What it does

E2E Verify Fix is an agent skill from redhat-developer/rhdh. Verify an E2E test fix by running the test multiple times and checking code quality

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering End-to-end testing, Code quality and Platform engineering. It works with Playwright. The repository describes itself as: The repo formerly known as janus-idp/backstage-showcase. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit ef35b18. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- yarn
- npx

From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- playwright.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

E2E Verify Fix loads about 1.3k tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 514 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~25
When it runs · the whole SKILL.md, loaded when a task matches: ~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Ensure the `.env` file exists — generate it with `source local-test-setup.sh <showcase|rbac> --env`. To regenerate (e.g.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Verify Fix

Verify that the test fix works reliably and passes all code quality checks.

When to Use

Use this skill after implementing a fix (via e2e-diagnose-and-fix) to confirm the fix works before submitting a PR.

MANDATORY: Use the Playwright Healer Agent for Verification

Always use the Playwright healer agent for test verification. The healer provides step-by-step debugging if a run fails, making it faster to iterate on fixes.

Note: The Playwright healer agent is currently supported in OpenCode and Claude Code only. In Cursor or other tools without Playwright agent support, skip the healer initialization and use direct test execution for all verification steps (yarn playwright test ...).

Healer Initialization

If not already initialized in this session, initialize the healer agent in e2e-tests/:

bash

cd e2e-tests

# For OpenCode
npx playwright init-agents --loop=opencode

# For Claude Code
npx playwright init-agents --loop=claude

See https://playwright.dev/docs/test-agents for the full list of supported tools and options. The generated files are local tooling — do NOT commit them.

Ensure the .env file exists — generate it with source local-test-setup.sh <showcase|rbac> --env. To regenerate (e.g. after token expiry), re-run the same command.

Verification Steps

1. Single Run Verification via Healer

Invoke the healer agent to run the fixed test once:

Task: "You are the Playwright Test Healer agent. Verify a fix by running the test once.
Working directory: <path>/e2e-tests
Run: set -a && source .env && set +a && npx playwright test <spec-file> --project=any-test --retries=0 --workers=1 -g '<test-name>'
If it passes, report success. If it fails, examine the error and report what went wrong."

If it fails, go back to e2e-diagnose-and-fix and iterate — use the healer agent there too for the fix.

2. Multi-Run Stability Check

Run the test 5 times consecutively to verify no flakiness was introduced:

bash

cd e2e-tests
set -a && source .env && set +a
PASS=0; FAIL=0
for i in $(seq 1 5); do
  echo "=== Stability run $i/5 ==="
  if npx playwright test <spec-file> --project=any-test --retries=0 --workers=1 2>&1; then
    PASS=$((PASS + 1))
  else
    FAIL=$((FAIL + 1))
  fi
done
echo "Stability results: $PASS/5 passed"

Acceptance criteria: 5/5 passes. If any run fails, invoke the healer agent on the failing run to diagnose and fix the remaining issue — do not manually guess at fixes.

Show full SKILL.md (267 more words)Show less

3. Full Project Stability Check

When to run: This step is required if the failure was only reproducible when running the full CI project (CI=true yarn playwright test --project=<ci-project>) during e2e-reproduce-failure. If the failure reproduced in isolated single-test runs, this step is optional but still recommended.

Run the full project to confirm the fix holds under CI-like concurrency:

bash

cd e2e-tests
set -a && source .env && set +a
CI=true yarn playwright test --project=<ci-project> --retries=0

Replace <ci-project> with the project from the CI failure (e.g., showcase, showcase-rbac). This verifies the fix under the same worker count and test interaction conditions that triggered the original failure.

Acceptance criteria: The full project run must pass. If the fixed test still fails when run alongside other tests, the fix is incomplete — return to e2e-diagnose-and-fix.

IMPORTANT: Never skip verification steps. If you cannot run tests (e.g., no cluster available, environment issues), stop and ask the user for explicit approval before proceeding without verification. Do not assume it's OK to skip.

4. Code Quality Checks

Run all code quality checks in the e2e-tests workspace:

bash

cd e2e-tests

# TypeScript compilation
yarn tsc:check

# ESLint
yarn lint:check

# Prettier formatting
yarn prettier:check

Fix any issues found:

bash

# Auto-fix lint issues
yarn lint:fix

# Auto-fix formatting
yarn prettier:fix

5. Optional: Full Project Regression Check

If the fix touches shared utilities or page objects, run the entire Playwright project to check for regressions:

bash

cd e2e-tests
yarn playwright test --project=<project> --retries=0

This is optional for isolated spec file changes but recommended for changes to:

e2e-tests/playwright/utils/ (utility classes)
e2e-tests/playwright/support/ (page objects, selectors)
e2e-tests/playwright/data/ (shared test data)
playwright.config.ts (configuration)

6. Review the Diff

Before submitting, review all changes:

bash

git diff
git diff --stat

Verify:

Only intended files were changed
No secrets or credentials were added
No unrelated changes were included
Component annotations are present in any new/modified spec files
Semantic selectors are used (no deprecated CSS class selectors)

Result Summary

After verification, produce a summary:

Fix Verification Results:
- Test: <spec-file> (<project>)
- Single run: PASS
- Stability (5 runs): 5/5 PASS
- TypeScript: PASS
- ESLint: PASS
- Prettier: PASS
- Files changed: <list>
- Ready for PR: YES/NO
