What Rseng Lesson does

description: Record a lesson learned and draft its prevention artifact

Capture a lesson learned, following ${CLAUDE_PLUGIN_ROOT}/skills/rseng-lessons-learned/SKILL.md. The lesson is $ARGUMENTS if given, otherwise the most recent notable event in this session (a bug fixed, an approach abandoned, a review pattern).

Steps:

Write the entry: dated, tagged, blame-free - context, what happened, the lesson, in a few plain lines; append to LESSONS.md (create it if absent).
Route it
