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
