I never really dug into skill libraries for open claw because I always thought they were too risky and not specialized enough for what I wanted to do.
It's trivial to create broad skills for your agent. If I wanted to create an ad copywriting skill:
• Prompt agent to use exa, grok and perplexity to gather all the top publishings, threads on copy writing that converts
• Feed agent a longer publications on writing ad copy
• Set brand values, tone of voice, general parameters (don't swear, etc.)
But this is too broad. Where it becomes valuable to someone is if they implement a feedback loop with data specific to their use case
• Write ads and propose to human
• Take note of what human approved/denied and any possible reasons why
• Run ads
• Track live conversion
• Notice patterns
• Feed patterns back into step 1
