  "account": "LifeOS is a local-first personal context and memory layer built for AI agents, created to address the issue of AI assistants forgetting essential user information. When conversing with an AI assistant, users must repeatedly explain their background, goals, and projects every time they open a new conversation. This leads to a frustrating experience, especially when users are feeling stuck or discouraged. LifeOS aims to solve this problem by providing a persistent context layer that AI agents can access, ensuring they have the user's most up-to-date information at hand.\n\nLifeOS accomplishes this by indexing a local vault of Markdown files into a PostgreSQL + pgvector instance using local ONNX embeddings. This process allows any MCP-compatible agent, such as Antigravity or local open-weight models, to retrieve personalized context with strict provenance. The Interaction Policy within LifeOS reads an explicit user document, how_i_want_ai_to_treat_me.md, which instructs the AI on how to separate emotion from evidence, challenge weak plans, and avoid empty reassurance. The system ensures that any memory retrieved by the agent includes exact source paths and headings, providing transparent provenance.\n\nQuarantined Memory Writes are another key feature, preventing agents from silently hallucinating or overwriting the user's canonical files. All agent-authored memories are strictly isolated to the vault/memory/ directory, complete with timestamps and metadata. The demonstration of LifeOS in action shows how it changes the behavior of AI agents. Instead of giving generic reassurance, the agent retrieves and evaluates the user's actual progress and milestones, providing targeted guidance tailored to their specific situation.",
  "summary": "This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend What I Built Most AI coding assistants suffer from severe amnesia. Every time you open a new conversation, context resets completely. You spend the first ten minutes re-explaining your tech stack, your active projects, your career goals, and how you want the AI to talk to you. Worse, when you hit burnout or feel…",
