A collection of guidance for test-driven development (TDD), debugging, teamwork, and other coding practices. TDD means writing tests before the code they check.

Use it when developing with TDD, investigating bugs, or coordinating coding work.

It gives an agent structured practices to follow instead of approaching testing and debugging from scratch.

superpowers — Plugin for Gemini CLI by obra

About the project

Superpowers is a software development methodology for coding agents that guides work from clarifying requirements through design, planning, implementation, testing, and review. It is for developers who want agents to follow a structured, test-focused process using composable skills and subagents.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

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 6d ago.

The scan reads gemini-extension.json. This mod also ships 5 executable files (scripts/bump-version.sh, scripts/lint-shell.sh, scripts/package-codex-plugin.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What ships with it

8 files beside gemini-extension.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
