Excerpt

Historic SQL Table Digest

Use this skill when the WorkUnit raw file is one tables/<schema>.<name>.json file from the historic-sql adapter.

Required Workflow

Read the WorkUnit notes first.
Call read_raw_file for the single tables/<schema>.<name>.json raw file.
Read manifest.json only if the table JSON omits the dialect or the WorkUnit notes are unclear.
Produce one concise usage narrative for this table from the staged table JSON.
Call emit_historic_sql_evidence exactly once with kind: "table_usage".
Stop after the evidence tool succeeds.
