asking your AI "what was our revenue last month" usually gets you a wrong SQL query
NVIDIA just released the fix
it's called Auto Ontology
it reads your database and builds a dictionary of business terms: what "revenue" means, which tables connect, where each number comes from
your agent checks that dictionary before writing any SQL
if the data to answer doesn't exist, it says so instead of making something up
every answer shows the query and its sources
works with Claude, Cursor and any agent through MCP
free and open source, 2,000 stars in a single day

running 5 Claude Code agents at once sounds great
until they start overwriting each other's code
Worktrunk gives every agent its own copy of your project
one command creates the copy and starts Claude on a task:
wt switch -x claude -c feature-a -- 'Add user authentication'
one command to list them, one to clean up
writes commit messages with AI too
