A pi extension for plan mode — read-only exploration and analysis.

• /plan command — Toggle plan mode on and off
• Configurable shortcut — Optional keyboard shortcut via /extension-settings
• Read-only tools — Only safe, non-modifying tools are available while in plan mode
• Session persistence — System reminders are kept in session history, so what the LLM sees is exactly what you see
• Status indicator — Shows ⏸ plan in the status bar when active
• Powerbar support — Emits a ⏸ plan segment to pi-powerbar when plan mode is active

pi install npm:@juanibiapina/pi-plan

Use /plan to toggle plan mode. When enabled:

• Only read-only tools are available (read, bash, grep, find, ls, questionnaire)
• The agent is instructed to only observe, analyze, and plan — no modifications
• A ⏸ plan indicator appears in the status bar

Use /plan again to return to normal mode with full tool access.

No shortcut is bound by default. To configure one, use /extension-settings and set the shortcut setting under plan (e.g. tab, ctrl+p).

Note: The /extension-settings command is provided by the @juanibiapina/pi-extension-settings package, which must be installed separately:

pi install npm:@juanibiapina/pi-extension-settings

Start pi directly in plan mode:

pi --plan

Plan mode works by injecting system reminder messages into the session when the mode changes. These messages instruct the LLM to operate in read-only mode (or restore full access when exiting). The messages are kept in the session history, so what is sent to the LLM is always exactly what you see in the session — no hidden prompt manipulation. When resuming a session that was in plan mode, the mode is automatically restored from these messages.
