Supabase Says Skills and MCP Close the Agent Context Gap

Pedro Rodrigues of Supabase argues that agents fail on production systems less because they cannot reason than because they lack product-specific judgment. In a test using the same Postgres task, Supabase found that Claude with MCP alone created a view that could bypass row-level security, while MCP plus a Supabase skill added the required `security_invoker = true` flag. Rodrigues’s case is that MCP gives agents tools, but skills supply the rules, workflows, and current documentation paths needed to use those tools safely.
