What problem does it solve? Delegating coding work to an external CLI agent risks unbounded runs, leaked prompts, dirty repositories, and orphaned processes. This Skill wraps the Grok Build CLI in a hardened runner so Kimi can hand off implementation, debugging, review, research, and testing tasks with enforced deadlines, isolated Git worktrees, and verified completion. ## Core Features & Use Cases - Hardened execution wrapper: scripts/grok-run.sh enforces prompt-file privacy (mode 600), wall-clock deadlines, turn caps, output size limits, heartbeats, and process-group cleanup with a watchdog. - Isolated write modes: Run read-only reviews, create unique wrapper-managed Git worktrees per task, or write into an existing linked worktree with duplicate-writer locking. - Performance profiles: Choose safe (no memory/subagents, 20 turns, 30 minutes) for small reviews or heavy (native capabilities, 40 turns, 60 minutes) for implementation and research. - Verified acceptance: Runs are accepted only on zero exit, matching session ID, validated EndTurn JSON, and no surviving descendant processes. - Use Case: Ask Kimi to fix a bug in a feature branch; Kimi writes a standalone prompt file, launches one bounded Grok worker in a fresh worktree, inspects the resulting diff, runs independent tests, and merges only verified changes. ## Quick Start Ask Kimi to delegate a specific coding task to Grok, for example: "Delegate to Grok the implementation of input validation in src/api/handler.ts on a new worktree, then verify the diff and run the test suite."
