I would love the idea of a technical credit score. For example, if you’re the kind of dev that racks up technical debt and never pays it down, you should have a shitty technical credit score, and be considered a poor hire. Whereas someone with great credit, would be a great asset to bring onto the team.
Tracking "credit" score sounds like good idea, but I would not go as far and assuming that persons with bad credit scores are poor hires.
Maybe person who creates tech debt is really great at prototyping, fixing urgent issues with unconventional methods (aka MacGyver) or do other tasks you find boring. While credit score of this person will be low, such people are also great assets in the team.
In general, this metric could be useful as tracking number of pull requests, lines of code, and so on: to spot anomalies and investigate: maybe that person is suddenly blocked by something, overwhelmed and need help, or just works differently, or on different tasks and the anomalous metric is ok.
