han

Planning-facing skills for the Han suite: specifying, planning, sequencing, breaking down, and stress-testing work before implementation. Home of plan-a-feature (build a feature specification from scratch through a relentless, evidence-based interview that walks the design tree), plan-implementation (turn a feature specification into an implementation plan through a project-manager-led team conversation), plan-a-phased-build (split a body of context into a sequence of independently demoable vertical-slice phases), plan-work-items (break a trusted implementation plan into independently-grabbable, atomic work items), and iterative-plan-review (stress-test an existing plan through multiple codebase-grounded review passes). Depends on han-core; bundled by the han meta-plugin.

Coding-facing skills for the Han suite: writing, reviewing, testing, investigating, and standardizing code. Home of the tdd skill, which drives a feature or behavior through a BDD-framed red-green-refactor loop with an enforced observed-failure gate, and the refactor skill, which restructures existing code without changing its behavior through a test-gated refactoring loop, plus code-review (comprehensive review of local changes), code-overview (a progressive-disclosure, understand-now overview of unfamiliar code or a PR's changes), architectural-analysis (module-level coupling, data flow, concurrency, risk, and SOLID assessment), test-planning (coverage-gap and edge-case test plans), investigate (evidence-based root-cause debugging), and coding-standard (creating and updating coding standards). Depends on han-core; bundled by the han meta-plugin.

Github specific extensions to the Han plugin for agentic planning and coding. Provides skills to post code reviews as PR comments, update a PR description with a consistent format, etc.

Guidance and tooling for building Claude Code skills and plugins. Carries the full body of skill-authoring, agent-authoring, and plugin-configuration guidance, and an init step that vendors that guidance into any repo as a path-scoped rule index so contributors get the right guidance loaded for the file they are editing. Standalone and opt-in: depends on nothing and is not bundled by the han meta-plugin.
