fusion-tea: Instructions file for Codex

AGENTS.md

fusion-tea AGENTS.md is an instructions file for Codex, OpenCode from 1cFE/fusion-tea. It costs 206 tokens per session, scanned A, original, MIT.

A project instruction file that tells a coding assistant which documents to read and which modeling rules and process to follow.

In plain words
What is it for?
It helps guide modeling tasks in the fusion-tea project by pointing to its context, tools, guide, and process.
Why use it?
It gives the assistant project-specific context instead of leaving it to guess how the work should be done.

Instructions file for CodexOpenCode

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

This is 1cFE/fusion-tea's own configuration. It tells Codex and OpenCode how to work on fusion-tea 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 fusion-tea 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

fusion-tea 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 24d 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.

What it actually says

Modeling project

Read .agentic-mbse/codex.md for assistant-specific tools and modeling_project/OVERVIEW.md for project context. Follow modeling_project/MODELING_GUIDE.md and modeling_project/MODELING_PROCESS.md when modeling.

Read CLAUDE.md for the existing project instructions, including the coding/modeling ownership boundary, source quarantine, and Python environment rules. Read .project/CURRENT_WORK.md before non-trivial work. Local study skills in .agents/skills/ point to the canonical .claude/skills/ bundles; apply the Codex adapter to their tool names.

For this test worktree, read .project/codex-test-setup.md before running Python or modeling commands.

Worktree setup, moved from .agentic-mbse/codex.md:11

Use .codex-test/run for toolkit/Python commands as documented in .project/codex-test-setup.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.
