CI Flake Triage

Use this skill to turn noisy JUnit retry artifacts into a focused flaky-test report.

What this skill does

• Reads one or more JUnit XML files (for example: first run + rerun artifacts)
• Aggregates status per test case (passed, failed, skipped, error)
• Flags flaky candidates when a test has both fail-like and pass outcomes
• Separates persistent failures from flaky failures
• Prints top flaky tests to prioritize stabilization work

Inputs

Optional:

• JUNIT_GLOB (default: test-results/**/*.xml)
• TRIAGE_TOP (default: 20)
• OUTPUT_FORMAT (text or json, default: text)
• FAIL_ON_PERSISTENT (0 or 1, default: 0) — exit non-zero when persistent failures exist
• FAIL_ON_FLAKE (0 or 1, default: 0) — exit non-zero when flaky candidates exist

Run

Text report:

JUNIT_GLOB='artifacts/junit/**/*.xml' \
TRIAGE_TOP=15 \
bash skills/ci-flake-triage/scripts/triage-flakes.sh

JSON output for CI ingestion:

JUNIT_GLOB='artifacts/junit/**/*.xml' \
OUTPUT_FORMAT=json \
FAIL_ON_PERSISTENT=1 \
bash skills/ci-flake-triage/scripts/triage-flakes.sh

Run with bundled fixtures:

JUNIT_GLOB='skills/ci-flake-triage/fixtures/*.xml' \
bash skills/ci-flake-triage/scripts/triage-flakes.sh

Output contract

• Exit 0 when no fail gates are enabled (default)
• Exit 1 if FAIL_ON_PERSISTENT=1 and persistent failures are found
• Exit 1 if FAIL_ON_FLAKE=1 and flaky candidates are found
• In text mode, prints summary + top flaky + persistent failures
• In json mode, prints machine-readable summary and testcase details
