I got tired of brittle literals like `http://localhost:3000` and `postgres://…@127.0.0.1/...` creeping into my code, so I wrote a few ESLint rules that detect “hardcoded infrastructure” strings and ask the agent to find the constant in the codebase — not by guessing its name but by `grep`-ing for its value.

The detection is based on dumb string literal heuristics, but has proven rather effective. Example patterns:

const hardcodedInfrastructure = { url: /^https?:\/\/(localhost|127\.0\.0\.1|192\.168\.\d+\.\d+|10\.\d+\.\d+\.\d+|172\.(1[6-9]|2\d|3[01])\.\d+\.\d+)(:\d+)?/i, dbUrl: /^(postgresql|postgres|mysql|mongodb):\/\/.*@(localhost|127\.0\.0\.1|192\.168\.\d+\.\d+|10\.\d+\.\d+\.\d+|172\.(1[6-9]|2\d|3[01])\.\d+\.\d+)/i, localhost: /^localhost$/i, localhostPort: /^localhost:\d+$/i, };
