 /**
- * Context Warn + Voice Extension
+ * Context Warning Extension
  *
- * 1. Emits a sound alert when the context window reaches 100k tokens.
+ * Emits a generated sound alert when the context window reaches or exceeds
- * 2. Registers a /speak command so the agent can vocalize conclusions.
+ * 100 000 tokens. Also shows a UI notification.
  *
  * Usage:
- *   pi install git:git.enne2.net/enne2/context-warn@main
+ *   pi -e ./context-warn-extension/index.ts
  *
- * Commands:
+ * Or place in ~/.pi/agent/extensions/context-warn/ for auto-discovery.
- *   /context-warn-status — Show current context usage
- *   /context-warn-alert  — Manually test the alert sound
- *   /speak <text>        — Speak the text aloud (for the agent to use)
