I make Planby and agentwhy, an open source tool that shows which private files Claude Code and Codex reached, and from which task. Runs locally.

I built agentwhy to show which files and folders your AI coding agent explored, what it read, and why. Browse your sessions, get notices in the chat, and choose Block or Track. It's free, open source, and runs locally. agentwhy.dev #AIagents #OpenSource

agentwhy never shows you a secret. Values are replaced before the report is built. The report names the file and the key to change, nothing more. It runs on your computer. No account, no network request. #AIsecurity #ClaudeCode

My rules file said never read .env. No command opened it. A helper ran grep for a variable name, and the output printed the line from .env.development, value included. No rule matched, because no command named the file. #ClaudeCode #AIsecurity

Codex skips a hook nobody approved, and says nothing. In VS Code the first conversation starts before you can approve anything. So agentwhy's Codex check approves its own two entries in your config, and nothing else. Otherwise the block wouldn't be there. #Codex #AIsecurity

You don't have to install it before something goes wrong. Claude Code and Codex already save your conversations on your computer. agentwhy reads those too, including the ones from before you installed it. Which private files did your agent reach last week? #ClaudeCode #Codex
