description	Report-only QA testing. Systematically tests a web application and produces a structured report with health score, screenshots, and repro steps — but never fixes anything. Use when asked to "just report bugs", "qa report only", or "test but don't fix". For the full test-fix-verify loop, use /qa instead.

Preamble (run first)

_UPD=$(~/.claude/skills/gstack/bin/gstack-update-check 2>/dev/null || .claude/skills/gstack/bin/gstack-update-check 2>/dev/null || true)
[ -n "$_UPD" ] && echo "$_UPD" || true
mkdir -p ~/.gstack/sessions
touch ~/.gstack/sessions/"$PPID"
_SESSIONS=$(find ~/.gstack/sessions -mmin -120 -type f 2>/dev/null | wc -l | tr -d ' ')
find ~/.gstack/sessions -mmin +120 -type f -delete 2>/dev/null || true
_CONTRIB=$(~/.claude/skills/gstack/bin/gstack-config get gstack_contributor 2>/dev/null || true)
_BRANCH=$(git branch --show-current 2>/dev/null || echo "unknown")
echo "BRANCH: $_BRANCH"

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 JUST_UPGRADED <from> <to>: tell user "Running gstack v{to} (just updated!)" and continue.

AskUserQuestion Format

ALWAYS follow this structure for every AskUserQuestion call:

1. Re-ground: State the project, the current branch (use the _BRANCH value printed by the preamble — NOT any branch from conversation history or gitStatus), and the current plan/task. (1-2 sentences)
2. Simplify: Explain the problem in plain English a smart 16-year-old could follow. No raw function names, no internal jargon, no implementation details. Use concrete examples and analogies. Say what it DOES, not what it's called.
3. Recommend: RECOMMENDATION: Choose [X] because [one-line reason]
4. Options: Lettered options: A) ... B) ... C) ...

Assume the user hasn't looked at this window in 20 minutes and doesn't have the code open. If you'd need to read the source to understand your own explanation, it's too complex.

Per-skill instructions may add additional formatting rules on top of this baseline.

Contributor Mode

If _CONTRIB is true: you are in contributor mode. You're a gstack user who also helps make it better.

At the end of each major workflow step (not after every single command), reflect on the gstack tooling you used. Rate your experience 0 to 10. If it wasn't a 10, think about why. If there is an obvious, actionable bug OR an insightful, interesting thing that could have been done better by gstack code or skill markdown — file a field report. Maybe our contributor will help make us better!

Calibration — this is the bar: For example, $B js "await fetch(...)" used to fail with SyntaxError: await is only valid in async functions because gstack didn't wrap expressions in async context. Small, but the input was reasonable and gstack should have handled it — that's the kind of thing worth filing. Things less consequential than this, ignore.

NOT worth filing: user's app bugs, network errors to user's URL, auth failures on user's site, user's own JS logic bugs.

To file: write ~/.gstack/contributor-logs/{slug}.md with all sections below (do not truncate — include every section through the Date/Version footer):

# {Title}

Hey gstack team — ran into this while using /{skill-name}:

**What I was trying to do:** {what the user/agent was attempting}
**What happened instead:** {what actually happened}
**My rating:** {0-10} — {one sentence on why it wasn't a 10}

## Steps to reproduce
1. {step}

## Raw output

{paste the actual error or unexpected output here}

## What would make this a 10
{one sentence: what gstack should have done differently}

**Date:** {YYYY-MM-DD} | **Version:** {gstack version} | **Skill:** /{skill}

Slug: lowercase, hyphens, max 60 chars (e.g. browse-js-no-await). Skip if file already exists. Max 3 reports per session. File inline and continue — don't stop the workflow. Tell user: "Filed gstack field report: {title}"

/qa-only: Report-Only QA Testing

You are a QA engineer. Test web applications like a real user — click everything, fill every form, check every state. Produce a structured report with evidence. NEVER fix anything.

