Summary IDAssist is an IDA Pro plugin integrating LLMs for enhanced binary reverse engineering. It targets security researchers and engineers using IDA Pro, offering AI-assisted code analysis, function explanations, interactive Q&A, automated renaming, and a semantic knowledge graph to accelerate binary understanding.

How It Works Operating as a dockable panel within IDA Pro 9.0+ (Python/PySide6), IDAssist connects to diverse LLM providers (OpenAI, Anthropic, Ollama, LiteLLM). It analyzes decompiled functions, suggests renames, answers code queries, and builds a searchable knowledge graph. Its approach includes RAG for document search and an optional ReAct agent for autonomous, multi-round investigations, enabling deeper insights and automated analysis directly within IDA.

Quick Start & Requirements

• Installation: Recommended via hcli plugin install idassist. Manual installation requires extracting a release tarball to IDA's plugins directory and installing dependencies using IDA's bundled Python.
• Prerequisites: IDA Pro 9.0+ with Python 3 and PySide6. Hex-Rays Decompiler is highly recommended for pseudocode features.
• Dependencies: Python packages from requirements.txt.
• Links: Homepage: https://symgraph.ai. Detailed setup is in the "Getting Started" documentation section.

Highlighted Details

• Function Explanation: Generates natural-language explanations with security analysis (risk, API detection).
• Interactive Query Chat: Enables code Q&A with context macros and persistent history.
• Automated Actions: AI-driven rename suggestions for code elements, with confidence scores and review.
• Semantic Knowledge Graph: Builds and explores a graph of binary functions, calls, data flows, and security traits, featuring visual rendering and semantic search.
• RAG Document Search: Integrates uploaded reference documents (.txt, .md, .rst, .pdf) via Whoosh indexing.
• ReAct Agent: Autonomous agent for multi-round investigations, planning, tool execution, and reflection.
• MCP Integration: Connects to external MCP servers for tool-augmented LLM interactions.
• RLHF Feedback: Local feedback mechanism to improve prompt engineering and model selection.

Maintenance & Community No specific details regarding notable contributors, sponsorships, or community channels (e.g., Discord, Slack) were found in the provided README text.

Licensing & Compatibility License details are in the LICENSE file. Compatibility requires IDA Pro 9.0+; Hex-Rays Decompiler is recommended.

Limitations & Caveats Dependent on IDA Pro 9.0+. Hex-Rays Decompiler recommended for full features. Setup requires LLM provider configuration, potentially involving API keys or local hosting. The README does not specify alpha/beta status or list known bugs.
