implement-worktree

To implement a development plan in an isolated Git worktree, this Skill automates worktree creation, environment setup, and phased coding based on your plan file. It ensures changes remain contained and verifiable before merging into your main codebase.

Executing phased code implementation without affecting your main branch is best handled by creating an isolated Git worktree. This approach fences scope for each phase, runs pre-commit checks, and executes a full test suite to verify changes independently.

Yes, you can run pre-commit checks and full test suites automatically within a Git worktree. The implementation process includes automated verification steps that execute tests and validate code quality before final rebasing for merge readiness.

Yes, you need a detailed plan file to start automated worktree implementation. The Skill executes multi-part plans phase by phase, requiring a defined plan document to fence scope, guide subagent-driven system understanding, and structure the coding workflow.

Subagent-driven system understanding works by deploying subagents to explore the codebase thoroughly before coding begins. This mechanism ensures the implementation plan is accurately mapped to the existing system architecture within the isolated worktree environment.

You should reset the code index after completing worktree implementation to clear temporary state and ensure the main repository index remains clean. This post-completion step finalizes the isolated changes and prepares the rebased commits for review.
