Agents without skills are demos. Skills are the reusable, replayable units of work that make agents useful across your real day-to-day tools.
Try SkillForge free What is SKILL.md?An agent is a runtime — a loop that reasons and acts. A skill is a specific capability it can invoke: "reconcile QuickBooks invoices", "triage GitHub issues", "onboard a new hire". Without skills, agents drift. With skills, they compound.
"Book a meeting room" is a skill. The agent is the thing that decides when to book, handles the conversation, and recovers from errors; the skill is the precise, repeatable procedure for how to book — open the calendar tool, pick the room, set the time, confirm. Give an agent good skills and it stops improvising the mechanical parts and gets them right every time.
Traditionally, engineers write them. But the fastest path is to record what you already do — SkillForge watches your screen recording and generates a portable SKILL.md that any agent runtime can replay.
Record your workflow → SkillForge extracts a SKILL.md → drop it into any agent → the agent replays it. Free for anyone getting started.

What is the difference between an AI agent and an agent skill?
An agent is the reasoning runtime that decides what to do; a skill is a specific, repeatable procedure it can execute. Agents without skills tend to drift; skills make behavior reliable.
Do I need to code to create an agent skill?
No. With SkillForge you record the task on screen and it generates a SKILL.md — a portable skill file — automatically.
Which agent frameworks can use these skills?
Claude Skills, autogen, crewAI, browser-use, langchain, and Gemini-based agents can all read a SKILL.md.
