What problem does it solve? Implementing a Spec or set of GitHub issues by hand often leads to skipped tests, work done on the wrong branch, and unreviewed merges. This Skill provides a guided, human-in-the-loop workflow that enforces test-first discipline, isolated worktrees, and review before landing. ## Core Features & Use Cases - Interactive Spec execution: Work through a Spec or issue set step by step with the agent guiding each slice, as the human-driven counterpart to the autonomous /afk fleet. - Test-first discipline: Invokes /tdd at pre-agreed seams, requiring a failing test before any implementation code, with typechecking after every cycle. - Safe worktree workflow: All work happens in a dedicated .red/tmp/worktrees/manual/<slug> worktree, never on the primary branch, and lands via /retake after /code-review passes. - Use Case: You have a Spec broken into GitHub issues and want to implement it yourself with agent guidance — the Skill walks you through scoping, TDD cycles, full test suite validation, code review, and landing the branch. ## Quick Start Ask the agent to implement the current Spec interactively, starting by agreeing the scope and breaking it into issues with /to-tickets.
