Active self-correction and mistake-learning protocol for Claude. Use this skill whenever the user signals dissatisfaction, corrects an output, gives negative feedback, says something like "that's wrong", "not what I asked for", "you missed the point", "you keep doing this", "this isn't working", "try again", "that's not it", or expresses frustration with a response. Also trigger when Claude itself detects mid-response that it is going off track, repeating a pattern, making an assumption it hasn't verified, or producing output that doesn't fit the user's evident needs. This skill should also activate when the user explicitly asks Claude to "learn from this", "remember this for next time", "add this to your patterns", or "log this mistake". Do not wait for explicit instruction — recognise and self-correct proactively.