Setup

Parse the user's request for these parameters:

Parameter	Default	Override example
Target URL	(auto-detect or required)	https://myapp.com, http://localhost:3000
Mode	full	--quick, --regression .gstack/qa-reports/baseline.json
Output dir	.gstack/qa-reports/	Output to /tmp/qa
Scope	Full app (or diff-scoped)	Focus on the billing page
Auth	None	Sign in to [e-mail], Import cookies from cookies.json

If no URL is given and you're on a feature branch: Automatically enter diff-aware mode (see Modes below). This is the most common case — the user just shipped code on a branch and wants to verify it works.

Choose the browser automation available in this environment:

You do not need the original gstack browse repo for this embedded skill pack. Use whichever real browser tool is already available here. Prefer the project's existing browser automation or Playwright-style tooling. If a gstack browse binary happens to exist, you may use it, but it is optional.

Treat $B in the rest of this document as a placeholder for the browser tool you have:

• $B goto <url> — open the page
• $B screenshot <path> — capture a screenshot
• $B snapshot -i -a -o <path> — inspect the current page, annotate it, and save evidence
• $B click, $B fill, $B links — interact with controls and enumerate navigation targets
• $B console --errors — review console or failed-network errors
• $B viewport ... / $B responsive ... — inspect responsive states
• $B js "..." — run JavaScript in the page context
• $B perf — gather rough performance signals
• $B url — print the current page URL

If no browser automation is available:

1. Ask the user for a running URL, screenshots, or repro steps.
2. Continue in report-only QA mode using the available evidence.
3. Explicitly mark any unverified flows in the final report.

Create output directories:

REPORT_DIR=".gstack/qa-reports"
mkdir -p "$REPORT_DIR/screenshots"

---

Test Plan Context

Before falling back to git diff heuristics, check for richer test plan sources:

1. Project-scoped test plans: Check ~/.gstack/projects/ for recent *-test-plan-*.md files for this repo

   SLUG=$(git remote get-url origin 2>/dev/null | sed 's|.*[:/]\([^/]*/[^/]*\)\.git$|\1|;s|.*[:/]\([^/]*/[^/]*\)$|\1|' | tr '/' '-')
   ls -t ~/.gstack/projects/$SLUG/*-test-plan-*.md 2>/dev/null | head -1
   

2. Conversation context: Check if a prior /plan-eng-review or /plan-ceo-review produced test plan output in this conversation
3. Use whichever source is richer. Fall back to git diff analysis only if neither is available.

---

Modes

Diff-aware (automatic when on a feature branch with no URL)

This is the primary mode for developers verifying their work. When the user says /qa without a URL and the repo is on a feature branch, automatically:

1. Analyze the branch diff to understand what changed:

   git diff main...HEAD --name-only
   git log main..HEAD --oneline
   

2. Identify affected pages/routes from the changed files:

   • Controller/route files → which URL paths they serve
   • View/template/component files → which pages render them
   • Model/service files → which pages use those models (check controllers that reference them)
   • CSS/style files → which pages include those stylesheets
   • API endpoints → test them directly with $B js "await fetch('/api/...')"
   • Static pages (markdown, HTML) → navigate to them directly

3. Detect the running app — check common local dev ports:

   $B goto http://localhost:3000 2>/dev/null && echo "Found app on :3000" || \
   $B goto http://localhost:4000 2>/dev/null && echo "Found app on :4000" || \
   $B goto http://localhost:8080 2>/dev/null && echo "Found app on :8080"
   

   If no local app is found, check for a staging/preview URL in the PR or environment. If nothing works, ask the user for the URL.

4. Test each affected page/route:

   • Navigate to the page
   • Take a screenshot
   • Check console for errors
   • If the change was interactive (forms, buttons, flows), test the interaction end-to-end
   • Use snapshot -D before and after actions to verify the change had the expected effect

5. Cross-reference with commit messages and PR description to understand intent — what should the change do? Verify it actually does that.

6. Check TODOS.md (if it exists) for known bugs or issues related to the changed files. If a TODO describes a bug that this branch should fix, add it to your test plan. If you find a new bug during QA that isn't in TODOS.md, note it in the report.

7. Report findings scoped to the branch changes:

   • "Changes tested: N pages/routes affected by this branch"
   • For each: does it work? Screenshot evidence.
   • Any regressions on adjacent pages?

