Simplepowers

A lightweight skills library for Claude Code, Codex, and OpenCode. Guides agent work through a disciplined workflow — brainstorm, plan, implement, debug, review — without requiring worktrees, parallel agents, or any external infrastructure.

Simplepowers is a focused subset of superpowers, keeping only the skills that apply in every session and removing the advanced orchestration layer.

Skills

| Skill | Purpose | |-------|---------| | brainstorming | Turn requirements into a reviewed design spec before writing any code | | writing-plans | Convert a design spec into a bite-sized, executable implementation plan | | executing-plans | Load a written plan and work through it task by task with verification checkpoints | | test-driven-development | Write a failing test before every piece of production code | | systematic-debugging | Find the root cause before proposing any fix | | requesting-code-review | Review completed work against requirements and plan | | receiving-code-review | Evaluate incoming review feedback with technical rigour before acting | | verification-before-completion | Run evidence-producing commands before claiming anything is done | | using-simplepowers | Entry point — establishes skill rules and priority for the session |

Workflow

Skills chain together in a natural sequence:

brainstorming → writing-plans → executing-plans → verification-before-completion
                                      ↓
                         test-driven-development (at each task)
                         systematic-debugging    (when something fails)
                         requesting-code-review  (when a feature is complete)

Each skill enforces its own process. Skipping steps is explicitly called out as a rationalization and blocked.

Installation

Claude Code

Install from the Claude Code plugin registry:

/plugin install simplepowers

Or install from a local clone:

/plugin install /path/to/simplepowers

Skills load automatically. To establish the full skill ruleset at session start:

/using-simplepowers

Codex CLI

/plugins

Search for simplepowers and select Install Plugin.

Codex App

Click Plugins in the sidebar, find Simplepowers in the Coding section, and click +.

OpenCode

OpenCode discovers skills from .opencode/skills in the project root. Symlink this repo's skills/ directory there:

mkdir -p .opencode
ln -s /path/to/simplepowers/skills .opencode/skills

Intermediate files

Plans, specs, and notes produced during sessions are saved under the project root:

| Platform | Path | |----------|------| | Claude Code | .claude/simplepowers/ | | Codex | .codex/simplepowers/ | | OpenCode | .opencode/simplepowers/ |

Add these paths to .gitignore if you prefer not to commit them.

What simplepowers is not

• It does not manage git branches or pull requests
• It does not dispatch parallel subagents
• It does not require any server, browser, or external process

If you need multi-agent orchestration, git worktree isolation, or the skill authoring workflow, see superpowers.
