Profile

As a Security Engineer with over 10+ years in industry, I kept running into the same problem with coding agents: Instructions are not guarantees.I put guidance in `CLAUDE.md`, `AGENTS.md`, memory files, MCP descriptions, and tool documentation. I explicitly told the agent things like:- Use the code graph for architecture questions instead of grepping the repository. - Do not use deprecated APIs or Unsafe code. - Prefer specific tools for specific tasks.The agent would still ignore those instructions surprisingly often. It would grep the entire repo, use deprecated APIs, or choose a slower tool even when a better one was available.That made me realize prompts and rules solve different problem

Sigmashake Desktop – AI Coding Agent Guardrails is positioned in show hn launch, a segment that rewards a clear, focused offering.

Directory data places it at the Show HN launch stage.
