Agent Worktree Isolation

Required Read

• Before concurrent repository inspection or writes, worktree or branch lifecycle operations, or cleanup reporting, or relying on any exception to this rule, read skills/coding-contracts/references/agent-worktree-isolation.md in full.
• Its full text and named sections bind as rule content.
• Resolve the reference within its owning installed plugin.
• Missing or unreadable content stops the affected action until the plugin is repaired.
• Read explicitly when triggered.
• Never @-import the reference.

Boundary

• Isolate writes that may run concurrently with another agent in a separate git worktree and task branch.
• Main-checkout concurrent inspection stays read-only.
• Preserve unrelated work.
• Remove only this task's owned worktree through the binding cleanup order.
• During cleanup, never touch or report a protected origin branch.
• A single-machine single-agent workflow may proceed without a worktree.
