ecc vs superpowers
Two of the top skills, plugins and rules, side by side: score, setup, license, activity and what each review found.
ecc
Skills, agents, hooks and rules that add a workflow to coding agents
superpowers
Skill library that enforces a plan-then-TDD workflow in coding agents

ecc
ECC installs a set of 68 agents, 293 skills, 94 legacy command shims, hooks, rules, memory and continuous-learning tooling into coding agents, aiming to enforce a plan, test, implement, review, verify loop. It ships as a Claude Code plugin (`ecc@ecc`) and the `ecc-universal` npm package, with guided setup for Claude Code, Codex and Kimi Code. It also bundles AgentShield, which scans prompts, hooks, MCP config, permissions and secrets.
Who it is for: Developers using Claude Code or Codex who want preset workflows
Strengths
- Guided installer with dry-run for Claude Code, Codex and Kimi Code
- Bundles AgentShield scanner for hooks, MCP config, permissions and secrets
- Large catalog: 68 agents, 293 skills, plus selectable rule packs by language
- MIT license; release 2026-10-01 and commit 2026-10-02 are recent
Weaknesses
- Full support is Claude Code only; other harnesses are capability-limited adapters
- Stacking install methods duplicates skills and hooks; reset steps are needed
- Claude plugins cannot ship rules, so those are copied manually
- ECC Pro GitHub App for private repos is paid, from $19/seat/month
- no GPU
- Docker + Compose
- Needs Node.js 18+, Git, Claude Code 2.1+ (for plugin setup)
superpowers
Superpowers is a set of composable skills plus a session-start bootstrap that makes a coding agent brainstorm a spec, write a task-level plan, and then execute it with red/green TDD and review between tasks. Execution can use a fresh subagent per task or run inline in one session. It installs as a plugin or extension for Claude Code, Codex, Cursor, Gemini CLI, Copilot CLI, OpenCode and several other harnesses.
Who it is for: Developers using coding agents who want a enforced plan, TDD and review workflow
Strengths
- Installs as a native plugin on about 15 agent harnesses
- Skills trigger automatically through a session-start bootstrap
- Includes a diagnosing-superpowers skill that reads session transcripts for debugging
- MIT licensed; skill behavior tests use a separate eval harness
Weaknesses
- Must be installed separately for each harness you use
- Contributions of new skills are generally not accepted
- Brainstorming visual companion sends version telemetry unless disabled by env var
- Enforced workflow adds planning and review overhead to small tasks
- no GPU
