SkillBill: A Kotlin Orchestrator That Runs AI Coding Agents Through 7 Enforced Phases
prakersh · reddit · 2026-09-21
Frustrated by accumulating 'skills' nobody remembers to invoke, a developer built SkillBill (MIT, skillbill.dev), a Kotlin orchestrator enforcing 7 phases: pre-planning, planning, implementation, audit (against acceptance criteria), review, validation, and PR. Phase transitions are controlled by the Kotlin runtime, not prompts, with execution state in a local DB so agents can resume mid-task. The author ran a 20-subtask repo-wide refactor for 20 hours without token or context worries. After 6 months: near-zero QA returns, 0-1 review comments per PR. Includes IntelliJ/VS Code progress plugins; CodeGraph integration in progress.
