Malleable software: Restoring user agency in a world of locked-down apps
The original promise of personal computing was a new kind of clay. Instead, we got appliances: built far away, sealed, unchangeable. In this essay, we envision malleable software: tools that users can reshape with minimal friction to suit their unique needs.
My current theory of agentic programming: people are amazing at adapting the tools they're given and totally underestimate the extent to which they do it, and the amount of skill we build doing that is an incidental consequence of how badly the tools are designed.
A comprehensive guide outlining best practices for building reliable, user-friendly Model Context Protocol (MCP) tools with proper configuration, testing, and release management.
