s3-query-skill

s3-query-skill is a SQL analytics & reporting skill for AI agents, published by OpenLinkSoftware in the ai-agent-skills repository on GitHub. Skillspace rates s3-query-skill C (77/100) and it passed the safety scan; the rating is based on static analysis only.

Client-side S3 API access for querying data directly at S3 and S3-compatible endpoints — AWS S3 public/private buckets, Hugging Face Storage Buckets (s3.hf.co), Cloudflare R2, MinIO, Wasabi, Backblaze B2 — without a full download. Uses DuckDB's httpfs extension to run SQL directly against remote Parquet/CSV/JSON/ND-JSON objects (e.g. querying the Common Crawl columnar index or a Hugging Face-hosted crawl index in place), plus AWS CLI/boto3 for object-level list/head/get/put and rclone for bulk cross-store copy. Triggers on phrases like "query data in an S3 bucket", "query an S3 API endpoint", "read a Parquet file from S3 without downloading it", "list objects in this bucket", "query the Common Crawl index", "connect to a Hugging Face Storage Bucket via S3", or any request to read/query/list/copy data at an `s3://` URI or S3-compatible HTTPS endpoint.
