Superpowers — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Superpowers (Plugin) and scored it 65/100 (yellow). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 3 high-severity and 5 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Superpowers is a complete software development methodology for your coding agents, built on top of a set of composable skills and some initial instructions that make sure your agent uses them.
We're hiring someone to help out full time with Superpowers community and code work. You can read about the job at https://primeradiant.com/jobs/superpowers-community-engineer/ If this sounds like someone you know, definitely send them our way.
Give your agent Superpowers: Claude Code, Antigravity, Codex App, Codex CLI, Cursor, Factory Droid, Gemini CLI, GitHub Copilot CLI, Kimi Code, OpenCode, Pi.
It starts from the moment you fire up your coding agent. As soon as it sees that you're building something, it doesn't just jump into trying to write code. Instead, it steps back and asks you what you're really trying to do.
Once it's teased a spec out of the conversation, it shows it to you in chunks short enough to actually read and digest.
After you've signed off on the design, your agent puts together an implementation plan that's clear enough for an enthusiastic junior engineer with poor taste, no judgement, no project context, and an aversion to testing to follow. It emphasizes true red/green TDD, YAGNI (You Aren't Gonna Need It), and DRY.
Next up, once you say "go", it launches a subagent-driven-development process, having agents work through each engineering task, inspecting and reviewing their work, and continuing forward. It's not uncommon for your agent to work autonomously for a couple hours at a time without deviating from the plan you put together.
There's a bunch more to it, but that's the core of the system. And because the skills trigger automatically, you don't need to do anything special. Your coding agent just has Superpowers.
If you're using Superpowers in enterprise and could benefit from commercial support, additional tooling, or managed spending, please don't hesitate to drop us a line at [email protected].
Installation differs by harness. If you use more than one, install Superpowers separately for each one.
Superpowers is available via the official Claude plugin marketplace
#### Official Marketplace
/plugin install superpowers@claude-plugins-official#### Superpowers Marketplace
The Superpowers marketplace provides Superpowers and some other related plugins for Claude Code.
/plugin marketplace add obra/superpowers-marketplace /plugin install superpowers@superpowers-marketplaceInstall Superpowers as a plugin from this repository:
agy plugin install https://github.com/obra/superpowersAntigravity runs the plugin's session-start hook, so Superpowers is active from the first message. Reinstall with the same command to update.

Fetch and follow instructions from https://raw.githubusercontent.com/obra/superpowers/refs/heads/main/.opencode/INSTALL.mdInstall Superpowers as a Pi package from this repository:
pi install git:github.com/obra/superpowersFor local development, run Pi with this checkout loaded as a temporary package:
pi -e /path/to/superpowersThe Pi package loads the Superpowers skills and a small extension that injects the using-superpowers bootstrap at session startup and again after compaction. Pi has native skills, so no compatibility Skill tool is required. Subagent and task-list tools remain optional Pi companion packages.
The agent checks for relevant skills before any task. Mandatory workflows, not suggestions.

The general contribution process for Superpowers is below. Keep in mind that we don't generally accept contributions of new skills and that any updates to skills must work across all of the coding agents we support.
writing-skills skill for creating and testing new and modified skillsSkill-behavior tests use the drill eval harness from superpowers-evals, cloned into evals/ — see evals/README.md for setup. Plugin-infrastructure tests live at tests/ and run via the relevant run-*.sh or npm test.
See skills/writing-skills/SKILL.md for the complete guide.
Superpowers updates are somewhat coding-agent dependent, but are often automatic.

Because skills and plugins don't provide any feedback to creators, we have no idea how many of you are using Superpowers. By default, the Prime Radiant logo on brainstorming's optional visual companion feature is loaded from our website. It includes the version of Superpowers in use. It does not include any details about your project, prompt, or coding agent. We don't see your clicks or anything about what you're building. This helps us have a rough idea of how many folks are using Superpowers and which version of Superpowers they're using. It's 100% optional. To disable this, set the environment variable SUPERPOWERS_DISABLE_TELEMETRY to any true value. Superpowers also honors Claude Code's DISABLE_TELEMETRY and CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC opt-outs.
Superpowers is built by Jesse Vincent and the rest of the folks at Prime Radiant.
