Security rules for AI coding agents

These files add security checks to Claude Code, Codex, GitHub Copilot in VS Code, and Pi. The checks run through hooks: small programs that run at set points, such as before an agent reads a file or runs a command. The agents share the same rules, with separate settings to connect each agent to the hooks.

This collection is published as a GitHub gist, a page for sharing files. It is a copy of files from a private repository. Some files require folders and settings that are absent here, so they need additional setup before use.

Cleanup legacy GitHub Actions workflow runs

Python utility to delete GitHub Actions runs for a repository, based on parameters. The GitHub UI currently allows removal of individual workflow runs, but this becomes tedious with a bulk of previous runs. Credit: https://gist.github.com/magnetikonline/2242eb18bf8890e9fc72b3c3ef41bd93

Usage
