Codex uses @ponytail, @ponytail-review, and @ponytail-help; Claude Code
and OpenCode use the slash-command forms above (OpenCode ships all six as
slash commands).
Deactivate
Say "stop ponytail" or "normal mode". Resume anytime with /ponytail.
/ponytail off also works.
Configure Default Mode
Default mode = full, auto-active every session. Change it:
Environment variable (highest priority):
export PONYTAIL_DEFAULT_MODE=ultra
Config file (~/.config/ponytail/config.json, Windows: %APPDATA%\ponytail\config.json):
{ "defaultMode": "lite" }
Set "off" to disable auto-activation on session start, activate manually
with /ponytail when wanted.
Resolution: env var > config file > full.
Update
Enable auto-update once: open /plugin, go to Marketplaces, pick ponytail, Enable auto-update. Claude Code then pulls new versions at startup (run /reload-plugins when it prompts). Manual refresh: /plugin marketplace update ponytail then /reload-plugins.
If /plugin is not recognized, your Claude Code is out of date. Update it (npm install -g @anthropic-ai/claude-code@latest, or brew upgrade claude-code) and restart. Other hosts use their own update flow.
