From a589e4cebf372a5ff1c9e809a440729979a0e861 Mon Sep 17 00:00:00 2001 From: Marcin Polewski Date: Fri, 30 Oct 2026 22:17:32 -0600 Subject: [PATCH 01/11] Read per-repository settings from .github/code-review/ on the default branch gather() reads config.yml (sensitive, skip, policies, tiers), guidance.md and reviewers/*.md from the base checkout only, never the pull request's head. config.yml is a small YAML subset checked by a hand-written schema; anything unusable is a warning in the check run and the defaults, not a failed run. Policies join the conventions within their own budget and must resolve inside the checkout; skipped files are listed in the check run; project reviewers join the roster as project: and their paths: frontmatter adds them to the floor. --- CHANGELOG.md | 4 + README.md | 58 +++++++ src/config.ts | 12 +- src/context.ts | 6 +- src/gather.ts | 71 +++++++- src/main.ts | 13 +- src/results.ts | 13 +- src/review.ts | 54 +++++- src/settings.ts | 389 ++++++++++++++++++++++++++++++++++++++++++ test/settings.test.ts | 312 +++++++++++++++++++++++++++++++++ 10 files changed, 907 insertions(+), 25 deletions(-) create mode 100644 src/settings.ts create mode 100644 test/settings.test.ts diff --git a/CHANGELOG.md b/CHANGELOG.md index f12b923..37f254c 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -6,6 +6,10 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), ## [Unreleased] +### Added + +- Per-repository settings in `.github/code-review/`, read from the default branch's checkout only, so a pull request that edits them is reviewed with the default branch's copy: `config.yml` (`sensitive:`, `skip:`, `policies:`, `tiers:`), `guidance.md` rules for the context stage, and `reviewers/*.md` project reviewers that join the roster as `project:`.

A project reviewer's frontmatter is validated (paths: only, a list of globs or one comma-separated string), shares the frontmatter split and glob list with the instruction files, and its warning loses a stray colon. parseYaml refuses a __proto__ key. A tiers: name matching no reviewer is a check-run warning, and a pull request whose every changed file is skipped by config runs no model. Drop the ?? fallbacks on fields gather always sets, cite issue #42 as the convention asks, and test the size limits, truncation, unreadable files, a reviewers path that isn't a folder, projectRoster and fileList. --- CHANGELOG.md | 2 +- README.md | 11 +-- src/gather.ts | 15 ++-- src/main.ts | 3 +- src/review.ts | 40 +++++++++-- src/settings.ts | 156 +++++++++++++++++++++++++++++------------- test/settings.test.ts | 132 +++++++++++++++++++++++++++++++++-- 7 files changed, 285 insertions(+), 74 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 3e783b4..35fe2c5 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -8,7 +8,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), ### Added -- Per-repository settings in `.github/code-review/`, read from the default branch's checkout only, so a pull request that edits them is reviewed with the default branch's copy: `config.yml` (`sensitive:`, `skip:`, `policies:`, `tiers:`), `guidance.md` rules for the context stage, and `reviewers/*.md` project reviewers that join the roster as `project:`.
