fonline-tla: Instructions file for Codex

AGENTS.md

fonline-tla AGENTS.md is an instructions file for Codex, OpenCode from cvet/fonline-tla. It costs 4,491 tokens per session, scanned A, original, MIT.

Repository instructions for maintaining FOnline: The Life After, a multiplayer game built on a reusable game engine. They explain the split between engine code, gameplay scripts, native extensions, game content, configuration, and build files.

In plain words
What is it for?
Use them when changing AngelScript gameplay, dialogs, quests, AI, GUI behavior, native C++ extensions, game assets, configuration, or the CMake build setup.
Why use it?
They show an AI agent where changes belong and which parts should normally be treated as external. They also define the project’s build and verification workflow and preferred response language.

Instructions file for CodexOpenCode

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

This is cvet/fonline-tla's own configuration. It tells Codex and OpenCode how to work on fonline-tla 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 fonline-tla 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

fonline-tla 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 7d 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.

FOnline: The Life After - Agent Instructions

Project front door for AI maintainers working on FOnline: The Life After (TLA). Read this before changing anything. Keep this file as the single source for agent-facing repository practices; CLAUDE.md and .github/copilot-instructions.md intentionally point here.

What This Project Is

  • TLA is a multiplayer game built on top of the reusable fonline-engine submodule in Engine/.
  • The split is engine plus game:
    • Engine/ - upstream engine submodule. Treat as external unless the task explicitly requires an engine change.
    • Scripts/*.fos - AngelScript gameplay, dialogs, quests, AI, GUI behavior, and server/client hooks. The folder is flat except for Scripts/Json/.
    • SourceExt/*.cpp / SourceExt/*.h - project-local native C++ extensions registered from CMakeLists.txt.
    • Critters/, Items/, Maps/, Dialogs/, Gui/, Texts/, Resources/ - authored game content and assets.
    • TLA.fomain - master engine/game config and [SubConfig] profiles.
    • CMakeLists.txt / CMakePresets.json - build glue. Default local preset is auto into Build/Auto.
  • The user usually converses in Russian; answer the user in Russian unless asked otherwise.
  • Script comment language is Russian (owner decision 2026-06-20, reversing the prior English-only rule). In Scripts/*.fos: code comments and the per-file header block (see Docs/ScriptStyle.md) are written in Russian, and existing English comments are translated to Russian as files are touched. Exception: serialized/contract names stay English — ///@ Property/Enum/Setting/Event/RemoteCall, proto ids, text-pack keys, and identifiers (renaming them risks save/network/content migration). Agent-facing markdown (AGENTS.md, most of Docs/) and native C++ (SourceExt/) remain English; player-facing text follows the existing localized pack structure.
  • Text packs are baked for russ engl; Client.Language = engl in the default config. When editing player-facing text, preserve the existing pack structure and update both language surfaces when the nearby content expects that.

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.
