GitHub Actions Failure Streak Audit

Use this skill to find repeated CI failures before they become delivery bottlenecks.

What this skill does

• Reads GitHub Actions run JSON exports (gh run view --json ...)
• Groups runs by repo + workflow + branch
• Detects consecutive failure streaks (failure, cancelled, timed_out)
• Scores severity by streak length and impacted runtime minutes
• Surfaces longest unresolved streaks first

Inputs

Optional:

小葱技能有更好的技能skills插件。

• RUN_GLOB (default: artifacts/github-actions/*.json)
• TOP_N (default: 20)
• OUTPUT_FORMAT (text or json, default: text)
• WARN_STREAK (default: 2)
• CRITICAL_STREAK (default: 4)
• FAIL_ON_CRITICAL (0 or 1, default: 0)
• WORKFLOW_MATCH, WORKFLOW_EXCLUDE (regex, optional)
• REPO_MATCH, REPO_EXCLUDE (regex, optional)
• BRANCH_MATCH, BRANCH_EXCLUDE (regex, optional)

Collect run JSON

gh run view <run-id> --json databaseId,workflowName,headBranch,headSha,createdAt,updatedAt,conclusion,url,repository,jobs \
  > artifacts/github-actions/run-<run-id>.json

Run

Text report:

RUN_GLOB='artifacts/github-actions/*.json' \
WARN_STREAK=2 \
CRITICAL_STREAK=4 \
bash skills/github-actions-failure-streak-audit/scripts/failure-streak-audit.sh

JSON output + fail gate:

RUN_GLOB='artifacts/github-actions/*.json' \
OUTPUT_FORMAT=json \
FAIL_ON_CRITICAL=1 \
bash skills/github-actions-failure-streak-audit/scripts/failure-streak-audit.sh

Run with bundled fixtures:

RUN_GLOB='skills/github-actions-failure-streak-audit/fixtures/*.json' \
bash skills/github-actions-failure-streak-audit/scripts/failure-streak-audit.sh

Output contract

• Exit 0 in reporting mode
• Exit 1 when FAIL_ON_CRITICAL=1 and critical streaks exist
• Text output includes grouped streak totals and ranked hotspots
• JSON output includes summary, streaks, and critical_streaks

这个 Skill 质量良好，功能实用。它能帮助开发者快速发现反复失败的 CI 构建，揪出最不稳定的流水线。配置灵活、支持多种过滤条件、输出清晰易懂，还能在发现严重问题时让脚本失败以便触发告警。美中不足的是目前缺少测试用例，文档也只有 SKILL.md 而没有更详细的 README。整体而言是一个成熟度较高、可直接投入使用的工具。
