse command)

```bash
_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:
   ```bash
   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
   ```

## Core QA Patterns

### 1. Verify a page loads correctly
```bash
$B goto https://yourapp.com
$B text                          # content loads?
$B console                       # JS errors?
$B network                       # failed requests?
$B is visible ".main-content"    # key elements present?
```

### 2. Test a user flow
```bash
$B goto https://app.com/login
$B snapshot -i                   # see all interactive elements
$B fill @e3 "user@test.com"
$B fill @e4 "password"
$B click @e5                     # submit
$B snapshot -D                   # diff: what changed after submit?
$B is visible ".dashboard"       # success state present?
```

### 3. Verify an action worked
```bash
$B snapshot                      # baseline
$B click @e3                     # do something
$B snapshot -D                   # unified diff shows exactly what changed
```

### 4. Visual evidence for bug reports
```bash
$B snapshot -i -a -o /tmp/annotated.png   # labeled screenshot
$B screenshot /tmp/bug.png                # plain screenshot
$B console                                # error log
```

### 5. Find all clickable elements (including non-ARIA)
```bash
$B snapshot -C                   # finds divs with cursor:pointer, onclick, tabindex
$B click @c1                     # interact with them
```

### 6. Assert element states
```bash
$B is visible ".modal"
$B is enabled "#submit-btn"
$B is disabled "#submit-btn"
$B is checked "#agree-checkbox"
$B is editable "#name-field"
$B is focused "#search-input"
$B js "document.body.textContent.includes('Success')"
```

### 7. Test responsive layouts
```bash
$B responsive /tmp/layout        # mobile + tablet + desktop screenshots
$B viewport 375x812              # or set specific viewport
$B screenshot /tmp/mobile.png
```

### 8. Test file uploads
```bash
$B upload "#file-input" /path/to/file.pdf
$B is visible ".upload-success"
```

### 9. Test dialogs
```bash
$B dialog-accept "yes"           # set up handler
$B click "#delete-button"        # trigger dialog
$B dialog                        # see what appeared
$B snapshot -D                   # verify deletion happened
```

### 10. Compare environments
```bash
$B diff https://staging.app.com https://prod.app.com
```

### 11. Show screenshots to the user
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.

### 12. Render local HTML (no HTTP server needed)
Two paths, pick the cleaner one:
```bash
# HTML file on disk → goto file:// (absolute, or cwd-relative)
$B goto file:///tmp/report.html
$B goto file://./docs/page.html        # cwd-relative
$B goto file://~/Documents/page.html   # home-relative

# HTML generated in memory → load-html reads the file into setContent
echo '<div class="tweet">hello</div>' > /tmp/tweet.html
$B load-html /tmp/tweet.html
```

`goto file://...` is usually cleaner (URL is saved in state, relative asset URLs resolve against the file's dir, scale changes replay naturally). `load-html` uses `page.setContent()` — URL stays `about:blank`, but the content survives `viewport --scale` via in-memory replay. Both are scoped to files under cwd or `$TMPDIR`.

### 13. Retina screenshots (deviceScaleFactor)
```bash
$B viewport 480x600 --scale 2       # 2x deviceScaleFactor
$B load-html /tmp/tweet.html        # or: $B goto file://./tweet.html
$B screenshot /tmp/out.png --selector .tweet-card
# → /tmp/out.png is 2x the pixel dimensions of the element
```
Scale must be 1-3 (gstack policy cap). Changing `--scale` recreates the browser context; refs from `snapshot` are invalidated (rerun `snapshot`), but `load-html` content is replayed automatically. Not supported in headed mode.

## Puppeteer → browse cheatsheet

Migrating from Puppeteer? Here's the 1:1 mapping for the core workflow:

| Puppeteer | browse |
|---|---|
| `await page.goto(url)` | `$B goto <url>` |
| `await page.setContent(html)` | `$B load-html <file>` (or `$B goto file://<abs>`) |
| `await page.setViewport({width, height})` | `$B viewport WxH` |
| `await page.setViewport({width, height, deviceScaleFactor: 2})` | `$B viewport WxH --scale 2` |
| `await (await page.$('.x')).screenshot({path})` | `$B screenshot <path> --selector .x` |
| `await page.screenshot({fullPage: true, path})` | `$B screenshot <path>` (full page default) |
| `await page.screenshot({clip: {x, y, w, h}, path})` | `$B screenshot <path> --clip x,y,w,h` |

Worked example (the tweet-renderer flow — Puppeteer → browse):

