Snowflake Extends Cortex Code CLI to dbt and Apache Airflow

Key Facts

What: Snowflake has extended its Cortex Code CLI, a terminal-based AI coding agent, with native support for dbt and Apache Airflow
Capabilities: The tool can analyze run_results.json, identify slow models, suggest fixes, flag unused models, and create or optimize full dbt pipelines from a single prompt
Use Cases: Supports dbt model development, debugging, optimization, Airflow DAG creation, troubleshooting, and performance tuning
Availability: Cortex Code CLI is available now for data practitioners working in Snowflake environments
Approach: Delivers secure, context-aware assistance directly in the terminal or IDE

Lead paragraph

Snowflake announced extended support for its Cortex Code CLI to dbt and Apache Airflow, enabling data engineers to streamline complex data transformation and orchestration workflows using natural language prompts. The terminal-based AI coding agent can now analyze dbt project artifacts such as run_results.json, automatically identify performance bottlenecks, suggest optimizations, flag unused models, and even generate or debug entire pipelines from a single prompt. The update aims to reduce the time data practitioners spend on repetitive engineering tasks from hours to minutes while maintaining security and context awareness within Snowflake's data platform.

Cortex Code CLI: From Analysis to Action

Cortex Code CLI functions as an AI-powered assistant that operates directly in developers' terminals or integrated development environments. According to product demonstrations, users can prompt the tool to review their dbt project's run results, surface the slowest-running models, and receive concrete recommendations for improvement. The system goes beyond simple identification by proposing specific code changes and architectural adjustments to address identified bottlenecks.

The tool's dbt support includes the ability to create and validate complete dbt pipelines from a single natural language instruction. It can scan source tables, generate appropriate models, and produce the necessary configuration files while remaining grounded in the user's existing project structure. This capability is particularly valuable for teams managing large, complex dbt deployments where manual optimization has traditionally been time-consuming.

Integration with Apache Airflow

In addition to dbt, the expanded Cortex Code CLI offers targeted support for Apache Airflow users. The AI agent can assist with DAG creation, troubleshoot existing workflows, and tune performance of data pipelines. This dual support addresses two of the most widely used technologies in modern data engineering stacks, particularly those built on or around the Snowflake platform.

Industry observers note that the integration allows data teams to maintain their preferred tools while gaining AI assistance for the more tedious aspects of pipeline maintenance. The CLI reportedly maintains awareness of the broader project context, helping it provide suggestions that align with existing coding standards and organizational governance requirements.

Technical Capabilities and Workflow

The core workflow enabled by Cortex Code CLI transforms traditional debugging and optimization processes. Instead of manually reviewing logs and performance metrics, engineers can simply instruct the tool to "analyze my dbt project for performance issues" or "optimize slow models in this directory."

According to coverage by InfoWorld, the extension delivers "secure, context-aware" assistance that respects the security boundaries of the Snowflake environment. This is critical for enterprises handling sensitive data who require AI tools that do not expose information outside approved perimeters.

The tool's ability to process run_results.json files — a standard output from dbt test and run commands — allows it to leverage existing metadata rather than requiring additional instrumentation. It can identify not only slow models but also unused or redundant ones that may be inflating maintenance costs and complicating project governance.

Industry Context and Competitive Landscape

Snowflake's move reflects the growing trend of embedding AI assistance directly into data engineering workflows. As organizations scale their data platforms, the complexity of maintaining transformation logic and orchestration grows exponentially. Tools like Cortex Code CLI aim to make these systems more manageable without requiring teams to learn entirely new platforms or frameworks.

The announcement positions Snowflake as a provider of both the data platform and the AI-powered development tools that operate on top of it. This vertical integration potentially offers advantages in terms of performance, security, and context awareness compared to third-party AI coding assistants that lack native understanding of Snowflake's architecture and security model.

Impact on Data Teams

For data engineers and analytics engineers, the extended Cortex Code CLI could significantly reduce the time spent on maintenance and optimization tasks. Rather than spending hours profiling slow models or debugging failed DAG runs, practitioners can leverage the AI agent to accelerate these processes.

The tool's focus on practical outcomes — moving "from bottlenecks to action in minutes" — addresses a common pain point in data organizations where technical debt in transformation layers often accumulates faster than teams can address it. By making optimization more accessible, Snowflake hopes to help teams maintain cleaner, more performant data pipelines.

Development teams working in regulated industries may particularly benefit from the secure, context-aware nature of the CLI, as it operates within the Snowflake security boundary rather than sending code to external large language models.

What's Next

While specific future roadmap details were not disclosed in the announcement, the expansion to dbt and Airflow suggests Snowflake may continue broadening Cortex Code CLI's support to additional data tools and frameworks commonly used alongside its platform.

Data teams interested in the tool can access it through Snowflake's offerings, with demonstrations available showing end-to-end workflows from prompt to production-ready dbt pipelines. The company has published resources including video walkthroughs showing the tool creating and validating full dbt projects from natural language instructions.

As AI assistance becomes more prevalent in data engineering, tools like Cortex Code CLI represent an important step toward making advanced data platform capabilities accessible to a broader range of practitioners while improving productivity for experienced engineers.

Cortex Code CLI can optimize your dbt project in one prompt.
