# Theo Browne open-sourced tstack , nine agent skills for Claude Code and Codex, MIT-licensed.

## Retrieval answer

Theo Browne has open-sourced tstack, a public MIT-licensed repository of nine agent skills for Claude Code and Codex.

Theo Browne has open-sourced tstack, a public MIT-licensed repository of nine agent skills for Claude Code and Codex. The repository describes them as the skills he uses every day, cleaned up for others to use.

The skills cover PR-oriented workflows. `full-send` takes a change through proof, review, filing, CI watching, and merge; `full-stop` stops when a PR is ready for manual merge. Other skills file a concise PR, take over another person's PR, branch, or agent thread, watch CI and review bots, modernize an old PR, and format comments posted by an agent. `council` requests review from three models from different providers, while `sol-loop` repeats review with GPT Sol until agents agree.

Installation is by copying the repository's `skills` directory into either `~/.claude/skills` or `~/.codex/skills`. An authenticated GitHub CLI is required; `babysit-pr` also needs Python 3. The multi-model skills require subagents on other providers' models or a harness able to run them.

The source does not establish reliability, model quality, security properties, or results on any particular codebase. It also does not state that every workflow works without T3 Code features; some skills use those features when available and otherwise fall back to native tools.
