To start with, our parser supports Gemini CLI, Codex, Claude Code, Pi, and GitHub Copilot CLI. If you use a different tool, you're encouraged to open a PR or Issue on Forem to add a new parser yourself or ask us to do so. As an example, you can check out how our Gemini CLI parser works in our GitHub commit: https://github.com/forem/forem/commit/8f92c64a775ed3a0993e5edc0637112a95d1dae2#diff-d98a98bdd6e0d9154df5559b53644185d4ab13160e85c0fdaae3013ff985e27b
