What this skill does

Cross-domain pattern analysis and strategic reflection for weekly review Check agentmode in 00-inbox/MY-PROFILE.md frontmatter:* - If agentmode: team — delegate domain-specific analysis to sub-agents (e.g., one for personal patterns, one for professional review, one per active project). Each agent scans relevant braindumps/briefs and returns insights. Combine into the weekly synthesis. - If agentmode: solo (default) — handle all scanning and analysis directly in the conversation. No delegation.
