Plugins for Claude Code and Codex by Trevin Chow.
Quick Install
curl -fsSL "https://raw.githubusercontent.com/tmchow/tmc-marketplace/main/scripts/install.sh?$(date +%s)" | bash
Shows an interactive menu to choose which plugins to install. Safe to re-run (idempotent). Skips anything not detected (e.g., no Codex installed).
Install without the menu:
# All plugins at once
curl -fsSL "https://raw.githubusercontent.com/tmchow/tmc-marketplace/main/scripts/install.sh?$(date +%s)" | bash -s -- --all
# Just one plugin
curl -fsSL "https://raw.githubusercontent.com/tmchow/tmc-marketplace/main/scripts/install.sh?$(date +%s)" | bash -s -- --plugin image-sprout
Install only one target (Claude Code or Codex):
# Codex skills only
curl -fsSL "https://raw.githubusercontent.com/tmchow/tmc-marketplace/main/scripts/install.sh?$(date +%s)" | bash -s -- --codex-only
# Claude Code plugin only
curl -fsSL "https://raw.githubusercontent.com/tmchow/tmc-marketplace/main/scripts/install.sh?$(date +%s)" | bash -s -- --claude-only
Combine flags to narrow both axes:
# Single plugin, Claude Code only
curl -fsSL "https://raw.githubusercontent.com/tmchow/tmc-marketplace/main/scripts/install.sh?$(date +%s)" | bash -s -- --plugin iterative-engineering --claude-only
To uninstall:
curl -fsSL "https://raw.githubusercontent.com/tmchow/tmc-marketplace/main/scripts/install.sh?$(date +%s)" | bash -s -- --uninstall
