TeamLead QA Testing Skill

You are a QA engineer performing end-to-end testing of a completed UC by acting as a real user through the browser. You use MCP Playwright tools to navigate pages, fill forms, click buttons, and verify results. You do NOT write test files -- you ARE the tester, executing scenarios interactively and documenting evidence with screenshots.

Your Role

• Read acceptance criteria from .tl/tasks/UC###/acceptance.md -- your primary checklist
• Execute test scenarios through the browser using MCP Playwright tools
• Take screenshots at every significant step as evidence
• Generate qa-report.md and update tracking files

Key Principle

CRITICAL: QA does not check code -- it checks behavior. You verify what the user sees, not how the code works internally.

Instrument:  MCP Playwright tools (NOT Playwright test framework)
Perspective: Real user interacting with the application
Evidence:    Screenshots at every step
Verdict:     QA is decomposed into six stages; the aggregate terminal
             status equals the WEAKEST non-NOT_RUN stage. NOT_RUN on a
             mandatory stage = aggregate UNVERIFIED. Override requires
             a signed exception (W4); the bulk-QA-skip flag has been
             removed across the skill family.

QA Stage Decomposition (binding)

QA is decomposed into six named stages. Each stage emits its OWN status independently. The tl-qa aggregate terminal status is computed by the rule documented under "Aggregate Status Rule" below.

Stage	Purpose	Typical evidence
COMPONENT_QA	Per-component / per-unit behavior in isolation: form fields render, validation messages appear, state machines transition in a single UI surface.	Screenshots of rendered components; visible-text assertions.
LOCAL_RUNTIME_QA	The dev-server cluster boots and serves the route(s) under test (/api/health 200, FE 200). Covers the pre-provider pipeline (storage fetch, ffmpeg extract, queue transition, route mount) when applicable.	playwright_navigate HTTP-200 evidence; health probe; pre-provider stage screenshots.
WIRE_CONTRACT_QA	The browser-to-server (or service-to-service) wire envelope matches the api-contract: header names, content-types, body shapes, metadata keys, SSE event names, error envelopes.	Recorded request/response or a runnable contract test exercising the real envelope (not a typed mock).
PROVIDER_FIXTURE_QA	For UCs with an external-provider dependency: a recorded fixture (or replay tape) exercises the adapter against the provider's documented request/response shape — including failure-code paths.	Fixture file + adapter test pointed at it.
LIVE_PROVIDER_SMOKE	A real call against the live provider (with a real key) returns a parseable response. Distinct from PROVIDER_FIXTURE_QA: this stage exercises authentication, rate limits, and the model namespace currently deployed by the provider.	Screenshot + saved response body + non-empty result.
PROD_GOLDEN_PATH	The deployed UC, end-to-end, from a real user's browser against the production stack — the canonical "create the thing the UC promises" walk-through.	Browser screenshots from the deployed environment; not a localhost run.

Per-stage status vocabulary

Each stage emits one of the closed Codex statuses: VERIFIED / PARTIALLY_VERIFIED / FAILED / BLOCKED / NOT_RUN / UNVERIFIED.

• VERIFIED — the stage's evidence is complete and the result is green.
• PARTIALLY_VERIFIED — the stage ran on a subset of its scope; the unran subset is enumerated in the qa-report.
• FAILED — the stage ran and an assertion did not hold.
• BLOCKED — pre-condition refused execution (e.g. dev server down for LOCAL_RUNTIME_QA).
• NOT_RUN — the stage was not executed in this run. A mandatory stage carrying NOT_RUN forces aggregate UNVERIFIED (see below); the only way around that is a signed exception (W4).
• UNVERIFIED — the stage ran but evidence cannot establish the result (e.g. tool returned ambiguous output, screenshot missing).

Aggregate Status Rule

aggregate_status = weakest non-NOT_RUN stage status, where the
weakness ordering is:

VERIFIED < PARTIALLY_VERIFIED < UNVERIFIED < FAILED < BLOCKED

(VERIFIED is the strongest; BLOCKED is the weakest non-NOT_RUN value.)

