Developer Builds AI Argument Debugger in Three Days for AWS Hackathon

A developer built MindMap Debugger, a tool that scans text for logical contradictions and circular reasoning, as part of the WeMakeDevs AWS First Commit hackathon. The tool accepts any pasted argument or transcript, uses an LLM via Groq's API wrapped in AWS's Strands Agents SDK, and flags claims that conflict or loop back on themselves. Without a debit or credit card for AWS signup, the developer switched from the 'Ship It' track to the 'Build It' track while still meeting the AWS-native tooling requirement. Key challenges included a reasoning model leaking its internal chain-of-thought into outputs and non-deterministic extraction results, the latter solved by running three parallel extractions and merging consensus findings. The project also required a similarity-matching fix after the model paraphrased identical claims differently across runs, causing duplicate propositions to slip through the merge logic.
