Summary

If you're building custom Claude Code workflows, you'll eventually need to package your own skills, and this walks you through the whole setup. It covers the required YAML frontmatter (name and description fields), progressive disclosure structure, and directory organization that Claude expects. The source shows you exactly where files go (top-level only, no nesting), how to write descriptions that help Claude know when to invoke your skill, and what a complete skill package looks like with scripts and templates. Think of it as the spec and scaffolding tool in one. Most useful when you've hit the limits of existing skills and need something purpose-built for your team's workflow.

sponsio

sponsiolabs/sponsio

Install, observe, tune, enforce, and periodically refresh Sponsio — a runtime contract layer for LLM agents that blocks unsafe tool calls and scores output quality against declared rules. Use when the user wants to set up / add / install Sponsio, add guardrails or runtime safety to an LLM agent, generate or refine a sponsio.yaml, audit tool configurations for risks (data leaks, unguarded writes, missing confirmations), explain or review existing contracts, check what Sponsio would have blocked (`sponsio report`), refresh the contract library from recent traces (`sponsio refresh`), move from observe to enforce mode, or debug why a contract is (or isn't) firing. Triggers on phrases like "set up sponsio", "add sponsio", "install sponsio", "add guardrails", "monitor my agent", "harden my agent", "audit my agent", "generate contracts", "explain my sponsio.yaml", "sponsio report", "refresh contracts", "update my sponsio.yaml from traces", "flip to enforce", "false positive", "why is this rule firing".

ppt-agent

sunbigfly/ppt-agent-skills

专业 PPT 演示文稿全流程 AI 生成助手。模拟顶级 PPT 设计公司的完整工作流(需求调研到资料搜集到大纲策划到策划稿到设计稿),输出高质量 HTML 格式演示文稿。当用户提到制作 PPT、做演示文稿、做 slides、做幻灯片、做汇报材料、做培训课件、做路演 deck、做产品介绍页面时触发此技能。即使用户只说"帮我做个关于 X 的介绍"或"我要给老板汇报 Y",只要暗示需要结构化的多页演示内容,都应该触发。也适用于用户说"帮我把这篇文档做成 PPT"、"把这个主题做成演示"等需要将内容转化为演示格式的场景。英文场景同样适用:"make a presentation about..."、"create slides for..."、"build a pitch deck"、"I need a keynote for..."。隐式意图也应触发:"帮我把这个数据可视化一下给老板看"、"我需要一份能拿去路演的东西"、"把这个报告做得好看点能展示"、"beautify my existing PPT"、"redesign these slides"。改善或美化现有 PPT 也属于此技能范畴。