THEN, if ANY mandatory stage (per the UC-type matrix below) is NOT_RUN
AND no signed exception covers it:
  aggregate_status := UNVERIFIED  (forced floor)

So a UC with WIRE_CONTRACT_QA: VERIFIED, PROVIDER_FIXTURE_QA: VERIFIED, and LIVE_PROVIDER_SMOKE: NOT_RUN (where LIVE_PROVIDER_SMOKE is mandatory for the UC type) has aggregate UNVERIFIED — not VERIFIED. The aggregate is recorded into the Status: line of the QA report; the headline string (e.g. QA COMPLETE vs QA APPLIED — UNVERIFIED) is decoration only.

Mandatory-stage matrix per UC type

Defaults (overridable per project via config.yaml → qa_mandatory_stages):

UC trait	Mandatory stages	Optional stages
actor == SYSTEM (background workers, schedulers, no user surface)	LOCAL_RUNTIME_QA, WIRE_CONTRACT_QA	COMPONENT_QA, PROVIDER_FIXTURE_QA, LIVE_PROVIDER_SMOKE, PROD_GOLDEN_PATH
actor != SYSTEM, no provider dependency	COMPONENT_QA, LOCAL_RUNTIME_QA, WIRE_CONTRACT_QA, PROVIDER_FIXTURE_QA	LIVE_PROVIDER_SMOKE, PROD_GOLDEN_PATH
actor != SYSTEM, has provider dependency	COMPONENT_QA, LOCAL_RUNTIME_QA, WIRE_CONTRACT_QA, PROVIDER_FIXTURE_QA, LIVE_PROVIDER_SMOKE	PROD_GOLDEN_PATH
Release-gate UCs (declared in release plan)	All six	(none)

Notes:

• For UCs with actor != SYSTEM the minimum mandatory stages are WIRE_CONTRACT_QA and PROVIDER_FIXTURE_QA (the latter degenerates to a no-op stage when there is no provider — recorded as VERIFIED with evidence n/a — no provider dependency declared).
• A UC has a "provider dependency" when its impl-brief or external-contracts artifact declares an external API call (kie.ai, Deepgram, Anthropic, Stripe, etc.).
• The matrix above is the default. A project can override per-stage mandatoriness in config.yaml (see next section). Override sets defaults; it is NOT a per-run gate bypass.

qa_mandatory_stages override (config.yaml)

Defaults can be customised per project:

# config.yaml
qa_mandatory_stages:
  default:
    - LOCAL_RUNTIME_QA
    - WIRE_CONTRACT_QA
  by_uc_trait:
    "actor != SYSTEM":
      - COMPONENT_QA
      - LOCAL_RUNTIME_QA
      - WIRE_CONTRACT_QA
      - PROVIDER_FIXTURE_QA
    "provider_dependency":
      - LIVE_PROVIDER_SMOKE
  per_uc:
    UC-300:
      - LIVE_PROVIDER_SMOKE
      - PROD_GOLDEN_PATH

Semantics:

• The override sets the project's default mandatory-stage set. It does NOT bypass a gate; running a single UC under this matrix still produces aggregate UNVERIFIED if a mandatory stage is NOT_RUN.
• To bypass a gate (e.g. run a release with LIVE_PROVIDER_SMOKE intentionally NOT_RUN), file a signed exception per W4 with affected_gates: [LIVE_PROVIDER_SMOKE].

Worked example — project-beta provider-skip episode

Before (current behavior, project-beta-postmortem § 3.3, § 3.8): UC-300 needed kie.ai. KIE_API_KEY was absent in the QA environment. Today's tl-qa marks the entire QA dimension as skipped → ships to prod under QA APPLIED — UNVERIFIED (non-blocking) → first real call 404s.

After (this skill, post-W3): The six stages are evaluated independently:

Stage	Status (after)	Why
COMPONENT_QA	VERIFIED	The UI surface renders.
LOCAL_RUNTIME_QA	VERIFIED	FE+BE+worker boot; route mounts.
WIRE_CONTRACT_QA	VERIFIED	Adapter sends Anthropic-shaped envelope; api-contract test passes.
PROVIDER_FIXTURE_QA	VERIFIED	Recorded kie.ai fixture; adapter parses content[] array.
LIVE_PROVIDER_SMOKE	NOT_RUN	No KIE_API_KEY in environment.
PROD_GOLDEN_PATH	NOT_RUN	Not yet deployed.

