About

This site teaches developer work with Claude / Claude Code, ChatGPT / Codex, and Gemini / Gemini CLI. Shared methods sit alongside independently researched product guides. The existing Claude library remains available with its own scope.

How the guides help

Guides lead to a concrete task, explain common failures, and show how to check the result. Repeatable tasks have pipeline recipes with explicit human decisions. Model roles are candidates to evaluate on your own work.

The website does not execute pipelines or receive repository contents. The reference package runs locally with synthetic data by default. It can also supervise configured CLI stages between human decisions. Its documentation distinguishes executed tests from unverified live integrations.

Sources and verification dates

Product facts come from primary sources. Examples and methods are editorial proposals; research is presented with its limits. Guides list sources, access dates, and their last verification date. Model records carry individual verification dates.

The freshness check warns at 90 days and fails at 180 days. Stale content fails the scheduled maintenance pipeline; ordinary pipelines receive a warning. Source rules
