From 4c65e7b32821f7913d9f2d0a462687e323c118e2 Mon Sep 17 00:00:00 2001 From: Cristian Greco Date: Thu, 8 Oct 2026 20:34:51 +0100 Subject: [PATCH] Add agent skills for recurring repo workflows Move step-by-step workflows out of AGENTS.md into skills under .agents/skills (read by Codex), symlinked into .claude/skills (read by Claude Code): open-pr, review-pr, add-module, triage-issue, diagnose-ci, update-dependencies and publish-release. AGENTS.md keeps the rules that apply to every task, adds verification, image pinning and CommonJS dependency rules, and fixes the Vitest sequential guidance for Vitest 5. The bug report template now asks for DEBUG logs, the container runtime, the test runner and the last working version. --- .agents/skills/add-module/SKILL.md | 40 ++++++++ .agents/skills/diagnose-ci/SKILL.md | 50 ++++++++++ .agents/skills/open-pr/SKILL.md | 61 ++++++++++++ .agents/skills/publish-release/SKILL.md | 68 +++++++++++++ .agents/skills/review-pr/SKILL.md | 64 ++++++++++++ .agents/skills/triage-issue/SKILL.md | 78 +++++++++++++++ .agents/skills/update-dependencies/SKILL.md | 60 +++++++++++ .claude/skills/add-module | 1 + .claude/skills/diagnose-ci | 1 + .claude/skills/open-pr | 1 + .claude/skills/publish-release | 1 + .claude/skills/review-pr | 1 + .claude/skills/triage-issue | 1 + .claude/skills/update-dependencies | 1 + .github/ISSUE_TEMPLATE/bug_report.md | 18 +++- AGENTS.md | 104 ++++---------------- 16 files changed, 462 insertions(+), 88 deletions(-) create mode 100644 .agents/skills/add-module/SKILL.md create mode 100644 .agents/skills/diagnose-ci/SKILL.md create mode 100644 .agents/skills/open-pr/SKILL.md create mode 100644 .agents/skills/publish-release/SKILL.md create mode 100644 .agents/skills/review-pr/SKILL.md create mode 100644 .agents/skills/triage-issue/SKILL.md create mode 100644 .agents/skills/update-dependencies/SKILL.md create mode 120000 .claude/skills/add-module create mode 120000 .claude/skills/diagnose-ci create mode 120000 .claude/skills/open-pr create mode 120000 .claude/skills/publish-release create mode 120000 .claude/skills/review-pr create mode 120000 .claude/skills/triage-issue create mode 120000 .claude/skills/update-dependencies diff --git a/.agents/skills/add-module/SKILL.md b/.agents/skills/add-module/SKILL.md new file mode 100644 index 000000000..4649f9b8e --- /dev/null +++ b/.agents/skills/add-module/SKILL.md @@ -0,0 +1,40 @@ +--- +name: add-module +description: Adds a new Testcontainers module under packages/modules (container class, tests, Dockerfile image pin, docs page, mkdocs nav), or brings a contributor's module PR up to the repo's conventions.
