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.

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.
Skill Foundations
Start here. What a skill is, how to write one, and how your coding agent reaches for it on intent.
Tuning Your Agent
Put numbers on your agent's output and improve it deliberately. Review evals, task evals, and the optimizer. Measure quality, then move the bar.
Code Review Loops
Add an agentic reviewer to your pull requests, teach it the conventions only your team keeps, and close the loop so each round knows what the last one settled.
