Some details of my current agent coding environment:

1. WebFetch: Allow all domains—permission fatigue costs more than the risk.

2. Project switcher: Helper script to launch Claude or Codex in the right folder.

3. Question mode: Prefix messages with ? to prevent Claude from editing files when you just want to ask a question.

4. Google Docs: Gdoc CLI is the best way to edit Google Docs.

5. “Try” for experiments: Use Tobi Lutke’s Try tool for managing quick experiments.

6. My CLAUDE.md: A recent version of my global CLAUDE.md.

7. Keep conversation history: Tell Claude Code to store past conversations indefinitely. By default it deletes after 30 days.

8. Date errors: LLMs sometimes offset calendar dates by one day. Fix it with a Python script.

9. Share skills between agents: Store skills in ~/.agents/skills/ and symlink to make them work in Claude Code, Codex and Gemini.

10. Browser use: Enable Claude to test its work in Chrome.

11. Quick Look markdown files: Use QLMarkdown to preview files with rendered markdown in Mac OS Finder.
