SKILL.md

Structured progress tracking for multi-session development work with durable handoff files.

Four core modes: start a new session with project orientation, checkpoint progress with WIP commits and learnings capture, resume from SESSION.md with git diff context, and wrap sessions with completeness checks

Automatically manages SESSION.md files (progress log, current position, blockers, resume instructions) and updates CLAUDE.md with discovered patterns and gotchas

Reads git history and status to detect changes since last checkpoint, enabling clean context handoff across conversation boundaries

Designed for multi-phase features and work at risk of context compaction; skip for quick single-file edits or single-session tasks
