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 no variant is callable, the skill is BLOCKED. Stop and report BLOCKED. AskUserQuestion unavailable per the AskUserQuestion Format rule. 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 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 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.

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

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-"$_SESSION_ID" 2>/dev/null || true
# Session timeline: record skill completion (local-only, never sent anywhere)
~/.claude/skills/gstack/bin/gstack-timeline-log '{"skill":"SKILL_NAME","event":"completed","branch":"'$(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

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.

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.

Routing rules. When you see these patterns, INVOKE the skill via the Skill tool:

• User describes a new idea, asks "is this worth building", brainstorms, pitches a concept → invoke /office-hours
• User asks about strategy, scope, ambition, "think bigger", "what should we build" → invoke /plan-ceo-review
• User asks to review architecture, lock in the plan, "does this design make sense" → invoke /plan-eng-review
• User asks about design system, brand, visual identity, "how should this look" → invoke /design-consultation
• User asks to review design of a plan → invoke /plan-design-review
• User asks about developer experience of a plan, API/CLI/SDK design → invoke /plan-devex-review
• User wants all reviews done automatically, "review everything" → invoke /autoplan
• User reports a bug, error, broken behavior, "why is this broken", "this doesn't work", "wtf", "something's wrong" → invoke /investigate
• User asks to test the site, find bugs, QA, "does this work", "check the deploy" → invoke /qa
• User asks to just report bugs without fixing → invoke /qa-only
• User asks to review code, check the diff, pre-landing review, "look at my changes" → invoke /review
• User asks about visual polish, design audit of a live site, "this looks off" → invoke /design-review
• User asks to audit the live developer experience, time-to-hello-world → invoke /devex-review
• User asks to ship, deploy, push, create a PR, "let's land this", "send it" → invoke /ship
• User asks to merge + deploy + verify as one flow → invoke /land-and-deploy
• User asks to configure deployment for the project → invoke /setup-deploy
• User asks to monitor prod after shipping, post-deploy checks → invoke /canary
• User asks to update docs after shipping → invoke /document-release
• User asks to write docs from scratch, generate documentation, "document this feature/module" → invoke /document-generate
• User asks for a weekly retro, what did we ship, "how'd we do" → invoke /retro
• User asks for a second opinion, codex review → invoke /codex
• User asks for safety mode, careful mode → invoke /careful or /guard
• User asks to restrict edits to a directory → invoke /freeze or /unfreeze
• User asks to upgrade gstack → invoke /gstack-upgrade
• User asks to save progress, checkpoint, "save my work" → invoke /context-save
• User asks to resume, restore, "where was I" → invoke /context-restore
• User asks about security, OWASP, vulnerabilities, "is this secure" → invoke /cso
• User asks to make a PDF, document, publication → invoke /make-pdf
• User asks to launch a real browser for QA, "open the browser" → invoke /open-gstack-browser
• User asks to import cookies for authenticated testing → invoke /setup-browser-cookies
• User asks about page speed, performance regression, benchmarks → invoke /benchmark
• User asks what gstack has learned, "show learnings" → invoke /learn
• User asks to tune question sensitivity, "stop asking me that" → invoke /plan-tune
• User asks for code quality dashboard, "health check" → invoke /health

When in doubt, invoke the skill. A false positive (invoking a skill that wasn't needed) is cheaper than a false negative (answering ad-hoc when a structured workflow exists). The skill provides multi-step workflows, checklists, and quality gates that always produce better results than an ad-hoc answer. If no skill matches, answer directly as usual.

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

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
   

IMPORTANT

• Use the compiled binary via Bash: $B <command>
• 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.

QA Workflows

Credential safety: Use environment variables for test credentials. Set them before running: export TEST_EMAIL="..." TEST_PASSWORD="..."

Test a user flow (login, signup, checkout, etc.)

# 1. Go to the page
$B goto https://app.example.com/login

# 2. See what's interactive
$B snapshot -i

# 3. Fill the form using refs
$B fill @e3 "$TEST_EMAIL"
$B fill @e4 "$TEST_PASSWORD"
$B click @e5

# 4. Verify it worked
$B snapshot -D              # diff shows what changed after clicking
$B is visible ".dashboard"  # assert the dashboard appeared
$B screenshot /tmp/after-login.png

Verify a deployment / check prod

$B goto https://yourapp.com
$B text                          # read the page, does it load?
$B console                       # any JS errors?
$B network                       # any failed requests?
$B js "document.title"           # correct title?
$B is visible ".hero-section"    # key elements present?
$B screenshot /tmp/prod-check.png

