pi-codex-profile

Codex performance profile for pi coding agent.

No command needed: once the extension is loaded (/reload), it works automatically when your active model is Codex.

What it improves

1) Codex operating profile (auto-injected)

When a Codex model is active, the extension appends a comprehensive Codex profile to the system prompt.

It includes high-impact coding guidance adapted from the Codex Prompting Guide and updated for newer Codex behavior:

• tool-first behavior (prefer dedicated tools, rg for search)
• autonomy and persistence (ship end-to-end, avoid plan-only, phase medium/large tasks)
• cleaner editing workflow (batch edits, preserve user changes)
• safer behavior (avoid destructive actions unless explicitly requested)
• evidence-based verification and concise final responses

UI status shows when active: Codex profile.

2) apply_patch tool

Adds a Codex-style apply_patch tool to handle patches like:

• *** Add File:
• *** Update File: (with optional *** Move to:)
• *** Delete File:

The parser/patching flow is aligned with the OpenAI cookbook apply_patch format and behavior.

Install

pi install npm:pi-codex-profile

Example patch

*** Begin Patch
*** Update File: src/example.ts
@@
-old line
+new line
*** End Patch

Notes

• Works only when the current model is recognized as Codex.
• Paths are restricted to the current working directory (no absolute paths).
• The injected profile remains coding-focused (debugging, refactors, migrations, tests, CI).
