Autonomous Dev Kit

Autonomous Dev Kit is a complete software development workflow for your coding agents, built on top of a set of composable "skills" and some initial instructions that make sure your agent uses them.

How it works

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. In capable hosts, agents can work autonomously for long stretches 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 Autonomous Dev Kit.

Autonomous Dev Kit originated as a fork of Jesse Vincent's Superpowers repo.

Installation

Note: Installation differs by platform. Claude Code or Cursor have built-in plugin marketplaces. Codex can use the open skills CLI (npx skills add) or manual setup. OpenCode currently uses manual setup.

Claude Code (via Plugin Marketplace)

If you have the old superpowers plugin installed, uninstall it first before installing autodev:

# 1. Remove existing superpowers plugin (if installed)
/plugin uninstall superpowers

# 2. Remove the old marketplace (if registered)
/plugin marketplace remove superpowers-marketplace

# 3. Restart Claude Code to apply removals
/exit

Then in a fresh session, add the GoCodeAlone marketplace and install:

# 4. Register the GoCodeAlone marketplace
/plugin marketplace add GoCodeAlone/autodev-marketplace

# 5. Install the plugin
/plugin install autodev@autodev-marketplace

Alternatively, install the skills directly with the open Skills CLI:

npx skills add GoCodeAlone/autonomous-dev-kit -a claude-code --skill '*' -y

For user/global install:

npx skills add GoCodeAlone/autonomous-dev-kit -a claude-code --skill '*' -g -y

Cursor (via Plugin Marketplace)

In Cursor Agent chat, install from marketplace:

/plugin-add autodev

Codex

From your project root, install the skills with the open Skills CLI:

npx skills add GoCodeAlone/autonomous-dev-kit -a codex --skill '*' -y

For user/global install instead of project-local install:

npx skills add GoCodeAlone/autonomous-dev-kit -a codex --skill '*' -g -y

Then restart Codex so it discovers the skills.

The Skills CLI path installs SKILL.md files only. It does not install the Codex plugin wrapper, hooks, plugin trust state, or marketplace config. For the full Codex plugin install, use Codex's native plugin commands:

codex plugin marketplace add GoCodeAlone/autodev-marketplace
codex plugin add autodev@autodev-marketplace

To remove the old plugin first:

codex plugin remove superpowers@superpowers-marketplace
codex plugin marketplace remove superpowers-marketplace

Manual fallback: tell Codex:

Fetch and follow instructions from https://raw.githubusercontent.com/GoCodeAlone/autonomous-dev-kit/refs/heads/main/.codex/INSTALL.md

Detailed docs: docs/README.codex.md

OpenCode

Tell OpenCode:

Fetch and follow instructions from https://raw.githubusercontent.com/GoCodeAlone/autonomous-dev-kit/refs/heads/main/.opencode/INSTALL.md

Detailed docs: docs/README.opencode.md

Verify Installation

Start a new session in your chosen platform and ask for something that should trigger a skill (for example, "help me plan this feature" or "let's debug this issue"). The agent should automatically invoke the relevant autodev skill.

Cross-LLM Compatibility

Autonomous Dev Kit skills run on any host that supports the SKILL.md format. Host-specific tools (like Agent Teams) are conditioned with <host: claude-code> blocks so other hosts skip them gracefully.
