Open-source Agent Fieldbook turns Anthropic and OpenAI docs into reusable skills

whitewust · reddit · 2026-07-22

The author built Agent Fieldbook, an open-source repo that turns official Anthropic and OpenAI documentation and courses into reusable, source-backed agent skills.
The motivation: Claude Code and Codex often make sensible project/workflow decisions, but those decisions can lag behind the latest official guidance.
The goal is not to replace the source materials, but to make them available at decision time when agents are actually working on real codebases.
The project is early and the author is asking for feedback on skill structure, traceability, scope, and which recurring agent mistakes should be covered next.
