This looks like a legitimate self-improvement skill, but it needs review because it can persist conversation-derived learnings and promote them into future agent context without strong approval or redaction controls.
Install only if you want the agent to keep persistent local learning notes. Before enabling hooks or global configuration, review the scripts and decide whether every-prompt reminders are acceptable. Do not let the agent store secrets, tokens, customer data, raw transcripts, or private error output in .learnings or promoted instruction files; manually review and sanitize anything before it is promoted into future agent context.
