Bump PR Fixer

Finds open Renovate PRs with failing CI checks across configured repositories and uses Claude Code to diagnose and fix the failures.

Required env vars: GH_TOKEN, CLAUDE_CODE_OAUTH_TOKEN, REPOS (newline-separated list of owner/repo).

---

Step 1 — Setup

Verify required env vars and configure git for the CI runner:

[[ -n "$GH_TOKEN" && -n "$CLAUDE_CODE_OAUTH_TOKEN" && -n "$REPOS" ]] \
  || { echo "Missing required env vars"; exit 1; }

git config --global user.name  "claude-code-bot"
git config --global user.email "[e-mail]"
git config --global url."https://x-access-token:${GH_TOKEN}@github.com/".insteadOf "https://github.com/"

---

Step 2 — Process each repo

For each repo in $REPOS (skip empty lines and lines starting with #):

Find failed Renovate PRs:

gh pr list \
  --repo "$repo" \
  --author "app/renovate" \
  --state open \
  --json number,title,statusCheckRollup \
  --jq '
    [.[] | select(.statusCheckRollup[]? | .status == "COMPLETED" and .conclusion == "FAILURE")]
    | unique_by(.number)
    | [.[] | {number, title}]
  '

If the result is empty, log "no failed PRs in $repo" and continue to the next repo.

Otherwise, clone the repo:

repo_dir="/workspace/$(echo "$repo" | tr '/' '-')"
rm -rf "$repo_dir"
git clone "https://github.com/${repo}.git" "$repo_dir"

For each failed PR number, run Step 3 below. Continue on failure — one PR failing should not block the others.

After all PRs for that repo are processed, remove the clone: rm -rf "$repo_dir".

---

Step 3 — Fix a single PR

Checkout the PR branch cleanly:

cd "$repo_dir"
git reset --hard
git clean -fd
DEFAULT_BRANCH="$(git remote show origin | awk '/HEAD branch/ {print $NF}')"
git checkout "$DEFAULT_BRANCH" && git pull --quiet
gh pr checkout "$pr_number"

Delegate diagnosis and fix to a sub-agent via the Agent tool. Prompt:

This is a Renovate dependency update PR (<repo>#<pr_number>) with failing CI checks. Working directory: <repo_dir>, already on the PR branch.

Diagnose why CI is failing and fix the issue. The failure is likely caused by the dependency update requiring code changes. Pull the failing logs:

gh pr checks --json name,bucket,state,link
gh run view <run-id> --log-failed   # run-id is the path segment after "/runs/" in link

Make minimal targeted fixes — do not refactor unrelated code. After fixing, stage your changes with git add. Do not commit or push; the lead will handle that.

Allowed tools for the sub-agent: Bash, Read, Edit, Write, Glob, Grep.

After the sub-agent returns:

git diff --cached --quiet && echo "no changes" || echo "changes staged"

• No changes → record "no changes needed" for this PR, continue.
• Changes staged → invoke /ship via the Skill tool with the message fix: resolve CI failures for dependency update. /ship commits, rebases, pushes, and ensures the PR has auto-merge.

If the sub-agent errors (tool failure, timeout), record "claude_failed" for this PR and continue.
