• build_and_deploywrite action

  Compile a mod project and deploy the output to the game mods directory.

• debug_mod

  Analyze mod logs to diagnose errors and suggest fixes.

• decode_assets

  Universal Asset Decoder. Reads a PR-1 autopsy catalog, cracks open Unity .assets containers, and decodes their members back into The Model (decoded=1, decoded_path set): Texture2D -> PNG (streamed pixels from sibling .resS), Mesh -> glTF .glb + .obj (plain/uncompressed; compressed noted+deferred), and AudioClip -> WAV (PCM) / OGG (bare Vorbis); FSB5-wrapped Vorbis + other codecs are noted+deferred

• detect_engine

  Scan a game directory and detect what engine it uses (Unity, Unreal, Godot, Java, etc.). Returns engine type, runtime, and primary assembly path.

• disassemble_function

  Disassemble a function starting at an RVA in a native PE (x86-64). Linear sweep from the entry RVA to the first terminal instruction (ret/iret) or max_bytes, whichever comes first — a PR-3.1 boundary heuristic (CFG-accurate bounds arrive with the call-graph in PR-3.2), so the function EXTENT is tagged provenance=inferred while the decoded bytes themselves are verified. Read-only on the binary. Wri

• disassemble_range

  Disassemble an arbitrary byte range of a native PE (x86-64) starting at an RVA. Resolves the RVA to its section and file offset, reads ONLY that slice (read-only on the binary), and decodes it with Capstone. Returns the instruction listing. If db_path or game_path is given AND the binary is catalogued in that autopsy DB, the decoded instructions are also summarized into The Model as a 'function' r

• find_gameplay_values

  Search for gameplay-related values (health, damage, speed, money, etc.) across the game code. Works with any engine by using the appropriate search tools.

• find_steam_games

  Search configured Steam library paths for installed games. Optionally filter by name.

• game_status

  Get the current session state including loaded game, engine type, cached analysis data, and mod build status.

• list_available_tools

  List all tools available for the currently loaded game engine, grouped by category.

• load_game

  Set a game as the active modding target. Auto-detects engine, sets up session state, and returns what tools are available for this game type.

• mod_this_game

  End-to-end game modding assistant. Detects engine, analyzes game structure, and returns a modding plan with available tools and next steps. Start here when modding a new game.

• scaffold_mod

  Generate a mod project skeleton from templates. Creates project files, plugin class, and build configuration.

• unpack_game

  CATALOG-FIRST universal unpacker. Recursively walks an ENTIRE game install, classifies and sha256-hashes EVERY file, and persists the catalog into a SQLite <game>.autopsy.db (game/binary/asset/data_store tables, provenance on every row). Read-only: never writes game files. Containers (.pak/.pck/.bundle/...) are catalogued as single rows, never expanded (per-format extraction is a later slice). Ide
