What Tested Fallback does

Pin an open-weights fallback model with a tested-on date and real smoke prompts, so a removed model results in a quick config change rather than lost time. Ideal when a model might be pulled or deprecated, you depend on a single model, or need failover.

Tested Fallback is cataloged under AI Engineering on DirSkills. Tested Fallback comes from a repository tagged agents, ai-agents, claude-code, claude-skills and codex.

Documentation

README

Excerpt

A backup you never ran is a hope

Models vanish for reasons outside anyone's control: export controls pulled Fable 5 days after launch, and ordinary deprecation calendars retire models constantly. The user's exposure isn't "will it happen" but "how big is the blast radius when it does". Your job is to shrink that radius to a one-line config change, and to refuse the most common self-deception in this area: a fallback that's listed but has never actually been run.
