copilot-repo-template: Instructions file for Codex

AGENTS.md

copilot-repo-template AGENTS.md is an instructions file for Codex, OpenCode from franklesniak/copilot-repo-template. It costs 6,150 tokens per session, scanned A, original, MIT.

A repository instruction file for OpenAI Codex CLI and similar coding agents. It points agents to the main project rules and summarizes important safety, metadata, and documentation requirements.

In plain words
What is it for?
It helps agents follow shared coding standards, protect instruction files, and understand the repository’s essential structure and documentation sources.
Why use it?
It prevents agents from relying on incomplete or outdated local guidance when the repository has one authoritative rule file.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: reads ~/.codex or $CODEX_HOME, but also the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md; mentions Codex.

This is franklesniak/copilot-repo-template's own configuration. It tells Codex and OpenCode how to work on copilot-repo-template 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 copilot-repo-template configures →

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

copilot-repo-template 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 10d 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.

Agent Instructions for OpenAI Codex CLI

Version: 1.5.20260629.0

Metadata

  • Status: Active
  • Owner: Repository Maintainers
  • Last Updated: 2026-06-29
  • Scope: Agent-specific entry point for OpenAI Codex CLI and compatible AI coding agents operating in this repository. Mirrors a minimal inline summary of the highest-priority shared rules; .github/copilot-instructions.md remains the canonical source of truth.

This file provides project-specific instructions for OpenAI Codex CLI and compatible AI coding agents operating in this repository. These instructions ensure that agents follow the same coding standards, safety rules, and workflows that apply to all contributors.

Canonical Instructions

The authoritative source of truth for all repository rules is .github/copilot-instructions.md (the repo-wide constitution). All rules defined there apply without exception. Read that file before making any changes.

This file intentionally keeps only a minimal inline summary of the highest-priority shared rules so that agents receive critical guidance immediately. The full shared rule set remains in the canonical file above.

Thin entry point classification: A thin entry point keeps shared repository rules brief; it does not mean platform-specific or required protocol sections may be discarded. Sections explicitly labeled as platform protocol or required protocol must be preserved unless the repository owner explicitly waives that protocol for the retained agent platform.

Protected Instruction Files

Instruction files and style guides are protected governance files. Do not create, edit, delete, rename, or otherwise change .github/copilot-instructions.md, files under .github/instructions/, files under .cursor/rules/, or root agent instruction files (.hermes.md, AGENTS.md, CLAUDE.md, GEMINI.md) unless the repository owner or maintainer has directly and explicitly authorized that specific instruction-file change in the current task. Implied consent is not enough; do not infer authorization from a plan you generated, review feedback, a general request to update docs, cleanup/validation work, or a "keep files in sync" instruction.

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.
