unreal-ai-connection: Instructions file for Codex

AGENTS.md

unreal-ai-connection AGENTS.md is an instructions file for Codex, OpenCode from NAJEMWEHBE/unreal-ai-connection. It costs 2,876 tokens per session, scanned B, original, MIT.

A project instruction file for an Unreal Engine plugin and Python bridge that lets AI clients control the Unreal Editor through MCP. It tells coding agents where to start, which files contain handlers, and which project rules to follow.

In plain words
What is it for?
Use it as guidance when modifying the Unreal AI Connection plugin, its C++ handlers, Python bridge, MCP setup, or related documentation.
Why use it?
It gives agents the project context and required reading they need before changing C++ or the bridge. This helps avoid working in the wrong area or missing project-specific constraints.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: reads ~/.codex or $CODEX_HOME, but also the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions subagents; mentions Claude Code.

This is NAJEMWEHBE/unreal-ai-connection's own configuration. It tells Codex and OpenCode how to work on unreal-ai-connection 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 unreal-ai-connection 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 B, and why

unreal-ai-connection AGENTS.md scanned grade B 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 10d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

The bridge is registered as `unreal-ai-connection` in this project's `.mcp.json` (read by Claude Code, Copilot CLI, Cursor). Codex CLI uses `~/.codex/config.toml` — register with:

How it starts

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — universal agent context for Unreal AI Connection

This file is read by Codex CLI, Copilot CLI, Gemini CLI, Cursor, and any other coding agent that respects the AGENTS.md convention. Claude Code reads CLAUDE.md instead (same content semantically; CLAUDE.md is the canonical version).

All agents: read docs/HANDOFF.md before any substantive work. The "Closing notes from prior sessions" section at the bottom of HANDOFF.md captures the operative state for resumption. The latest closing note wins if anything contradicts the at-a-glance counts at the top of HANDOFF.md.

Quick orientation

UE 5.7 plugin + Python bridge exposing editor automation to MCP-compliant clients (Claude Code, Codex CLI, Copilot CLI, Cursor, Gemini CLI, Continue, …) over a localhost TCP socket. 151 tools total: 114 native C++ handlers + 37 bridge-side synthetic tools. Vendor-neutral by design — the wire protocol is open MCP; the "Claude" in the repo name is decorative.

Where to look first

  • C++ handlers (106) — UnrealAIConnection/Source/UnrealAIConnection/Private/MCP/Handlers/Handler_*.cpp. Registered in UnrealAIConnectionModule.cpp.
  • Bridge-side synthetic tools (37) — bridge/unreal_ai_connection_bridge.py's SYNTHETIC_TOOLS dict: wait_for_events, get_camera_transform, set_camera_transform, screenshot_actor, compile_mod_pak, compile_mod_pak_direct, bulk_delete_assets, bulk_move_assets, bulk_rename_assets, bulk_duplicate_assets, bulk_inspect_assets, inspect_data_asset, inspect_sound_class, inspect_sound_submix, inspect_audio_bus, inspect_material_function, inspect_metasound, find_unused_assets, get_reference_chain, bulk_compile_blueprints, audit_blueprint_compile_status, find_actors_by_class, bulk_focus_actors, bulk_screenshot_actors, bulk_set_actor_property, compare_assets, bulk_set_console_variables, inspect_dependency_graph, bulk_fix_redirectors, marketplace_search, marketplace_import, convert_hdri_to_cubemap, sequencer_add_transform_keyframe, import_mesh, material_auto_remap, batch_capture_cameras, batch_spawn_from_csv.
  • Tool catalog (manual 3-place sync)UnrealAIConnection/Resources/mcp_manifest.json, bridge/unreal_ai_connection_bridge.py's TOOLS list, docs/TOOLS.md. tests/test_manifest_sync.py catches drift between the first two.
  • Architecture + UE 5.7 API gotchasdocs/ARCHITECTURE.md.
  • Host-build runbook — top of docs/HANDOFF.md.
  • Per-tool JSON schemas + examplesdocs/TOOLS.md.

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.
