# STEP 0: STALE-CLONE SELF-CHECK — RUN BEFORE READING BELOW Before reading anything else in this file, check whether you loaded SKILL.md from the one known stale-clone location: Claude Code's marketplaces directory. **Run this check:** ```bash CLAUDE_CACHE_LATEST=$(find "$HOME/.claude/plugins/cache/last30days-skill/last30days" -mindepth 1 -maxdepth 1 -type d 2>/dev/null | sort -V | tail -1) # Two cache layouts ship in the wild — nested ({version}/skills/last30days/SKILL.md) # and flat ({version}/SKILL.md).
