Installation

Installation

Install 8-habit-ai-dev through the plugin marketplace for your agent runtime. The package is markdown-only: no dependency install, build step, or application service is required.

Note

Claude Code and Codex use different package surfaces. Both load the same skills/ content; Claude hook feature parity is not assumed. If Codex invokes the package SessionStart hook, the hook returns Codex-compatible JSON.

Claude Code

claude plugin marketplace add pitimon/8-habit-ai-dev
claude plugin install 8-habit-ai-dev@pitimon-8-habit-ai-dev

Start a new Claude Code session after installation. The session banner should include 8-Habit AI Dev Active and a short 7-step workflow reminder.

Verify:

claude plugin list

Update:

claude plugin update 8-habit-ai-dev@pitimon-8-habit-ai-dev

Uninstall:

claude plugin uninstall 8-habit-ai-dev@pitimon-8-habit-ai-dev

Codex

codex plugin marketplace add pitimon/8-habit-ai-dev
codex plugin add 8-habit-ai-dev@pitimon-8-habit-ai-dev

Verify:

codex plugin list

Codex should use AGENTS.md as the operating entrypoint, then route user intent through skills/RESOLVER.md to the relevant skills/<name>/SKILL.md.

Codex currently has no codex plugin update command. Refresh the configured Git marketplace snapshot, then reinstall the plugin from that refreshed snapshot:

codex plugin marketplace upgrade pitimon-8-habit-ai-dev
codex plugin list
codex plugin remove 8-habit-ai-dev@pitimon-8-habit-ai-dev
codex plugin add 8-habit-ai-dev@pitimon-8-habit-ai-dev
codex plugin list

Use codex plugin marketplace list if you need to confirm the configured marketplace name.
