unify CLAUDE.md

unify CLAUDE.md is an instructions file for coding agents from unifyai/unify. It costs 120 tokens per session, scanned C, original, MIT.

An instruction file that makes Claude Code, Codex, and Cursor use the same project guidance. It points these tools to the repository’s AGENTS.md file.

In plain words
What is it for?
Use it in projects where AGENTS.md contains the shared rules and Claude Code also needs a CLAUDE.md entry to load them.
Why use it?
It prevents different coding assistants from following different instructions when working in the same project.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 C, and why

unify CLAUDE.md scanned grade C with 1 finding 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 4d 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

<!-- Claude Code reads CLAUDE.md; Codex and Cursor read AGENTS.md natively. This file imports AGENTS.md so all three tools see the same instructions. Do not add rules here. AGENTS.md is generated - edit .agents/repo.md,

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.
