TimeCodeSecurity – Deterministic AST SAST and Auto-Remediation for Python

Hi Hacker News! I built TimeCodeSecurity (TCS), an open-source static security engine for Python. Most existing open-source SAST tools rely on regex patterns or LLMs, leading to high false-positive rates and alert fatigue. TCS takes a compiler-level deterministic approach: it parses Python's Abstract Syntax Tree (AST) and tracks dataflow from function parameters directly into sensitive execution sinks (subprocess.run, raw SQL cursors, and path operations). Key highlights: - Deterministic AST taint tracking (Zero regex / Zero AI guessing) - Closed-loop remediation: Patches are validated via AST syntax compilation and re-scanned in-memory before touching disk - Chronological visual proof graphs: Source -> Taint -> Sink - Sub-second execution (~700ms) You can run it directly in your terminal: pip install git+https://github.com/kushigaur3103-svg/time-code-security.git tcs scan ./your_project --fix GitHub: https://github.com/kushigaur3103-svg/time-code-security Would love feedback on the AST traversal and in-memory verification approach! https://github.com/kushigaur3103-svg/time-code-security And that's my linkdin link https://www.linkedin.com/in/ayush-gaur-1488b1420?utm_source=share_via&utm_content=profile&utm_medium=member_android