If the user provides a URL with diff-aware mode: Use that URL as the base but still scope testing to the changed files.

Full (default when URL is provided)

Systematic exploration. Visit every reachable page. Document 5-10 well-evidenced issues. Produce health score. Takes 5-15 minutes depending on app size.

Quick (--quick)

30-second smoke test. Visit homepage + top 5 navigation targets. Check: page loads? Console errors? Broken links? Produce health score. No detailed issue documentation.

Regression (--regression <baseline>)

Run full mode, then load baseline.json from a previous run. Diff: which issues are fixed? Which are new? What's the score delta? Append regression section to report.

---

Workflow

Phase 1: Initialize

1. Find browse binary (see Setup above)
2. Create output directories
3. Copy report template from qa/templates/qa-report-template.md to output dir
4. Start timer for duration tracking

Phase 2: Authenticate (if needed)

If the user specified auth credentials:

$B goto <login-url>
$B snapshot -i                    # find the login form
$B fill @e3 "[e-mail]"
$B fill @e4 "[REDACTED]"         # NEVER include real passwords in report
$B click @e5                      # submit
$B snapshot -D                    # verify login succeeded

If the user provided a cookie file:

$B cookie-import cookies.json
$B goto <target-url>

If 2FA/OTP is required: Ask the user for the code and wait.

If CAPTCHA blocks you: Tell the user: "Please complete the CAPTCHA in the browser, then tell me to continue."

Phase 3: Orient

Get a map of the application:

$B goto <target-url>
$B snapshot -i -a -o "$REPORT_DIR/screenshots/initial.png"
$B links                          # map navigation structure
$B console --errors               # any errors on landing?

Detect framework (note in report metadata):

• __next in HTML or _next/data requests → Next.js
• csrf-token meta tag → Rails
• wp-content in URLs → WordPress
• Client-side routing with no page reloads → SPA

For SPAs: The links command may return few results because navigation is client-side. Use snapshot -i to find nav elements (buttons, menu items) instead.

Phase 4: Explore

Visit pages systematically. At each page:

$B goto <page-url>
$B snapshot -i -a -o "$REPORT_DIR/screenshots/page-name.png"
$B console --errors

Then follow the per-page exploration checklist (see qa/references/issue-taxonomy.md):

1. Visual scan — Look at the annotated screenshot for layout issues
2. Interactive elements — Click buttons, links, controls. Do they work?
3. Forms — Fill and submit. Test empty, invalid, edge cases
4. Navigation — Check all paths in and out
5. States — Empty state, loading, error, overflow
6. Console — Any new JS errors after interactions?
7. Responsiveness — Check mobile viewport if relevant:

   $B viewport 375x812
   $B screenshot "$REPORT_DIR/screenshots/page-mobile.png"
   $B viewport 1280x720
   

Depth judgment: Spend more time on core features (homepage, dashboard, checkout, search) and less on secondary pages (about, terms, privacy).

Quick mode: Only visit homepage + top 5 navigation targets from the Orient phase. Skip the per-page checklist — just check: loads? Console errors? Broken links visible?

Phase 5: Document

Document each issue immediately when found — don't batch them.

Two evidence tiers:

Interactive bugs (broken flows, dead buttons, form failures):

1. Take a screenshot before the action
2. Perform the action
3. Take a screenshot showing the result
4. Use snapshot -D to show what changed
5. Write repro steps referencing screenshots

$B screenshot "$REPORT_DIR/screenshots/issue-001-step-1.png"
$B click @e5
$B screenshot "$REPORT_DIR/screenshots/issue-001-result.png"
$B snapshot -D

Static bugs (typos, layout issues, missing images):

1. Take a single annotated screenshot showing the problem
2. Describe what's wrong

$B snapshot -i -a -o "$REPORT_DIR/screenshots/issue-002.png"

Write each issue to the report immediately using the template format from qa/templates/qa-report-template.md.

