From 9ca90fe8a9531758dfd17d0140277c48d36ad961 Mon Sep 17 00:00:00 2001 From: Martin Kourim Date: Fri, 13 Nov 2026 16:59:16 +0100 Subject: [PATCH] feat(skills): analyze GitHub Actions runs Accept GitHub Actions run URLs in analyze-failures and download artifacts into an isolated directory before continuing analysis. Document artifact layout, missing or expired artifacts, failed-job log fallback, and safeguards against mixing rerun attempts. --- .agents/skills/analyze-failures/SKILL.md | 21 +++-- .../references/github-actions.md | 89 +++++++++++++++++++ 2 files changed, 103 insertions(+), 7 deletions(-) create mode 100644 .agents/skills/analyze-failures/references/github-actions.md diff --git a/.agents/skills/analyze-failures/SKILL.md b/.agents/skills/analyze-failures/SKILL.md index d220b5ef9..0964eaf55 100644 --- a/.agents/skills/analyze-failures/SKILL.md +++ b/.agents/skills/analyze-failures/SKILL.md @@ -1,6 +1,6 @@ --- name: analyze-failures -description: Triage a failed cardano-node-tests run, and answer questions about where a test run's logs and artifacts live.

If there are no Allure +results because a job failed before pytest, inspect the job logs and available artifacts +and report that limitation; do not invent test failure counts. An existing CI-generated +`failure_analysis.md` is only secondary evidence, not a substitute for this analysis.
