It combines evidence-based planning, test-driven implementation, full documentation maintenance, deep code review, and architectural analysis into a team of specialists you can dispatch from Claude Code.\n\n## What this plugin does\n\nHan turns planning, implementation, review, and documentation work that would normally take a team into a set of deterministic skills you run from Claude Code. Each skill dispatches specialist agents (project managers, adversarial reviewers, investigators, architectural analysts, testing and security specialists) to do the judgment-heavy work, then folds their findings into an artifact you can trust.\n\nThe skills are designed to compose. You can plan a feature, then plan its implementation, then iterate on the plan, then build it test-first, then review the resulting code, then write the PR description. All through named skills that hand off to each other cleanly.\n\nRead [Concepts](./docs/concepts.md) for the skill-and-agent model that runs through the whole plugin.\n\n## Which path are you on?\n\n- **New to han?** → Start with [Concepts](./docs/concepts.md), then the [Quickstart](./docs/quickstart.md).\n- **Looking for a specific skill?** → [Skills Index](./docs/skills/README.md). 20 skills grouped by purpose.\n- **Looking for a specific agent?** → [Agents Index](./docs/agents/README.md). 22 agents grouped by role.\n- **Wondering how the agent swarms scale?** → [Sizing](./docs/sizing.md). The small / medium / large dispatch model used by `/architectural-analysis`, `/code-review`, `/gap-analysis`, `/iterative-plan-review`, `/plan-a-feature`, `/plan-implementation`, and `/research`.\n- **Wondering why a skill said \"YAGNI\"?** → [YAGNI](./docs/yagni.md). The evidence-based rule every planning, review, and architecture skill applies before committing items to an artifact.\n- **Writing or editing a skill or agent?** → [Contributing](./CONTRIBUTING.md).\n\n## Installation\n\nAdd the Test Double skills marketplace to Claude Code, then install the plugin:\n\n```\n/plugin marketplace add testdouble/han\n/plugin install han@han\n```\n\n## Documentation\n\n- [Concepts](./docs/concepts.md). Skill vs. agent, and how they compose. Read once before using the plugin.\n- [Quickstart](./docs/quickstart.md). Four paths for four common situations. Each path is a short sequence of skills.\n- [Skills Index](./docs/skills/README.md). All 20 skills, grouped by purpose.\n- [Agents Index](./docs/agents/README.md). All 22 agents, grouped by role.\n- [Sizing](./docs/sizing.md). The small / medium / large model that decides how many agents the swarming skills dispatch.\n- [YAGNI](./docs/yagni.md). The evidence-based \"You Aren't Gonna Need It\" rule every planning, review, and architecture skill applies.\n- [Contributing](./CONTRIBUTING.md). Adding or editing skills, agents, and documentation.\n- [Changelog](./CHANGELOG.md). What's new in each version of the plugin.\n\n## Maintenance and Support\n\n- **Maintenance horizon:** Indefinitely maintained, best-effort. No SLA.\n- **Project type:** Personal project, with some Test Double support\n- **How to report issues:** GitHub Issues, with expected best effort for response within 2 weeks.\n\nHan is an open source product of [Test Double](https://testdouble.com), and maintained by the following people:\n\n- [River Lynn Bailey](https://github.com/mxriverlynn): Creator, and primary maintainer\n\n## LEGAL NOTICES\n\nCopyright 2026 [Test Double, Inc](https://testdouble.com).
