Software teams lose critical engineering context over time. Important decisions are scattered across source code, commit messages, pull requests, review discussions, documentation, and past incidents. When developers need to understand why behavior changed, investigate a regression, or identify the cause of a bug, they often spend hours manually searching through disconnected tools. This becomes especially difficult for new team members, inherited projects, and fast-moving teams where the people who made the original decisions may no longer be available. EchoProof solves this problem by acting as an AI-powered decision memory for software teams. It ingests an authorized public or private GitHub repository and collects its engineering history, including commits, merged pull requests, discussions, changed files, README files, architecture decision records, and design documentation. Developers can then ask natural-language questions such as, “Why was authentication changed?” or “Which files are related to this behavior?” Instead of relying on one generic AI prompt, EchoProof delegates each question to multiple specialized investigation agents. The Code Investigation Agent examines relevant files and code relationships. The Git History Agent builds a timeline of related commits. The Pull Request Agent extracts motivations and decisions from descriptions and discussions. The Documentation Agent searches architectural records and project documentation. The Historical Incident Agent checks whether a similar problem has occurred before. These agents run in parallel, and an orchestrator merges and deduplicates their findings before producing a final response. Target users include software developers, maintainers, engineering leads, support engineers, DevOps teams, and new contributors onboarding to an unfamiliar codebase. Users interact with EchoProof through a simple web interface: they enter a GitHub repository URL, wait for ingestion to complete, submit a question, and receive a structured investigation containing the likely explanation, reasoning, confidence level, agent summaries, and clickable supporting evidence. What makes EchoProof creative is its focus on preserving the reasoning behind software—not only the current code. It combines repository knowledge and engineering history into a reusable organizational memory while keeping conclusions traceable to real evidence. Rather than presenting unsupported AI-generated claims, EchoProof highlights uncertainty and returns an honest insufficient-evidence response when repository data cannot support an answer. By running specialized investigations concurrently and presenting consolidated results in one place, EchoProof reduces repetitive searching, shortens debugging and onboarding time, and helps teams make faster, better-informed engineering decisions.
