See what your coding agent sends. Mask what you can.
shim-cli is an open-source tool designed for developers working with AI coding assistants like Claude Code, Codex, and GitHub Copilot. It functions as a local proxy and hook, providing transparency into what data and code snippets are sent during AI interactions. One of its standout features is the ability to mask sensitive information, such as secrets and personal data, before they reach the AI model, enhancing privacy and security. Additionally, shim-cli offers a session monitoring feature with 'shim watch,' which displays what data was sent and the associated costs, giving developers better control and insight into their AI workflows. Its open-source nature, combined with the absence of telemetry and account requirements, makes it especially appealing for privacy-conscious developers who value transparency and local control.
Pros
- Open-source and privacy-focused
- Masks secrets and personal data effectively
- Provides session monitoring and cost tracking
- No account or telemetry required
- Supports multiple AI coding tools
Cons
- Limited to specific AI coding tools, may not support all platforms
- Requires local setup and configuration
- Potential learning curve for non-technical users
Best for
- • Monitoring and debugging AI coding sessions
- • Masking sensitive data in AI outputs
- • Cost analysis for AI tool usage
- • Enhancing privacy in AI-assisted coding workflows

Prevent product drift in AI-written code
Prelint is an innovative AI-powered code review tool designed to ensure code quality and consistency in teams leveraging AI-generated code. By automatically reviewing pull requests against architectural decision records (ADRs), documentation, and past decisions, Prelint helps prevent product drift and maintains alignment with project standards. Its unique capability to catch issues early—especially in environments where multiple AI reviewers are used—makes it an essential addition for modern development workflows. With the ability to identify approximately 40% of issues before merging, Prelint significantly reduces bugs and rework, leading to more reliable and maintainable codebases. Ideal for software engineering teams seeking to integrate AI into their CI/CD pipeline, it offers a proactive approach to code validation that complements traditional review processes.
Pros
- Automates comprehensive code review against ADRs, docs, and past decisions
- Prevents product drift early in the development lifecycle
- Reduces post-deployment bugs and rework
- Enhances team collaboration by enforcing standards
- Effective in environments with multiple AI reviewers
Cons
- May require initial setup to align with specific ADRs and documentation
- Dependent on the quality of input data and existing documentation
- Potential false positives in complex or rapidly evolving projects
