About Agnix

Agnix is a linter tool that checks AI agent configuration files for errors and problems. It validates files like SKILL.md, CLAUDE.md, hooks, MCP (Model Context Protocol) settings, and related configuration to help catch mistakes before they cause issues.

Who it’s for

Developers building AI agent systems who want to verify their configuration files are correctly formatted and valid. Teams using MCP servers or Claude integration who need automated checking of setup files.

Alternatives

  • ESLint (for JavaScript/TypeScript config validation)
  • JSON Schema validators (generic file structure checking)
  • yamllint (for YAML configuration files)
  • Manual code review (human inspection of agent configurations)

Setup

Check these steps against the project’s own instructions before running anything.

Install via npm:

npm install -g agnix

Or run directly:

npx agnix

Follow the project's README for configuration options and how to lint your agent files.

Why this grade

Risks to watch for

  • Configuration file access: Can read and analyze your agent setup files, which may contain sensitive settings, API keys, or tool definitions if improperly stored in plaintext
  • Malicious config interpretation: A compromised version could hide malicious hooks or MCP server references in configuration that the linter misses or endorses
  • Data in error messages: If linting fails, error output might expose parts of your configuration files in logs or console output
  • Supply chain risk: As an npm package, it depends on third-party dependencies that could be compromised, affecting any systems using the linter
  • Local file system access: Runs locally and can access configuration files in your project directory during validation

How to lower the risk

Least-privilege permissions

  • Run linting in isolated development environments, not production systems
  • Don't store API keys or secrets directly in config files it will scan

Network isolation

  • Use agnix only on local machines during development
  • Don't run it on shared or untrusted networks without firewalls

Monitoring

  • Review npm package changelogs before updating to new versions
  • Check that linting output doesn't log sensitive configuration data

Red flags to watch for

  • Unexpected network activity when running the linter
  • New dependencies added in recent package versions
  • Linter endorsing obviously malformed or suspicious configurations
