Opencode style permissions and preview

A Pi package for agentic coding workflows, with a focus on stronger tool permissions, better edit/write review, and practical extensions for everyday use.

Install in Pi

Global install from git

pi install git:github.com/JayGhiya/pi-opencode-permissions-and-preview

Included extension highlight: permission

The permission extension adds a configurable permission layer on top of Pi tool calls.

Brief functionality

• allow / deny / ask rules for tool calls
• session-only and persisted approvals
• AST-aware bash permission matching
• custom preview and review UI for edit and write
• pierre diff preview for overwrites and edits
• full-content preview for brand-new writes
• reject with feedback flow

For edit and write, the permission prompt includes a compact preview and a larger review mode with Ctrl+F, plus scrolling with PgUp / PgDn.
