vthink-agent-toolkit: Instructions file for Codex

AGENTS.md

vthink-agent-toolkit AGENTS.md is an instructions file for Codex, OpenCode from vthinkdeveloper/vthink-agent-toolkit. It costs 471 tokens per session, scanned A, original, MIT.

A toolkit of reusable instructions, AI roles, and workflows for coding assistants such as Claude Code, Cursor, Windsurf, and GitHub Copilot. It maps common development requests to the relevant skill or agent.

In plain words
What is it for?
Organizing skills and agents, following repository-specific workflows, and finding the right instructions for tasks such as committing code or extending the toolkit.
Why use it?
It helps an assistant choose the right procedure and project guidance for a task across different coding tools.

Instructions file for CodexOpenCode

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

This is vthinkdeveloper/vthink-agent-toolkit's own configuration. It tells Codex and OpenCode how to work on vthink-agent-toolkit itself, so it is not a mod to install elsewhere.

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

vthink-agent-toolkit 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 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.

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.

This file provides guidance to AI coding agents (Claude Code, Cursor, Windsurf, Gemini CLI, OpenCode, etc.) when working with code in this repository.

Repository Overview

vthink-agent-toolkit is a collection of production-grade skills, agents, and workflows for AI coding agents. Skills and agents are plain natural-language procedural instructions — they work in any agent runtime that can read markdown files.

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.
