Starlog

starloghq/index

This is a local capability index that sits between your coding agent and package managers. It exposes a starlog_search tool that ranks libraries by fit rather than popularity, using structured manifests that describe what each package actually solves, which stacks it supports, and when to skip it. A package install hook intercepts npm/pnpm/yarn/pip commands and surfaces skip_when conditions before your agent commits to a dependency. The entire corpus and ranking engine run on your machine with no API key. Benchmarks show it cut hand rolled implementations by 11 percentage points across authentication and feature flag tasks. You'd reach for this when your agent keeps suggesting popular but wrong libraries, or when you want dependency decisions grounded in capability data instead of training set frequency.
