Checks every lookup in the open workbook for the faults that return a wrong row rather than an error: approximate match left on by default, duplicate keys on the lookup side, keys that exist in one table and not the other, mismatched types, and ranges that shift when rows are inserted. Changes nothing. Use when the user asks to check lookups, joins, references between tables, or why two sheets disagree.
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
# Lookup integrity check ## Purpose A lookup that fails loudly returns an error and gets fixed. A lookup that matches the wrong row returns a real value from a real record, and that value goes into a report. The skill examines every lookup in the workbook for the faults that produce a confident wrong answer, and reports them with the keys involved. ## When to use - The user asks to check lookups, joins, mappings or references between tables. - Two sheets that should agree do not, and the cause is not yet known. - Do not use to repair or rewrite lookups. This skill reports, the builder decides. ## Inputs 1. The open workbook (required). 2. Scope (optional): all lookups (default), or named sheets. 3. Key columns (optional): if the user names the columns that should act as keys, use them; otherwise infer and say what was inferred. ## Procedure 1. Find every lookup, in whatever form the workbook uses: direct lookup functions, index and match pairs, and conditional aggregations acting as lookups. 2. For each, record the lookup value, the table or range searched, the column or index returned, and the match mode as written. …

How to install
mdr add kesslernity/awesome-copilot-office-skills/lookup-integrity-check@sha256:ee525e851c9bc02bThe line at the top of this page pins the label git:20261024.a411dc2, 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.