Dogfood a feature end-to-end

# Navigate to the feature
$B goto https://app.example.com/new-feature

# Take annotated screenshot, shows every interactive element with labels
$B snapshot -i -a -o /tmp/feature-annotated.png

# Find ALL clickable things (including divs with cursor:pointer)
$B snapshot -C

# Walk through the flow
$B snapshot -i          # baseline
$B click @e3            # interact
$B snapshot -D          # what changed? (unified diff)

# Check element states
$B is visible ".success-toast"
$B is enabled "#next-step-btn"
$B is checked "#agree-checkbox"

# Check console for errors after interactions
$B console

Test responsive layouts

# Quick: 3 screenshots at mobile/tablet/desktop
$B goto https://yourapp.com
$B responsive /tmp/layout

# Manual: specific viewport
$B viewport 375x812     # iPhone
$B screenshot /tmp/mobile.png
$B viewport 1440x900    # Desktop
$B screenshot /tmp/desktop.png

# Element screenshot (crop to specific element)
$B screenshot "#hero-banner" /tmp/hero.png
$B snapshot -i
$B screenshot @e3 /tmp/button.png

# Region crop
$B screenshot --clip 0,0,800,600 /tmp/above-fold.png

# Viewport only (no scroll)
$B screenshot --viewport /tmp/viewport.png

Test file upload

$B goto https://app.example.com/upload
$B snapshot -i
$B upload @e3 /path/to/test-file.pdf
$B is visible ".upload-success"
$B screenshot /tmp/upload-result.png

Test forms with validation

$B goto https://app.example.com/form
$B snapshot -i

# Submit empty. Check validation errors appear
$B click @e10                        # submit button
$B snapshot -D                       # diff shows error messages appeared
$B is visible ".error-message"

# Fill and resubmit
$B fill @e3 "valid input"
$B click @e10
$B snapshot -D                       # diff shows errors gone, success state

Test dialogs (delete confirmations, prompts)

# Set up dialog handling BEFORE triggering
$B dialog-accept              # will auto-accept next alert/confirm
$B click "#delete-button"     # triggers confirmation dialog
$B dialog                     # see what dialog appeared
$B snapshot -D                # verify the item was deleted

# For prompts that need input
$B dialog-accept "my answer"  # accept with text
$B click "#rename-button"     # triggers prompt

Test authenticated pages (import real browser cookies)

# Import cookies from your real browser (opens interactive picker)
$B cookie-import-browser

# Or import a specific domain directly
$B cookie-import-browser comet --domain .github.com

# Now test authenticated pages
$B goto https://github.com/settings/profile
$B snapshot -i
$B screenshot /tmp/github-profile.png

Cookie safety: cookie-import-browser transfers real session data. Only import cookies from browsers you control.

Compare two pages / environments

$B diff https://staging.app.com https://prod.app.com

Multi-step chain (efficient for long flows)

echo '[
  ["goto","https://app.example.com"],
  ["snapshot","-i"],
  ["fill","@e3","$TEST_EMAIL"],
  ["fill","@e4","$TEST_PASSWORD"],
  ["click","@e5"],
  ["snapshot","-D"],
  ["screenshot","/tmp/result.png"]
]' | $B chain

Quick Assertion Patterns

# Element exists and is visible
$B is visible ".modal"

# Button is enabled/disabled
$B is enabled "#submit-btn"
$B is disabled "#submit-btn"

# Checkbox state
$B is checked "#agree"

# Input is editable
$B is editable "#name-field"

# Element has focus
$B is focused "#search-input"

# Page contains text
$B js "document.body.textContent.includes('Success')"

# Element count
$B js "document.querySelectorAll('.list-item').length"

# Specific attribute value
$B attrs "#logo"    # returns all attributes as JSON

# CSS property
$B css ".button" "background-color"

Snapshot System

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:

$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.

Tips

1. Navigate once, query many times. goto loads the page; then text, js, screenshot all hit the loaded page instantly.
2. Use snapshot -i first. See all interactive elements, then click/fill by ref. No CSS selector guessing.
3. Use snapshot -D to verify. Baseline → action → diff. See exactly what changed.
4. Use is for assertions. is visible .modal is faster and more reliable than parsing page text.
5. Use snapshot -a for evidence. Annotated screenshots are great for bug reports.
6. Use snapshot -C for tricky UIs. Finds clickable divs that the accessibility tree misses.
7. Check console after actions. Catch JS errors that don't surface visually.
8. Use chain for long flows. Single command, no per-step CLI overhead.
