|---|---|---|---|
| What it is | A ruleset premised on 'the best code is code you never wrote'. Applies a seven-rung decision ladder forcing the agent to exhaust stdlib, existing project code and dependencies before writing anything new. Repo claims ~54% less code, 20% cheaper, 27% faster. ~104k stars. | A ~65-line CLAUDE.md built around four LLM coding failure modes Karpathy identified. Adds no tools — it changes how the agent decides: surface assumptions before coding, refuse speculative abstraction, keep diffs scoped, define a verifiable stopping condition. ~203k stars. | An agentic skills framework by Jesse Vincent that imposes a full development workflow: a Socratic brainstorming phase before any code is written, enforced RED-GREEN-REFACTOR TDD, subagent-driven parallel execution, systematic debugging and worktree management. ~272k stars. |

| Why builders pick it | Directly relevant to a Lovable project, where the failure mode is Claude re-implementing a component that already exists three folders over. Also ships review, audit and debt-tracking commands. | Cheapest quality win on the entire list. One file, no install, works alongside everything else. 'Surgical Changes' alone stops the drive-by refactors that break a working layout while fixing something unrelated. | The brainstorming phase is the part that matters for a build — it forces the requirements conversation (what is an issue? how does the archive paginate?) before Claude starts generating components you will throw away. |
