sawzhang-skills

Plug-and-play skills that make Claude Code smarter — MCP review, Twitter research, auto-iteration, CCA exam prep, and Harness Engineering workflows.

即装即用的 Claude Code 技能包 — MCP 工具审查、Twitter 调研、自动迭代优化、CCA 认证备考、Harness Engineering 全流程开发。

Why This Exists

Claude Code is a general-purpose agent. But for specific workflows — reviewing MCP tool designs, researching Twitter trends, or studying for the CCA exam — you need specialized instructions that encode domain expertise. That's what skills are: reusable prompt packages that turn Claude into a domain specialist.

Adding a New Skill

1. Create a directory under plugins/sawzhang-skills/skills/
2. Add a SKILL.md with YAML frontmatter (allowed-tools must use standard tool names only)
3. Bump plugins/sawzhang-skills/.claude-plugin/plugin.json version (new skill → minor bump)
