## Session Description
Everyone's building custom AI agents. We didn't. Instead, we built CAPTAIN — an MCP server that makes any off-the-shelf coding agent understand LinkedIn's entire engineering stack. The secret: a meta-tool architecture (discover → inspect → execute) and composable skills that encode tribal knowledge as executable workflows. 500+ skills later, it's used across all of LinkedIn engineering. I'll show you the architecture in 10 minutes and why context engineering beats model engineering every time.
