agex gamify --agent <backend> / agex gamify --uninstall --agent <backend>

What it does

Writes backend-native hook fragments (each tagged with a stable agex:* ID) that call agex hook write <event> on PostToolUse, UserPromptSubmit, and Stop events. Agent-authored skills (e.g., levelup) read the accumulated data via agex hook read.

Why it’s safe

• Idempotent: re-running is a no-op.
• Reversible: --uninstall removes exactly the agex:* fragments; user-authored hooks are untouched.
• Calling agex gamify explicitly is the confirmation — no separate prompt.

Unsupported backends

If your backend doesn’t support hooks, you get a markdown notice + issue link instead.

From your shell tool

agex gamify --agent claude-code
# ... use your runtime for a while ...
agex hook read --agent claude-code
# ... later, to undo:
agex gamify --uninstall --agent claude-code
