Attentry: Local Checker Reviews Every Claude Code Edit

A new open-source tool called Attentry has launched to address a critical gap in AI-assisted development: verifying every code change an AI agent makes before it reaches your codebase. Posted to Hacker News on November 9, 2026, Attentry introduces a local verification layer specifically designed for Claude Code workflows, giving developers granular control over automated edits.

How Attentry Works

Attentry operates as a local checker that sits between Claude Code and your repository. Each time Claude Code generates an edit, Attentry intercepts the change and runs a verification process before allowing it to be applied. The tool runs entirely on the developer's machine, ensuring no code leaves the local environment during review.

The checker provides real-time feedback on proposed changes, flagging potential issues such as syntax errors, security vulnerabilities, or deviations from project coding standards. Developers can configure custom rules to match their team's requirements, from enforcing specific formatting conventions to blocking changes that touch sensitive files.

Release Date and Availability

Attentry was officially launched on November 9, 2026, via a Show HN post on Hacker News. The project is available now as an open-source repository on GitHub, allowing developers to inspect the code, contribute improvements, and adapt the tool to their specific workflows. The initial release targets developers already using Claude Code in production environments who need additional oversight.

Why Verification Matters

As AI coding assistants like Claude Code become more capable and autonomous, the need for verification tools has grown. While Claude Code excels at generating functional code quickly, developers have expressed concerns about blindly accepting machine-generated edits, especially in critical production systems. Attentry addresses this by providing a structured review process that maintains developer control.

• Prevents unintended changes from reaching production code
• Enables custom rule enforcement for team coding standards
• Provides audit trails for all AI-generated edits
• Runs locally without sending code to external services

Integration with Claude Code Workflows

Attentry integrates into existing Claude Code setups without requiring changes to the core AI assistant. Developers install the checker as a middleware layer that monitors the file system for Claude Code's proposed edits. The tool supports both manual approval workflows, where developers review each change individually, and automated validation, where predefined rules determine whether edits proceed.

The project's GitHub repository includes documentation for common use cases, from basic syntax checking to advanced pattern matching rules. Early adopters can contribute custom rule sets back to the community, building a shared library of verification patterns for different programming languages and frameworks.

What This Means

Attentry represents a broader trend in AI development tooling: the emergence of third-party verification layers that augment rather than replace AI assistants. By giving developers fine-grained control over automated edits, tools like Attentry make it safer to deploy AI coding assistants in high-stakes environments. As Claude Code and similar tools continue to evolve, verification infrastructure will likely become standard practice in professional development workflows.
