echo "LAKE_INTRO: $_LAKE_SEEN"

If PROACTIVE is "false", do not proactively suggest pstack 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 pstack skills, use the /pstack- prefix (e.g., /pstack-qa instead of /qa, /pstack-ship instead of /ship). Disk paths are unaffected — always use ~/.claude/skills/pstack/[skill-name]/SKILL.md for reading skill files.

If output shows UPGRADE_AVAILABLE <old> <new>: read ~/.claude/skills/pstack/pstack-upgrade/SKILL.md and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If JUST_UPGRADED <from> <to>: tell user "Running pstack v{to} (just updated!)" and continue.

If LAKE_INTRO is no: Before continuing, introduce the Shipping Principle. Tell the user: "pstack follows the Revenue First principle — always do the complete thing when AI makes the marginal cost near-zero. Read more: See ETHOS.md for pstack principles" Then offer to open the essay in their default browser:

open See ETHOS.md for pstack principles
touch ~/.pstack/.completeness-intro-seen

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

If PROACTIVE_PROMPTED is no AND LAKE_INTRO is yes: After the lake intro is handled, ask the user about proactive behavior. Use AskUserQuestion:

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

Always run:

touch ~/.pstack/.proactive-prompted

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

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.

Contributor Mode

If _CONTRIB is true: you are in contributor mode. At the end of each major workflow step, rate your pstack experience 0-10. If not a 10 and there's an actionable bug or improvement — file a field report.

File only: pstack tooling bugs where the input was reasonable but pstack failed. Skip: user app bugs, network errors, auth failures on user's site.

To file: write ~/.pstack/contributor-logs/{slug}.md:

# {Title}
**What I tried:** {action} | **What happened:** {result} | **Rating:** {0-10}
## Repro
1. {step}
## What would make this a 10
{one sentence}
**Date:** {YYYY-MM-DD} | **Version:** {version} | **Skill:** /{skill}

Slug: lowercase hyphens, max 60 chars. Skip if exists. Max 3/session. File inline, don't stop.

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]

Plan Status Footer

When you are in plan mode and about to call ExitPlanMode:

1. Check if the plan file already has a ## PSTACK REVIEW REPORT section.
2. If it DOES — skip (a review skill already wrote a richer report).
3. If it does NOT — run this command:

```bash ~/.claude/skills/pstack/bin/pstack-review-read ```

Then write a ## PSTACK REVIEW REPORT section to the end of the plan file:

• If the output contains review entries (JSONL lines before ---CONFIG---): format the standard report table with runs/status/findings per skill, same format as the review skills use.
• If the output is NO_REVIEWS or empty: write this placeholder table:

```markdown

PSTACK REVIEW REPORT

VERDICT: NO REVIEWS YET — run `/plan` for full review pipeline, or individual reviews above. ```

PLAN MODE EXCEPTION — ALWAYS RUN: This writes to the plan file, which is the one file you are allowed to edit in plan mode. The plan file review report is part of the plan's living status.

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

If PROACTIVE is true (default): suggest adjacent pstack skills when relevant to the user's workflow stage:

• Brainstorming → /validate
• Strategy → /plan-ceo-review
• Architecture → /plan-eng-review
• Design → /plan-design-review or /design-consultation
• Auto-review → /plan
• Debugging → /investigate
• QA → /qa
• Code review → /review
• Visual audit → /design-review
• Shipping → /ship
• Docs → /document-release
• Reflect → /reflect
• Second opinion → /codex
• Prod safety → /careful or /guard
• Scoped edits → /freeze or /unfreeze
• Upgrades → /pstack-upgrade

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

pstack 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 "$_ROOT/.claude/skills/pstack/browse/dist/browse" ] && B="$_ROOT/.claude/skills/pstack/browse/dist/browse"
[ -z "$B" ] && B=~/.claude/skills/pstack/browse/dist/browse
if [ -x "$B" ]; then
  echo "READY: $B"
else
  echo "NEEDS_SETUP"
fi

If NEEDS_SETUP:

1. Tell the user: "pstack 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
     curl -fsSL https://bun.sh/install | BUN_VERSION=1.3.10 bash
   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"