```bash
# Generate HTML in memory, render at 2x scale, screenshot the tweet card.
echo '<div class="tweet-card" style="width:400px;height:200px;background:#1da1f2;color:white;padding:20px">hello</div>' > /tmp/tweet.html
$B viewport 480x600 --scale 2
$B load-html /tmp/tweet.html
$B screenshot /tmp/out.png --selector .tweet-card
# /tmp/out.png is 800x400 px, crisp (2x deviceScaleFactor).
```

Aliases: typing `setcontent` or `set-content` routes to `load-html` automatically. Typing a typo (`load-htm`) returns `Did you mean 'load-html'?`.

## User Handoff

When you hit something you can't handle in headless mode (CAPTCHA, complex auth, multi-factor
login), hand off to the user:

```bash
# 1. Open a visible Chrome at the current page
$B handoff "Stuck on CAPTCHA at login page"

# 2. Tell the user what happened (via AskUserQuestion)
#    "I've opened Chrome at the login page. Please solve the CAPTCHA
#     and let me know when you're done."

# 3. When user says "done", re-snapshot and continue
$B resume
```

**When to use handoff:**
- CAPTCHAs or bot detection
- Multi-factor authentication (SMS, authenticator app)
- OAuth flows that require user interaction
- Complex interactions the AI can't handle after 3 attempts

The browser preserves all state (cookies, localStorage, tabs) across the handoff.
After `resume`, you get a fresh snapshot of wherever the user left off.

## Snapshot Flags

The snapshot is your primary tool for understanding and interacting with pages.
`$B` is the browse binary (resolved from `$_ROOT/.claude/skills/gstack/browse/dist/browse` or `~/.claude/skills/gstack/browse/dist/browse`).

**Syntax:** `$B snapshot [flags]`

```
-i        --interactive           Interactive elements only (buttons, links, inputs) with @e refs. Also auto-enables cursor-interactive scan (-C) to capture dropdowns and popovers.
-c        --compact               Compact (no empty structural nodes)
-d <N>    --depth                 Limit tree depth (0 = root only, default: unlimited)
-s <sel>  --selector              Scope to CSS selector
-D        --diff                  Unified diff against previous snapshot (first call stores baseline)
-a        --annotate              Annotated screenshot with red overlay boxes and ref labels
-o <path> --output                Output path for annotated screenshot (default: <temp>/browse-annotated.png)
-C        --cursor-interactive    Cursor-interactive elements (@c refs — divs with pointer, onclick). Auto-enabled when -i is used.
-H <json> --heatmap               Color-coded overlay screenshot from JSON map: '{"@e1":"green","@e3":"red"}'. Valid colors: green, yellow, red, blue, orange, gray.
```

All flags can be combined freely. `-o` only applies when `-a` is also used.
Example: `$B snapshot -i -a -C -o /tmp/annotated.png`

**Flag details:**
- `-d <N>`: depth 0 = root element only, 1 = root + direct children, etc. Default: unlimited. Works with all other flags including `-i`.
- `-s <sel>`: any valid CSS selector (`#main`, `.content`, `nav > ul`, `[data-testid="hero"]`). Scopes the tree to that subtree.
- `-D`: outputs a unified diff (lines prefixed with `+`/`-`/` `) comparing the current snapshot against the previous one. First call stores the baseline and returns the full tree. Baseline persists across navigations until the next `-D` call resets it.
- `-a`: saves an annotated screenshot (PNG) with red overlay boxes and @ref labels drawn on each interactive element. The screenshot is a separate output from the text tree — both are produced when `-a` is used.

**Ref numbering:** @e refs are assigned sequentially (@e1, @e2, ...) in tree order.
@c refs from `-C` are numbered separately (@c1, @c2, ...).

After snapshot, use @refs as selectors in any command:
```bash
$B click @e3       $B fill @e4 "value"     $B hover @e1
$B html @e2        $B css @e5 "color"      $B attrs @e6
$B click @c1       # cursor-interactive ref (from -C)
```

**Output format:** indented accessibility tree with @ref IDs, one element per line.
```
  @e1 [heading] "Welcome" [level=1]
  @e2 [textbox] "Email"
  @e3 [button] "Submit"
```

Refs are invalidated on navigation — run `snapshot` again after `goto`.

## CSS Inspector & Style Modification

### Inspect element CSS
```bash
$B inspect .header              # full CSS cascade for selector
$B inspect                      # latest picked element from sidebar
$B inspect --all                # include user-agent stylesheet rules
$B inspect --history            # show modification history
```

### Modify styles live
```bash
$B style .header background-color #1a1a1a   # modify CSS property
$B style --undo                              # revert last change
$B style --undo 2                            # revert specific change
```

### Clean screenshots
```bash
$B cleanup --all                 # remove ads, cookies, sticky, social
$B cleanup --ads --cookies       # selective cleanup
$B prettyscreenshot --cleanup --scroll-to ".pricing" --width 1440 ~/Desktop/hero.png
```
