Use before you change a table, a column or a function, to see what it is built from, what depends on it, who reads it, which checks cover it, and the safe order of the change.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Impact The job: the answer to "if I change this, what breaks", before the change is made. Input: the table, the column or the function to change. ## Steps 1. Name the thing to change: a table, a column, a function or a file. 2. Upstream: everything it is built from, layer by layer. 3. Downstream: every table, view, report, test and job that reads it, found in the SQL and the code, never from memory. 4. The consumers: who queried the downstream tables in the last period, from the query logs, by role and team. 5. The checks and the tests that cover it, and the ones that will break. 6. The blast radius in numbers: tables, data products, consumers, queries, checks. 7. The safe order of the change: what to change first, what to rebuild, what to compare, and whom to tell. 8. Give the result as one web page, with the graph and the lists. ## Output One HTML file, like [references/impact.html](references/impact.html): the numbers on top, the graph with the thing to change lit, upstream and downstream, then the consumers, the checks and the safe order of the change. Read it for the layout before you write the page. ## Reads …

How to install
mdr add datawithbaraa/claude-code-data-engineering-skills/impact@sha256:6cf91b42360c4ad3The line at the top of this page pins the label git:20261029.2e2b6c2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
