AZC=~/.claude/skills/azure-cost-duckdb/scripts/azure_cost_duckdb.py

Gotchas And Troubleshooting
sync --dry-runfirst;--patternmatches container paths.sync --latest-runfor month folders with snapshots.validateafter large CSV downloads; row counts should match manifests.- Overwrite a bad partition:
sync --pattern <file>.csv;--no-overwritewon't resume. schemafirst; export column names vary.- Group by the derived
worker_pool_id(both tag spellings); absent-from-data may be unbilled, not free — see duckdb-queries.md, azure-exports.md. - Current periods can be rerated; refresh the current month.
- DuckDB locks a
.duckdbfile per process. - Do not commit
raw/,.duckdb, keys, tokens, or real config.
