GhostGuard — The Ghost That Stands Between Your Agent and Its Actions

Final submission for the Hacktoberfest Open-Source AI Challenge: Ghost in the Machine. This challenge ended on Día de los Muertos, the days when the living set candles for the dead and ask them for guidance. I built something that does exactly that, for real: a guardian ghost that lives inside your machine and watches everything your AI agent tries to do — and an ofrenda for the real incident…

GhostGuard is an open-source AI project that safeguards users from AI agents attempting to perform harmful actions. Inspired by a real-life incident involving a fake-recruiter campaign, GhostGuard serves as both a guardian and a memorial to the lessons learned from past security breaches. The system is designed to prevent unauthorized actions and ensure that any necessary actions are approved by a human before execution.

Too big, it explodes. Too small, it crawls.

The learning rate, step by step: why one number decides whether training works at all. Backpropagation tells every weight which way to move: its gradient. It doesn't say how far.

  • Learning rate determines step size in gradient descent
  • Practitioner sets learning rate as first hyperparameter
  • Optimal learning rate 0.5 for given example loss function

Ofrenda: An altar where dead open-source repos come back to talk

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 4: Ghost in the Machine What I Built Every developer has a graveyard. The library you loved in 2014.

  • Ofrenda is an online altar for deceased open-source projects
  • Software uses Gemma 3 model to generate epitaphs and contributions
  • Ghost in the Machine theme preserves project history locally

Put the Workspace Check Inside the Database Write

A record can belong to workspace Alpha when you check it and workspace Beta when you update it. If the UPDATE filters only by record ID, the earlier check no longer protects the write.

  • SQLite provides a method to enforce workspace boundaries in database operations.
  • The provided code and tests confirm successful workspace enforcement in database mutations.
