Extensions Detail

PI-Agy-ACP

Provides interactive or direct delegation to Google Antigravity via Agent Client Protocol (ACP). Supports selecting profile, model (gemini-3.8-flash, gemini-3.1-pro), reasoning effort (high, medium, low), and execution mode (auto_edit, default, yolo).

PI-Agy-Compat

Consolidates legacy Antigravity compatibility slash commands:

• /clear: Alias for /new to start a fresh session (e.g., /clear).
• /effort: Alias for /thinking to set or adjust the model's reasoning effort level (e.g., /effort high or /effort for interactive selection).
• /exit: Alias for /quit to exit Pi (e.g., /exit).
• /rename: Alias for /name to rename the current session (e.g., /rename My-Session or /rename without arguments to open an interactive prompt).

PI-Hello-World

A simple slash command extension demonstration that prints "Hello, World!".

PI-Laya-Obsidian

Obsidian & Laya Daemon integration for session note triaging, pre-commit compliance checks, and state note line limit enforcement. Includes commands /laya-status and /laya-triage, as well as tools obsidian_laya_triage and obsidian_precommit_check.
