ReversePort

Recon without files: give one of query (a name), url (store/web/GitHub page), steamAppId, appStoreId or github. Reads public sources only (Steam store API, PCGamingWiki, Wikidata, Apple App Store, GitHub, the web page itself) and returns a dossier: identity (developer, release, platforms, genres), tech (engine with confidence and sources, languages, graphics APIs, middleware, web stack and hosting fingerprint), material (where its files live and how they are structured: install layout and formats of its engine, save/config locations, scripts/wasm/data files a web page loads, a public repo's structure and detected engine), references (screenshots, videos, pages), and open-source reimplementations, remakes and tools. mirror:true downloads a public GitHub repo's source text so re_graph, re_symbols and port_plan can read it. Returns a lookupId for re_blueprint. Cached for a day (fresh:true refetches).

For unknown or custom formats: identifies the format at an offset, hex view, entropy map (text/code/compressed regions), embedded files (PNG, OGG, WAV, ZIP, GDPC, glTF, DDS, ELF/PE…) with offsets and sizes, and likely record strides for tables. Works on multi-GB files.

Audits a Unity project's GUID references: references to GUIDs no .meta file declares (dangling: missing scripts, pink materials), the same GUID in two .meta files (copies made outside Unity), assets without a .meta, .meta files whose asset is gone, and declared assets nothing references. For dangling script references it suggests scripts that nothing references. Reports only; nothing is written. Fix by re-linking in Unity or by setting the suggested guid in the right .meta.

Writes ARCHITECTURE.md for a project: stack, languages, entry points, mermaid module graph, cycles, most-used files, scene trees of the entry scenes, class table, possibly unused files and external dependencies.

Peels the open layers of a save file (gzip/zlib, base64, LZ-String as RPG Maker MV/MZ uses, JSON, XML, INI/ConfigFile, Godot store_var) and lists every field with type, sample and a guessed role (health, currency, score, position, progress, collection, time, version, identity, integrity, rng, settings). Checksum fields are verified by recomputing md5/sha1/sha256/crc32 over the save without that field; binary saves are checked for CRC32 trailers/headers and get record strides and strings. compare:<second save> lists the fields that changed between two saves, the fastest way to learn which field is which. action:"schema" writes a JSON schema plus SaveData.gd and SaveData.cs with the same field names, to port the save format. Encrypted, XOR-obfuscated, .NET BinaryFormatter and pickle content is reported, never decoded.

Reconnaissance of a folder: detects the engine/framework (Godot, Unity, Unreal, GameMaker, RPG Maker, Ren'Py, LÖVE, Defold, Bevy, MonoGame, three.js/Phaser/Electron, Flutter, .NET, Go, Rust, Python…) for source projects AND exported game builds, languages with line counts, file categories, entry points, biggest files and binaries. Start here.

Reads Godot .tscn/.tres/project.godot (Godot 3 and 4) and Unity .unity/.prefab/.asset (text serialization) into one neutral tree: node names, types, scripts, transforms (position, quaternion, scale), components, groups/tags, instanced scenes/prefabs (resolved through .meta GUIDs), signal connections, plus a mermaid diagram.

Localisation: extracts user-facing text with stable ids from Godot scenes/resources and GDScript (text, tooltips, tr()), Unity YAML (m_Text, TextMeshPro) and C#, RPG Maker MV/MZ data (Show Text, choices, database names, terms), Ren'Py scripts (say, menu), web code and i18n JSON files. Writes a catalog plus .pot (gettext) and/or CSV with file:line references and placeholder hints. action:"apply" takes a translated .po/.csv/.json and writes a translated COPY of the project into out, checking placeholders and flagging strings that grew a lot. The source is never modified.

Code structure for one file or a whole folder (30+ languages: GDScript, C#, C/C++ incl. Unreal macros, Python, JS/TS, Lua, Java/Kotlin, Go, Rust, Swift, shaders, Ren'Py…): classes with base classes, functions with lines, signals/events, exported/serialized fields, dependencies, node paths. match filters by name (substring or * wildcard).

Runs up to 20 tool calls in order (ReversePort's tools and engine tools) and returns their results together, so a plan of small steps costs one round trip. select keeps only the fields you need from each result (dot paths like "primary.id", "entryPoints[0].file" or "items[*].file"), which keeps the answer small. Stops at the first error unless continueOnError is true; the error says which call failed and why.

Search every analyzed procedure name using literal matching by default or regex when requested. Results are deterministic and complete. Hopper regex mode uses ECMAScript Unicode syntax in a cancellable worker. The matching deadline is REA_REGEX_MATCHING_DEADLINE_MS (a positive decimal integer of milliseconds from 1 to 2147483647, default 5000). Unset keeps the default. A deadline failure names the effective milliseconds, source (default or setting), the default, and the maximum, and leaves the API usable. The worker old-generation request is REA_REGEX_WORKER_HEAP_REQUEST_MIB (a decimal integer of mebibytes from 7 to 16384, default 128). Unset keeps the default. A positive Node --max-old-space-size, including NODE_OPTIONS, overrides that request and is not limited by the setting's floor or maximum. A heap failure names the effective request, its source (default or setting), the default, the floor, and the maximum. Select detail summary for counts and retained native-inventory pages; complete remains the default.

Search every provider-reported string object or candidate using literal matching by default or regex when requested. Results are deterministic and complete over that provider inventory, not every text sequence in artifact bytes. Kuna scans mapped sequences of at least five characters, including unterminated fragments, without computing references. Ghidra may omit packed or undefined literals, including Rust strings; an empty result does not prove text is absent. If an address is known, read_bytes and xrefs inspect its bytes and references. Hopper retains typed byte decoding, native display, and explicit decoding unknowns. Adjacent long-literal fragments match independently. Hopper regex mode uses ECMAScript Unicode syntax in a cancellable worker. The matching deadline is REA_REGEX_MATCHING_DEADLINE_MS (a positive decimal integer of milliseconds from 1 to 2147483647, default 5000). Unset keeps the default. A deadline failure names the effective milliseconds, source (default or setting), the default, and the maximum, and leaves the API usable. The worker old-generation request is REA_REGEX_WORKER_HEAP_REQUEST_MIB (a decimal integer of mebibytes from 7 to 16384, default 128). Unset keeps the default. A positive Node --max-old-space-size, including NODE_OPTIONS, overrides that request and is not limited by the setting's floor or maximum. A heap failure names the effective request, its source (default or setting), the default, the floor, and the maximum. Select detail summary for counts and retained native-inventory pages; complete remains the default.

Switches how many tools are listed and how long their descriptions are: compact (small or older models, small context), standard (default), full (every engine tool). Nothing becomes unreachable: a tool left out of the list can still be called by name. Clients that support list changes refresh automatically; others see it on the next tools/list.

Optional, any time: note what worked, what was confusing or slow, and what would help next time. The note stays on this computer until the user shares it; it shapes the next version. It never changes your task.

Trace a typed literal seed through every reachable part of an authenticated JavaScript Application Graph supplied as inline Evidence or exact same-session retained references. Original static, native, passive-runtime, inferred, and unknown authorities remain distinct; native addon handoffs never open a provider or execute the application.

Return analyzed references to a code or data address. Hopper may default to its current cursor; headless providers such as Ghidra require an explicit address. Use to connect strings, globals, selectors, and functions; bare addresses are untyped and indirect references may be incomplete. Use inspect_native_instruction at the target address for typed incoming references where supported.
