superpowers

superpowers is a plugin for Claude Code from zernie/vigiles. Its manifest loads nothing; the 2 skills it bundles cost 38 tokens per session together, scanned A, a copy of superpowers, MIT.

A library of coding practices for Claude Code, covering test-driven development (writing tests before code), debugging, and working with others.

In plain words
What is it for?
Use it when building features with tests, tracking down bugs, or coordinating coding work.
Why use it?
It gives the agent repeatable ways to plan, test, and investigate code instead of relying on ad hoc steps.

Security

Grade A, and why

superpowers scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to superpowers — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it installs

The manifest is a name and a version. 2 skills travel with it, and installing the plugin installs all of them — 38 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