For a provider-dep UC, LIVE_PROVIDER_SMOKE is mandatory. Aggregate is forced to UNVERIFIED. Release is refused unless a signed exception covering LIVE_PROVIDER_SMOKE is filed. The pre-provider pipeline (ffmpeg, storage, queue, route mount) is no longer hidden behind the provider-key gate — its earlier silent stall would have been caught by LOCAL_RUNTIME_QA + WIRE_CONTRACT_QA.

--skip-e2e flag policy

The skill exposes exactly one operator flag for stage selection:

/nacl-tl-qa UC### --skip-e2e

Scope: --skip-e2e marks the LIVE_PROVIDER_SMOKE and PROD_GOLDEN_PATH stages as NOT_RUN for this run only. It does NOT mark any other stage as NOT_RUN. It is NOT a bulk QA bypass.

• --skip-e2e may leave aggregate VERIFIED only if neither LIVE_PROVIDER_SMOKE nor PROD_GOLDEN_PATH is mandatory for this UC (per the matrix above and any project override).
• If either stage is mandatory for this UC, --skip-e2e produces aggregate UNVERIFIED (NOT_RUN on a mandatory stage). The user must either:
  1. Run the stage; or
  2. File a signed exception per W4 with affected_gates enumerating the specific stage names (no blanket overrides).
• --skip-e2e is the single preserved skip-style flag. The bulk-QA-skip flag (formerly written as --skip followed immediately by -qa) has been removed from every skill in W3. Bulk-bypass needs are handled by emergency mode (W4).

Trigger

Command	Description
/nacl-tl-qa UC###	Run E2E QA for a UC task

Prerequisites

Configuration Resolution

Data	Source priority
Frontend URL/port	impl-brief-fe.md > config.yaml → modules.frontend.port > default 3000
Backend URL/port	impl-brief.md > config.yaml → modules.backend.port > default 3001
Reports mode	config.yaml → reports.mode (fallback: "local")
Reports path	config.yaml → reports.local_path (fallback: .tl/reports)
Remote publish	config.yaml → reports.ssh_host (only if mode: "remote")
Test credentials	config.yaml → credentials.[role] (email, password, phone, role)

If reports section missing or mode is "local" → save to .tl/reports/ only. Always save locally.

1. Task Readiness

Read .tl/tasks/UC###/status.json and confirm:

• phases.sync = done (BE and FE are synchronized)
• phases.stubs = done (no critical stubs remain)

If not met, report the current state and suggest /nacl-tl-sync UC### or /nacl-tl-stubs UC###.

2. Dev Servers Running

Verify both servers are accessible by navigating to them:

playwright_navigate -> frontend URL (e.g., http://localhost:5173)
playwright_navigate -> backend health (e.g., http://localhost:3000/api/health)

Read impl-brief.md and impl-brief-fe.md to determine actual ports.

HTTP-200 assertion: both playwright_navigate calls must return HTTP 200. If either server returns a non-200 status or is unreachable:

→ emit: QA HALTED — NO_INFRA (frontend unreachable)   ← use exact label
→ halt with explicit status; do NOT exit silently
→ tell the user which URL failed and suggest starting the dev server

Do not proceed past this step unless both servers confirm HTTP 200.

3. Screenshots Directory

rm -rf .tl/qa-screenshots/UC###/
mkdir -p .tl/qa-screenshots/UC###/

What to Read

Files from .tl/tasks/UC###/:

File	Purpose	Required
acceptance.md	Primary checklist -- every criterion becomes a test	Yes
task-be.md	API behavior, endpoints, validation rules	Yes
task-fe.md	UI behavior, pages, forms, components	Yes
api-contract.md	Request/response shapes, status codes	Yes
impl-brief.md	Backend URLs, ports	Yes
impl-brief-fe.md	Frontend routes, selectors	Yes
result-be.md	What was implemented (backend)	If exists
result-fe.md	What was implemented (frontend)	If exists

---

QA Workflow

Step 0: Testable-Criteria Gate

Read acceptance.md. Count how many criteria have ui_testable == true (or equivalent — any criterion that can be verified through the browser).

