According to CoinMeta, Wu said that Coinbase revealed its internal AI engineering assistant Ceecil. This system is capable of memorizing team historical discussions, recent context, and key decisions within Slack, and can invoke real-time query tools when necessary to assist the engineering team in handling cross-timezone handovers and troubleshooting. Ceecil adopts a layered routing mechanism; simple requests are directly handled by API or the knowledge base, while more complex tasks are handed over to the complete AI. Its architecture connects memory, the knowledge base, and Slack through MCP, and it also sets limitations such as privacy scope, kill, switch, cost caps, and manual reviews.
