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.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'lineage' ] || [ -L ~/.agents/skills/'lineage' ]; then echo 'A skill folder named lineage already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/harnessprotocol/harness-kit' "$d" && git -C "$d" checkout --quiet '4094970dee9a31be7b899126aca1cd4256f57ca8' -- 'plugins/lineage/skills/lineage' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/lineage/skills/lineage' ~/.agents/skills/'lineage' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'lineage' ~/.claude/skills/'lineage' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
