Worktree Night Shift -- Wake Up to a Reviewable Commit

Give an agent one night, not the keys to the building.

Worktree Night Shift runs a single, tightly scoped coding task in an isolated Git worktree. It records the base commit, sets file ownership and stop conditions, follows the repository's real checks, and preserves either a reviewable commit or an honest failure trail for the morning.

What you get

• A preflight covering repository state, instructions, test commands, and task boundaries
• A named branch and isolated worktree tied to an explicit base commit
• Time, iteration, and provider-budget limits set before work starts
• A loop that stops on repeated failures, stalled progress, secrets, or scope escape
• Targeted tests first, then the repository's broader verification where justified
• A complete diff and credential review before any success handoff
• A morning receipt with commit SHA, changed files, exact checks, elapsed effort, assumptions, and open gates
• Recoverable partial work when the task cannot safely finish

It never pushes, opens a pull request, merges, deploys, or silently upgrades to a paid provider. This is the narrow overnight lane for developers who want useful progress without surrendering review.

Built from operating experience with isolated agent worktrees, bounded watchdogs, deterministic gates, and the uncomfortable cases where an agent produced a clean commit but failed to exit correctly. It complements Agent Mission Control; it does not replace a multi-agent orchestrator.
