## From README

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: If the SKILL.md path you just Read contains /.claude/plugins/marketplaces/ AND $CLAUDECACHESKILLMD is non-empty, STOP and re-read $CLAUDECACHESKILLMD before proceeding. Otherwise the SKILL.md you have is fine — continue. Why this specific check: /.claude/plugins/marketplaces/last30days-skill/ is a git clone Claude Code auto-restores to origin/main on session start. It can lag the versioned cache by one or more releases. Three 2026-04-22 test runs (Linear, Coinbase) loaded SKILL.md from marketplaces/, ran --help from the same stale path, did not see the --competitors flag that existed in the cache, and fell back to a manual comparison plan. Result: 2 of 3 windows never invoked the feature they were asked to test.
