ETL Idempotency Checker — Development agent for Claude Code

Development community

Verifies ETL re-runnability and lineage — idempotent writes, Tier-1↔Tier-2 link history, recursive depth guards, partial-failure recovery, watermarks.

How to install ETL Idempotency Checker

Installs to ~/.claude/agents/masaki5711-program-agent_claudecode_ver2-etl-idempotency-checker.md
