From 07cc487f854334137125e75a2ea3fbe52ec31ab2 Mon Sep 17 00:00:00 2001 From: Tiago Kochenborger Date: Mon, 6 Jul 2026 12:01:05 -0300 Subject: [PATCH 1/3] =?UTF-8?q?feat(sdk-review):=20batch=206/6=20=E2=80=94?= =?UTF-8?q?=20wire-up=20+=20docs=20+=20CONTRIBUTING=20amendment?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Final batch that turns the collection of checks into a working skill: ## Orchestration (.claude/scripts/) - orchestrate.sh — main entry point. Runs preflight, dispatches all 20 checks in parallel, applies baseline + tier gating, posts 4 signals (inline comments, summary, check-run, label) unless --dry-run. - aggregate.sh — merges N check reports into a single summary; applies rules.yaml tiers to each finding. ## Slash command (.claude/commands/) - review-new-module.md — Claude Code slash command that invokes orchestrate.sh ## GitHub Actions (.github/workflows/) - sdk-module-review.yml — auto-trigger on every PR (opened/synchronize/reopened/ready_for_review) + workflow_dispatch - sdk-skill-isolation-check.yml — validates sub-PRs into feat/sdk-review-skill (shellcheck, ruff, bats, size budget, fixtures per check) ## Docs - docs/PR-REVIEW.md — user-facing guide (rules, severities, suppression, BTP dep documentation, breaking changes, tuning noisy rules) - docs/BRANCH-PROTECTION-SETUP.md — admin guide (UI + gh CLI) to configure sdk-module-review as required status check + SHADOW→FLAG→BLOCK rollout ## CONTRIBUTING.md - New section: 'AI-assisted contribution skills — required for review' - States clearly that reviewers will NOT review PRs where sdk-module-review is failing/missing - Documents /review-new-module local + CI auto-trigger ## After merging this batch The skill is fully operational. See docs/BRANCH-PROTECTION-SETUP.md to configure the check-run as a required status check. Part 6 of 6.
