Instead of thin API wrappers, we teach AI things like "Always index foreign key columns - Postgres won't do it for you" and "Use BIGINT GENERATED ALWAYS AS IDENTITY, not SERIAL."

Last week @anthropic.com announced Skills - turning generalist LLMs into domain experts through structured knowledge. Different implementation, same philosophy. (Our approach might show how to implement Skills entirely through MCP 🤔)

That's where our get_prompt_template MCP tool comes in. Ask "design a schema for IoT devices" in plain language. The AI automatically pulls in the right Postgres expertise. No slash commands, no template picking.

The fix isn't obvious. I hate the copy-paste prompting I see in the wild. MCP prompt templates bother me too - why should users need slash commands? Isn't the AI supposed to figure this out?

AI coding should make this better. Instead, it's making things worse. Every "AI-generated" schema has the same issues: wrong ID types, missing indexes, timezone nightmares. Infuriating.

I've spent 10 years at Timescale (now TigerData) watching devs make the same database mistakes: forgetting to index foreign keys, case-sensitive email lookups, arbitrary VARCHAR limits. The pain of botched migrations and downtime is real.

They just access the database and expect it to have the context.
But most databases can’t explain themselves. And that’s the core problem.
So we built a semantic catalog on top of Postgres. It added context inside the database. SQL accuracy improved by 27%.

China is over 2 million with "administrative detentions", as I specified in my post.

Of course we also have a smaller prison population than China www.prisonstudies.org/country/china If you count "administrative detentions"

US prison population (biggest estimate, way more than actual): 2 million
world population: 8 billion
tell me how that's 5%?
