Git worktrees aren't enough for parallel AI agents

Short summary

Git worktrees isolate AI agents' working directories but don't prevent semantic merge conflicts when parallel PRs land on main. A study of 142k+ agent PRs found a 27.67% merge-conflict rate, with quieter failures where git merges cleanly but logic breaks later. Existing tools—git, CI, code review, merge queues—each examine a single PR in isolation, leaving cross-PR relationships unmonitored. The article pitches Veripsa Core as an advisory GitHub check that warns about overlapping open PRs before they reach main.

• •Worktrees solve execution isolation but not semantic merge conflicts between parallel agent PRs
• •Study of 142k+ agent PRs shows 27.67% merge-conflict rate; silent conflicts are worse
• •Veripsa Core pitched as cross-PR advisory layer detecting overlapping changes before merge
