Claude Code v2.1.143: Plugin Dependency Enforcement, Cost Estimates, and Background Stability
Anthropic
Claude Code v2.1.143 shipped May 15 with plugin dependency enforcement (disable refuses when another plugin depends on the target; enable force-enables transitive dependencies), projected context cost estimates in the plugin marketplace, and a new worktree.bgIsolation:none setting for repos where worktrees are impractical. On Windows, PowerShell now passes -ExecutionPolicy Bypass by default across Bedrock, Vertex, and Foundry providers. Over 30 bug fixes address corrupt .credentials.json hangs at startup, macOS Full Disk Access errors for background agents, repeated PowerShell process spawning in claude agents, and multiple background session reliability regressions.
Why it matters
Plugin dependency graph enforcement and projected cost estimates signal the skills/plugins marketplace is becoming a first-class production surface. The PowerShell-by-default change expands enterprise readiness across all three major cloud providers. This is among the largest single-patch releases in recent Claude Code history by fix count.
