evc: Instructions file for Codex

AGENTS.md

evc AGENTS.md is an instructions file for Codex, OpenCode from SaigonXIII/evc. It costs 250 tokens per session, scanned A, original, MIT.

A cross-platform instruction file for coding-agent tools such as Claude Code, Cursor, Codex CLI, and Gemini CLI. It explains which configuration files each tool reads and sets shared working rules.

In plain words
What is it for?
Use it to configure agent instructions, point agents to shared project guidance, require content staging before publishing, and prevent automatic external posting without approval.
Why use it?
It keeps agent behavior consistent across different coding tools and makes project instructions easier to apply in each environment.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is SaigonXIII/evc's own configuration. It tells Codex and OpenCode how to work on evc 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 evc 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 A, and why

evc AGENTS.md scanned grade A with 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

EVC — Cross-Platform Agent Config

This file provides instructions for non-Claude Code agent harnesses (Cursor, Codex CLI, Gemini CLI).

For Claude Code

Claude Code reads CLAUDE.md and .claude/commands/*.md automatically. No additional configuration needed.

For Cursor

Copy .claude/commands/*.md to .cursor/rules/ and rename as needed. Cursor uses rules files instead of commands.

For Codex CLI

Codex reads AGENTS.md (this file) as its primary instruction source. The commands in .claude/commands/ can be referenced as prompts.

For Gemini CLI

Gemini reads GEMINI.md if present. Copy CLAUDE.md to GEMINI.md for equivalent behavior.


Universal Instructions (for any harness)

  1. Read SOUL.md for operating principles
  2. Load brand/canon-rules.json before writing any content
  3. Check content-engine/memory/lessons.md for accumulated knowledge
  4. Stage all content in staging/ before external publish
  5. Never auto-post to external channels without explicit approval
Changes

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.
