Description
Refactoring Summary
Get the LS-4214 pr-agent consolidation PR stack (#3400 → #3401 → #3403) conflict-free, mergeable, and clear of outstanding CodeRabbit review feedback, then merge in order.

Milestones & Timeline
No fixed deadline. Note: this stack has had the same conflict recur multiple times already from concurrent pushes (Chris, Ash, CodeRabbit auto-commits) — a "same-day" resolution likely needs a brief pause on direct pushes to these 3 branches right before the final fix-and-merge attempt, otherwise expect another recurrence.
Safety Nets
N/A — this issue tracks merge/review hygiene across the LS-4214 stack (conflict resolution, review-thread status), not new application logic. Each PR's own Safety Nets/Verification section covers its code changes.
Approach
Root cause of #3403's conflict
Not just a stale branch — fix's branch was at one point independently rebased directly onto develop rather than staying stacked on refactor, breaking its true git ancestry to refactor (confirmed via git merge-base --is-ancestor, not just a content check). Because of that broken ancestry, any subsequent change to refactor — including a normal rebase/force-push, which is expected in a stacked workflow — reopens the conflict, even after it's been fixed once. Fixing this requires a real rebase of fix onto refactor's actual current tip (restoring true ancestry), not just resolving the visible file conflicts — those come back otherwise.
Merge conflicts — #3403 vs its base (10 paths, verified directly, not estimated)

Re-run git merge-tree --write-tree origin/refactor/pr-agent-skills-restructure origin/fix/pr-agent-branch-name-validation before starting work — this list moves as the branches do.
Metrics / Benchmarks (if applicable)
N/A — not a performance-related refactor.

Outstanding CodeRabbit feedback — #3400
Note: most of these are already content-fixed by later commits — the GitHub review threads just haven't auto-resolved. Verify current file content before redoing any fix.

#3403 — no CodeRabbit review posted yet
Re-trigger CodeRabbit review once the branch is rebased and conflict-free — prior attempts reported "Review rate limited."
Risk & Rollback
- Risk level: Low — this issue tracks review/merge hygiene, not code changes in itself
- Rollback plan: N/A, no direct commits from this issue
Acceptance Criteria
- All three PRs (aiops: pr-agent - plan consolidation spec, fix initial identity and lint config bugs #3400, refactor: pr-agent - restructure 6 skills into Agent Skills specification shape #3401, fix: pr-agent - correct branch-validation prefix lists, complete the pr-creation-agent merge #3403) show mergeable/CI-green status

- CodeRabbit review is re-triggered on fix: pr-agent - correct branch-validation prefix lists, complete the pr-creation-agent merge #3403 and any findings addressed
- Stack merged in order: aiops: pr-agent - plan consolidation spec, fix initial identity and lint config bugs #3400 → refactor: pr-agent - restructure 6 skills into Agent Skills specification shape #3401 → fix: pr-agent - correct branch-validation prefix lists, complete the pr-creation-agent merge #3403
- Labels/types match org standards
Additional Context
Dependencies
- Blocks any further PRs stacking on top of fix: pr-agent - correct branch-validation prefix lists, complete the pr-creation-agent merge #3403 for LS-4214 Stories 2-4
- refactor: pr-agent - restructure 6 skills into Agent Skills specification shape #3401 depends on aiops: pr-agent - plan consolidation spec, fix initial identity and lint config bugs #3400 merging or being confirmed stable
- fix: pr-agent - correct branch-validation prefix lists, complete the pr-creation-agent merge #3403 depends on refactor: pr-agent - restructure 6 skills into Agent Skills specification shape #3401's branch being stable before rebasing
