What is Codemode (Armin Ronacher)

blog post · Story page

A split picture. On the left a figure reaches into one drawer of a tall rack of bolted-in tool drawers. On the right the same figure joins two simple parts into a new tool at a workbench and puts it on a shelf.

Pi 1.0 added MCP support through Codemode, and Ronacher uses the occasion to revisit what a harness should hand a model at all. His case for CLI and bash is composition, plus the fact that a model trained on the filesystem knows echo foo > /tmp/test.txt leaves a file behind.

In plain words

  • Pi added a new way for its artificial intelligence assistant to use tools.
  • Pi's developer says training teaches assistants how typed commands affect files, including when a command creates a file.
  • For developers, commands that assistants already understand can be combined to carry out larger tasks.
