autoagent-action: Instructions file for Codex

AGENTS.md

autoagent-action AGENTS.md is an instructions file for Codex, OpenCode from erans/autoagent-action. It costs 1,807 tokens per session, scanned A, original, MIT.

Project instructions for AutoAgent, a GitHub Action that runs AI coding agents on repository pull requests. A pull request is a proposed code change that others review before it is merged.

In plain words
What is it for?
Use them when modifying AutoAgent’s action definition, documentation, result handling, tests, or pull-request analysis features.
Why use it?
They give a coding agent the project layout, important files, supported agents, and expected checks. This reduces the risk of making changes that conflict with the action’s workflow.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions Codex; mentions Gemini CLI.

This is erans/autoagent-action's own configuration. It tells Codex and OpenCode how to work on autoagent-action 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 autoagent-action 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

autoagent-action 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.

AutoAgent Project Structure

AutoAgent is a composable GitHub Action that integrates with multiple AI agents (Cursor CLI, Claude Code, Gemini CLI, Codex CLI, Amp Code, and OpenCode) to run automated code analysis and prompts on repositories as part of Pull Request workflows.

Project Overview

AutoAgent provides a standardized way to run AI-driven code analysis in GitHub Actions, offering predefined security checks, code reviews, and refactoring suggestions, plus support for custom prompts. It automatically installs the required AI agent and posts structured results back to the PR as comments.

Directory Structure

Root Files

File Purpose
action.yml GitHub Action definition with inputs, outputs, and execution steps
README.md User documentation with usage examples and configuration options
results.json Temporary file storing analysis results in JSON format
test.sh Comprehensive test script that validates the entire implementation

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.
