| Field | superpowersgithub.com | karpathy-skillsgithub.com | ECC (Everything Claude Code)github.com |
|---|---|---|---|
| What it is | 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. | 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. | The largest harness here by volume: 68 agents, 285 skills, 94 slash commands, a security scanner for prompts and configs, session memory, and a browser-based Plan Canvas. Coordinates a fixed lifecycle: plan → test → implement → review → verify → remember → improve. ~241k stars. |

| Why builders pick it | 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. | 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. | Powerful but maximal — installing this and superpowers and gstack at once means three competing methodologies. Pick one harness. |
