Buildkite Playwright failure extraction

Use this skill when you need a compact, human-readable overview of failing Playwright tests from Buildkite job logs.

This workflow uses the bkci CLI. Run /skill:buildkite-cli first if bkci is not set up yet.

Quick start (script)

./scripts/extract-playwright-failures.cjs --org ORG --pipeline PIPELINE --build BUILD_NUMBER

Options:

• --bkci-path PATH (default: bkci or $BKCI_BIN)
• --error-for TEST_NAME (fetch error details for a single test)
• --job-id ID (required with --error-for)
• --job-url URL (optional with --error-for)
• --failed-line-row N (optional with --error-for)

Output

The script always emits JSON and caches summary results under your temp dir ($TMPDIR/pi-buildkite-playwright-failures). It refreshes the cache if any Playwright job state changes.

Summary output includes:

• summary
• jobs[] entries with:
  • jobName, jobId, jobUrl, label, state
  • failedLine, failedLineRow
  • tests (string list)
  • testEntries (objects with name + row)
  • error

Error lookup output (--error-for) includes:

• error.testName, error.jobId, error.jobUrl
• error.matchRow, error.startRow, error.endRow
• error.lines (array of log lines)
• meta.checkedAt

When presenting results to a human, format the summary with:

• failed job count
• unique failing tests count
• tests failing in all environments (label as all)
• tests failing in multiple environments
• tests failing in only one environment

What the script does

• Fetches the build with bkci --raw builds get.
• Filters for failed Playwright jobs.
• Fetches each failed job log with bkci jobs log get.
• Locates the X failed summary section and extracts failed test lines.

Manual steps (if the script fails)

1. Fetch build details:

bkci --raw builds get --org ORG --pipeline PIPELINE --build BUILD_NUMBER

2. Find failed Playwright jobs from data.jobs[].

3. Fetch a job log:

bkci jobs log get --org ORG --pipeline PIPELINE --build BUILD_NUMBER --job JOB_ID

4. Extract failed test lines under the X failed section.

Notes

• bkci jobs log get returns cleaned logs (ANSI/control sequences stripped) in normalized mode.
• If auth is missing, do not run auth setup automatically. Ask the user to run bkci auth setup manually.
