testdoubleOfficial·37 Agent Skills Included

han

Evidence-based planning, code review, testing, and documentation workflows

Runs feature planning, test-driven coding, deep code review, bug investigation, and documentation through specialist sub-agents dispatched by slash commands. Replaces ad-hoc prompting with deterministic workflows that demand evidence, apply YAGNI, and adversarially validate every plan, review, and report. Publishes results directly to GitHub pull requests and issues, Jira, Linear, and Confluence, so solo engineers ship team-quality work faster.

Frequently Asked Questions

FAQPage Schema

How to install Han?▼

Run `npx skills add testdouble/han --all -g -y` in your terminal to install the full skill set globally.

What does Han do for solo developers?▼

It gives one engineer a full team's workflow: feature planning, test-driven implementation, adversarial code review, bug investigation, and documentation, each run as a named slash command that dispatches specialist sub-agents.

Can Han post reviews and tickets to GitHub, Jira, or Linear?▼

Yes. Dedicated skills post code reviews to pull requests, turn work-item files into GitHub issues, Jira tickets, or Linear issues, and publish plans and docs to Confluence.

Does Han work with Claude Code and Codex?▼

Yes. Every skill follows the standard SKILL.md format and ships with both Claude Code and Codex plugin manifests, so it runs in either environment.

Do I need to configure anything before using Han?▼

No. Most skills auto-discover your project's test commands, docs folders, and conventions, and optional `.han/config.md` files let you set defaults like output directories and swarm size.
