Free Skill Library — 108 Agent Skills in SKILL.md format
Free Skill Library
108 complete Agent Skills in the open SKILL.md format. Every one has a real trigger condition, a workflow, documented failure modes and success criteria. Built for agents that run against real work, not for screenshots.
Gotchas and evaluation by default
Most public skills skip the two sections that decide whether an agent gets it right. Every file here names concrete failure modes and states what correct output looks like.
Descriptions that actually fire
Each description is written as an activation condition, starting with the situation rather than the topic, plus an explicit exclusion so neighbouring skills stop fighting.
Lean bodies, progressive disclosure
Name and description stay loaded. The full instructions load only when the skill fires. Nothing here bloats your context for the turns it is not needed.
Finished, not sketched
No stubs, no placeholders, no coming soon. Every file is written end to end against the failure modes that break this class of task, and you can drop it in today.
Free skills are single-purpose
- One file, one job, no state carried between runs
- No router, no sub-skills, no handoffs
- You decide when to fire them and in what order
- Built for a task you do often and want done consistently
OS Brains are systems
- An orchestrator plus ten specialists that route between each other
- Carries context across a whole engagement, not one prompt
- Covers a function end to end rather than a single task
- THE ARCHITECT builds new brains to your own operating model
