Extract reusable patterns, architectural decisions, and pitfalls from completed work
into .feature-radar/specs/. Captures the "why" behind choices so future sessions build
on past experience. MUST use this skill when the user reflects on what worked or didn't,
wants to record a decision or pattern for future use, or hit a dead end worth documenting.
Use when the user asks to remember, document, or extract lessons from recent work.
Do NOT use for recording external observations — that's feature-radar-ref's job.
Do NOT use for archiving completed features — that's feature-radar-archive's job.
