Function: Glossary Manager
The glossary is where governance programs quietly rot: terms collide, definitions drift, and orphaned entries accumulate until nobody trusts it. This agent proposes terms from the technical layer, builds the taxonomy, and continuously scans for the decay.

Eight dimensions across every column, five of them shown here. Nothing is written; this is a read.
4,812 rows · 8 columns · 2 columns flagged · 2 for review
Table and column descriptions written from the profile and the column context. Every one is a draft until a steward accepts it.
1 table + 4 columns described · awaiting steward
Seven rules proposed from the profile. Each carries the proof that produced it, so approval is a judgment call rather than a leap of faith.
customer_id, Must not be null
Completeness
0.0% null across 4,812 rows. Already clean, worth enforcing as a hard constraint before it drifts.
customer_id, Must be unique
Uniqueness
4,812 distinct values across 4,812 rows. Uniqueness holds today; the rule locks it.
tax_id, Must match the tax ID format
Validity
97.2% of non-null values match the pattern. 118 do not, mostly nine-digit strings missing the hyphen.
tax_id, Null rate must stay under 5%
Completeness
12.2% null against a 5% domain threshold. 587 rows. This is the largest single rule failure in the table.
email, Must be a parseable email address
Validity
4,359 of 4,422 non-null values parse. 63 do not: trailing semicolons and two addresses in one field.
status, Must be one of the accepted values
Validity
Exactly 4 distinct values observed, all within the expected set. Cardinality of 4 on 4,812 rows reads as a controlled vocabulary.
country_code, Must exist in the country reference set
Consistency
47 distinct codes. Two (XK, AN) are absent from ref.country, affecting 12 rows. Neither is a current ISO 3166-1 code.

Nothing reaches production without this step. Uncheck anything you would not stand behind. In the real product, the SQL is editable too.

People adjudicate once. The agent propagates the decision.
Writes the descriptions nobody ever writes, for every table and every column.
Business glossary, domains and ownership as code, inside open-source DataHub.
Turns physical schemas back into models people can reason about.
Discovery is read-only, takes five days, and costs nothing. We assess your environment and tell you honestly whether this agent is worth your time.
