Version control instructions for Jonathan's workflow using jujutsu (jj) exclusively. Use this skill for ANY version control task — commits, branches, history, rebasing, pushing, merging, reviewing changes, or navigating a repo. Jonathan does NOT use git directly; all VCS operations must use jj commands. Trigger this skill whenever the user asks about commits, branches, history, diffs, pushing code, reviewing changes, undoing changes, or any other version control operation.

Query and inspect PostgreSQL schemas, tables, types, and data in the local development database. Use this skill whenever the user asks about the database schema, wants to inspect a table or type, needs to run a query, or asks anything involving PostgreSQL, psql, or the dev database. Trigger on phrases like "what columns does X have", "check the schema", "look at the type", "query the db", "what does the X table look like", or any time understanding the data model would help answer the question.
