From 48f31198201f0a78c91a0a497040782c0aaaff69 Mon Sep 17 00:00:00 2001 From: peptiderepo <273788462+peptiderepo@users.noreply.github.com> Date: Tue, 14 Apr 2026 16:45:47 +0700 Subject: [PATCH] ci: add review gate (tripwire audit + Claude auto-review via OpenRouter) (#1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * ci: add main-push audit tripwire Flags direct pushes to main that did not come from a merged PR. Free-plan workaround since branch protection requires GitHub Pro. * docs: add Git Workflow section to CONVENTIONS.md Documents the PR-gated review process enforced at the agent layer. Free-plan workaround since branch protection requires GitHub Pro. * ci: add Claude-powered CTO PR review workflow Auto-reviews every PR with Claude Haiku 4.5 and posts a structured review (APPROVE / REQUEST_CHANGES / COMMENT). Does NOT auto-merge — a human still clicks Merge. Requires ANTHROPIC_API_KEY secret on the repo. * ci: switch CTO reviewer from Anthropic direct to OpenRouter Reuses the OPENROUTER_API_KEY secret that already backs the other AI plugins. Consolidates AI spend on one bill.