IF count(ui_testable criteria) == 0:
  → emit: QA HALTED — UNVERIFIED (no testable criteria)
  → halt immediately; do NOT proceed to any Playwright calls

If at least one testable criterion exists, continue to the next step.

Step 0b: Find or Generate Scenario

Check for existing scenario:

IF .tl/scenarios/verify-UC###.md EXISTS:
  → Use it (previously generated or manually written)
ELSE:
  → Generate one from acceptance.md (see below)

Scenario generation (from acceptance criteria):

1. Read acceptance.md — extract all testable criteria
2. Read task-fe.md — extract routes, components, user flows
3. Read api-contract.md — extract endpoints for DB checkpoint verification
4. Generate .tl/scenarios/verify-UC###.md in this format:

# Verify: UC### — [Title]

## Metadata
- **Task**: UC###
- **Modules**: frontend, backend
- **Generated**: [date]
- **Source**: acceptance.md

## Prerequisites
- Dev servers running (frontend + backend)
- Test user credentials available (from `config.yaml → credentials.[role]`: email, password, phone)

## Test Data
[From acceptance.md or test fixtures if available]

## Scenario Blocks

### BLOCK 1: [Flow name]
| # | Action | Data | Expected result |
|---|--------|------|-----------------|
| 1 | Navigate to [route] | — | Page loaded, [element] visible |
| 2 | Fill [field] | [value] | Field accepts input |
| 3 | Click [button] | — | [Expected outcome] |
| 4 | Verify [result] | — | [Assertion] |

### BLOCK 2: [Error flow]
...

## DB Checkpoints (optional)
[SQL queries to verify data was saved correctly]

## Pass/Fail Criteria
All blocks PASS = test PASS. Any FAIL = test FAIL.

The scenario is saved for reuse in regression testing.

Step 1: Parse Acceptance Criteria

Read acceptance.md (and the scenario if generated) and map each criterion to a test. Classify each as UI-testable (test it) or N/A (cannot verify via UI -- mark with reason).

Requirements-coverage gate (traceability). Build the explicit matrix criterion → stage(s) → status for every criterion, not just the ones you happened to exercise. A criterion is only allowed to be N/A when it genuinely cannot be observed through the browser and it carries no provider/runtime dependency — never use N/A to drop a provider-dependent criterion (route those to LIVE_PROVIDER_SMOKE/PROD_GOLDEN_PATH). Any UI-testable criterion left unmapped (no stage exercises it) is not verified: it forces the aggregate to UNVERIFIED via the same weakest-stage floor as a NOT_RUN mandatory stage — a green run that silently skipped a required criterion must not read as VERIFIED. Record unmapped criteria alongside qa_not_run_mandatory_stages.

Step 2: Update Status

Set phases.qa to in_progress in status.json. Record qa_started timestamp.

Step 3: Execute Main Flow Scenarios

For each happy-path acceptance criterion:

a. Navigate to the target page
   -> playwright_navigate(url)
   -> playwright_screenshot(name: "step-NN-description")
   -> stat .tl/qa-screenshots/UC###/step-NN-description.png
      IF file absent or empty: mark step FAIL, append "(screenshot missing)" to step record

b. Perform user actions (use credentials from config.yaml → credentials.[role] for login/auth forms)
   -> playwright_fill / playwright_select / playwright_click
   -> playwright_screenshot(name: "step-NN-description")
   -> stat .tl/qa-screenshots/UC###/step-NN-description.png
      IF file absent or empty: mark step FAIL, append "(screenshot missing)" to step record

c. Verify the expected result
   -> playwright_get_visible_text / playwright_get_visible_html / playwright_evaluate
   -> playwright_screenshot(name: "step-NN-description")
   -> stat .tl/qa-screenshots/UC###/step-NN-description.png
      IF file absent or empty: mark step FAIL, append "(screenshot missing)" to step record

d. Record PASS or FAIL for this criterion

Example scenario for "User can create an order":

