From ee733def078d1dd317a924405a6f6f8de382bf53 Mon Sep 17 00:00:00 2001 From: Jeremy Massel <1123407+jkmassel@users.noreply.github.com> Date: Wed, 28 Oct 2026 13:46:50 -0600 Subject: [PATCH 01/44] Add an experimental Claude PR review CI check Claude reviews each internal PR on a Mac CI agent with full shell access, so it can build, run tests and use simulators. The step fails only when Claude proves a bug caused by the PR. Claude runs with an allowlisted environment (the Anthropic key and the test site sign-in) and has no GitHub or Buildkite agent token. The script fetches the PR data for it and posts its result as a comment-only review. --- .buildkite/claude/pr-review-ci-context.md | 43 +++++ .buildkite/claude/pr-review-prompt.md | 1 + .buildkite/claude/pr-review-schema.json | 45 +++++ .buildkite/commands/claude-pr-review.sh | 218 ++++++++++++++++++++++ .buildkite/pipeline.yml | 22 +++ 5 files changed, 329 insertions(+) create mode 100644 .buildkite/claude/pr-review-ci-context.md create mode 100644 .buildkite/claude/pr-review-prompt.md create mode 100644 .buildkite/claude/pr-review-schema.json create mode 100755 .buildkite/commands/claude-pr-review.sh diff --git a/.buildkite/claude/pr-review-ci-context.md b/.buildkite/claude/pr-review-ci-context.md new file mode 100644 index 000000000000..77cc0a5b901c --- /dev/null +++ b/.buildkite/claude/pr-review-ci-context.md @@ -0,0 +1,43 @@ +# Running in CI + +You are a CI check, running unattended in a Buildkite job on a throwaway macOS VM.

The script now creates a non-admin claude-reviewer user with its own group and a copy of the checkout, and runs Claude as that user over SSH to the VM (or with launchctl asuser). Before Claude starts, the reviewer checks that it can't read those files or process environments, signal the build user's processes, or use sudo. If any check fails, Claude doesn't run. It also reports whether simulators and Xcode MCP work for the second user. --- .../commands/claude-pr-review-as-reviewer.sh | 125 ++++++++++++ .buildkite/commands/claude-pr-review.sh | 187 +++++++++++------- 2 files changed, 241 insertions(+), 71 deletions(-) create mode 100755 .buildkite/commands/claude-pr-review-as-reviewer.sh diff --git a/.buildkite/commands/claude-pr-review-as-reviewer.sh b/.buildkite/commands/claude-pr-review-as-reviewer.sh new file mode 100755 index 000000000000..50f01c396bcf --- /dev/null +++ b/.buildkite/commands/claude-pr-review-as-reviewer.sh @@ -0,0 +1,125 @@ +#!/bin/bash +# Runs as the unprivileged `claude-reviewer` user, started by claude-pr-review.sh. +# Checks that this user can't reach the build user's secrets, then runs Claude. +# +# Exit status: 0 = Claude ran (the verdict is in the transcript), 3 = an +# isolation check failed and Claude did not run, anything else = an error. + +set -euo pipefail + +# shellcheck source=/dev/null +source "$HOME/review.env" +cd "$HOME/wordpress-ios" +export PATH="$HOME/.local/bin:/opt/homebrew/bin:/usr/bin:/bin:/usr/sbin:/sbin" +mkdir -p "$EVIDENCE_DIR" +report="$EVIDENCE_DIR/isolation-checks.txt" +: > "$report" + +# ── Isolation checks ───────────────────────────────────────────────── +# Prints only file names and variable names, never contents or values. +echo "--- :lock: Isolation checks as $(id -un)" +leaks=0 +check() { # $1 = OK|LEAK, $2 = description + echo "$1 $2" | tee -a "$report" + if [[ "$1" == LEAK ]]; then leaks=$((leaks + 1)); fi +} + +# Folders where the build user's secrets live.

The logs are now uploaded in parts every two minutes to build/claude-audit-live/, each checked for the job's secrets first. The Endpoint Security log was 266 MB after six minutes, mostly reads of system files, Xcode and the reviewer's own folders. Those are now counted instead of logged; reads anywhere else are still listed. eslogger ignores SIGINT, so it now gets SIGTERM next, and the signal that stopped each logger is recorded. --- .buildkite/claude/audit-cut.py | 41 +++++ .buildkite/claude/audit-es-filter.py | 106 +++++++++++ .buildkite/claude/audit-summarize.py | 124 +++++++------ .buildkite/claude/audit.sh | 230 ++++++++++++++++-------- .buildkite/commands/claude-pr-review.sh | 4 +- .buildkite/pipeline.yml | 3 +- 6 files changed, 372 insertions(+), 136 deletions(-) create mode 100644 .buildkite/claude/audit-cut.py create mode 100644 .buildkite/claude/audit-es-filter.py diff --git a/.buildkite/claude/audit-cut.py b/.buildkite/claude/audit-cut.py new file mode 100644 index 000000000000..f3739a1defcd --- /dev/null +++ b/.buildkite/claude/audit-cut.py @@ -0,0 +1,41 @@ +"""Copies the lines added to a growing log since the last call into a new file. + +Used to upload the Claude PR review's audit logs in parts while the review +runs.
