Recommended for

Automated summary

Generates a structured QA test plan for customer CSS deployments, focusing on predicted breakages, risk assessment, and manual test steps.

Strengths

  • Strict output format ensures consistent, actionable reports
  • Targeted identification of critical breakages with confidence levels
  • 300-line limit keeps reports concise and scoped
  • Incorporates Git history to detect recurring issues

Limitations

  • CSS-specific, does not cover other types of testing
  • Requires specific directory structure (src/customers/[customer]/custom.css)
  • Outputs only a report, no automated test execution
When to use it

Use this skill before deploying custom CSS stylesheets for a client to get a quick risk analysis and manual test plan.

When not to use it

Do not use it for general non-CSS testing, or when you need full automated test suites rather than a manual test plan.

How this analysis is made

Examples

New customer CSS deployment
Generate a QA test plan for the CSS deployment for customer AcmeCorp. Analyze potential conflicts and provide a risk assessment.
CSS conflict analysis
Analyze CSS for CustomerX and create a manual test plan to ensure no visual regressions after their custom styles are applied.
Pre-deployment CSS audit
I need a pre-deployment risk assessment for the new custom CSS for Client Y. Identify predicted breakages and test sessions.

⚠️ OUTPUT RULES - READ FIRST

Generate EXACTLY these 3 sections in this order:

  1. Predicted Breakages (3-7 issues max)
  2. Risk Assessment (single table)
  3. Manual Test Plan (test sessions with checkboxes)

Total length: 300 lines maximum

All other sections are FORBIDDEN unless explicitly valuable for THIS deployment.


When to Use This Skill

  • User mentions: "QA test plan", "CSS conflicts", "analyze CSS for [customer]"
  • Customer CSS deployment scenarios
  • Pre-deployment risk assessment

Analysis Workflow

Step 1: Read Customer CSS

  • Location: src/customers/[customer]/custom.css
  • Flag: Global selectors, !important, element selectors

Step 2: Read Application Styles

  • Core: src/app/@core/components/
  • Theme: src/app/@theme/
  • Pages: src/app/pages/

Step 3: Detect Conflicts

  • Compare selectors
  • Check specificity + !important
  • Predict cascade issues

Step 4: Check Git History

  • Search: "CSS", "style", "[customer name]"
  • Find patterns from past bugs

Step 5: Generate Report

Follow exact format below.


REQUIRED OUTPUT FORMAT

File: risk reports/qa_test_report_[customer].md

Structure (STRICT):

# QA Test Report - [Customer] CSS Deployment

## 🔍 Predicted Breakages

### Issue #1: [Short Title]
**Severity:** 🔴 CRITICAL
**Priority:** P1
**Confidence:** 95%

**What Breaks:**
- Component: [name]
- Expected: [normal behavior]
- After deploy: [broken behavior]

**Root Cause:**
```css
/* problematic CSS */
```

**Impact:**
- User: [how affected]
- Business: [consequences]

**Where to Test:**
- Page 1
- Page 2

**Test Steps:**
1. Navigate to [page]
2. Check [element]
3. Expected: [result]
4. If broken: [what happens]

[Repeat for issues #2-7 max]

## 📊 Risk Assessment

| Issue | Severity | Priority | Confidence | Impact |
|-------|----------|----------|------------|--------|
| [Issue 1] | 🔴 CRITICAL | P1 | 95% | [desc] |
| [Issue 2] | 🟡 HIGH | P2 | 90% | [desc] |

**Severity Key:**
- 🔴 CRITICAL: App unusable, blocks deployment
- 🟡 HIGH: Major visual/functional issue
- 🟢 MEDIUM: Minor issue, workarounds exist
- ⚪ LOW: Negligible impact

---

## 📋 Manual Test Plan

### Test Session 1: Critical Issues (XX min)

**Setup:**
- Browser: Chrome (latest)
- Environment: Test

#### Test 1.1: [Test Name]
- [ ] Step 1: [action]
- [ ] Step 2: [action]
- [ ] Expected: [result]
- [ ] If broken: [report what]
- [ ] Stop condition: Yes/No

[Repeat for sessions 2-3 max]

---
**END OF REPORT**

Optional Sections (Use Sparingly)

Include ONLY if critically valuable:

  • Executive Summary (2-3 lines) - Deploy yes/no at top
  • Stop Conditions - When to halt testing
  • Time Estimates - Per session only

Do NOT add:

  • Screenshots checklists
  • Bug templates
  • Historical context
  • Reference info
  • Success criteria
  • Contact info
  • Execution logs
  • ASCII diagrams

Severity Guidelines

Confidence:

  • 100%: Same selector + !important
  • 90-95%: Global selector
  • 80-90%: Similar selectors
  • 70-80%: Potential conflict
  • <70%: Low risk

Priority:

  • P1: Blocks deployment
  • P2: Test before deploy
  • P3: Document only

Best Practices

  1. Check git history for patterns
  2. Focus on: button, input, div, element selectors
  3. Any !important = red flag
  4. Global selectors = dangerous
  5. Keep report under 300 lines

Output Checklist

Before saving, verify:

  • [ ] Only 3 main sections
  • [ ] 3-7 issues max
  • [ ] Under 300 lines
  • [ ] No forbidden sections
  • [ ] Saved to: risk reports/qa_test_report_[customer].md

Example Output Length

# QA Test Report - CustomerB CSS

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/css-qa-analysis-mryiqfu7/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/css-qa-analysis-mryiqfu7' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/css-qa-analysis-mryiqfu7/download' --output '.skill-downloads/css-qa-analysis-mryiqfu7/SKILL.md.part' && mv '.skill-downloads/css-qa-analysis-mryiqfu7/SKILL.md.part' '.skill-downloads/css-qa-analysis-mryiqfu7/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

Claude Code
test -f '.skill-downloads/css-qa-analysis-mryiqfu7/SKILL.md' && test -s '.skill-downloads/css-qa-analysis-mryiqfu7/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/qa-css-analysis' && cp -R '.skill-downloads/css-qa-analysis-mryiqfu7' '.claude/skills/qa-css-analysis'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/css-qa-analysis-mryiqfu7'

openskills read 'css-qa-analysis-mryiqfu7'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/css-qa-analysis-mryiqfu7/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