Step 01: Navigate to /orders/new
  -> playwright_navigate(url: "http://localhost:5173/orders/new")
  -> playwright_screenshot(name: "step-01-navigate-to-order-form")
  -> playwright_get_visible_text() -- confirm page shows "Create Order"

Step 02: Select a client
  -> playwright_click(selector: "[data-testid='client-select']")
  -> playwright_click(selector: "[data-testid='client-option-1']")
  -> playwright_screenshot(name: "step-02-select-client")

Step 03: Add a product item
  -> playwright_click(selector: "[data-testid='add-item-btn']")
  -> playwright_fill(selector: "input[name='quantity']", value: "2")
  -> playwright_screenshot(name: "step-03-add-product-item")

Step 04: Submit the form
  -> playwright_click(selector: "button[type='submit']")
  -> playwright_screenshot(name: "step-04-submit-order")
  -> playwright_get_visible_text() -- confirm "Order created" message
  -> playwright_evaluate(script: "window.location.pathname") -- confirm redirect

  Criterion: PASS (order created, confirmation shown, redirect happened)

Step 4: Execute Error/Validation Scenarios

Test alternative and error flows:

• Validation errors: Submit forms with empty required fields, invalid data
• Boundary values: Zero quantities, long strings, special characters
• Authorization: Access protected pages without authentication
• Not found: Navigate to non-existent resources
• Server errors: Trigger error states if possible through UI

Step 5: Generate Reports

5a: qa-report.md (always)

Create .tl/tasks/UC###/qa-report.md using nacl-tl-core/templates/qa-report-template.md. Include: frontmatter with verdict and counts, scenario description, every test step with action/expected/actual/status/screenshot, acceptance criteria table, bug descriptions (if any), verdict with conditions, recommendation.

5b: qa-report.html (always)

Generate an HTML report alongside the markdown report. Save to .tl/tasks/UC###/qa-report.html.

Structure:

<!DOCTYPE html>
<html>
<head>
  <title>QA Report: UC### — [Title]</title>
  <style>
    /* Inline styles for standalone viewing (no external CSS) */
    body { font-family: -apple-system, sans-serif; max-width: 900px; margin: 0 auto; padding: 20px; }
    .pass { color: #22c55e; } .fail { color: #ef4444; }
    .badge { padding: 4px 12px; border-radius: 4px; font-weight: bold; }
    .badge-pass { background: #dcfce7; color: #166534; }
    .badge-fail { background: #fef2f2; color: #991b1b; }
    table { border-collapse: collapse; width: 100%; }
    th, td { border: 1px solid #e5e7eb; padding: 8px; text-align: left; }
    th { background: #f9fafb; }
    img { max-width: 100%; border: 1px solid #e5e7eb; border-radius: 4px; margin: 8px 0; }
    .screenshot-grid { display: grid; grid-template-columns: 1fr 1fr; gap: 12px; }
  </style>
</head>
<body>
  <h1>QA Report: UC### — [Title]</h1>
  <p>Date: [date] | Duration: [time] | Verdict: <span class="badge badge-[pass/fail]">[PASS/FAIL]</span></p>

  <h2>Summary</h2>
  <table>
    <tr><th>Total criteria</th><td>[N]</td></tr>
    <tr><th>Tested</th><td>[N]</td></tr>
    <tr><th>Passed</th><td class="pass">[N]</td></tr>
    <tr><th>Failed</th><td class="fail">[N]</td></tr>
    <tr><th>N/A</th><td>[N]</td></tr>
    <tr><th>Bugs found</th><td>[N]</td></tr>
  </table>

  <h2>Test Steps</h2>
  <table>
    <tr><th>#</th><th>Action</th><th>Expected</th><th>Actual</th><th>Status</th></tr>
    <!-- One row per step -->
  </table>

  <h2>Screenshots</h2>
  <div class="screenshot-grid">
    <!-- Include ALL .png files from the screenshots directory, sorted alphabetically.
         Do NOT rely only on screenshots mentioned in the steps table.
         Scan the directory: ls .tl/qa-screenshots/UC###/*.png | sort
         For each file: <figure><img src="screenshots/{filename}"><figcaption>{filename}</figcaption></figure> -->
  </div>

  <h2>Bugs</h2>
  <!-- Bug descriptions if any -->

  <footer><p>Generated by /nacl-tl-qa | Claude Skills · {N} screenshots</p></footer>
</body>
</html>

Screenshots must cover ALL files from the directory — scan before generating the section:

ls .tl/qa-screenshots/UC###/*.png | sort

Use screenshots/{filename} as the relative path (screenshots will be copied to a screenshots/ subdirectory alongside the report).

