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

This is sumx21t-3310/FloatSoda's own configuration. It tells Codex and OpenCode how to work on FloatSoda 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 FloatSoda 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

FloatSoda 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This file provides guidance to coding agents — Codex, Claude Code (claude.ai/code), and others — when working with code in this repository.

This file is the single source of project instructions for every agent. Codex and other AGENTS.md-aware tools read it directly; Claude Code reads it through a one-line @AGENTS.md import in CLAUDE.md. Put project instructions here, never in CLAUDE.md — anything added there is invisible to every other agent.

Working Style

The repository owner develops hands-on and tracks the implementation themselves. By default, investigate and explain — do not modify code. When asked about a bug or behavior, report the root cause, the relevant files/lines, and (optionally) how a fix would look, but leave the actual implementation to the owner unless they explicitly ask you to make the change.

When you are asked to implement, how much you may take on depends on the kind of work — see the tiers in CONTRIBUTING.md (「コーディングエージェントに任せる範囲」): new APIs that Flutter does not have are implemented by a human; bug fixes start with investigation only; porting Flutter widgets (with Flutter's tests) may be delegated fully.

Output Language

Write all output to the repository owner in Japanese. This is a hard requirement, not a preference.

  • Code review — findings, severity reasoning, and suggested fixes are written in Japanese, even though the code and identifiers under review are English.
  • Investigation reports — root cause, affected files/lines, and how a fix would look.
  • Commit messages and PR titles/bodies.

Do not translate identifiers, type names, file paths, or code fences — those stay verbatim as they appear in the source.

Rationale: FloatSoda treats Japanese as the neutral (default) language — see LOCALIZATION.md. docs/, XML doc comments, and exception messages are all Japanese by design. Review output in Japanese keeps the entire surface consistent for the owner and for the LLMs that relay it to end users. If you feel English "should" be the default here, read LOCALIZATION.md before changing anything.

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.
