Agent Skills: reflect-solution

Summarize WHAT WAS SHIPPED in a Claude Code session as a self-contained HTML slide deck — the elevator pitch (problem, solution, decisions, artifacts, verification, gaps), not a play-by-play of tool calls or debugging detours. Defaults to the current in-context session; optionally accepts a session ID or JSONL path. Renders directly in the reflect aesthetic — no delegation. Use when the user invokes /reflect-solution or asks for a recap deck of what changed.
