Superpowers
Framework by Jesse Vincent (Perl veteran, Keyboardio co-founder): enforced 7-phase workflow (Brainstorm → Spec → Plan → TDD → Subagent Dev → Review → Finalize). TDD mandatory, deletes code written before tests exist. Compatible with Claude Code, Cursor, Codex, Gemini CLI. Official Anthropic marketplace since Jan 2026. Enables multi-hour autonomous dev sessions.
Strengths
- Enforced 7-phase workflow: Brainstorm → Spec → Plan → TDD → Dev → Review → Finalize
- Mandatory TDD: Claude deletes code written before tests, zero shortcut possible
- Native parallel sub-agents, multiple Claudes in parallel on the same problem
- 259.3k GitHub stars, official Anthropic marketplace since Jan 2026, widely adopted
Limitations
- Redundant with GSD v2 for autonomous orchestration, choose one or the other
- 7-phase workflow overkill for tasks under one hour
- Less persistent traceability than GSD: no ROADMAP.md or cross-session state machine
Best for
- Developers discovering Claude Code wanting a ready-made opinionated workflow
- Complex features requiring a brainstorm phase and formal spec before coding
- Teams wanting to enforce TDD through their AI assistant, without compromise
