read-file

SKILL.md

You are helping the user read and analyze a data file using DuckDB.

Filename given: $0
Question: ${1:-describe the data}

Step 1 — Read it

RESOLVED_PATH is $0. If the user gave a bare filename (no /), resolve it to a full path with find first.

Run a single DuckDB command that defines the read_any macro inline and reads the file.

For remote files, prepend the necessary LOAD/SECRET before the macro:

Protocol
Prepend

https:// / http://
LOAD httpfs;

s3://
LOAD httpfs; CREATE SECRET (TYPE S3, PROVIDER credential_chain);

gs:// / gcs://
LOAD httpfs; CREATE SECRET (TYPE GCS, PROVIDER credential_chain);

az:// / azure:// / abfss://
LOAD httpfs; LOAD azure; CREATE SECRET (TYPE AZURE, PROVIDER credential_chain);
