I built a tool. It scaffolds a Claude Code agent harness into any project.
A harness is the system that lets an AI coding agent produce correct, high-quality code consistently. It has four parts:
Guidance: CLAUDE.md and rules in .claude/rules/ that shape what the agent writes.
Guardrails: automated checks (lint, tests, build) the agent runs.
Flywheel: review feedback updates a rule file. The next conversation starts smarter.
Workflows: agents, commands, and skills under .claude/ that turn institutional knowledge into runnable procedures.
sellier ships a generic, slim version of all four. You run it once, then run a Claude command to fill in the placeholders.
