lineage skillA

lineage is agent-read markdown (skill) from harnessprotocol/harness-kit: Use when user invokes /lineage with a column name (optionally qualified with table/schema). Also triggers on "trace this column", "where does X come from", "what reads from Y table". Traces column-level data lineage through SQL, Kafka, Spark, JDBC, and ORM codebases. Produces a structured lineage path with confidence ratings and an SVG or ASCII diagram. Do NOT use for general code explanation — use /explain instead..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add harnessprotocol/harness-kit/lineage@git:20260316.376a192
Exact content
mdr add harnessprotocol/harness-kit/lineage@sha256:cce911f62c3b71a8

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
