v0.3.4-beta

🚀 Codebadger Release — v0.3.4-beta

Released: Dec 14, 2025

📦 What’s New

🧠 New Analysis Tools (get_cpg_*)

We introduced new CPG-based inspection tools to improve structural and semantic analysis:

Tool	Description
get_cfg	Retrieve the full Control Flow Graph (nodes and edges) for a method
get_type_definition	Extract struct / type definitions including their members
get_macro_expansion	Detect potential macro expansions using heuristic analysis

These tools provide more explicit program structure access for agents and downstream analysis.

---

🔄 Refactors & Improvements

• Major refactor of find_taint_flows for clearer logic and improved maintainability.
• Refactored get_data_dependencies to improve correctness and extensibility.
• Performed a large-scale refactor of tools to standardize behavior and interfaces.
• Updated all tool descriptions to follow a single, consistent definition format, making them easier for LLM agents to understand and use.

---

🧹 Removed / Deprecated Tools

The following tools were removed due to low utility or redundancy:

• find_argument_flow
• find_literals
• check_method_reachability

This cleanup reduces noise and keeps the toolset focused on high-impact analysis primitives.

---

🛠️ Maintenance

• Improved clarity and consistency of tool descriptions across the codebase.
• Version bumped to v3.3.4-beta.

🚀 Release Notes — v0.3.0-beta

✨ Improvements

🔌 Joern Query Execution via Server

• Queries are now executed directly on a Joern server instead of using pipes.
• This significantly improves stability and reduces overhead.

⚙️ Asynchronous CPG Generation

• CPGs are now generated asynchronously.
• All codebases now share a single Docker container, replacing the previous multi-container setup.

📈 Enhanced Logging

• Improved and more structured logging for easier debugging and observability.

⚡ Faster Query Execution

• Query runs are now faster thanks to avoiding reloading the CPG each time.
