Cocoplus

CocoPlus is a plugin that adds a structured development workflow to Snowflake Coco, the Cortex Code agent for Snowflake. Its documentation calls it an agentic operating system for Coco: it turns the assistant into a development partner that follows a lifecycle, remembers project context, specializes by role and guards production data. It is built entirely from native Coco constructs, namely rules in AGENTS.md, subagents, skill files and lifecycle hooks, and it adds no external services, databases or background processes. It is written for data engineers working on Snowflake projects who want repeatable, auditable AI assisted work. The core lifecycle engine, CocoBrew, moves each piece of work through gated phases: spec, plan, build, test, review and ship, each producing a recorded artifact and git commit, with commands to rewind or fork. Other parts include CocoFlow pipelines, a persona system, a three layer memory, a Safety Gate that by default protects schemas named PROD, PRODUCTION or LIVE, token and warehouse cost tracking, and a CocoPilot layer that coordinates the rest. The documentation counts fifty five features and forty three design principles, and explains the reasoning behind each. Setup requires the Coco CLI connected to a Snowflake account and a git repository; installation is two plugin commands, followed by an init step that writes the project state directory. No pricing is published. The plugin installs directly from the Snowflake Labs repository on GitHub, and the site lists no paid tier. Users upgrading from an earlier release must run a provided migration skill rather than reinitializing the project.