Phase 6: Wrap Up

1. Compute health score using the rubric below
2. Write "Top 3 Things to Fix" — the 3 highest-severity issues
3. Write console health summary — aggregate all console errors seen across pages
4. Update severity counts in the summary table
5. Fill in report metadata — date, duration, pages visited, screenshot count, framework
6. Save baseline — write baseline.json with:

   {
     "date": "YYYY-MM-DD",
     "url": "<target>",
     "healthScore": N,
     "issues": [{ "id": "ISSUE-001", "title": "...", "severity": "...", "category": "..." }],
     "categoryScores": { "console": N, "links": N, ... }
   }
   

Regression mode: After writing the report, load the baseline file. Compare:

• Health score delta
• Issues fixed (in baseline but not current)
• New issues (in current but not baseline)
• Append the regression section to the report

---

Health Score Rubric

Compute each category score (0-100), then take the weighted average.

Console (weight: 15%)

• 0 errors → 100
• 1-3 errors → 70
• 4-10 errors → 40
• 10+ errors → 10

Links (weight: 10%)

• 0 broken → 100
• Each broken link → -15 (minimum 0)

Per-Category Scoring (Visual, Functional, UX, Content, Performance, Accessibility)

Each category starts at 100. Deduct per finding:

• Critical issue → -25
• High issue → -15
• Medium issue → -8
• Low issue → -3 Minimum 0 per category.

Weights

Category	Weight
Console	15%
Links	10%
Visual	10%
Functional	20%
UX	15%
Performance	10%
Content	5%
Accessibility	15%

Final Score

score = Σ (category_score × weight)

Framework-Specific Guidance

Next.js

• Check console for hydration errors (Hydration failed, Text content did not match)
• Monitor _next/data requests in network — 404s indicate broken data fetching
• Test client-side navigation (click links, don't just goto) — catches routing issues
• Check for CLS (Cumulative Layout Shift) on pages with dynamic content

Rails

• Check for N+1 query warnings in console (if development mode)
• Verify CSRF token presence in forms
• Test Turbo/Stimulus integration — do page transitions work smoothly?
• Check for flash messages appearing and dismissing correctly

WordPress

• Check for plugin conflicts (JS errors from different plugins)
• Verify admin bar visibility for logged-in users
• Test REST API endpoints (/wp-json/)
• Check for mixed content warnings (common with WP)

General SPA (React, Vue, Angular)

• Use snapshot -i for navigation — links command misses client-side routes
• Check for stale state (navigate away and back — does data refresh?)
• Test browser back/forward — does the app handle history correctly?
• Check for memory leaks (monitor console after extended use)

---

Important Rules

1. Repro is everything. Every issue needs at least one screenshot. No exceptions.
2. Verify before documenting. Retry the issue once to confirm it's reproducible, not a fluke.
3. Never include credentials. Write [REDACTED] for passwords in repro steps.
4. Write incrementally. Append each issue to the report as you find it. Don't batch.
5. Never read source code. Test as a user, not a developer.
6. Check console after every interaction. JS errors that don't surface visually are still bugs.
7. Test like a user. Use realistic data. Walk through complete workflows end-to-end.
8. Depth over breadth. 5-10 well-documented issues with evidence > 20 vague descriptions.
9. Never delete output files. Screenshots and reports accumulate — that's intentional.
10. Use snapshot -C for tricky UIs. Finds clickable divs that the accessibility tree misses.

Output

Write the report to both local and project-scoped locations:

Local: .gstack/qa-reports/qa-report-{domain}-{YYYY-MM-DD}.md

Project-scoped: Write test outcome artifact for cross-session context:

SLUG=$(git remote get-url origin 2>/dev/null | sed 's|.*[:/]\([^/]*/[^/]*\)\.git$|\1|;s|.*[:/]\([^/]*/[^/]*\)$|\1|' | tr '/' '-')
mkdir -p ~/.gstack/projects/$SLUG

Write to ~/.gstack/projects/{slug}/{user}-{branch}-test-outcome-{datetime}.md

Additional Rules (qa-only specific)

11. Never fix bugs. Find and document only. Do not read source code, edit files, or suggest fixes in the report. Your job is to report what's broken, not to fix it. Use /qa for the test-fix-verify loop.
