When an AI coding assistant asks you to perform a manual task like checking its output, don't just comply. Instead, teach it the commands and tools (like Playwright or linters) to perform those checks itself. This creates more robust, self-correcting automation loops and increases the agent's autonomy.

A practical hack to improve AI agent reliability is to avoid built-in tool-calling functions. LLMs have more training data on writing code than on specific tool-use APIs. Prompting the agent to write and execute the code that calls a tool leverages its core strength and produces better outcomes.
AI code editors can be tasked with high-level goals like "fix lint errors." The agent will then independently run necessary commands, interpret the output, apply code changes, and re-run the commands to verify the fix, all without direct human intervention or step-by-step instructions.
As AI generates more code than humans can review, the validation bottleneck emerges. The solution is providing agents with dedicated, sandboxed environments to run tests and verify functionality before a human sees the code, shifting review from process to outcome.
Frame AI agent development like training an intern. Initially, they need clear instructions, access to tools, and your specific systems. They won't be perfect at first, but with iterative feedback and training ('progress over perfection'), they can evolve to handle complex tasks autonomously.
After an initial analysis, use a "stress-testing" prompt that forces the LLM to verify its own findings, check for contradictions, and correct its mistakes. This verification step is crucial for building confidence in the AI's output and creating bulletproof insights.
Use Playwright to give Claude Code control over a browser for testing. The AI can run tests, visually identify bugs, and then immediately access the codebase to fix the issue and re-validate. This creates a powerful, automated QA and debugging loop.
To maximize an AI agent's effectiveness, establish foundational software engineering practices like typed languages, linters, and tests. These tools provide the necessary context and feedback loops for the AI to identify, understand, and correct its own mistakes, making it more resilient.
Use 'stop hooks' in Claude Code to create an automated quality gate. After code generation, the hook runs checks like type checking or linting. If errors exist, the output is fed back to the AI with a prompt to fix them, creating a self-correcting workflow.
To get the best results from an AI agent, provide it with a mechanism to verify its own output. For coding, this means letting it run tests or see a rendered webpage. This feedback loop is crucial, like allowing a painter to see their canvas instead of working blindfolded.
An agent's effectiveness is limited by its ability to validate its own output. By building in rigorous, continuous validation—using linters, tests, and even visual QA via browser dev tools—the agent follows a 'measure twice, cut once' principle, leading to much higher quality results than agents that simply generate and iterate.
