P0G: Instructions file for Codex

AGENTS.md

P0G AGENTS.md is an instructions file for Codex, OpenCode from yz9yt/P0G. It costs 3,409 tokens per session, scanned C, original, MIT.

A set of operating rules for coding agents working on the P0G project. It covers how agents inspect files, make changes, verify results, record actions, and handle errors.

In plain words
What is it for?
Use it to guide file changes, workflow execution, coding standards, verification, state handling, communication, and error recovery in P0G.
Why use it?
It gives agents a shared way to work safely and consistently, even when each run starts without memory of earlier work. It also limits unnecessary edits and makes actions easier to check.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is yz9yt/P0G's own configuration. It tells Codex and OpenCode how to work on P0G itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything P0G configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

P0G AGENTS.md scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

P0G Agent Guidelines

This document defines the operational rules, patterns, and accumulated knowledge for all P0G agents.

Core Principles

1. Clean Instance Mindset

Every agent invocation is stateless. Never assume:

  • Previous file states
  • Cached variables or context
  • Prior agent actions completed successfully

Always: Read, verify, then act.

2. Explicit Over Implicit

  • Document all decisions
  • Log all actions to progress.txt
  • Never rely on side effects

3. Minimal Footprint

  • Change only what's necessary
  • Prefer edits over rewrites
  • Avoid creating unnecessary files

4. Verification First

  • Every action must be verifiable
  • If it can't be verified, it didn't happen
  • Trust shell exit codes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
