Make your coding agent reliable on your codebase

A hands-on curriculum for engineers. Write the skills your agent needs, test that they work, and ship them to your team.

Two ways through: read the lessons here, or run them hands-on in your own coding agent: Claude Code, Cursor, Codex, or Tessl Agent.

1 · Install oncenpx tessl install tessl-academy/skill-foundations
2 · Start lesson 1: ask your agentguide me through skills in 30 minutes

Install in a fresh project directory (for example a new foundations folder, because Tessl won't initialize in your home directory). Full walkthrough in the Quickstart.
