Tech stack
  • Claude Code
    Anthropic's agentic coding tool: Unleash Claude's raw power directly in your terminal or IDE to turn complex, hours-long workflows into a single command.
    Claude Code is Anthropic’s powerful agentic coding assistant, designed for high-velocity development. It operates natively within your terminal, IDE (VS Code, JetBrains), or via a web interface, allowing you to delegate complex tasks like feature building, bug fixing, and codebase navigation. The agent plans, edits files, executes commands, and creates commits, maintaining awareness of your entire project structure. Internally, Anthropic engineers using Claude Code reported a 67% increase in productivity, demonstrating its capacity to deliver significant gains for Pro and Max plan users.
  • Claude Agent SDK
    The Claude Agent SDK (Python, TypeScript) transforms Claude into an autonomous, production-ready agent by granting it controlled access to a computer: file operations, Bash execution, and external tool integration via the Model Context Protocol (MCP).
    This SDK provides the core agent harness that powers Claude Code, enabling developers to build sophisticated, general-purpose agents. It offers official TypeScript and Python libraries for seamless integration. Agents gain powerful, safe capabilities: reading and writing files, executing sandboxed Bash commands, and leveraging a rich tool ecosystem. The framework includes essential production features (e.g., automatic context management, granular permission modes like `acceptEdits`, and built-in cost tracking). Use the open Model Context Protocol (MCP) to connect custom tools, databases, and APIs, extending Claude’s utility far beyond simple chat to complex, multi-step workflows.
  • Codex
    Codex is OpenAI's autonomous AI software engineering agent: it executes full development tasks in a sandboxed cloud environment.
    Codex is the advanced, cloud-based software engineering agent from OpenAI, built on a specialized model like `codex-1` (a fine-tuned version of `o3`). It operates on an asynchronous delegation model, allowing developers to assign complete tasks—not just receive suggestions—via the ChatGPT interface. The agent works independently in a secure, isolated cloud container provisioned with the user's GitHub repository and environment. It reads code, writes new features, fixes bugs, runs tests, and drafts Pull Requests (PRs) for review, significantly accelerating the development lifecycle. Access is provided through ChatGPT Plus, Pro, and Enterprise plans.
  • Codex SDK
    The Codex SDK (Software Development Kit) provides a robust TypeScript library for embedding the full power of the Codex agent into server-side applications (Node
    The Codex SDK (Software Development Kit) provides a robust TypeScript library for embedding the full power of the Codex agent into server-side applications (Node.js v18+). This is your direct control channel: use it to programmatically manage complex engineering tasks, initiate multi-step code generation threads, and build custom AI-powered agents. Key use cases include automating CI/CD pipelines, triggering code fixes via GitHub Actions, and integrating advanced code review into internal tools. The SDK is designed for deep, custom integration, offering unmatched flexibility over the out-of-the-box Codex CLI or IDE extensions.
  • Python
    Python: The high-level, general-purpose language built for readability, powering everything from web backends to advanced machine learning models.
    Python is the high-level, general-purpose language prioritizing clear, readable syntax (via significant indentation), ensuring rapid development for any team . Its ecosystem is massive: use it for robust web development with frameworks like Django and Flask, or leverage its power in data science with libraries such as Pandas and NumPy . The Python Package Index (PyPI) provides thousands of community-contributed modules, offering immediate solutions for tasks from network programming to GUI creation . The language is actively maintained by the Python Software Foundation (PSF), with the stable release currently at Python 3.14.0 (as of November 2025) .
