QA Phase Skill

Execute QA phase of the PDCA cycle. Automatically runs L1-L5 tests with Chrome MCP integration.

Arguments

Argument	Description	Example
[feature]	Target feature to test	/qa-phase user-auth

Workflow

1. Context: Read design doc and Check phase analysis
2. Plan: Generate test plan (L1-L5 items with priorities)
3. Generate: Create test code files
4. Execute: Run L1-L5 tests (L3-L5 require Chrome MCP)
5. Report: Generate QA report to docs/05-qa/{feature}.qa-report.md

PRE-SCAN: Pre-Release Quality Check

Before running L1 tests, execute the automated quality scanners to catch structural issues early.

Steps

1. Run scripts/qa/pre-release-check.sh via Bash
2. Parse the output for CRITICAL / WARNING / INFO counts
3. If CRITICAL issues found:
   • Report all CRITICAL issues with file paths and suggested fixes
   • Recommend fixing CRITICAL issues before proceeding with L1-L5 tests
   • Ask user whether to continue or abort QA phase
4. If only WARNING/INFO issues (no CRITICAL):
   • Include scanner results in the QA report under "Pre-Release Scan" section
   • Continue to L1 test planning

Scanner Coverage

Scanner	Detects	Severity
dead-code	Stale require/import, unused exports	CRITICAL / WARNING
config-audit	Unreferenced config keys, hardcoded values, missing paths	CRITICAL / WARNING / INFO
completeness	Missing agents, long descriptions, missing effort	CRITICAL / WARNING / INFO
shell-escape	Bare $N in awk, unescaped backticks, unsafe heredocs	CRITICAL / WARNING

QA Report Integration

When scanner results are available, include them in the QA report:

## Pre-Release Scan Results

- **Scanner**: dead-code — 0 CRITICAL, 1 WARNING, 0 INFO
- **Scanner**: config-audit — 0 CRITICAL, 0 WARNING, 2 INFO
- **Scanner**: completeness — 0 CRITICAL, 0 WARNING, 1 INFO
- **Scanner**: shell-escape — 0 CRITICAL, 0 WARNING, 0 INFO

**Overall**: PASS (0 CRITICAL issues)

Test Levels

Level	Type	Tool	Chrome Required
L1	Unit Test	Node.js / Jest / Vitest	No
L2	API Test	fetch / curl	No
L3	E2E Test	Chrome MCP	Yes
L4	UX Flow Test	Chrome MCP	Yes

Fallback

Chrome MCP unavailable:

• L1 + L2 only
• QA report notes "L3-L5 skipped"
• QA pass/fail based on L1+L2 results only
