Claude Skills: Automate LinkedIn Posts with Reusable Instruction Packages
Create a skill folder with SKILL.md, define trigger phrases, add examples, and test it in Claude to automate LinkedIn post generation.
Build a skill for LinkedIn post generation: create .claude/skills/linkedin-post/SKILL.md, write trigger phrases, add examples, test in Claude, and enable in settings.
Summary
Claude Skills, also known as Agent Skills, let you package reusable instruction sets that fire automatically when Claude detects a matching task description. A skill lives in a folder with a SKILL.md file that starts with a YAML frontmatter defining the skill’s name and a concise description that serves as the trigger. The body of SKILL.md contains a playbook of steps, examples, and rules, while any lengthy style guides or API docs can be linked as separate files to keep token costs low through progressive disclosure. Skills can be globally available by placing them in ~/.claude/skills/, or project‑specific by dropping them into .claude/skills/<skill‑name>/.
The article shows how Ahrefs’ content marketer used a skill to turn blog posts into LinkedIn snippets automatically, eliminating the need to re‑prompt Claude each time. It explains how to write trigger phrases that match user intent, how to lock down side‑effect skills with disable-model-invocation: true, and how Claude Code ships with bundled skills such as /batch and /claude-api that can be leveraged immediately. The approach is designed to keep token usage minimal and to allow developers to iterate on the playbook without re‑loading large reference material.
