Files API Integration
For large datasets and data files, the Files API can ingest CSVs, JSON, Parquet, and other formats directly — avoiding token limits for bulk data analysis. Use data-ingestion from ccc-research for document-scale inputs.

When to invoke this skill
Example 1
- user: design an ETL pipeline to sync our Postgres data to a data warehouse
- assistant: Loads ccc-data and routes to data-pipeline for Airflow/dbt/Dagster pipeline design with incremental loads.
Example 2
- user: my SQL queries are slow — optimize them
- assistant: Loads ccc-data and routes to sql-optimization for query analysis, index recommendations, and execution plan review.
Example 3
- user: add semantic search to our product catalog
- assistant: Loads ccc-data and routes to vector-search for pgvector/Pinecone/Qdrant setup with embedding pipeline.
