AGENTS.md

claude-code-starter AGENTS.md is an instructions file for Codex, OpenCode from artemiimillier/claude-code-starter. It costs 97 tokens per session, scanned A, original, MIT.

A project instruction file for Claude Code and Codex that points agents to the shared development process. It tells them how to find current plans and checkpoints without repeating the project's onboarding rules.

In plain words
What is it for?
Use it to define repository-level instructions for entering a project, continuing from a plan, preserving local agreements, and flagging conflicts.
Why use it?
It helps different coding agents follow the same project conventions and continue existing work instead of starting from the wrong context.

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

claude-code-starter 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 today.

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

Codex: вход в проект

Прочитай общий процесс перед работой. Это единый источник правил для Codex и Claude Code; не дублируй его здесь.

Начинай с текущей просьбы и доступного контекста, не с обязательного онбординга. Для продолжения найди действующий план и checkpoint. Локальные договорённости проекта сохраняй; конфликт требований явно обозначай владельцу.

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.
