ddc is a Rust command-line Android decompiler that converts DEX bytecode from APKs and related containers into readable Java. It supports multi-dex applications, XAPK/APKS/APKM packages, DEX versions 035–041, lambdas, string concatenations, and selected Android and Kotlin-specific output transformations. Its progressive-analysis interface provides subcommands for inspecting application metadata, manifests, resources, strings, cross-references, classes, methods, disassembly, and class hierarchies without requiring a complete decompilation first. The repository reports that its generated Java output passes a javac syntax check across its validation corpus and uses deadline-bounded processing for pathological classes. The CLI can be installed through Homebrew, Scoop, cargo-binstall, or built from Rust source. It provides bilingual English and Simplified Chinese messages, emits reproducible output without timestamps, and is released under the MIT license.

Reverse Engineer Anything is an AI-agent workflow that decompiles native binaries, including ELF and PE files, JVM bytecode, firmware, and container layers, into human-readable pseudo-code.

Universal Modder is an open-source toolkit by rehan-remade for AI coding agents that create offline, single-player mods for PC games. Its skills and tools identify a game's engine and existing modding route, inspect code and files, back up saves, build a working mod slice, generate art, 3D assets and audio through the fal MCP server, test the result in the running game, package it, and record findings for later agents. The repository supports Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and other agents that read AGENTS.md, and includes the Python `um` CLI for game scanning, asset generation and processing, Windows automation, save management, video capture, publishing checks and a shared knowledge base of game-specific field notes. Its rules restrict use to games owned by the user and offline or single-player work; they prohibit online cheats, anti-cheat or DRM bypasses, and distributing game files or decompiled code. The repository is MIT licensed and requires Python 3.10+ and ffmpeg; Blender is used for 3D-to-sprite rendering.

Droid ASC is an Android APK decompiler front end for mobile researchers and agents. It treats compiled APK and DEX data as a read-only database, querying code relationships on demand instead of building large global indexes or fully inflating all artifacts. The engine probes Deflate bitstreams directly, uses dense Huffman lookup tables to extract metadata, exploits R8's deterministic constant relocation and instruction deduplication for cross-DEX searches, and resolves bytecode offsets to methods with an O(1) instruction-location primitive. When a target is found, it extracts the target bytecode and dependencies and reconstructs a minimal self-contained DEX in memory for decompilation. It is distributed as the `droidasc` Python CLI, installable from PyPI or source. Its commands locate and decompile classes, decode `AndroidManifest.xml`, and find string, type, method, or field references across an APK's DEX entries. The README reports a demonstration against a 352 MB commercial APK in which cross-reference search took 1.79 seconds and target-class decompilation took 177 milliseconds using 141 MB of RAM.

agentplay is an open-source command-line tool and local web viewer maintained by Entelligence AI for replaying coding-agent sessions as a map and timeline. It discovers session data from Claude Code, Codex, Cursor, GitHub Copilot, OpenCode, and Kiro, parses transcripts or local database stores into redacted agentplay/v1 JSON maps, and serves them from a local viewer. The session map records files and repositories touched, shell verbs, tools, MCP servers, models, subagents, errors, retries, delays, outputs, token counts, and timing without storing prompt or assistant text, tool inputs or outputs, file contents, or command arguments. The viewer provides a radial session map, playback with step or wall-clock time, error and retry navigation, task and subagent scopes, and import/export of map files. It runs locally without an account or API key; session data remains on the device, with an optional email-signup network request that can be disabled. The CLI requires Python 3.11 or newer, has no runtime dependencies beyond the standard library, and is distributed under the Apache License 2.0.
