How to use vibe coding with agentic AI for coding

TL;DR

Vibe coding uses a language model to generate code while the developer iterates inside an IDE using tools to run, test, and refine. It emphasizes a flow from desired output to actionable steps, with spec driven design, automated testing, and built in review and rollback capabilities to keep development fast and reliable.

Today we're breaking down vibe coding. What vibe the next level with techniques like spec-driven is safe, testable, and shippable. Now let's get already as part of a IDE like VS Code or Intelligj their code, right? And for example, let's say we We're working on some code in this space and assisted coding uh extension or it's part of to a coding mod... Read More

Key Insights

• Vibe coding is a workflow for building applications using agentic AI that goes beyond simple code generation.
• The process centers on a loop of producing a desired output and iterating with tools inside the IDE.
• It is well suited for tasks like scaffolding apps, scripting, and API integration within a Git controlled workflow.
• Vibe coding relies on a language model to think about code and then propose iterations and actions to take.
• The approach includes architecture design, testing first, and spec driven development to guide implementation.
• Automated testing and continuous integration practices are considered important for reliable outputs.
• Security concerns such as handling API keys and secrets are acknowledged as risks in the vibe coding flow.
• Tooling like Git is recommended to maintain structure and provide revert capabilities as features are added.

Questions & Answers

Q: How to start vibe coding with agentic AI in an IDE

To start vibe coding with agentic AI in an IDE you set up the coding agent within your editor such as a VS Code or IntelliJ integration. Begin with a clear desired outcome for the feature or app, then let the agent propose code and tests. You review and approve iterations, run tests, and refine the implementation in cycles. This creates a loop of thought, action, and verification that speeds up development while preserving control over changes.

Q: What is the role of spec driven development in vibe coding

Spec driven development in vibe coding uses a predefined specification to guide the generated code and its tests. The agent focuses on meeting the spec before moving to the next increment, which helps reduce ambiguity and aligns the output with the intended architecture. This practice improves predictability and makes failures easier to diagnose.

Q: How does vibe coding handle testing and reviews

Vibe coding incorporates automated testing and reviews as part of the iteration loop. After each code suggestion, tests are run to validate behavior, and the output can be linted and type checked. Reviews are done by both the developer and the coding agent, providing a structured quality gate before code is pushed.

Q: What are the architectural benefits of vibe coding

Architecturally, vibe coding encourages thinking in terms of modular components and clear interfaces. By outlining multiple outcomes and using tools for integration, it supports scalable design and reuse. It also helps map dependencies and service boundaries early, reducing later refactoring and enabling smoother evolution of the codebase.

Q: What risks are associated with vibe coding

Risks in vibe coding include hallucinations from the model, overlooked security concerns like handling API keys, and skipping tests or reviews. The approach emphasizes monitoring and governance, including secret management and CI practices, to mitigate these issues and ensure that generated code remains trustworthy.

Q: How does vibe coding integrate with Git and version control

Vibe coding integrates with Git to ensure features are added in a structured way and that changes can be reverted if necessary. The workflow typically involves committing incremental improvements after passing tests, enabling teams to track progress, revert problematic updates, and maintain a stable baseline while iterating toward the final product.

Q: Can vibe coding be used for API key management and security

The video warns that vibe coding can be sensitive to handling API keys and secrets. To use it securely, developers should implement best practices such as not embedding keys in generated code, using secret stores, and integrating with CI pipelines that scan for leaks. Security-conscious workflows help reduce risk during automated development.

Q: What is meant by running code on the fly in vibe coding

Running code on the fly in vibe coding refers to executing generated or modified code directly within the development environment to get quick feedback. This rapid loop of coding, running, and observing results accelerates iteration, but requires safeguards such as tests, linting, and controlled execution to avoid unstable changes.

Summary & Key Takeaways

• Vibe coding combines agentic AI with prompt engineering to guide code generation inside an IDE, enabling iterative development and quick feedback loops.

• The approach emphasizes architecture, test driven and spec driven development, and the integration of automated testing and reviews to improve code quality.

• Security, secrets management, and risk awareness are discussed as important considerations when using vibe coding to push code changes.
