Appreciate it. SurvivalIndex is agnostic to LLM or coding agent. One of the more interesting findings when you run the same
prompts across Claude, GPT, and Copilot is that tool
selection diverges significantly by model. Claude Code picks
Drizzle for ORM in JS at 100% on Opus, while Sonnet still
defaults to Prisma at 79%. Older models route to Redis for
caching, newer models increasingly go Custom/DIY. The
"recency gradient" shows up clearly — newer models pick
newer tools, sometimes before the ecosystem has validated
them.
This matters because a tool's survival score shouldn't be
measured against one agent. A tool that only one model
knows about has a structural awareness problem. A tool
three models independently converge on has something real.