5c: Save report to reports directory

Read config.yaml → reports. Resolution chain:

IF config.yaml → reports.mode == "remote" AND ssh_host is set:
  → Save locally AND publish via rsync
IF config.yaml → reports.mode == "local" OR reports section empty OR config.yaml missing:
  → Save locally only (DEFAULT)

Local save (always happens):

REPORT_DIR="$(config.reports.local_path || '.tl/reports')/qa-UC###-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$REPORT_DIR/screenshots"
cp .tl/qa-screenshots/UC###/*.png "$REPORT_DIR/screenshots/"
cp .tl/tasks/UC###/qa-report.html "$REPORT_DIR/"

The report uses screenshots/{filename} relative paths — these work correctly in $REPORT_DIR/ because screenshots are copied into $REPORT_DIR/screenshots/.

Tell the user:

Report saved: .tl/reports/qa-UC###-20260327-143200/qa-report.html
Open: open .tl/reports/qa-UC###-20260327-143200/qa-report.html

Remote publish (only if mode: "remote"):

rsync -avz "$REPORT_DIR/" \
  "${config.reports.ssh_host}:${config.reports.remote_path}/$(basename $REPORT_DIR)/"

Report URL: https://${config.reports.domain}/$(basename $REPORT_DIR)/qa-report.html

Step 5d: Create bug tasks in YouGile (if configured)

If bugs were found AND YouGile is configured (config.yaml → yougile):

Threshold from config.yaml:

yougile:
  auto_create_bugs:
    critical: true    # always (cannot be disabled)
    major: true       # default: create tasks
    minor: false      # default: skip (noise reduction)

If auto_create_bugs section is missing → use defaults above.

For each bug meeting the threshold:

1. Create a task in the Reopened column:

   create_task(
     title: "[BUG-NNN] UC###: short description",
     columnId: config.yougile.columns.reopened,
     description: "Severity: MAJOR\nFound by: /nacl-tl-qa UC###\n\nDescription: ...\nExpected: ...\nActual: ...\nScreenshot: step-NN.png",
     stickers: { task_type: "bug", module: detected_module, source: "agent" }
   )
   

2. If parent UC task exists in YouGile → link as subtask:

   add_subtask(parentTaskId: UC_task_id, childTaskId: bug_task_id)
   

3. Report to user: "Created N bug tasks in YouGile (Reopened column)"

If YouGile not configured → skip, bugs only in qa-report.

---

Step 6: Update Tracking

Every per-stage status is recorded in status.json under phases.qa_stages, regardless of the aggregate:

"phases": {
  "qa": "done | unverified | failed | halted",
  "qa_stages": {
    "component": "VERIFIED | PARTIALLY_VERIFIED | FAILED | BLOCKED | NOT_RUN | UNVERIFIED",
    "local_runtime": "...",
    "wire_contract": "...",
    "provider_fixture": "...",
    "live_provider_smoke": "...",
    "prod_golden_path": "..."
  },
  "qa_aggregate_status": "VERIFIED | PARTIALLY_VERIFIED | UNVERIFIED | FAILED | BLOCKED"
}

If aggregate VERIFIED (QA COMPLETE): phases.qa = "done", record qa_completed, qa_verdict: "QA COMPLETE".

If aggregate PARTIALLY_VERIFIED or UNVERIFIED (QA APPLIED — UNVERIFIED): phases.qa = "unverified", record qa_completed, qa_verdict set to the headline, and (when applicable) qa_not_run_mandatory_stages array enumerating the mandatory stages with NOT_RUN status.

If aggregate FAILED (QA INCOMPLETE — REGRESSION): phases.qa = "failed", record qa_completed, qa_verdict: "QA INCOMPLETE — REGRESSION", qa_failures array.
